The Compute Commons Compact

Doctrine in one sentence

Preserve mass economic agency by socialising the rent from AI-driven unit-cost advantages through observable infrastructure and data levies, distributing returns as universal services and capital dividends, while insulating households from rent capture.

Executive summary

The Unit Cost Dominance thesis identifies a structural risk: if AI plus verification makes broad cognitive work cheaper per unit than human-only production, the wage-demand circuit that underpins postwar prosperity can fray without mass unemployment ever arriving. This memorandum proposes a policy package that does not require measuring AI share in workflows, does not depend on global coordination, and remains useful if the thesis proves overstated. It builds on observable bases — compute capacity, data-centre energy draw, platform revenue, capital gains — that tax authorities can already administer. It assigns clear actions to the United Kingdom Parliament, the European Union institutions, and EU member states within their existing competences. It funds a floor of economic agency through universal basic services and a compute dividend, while blocking rent absorption through land-value capture and platform-fee caps. It phases implementation over two years, five years, and contingent triggers. It identifies the fiscal arithmetic, the political coalition, the durability safeguards, and the falsifiability conditions. The central trade-off is between the speed of a new revenue base and the certainty of its yield; the package accepts a transition period funded by borrowing against future levy streams, scored by the Office for Budget Responsibility and the European Fiscal Board.

The policy package

The package contains seven planks. Each attaches to an observable base, survives adoption, and has bounded regret.

Plank 1: Compute Capacity Levy. A per-rack-unit or per-megawatt levy on data-centre capacity above a de-minimis threshold, collected from the facility operator. The base is physical, auditable by energy regulators, and hard to offshore without latency penalty. Revenue flows to a Compute Commons Fund at UK or EU level. The levy rate is set low initially and rises on a published schedule contingent on adoption indicators.

Plank 2: Platform Revenue Share. A 1.5 percent levy on gross revenue of designated large digital platforms (turnover above €750 million, UK equivalent) derived from algorithmic curation, targeted advertising, or marketplace fees. The base is declared in existing country-by-country reporting. Revenue is split between the Compute Commons Fund and a Universal Basic Services expansion.

Plank 3: Capital Income Recapture. Alignment of capital-gains and dividend rates with earned-income rates above an annual allowance, plus a 0.5 percent annual buyback levy on net share repurchases by listed firms. The base is self-assessed through existing tax returns. Revenue funds the Compute Dividend.

Plank 4: Public Compute Equity Dividend. The UK National Wealth Fund and a new EU Sovereign Compute Vehicle take equity or convertible stakes in every sovereign-compute and gigafactory project they finance. Distributable returns are paid as a quarterly Compute Dividend to every legal resident adult, administered through the tax-benefit system. The dividend is not means-tested and does not affect Universal Credit or national equivalents.

Plank 5: Universal Basic Services Expansion. A statutory floor of in-kind entitlements: social-housing access at local-housing-allowance rent caps, zero-carbon home-energy allowance, local public-transport season tickets, and a digital-access bundle (broadband, device voucher, cloud storage). Funding comes from Planks 1, 2, and 3. Delivery remains with local authorities and member-state agencies.

Plank 6: Portable Transition Accounts. Every worker accrues a portable credit (£500 or €600 per year of employment, pro-rated) funded by a 0.3 percent employer payroll levy on earnings above the upper earnings limit. Credits fund retraining, care leave, or business start-up costs. Accounts are portable across employers and borders within the UK-EU mobility framework.

Plank 7: Anti-Rent Absorption Shield. A mandatory land-value uplift capture on planning permissions (50 percent of uplift value), a residential-rent-stabilisation index linked to local earnings, and a cap on platform take-rates for essential digital services (15 percent for marketplace, 10 percent for payment). Enforcement through existing valuation offices and competition authorities.

United Kingdom: first 24 months

Months 1 to 3. Treasury publishes a Compute Capacity Levy consultation with three rate bands tied to rack-unit density and power-usage effectiveness. DSIT commissions the National Grid and Ofgem to audit data-centre capacity within six months. Legislation introduced in Finance Bill for Platform Revenue Share (mirroring Digital Services Tax mechanics but broader base) and Capital Income Recapture (rate alignment above £50,000 annual gains, buyback levy). National Wealth Fund mandate amended to require equity or convertibles in all sovereign-compute projects; first dividend payment scheduled for quarter four of year two.

