A practical guide to understanding the potential liability and the decisions that deserve review.
From 6 April 2026, the value of qualifying agricultural and business property that can receive 100% relief is limited.
…before considering exemptions, ordinary nil-rate bands and the rest of the estate.
Business Relief remains extremely valuable. The business still needs to qualify, and the precise result depends on the type of business, the assets and activities within it, who owns the shares, what happens on the first death, and whether the business is retained or sold.
What could the new limit mean?
Sarah and David each own half of a qualifying trading company worth £6 million. Assume both shareholdings qualify, neither allowance has previously been used, the first spouse's unused allowance transfers to the survivor, the business remains in the estate on the second death, and other estate assets and ordinary nil-rate bands are ignored so that the Business Relief calculation can be seen clearly.
| Calculation | Amount |
|---|---|
| Combined 100% Business Relief allowance | £5,000,000 |
| Qualifying business value above the allowance | £1,000,000 |
| Value remaining after 50% relief | £500,000 |
| Potential Inheritance Tax at 40% | £200,000 |
The calculation is relatively simple. The practical questions are harder:
Simplified illustration only. It assumes the company and shareholdings qualify and ignores ordinary nil-rate bands, exemptions and other estate assets. The actual position depends on the business, owners, wills and tax rules applying at the time.
Not every pound on the company balance sheet necessarily receives the same treatment.
Business Relief can apply to a qualifying trading business or shares in a qualifying trading company. The detailed result depends on what the company actually does and what its assets are being used for.
A genuine trading business may qualify. A company mainly holding investments, property or other non-trading assets may not.
Money held for a credible acquisition, expansion, investment or identifiable business risk may also have a documented commercial purpose.
Cash, investments or property that are not required for the business may be excluded from relief or contribute to a wider challenge over the company's activities.
This does not mean every surplus pound should immediately leave the company. It means the purpose should be understood, documented, and reviewed as the balance grows.
Unused 100% Business Relief allowance may transfer between spouses or civil partners. That does not mean every couple will automatically receive the intended result.
A business may be owned entirely by one spouse, jointly, through different share classes or alongside other family members.
The surviving spouse may need:
The wills and shareholder arrangements need to work together. An outdated will can undermine an otherwise sensible business and estate plan.
A business that previously qualified for relief may become cash and investments within the survivor's estate.
Gifting shares may sometimes form part of the plan. It also changes control and ownership and can create Capital Gains Tax, commercial and family consequences.
The transaction timetable can reduce the options available. The personal estate plan should be reviewed before the structure becomes irreversible. Deferred payments, retained shares and the timing of completion may all affect the household plan.
Inheritance Tax attributable to qualifying business property can generally be spread over ten annual interest-free instalments, subject to the rules. That helps with timing. It does not remove the need for a funding plan.
The calculation is only the beginning.
Use a realistic current estimate rather than the price the owner hopes to receive one day.
Review the company's trading activity, ownership, cash, investments, property and other assets with the accountant or tax adviser.
Model the first death, the second death, transferred allowance, spouse or civil-partner needs, wills and share ownership.
Consider whether the family or company could fund the liability without damaging the business, forcing an unsuitable sale, or leaving beneficiaries with an avoidable cashflow problem. Life insurance may sometimes help fund the liability, but it does not correct weak ownership, outdated wills or a business that does not qualify.
Show how the estate and Inheritance Tax exposure change if the family receives cash or investments instead of qualifying business shares.
Chapter3 brings these questions into the owner's wider financial plan. The work is coordinated with the company accountant, solicitor, tax adviser, insurance specialists, and corporate-finance advisers where a sale is being considered. The review connects business value to:
Does the current business value sit above the available allowance?
A 30-minute introductory call is enough to discuss:
Rough figures are enough for the first conversation. A recent set of accounts, approximate business value, current shareholding and copies of the wills are useful starting points.
If the existing structure already appears appropriate and the main risks are being dealt with, I will say so.
This guide is general information and does not constitute personal financial, investment, tax or legal advice.
Business Relief depends on the nature and activities of the business, ownership, asset use, transaction timing and the legislation applying at death or transfer. Business valuations, excepted assets, lifetime gifts, trusts, share reorganisations, wills and business sales require specialist tax and legal advice.
The £2.5 million allowance, transferable allowance and 50% relief rules described in this guide apply from 6 April 2026 and may change in future. Investments can fall as well as rise, and investors may receive back less than they invest.
