Status: Comprehensive policy package with agricultural property exemption from wealth tax


Executive Summary

A revenue-neutral transformation of the UK tax system, abolishing £314bn in taxes on work and replacing them with £328bn in new revenue focused on wealth, pollution, and land. The reform simplifies the system from 11 separate taxes to 6 core taxes (plus 4 supplementary revenue measures), leaves 75-80% of households better off, creates 800k-1.1m jobs, and achieves a 22% emissions reduction by 2030.

Core changes:

  • Simplifies from 11 taxes to 6 core taxes
  • Leaves 75-80% of households better off
  • Projects 800,000-1.1m job creation
  • Targets 22% emissions reduction by 2030
  • Generates £34.35bn surplus for green investment

Core principle: Tax wealth and pollution, not work.


Part 1: What Gets Abolished

Total Abolished: £314.5bn

Tax Being Scrapped Current Revenue When
Employee National Insurance £95bn April 2026 (Year 1)
Employer National Insurance £105.6bn April 2027 (Year 2)
Council Tax £50.2bn April 2028 (Year 3)
Business Rates £26bn April 2027 (Year 2)
Fuel Duty £24bn April 2026 (Year 1)
Vehicle Excise Duty £7bn April 2027 (Year 2)
Inheritance Tax £7.5bn April 2026 (Year 1)
Separate CGT/Dividend systems (merged) April 2026 (Year 1)

Why abolish these? They penalise work, distort economic decisions, and rely on outdated systems (council tax still uses 1991 valuations).


Part 2: The New Tax System

Total New Revenue: £649.65bn

This includes £230bn current income tax being replaced by £248bn reformed income tax, and £70bn current corporation tax being replaced by £60bn reduced corporation tax. The net additional revenue (after accounting for replacements) is £349.65bn, which more than covers the £314.5bn being abolished, leaving a £34.35bn surplus.


1. Reformed Income Tax: £248bn

Key change: ALL income treated identically—no separate systems for employment, dividends, capital gains, interest, or self-employment.

New rates:

  • £0–£25,000: 0% (personal allowance doubled from £12,570)
  • £25,001–£100,000: 25%
  • £100,001–£250,000: 42%
  • Over £250,000: 47%

What counts as income: Employment, self-employment, dividends, capital gains, interest, rental income, pension drawdowns—all taxed identically.

Thresholds: Inflation-indexed annually using September CPI.

What's abolished:

  • Separate Capital Gains Tax (currently 18%/24% on property, 10%/20% on assets)
  • Separate dividend tax (8.75%/33.75%/39.35%)
  • Inheritance Tax (wealth already taxed annually)

Pension tax relief: Maintained at marginal rates (25%/42%/47%) for simplicity.

Revenue: £248bn (up from £230bn as investment income now taxed at regular rates)


2. Progressive Wealth Tax: £84.75bn

What's taxed: Net wealth above £100,000 (excluding pensions)

  • Property equity (value minus mortgage)
  • Savings and investments
  • Business assets (for passive owners)
  • Valuables, art, collectables

What's exempt:

  • Pensions (to encourage retirement saving)
  • Agricultural land and buildings used for farming (maintains current IHT Agricultural Property Relief treatment)

Progressive bands:

Net Wealth Annual Rate Who This Affects
Under £100,000 0% Bottom 75%
£100,000–£500,000 0.8% Upper-middle class
£500,000–£1m 1.0% Affluent
£1m–£3m 1.5% Wealthy
£3m–£10m 2.5% Very wealthy
£10m–£25m 4.0% Ultra-wealthy
Over £25m 5.3% Top 0.01%

Key safeguards:

  • Exit tax: 25% on wealth over £1m for tax emigration (separate £3bn revenue source)
  • Asset-rich-income-poor relief: defer payment against property until sale/death if wealth >£500k but income <£25k
  • Self-declaration with severe penalties for undervaluation (200% + prosecution)
  • Professional valuations required every 5 years for wealth over £2m
  • Annual wealth statements required for wealth >£500k
  • Thresholds inflation-indexed annually

Performance-Based Deferral Mechanism:

The wealth tax recognises that not all assets behave the same way. While the tax applies to the stock of wealth, its effective pressure adjusts based on whether assets are actually growing.

