Taxing Extraction, Not Enterprise — A Realization-Based Model for Inheritance Tax Reform in Germany and the United States

Abstract

This paper proposes a reform of inheritance taxation organized around a single principle: tax the extraction of value from a productive enterprise, not its inheritance. Under the model, an inherited operating business passes to heirs subject only to a modest baseline levy; no further tax is due as long as the enterprise continues operating and value is not extracted from it beyond ordinary, documented limits. A high tax rate applies not to "selling" as such, but to extraction — cashing out, winding down, or stripping the enterprise of its productive capacity — while a sale that keeps the enterprise running and its jobs intact is taxed at a materially lower, graduated rate. The paper situates this proposal against existing law — Germany's §§13a/13b ErbStG business-asset relief and the US stepped-up-basis regime already embody partial versions of the same logic — and against the public-finance literature on the capital gains "lock-in effect," the closest analytical cousin to the mechanism proposed here. It then works through eight predictable objections — debt-financed extraction, corporate-wrapper restructuring, constitutional proportionality, capital misallocation in unviable firms, successor incapacity, revenue volatility, regressivity relative to the policy's own equal-opportunity aims, and valuation gaming — and answers each with a specific, named design mechanism grounded in existing law or the academic literature, including a self-assessed valuation mechanism adapted from the Harberger/common-ownership-self-assessed-tax literature and a universal opportunity endowment adapted from Atkinson's capital-endowment proposal and Ackerman and Alstott's stakeholder grant. A companion proposal eases the marginal income tax rate around €100,000 toward roughly 20%, financed by an automatic fiscal trigger tied to realized receipts rather than by assumption.

1. Introduction and Problem Statement

Inheritance taxation sits at the intersection of two goals that are in genuine tension: raising revenue and preserving intergenerational fairness of opportunity, on one hand, and avoiding the forced breakup of productive, job-creating assets on the other. Conventional inheritance and estate taxes are levied on the transfer itself, valued at fair market value at the moment of death or gift. For a family business, a farm, or a concentrated equity stake, this creates a well-documented problem: heirs who have no liquid cash may be forced to sell all or part of a functioning enterprise merely to pay the tax bill, even when keeping the business intact would have been the economically and socially preferable outcome.

This paper proposes reframing the trigger for taxation. Rather than taxing the transfer of ownership, it proposes taxing the extraction of value from the inherited enterprise — cashing out, winding down, or stripping it of productive capacity — while leaving the enterprise itself untaxed as long as it keeps operating and its jobs are preserved. The goals are to discourage unnecessary liquidation, preserve jobs and productive capacity, and support a reading of "equal chances" in which each generation starts on comparable footing rather than one in which advantage compounds indefinitely through concentrated, undisturbed capital.

A companion proposal eases the income tax burden on middle-income earners — a marginal rate of roughly 20% starting around €100,000 of income — on the theory that lighter taxation of active labor and business income channels more capital into new venture formation.

A rule this simply stated invites predictable objections: that it can be circumvented by debt extraction or corporate restructuring, that a design very close to it has already been found unconstitutional once in Germany, that it risks entrenching economically unviable firms, that it presumes a willing and able heir who often does not exist, that it produces unpredictable revenue, that it can be regressive relative to its own stated aim, and that it invites valuation gaming. Section 5 takes each objection in turn and proposes a specific mechanism to answer it. The resulting design is more complex than the one-line version of the idea, but the complexity is the price of a version that could actually function as legislation rather than merely as an intuition.

2. The Proposal, Formally Stated

We define the core rule as follows:

Extraction-Based Inheritance Tax (EBIT): An inherited productive enterprise — an operating business, farm, or controlling equity stake — passes to heirs subject to a modest baseline levy. No further tax is due as long as the enterprise continues operating and value is not extracted from it beyond ordinary, documented limits. Tax at a high rate — illustratively 90% — applies to extraction: cashing out, winding down, or stripping the enterprise of its productive capacity. A sale that keeps the enterprise running and its jobs intact is taxed instead at a materially lower, graduated rate.

