If you own shares in your agency and you are thinking about selling up, the 2025 Capital Gains Tax rate changes have made BADR more valuable than ever. The main rate of CGT on business asset disposals rose from 10% to 18% for most assets in the 2025 Budget. But Business Asset Disposal Relief (BADR) still gives you a 14% rate on the first £1m of lifetime gains. That is a saving of £80,000 per million compared to the new main rate.
For BADR agency founders, the difference between qualifying and missing out is the difference between keeping £900,000 and keeping £820,000 on a million-pound exit. The rules have not changed. But the penalty for getting them wrong just got a lot bigger.
This article covers exactly what you need to do to qualify for BADR when selling your agency shares, with the 2025 rate changes baked into every calculation.
What BADR Actually Gives You (and What Changed in 2025)
BADR is the relief that reduces your Capital Gains Tax rate to 14% on qualifying disposals. Before April 2025, the main rate for most business asset disposals was also 10% for basic rate taxpayers and 20% for higher rate taxpayers. The difference was relatively small. That is no longer the case.
From the 2025 tax year:
- BADR rate: 14% on the first £1m of qualifying gains (lifetime limit)
- Main CGT rate for business assets: 18% (basic rate) and 24% (higher rate)
If you are a higher rate taxpayer selling shares worth £800,000, the difference is £112,000. That is not a rounding error. That is a school fees bill or a house deposit.
The lifetime limit of £1m has not changed. If you have already used some of your BADR allowance on a previous business sale, you need to track the remaining balance. Your accountant can check this from your previous tax returns.
The Five Conditions Every Agency Founder Must Meet
To qualify for BADR on your agency shares, you need to meet five conditions. Miss any one of them and the relief is lost on that disposal. There is no partial relief for "almost qualifying".
1. You Must Be a Director or Employee of the Agency
You need to be an officer or employee of the company at the time of disposal. This sounds straightforward, but it catches agency founders who have stepped back from day-to-day operations.
If you have moved into a non-executive role, or you are a silent shareholder, you do not qualify. You need to be on the payroll, or at minimum hold a director appointment, right up to the point of sale.
If you are planning an exit in 18 months and you currently draw no salary and hold no formal role, you need to fix that now. The two-year holding period starts from when you meet all conditions, not from when you acquired the shares.
2. You Must Hold at Least 5% of the Ordinary Share Capital
This is a hard threshold. 4.9% does not qualify. You need to hold at least 5% of the ordinary share capital and that 5% must give you at least 5% of the voting rights and 5% of the distributable profits.
If you have diluted your holding through investment rounds or an EMI scheme, check your current percentage. If you are at 4.8%, you cannot rely on BADR. You need to restructure or accept the higher rate.
If you are close to the threshold, speak to an ICAEW qualified accountant before you do anything. There are ways to reorganise share structures, but they need to be done well before the sale.
3. The Shares Must Be Held for at Least 24 Months
The two-year holding period runs from the date you meet all the qualifying conditions. If you became a director and acquired 5% of the shares on 1 March 2025, you can sell on or after 1 March 2027 and qualify.
If you acquired shares earlier but only became a director later, the clock starts from the later date. This is a common trap for agency founders who bring in a co-founder later in the business lifecycle. If the new co-founder only takes a director role six months after buying shares, their two-year clock starts from the director appointment date.
4. The Agency Must Be a Trading Company
This is where many agency founders get caught out. The company must be a trading company, meaning its activities are wholly or mainly trading in nature. If more than 20% of the company's assets are held for investment purposes, you lose BADR.
For a marketing agency or digital agency, this usually means:
- No large cash piles sitting in the company bank account for more than a few months
- No investment property owned by the company
- No significant passive income streams (licensing royalties, property rental, investment dividends)
If your agency has built up £400,000 in cash reserves and you are planning to sell, that cash is a problem. It counts as a non-trading asset. If it pushes your non-trading assets over 20% of total assets, you lose the relief.
The solution is usually to extract the cash as dividends before the sale, or to use it for trading purposes. But you need to do this at least a few months before the disposal, not the week before.
