You build your agency for years. You get the offer. You're looking at a seven-figure exit. Then your accountant asks one question: "When did you acquire your shares?"
If the answer is less than two years before completion, your 10% tax rate disappears. You're looking at 20% capital gains tax instead. On a £2m sale, that difference is £200,000.
Business Asset Disposal Relief (BADR), formerly Entrepreneurs' Relief, gives you a 18% capital gains tax rate on qualifying disposals. The lifetime limit is £1m of gains. The rules are specific. And the 2-year holding period is the one that catches most agency founders off guard.
Here is exactly what you need to know, the traps that trip people up, and how to plan your exit around them.
What Is BADR and Why Does It Matter for Agency Founders?
BADR is a relief that reduces your capital gains tax rate from 20% to 18% when you sell shares in your trading company. For a digital agency founder selling their shares, this is the single most valuable tax relief available.
The relief applies to the first £1m of lifetime gains. Anything above that is taxed at the standard 20% rate. If you're selling a profitable agency with strong recurring revenue, you'll likely hit that £1m cap on your first exit.
To qualify, you must meet several conditions. The most commonly overlooked one is the 2-year holding period.
The 2-Year Holding Period Rule: Exact Requirements
For a disposal on or after 6 April 2019, you must have held the shares for at least two years before the date of disposal. That means two full calendar years from the date you acquired the shares to the date you sell them.
If you acquired shares on 1 March 2024, you cannot complete a qualifying disposal before 1 March 2026. A sale on 28 February 2026 would fail the test. The entire gain would be taxed at 20%.
This is not a "substantially all" test. It is a hard deadline. HMRC does not round up.
You also need to meet the other conditions throughout that 2-year period:
- You must be an officer or employee of the company (director or employee).
- You must hold at least 5% of the ordinary share capital and 5% of the voting rights.
- The company must be a trading company (or holding company of a trading group) throughout the period.
Most agency founders meet the 5% and employment tests easily. The trap is the timing.
The Trap That Disqualifies Most Agency Founders
Here is the scenario I see repeatedly. A founder starts their agency as a sole trader. After a few years, they incorporate. They issue themselves shares on incorporation. They trade for three years. They get an offer. They think they've held shares for three years.
They haven't. They held the business for three years. But they held the shares for three years. That is fine if they incorporated on day one.
But many founders incorporate later. Or they restructure. Or they issue new shares to bring in a co-founder. Or they transfer shares between group companies. Each of these events resets the holding period clock for BADR purposes.
Consider this real example. A creative agency founder started trading in 2018 as a sole trader. Incorporated in 2020. Issued shares to himself on 1 June 2020. Brought in a co-founder on 1 January 2022 by issuing new shares. Received an offer in November 2023. The co-founder had held shares for 22 months. The entire sale was delayed to March 2024 to hit the 2-year mark. The buyer walked. The founder lost the deal.
That is the trap. Not the rule itself. The failure to track the share acquisition date for every shareholder.
Common Events That Reset the Clock
These events can restart your 2-year holding period:
- Issuing new shares to new shareholders
- Transferring shares between group companies in a restructuring
- Converting share classes (e.g. ordinary to A ordinary)
- Acquiring shares through an EMI option exercise
- Inheriting shares
Each of these creates a new acquisition date. If you plan to sell within two years of any of these events, you lose BADR on those shares.
How to Plan Around the 2-Year Holding Period
The fix is simple in principle: plan your exit at least two years out from your last share acquisition event.
In practice, that means you need to think about BADR the moment you issue any new shares, not the moment you decide to sell.
Start the Clock Early
If you are a sole founder, incorporate on day one. Issue your shares immediately. Your 2-year clock starts on day one. If you sell in year three, you qualify.
If you are already trading as a sole trader, incorporate as soon as you can. Every month you delay is a month added to your holding period before you can sell with BADR.
Bring in Co-Founders Early
If you plan to bring in a co-founder, do it early. Issue their shares at least two years before any anticipated exit. If you are in acquisition talks and want to add a partner, you need to factor in the delay or accept that their shares will not qualify for BADR.
Some founders use EMI (Enterprise Management Incentive) options to give co-founders or key employees a stake. The BADR holding period for EMI shares starts from the date of grant, not exercise, provided the option is exercised within 90 days of leaving. That is a nuance worth discussing with your accountant.
Avoid Restructuring Before an Exit
If you are considering a holding company structure or a group reorganisation, do it well before you plan to sell. Every share transfer resets the clock. If you restructure 18 months before a sale, you lose BADR on the new shares.
We cover this in more detail in our guide on incorporation and structure planning for agency founders.
The £1m Lifetime Limit: How It Interacts With the Holding Period
BADR applies to the first £1m of lifetime gains. If you have used some of your allowance on a previous sale, you need to track your remaining capacity.
The holding period applies to each disposal separately. If you sell shares in tranches, each tranche must meet the 2-year test on its own. You cannot aggregate holdings across different companies.
For agency founders with multiple agencies, this is a common complication. If you own shares in two separate trading companies, each disposal is tested independently. You could sell one agency after 2 years and another after 3 years. Both qualify, but your combined gains are capped at £1m.
If you are running multiple agencies under a group structure, the holding company rules apply. The group must be a trading group. And each shareholder's holding period is measured from their acquisition of shares in the holding company.
What Happens If You Miss the 2-Year Window
You pay 20% CGT instead of 10%. On a £1m gain, that is £100,000 extra tax. On a £2m gain, the first £1 million is at 18% (if you have the full allowance) and the second £1 million is at 24%. Total tax: £100k + £200k = £300k instead of £200k.
There is no grace period. No HMRC discretion. If you are 1 day short, you fail the test.
The only exception is if you are selling due to ill health or death. In those cases, the holding period can be reduced to 12 months. But that is rare and requires specific evidence.
Practical Steps to Protect Your BADR Position
Here is what I recommend every agency founder does today, regardless of whether you are selling next year or in five years:
1. Confirm your share acquisition date. Check your incorporation documents, share certificates, and Companies House filings. Write down the exact date you acquired your shares.
2. Check all shareholders. If you have co-founders, investors, or employee shareholders, confirm their acquisition dates too. A single shareholder failing the test can complicate the entire sale.
3. Avoid unnecessary share movements. If you are within 2 years of a potential exit, do not issue new shares, change share classes, or restructure without first checking the BADR impact.
4. Plan your exit timeline. If your 2-year anniversary is 14 months away, you cannot sell before that date. Build that into your negotiation strategy with buyers.
5. Keep the company trading. BADR requires the company to be a trading company throughout the 2-year period. If you wind down operations or move to a holding structure, you risk losing the relief.