The distinction between extraction and a going-concern sale is the single conceptual move that does the most work in this proposal, because it targets the thing the policy actually cares about — whether the enterprise and its jobs survive — rather than a proxy for it, such as whether the family happens to still own it. Section 5.4 develops the mechanism behind this distinction in detail; Section 6 assembles it, together with the other seven mechanisms introduced in Section 5, into a single integrated statutory sketch.

3. Existing Precedent: This Idea Is Already Partly Law

A useful scientific discipline is to ask whether a mechanism already exists somewhere, even partially. It does, in both jurisdictions this paper targets, which is a point in the proposal's favor — it is not inventing an untested mechanism from nothing.

3.1 Germany: §§13a and 13b ErbStG

German law already exempts up to 85% (Regelverschonung) or 100% (Optionsverschonung) of the value of qualifying business assets from inheritance and gift tax, conditional on two things: the heir must continue operating the business for five years (85% relief) or seven years (100% relief) — the Behaltensfrist — and the cumulative wage bill (Lohnsumme) must not fall below 400% (five-year option) or 700% (seven-year option) of its pre-transfer baseline — the Lohnsummenregelung. If the heir sells or discontinues the business within the retention period, relief is clawed back retroactively (Nachversteuerung) in proportion to how early the disposal occurred. For estates of qualifying business assets above €26 million, a sliding-scale reduction (Abschmelzmodell) phases the relief down to zero at €90 million, or the heir can request a means-tested needs assessment under §28a ErbStG.

This is structurally the same idea proposed here, and the design in this paper follows German law in three respects that a simpler, unconditional version of the idea would not: relief is large but not unconditionally 100% by default; it is time-bound rather than permanent, so it does not create an indefinite lock-in; and it is tied to a job-preservation metric (the wage bill), not merely to the absence of a sale.

3.2 The United States: stepped-up basis and QSBS

The US system embeds a related but distinct mechanism. Under current law, an heir's cost basis in an inherited asset is "stepped up" to its fair market value at the date of death, erasing any unrealized capital gain the decedent had accrued — the heir pays no capital gains tax on appreciation that occurred before inheritance, and no tax at all is due unless and until the heir sells. Separately, federal estate tax applies only above a large exemption — $15 million per individual and $30 million per married couple in 2026 under the One Big Beautiful Bill Act (OBBBA), which made permanent an exemption level that had been scheduled to fall to roughly $7 million on the TCJA's 2025 sunset — at a flat 40% rate on the excess. Only a very small share of estates (well under 1%) owe any federal estate tax at all.

The US system therefore already achieves something close to "no tax while held, tax only realized gains" for the middle and upper-middle class simply because the exemption is so high, combined with the basis step-up. This proposal effectively asks: what if the same logic — no tax on holding, tax only on realization — applied below that exemption too, but at a much higher rate specifically triggered by extraction?

Figure 2. US federal estate-tax exemption per individual, 2017-2026. OBBBA (2025) made the $15M 2026 exemption permanent rather than letting it revert to roughly $7M.

4. Theoretical Grounding: The Lock-In Effect, Inverted on Purpose

The relevant body of economic theory here is not inheritance-tax literature specifically but the public-finance literature on realization-based capital gains taxation, because the mechanism is formally identical: tax is deferred until an extraction event, which changes the incentive to extract. This is known as the lock-in effect, documented since at least Feldstein and Yitzhaki's work in the 1970s and formalized in general-equilibrium asset-pricing terms by later authors. The core finding, replicated across decades of empirical and theoretical work, is unambiguous in direction: realization-based taxation depresses realization rates, and the size of the effect grows with the tax rate applied at realization. Because US law also steps up basis at death, the lock-in effect is strongest exactly at the point of inheritance — heirs already have a strong incentive not to sell, since selling is the only event that crystallizes tax.

