Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment her Department made of the potential impact in Wales of increasing the threshold of Agricultural Property and Relief and Businesses Property Relief to £2.5 million.

The Government announced that the allowance for 100 per cent rate of relief will be increased from £1 million to £2.5 million. This means a couple will now be able to pass on up to £5 million of agricultural or business assets tax-free between them, on top of the existing allowances such as the nil-rate band.

Information from claims is not recorded to enable constituency, regional or national breakdowns of the number of estates expected to be affected. However, compared to Budget 2025, the expected number of estates across the UK claiming agricultural property relief, including those also claiming business property relief, forecast to pay more inheritance tax in 2026-27 halves from 375 to 185. Around 85 per cent of estates across the UK claiming agricultural property relief in 2026-27, including those that also claim for business property relief, are forecast to pay no more inheritance tax on their estates under these changes.

Excluding estates only holding shares designated as ‘not listed’ on the markets of recognised stock exchanges, the reforms are also now expected to result in up to 220 estates across the UK only claiming business property relief paying more inheritance tax in 2026-27. This is a reduction from up to 325 such estates forecast to pay more at Budget 2025. This means just over 80 per cent of such estates making claims are forecast to not pay any more inheritance tax.
