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
+GBP 2.5bn - Net fiscal impact in 2028-29
Low case: +GBP 0.8bn. High case: +GBP 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 GBP 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 GBP 3bn gross.
- Offsetting tax receipts from fewer closures: GBP 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: +GBP 3.0bn
- Higher receipts from surviving firms: -GBP 0.4bn
- Administration and boundary policing: +GBP 0.1bn
- Local funding adjustment: -GBP 0.2bn
Central net impact: +GBP 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: +GBP 0.5bn. Preparation or partial implementation.
- 2027-28: +GBP 1.8bn. Main ramp-up year.
- 2028-29: +GBP 2.5bn. Target-year central estimate.
- 2029-30: +GBP 2.5bn. Continuation at steady-state assumptions.