This proposal deliberately adopts this well-known distortion and amplifies it, on the theory that in the specific case of an operating business, the distortion (not extracting value) is the socially desired outcome (jobs preserved, the enterprise continues) rather than an unwanted side effect, as it usually is when it discourages investors from reallocating capital to better uses. This reframing is intellectually coherent — the same mechanism can be a bug in one context and a feature in another — but it inherits the mechanism's other, less convenient properties along with the one that is wanted, which is why Section 5.4 in particular narrows the rule to extraction specifically rather than to any change of ownership.

Figure 3. Conceptual illustration of the lock-in effect: as the tax rate applied upon a realization event rises, the empirical literature finds voluntary realizations fall, non-linearly, consistent with findings from Slemrod (1978), Kiefer (1990), and the Penn Wharton Budget Model's 2022 analysis of the same mechanism in US capital gains policy. Values here are illustrative of the documented direction and curvature, not a calibrated forecast for this specific proposal.

A second relevant strand is the theory of equality of opportunity that this proposal invokes explicitly. In welfare economics, a meaningful distinction exists between equalizing starting conditions (opportunity) and equalizing outcomes. A tax that is neutral on transfer but punitive on extraction does not, by itself, equalize starting conditions between an heir who inherits a business and one who inherits nothing — it only constrains what the first heir may later do with what they received. Section 5.7 addresses this directly, since it is the one objection that goes to the proposal's own stated justification rather than to its mechanics.

5. Eight Objections and Their Design Responses

Each subsection below states a predictable objection to the core rule in Section 2, proposes a specific mechanism to answer it, grounds that mechanism where possible in existing law or the academic literature, and states honestly what the mechanism does not fully resolve.

5.1 Debt-Financed Extraction — The Cumulative Extraction Ledger

Objection: the rule as stated in Section 2 only taxes extraction through a sale or formal liquidation. It says nothing about debt. An heir can borrow heavily against the business — a leveraged dividend recapitalization — extract most of its value in cash immediately, and leave a debt-laden but nominally "still operating" shell behind. No sale has occurred, so the high rate never applies, yet the economic substance is identical to a partial liquidation.

Design response — the Cumulative Extraction Ledger

Every enterprise under deferral maintains a Cumulative Extraction Ledger recording all payments to the heir or family beyond a documented reasonable-compensation benchmark and an ordinary dividend allowance (capped at, e.g., the enterprise's pre-inheritance five-year average payout ratio). Debt-financed distributions, related-party asset transfers below market value, and management fees to family members above benchmark all count against the ledger. Once cumulative extraction crosses a threshold — illustratively 30% of the certified inheritance-date value (Section 5.8) — the excess is deemed a taxable extraction event and taxed immediately at the high rate, even though no formal sale occurred.

Grounding: this is a deemed-realization approach, structurally similar to anti-abuse provisions that already exist in both German and US tax law to recharacterize disguised distributions and related-party transactions according to economic substance rather than form.

What remains open: setting the reasonable-compensation and ordinary-dividend benchmarks correctly is itself contestable and would generate the kind of valuation and characterization disputes that already occupy much of existing closely-held-business tax law; this mechanism narrows the debt-extraction channel rather than closing it with certainty.

5.2 Corporate-Wrapper Restructuring — Substance-Based Realization with Productive Rollover

Objection: "selling the company" and "selling shares in a holding company that owns the company" are legally distinct events that a drafter would need to treat identically, or the second becomes a free pass. A merger in which the heir receives stock in the acquiring company rather than cash is not obviously an extraction event under a literal reading, even though control and ultimate ownership have both changed.

Design response — substance-based realization with rollover

A realization event is defined by economic substance: any transaction that converts the heir's stake into cash, cash equivalents, or freely tradable marketable securities counts as a realization, classified as a going-concern sale or an extraction event under Section 5.4 depending on what happens to the underlying enterprise. Explicitly exempted is a Productive Rollover: an exchange of the stake for a controlling or materially significant, illiquid stake in another operating enterprise, where the capital remains productively invested and at risk rather than being converted to cash. This mirrors the logic of a like-kind exchange — the point is not to punish restructuring, only cashing out.

