Methodology note
Abolish rates for high-street firms: calculation note
Scenario assumptions behind the Abolish rates for high-street firms estimate. The figures are illustrative and exclude unrelated Conservative pledges.
Central fiscal result
+£2.5bn - Net fiscal impact in 2028-29
Low case: +£0.8bn. High case: +£6.0bn. Positive numbers are fiscal costs or borrowing pressure. Negative numbers are Exchequer savings or receipts.
Scenario and baseline
- Model rates abolition for qualifying high-street firms by 2028-29.
- Central case assumes £2.5bn net annual relief.
- Baseline uses business-rates receipts and existing reliefs.
- No replacement online tax is included centrally.
Affected population
- Affected population is business premises, not companies or workers.
- Direct exposure includes shops, pubs, cafes and local services.
- Indirect exposure includes landlords, councils and consumers.
- Existing small-business relief reduces additional gains for some premises.
Gross impact
- Central relief cost: about £3bn gross.
- Offsetting tax receipts from fewer closures: £0.5bn.
- High case assumes broad eligibility and weak offsets.
- No dynamic town-centre uplift is scored.
Fiscal build-up, central case
- Lost business-rates revenue: +£3.0bn
- Higher receipts from surviving firms: -£0.4bn
- Administration and boundary policing: +£0.1bn
- Local funding adjustment: -£0.2bn
Central net impact: +£2.5bn in 2028-29.
Behaviour and pass-through
- Low case assumes narrow eligibility and strong existing relief overlap.
- Central case assumes targeted retail, hospitality and local-service relief.
- High case assumes broad premises coverage and landlord capture.
- Price pass-through to consumers is uncertain and not fiscal-scored.
- Business survival effects are treated cautiously.
Phasing
- 2026-27: +£0.5bn. Preparation or partial implementation.
- 2027-28: +£1.8bn. Main ramp-up year.
- 2028-29: +£2.5bn. Target-year central estimate.
- 2029-30: +£2.5bn. Continuation at steady-state assumptions.
Main source groups
- Conservative Party, "Stronger High Streets" (2026): Used to define the pledge wording, policy scope and implementation scenario being modelled.
- Ministry of Housing, Communities and Local Government, "Non-domestic rating collected by councils: forecast for 2026 to 2027" (2026): Forecast business-rates data include receipts and reliefs collected by councils; anchors possible high-street rate relief costs.
- Office for Budget Responsibility, "Economic and fiscal outlook: March 2026" (2026): The OBR forecast sets the macro, borrowing and receipts baseline used for broad fiscal context; prevents treating tax cuts or spending changes as self-financing.
- HM Revenue and Customs, "Direct effects of illustrative tax changes bulletin" (2025): HMRC provides direct-effect estimates for illustrative changes to SDLT, VAT, fuel duties and other taxes; anchors tax costs before behavioural and macro adjustments.
- Mirrlees and review team, "Tax by Design: The Mirrlees Review" (Institute for Fiscal Studies and Oxford University Press, 2011): Efficient tax systems use broad bases, coherent rates and few arbitrary reliefs; frames the efficiency trade-off when tax cuts are not matched by credible funding.
- Saez, Slemrod and Giertz, "The Elasticity of Taxable Income with Respect to Marginal Tax Rates" (Journal of Economic Literature, 2012): Higher-income taxpayers respond more strongly to tax-rate changes through avoidance, timing and real behaviour; important where the policy changes top-pay, capital or business-tax incentives.
- Conservative Party, "Our Plan for Britain" (2026): Used to define the pledge wording, policy scope and implementation scenario being modelled.