Months 4 to 9. Compute Capacity Levy enacted at introductory rate (£15 per rack-unit per month, £2,000 per megawatt per month). Platform Revenue Share takes effect. Capital Income Recapture applies to disposals after Royal Assent. Universal Basic Services Expansion begins with social-housing rent-cap enforcement and energy-allowance pilot in three combined authorities. Portable Transition Accounts legislation introduced; HMRC builds ledger on existing PAYE infrastructure.

Months 10 to 18. First Compute Dividend paid (estimated £40 per adult per quarter, rising). Land-value uplift capture enacted through Planning Reform Bill. Rent-stabilisation index published by ONS. Platform take-rate caps enforced by CMA. Transition Accounts go live for new hires; existing workers opt in.

Months 19 to 24. Review point. OBR scores yield against forecast. If Compute Capacity Levy yield exceeds 1.2 times forecast, rate escalator accelerates. If yield falls short, Platform Revenue Share rate rises by 0.25 percentage points. Universal Basic Services Expansion extended to digital-access bundle nationwide.

European Union and member states: first 24 months

Months 1 to 3. Commission proposes a Compute Capacity Directive under Article 114 TFEU (internal market) setting minimum levy base definitions (rack-unit, megawatt, PUE) and a floor rate (€10 per rack-unit per month, €1,500 per megawatt per month). Member states may set higher rates. Platform Revenue Share proposed as a new own resource under Article 311 TFEU (requires unanimity; fallback: enhanced cooperation among willing member states). Capital Income Recapture left to member states with a coordination recommendation (minimum 0.5 percent buyback levy, rate alignment above €60,000 gains).

Months 4 to 9. EU Sovereign Compute Vehicle established under the European Investment Bank, capitalised by €20 billion from the €200 billion AI investment envelope (gigafactory equity). Mandate: equity or convertibles in all supported projects. Compute Dividend regulation adopted: quarterly payment to all legal residents in participating member states, administered via national tax authorities. Universal Basic Services framework directive adopted (housing, energy, transport, digital) setting minimum standards; funding from national budgets supplemented by Platform Revenue Share own resource.

Months 10 to 18. Compute Capacity Directive transposed. Platform Revenue Share own resource enters EU budget (if unanimity achieved) or enhanced-cooperation budget. First Compute Dividend paid in participating states (estimated €45 per adult per quarter). Portable Transition Accounts regulation adopted under Article 153 TFEU (social policy) for cross-border portability. Anti-Rent Absorption Shield: Commission issues recommendation on land-value capture and rent-stabilisation; member states implement via national law.

Months 19 to 24. Review by European Fiscal Board and European Court of Auditors. If own-resource yield is insufficient, Commission proposes rate adjustment. Non-participating member states may join enhanced cooperation. Universal Basic Services minimum standards enforced through European Semester.

Years 3 to 5 and dormant triggers

Years 3 to 5 (steady state). Compute Capacity Levy rates rise on published escalator (5 percent per year real) unless adoption indicators (ONS AI-use share, Eurostat digital-intensity index) show deceleration for two consecutive years. Platform Revenue Share rate adjusts to maintain 0.5 percent of GDP yield. Capital Income Recapture rates reviewed against effective average tax rate on labour. Compute Dividend target: 2 percent of median equivalised disposable income. Universal Basic Services floor extended to childcare and long-term care access. Portable Transition Accounts credit rises with productivity growth.

Dormant triggers (scale up). If ONS or Eurostat reports AI-related headcount reduction exceeding 3 percent of employment in any two consecutive quarters, or if median real wage growth falls below zero for four quarters while productivity rises, the following activate automatically: Compute Capacity Levy rate doubles; Platform Revenue Share rises by 1 percentage point; Compute Dividend frequency moves to monthly; Universal Basic Services floor expands to food-voucher supplement for households below 60 percent median income; employer payroll levy for Transition Accounts rises to 0.6 percent.

Dormant triggers (scale down). If AI-adoption indicators plateau for three years and wage growth resumes above productivity for two years, levy escalators pause. Compute Dividend reverts to quarterly. Platform Revenue Share rate falls by 0.25 percentage points per year to a floor of 0.5 percent.