Grounding: the productive-rollover concept is analytically the mirror image of the lock-in-effect literature discussed in Section 4 — the tax is deliberately neutral toward transactions that keep capital productively deployed and is triggered only by conversion into liquid, consumable wealth.

What remains open: "materially significant" and "illiquid" both require bright-line thresholds — a minimum ownership percentage and a minimum holding period in the new enterprise — that will inevitably sit close to some genuine edge cases; a rollover into a large, controlling stake that is nonetheless economically similar to holding a diversified portfolio is a boundary this mechanism does not fully resolve.

5.3 Constitutional Proportionality — Building In the 2014 Ruling's Requirements

Objection: an unconditional exemption while held, paired with a flat high tax on any later sale and no size limit, closely resembles the version of §§13a, 13b, and 19(1) ErbStG that Germany's Bundesverfassungsgericht (Federal Constitutional Court) declared unconstitutional in its judgment of 17 December 2014, for lacking any economic-needs test and for exempting smaller firms from the wage-preservation condition entirely. The Court affirmed the legislature's discretion to favor continued operation but found that specific implementation disproportionate, and gave the legislature until 30 June 2016 to redraft the rules — which produced the current thresholds, the Lohnsummenregelung, and the €26M/€90M Abschmelzmodell described in Section 3.1.

Design response — proportionality architecture

Build proportionality into the design from the outset, using the same four features the post-2016 German statute uses: (i) a size-indexed taper (mirroring the €26M-€90M Abschmelzmodell) so relief phases down rather than applying without limit to the largest estates; (ii) a wage-sum/job-preservation condition tied to eligibility, satisfied structurally by the mechanisms in Sections 5.1 and 5.4 rather than left as a separate afterthought; (iii) a hardship override (mirroring §28a ErbStG's Verschonungsbedarfsprüfung) for heirs who can demonstrate genuine inability to pay under ordinary rules; and (iv) a bounded retention period after which ordinary tax treatment resumes, rather than a permanent, unconditional exemption.

Grounding: this is not an original design choice so much as a direct transcription of the proportionality criteria the Bundesverfassungsgericht itself specified as the cure for the 2014 defect, applied prospectively rather than learned through a second round of litigation.

What remains open: proportionality architecture reduces constitutional risk but does not eliminate it; a graduated rate structure and an extraction-ledger threshold are novel enough that a future challenge on different grounds cannot be ruled out without a full constitutional-law analysis, which this paper does not attempt.

5.4 Capital Misallocation — The Going-Concern / Extraction Distinction

Objection: the lock-in literature discussed in Section 4 is unambiguous that realization-based taxation discourages sales generally, including economically efficient ones. A firm that should, on the merits, be sold to a better operator or wound down because its market has disappeared faces the same high tax as a thriving firm the heir simply wants to keep. A rate calibrated to stop opportunistic quick flips will also stop economically necessary exits. This compounds with a second, related problem: KfW Research's most recent Nachfolge-Monitoring (published January 2026) found that, for the first time on record, more German Mittelstand owners plan to close their business outright than plan to hand it to a successor — an estimated 569,000 planned closures against 545,000 planned handovers by the end of 2029 — and the ifo Institute has found that 42% of family businesses have no management successor lined up from within the family. A rule that simply penalizes any sale presumes a willing and competent heir where the data suggest close to half the time none exists.

