Business Asset Disposal Relief UK: Entrepreneurs' Relief Guide
Business asset disposal relief UK can reduce the capital gains tax you pay when you sell all or part of your business or qualifying shares. This guide explains BADR capital gains, who qualifies, how to calculate the tax saving and practical steps to take when selling company shares tax.
What is Business Asset Disposal Relief (BADR)?
Business Asset Disposal Relief, often still called entrepreneurs relief, is a capital gains tax relief that can reduce the rate of tax on qualifying disposals to 10%. The relief applies to gains from the sale of whole businesses, qualifying business assets and, in many cases, shares in a personal company.
The relief is available to individuals and trustees who meet specific conditions. It is normally claimed as part of your Self Assessment tax return and can significantly lower the tax bill on a sale that would otherwise be taxed at higher capital gains rates.
Why BADR matters for UK small business owners
Selling a business or company shares is one of the most important financial events for a founder or director. A lower capital gains tax rate can:
- Increase the net proceeds you keep after tax
- Make exit negotiations smoother by clarifying post-tax expectations
- Allow you to plan reinvestment, pensions or philanthropy with greater certainty
Because BADR affects an individual tax position, it is important for founders and shareholders to consider extraction timing, ownership structure and documentation before a sale is final.
Who qualifies for business asset disposal relief UK?
Qualifying is not automatic. You need to meet tests on ownership, employment or involvement in the business, and the nature of the disposal. The key conditions include:
- You must be an individual, or a trustee in some cases
- The business must be a trading company or hold trading assets
- You need to be a sole trader, business partner, or hold at least 5% of the ordinary share capital and 5% of the voting rights in a ‘personal company’ to claim on shares
- You must have owned the business or shares for at least two years before the disposal (this is the standard qualifying period)
If you are selling shares, the company must be your personal company at the time of disposal. The detailed tests are set out by HMRC and can be technical – it is wise to check the rules on GOV.UK and speak to an accountant.
What counts as a qualifying disposal?
Not every sale triggers BADR. Typical qualifying disposals include:
- Sale of a sole trader business
- Sale of a partnership interest by a qualifying partner
- Sale of shares in your personal company that meets the trading and ownership tests
Disposals that are unlikely to qualify include those involving investment companies or where the business primarily holds property for investment rather than trading.
How BADR capital gains are calculated
The mechanics are similar to standard capital gains calculations, but the taxable rate differs. Steps are:
- Calculate the total disposal proceeds
- Deduct allowable costs and the base cost to arrive at the chargeable gain
- Apply any available reliefs or losses to reduce the gain
- If BADR applies, the qualifying portion is taxed at 10% rather than the usual capital gains rates
Remember that you must still use your annual CGT allowance against gains before BADR is applied. For the tax year 2026/27 the annual exempt amount may differ from previous years, so check the current allowance or seek advice.
Example: founder selling shares
Consider a director who sells all their shares in a qualifying trading company and realises a gain of £500,000. With BADR the tax is:
- Apply the annual exempt amount first (if available)
- Remaining gain taxed at 10% under BADR
Without BADR the gain could be charged at 20% for higher-rate taxpayers on most business disposals, meaning BADR saves a substantial sum. Real-life calculations must factor in personal allowances, the capital gains annual exemption and any outstanding losses.
Selling company shares tax – special considerations
When selling company shares there are issues beyond BADR eligibility to consider. These include:
- Whether the company qualifies as a trading company or holds too many non-trading assets
- The structure of share classes and whether your holding meets the ownership tests
- The availability of other reliefs such as holdover relief or Gift Holdover Relief, if you transfer assets rather than sell them
Because share sales often involve multiple shareholders, pre-sale reorganisation or shareholder agreements may be needed to ensure BADR is available and fairly applied.
How entrepreneurs relief differs from BADR
Historically the relief was known as entrepreneurs relief. The name change to Business Asset Disposal Relief clarifies the scope, but many practitioners still use the term entrepreneurs relief.
The important point is that the qualifying conditions and tax rate that apply are those set out under BADR. Do not assume old rules or informal language will reflect current legislation.
