SOME 19 per cent more farmers than forecast will face punitive inheritance tax charges in the first decade of the Government’s new legislation, due to the effect of inflation and frozen reliefs.

That’s according to the latest calculations by the Central Association of Agricultural Valuers (CAAV).

CAAV add that not only has the Government underestimated the number of farmers who will be immediately affected by a factor of five, mainly by overlooking the number of claims only made under business property relief (BPR) and the true value of those claims, but an extra 19 per cent on top of that will be caught by the charges as inflation erodes the reliefs.

“Our calculations point to the first decade of the proposed policy ending with 89,500 farming taxpayers liable for inheritance tax (IHT) on their farm assets,” says Jeremy Moody, secretary and adviser to the CAAV.

“The first 10 years alone would add some 14,500 (19 per cent) to the CAAV’s assessment of 75,000 affected farming taxpayers over a generation - simply because of inflation, if there is no policy change. More would follow as each year goes by.”

The main IHT relief for all taxpayers, the nil rate band, has been frozen at £325,000 since 2009, and the Budget now freezes it to 2030 – 21 years.

“That gives no confidence that the £1m full relief for agricultural property relief (APR) and BPR will be protected against inflation,” says Mr Moody. “Even more farmers would therefore be caught than has been suggested.”

While the nil rate band would be used first for personal assets, which from April 2027 will include unused pension funds, it gives a measure of how inflation brings people into tax.

When full APR and BPR were introduced in 1992, the nil rate band of £140,000 was worth some 56 acres of typical farmland.

The £325,000, frozen since 2009, is now worth 29 acres, protecting less of a farm that would now often be larger than it was then.

“Based on average annual inflation of three per cent since 2009, it’s easy to see how quickly a lot more farmers will fall into this punitive tax band.”

The Central Association of Agricultural Valuers (CAAV) is the specialist professional body representing, qualifying and briefing more than 3,000 members practising in a diverse range of agricultural and rural work throughout England, Wales, Scotland and Northern Ireland.

CAAV members are agricultural and rural valuers who provide professional advice and valuation expertise on issues affecting the countryside from tenancy matters to sales and purchase of farms and land, from taxation and compulsory purchase to auctioneering, and from conservation issues to farming structures.

• From April 2026, farmers and landowners will have to pay a 20 per cent tax on land and assets they inherit over £1 million, with some exceptions.

It is estimated that the tax could impact many farms in Devon, which tend to be 200 to 400-acre family businesses.