Design response — the going-concern / extraction distinction

Split every disposal into two categories based on economic substance rather than legal form. A Going-Concern Transfer (GCT) is a sale to a buyer who contractually commits — with a claw-back bond — to continue operating the enterprise and to retain a specified share of its workforce (e.g., at least 80%) for a minimum period (e.g., three years). A GCT is taxed at a graduated moderate rate, illustratively 15% where job retention exceeds 80% and up to 30% between 50-79%, roughly comparable to ordinary capital gains treatment. A true Extraction Event — a liquidation, asset-stripping sale, or wind-down with no continuation commitment — is taxed at the high rate, illustratively 90%. This decouples continuity of family ownership from continuity of the enterprise: an heir who cannot or does not wish to run the business can sell it to a capable operator at a moderate tax rate, and the business and its jobs continue, which serves the policy's actual goal better than forcing the heir either to run an enterprise they are not equipped for or to accept a punitive tax to exit.

Grounding: this formalizes a distinction already implicit in the purpose clause of Germany's own business-relief statute, which was explicitly designed "to ensure their continued existence and to preserve jobs" (Bundesverfassungsgericht, 2014) — the mechanism extends that logic to the point of sale rather than stopping at the point of inheritance.

What remains open: job-retention commitments require monitoring and a bonding or claw-back enforcement mechanism, which is an administrative cost a flat rule would not have. A determined buyer could also retain jobs nominally for the covenant period and restructure immediately after it lapses — a three-year window narrows but does not eliminate this.

Figure 5. Germany's Mittelstand succession pressure by source (KfW Research, IfM Bonn). The rightmost bar — 569,000 planned closures with no succession plan by end-2029 — is the first time KfW's tracking has recorded more planned closures than planned handovers, which is the empirical basis for Section 5.4 and 5.5.

5.5 Successor Incapacity — Certified Interim Stewardship

Objection: even with the going-concern sale option in Section 5.4, an heir who is not yet ready to run the business and has not yet found a buyer should not be forced into an immediate, high-tax decision the moment the business passes to them.

Design response — certified interim stewardship

An heir may appoint a certified professional interim manager or trustee for up to a defined period (e.g., three years) without breaking eligibility for deferral, giving time to identify a family successor, arrange a management buy-in/buy-out, or locate a going-concern buyer under Section 5.4. This formalizes, as a matter of tax eligibility, a solution path that is already emerging informally in the German succession-advisory market.

Grounding: interim professional stewardship of family enterprises pending a permanent succession solution is an established practice in German Mittelstand succession advisory (the KERN network and similar firms) and is the operating model of the growing search-fund and management-buy-in sector documented in current market reporting on the German succession gap.

What remains open: a fixed window still eventually forces a decision, and three years may be too short for some transitions and an unnecessary grace period that invites gaming in others; the period should plausibly be set by enterprise size or complexity rather than as a single fixed number.

5.6 Revenue Volatility — A Two-Tier Revenue Structure

Objection: because tax is collected only at an unpredictable future extraction event rather than at the predictable moment of death, revenue under a pure hold-tax-free/extract-and-pay design becomes lumpy and pro-cyclical. Heirs are least likely to extract value during a recession, when asset prices are depressed, and most likely to do so in a boom — meaning revenue would tend to arrive exactly when the state least needs counter-cyclical support and disappear exactly when it most does.

Design response — a two-tier revenue structure

Replace a pure zero-tax-while-held design with a two-tier structure: a modest, predictable baseline levy at the time of transfer (illustratively 10%, well below current effective rates on large estates in either country), payable in installments over several years to preserve liquidity for the heir, plus the going-concern or extraction tax from Section 5.4 when a realization event eventually occurs. The baseline levy is creditable against the eventual tax, so total lifetime burden does not simply stack the two on top of each other.

Grounding: this follows the general public-finance principle — visible in tax-smoothing and installment-payment provisions that already exist in both the German and US systems for illiquid estates — that a predictable minimum base is preferable to an all-or-nothing bet on a single future event.

What remains open: a baseline levy reintroduces, at a smaller scale, exactly the liquidity problem this proposal otherwise tries to eliminate; 10% is a judgment call with no unique correct value, and setting it too high recreates the forced-liquidation problem the whole proposal exists to solve.