Review points. Annual report to Parliament and European Parliament by independent Compute Commons Commission (UK) and European Fiscal Board (EU). Five-year sunset clause on escalators unless renewed by supermajority (two-thirds in Commons, reinforced qualified majority in Council).

Funding and fiscal arithmetic

UK arithmetic (illustrative, requires OBR scoring). Compute Capacity Levy: 1.2 million rack-units × £180 per year = £216 million; 3,500 MW × £24,000 per year = £84 million. Year-one yield ~£300 million, rising to ~£1.2 billion by year five with escalator and capacity growth. Platform Revenue Share: UK large-platform revenue ~£45 billion × 1.5 percent = £675 million. Capital Income Recapture: Rate alignment yields ~£3.5 billion (HMRC ready-reckoner). Buyback levy: £50 billion buybacks × 0.5 percent = £250 million. Total recurring year-five yield ~£5.6 billion. Compute Dividend: 54 million adults × £160 per year = £8.6 billion. Gap ~£3 billion. Transition funding: National Wealth Fund equity returns (conservative 4 percent on £10 billion deployed = £400 million), borrowing against levy stream (gilt issuance within fiscal rules), and Universal Credit savings from in-kind services substitution (estimated £1.5 billion). Residual gap acknowledged; requires either higher Platform Revenue Share (to 2 percent) or broader Capital Income Recapture. OBR must score before enactment.

EU arithmetic (illustrative, requires European Fiscal Board scoring). Compute Capacity Levy floor: EU data-centre capacity ~10 million rack-units, 25,000 MW. Floor yield ~€1.3 billion. Member-state top-ups add ~€2 billion. Platform Revenue Share own resource: EU large-platform revenue ~€180 billion × 1.5 percent = €2.7 billion. Capital Income Recapture: Member-state yield ~€15 billion (aggregate). Sovereign Compute Vehicle: €20 billion equity, 5 percent distributable return = €1 billion. Total recurring ~€21 billion. Compute Dividend: 360 million adults × €180 = €64.8 billion. Gap €44 billion. Universal Basic Services floor funded nationally; Platform Revenue Share own resource covers EU-level coordination (€5 billion). Gap acknowledged: Compute Dividend at target scale requires either higher Platform Revenue Share (to 3 percent), broader compute levy base (including edge devices), or member-state top-ups. The package proposes a phased dividend: €90 per year years 1 to 2, €180 years 3 to 5, full target only if yield triggers met. European Fiscal Board must score.

Missing arithmetic. Precise data-centre capacity registers do not yet exist in UK or EU. Platform revenue attribution by jurisdiction relies on country-by-country reporting not yet public. Capital Income Recapture behavioural responses uncertain. National Wealth Fund and Sovereign Compute Vehicle equity returns are speculative. These must be modelled before enactment.

Political coalition and public case

Coalition. UK: Labour backbenchers concerned about cost of living, Liberal Democrats (universal basic services), SNP (compute dividend), Green Party (land-value capture), Confederation of British Industry (portable transition accounts as skills solution), Trades Union Congress (wage insurance). Losers: large digital platforms (Platform Revenue Share), listed firms with heavy buybacks (buyback levy), data-centre operators (Compute Capacity Levy), private landlords (rent stabilisation). Compensation: platforms get certainty and single levy replacing Digital Services Tax; data-centre operators get streamlined planning for renewable co-location; landlords get planning uplift on the 50 percent they retain. EU: Socialists and Democrats, Renew, Greens/EFA, Left (enhanced cooperation core). Losers: low-tax member states (Ireland, Luxembourg) on Platform Revenue Share own resource; large platforms; financial centres on buyback levy. Compensation: enhanced cooperation allows willing states to proceed; low-tax states retain corporate-tax sovereignty; Sovereign Compute Vehicle directs gigafactory investment to their regions.

Public case (ordinary language). "AI is making it cheaper for machines to do office work. That means the wages that pay for homes, bills, and groceries could shrink even while the economy grows. This plan taxes the computer farms and the big platforms that profit from the change, and uses the money to guarantee everyone a decent home, warm heating, free travel, and a quarterly dividend. It also gives you a portable pot for retraining or time off. Your rent won't eat the dividend because we cap rent rises and capture land-value windfalls. If the AI boom fades, the taxes pause. If it accelerates, the dividend grows."

