Reform UK - Business tax
Replace some high-street business rates
Abolish business rates for high-street SMEs and add an online delivery tax on large firms.
Last updated: May 2026.
Rates baseline
Reform's 2024 Contract proposed abolishing business rates for high-street SMEs, funded by a 4% online delivery tax. Business rates receipts are about GBP 34bn overall.
- Business rates receipts are about GBP 34bn.
- Only high-street SMEs are modelled as exempt.
- Online tax base is weakly specified.
Core trade-offs
Physical high-street businesses gain lower fixed costs. Online retailers and delivery users face higher costs, while the Exchequer depends on a new, uncertain tax base.
- High-street SMEs gain fixed-cost relief.
- Online customers and firms bear costs.
- New tax base may be avoidable.
Illustrative fiscal impact
-GBP 1.0bn to +GBP 8.0bn. Central estimate: +GBP 2.0bn.
- Positive numbers mean public-finance pressure; negative numbers mean Exchequer savings.
- GBP 34bn rates is the main scale marker.
- Gross costs and receipt offsets are separated in methodology.
- Behaviour and pass-through widen the range.
- This is not an official costing.
Economic impact by 2027-28
- Jobs: May support high-street jobs, but online retail and logistics hiring could weaken.
- Wages: No direct wage effect; owners and landlords may capture relief.
- Prices: High-street prices may fall; online delivery prices likely rise.
- GDP / productivity: Could protect lower-productivity retail space and tax more efficient distribution.
Assessment
The policy targets a real fixed-cost problem for high-street firms, but replacing property taxation with an online delivery tax is not automatically efficient. Relief may be captured by landlords, and the online tax could raise consumer prices while penalising more productive distribution models.
Confidence: Low. Rates receipts are clear, but high-street eligibility and online-tax design are too vague for a narrow range.
Main risks
- Landlord capture: Business-rate relief may feed into higher rents after leases reset.
- Online pass-through: Delivery taxes are likely passed to consumers or suppliers.
- Local funding: Councils need replacement funding if business-rate revenue falls.
Safeguards
- Define high-street SME eligibility precisely.
- Publish online-tax base and avoidance rules.
- Protect council funding through transparent grants.

Tax design and property taxes
The Mirrlees Review criticises inefficient business-property taxation and favours better-designed tax bases.
Supports reforming business rates, but not necessarily replacing revenue with online taxes.

Corporate tax competition
Business taxes can affect location, investment and reporting decisions.
Relevant to pass-through and avoidance risks in targeted online taxation.

VAT pass-through asymmetry
VAT cuts are less fully passed through to consumers than VAT increases in the evidence studied.
Warns that retail tax cuts may partly raise margins instead of prices falling.