5.7 Regressivity — The Universal Opportunity Endowment

Objection: this proposal is framed explicitly around "equal chances," but the mechanism as stated in Section 2 is available only to heirs who inherit an operating business or comparable productive asset in the first place. An heir who inherits cash, a diversified portfolio, or nothing at all gets no equivalent benefit. In practice, a rule like this overwhelmingly benefits families who already own concentrated productive capital — the group least in need of an equal-chances subsidy — while doing nothing for the larger number of heirs who inherit small or liquid estates and continue to pay ordinary inheritance tax on them. Paired with a flatter income tax on labor income (Section 7), the combined package risks shifting relative burden away from capital transfer and toward whatever tax base remains to fund the state, which is regressive by the standard distributional definition of that term — the opposite of the framing offered for it.

Design response — the Universal Opportunity Endowment

Dedicate a defined share of the revenue raised under Section 5.6 (baseline levy plus extraction/going-concern tax) to a Universal Opportunity Endowment: a modest, one-time capital grant paid to every citizen at adulthood, regardless of what — if anything — they personally inherit. This directly extends the policy's equal-chances goal to the majority of heirs the core mechanism does not reach, funded specifically by the tax the proposal already imposes on those who inherit concentrated productive wealth.

Grounding: this mechanism follows Tony Atkinson's proposal for a universal capital endowment of roughly £5,000-£10,000 per young adult funded by a lifetime capital-receipts tax, and Bruce Ackerman and Anne Alstott's 1999 stakeholder-grant proposal, which argued explicitly that every citizen has a claim on the wealth accumulated by preceding generations and proposed funding a universal grant from taxes on concentrated wealth transfer. Grafting that mechanism onto this proposal's revenue base directly connects the paper's "equal chances" framing to an existing, peer-debated redistributive design rather than leaving it as an unexamined assertion.

What remains open: the endowment's size is mechanically capped by how much Section 5.6's structure actually raises once Sections 5.1, 5.2, and 5.4 have all reduced the effective rate collected on any given estate relative to a naive reading of a 90%-of-everything baseline — so the endowment is likely to be a meaningful but not transformative sum per person, and its size should be stated honestly to the public as bounded by realized receipts, not promised as a fixed amount in advance.

Figure 7. Illustrative benefit distribution by heir type: a mechanism limited to Section 2 alone (red) delivers its benefit only to heirs of operating businesses; adding the Section 5.7 endowment (teal) preserves that benefit and extends a smaller, funded benefit to all heirs.

5.8 Valuation Gaming — Self-Assessed Valuation with Market Discipline

Objection: any bright-line rule this valuable to be on the correct side of will attract valuation gaming. If the extraction tax is calculated net of basis, there is a strong incentive to inflate the claimed basis at the time of inheritance, and the incentive to manipulate the Section 5.1 ledger threshold grows with the size of the rate differential the valuation controls.

Design response — self-assessed valuation with market discipline

At inheritance, the heir self-declares the enterprise's value, which becomes both the cost basis for later tax calculations and the reference point for the Section 5.1 ledger threshold. An independent certified valuation (using an established standard, e.g., Germany's IDW S1 or a comparable US appraisal methodology) is obtained within 12 months. Declaring too low is discouraged because it lowers the ledger threshold, triggering deemed realization sooner, and because a large negative variance from the certified valuation (illustratively, understatement of more than 40%) gives co-heirs, or a designated public fund, a time-limited right to acquire the heir's stake at the declared value plus a modest premium. Declaring too high raises the eventual tax-free ledger cushion but has no other benefit and increases the taxable base if the enterprise is later sold below the declared value.

Grounding: this is a moderated adaptation of the self-assessed-valuation-with-purchase-right logic — the Common Ownership Self-Assessed Tax (COST), sometimes called a Harberger tax — originating with Arnold Harberger and developed by Eric Posner and Glen Weyl in Radical Markets (2018), where a standing right for others to buy an asset at its self-declared price is used to discourage strategic under-declaration without relying solely on audits.