5. The Disposal Must Be of Shares (Not Assets)
BADR only applies to the disposal of shares in a trading company. If you sell the agency's assets instead of the shares, you pay CGT at the main rate. If you are a sole trader or partnership, you cannot use BADR at all.
Most agency sales are share sales, but some buyers prefer asset purchases. If a buyer insists on an asset purchase, you lose BADR. You need to negotiate this upfront or structure the deal differently.
How the 2025 Rate Changes Affect Your Exit Planning
The main CGT rate increase from 20% to 24% for higher rate taxpayers means the BADR saving is now 14 percentage points instead of 10. That changes the maths on when it is worth restructuring to qualify.
Before the rate change, if you were 0.5% short of the 5% shareholding threshold, the cost of restructuring might have outweighed the tax saving. Now the saving is larger. It is worth running the numbers again.
For a £1m gain, the difference between BADR and the main rate is £140,000. That covers a lot of legal and accounting fees.
Common BADR Traps for Agency Founders
These are the mistakes we see most often when BADR agency founders come to us after a deal has been signed. They are all avoidable.
Cash Build-Up Before Sale
Your agency has been profitable. You have built up a war chest. That cash is sat in a business current account earning no interest. When you sell, that cash is a non-trading asset. If it is more than 20% of your total assets, you lose BADR on the whole gain.
The fix: extract the cash as dividends before the sale, or reinvest it in trading activity. If you need the cash for working capital during the sale process, keep it under the 20% threshold and document the trading purpose.
Personal Service Companies That Have Grown
Many agency founders started as sole traders or limited company contractors. If you have built up a personal service company that now employs staff and serves clients directly, you are probably fine. But if the company still has significant retained profits from your contracting days, those profits can be classed as non-trading income.
If more than 20% of your company's income in the last 12 months came from non-trading sources (including dividends from other companies), you fail the trading test.
EMI Share Schemes and Dilution
If you have issued EMI options to key staff, your own shareholding may have dropped below 5% on a fully diluted basis. BADR is tested on the actual shares you hold, not the options. But if you have granted options that, when exercised, would take you below 5%, you need to plan the timing of the sale carefully.
What to Do Now (Before You Find a Buyer)
If you are planning to sell your agency within the next three years, here is your checklist:
- Confirm your shareholding percentage, check it is at least 5% of ordinary shares with full voting and profit rights
- Check your director status, make sure you are formally appointed and on the payroll
- Review your company's asset composition, calculate non-trading assets as a percentage of total assets. Keep it under 20%.
- Extract excess cash, dividend it out or reinvest it before the sale process begins
- Check your BADR lifetime allowance, if you have used BADR before, calculate your remaining £1m limit
- Plan the two-year holding period, if you do not yet meet all conditions, the clock starts from when you do
- Review your share structure, if you are close to the 5% threshold, consider a share consolidation or reorganisation

Can You Still Qualify If You Have Already Missed Some Conditions?
Sometimes. It depends on how far you are from meeting the conditions and how long you have before the sale.
If you are below the 5% threshold, you can restructure the share capital. But HMRC may challenge this if it is done too close to the sale. The general rule is that the restructuring needs to have genuine commercial substance, not just a tax avoidance motive.
If your company has too many non-trading assets, you can extract them. But if the assets are property or investments, extracting them may trigger a tax charge. You need to model the net benefit before acting.
If you are not a director or employee, you can appoint yourself. But the two-year clock starts from the appointment date. If you want to sell in 12 months, you are out of luck.
What Happens If You Do Not Qualify for BADR?
You pay CGT at the main rate: 18% on gains within your basic rate band, 24% on gains above that. For most agency founders selling a profitable business, the effective rate will be close to 24%.
On a £1.2m gain, that is £288,000 in tax instead of £120,000. The difference is £168,000.
There is no alternative relief that gives you a lower rate on the same disposal. Investors' Relief gives 10% on up to £10m of gains, but it requires a three-year holding period and has stricter conditions. It is worth checking if you qualify, but most agency founders do not.
