Founders’ Relief: what to check now in your records, ownership and exit plan

HM Treasury has opened a consultation on Founders’ Relief, with a proposed 10% Capital Gains Tax rate on qualifying share disposals and a £10 million lifetime limit, intended to apply to qualifying disposals made on or after 6 April 2027. That is useful context, but the practical decision for founders is simpler: if you may one day sell or transfer shares, can you prove you qualified?

The proposed relief is not a reason to change your business just for tax reasons. It is a reason to tighten the way you already record ownership, control and company history. If the eventual rules include detailed eligibility checks, weak records can become a problem long before any sale is on the table.

1. 1

   Your ownership history

   Check how shares were issued, when they were issued and whether any transfers, conversions or option exercises changed the picture. The consultation and policy paper both point to conditions around founder status and share holding periods, so you need a reliable timeline.

2. 2

   Your cap table versus your records

   Make sure the spreadsheet version of ownership matches board minutes, shareholder agreements, filings and any side letters. If the story only exists in one place, it is fragile.

3. 3

   Your founder assumptions

   People sometimes say someone is a founder because they were there early, even if the legal position is different. Test that assumption now. The policy paper refers to conditions around holding ordinary shares and being a founder at the point trading started.

4. 4

   Your company evidence

   The policy paper notes company conditions around UK corporation tax scope, substantial UK presence, trading-company status, continuity of trade and growth thresholds. You do not need to write a tax memo yourself, but you should be able to find the documents that show how the business evolved.

5. 5

   Your exit path

   Think through what kind of exit you might want: share sale, partial sale, reorganisation or bringing in a new investor. Different paths can create different paperwork and timing issues. Planning early gives you more choices later.

If you want a simple rule, use this: anything that affects ownership should be recorded in more than one place, and those places should agree. That includes share allotments, transfers, option grants, vesting changes, investor rights and any amendments to shareholder terms.

• Keep a dated ownership timeline from incorporation onwards.
• Store board and shareholder approvals alongside the transaction that needed them.
• Review whether any historic transfers were completed properly.
• Check whether option grants, vesting and exercise records are complete.
• Confirm who currently has access to company records and whether that would still work if a new adviser, buyer or investor needed to review them.

The consultation is about future relief, but the benefits of preparation are broader. Clean records make fundraising smoother, reduce the chance of disputes and help advisers answer questions faster. They also make it easier to see whether a planned transaction could unintentionally reduce eligibility later.

There is also a trade-off worth being honest about: tidy records take time. For a busy founder, that can feel like back-office work that does not move the product forward. But compared with reconstructing ownership history years later, the effort is usually much smaller.

A common mistake is to treat this as a one-off compliance task. It is better understood as a living governance process. Whenever ownership changes, update the record set immediately. Whenever you raise money, grant options or reorganise the business, revisit the founder story and see whether the facts still line up.

1. 1

   Collect the core documents

   Pull together the cap table, incorporation documents, share certificates, board minutes, option paperwork, shareholder agreements and any side letters.

2. 2

   Write the ownership story

   Create a short timeline of what happened, when it happened and why. Keep it factual and dated.

3. 3

   Check for mismatches

   Compare the timeline against filings and legal documents. Resolve inconsistencies now, while the issues are still small.

4. 4

   Review likely future events

   Ask what could change ownership before exit: new funding, option grants, reorganisation or secondary sales.

5. 5

   Speak to the right adviser

   If the company is preparing a raise, restructuring or eventual sale, ask a tax adviser and solicitor to review the ownership position and the transaction plan together.

If you are also planning a product change, a systems rebuild or a data cleanup, this is a good moment to tidy the company records that sit behind those decisions. Founders’ Relief may be a tax consultation, but the preparation is mostly about clarity, control and future flexibility.
