The Welsh Conservatives will bring forward a Senedd motion next week calling on the UK Government to reverse its decision to impose a family farm tax on agricultural businesses.
From April 2026, inherited agricultural assets worth more than £1m, which were previously exempt, will be liable to the tax at 20 per cent.
Thousands of farmers gathered in Westminster earlier this week in protest of the changes.
NFU Cymru says the move poses a threat to the family farm structure and the nation’s food security.
Many farmers have argued that while they are asset rich - such as in terms of livestock and land - they are cash poor and these changes would mean they would need to sell up their farms in order to be able to pay the tax.
Prime Minister Keir Starmer says he understands farmers’ concerns, but has insisted that the "vast majority" of farms will be unaffected
Welsh Conservative Shadow Minister for Rural Affairs, James Evans MS, said: "Labour's family farm tax will put family farms out of business, threaten our food security, and lead to food prices rising.
"Only the Welsh Conservatives will stand up for our farmers, and that's why we're bringing forward a Senedd motion calling on Labour to reverse this decision.
"No farmers, no food."
NFU Cymru President, Aled Jones, added: “Earlier this week, hundreds of farmers from across Wales journeyed to London to meet with their MPs and register their deeply held concerns about these misguided and ill-thought-out reforms to Agricultural Property Relief and Business Property Relief.
“The proposals unveiled by the Treasury last month to introduce a tax on the passing on of our family farms to the next generation is a massive added burden and will leave many farmers with neither the means, confidence nor the incentive to invest in the future of their business.
“NFU Cymru reiterates its call for the UK Government to halt these changes.”
The motion which will be debated next week reads:
To propose that the Senedd:
