You have built your agency over years. Maybe a decade. You have a retainer book that pays the bills, a team you trust, and a brand that means something in your sector. Now a buyer is interested. The offer letter arrives, and it says something like "consideration for the business and assets." Or maybe it says "100% of the issued share capital."
That distinction is the difference between a share sale vs asset sale agency exit. It is one of the most consequential decisions you will make as a founder. Get it right, and you keep more of the sale proceeds. Get it wrong, and HMRC takes a larger slice than necessary.
This article explains both routes, how they affect your tax position, what buyers typically want, and how to position your agency before you start negotiations.
What Is a Share Sale?
A share sale is exactly what it sounds like. The buyer purchases the shares in your company from you, the shareholder. Your agency continues to exist as a legal entity. The buyer simply takes over ownership.
From a legal standpoint, the company itself does not change. Its contracts, its liabilities, its tax history, its employment relationships all remain in place. The buyer steps into your shoes as the owner.
For you as the seller, a share sale means you are selling your ownership stake. You receive the proceeds personally. The company does not receive any money from the transaction.
Tax Treatment of a Share Sale
This is where the share sale vs asset sale agency exit comparison starts to matter in real pounds.
Share sales are treated as disposals of a capital asset. You pay Capital Gains Tax on your profit (the difference between what you paid for the shares and what you sold them for).
For most agency founders, the shares were acquired at incorporation for a nominal value. Perhaps £100. If you sell for £1 million, your gain is £999,900.
If you qualify for Business Asset Disposal Relief (BADR), formerly known as Entrepreneurs' Relief, you pay 18% on the first £1m of gains. That is a lifetime limit. Above £1 million, you pay 24% as a higher rate taxpayer.
Let us run the numbers on a typical agency exit.
Example: A 15-person digital agency based in Manchester Northern Quarter. Turnover of £1.2 million. Net profit of £280,000. Sale price agreed at 4.5x maintainable earnings, so £1.26 million. The founder owns 100% of the shares, acquired for £100.
Under a share sale with full BADR qualification:
- Gain: £1,259,900
- first £1 million at 18%: £100,000 tax
- Remaining £259,900 at 20%: £51,980 tax
- Total CGT: £151,980
- Net to founder: £1,108,020
That is a strong outcome. Over £1.1 million in your personal bank account after tax.
What Is an Asset Sale?
An asset sale is different. The buyer does not purchase the company. They purchase specific assets from the company. Goodwill, client contracts, intellectual property, the brand name, maybe some equipment. The company itself stays with you.
After the sale, the company is left as a shell. It has cash from the sale but no trading activity. You then need to extract that cash, typically by winding up the company and distributing the proceeds to shareholders as a capital distribution.
Asset sales are far more common when the buyer is a larger agency looking to bolt on your client base without taking on your company's history. They want your retainer book and your team. They do not want your old supplier agreements or the potential for a historic tax investigation.
Tax Treatment of an Asset Sale
Here is where the share sale vs asset sale agency exit comparison gets more complex.
When the company sells its assets, it pays Corporation Tax on the gain. The rate is 19% for profits up to £50,000, with marginal relief up to £250,000, and 25% above that. Most agencies selling for a decent sum will hit the 25% rate.
The company then holds the after-tax cash. To get that cash to you personally, you need to extract it. If you take it as a dividend, you pay dividend tax at up to 39.35%. If you wind up the company and claim capital treatment, you can get 18% under BADR on the distribution, but only if you meet the conditions.
Example: Same agency. Same £1.26 million sale price. But structured as an asset sale.
- Company sells assets for £1.26 million. Assume the assets have negligible base cost.
- Corporation Tax at 25%: £315,000
- Cash left in company: £945,000
- Company wound up, distribution to founder.
- Capital distribution of £945,000. BADR applies (assuming conditions met).
- first £1 million at 18%: £94,500 tax
- Net to founder: £850,500
That is £257,520 less than the share sale. A quarter of a million pounds difference because of the structure.
And that assumes BADR applies to the distribution. If you have already used your £1 million lifetime limit, the rate jumps to 20% (or 24% from April 2025).
Why Buyers Prefer Asset Sales
You might read those numbers and think "share sale every time." But it is not that simple. Buyers have their own incentives, and they often push hard for an asset sale.
Here is why.
Clean break from liabilities. In an asset sale, the buyer takes only what they choose. They do not inherit the company's past. No historic tax risk, no old employment tribunal claims, no supplier disputes. The seller's company retains all liabilities.
Step-up in tax basis. The buyer can allocate the purchase price to specific assets and depreciate them for tax purposes. Goodwill can be amortised over time, reducing future taxable profits. In a share sale, the buyer gets no such step-up. The company's tax base stays the same.
Selective hiring. The buyer can choose which employees to take on. They do not have to keep everyone. TUPE (Transfer of Undertakings) protections still apply to the transferring employees, but the buyer can decide which roles to offer.
These advantages mean buyers often offer a higher price for an asset sale than a share sale, because they see better value. The question is whether the premium is enough to offset your tax disadvantage.
When a Share Sale Works Best
A share sale is almost always better for the seller from a tax perspective, provided you qualify for BADR. But it requires the buyer to be comfortable taking on your company's history.
Share sales work best when:
- Your agency has clean financial records and no skeletons.
- You have a strong balance sheet with minimal debt.
- The buyer is a smaller agency or an individual who does not mind inheriting the entity.
- You have not used your BADR lifetime limit.
- Your agency has been trading for at least two years (the BADR holding period).
If you are selling to a larger group, they will almost certainly want an asset sale. That is where negotiation matters. You need to understand the trade-off and price accordingly.
When an Asset Sale Makes Sense
Sometimes an asset sale is the better route, even for the seller.
Consider these scenarios:
You have already used your BADR allowance. If you have sold a previous business and used the £1 million limit, your share sale gains above the allowance are taxed at 20%. The difference between 20% and the effective rate on a properly structured asset sale plus liquidation may be smaller than you think.
The buyer is offering a significant premium for an asset sale. If they offer 20% more because they value the tax step-up, the extra proceeds can offset your higher tax bill. Run the numbers both ways before deciding.
Your agency has contingent liabilities. Maybe you have a contractor who is challenging their IR35 status. Or a client dispute that could turn into a claim. An asset sale lets you leave those risks behind in the company, which then winds up after the liabilities are resolved or time-barred.
You want to retain some assets. Perhaps you own the office freehold through the company and want to keep it. An asset sale lets you sell the trading business while retaining the property.
