Why business owners should review succession, sale and tax planning before April 2026
Planned changes to Inheritance Tax from April 2026 could significantly affect how family businesses, farms and privately owned companies are passed on to the next generation.
For many business owners, most of their wealth is tied up in the company they have spent years building. These changes may therefore have a material impact on succession planning, estate planning and future sale decisions.
If you own a business valued above £2.5 million, or expect your business to grow beyond that level, now is the time to review your position and understand your options.
What is changing?
Historically, qualifying trading businesses and agricultural property could often be transferred on death with up to 100% Inheritance Tax relief, provided the relevant conditions were met. From 6 April 2026, each individual is expected to have a £2.5 million allowance qualifying for 100% Agricultural Property Relief and/or Business Property Relief. Asset values above this allowance are expected to receive 50% relief rather than full exemption. With Inheritance Tax charged at 40%, this could create an effective tax rate of up to 20% on the excess value.
This means some business owners who previously expected their shareholding to pass to the next generation free from Inheritance Tax may now face a potential liability.
Why this matters
These reforms create three important planning considerations for business owners.
Business value may create unexpected exposure
Many privately owned businesses have grown significantly in value. A business that once sat comfortably within the relief limits may now create a potential Inheritance Tax exposure. An up-to-date valuation can help you understand whether there is an issue and how significant it may be.
Liquidity may become a challenge
Inheritance Tax is typically due within six months of death. Without appropriate planning, an estate may need to raise funds quickly, potentially through the sale of assets or shares. This can place pressure on the family, the business and the succession plan at a sensitive time.
Qualification for relief is technical
Relief usually applies to qualifying trading assets. Surplus cash, investment activity, non-core property or certain group structures may affect eligibility. Reviewing the structure of the business in advance can help identify issues before they become more difficult to resolve.
Planning before April 2026
The changes may prompt wider conversations around ownership, succession, liquidity and long-term value. Depending on your circumstances, you may wish to consider:
- obtaining a current valuation of your business
- reviewing which assets may qualify for relief
- modelling potential Inheritance Tax outcomes under different scenarios
- reviewing shareholder agreements and succession plans
- updating your Will alongside wider corporate and tax planning
- considering whether a partial sale, investment or future exit could support your personal and commercial objectives
These decisions should not be rushed. The right approach will depend on your business, your family circumstances and what you want to achieve next.