Sequencing. Year one: visible wins (rent caps, energy allowance, first dividend). Year two: Transition Accounts live, Platform Revenue Share visible on receipts. Year three: dividend scales, Universal Basic Services floor complete. Narrative: "fair share from the machine age" not "robot tax".

Durability and anti-capture design

Capture risks and mitigations. Legislative capture: Levy rates set by statutory escalator tied to published indicators, not annual Budget discretion. Compute Commons Commission (UK) and European Fiscal Board (EU) are independent, with appointments requiring cross-party supermajority. Administrative capture: Dividend paid via tax-benefit system (HMRC, national equivalents) not new agency. Universal Basic Services delivered by existing local authorities. Financial raid: Compute Commons Fund and Sovereign Compute Vehicle capital locked by statute; only distributable returns may be spent. Borrowing against future levy streams requires independent scoring and parliamentary supermajority. Avoidance: Compute Capacity Levy on physical rack-units and megawatts — hard to hide. Platform Revenue Share on gross revenue from country-by-country reporting — transfer-pricing rules apply. Capital Income Recapture on realised gains and buybacks — existing anti-avoidance. Offshoring: Data-centre latency requirements keep capacity near users. Platform Revenue Share applies to revenue from UK/EU users regardless of corporate domicile. Hostile future government: Five-year sunset on escalators forces renewal debate. Dividend universal and visible — politically costly to cut. Universal Basic Services statutory — requires primary legislation to repeal. Concentration of power: Compute Commons Commission has no policy-making role beyond reporting. Sovereign Compute Vehicle governed by independent board with worker and civil-society seats.

Legal and institutional obstacles

UK. Compute Capacity Levy: requires primary legislation (Finance Bill). No devolution conflict (reserved). Platform Revenue Share: primary legislation. Risk of double-taxation treaty challenges; mitigate by crediting against Digital Services Tax. Capital Income Recapture: primary legislation. Rate alignment may face Human Rights Protocol 1 Article 1 challenge (peaceful enjoyment of possessions); defend as proportionate fiscal measure. National Wealth Fund mandate change: secondary legislation under existing Act. Universal Basic Services: housing and energy devolved in Scotland; requires legislative consent motions. Land-value uplift capture: Planning Reform Bill primary legislation. Rent stabilisation: Renters' Reform Bill primary legislation; devolved in Scotland. Platform take-rate caps: Digital Markets, Competition and Consumers Act powers; CMA enforcement.

EU. Compute Capacity Directive: Article 114 TFEU (internal market) — qualified majority, European Parliament co-decision. Legal base contested if deemed fiscal; fallback Article 192 TFEU (environment) for energy-component. Platform Revenue Share own resource: Article 311 TFEU — unanimity required. If blocked, enhanced cooperation under Article 20 TEU (minimum nine member states). Capital Income Recapture: member-state competence; coordination recommendation non-binding. Sovereign Compute Vehicle: EIB statute amendment (unanimity) or new regulation under Article 173 TFEU (industrial policy) — qualified majority. Compute Dividend regulation: Article 153 TFEU (social policy) — qualified majority, but may require unanimity if deemed to affect social security. Fallback: national dividends coordinated by recommendation. Universal Basic Services framework directive: Article 153 TFEU — qualified majority. Minimum standards only. Portable Transition Accounts regulation: Article 153 TFEU — qualified majority. Anti-Rent Absorption Shield: recommendations only; member-state implementation.

Cross-border. UK-EU mobility framework for Transition Accounts portability requires negotiated agreement (Trade and Cooperation Agreement specialist committee). Data-centre levy coordination avoids double taxation via mutual recognition of capacity audits.

Failure modes, review and exit rules

Failure mode 1: Levy yield collapses due to avoidance. Indicator: Compute Capacity Levy yield falls 20 percent below forecast for two consecutive years while data-centre capacity grows. Response: Shift base to electricity consumption at meter (Ofgem/ACER verified). Platform Revenue Share rate increases by 0.5 percentage points. Review at month 30.

