Reverse farm inheritance-tax changes

Restore more generous agricultural property relief from inheritance tax for qualifying family farms.

Last updated: May 2026.

Read the policy-specific methodology note

Relief baseline

The baseline is the post-Budget restriction on agricultural property relief. The tax note says most claims remain below the allowance, while the largest estates account for much of the relief cost.

  • Direct winners are inheriting farm estates.
  • Cash-flow pressure may ease for affected farms.
  • Revenue loss is concentrated among larger estates.

Core trade-offs

The policy reduces inheritance-tax pressure on qualifying farms. It also reopens a relief that can protect high-value assets from tax, including where farm ownership is partly an inheritance-tax planning vehicle.

  • Farm heirs gain lower IHT bills.
  • The Exchequer loses estate-tax receipts.
  • Avoidance incentives may increase.

Fiscal impact by 2028-29

+GBP 0.2bn to +GBP 1.2bn. Central estimate: +GBP 0.6bn.

  • Positive numbers mean net fiscal cost; negative numbers mean Exchequer savings.
  • Main cost is lower inheritance-tax receipts.
  • No material offset is assumed.
  • Avoidance and land-price effects are uncertain.
  • This is not an official costing.

Economic impact by 2028-29

  • Jobs: Could protect some farm continuity; broad employment effect is small.
  • Wages: Little direct wage effect for farm workers.
  • Prices: Little direct food-price effect expected.
  • GDP / productivity: Likely small; may preserve inefficient ownership as well as viable farms.

Assessment

The case is strongest for genuinely cash-poor family farms facing forced sales. The fiscal and distributional concern is that generous APR can also shelter large land wealth and encourage tax planning.

Confidence: Medium-low. The tax base is documented, but behavioural estate-planning responses are uncertain.

Main risks

  • Avoidance channel: Generous relief can attract non-farming wealth into agricultural land.
  • Distribution: Cash gains skew toward estates large enough to face tax.
  • Land prices: Tax relief can capitalise into agricultural land values.

Safeguards

  • Target active farming businesses only.
  • Cap relief per estate clearly.
  • Publish estate-size distribution of gains.

Tax design principles

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.
