How will new UK farm inheritance tax work?

New UK farm inheritance tax rule begins

A new inheritance tax regime for farms and family businesses in the UK takes effect on 6 April, creating what accountants described as “significant challenges.” The policy introduces a levy on inherited farms and certain family businesses valued at £2.5 million or more.

The change matters for landowners and family enterprises that rely on keeping farmland and operational assets within the family. For many estates, inheritance tax exposure can force difficult decisions such as selling portions of land or borrowing against the estate to fund tax liabilities—particularly in cases where the farming business does not generate liquid funds quickly.

Why accountants flagged problems

Accountants said the rule’s design could create compliance and planning burdens. The central issue is that farm assets often do not translate neatly into cash, while inheritance tax is typically due on a timetable that may not align with seasonal agricultural cash flows.

This can increase the need for earlier estate planning, valuations, and structuring. It can also raise uncertainty for families over how thresholds and rules apply to complex holdings.

Bottom line

Starting 6 April, the UK will levy inheritance tax on inherited farms and family businesses worth £2.5 million or more. Accountants warn the new regime could pose serious planning and financial challenges for farm families.
