UK Family Firms Warned: Inheritance Tax Reform Could Force Sales or Exile
Owners face capped relief that may drive exits, sales, and long-term uncertainty for multigenerational businesses
Many family business owners across the UK say tax advisers are now urging them to sell their firms or relocate abroad in response to upcoming inheritance tax changes.
Under reforms taking effect in April 2026, Business and Agricultural Property Reliefs will be limited: the first one million pounds of qualifying business or farm assets remains fully exempt, but anything above that will receive only fifty percent relief, effectively triggering a twenty-percent tax on the excess.
Owners describe the new rules as a sharp break from tradition—advisers are recommending offshore trusts, shifting shares abroad, or outright sale to meet future liabilities.
Some are already pausing investment or putting succession plans on hold rather than risk overwhelming tax burdens.
Independent research supports their anxiety: a comprehensive national survey of over four thousand family businesses warns that reforms could lead to a reduction of £14.9 billion in economic output and the loss of more than 200,000 jobs between 2026 and 2029.
The study also finds that over half of affected firms have already cancelled or postponed investment, and nearly a quarter have halted recruitment.
Agricultural interests may be somewhat protected: analysis by taxation researchers suggests most farm estates impacted by the reforms could absorb additional tax without selling land, though about seventy estates per year may still face unsustainable tax burdens.
Political reaction is mounting.
A recent Westminster Hall debate saw MPs warn that changes could jeopardize family farms and local economies.
The National Farmers’ Union has backed a House of Lords inquiry into the reforms.
Many within the sector argue the shift ushers in an era where building a multi-generation business is no longer viable in the UK.