Core principle: Tax the stock, but allow timing flexibility for genuinely stagnant assets.

How it works:

  • Assets appreciating <2% annually (inflation-adjusted) qualify for partial deferral
  • Calculation: If asset grew 1% in real terms, only 50% of wealth tax is due immediately
  • Remaining 50% deferred and accumulated at Bank of England base rate
  • Deferred amounts settled when asset is sold, transferred, or appreciation resumes above 2%

What this achieves:

  1. Protects genuinely stagnant assets—no forced sales for assets barely holding value
  2. Preserves long-term revenue—deferred tax isn't forgiven, just delayed
  3. Maintains pressure on under-utilised capital—still incentivises improving returns or releasing assets
  4. Weakens political attacks—neutralises "paper wealth" and "forced sale" objections

Example:

  • £500k property portfolio, barely appreciating (0.5% real growth)
  • Standard wealth tax: £4,000/year (0.8% band)
  • Performance adjustment: Only £1,000 due immediately, £3,000 deferred
  • Deferred amount accumulates at ~5% until property sold or appreciation resumes

Not an exemption: This is timing discipline, not a carve-out. All wealth remains visible, counted, and eventually taxed.

Agricultural Property Exemption:

Agricultural land and buildings used for farming purposes are exempt from the wealth tax.

Qualification criteria:

  • Property must be used for agricultural purposes
  • Owner or close family member must actively farm the land
  • Mirrors current Inheritance Tax Agricultural Property Relief (100% exemption)

Rationale:

  • Food security—protects domestic food production capacity
  • Rural communities—maintains viability of family farms
  • Political sustainability—agricultural land represents only ~£125bn of the ~£8,500bn wealth tax base (1.5%)
  • Policy continuity—maintains current IHT treatment where working farms receive 100% relief

Revenue impact: £1.25bn foregone (1.4% of wealth tax revenue)

Revenue: £84.75bn annual wealth tax + £3bn exit tax = £87.75bn total


3. Land Value Tax: £150bn

Replaces council tax and business rates entirely.

Residential: £114.4bn

  • Rate: 2% annually on land value
  • Land value: Calculated as 60% of total property value
  • Example: £300,000 house = £180,000 land value = £3,600/year
  • Replaces: Council tax (was ~£1,200-2,500/year)

Valuation method:

  • AI-assisted algorithmic valuation using comparable sales
  • Updated annually
  • Appeals process with 90-day resolution target
  • Cap on year-on-year increases: 10% maximum

Initial approach (Years 1-2): Simple formula using 60% of property value from land registry, Zoopla, Rightmove data

Sophisticated approach (Years 3+): Machine learning model using comparable sales, location factors, planning permissions, local amenities, transport links, school quality, environmental factors

Business: £31.5bn

Tiered by use to protect productive activity:

Land Use Rate Rationale
Commercial/Office 1.5% Slight reduction from residential
Retail (high street) 1.0% Support struggling sector
Industrial/Warehouse 0.75% Protect manufacturing
Agricultural 0.25% Food security

Business benefits:

  • London offices: -44% vs current business rates
  • Factories: -75% vs current business rates
  • Encourages efficient land use
  • Discourages speculation
  • Sitting on empty land costs money

Total land tax: £150bn (£114.4bn residential + £31.5bn business + £4.1bn efficiency gains)


4. Carbon Tax: £53.5bn

Comprehensive carbon pricing across the entire economy.

Rate: £130 per tonne of CO₂

What's covered:

  • Petrol and diesel (replaces fuel duty)
  • Heating oil and gas
  • Electricity generation (time-varying by carbon intensity)
  • Aviation fuel
  • Industrial emissions
  • Imports (carbon border adjustment)

Dynamic electricity pricing:

  • Real-time carbon intensity pricing
  • Night (wind-heavy): ~0.5p/kWh carbon charge
  • Peak (gas-heavy): ~2.5p/kWh carbon charge
  • Average household impact: ~£40/year
  • Incentivises demand shifting and renewable investment

Revenue mechanism with uprating:

  • Target: revenue declines 2% yearly in real terms
  • Mechanism: as emissions fall, price per tonne rises to maintain target
  • Safety valve: price capped at £300/tonne (inflation-indexed)
  • After £300 cap: switch to permit trading system

Trajectory example:

Year Emissions (Mt) Price/tonne Revenue
2026 290 £130 £53.5bn
2030 238 £140 £33.4bn
2035 174 £171 £29.7bn
2040 116 £228 £26.5bn
2045 58 £300 (cap) £17.4bn + permits

Household impact examples:

  • Heating oil (6,000L/year): +£2,220/year
  • Average petrol (1,500L/year): +£465/year
  • BUT: offset by council tax abolition (saves £1,200-2,500/year) and NI abolition

Green transition support:

  • Heat pump grants: £15,000 (£18,000 Northern Ireland)
  • EV incentives: 70% discount on road pricing
  • Public transport investment: £8bn
  • Home insulation programme: £10bn

Revenue: £53.5bn (Year 1), declining to £33bn by 2030 as emissions fall 22%


5. Road Pricing: £28bn

Replaces: Vehicle Excise Duty (£7bn) and fuel duty portion (£24bn—balance moved to carbon tax)

Core system:

  • GPS-based distance charging
  • Varies by vehicle type, congestion, time of day, emissions
  • Revenue-neutral for average driver (7,900 miles/year)

Base rates (per mile):

  • Electric vehicles: 2p (70% discount vs petrol—green transition incentive)
  • Petrol/Diesel: 7p
  • Large vehicles (vans/trucks): 15p

Multipliers:

  • City centres (peak): ×2.5 (e.g. 7p becomes 17.5p)
  • City centres (off-peak): ×1.5
  • Motorways: ×1.0 (base rate)
  • Rural roads: ×0.7
  • Night (11pm-6am): ×0.5

Privacy protection:

  • Data encrypted end-to-end
  • Only total distance/charges transmitted
  • No route tracking stored
  • Independent oversight by Privacy Commissioner
  • Annual security audits

Alternative option (for privacy-concerned):

  • Flat £750/year fee (covers average 7,900 miles)
  • No GPS tracking required
  • Slightly more expensive for average driver but provides certainty

Implementation:

  • 2026-2027: Voluntary pilot (10,000 vehicles, £500 bonus)
  • 2027-2028: London, Manchester, Birmingham rollout
  • 2028-2030: National rollout (one region every 6 months)
  • Pre-installed in new cars from 2028

Example annual costs:

  • Rural driver (5,000 miles, mostly off-peak): £275/year (was £200 VED + £350 fuel duty = £550)
  • Suburban commuter (10,000 miles, 30% peak): £625/year (was £200 + £700 = £900)
  • City commuter (12,000 miles, 50% peak): £900/year (was £200 + £840 = £1,040)

Congestion impact:

  • London peak traffic: -15%
  • Other cities: -8-12%
  • Motorway efficiency: +5%
  • Shift to public transport: +18%

Revenue: £28bn (£24bn replacing fuel duty portion + £7bn replacing VED - £3bn transition costs)


6. Corporation Tax: £60bn

Rate: 20% (reduced from 25%)

Why reduce?

  • Internationally competitive (matches Germany, below France's 25%)
  • Offsets employer NI abolition burden on businesses
  • Attracts international investment
  • Combined with no employer NI = most employment-competitive developed nation

Claw-back mechanism (if jobs boom fails):

  • If job creation <400k by end of Year 2 (December 2027)
  • Corporation tax reverts to 22% from April 2028
  • If still <600k by end of Year 3, reverts to 25%
  • Protects revenue if predicted employment boost doesn't materialise

Small business relief:

  • Maintained for profits <£50k (19% rate)
  • Helps micro-businesses and start-ups

Revenue: £60bn (down from £70bn current)


Part 3: Supplementary Revenue Measures

7. Enhanced Digital Services Tax: £16bn

Increased from 2% to 5% on revenues >£10m (lowered from £25m threshold)

What's covered:

  • Tech giants
  • Online gambling platforms
  • Home delivery platforms
  • Social media platforms
  • Search engines
  • Online marketplaces

Key features:

  • Minimum 15% effective tax rate on global profits (OECD aligned)
  • Prevents profit shifting to low-tax jurisdictions
  • Revenue threshold lowered from £25m to £10m to capture more platforms
  • Exemption for businesses operating at <3% margin

Rationale:

  • Digital platforms generate enormous value from UK users
  • Current 2% rate raises only £600m despite sector size
  • 5% rate brings UK in line with France and Italy
  • Ensures tech giants contribute fairly to public services they depend on

Revenue: £16bn (up from £600m current)


8. Exit Tax: £3bn

Separate from ongoing wealth tax.

Structure:

  • One-time 25% charge on net wealth >£1m for those leaving UK to avoid tax
  • Payable over 5 years at 5%/year, OR
  • Agree to continue wealth tax for 10 years regardless of residence

Details:

  • Deterrent effect keeps wealthy taxpayers in system
  • Expected: ~600-800 high-net-worth individuals attempt to leave annually
  • Monthly monitoring with adjustment triggers if emigration exceeds thresholds

Revenue: £3bn/year


9. Financial Transaction Tax: £6bn

Rate structure:

  • Shares: 0.1% on transaction value
  • Bonds: 0.05% on transaction value
  • Derivatives: 0.01% on notional value

What's covered:

  • Government and corporate bonds
  • Derivatives and futures contracts
  • Applies to both buyer and seller (0.05% each on shares)

Exemptions:

  • Initial public offerings (IPOs)
  • Gilt purchases by pension funds
  • Market-making activities (reduced rate of 0.02%)
  • Transactions under £1,000

Collection:

  • Automatic deduction by exchanges and clearing houses
  • Real-time reporting to HMRC
  • Monthly settlement

Rationale:

  • Reduces harmful high-frequency trading
  • Currently UK has 0.5% stamp duty on shares only (raises ~£3.5bn)
  • Comprehensive FTT at lower rate broadens base and reduces avoidance
  • Dampens market volatility without affecting long-term investors
  • Average pension fund pays <£50/year additional

Revenue: £6bn


10. Luxury Goods VAT (30%): £3bn

30% VAT rate applied to high-value goods:

Vehicles:

  • Cars with purchase price >£50k
  • Motorcycles >£25k
  • Motorhomes >£75k

Jewellery & watches:

  • Watches >£5k
  • Jewellery items >£2k
  • Gemstones >£1k

High-end goods:

  • Designer handbags >£2k
  • Fur products (all)
  • Private jets (all)
  • Yachts >40ft
  • Helicopters (all)

Exemptions:

  • Medical vehicles (adapted for disability)
  • Emergency services vehicles
  • Working vehicles (proof of business use)
  • Heirloom jewellery (certified >50 years old)

Rationale:

  • Luxury consumption can bear higher taxation
  • Progressive—only affects wealthy purchasers
  • Discourages conspicuous consumption
  • Minimal economic impact (luxury goods have low price sensitivity)
  • Encourages purchasing of pre-owned luxury goods (no VAT on second-hand)

Anti-avoidance:

  • Registration of high-value goods required
  • Penalties for false business use claims
  • Overseas purchase tracking (customs data sharing)

Revenue: £3bn


11. VAT Registration Threshold Reduction: £2.5bn

Current threshold: £90k turnover
New phased reduction:

  • Year 1 (April 2027): £60k
  • Year 2 (April 2028): £40k
  • Year 3 (April 2029): £25k

Impact:

  • Additional 550,000 businesses register for VAT
  • Removes growth barrier where businesses avoid crossing £90k
  • Aligns UK more closely with EU thresholds

Mitigations:

  • Free HMRC software for businesses <£100k turnover
  • Annual returns for businesses <£50k (instead of quarterly)
  • 6-month VAT-free trading period for new registrants
  • Cash accounting allowed (pay VAT when paid, not when invoiced)
  • Dedicated small business helpline

Rationale:

  • Current £90k threshold is highest in Europe
  • Creates perverse incentive for businesses to stay small
  • Many businesses already voluntarily register (to reclaim VAT on inputs)
  • Levels playing field between small and medium businesses

Revenue: £2.5bn


Part 4: Environmental VAT Reforms

VAT remains at 20% standard rate, but with environmental adjustments. Net revenue impact: £0bn (environmental zero-rating offset by pollution taxes and reverse VAT costs balanced by behaviour change).