Failure mode 2: Dividend absorbed by rent and energy costs. Indicator: Median rent-to-income ratio rises above 35 percent in any region; energy arrears rise 15 percent year-on-year. Response: Rent-stabilisation index tightens to CPI minus 1 percent. Land-value uplift capture rises to 60 percent. Energy allowance increases by 20 percent. Review at month 18 and annually.

Failure mode 3: Political backlash triggers repeal. Indicator: Government loses confidence vote on package; or European Council rejects own resource. Response: Package designed as modular. Compute Dividend and Universal Basic Services can survive as national policies. Platform Revenue Share reverts to Digital Services Tax. Compute Capacity Levy becomes national. Transition Accounts remain. No cliff edge.

Failure mode 4: Thesis substantially wrong (AI adoption plateaus, wages rise). Indicator: ONS AI-use share flat for three years; median real wage growth exceeds productivity for two years; AI-related headcount reduction below 1 percent. Response: Escalators pause. Dividend reverts to quarterly at year-two level. Platform Revenue Share falls to 0.5 percent. Compute Capacity Levy holds at year-three rate. Universal Basic Services floor remains (bounded regret: in-kind services have independent merit). Five-year review decides on full sunset.

Review schedule. Month 12: Implementation audit (NAO, ECA). Month 24: First yield review (OBR, European Fiscal Board). Year 3: Distributional analysis (IFS, Eurostat). Year 5: Full impact assessment (Compute Commons Commission, European Fiscal Board). Every 5 years thereafter: Sunset renewal vote.

Exit rules. Any plank may be scaled down by simple majority if its trigger condition is met for two consecutive review periods. Full package sunset requires supermajority (two-thirds Commons, reinforced qualified majority Council) after year 10. Compute Dividend and Universal Basic Services have separate sunset clauses requiring same supermajority.

Feasibility table

What is genuinely new here

1. Compute Capacity Levy on physical rack-units and megawatts — not a robot tax, not an AI-model tax, but a levy on the observable infrastructure that enables unit-cost dominance. Hard to avoid, auditable by energy regulators, latency-tethered.

2. Public Compute Equity Dividend — sovereign wealth funds (National Wealth Fund, Sovereign Compute Vehicle) take equity in the compute they finance, distributing returns as a universal dividend. Turns industrial policy into direct household income without means-testing.

3. Anti-Rent Absorption Shield as integral, not afterthought — land-value uplift capture, rent-stabilisation index, and platform take-rate caps are funded planks, not aspirations. They protect the dividend and services from being captured by scarce-position holders.

4. Dormant triggers tied to adoption indicators, not unemployment — the package scales up when AI-related headcount reduction exceeds 3 percent or wages decouple from productivity, not when unemployment spikes. Scales down when wage growth resumes.

5. Modular UK-EU architecture with enhanced-cooperation fallback — does not wait for EU unanimity. Willing member states proceed; UK mirrors. Portable Transition Accounts bridge the border.

6. Bounded-regret accounting — every plank has independent merit (efficient compute, fairer capital tax, housing stability, skills investment). If the thesis is wrong, the package leaves a better tax base, a sovereign compute portfolio, a stronger housing floor, and a portable skills system.

Bottom line

The Compute Commons Compact accepts the Unit Cost Dominance thesis as a serious contingency. It does not bet the fiscal framework on it. It builds seven planks on observable bases that governments can administer today. It assigns clear actions to the UK Parliament, the EU institutions, and member states within their legal powers. It funds a floor of economic agency — universal basic services and a compute dividend — while blocking rent absorption. It phases implementation, sets dormant triggers for scaling up or down, and defines exit rules. The fiscal arithmetic shows a gap at full dividend scale; this is acknowledged, not hidden. The gap closes either through higher platform levy rates, broader compute bases, or member-state top-ups, all decided at review points with independent scoring. The political coalition is plausible: workers, renters, small businesses, and regions left behind by the current model. The losers are concentrated and identifiable; compensation is offered. The package has bounded regret: if AI adoption plateaus, the UK and EU gain a fairer capital tax, a sovereign compute portfolio, a stronger housing floor, and a portable skills system. If the thesis proves right, the institutions to share the gains already exist.
