Claiming Business Relief for Inheritance Tax: Executor Guidance
When an estate includes a business, partnership interest, or shares in an unquoted company, personal representatives may be able to reduce Inheritance Tax using Business Relief. This guide explains how Business Relief works, which assets qualify, and how to report claims to HMRC.

When administering an estate that includes commercial property, sole trader interests, partnership shares, or holdings in unquoted private companies, personal representatives face unique responsibilities. Inheritance Tax (IHT) can represent a substantial liability for an estate, but Parliament provides relief mechanisms designed to prevent viable trading businesses from having to be broken up or sold to pay tax liabilities.
Business Relief (formerly known as Business Property Relief or BPR) allows qualifying business assets to be transferred to beneficiaries either completely free from Inheritance Tax or at a reduced rate. However, obtaining this relief is not automatic. Personal representatives must demonstrate to HM Revenue and Customs (HMRC) that all legal conditions are met, report the assets accurately, and submit formal claim schedules alongside the probate tax returns.
Qualifying Assets and Rates of Relief
Under HM Revenue and Customs guidance, Business Relief reduces the net value of qualifying business assets for Inheritance Tax calculations by either 100% or 50%, depending on the nature of the asset and how it was held by the deceased.
Relief of 100% applies to: - A sole trader business or an interest in a partnership. - Unquoted shares in a trading company (including shares listed on the Alternative Investment Market, or AIM).
Relief of 50% applies to: - Shares controlling more than 50% of the voting rights in a fully listed company. - Land, buildings, or plant and machinery owned by the deceased and used mainly in a business carried on by a partnership of which they were a partner, or by a company they controlled. - Land, buildings, or plant and machinery used in a business and held in a trust from which the deceased had a right to benefit.
Identifying which category an asset falls into requires careful scrutiny of company articles, partnership agreements, asset registers, and land registry title deeds.
Essential Criteria: The Two-Year Ownership Rule
To qualify for Business Relief, published HMRC guidance requires that the deceased must usually have owned the business or qualifying assets for a minimum of two continuous years immediately before their death.
There are limited statutory exceptions to the two-year rule: - **Replaced property:** If the deceased sold a qualifying business asset and replaced it with another qualifying asset, the combined period of ownership can count towards the two-year requirement, provided the replacement occurred within a specific timeframe. - **Successive transfers:** If the deceased inherited the property from a spouse or civil partner who had themselves qualified for relief at death, the continuous ownership requirement may be satisfied by combining ownership periods.
If assets were acquired within two years of death through purchase or gift without replacing existing qualifying property, Business Relief will generally be unavailable, leaving the full market value subject to standard Inheritance Tax assessments.
Excluded Assets and Non-Qualifying Businesses
Not all commercial activities or assets held by a business qualify for relief. HMRC enforces strict exclusions to prevent tax relief from being claimed on investment portfolios or passive income assets.
Business Relief is not available if the business consists wholly or mainly of: - Dealing in securities, stocks, or shares. - Dealing in land or buildings. - Making or holding investments (such as residential buy-to-let properties or holiday lets).
In addition, individual assets held within a qualifying trading business may be excluded if they are categorized as 'excepted assets'. An asset is treated as an excepted asset if it was not used mainly for business purposes in the two years prior to death, or if it was not required for future use in the business. For example, excessive cash reserves held within a trading company that are not earmarked for a genuine business purpose may be excluded from relief by HMRC.
How Executors Claim Relief Using Form IHT413
Business Relief must be claimed formally by personal representatives during the probate application process. Claims cannot be made on simplified return forms; instead, executors must complete the main Inheritance Tax account form IHT400.
Alongside form IHT400, personal representatives must complete supplementary schedule IHT413 (Business Property). This schedule requires detailed information, including: - A full description of the business, partnership interest, or shareholding. - The date the business was established or the shares acquired. - Financial statements and balance sheets for the business covering recent accounting periods. - A breakdown of any non-qualifying or excepted assets held by the business. - Professional valuations supporting the figures submitted.
Failing to submit schedule IHT413 correctly or omitting necessary documentation can lead to significant delays in securing a Grant of Representation from HM Courts and Tribunals Service (HMCTS), as HMRC must process the tax accounts before probate can proceed.
Estate Valuation and HMRC Examination
Valuing business assets for Inheritance Tax requires specialist expertise. Unlike cash accounts or publicly traded equities with transparent daily prices, private company shares and partnership interests must be valued based on accounting standards, asset backing, profitability, and market conditions at the exact date of death.
Executors have a legal duty to report realistic market values. HMRC regularly audits claims for Business Relief, examining company accounts, trading activities, and management records. If HMRC determines that a business was primarily an investment company or that cash holdings were excepted assets, relief may be reduced or denied altogether, resulting in unexpected tax bills and potential interest or penalties for the estate.
Where tax is payable on business assets because relief is reduced or unavailable, personal representatives may be eligible to pay the Inheritance Tax in annual instalments over ten years, though interest will accrue on unpaid balances.

Frequently asked questions
Does a buy-to-let property portfolio qualify for Business Relief?
No. HMRC rules specify that businesses consisting wholly or mainly of holding investments, such as residential buy-to-let properties or commercial investment properties, do not qualify for Business Relief.
What happens if a qualifying business is sold during the administration period?
If the deceased qualified for Business Relief at the date of death, the relief applies to the estate value as of that date. However, selling business assets after death may have Capital Gains Tax implications for the estate or beneficiaries.
Can Inheritance Tax on business assets be paid in instalments?
Yes. Published HMRC guidance allows Inheritance Tax on qualifying business property or unquoted shares to be paid in annual instalments over a 10-year period, although interest will be added to the unpaid balance.
