Business Relief Changes 2026: Inheritance Tax Impact & What to Do

The UK’s Business Relief (formerly Business Property Relief) and Agricultural Property Relief (APR) have long been cornerstones of inheritance tax planning, allowing business owners and investors to pass down their assets tax-efficiently. However, major reforms that took effect on 6 April 2026 have altered how relief is applied, particularly for estates exceeding £2.5 million. These changes signal a shift in how the government approaches wealth transfer taxation, prompting business owners and investors to reassess their strategies.

What Is Business Relief (BR)?

Business Relief is a tax incentive designed to reduce Inheritance Tax (IHT) on qualifying business assets. For decades, BR has allowed eligible businesses to benefit from 100% relief, ensuring continuity for heirs without the need to liquidate assets to cover massive IHT bills.

Key business assets qualifying for BR include:

• Shares in unlisted trading companies or companies listed on AIM (Alternative Investment Market).
• Ownership of a business or interest in a partnership.
• Land, buildings, and machinery used wholly for business purposes.

Similarly, Agricultural Property Relief (APR) provides tax relief on qualifying farmland, buildings, and farming businesses, helping landowners mitigate estate tax liabilities.

What Are the 2026 Business Relief Changes?

The government’s new tax policy introduced a cap on the 100% relief, meaning estates above the threshold are subject to higher tax liabilities. Here’s a breakdown of the key changes:

• 100% relief applies only to the first £2.5 million of combined qualifying business and agricultural property, per person (including lifetime gifts and trusts). Any unused allowance transfers to a spouse or civil partner, and the allowance is indexed with CPI from 6 April 2031.
• Assets exceeding £2.5 million receive only 50% relief, meaning a portion of the estate is subject to IHT.
• AIM-listed shares see reduced tax advantages, with the relief dropping from 100% to 50%.
• The scope of qualifying assets may be redefined, affecting eligibility for BR and APR.

The changes primarily target larger estates, ensuring that high-value business assets contribute more to inheritance tax revenues. While these reforms aim to rebalance tax relief, they introduce new complexities for business owners planning generational wealth transfers.

Key Business Relief Changes in 2026: What You Need To Know

While many estates benefiting from BR and APR will remain unaffected, those exceeding £2.5 million in business assets face significant tax increases. The sectors most impacted by these reforms include:

• High-Net-Worth Business Owners: Entrepreneurs with thriving businesses valued beyond the threshold will need to reassess their estate planning. High-net-worth individual? Explore tailored tax strategies designed for you.
• Agricultural Investors & Landowners: Farmers and rural estate owners with extensive land holdings could see higher tax exposure.
• AIM Market Investors: Individuals with substantial investments in AIM-listed companies will lose full inheritance tax exemption.
• Family-Owned Businesses: Generational businesses structured to benefit from BR will need to explore alternative tax planning strategies.

How to Prepare for Business Relief Changes in 2026

Despite the changes, there are several proactive tax planning strategies that business owners can implement to minimise their inheritance tax liabilities:

Restructuring Business Holdings

Adjusting the structure of a business can optimise tax efficiency, especially for estates exceeding the £2.5 million threshold. Business owners may explore group structures or holding companies to better manage tax exposure.

Leveraging Trusts and Family Investment Companies (FICs)

Setting up trusts or FICs allows businesses to transfer assets strategically, reducing taxable estate value while maintaining control.

Early Succession Planning

Business owners should start estate planning early to mitigate the impact of higher IHT charges. Phased transfers, lifetime gifts, and other strategies can help heirs retain control of business assets with reduced tax burdens.

Maximising Other Tax Reliefs

Using tax-efficient investment schemes like Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) can help reduce taxable estate values.

Consulting a Professional Tax Advisor

With changing tax laws, working with a tax specialist is crucial. A tailored estate planning strategy can ensure compliance while optimising tax relief.