What remains open: a full Harberger-style unconditional buyout right is a poor fit for a family enterprise this policy is trying to keep intact — forcing a sale defeats the point — which is why this mechanism moderates the original COST design substantially, limiting the purchase right to large-variance cases and to co-heirs or a public fund rather than any bidder. Even moderated, this is the most novel and least battle-tested mechanism in this paper and would need careful piloting before being generalized; the Harberger/COST literature it draws on has faced serious, unresolved criticism, including concerns about complementary-asset investment distortions and, in its most literal common-ownership form, direct objections to compelled sale of personal property.

Table 1 assembles the mechanisms from Section 5 into a single reference structure, organized by the triggering event rather than by the objection each mechanism answers.

Table 1. Integrated statutory sketch: tax treatment by triggering event, referencing the section that develops each mechanism.

7. The Companion Income Tax Proposal

The second half of this proposal eases the marginal income tax rate to roughly 20% around €100,000, a separate policy lever aimed at a related goal: freeing up capital for entrepreneurship among people who are earning, not just inheriting. It is useful to see it against the current German tariff.

Germany's 2026 tariff (§32a EStG) is a continuous, formula-based progressive schedule, not fixed brackets. Income up to the Grundfreibetrag (€12,348 in 2026) is untaxed. Marginal rates then rise smoothly from 14% to the Spitzensteuersatz of 42%, which currently begins at €69,879 for single filers — meaning a taxpayer earning €100,000 today already faces a marginal rate of 42% on income above that threshold, roughly double the rate proposed here. A further "rich tax" (Reichensteuer) of 45% applies above €277,826.

Figure 8. Germany's actual 2026 effective average income-tax rate (solid) versus an illustrative eased path in which the marginal rate above €100,000 is capped near 20% (dashed). Below €100,000 the two lines are identical by construction.

7.1 What the evidence says about this kind of cut

The economic case for lower marginal rates encouraging entrepreneurship rests on the elasticity of taxable income (ETI) literature. Empirical estimates of ETI vary substantially by country, income level, and time period, and the consensus among public-finance economists is that the elasticity for ordinary wage income is modest, while it is meaningfully larger for the self-employed, business owners, and high earners with more latitude over the form and timing of their compensation — precisely the population this proposal targets. This lends the idea genuine support: a rate cut concentrated on earners near €100,000, many of whom are in a position to become or remain entrepreneurs, is more likely to produce a real behavioral response than an across-the-board cut of the same fiscal size.

The weak point is fiscal, not behavioral. Halving the marginal rate on a wide income band is expensive, and Laffer-curve-style self-financing is empirically the exception rather than the rule outside of very high, near-confiscatory starting rates. At Germany's current 42%, there is no serious body of evidence suggesting a cut to 20% would be revenue-neutral; it needs an explicit financing plan rather than an assumption.

7.2 A fiscal trigger, not a promise

To finance the cut credibly, its phase-in is indexed formally to a rolling multi-year average of actual receipts from the structure in Section 5.6 (baseline levy plus extraction/going-concern tax), via a stabilization corridor: if receipts run below the corridor's floor, the phase-in pauses or slows; if receipts run at or above projection, it proceeds on schedule or accelerates. This is an automatic fiscal rule in the spirit of Germany's own constitutional debt brake (Schuldenbremse), which similarly ties a policy lever to a measured fiscal variable rather than a fixed political timetable. Such a trigger only works if it is honored during a downturn, which is exactly when the political pressure to keep a popular tax cut running regardless of the corridor will be highest; institutional credibility, not just the formula, does the real work here.

8. Fiscal and Distributional Illustration

Figure 9 restates the German business-relief comparison from Section 3 for reference — the baseline levy proposed in Section 5.6 sits between the two, closer to the existing 15% "effective rate under full relief" bar than either the near-zero or the 90% cases.

Figure 9. For reference: existing German business relief, against which the Section 5.6 baseline levy (~10%) and Section 5.4 going-concern rates (15-30%) should be read.

On the income-tax side, the fiscal cost of easing the marginal rate to roughly 20% above €100,000 (versus today's 42%) is substantial and grows with the number of taxpayers in that band. Table 1 and the mechanisms in Section 5 make clear that the effective revenue collected under the extraction-tax leg will be considerably smaller than a naive reading of a 90% headline rate would suggest, once the baseline levy, the going-concern carve-out, and the productive rollover exception are all accounted for — which is precisely why Section 7.2 ties the income-tax phase-in to realized receipts rather than to the headline rate.

9. Limitations and Open Questions

Stated plainly, this proposal does not resolve every difficulty it raises.

• Administrative complexity is substantial. A single zero-tax/high-tax switch would be trivial to explain and administer; a system with an extraction ledger, a job-retention bond, a self-assessed valuation with a variance-triggered buyout right, and a revenue-indexed fiscal trigger is not. Each mechanism that closes a loophole in Section 5 adds a compliance and enforcement burden that a simpler, more exploitable rule would not have had.
• The self-assessed valuation mechanism in Section 5.8 is the least tested idea in this paper. The Harberger/COST literature it draws on has faced serious, unresolved criticism, and this paper's moderated version has not itself been piloted or modeled quantitatively.
• The Universal Opportunity Endowment in Section 5.7 is bounded by how much the underlying tax actually raises once the other mechanisms have reduced the effective rate collected; it should not be oversold as a large per-person sum without first modeling realistic receipts, which this paper — lacking access to firm-level estate data in either jurisdiction — does not attempt.
• None of the mechanisms in Section 5 has been tested against a full constitutional-law or EU state-aid analysis; Section 5.3 reduces the specific risk the 2014 German ruling identified but is not a guarantee against a different challenge.
• The core empirical claim underlying the whole proposal — that a meaningful share of heirs will keep businesses running longer under this regime than under ordinary inheritance tax, and that the jobs preserved as a result exceed the efficiency cost of the transactions the policy discourages (Section 5.4) — remains a theoretical prediction grounded in the lock-in-effect literature's general finding, not a measurement specific to this policy, because no jurisdiction has implemented this exact design.

10. Conclusion

The proposal in this paper starts from a genuinely respectable intuition, one with real legal precedent in Germany and a partial analogue in US stepped-up basis: taxing the act of extracting value rather than the act of inheriting can discourage unnecessary breakup of productive, job-preserving enterprises. Section 4 shows that intuition survives contact with the relevant economic literature. A version of the mechanism stated too simply — an unconditional exemption while held, paired with a flat 90% tax on any later sale — would not survive contact with the objections in Section 5: it would be vulnerable to debt-extraction and corporate-wrapper avoidance, would resemble a design Germany's Federal Constitutional Court has already found disproportionate once, would risk entrenching economically unviable firms precisely because roughly half of German family-business heirs currently lack a ready or willing successor, would produce unpredictable revenue, and — despite its egalitarian framing — would concentrate its benefit on families who already hold productive capital while doing nothing for heirs of liquid wealth, which is regressive relative to the policy's own stated aim.

The design developed across Sections 5 and 6 — graduated by realization type, ledgered against debt extraction, bounded by size and time, disciplined by a market-based valuation mechanism, smoothed for revenue, and paired with a universal endowment that extends the policy's own equal-opportunity language to every citizen rather than only to those who happen to inherit a company — addresses each objection with a specific, literature-grounded mechanism rather than leaving it unanswered. That design is unmistakably more complex than the one-line version of the idea. Complexity is the price of closing the loopholes the simpler version would have left open, and Section 9 states plainly which of the nine mechanisms are best regarded as settled design and which would need piloting, not just drafting, before becoming law.