Zero-Rated Environmental Goods (Revenue Impact: -£8bn)

Heat pumps & renewable energy:

  • Heat pumps and installation: 0% (was 20%)
  • Solar panels and installation: 0% (was 20%)
  • Home battery storage: 0%
  • Smart thermostats: 0%

Sustainable transport:

  • Electric vehicles: 0% (was 20%)
  • E-bikes: 0%
  • Public transport passes: 0% (was 5%)
  • Bike repairs and servicing: 0%

Energy efficiency:

Increased VAT on Polluting Goods (+£9bn)

Single-use plastics: 40% VAT

  • Plastic bottles
  • Disposable cutlery/plates
  • Plastic bags
  • Plastic packaging

Heavily polluting products: 30% VAT

  • Petrol/diesel vehicles (new)
  • Gas boilers (new installations)
  • Patio heaters
  • Leaf blowers (petrol)

High-emission luxury: 30% VAT

  • Private jets and helicopters (new)
  • Superyachts
  • High-performance petrol vehicles (>300g CO₂/km)

Reverse VAT on Reusables (-£0.25bn cost)

The innovation: Government PAYS 5% on products sold in verified returnable packaging systems.

How it works:

  • Products sold in returnable packaging get 5% government subsidy at checkout
  • Packaging must be part of verified return scheme (95%+ return rate)
  • Industrial sterilisation and reuse tracking required
  • Customer pays deposit (e.g. 20p) which is refunded on return

Examples:

  • Milk in glass bottle (£1.50) → Customer pays £1.43 + 20p deposit
  • Shampoo in refillable container (£4) → Customer pays £3.80 + 50p deposit
  • Takeaway food in returnable container (£8) → Customer pays £7.60 + £1 deposit

Qualifying schemes:

  • Glass bottles with return rates >95%
  • Metal containers with industrial sterilisation
  • Certified reusable food containers
  • Traceable through barcoding/RFID
  • Minimum 20 uses per container

Requirements:

  • Scheme must be independently verified
  • Return infrastructure in place
  • Sterilisation to food safety standards
  • Comprehensive tracking system
  • Annual audit of return rates

Impact:

  • Reusable packaging adoption: 12% → 48%
  • Glass bottle return schemes: +340%
  • Plastic packaging use: -35%
  • Total packaging waste reduction: -28% by 2030

Revenue mechanism:

  • Retailers claim back reverse VAT monthly from HMRC
  • Capped at £250m/year to prevent abuse
  • If cap exceeded, payment reduces proportionally
  • Fraud penalties: loss of scheme certification + fines

Environmental outcome:

  • Single-use plastics: -70% by 2030
  • Heat pump installations: +450%
  • EV adoption: accelerated by 3-4 years
  • Circular economy incentivised through reverse VAT innovation

Part 7: Economic Impacts

Jobs and Growth: +800k to 1.1m Jobs

Job creation mechanisms:

  1. Employer NI abolition (£105.6bn):

    • Saves £4,500 per £30k employee
    • CBI survey: 38% plan to hire more, 42% plan wage increases
    • Estimated: +400-600k jobs
  2. Corporation tax cut (25% → 20%):

    • International competitiveness boost
    • Estimated: +100-200k jobs
  3. Green transition investment (£33bn):

    • Heat pump installations: +200-250k jobs
    • Renewable energy: +50-80k jobs
    • Public transport: +30-50k jobs
    • Total: +280-380k jobs
  4. Construction boom from land tax:

    • Incentivises development of empty land
    • Estimated: +20-80k jobs

Total jobs created: 800k-1.1m over 4 years (200-275k/year)

GDP impact:

  • Year 1: +1.2%
  • Year 2: +1.8%
  • Year 3: +2.2%
  • Year 4: +2.8%
  • Cumulative by 2030: +3.5-4.5% above baseline

Productivity: Estimated +0.3-0.5% productivity growth annually

Distributional Impact: Gini Falls to 0.31

Current UK Gini: 0.355 (high inequality)
After reform Gini: 0.31 (similar to Scandinavia)