Claiming the relief – practical steps
To claim BADR you will typically need to do the following:
- Confirm you meet the ownership and trading tests for the two-year qualifying period
- Gather documents – contracts, share certificates, minutes, historical accounts and ownership records
- Calculate the gain and the portion you claim as qualifying for BADR
- Make the claim on your Self Assessment return or via the correct form if required
If the disposal is part of a larger corporate transaction you may need legal and tax advice to structure the claim and documentary evidence.
Records you should keep
HMRC expects good records. Keep:
- Sale contracts and completion statements
- Share transfer forms and Companies House filings
- Company accounts and board minutes demonstrating trading activity
- Any correspondence that confirms your role and qualifying ownership
Retain records for at least the period HMRC can open enquiries – generally six years, but complex cases can attract longer investigation windows.
Interaction with other reliefs and losses
BADR can be used alongside other reliefs, but there are order and interaction rules to consider. Common interactions include:
- Using the annual exempt amount against gains before applying BADR
- Offsetting carried-forward capital losses against gains before tax calculations
- Considering whether Business Asset Rollover Relief or Entrepreneurs' relief for trustees could be relevant
When multiple reliefs are available, sequence matters. A tax adviser can model the best approach for your circumstances.
Timing and exit planning
Timing can make a large difference to tax outcomes. Things to think about include:
- Holding shares long enough to meet the two-year ownership test
- Timing a sale to make best use of personal allowances and lower tax years
- Considering phased disposals to use annual exemptions over different tax years
Good exit planning often starts well before a sale is marketed. Engage professional advisers early to preserve BADR where possible.
Common pitfalls and how to avoid them
Business owners often trip up on technical tests or poor documentation. Watch out for:
- Assuming all sales of a company are qualifying disposals
- Failing to evidence your 5% shareholding or involvement in the business
- Overlooking the impact of non-trading activities in the company
Avoid these problems by maintaining clear records, checking trading status annually and seeking advice before any restructuring.
Costs of compliance and professional help
Claiming BADR can be straightforward for simple sole trader sales, but share disposals in incorporated businesses are typically more complex. Costs to expect include:
- Accountancy fees to calculate gains and prepare tax claims
- Legal fees for share sale agreements and warranties
- Financial advice for post-sale wealth management
Hiring an adviser with experience in exits and share disposals can reduce tax risk and help you keep more of the sale proceeds.
Practical checklist before you sell
- Confirm the company is a trading company and not mainly investment property
- Verify you meet the 5% shareholding and voting tests for at least two years
- Check your records – share certificates, agreements and board minutes
- Understand how the gain will interact with annual allowances and losses
- Decide when and how to claim BADR on your tax return
Use this checklist as a starting point. Complex transactions will need tailored planning.
Working with advisers – what to ask
When you engage advisers, ask questions such as:
- Have you handled BADR claims for share disposals like mine?
- How will you evidence the trading status and my qualifying ownership?
- Can you model post-tax proceeds under different scenarios?
Choosing advisers who understand founder exits and selling company shares tax issues will make the process smoother.

Frequently asked questions
What is the difference between entrepreneurs relief and BADR?
Entrepreneurs relief is the older name commonly used in practice. The formal name now is Business Asset Disposal Relief. The relief rules are the ones currently set out by HMRC and apply to qualifying disposals.
How long do I have to have owned the business or shares before I can claim BADR?
The standard qualifying period is two years immediately before the date of disposal. Certain exceptions can apply in reorganisations, but you should check the specific circumstances with an accountant.
Can I claim BADR if the company owns a lot of property?
If the company primarily holds property for investment rather than trading, it may fail the trading company test and BADR might not apply. Each case requires a facts-and-circumstances assessment.
What happens if I sell shares in stages?
You may be able to claim BADR on the qualifying portion of each disposal, but the exact tax outcome depends on ownership levels, timing and use of annual exemptions. Staged disposals may be useful for tax planning.
How do I claim BADR on my tax return?
You normally claim BADR on your Self Assessment tax return for the year of the disposal. You should include the details of the gain and note the relief claimed. Complex disposals might require additional forms or HMRC notifications.
