Business Relief for Inheritance Tax: A Complete Guide


Business Relief for Inheritance Tax

September 30, 2025

Inheritance tax (IHT) is often seen as a complex and sometimes costly part of estate planning in the UK. For many families and business owners, the idea of passing down wealth is accompanied by concerns about how much will be lost to tax. This is where Business Relief, also known as Business Property Relief (BPR), becomes a vital tool in effective inheritance tax planning.

Business Relief can significantly reduce or even eliminate the inheritance tax due on qualifying business assets. With the right strategy and the support of an experienced inheritance tax advisor, families can protect more of their hard-earned wealth for future generations.
 

What is Business Relief?


Business Relief (BR) is a valuable tax relief offered by HMRC that reduces the value of certain business assets when calculating inheritance tax. In essence, it helps business owners pass on qualifying assets such as family businesses, shares, or partnerships with reduced or no inheritance tax liability.

Business Relief was first introduced in 1976 as a way to ensure that family-owned businesses could continue operating after the death of an owner, rather than being sold to pay an inheritance tax bill. Today, it remains one of the most important exemptions within the UK inheritance tax system.
 

How Does Business Relief Work?


The relief works by reducing the taxable value of business assets passed on as part of an estate. Depending on the type of asset, Inheritance Tax can be reduced by either:

  • 100% relief: For certain business assets such as shares in an unlisted company, a sole trader’s business, or a partnership interest.
  • 50% relief: For assets like land, buildings, or machinery used in a business that the deceased controlled or held shares in (with voting rights of more than 50%).


This means that if an estate contains qualifying business assets, the inheritance tax liability may be greatly reduced or completely removed.
 

Who Qualifies for Business Relief?


Not every business or business asset qualifies for Business Relief. HMRC has clear eligibility criteria, and careful inheritance tax planning is essential to ensure compliance.
 

Businesses that qualify:

  • Sole trader businesses
  • Partnerships
  • Unlisted trading company shares
  • Holdings of at least 50% in a listed company


Businesses that do not qualify include:

  • Companies mainly dealing in securities, stocks, land or property investments
  • Businesses not trading (investment businesses)
  • Assets wholly or mainly held as non-business assets


Key Benefits of Business Relief in Inheritance Tax Planning

 

  • Preservation of family businesses: Ensures businesses can stay within the family rather than being sold to cover tax obligations.
  • Tax efficiency: Potential to offset large parts of inheritance tax liability, sometimes reducing it to zero.
  • Flexibility: Applies to a range of asset types, giving business owners multiple planning strategies.
  • Certainty: With the right inheritance tax advice, families can plan estates with clarity about future liabilities.


Common Mistakes to Avoid


Even though Business Relief is generous, mistakes in planning can reduce or remove eligibility. Common pitfalls include:

  • Assuming all business assets qualify without a professional review.
  • Failing to trade for the required two years before death actively.
  • Overlooking the fact that land and buildings used by a business owned by the deceased may not qualify fully.
  • Not keeping up with HMRC’s latest rules on what qualifies.


This is why working with an experienced inheritance tax specialist is crucial. They can ensure compliance while maximising benefits.
 

The Role of Professional Inheritance Tax Advice


Inheritance tax legislation can change and contains many nuances. For anyone considering Business Relief as part of their estate planning, professional guidance is essential.

An inheritance tax advisor can:

  • Assess whether your business qualifies.
  • Structure ownership and asset distribution effectively.
  • Integrate Business Relief into wider inheritance tax planning.
  • Reduce the risk of disputes or unexpected tax bills.