Regional Rebalancing

North England:

  • Lower house prices = lower land tax
  • Manufacturing jobs from employer NI cut
  • Green jobs (offshore wind, heat pump installation)
  • Lower wealth = less wealth tax
  • Net effect: North GDP growth +2% faster than South

London/Southeast:

  • High house prices = high land tax
  • High wealth concentration = wealth tax hits hard
  • Financial sector less affected by employer NI
  • But still benefits from NI cuts, jobs growth, simplified system
  • Net effect: Slower growth, but still positive

Scotland:

  • Manufacturing boost
  • Renewables investment (wind, hydro)
  • Lower property values help
  • Oil sector transition support
  • Net effect: +2.5% GDP growth

Wales:

  • Industrial job creation
  • Lower property/wealth
  • Green transition jobs
  • Net effect: +2.2% GDP growth

Northern Ireland:

  • Enhanced heat pump grants (£18k vs £15k)
  • Manufacturing jobs
  • Lower property values
  • Net effect: +2.0% GDP growth

Housing Market: Price Correction of 8-10%

Land value tax impact:

Price falls by segment:

  • London/Southeast: -10-15% (high initial values, most speculation)
  • Regional cities: -5-10%
  • Rural areas: -3-7%
  • National average: -8-10%

Effects:

  • Holding empty land now costs money (2% annually)
  • Buy-to-let less attractive (wealth tax + land tax)
  • Second homes face full taxation
  • Increased supply as speculators sell

First-time buyers:

  • Lower prices help
  • But: Higher interest rates possible
  • Net: Easier to enter market overall

Rental market:

  • Supply increases (landlords sell)
  • Rents stable to falling (-5-10% in hot markets)
  • Better for renters

If revenue >20% below target for 6 months: Stop Year 2 implementation entirely

Annual Go/No-Go Decisions

December 2026: Proceed to Year 2 only if:

  • 10+ indicators green
  • <2 amber, 0 red
  • Jobs >300k
  • Emigration <12k
  • Inflation <5%

December 2027: Proceed to Year 3 only if:

Part 10: Major Risks & Mitigation

1. Wealth Flight

  • Risk: High earners emigrate to avoid wealth tax
  • Mitigation: 25% exit tax, monthly monitoring, adjustment triggers
  • Threshold: Pause if >25k/year emigration

2. Land Valuation Chaos

  • Risk: Appeals overwhelm system, unfair valuations
  • Mitigation: AI-assisted comparable sales, robust appeals, 10% annual cap
  • Threshold: Abandon algorithmic method if >25% appeal rate

3. Inflation Spike

  • Risk: Carbon tax drives prices up
  • Mitigation: Pre-committed pause at 6% inflation, emergency payments
  • Actual impact: Modelled at +0.3-0.5%

4. Road Pricing Rebellion

  • Risk: Public rejection of tracking
  • Mitigation: Flat fee option (£750/year), privacy protections, regional pilots first
  • Fallback: Can maintain at pilot-only if resistance too strong

5. Jobs Boom Failure

  • Risk: Employer NI abolition doesn't create jobs
  • Mitigation: Corporation tax claw-back mechanism if <400k jobs by Year 2
  • Pre-committed: Delay Year 2 if Year 1 <200k

6. Administrative Breakdown

  • Risk: HMRC can't cope with complexity
  • Mitigation: £3bn investment, 10,000 staff, penalty-free first year
  • Monitoring: Error rate tracked monthly

Part 11: International Comparison

Most Employment-Competitive OECD Nation

Employer cost for £30k worker:

  • UK (current): £34,500
  • UK (reformed): £30,000
  • Germany: £34,500
  • France: £38,000
  • US: £32,000 (but higher healthcare costs)

First Major Comprehensive Wealth Tax

Comparable systems:

  • Switzerland: 0.3-1.0% (cantonal, varies)
  • Norway: 1.1% (over ~£150k)
  • Spain: 0.2-3.5% (regional)
  • UK (proposed): 0.8-5.3% (over £100k)

Difference: Progressive, comprehensive, designed with agricultural exemption and performance-based deferral

Highest Carbon Tax in Developed World

International comparison:

  • Sweden: $137/tonne (£107)
  • Switzerland: $120/tonne (£94)
  • UK (proposed): £130/tonne rising to £300 cap
  • France: $52/tonne (£41)

Plus: Environmental VAT system with reverse VAT innovation is globally novel


Part 12: Comparison with Green Party

Similarities

  • Both tax wealth and carbon, not work
  • Both progressive, environmentally focused
  • Both reduce inequality

Key Differences

Policy This Reform Green Party
Wealth Tax £100k threshold, 0.8-5.3%, covers 25% £10m threshold, 1-2%, covers 0.2%
Land Tax Core policy, 2%, replaces council tax "Long-term aspiration", keeps council tax
NI Abolish completely Keep it, increase for high earners
Income Tax £25k allowance, 25/42/47 rates £12.5k allowance, 20/40/45 rates
Carbon Tax £130/tonne, capped at £300 £500/tonne (IFS calls unrealistic)
Revenue Revenue neutral +£172bn tax increases for expansion

Bottom line: Green Party wants bigger state funded by ultra-rich. This reform wants same-sized state funded fairly by taxing wealth/pollution instead of work.

Frequently Asked Questions

Won't wealthy people just leave?

25% exit tax on wealth over £1m creates major barrier. Historical evidence (Sweden, France) shows only small numbers leave. Family ties, social networks, business roots matter. Monthly monitoring with adjustment triggers if needed.

How do you value all properties fairly?

AI-assisted algorithmic valuation using comparable sales, updated annually. Simple formula initially (60% of property value), sophisticated later. Robust appeals with 90-day resolution. 10% annual increase cap.

Won't carbon tax cause inflation?

Modest impact (+0.3-0.5% Year 1) offset by council tax abolition and NI savings. Average household gets £6-9k/year from NI and higher allowance, far exceeding carbon costs of ~£500-1,000/year. Pause trigger at 6% inflation.

What about asset-rich, income-poor pensioners?

Two protection mechanisms: (1) Income-based relief: Can defer land tax and wealth tax payment against property until sale or death if income <£25k. (2) Performance-based deferral: If assets aren't appreciating (growing <2% real terms), part of the tax is automatically deferred and accumulated until value materialises. No forced sales. Protects people staying in homes.

What if my assets aren't generating any returns?

The performance-based deferral mechanism addresses this. If an asset is growing <2% in real terms, you only pay a proportionate share of the wealth tax immediately—the rest is deferred and accumulates at Bank of England base rate. This is settled when the asset is sold or appreciation resumes. This isn't an exemption—it's timing discipline. The system still maintains pressure to either improve returns, repurpose the asset, or eventually release it, but doesn't force immediate fire sales of genuinely stagnant holdings.

How do you know businesses will hire?

£4,500 saving per £30k worker creates huge incentive. CBI survey: 38% plan to hire more, 42% plan wage increases. Historical evidence supports this. Corporation tax claw-back mechanism if targets missed (<400k jobs by Year 2 means CT reverts to 22%).

Won't this be too complicated to implement?

Yes, it's ambitious. That's why: 3-year phase-in, £3bn HMRC investment, 10,000 additional staff, extensive pilots, monthly monitoring, pre-committed adjustment triggers, penalty-free first year. Detailed implementation roadmap with 15 monitored indicators.

What if it all goes wrong?

Pre-committed abandonment triggers: unemployment >8% AND GDP contracts >3%, wealth exodus >50k/year, pound falls >30%, revenue <60% of target for 12 months. Can reverse reforms if necessary (though economically disruptive).

Why are farms exempt from wealth tax but other businesses aren't?

Agricultural land represents only 1.5% of total wealth being taxed (~£1.25bn/year). This exemption maintains current policy (Agricultural Property Relief gives 100% IHT exemption) and supports food security. Other business assets benefit from performance-based deferral if not appreciating. Active business owners manage assets, passive investors do not. Current policy already treats agricultural property differently, and this reform maintains that distinction for political sustainability and rural community support.

Won't reusable packaging be unhygienic?

Strict requirements: industrial sterilisation, food safety certification, traceable cleaning logs, random HSE inspections. Based on successful German model. Penalty regime prevents abuse: contamination = £50k fine + suspension.
