At some point, the shape of a company stops fitting. A shareholder wants out. A management team is ready to step up. Assets have piled up that no buyer wants to inherit. Or the group structure has quietly grown into something no one can properly explain.
Restructuring is often the answer, but the tax consequences of getting it wrong can be brutal. Here’s a plain-English look at five of the most common scenarios and what to watch out for.
1. Share Buybacks: When a Shareholder Wants Out
A company purchase of own shares is the go-to when one shareholder needs to exit and the others want to carry on. Typical triggers include disputes, retirement, divorce, death, or tidying up the share register before a sale.
It’s the simplest route because no new companies are involved and stamp duty is only half a percent. But it’s also the hardest to qualify for. The exiting shareholder wants capital gains tax treatment, and HMRC’s conditions are strict: five years of ownership, at least a 25% reduction in their holding, and a genuine benefit to the trade. The company also needs distributable reserves.
Advance clearance from HMRC is available, and worth getting. The critical thing is that the paperwork must be done properly under the Companies Act. Get it wrong and the whole thing is void, which only tends to surface years later during a sale, by which point it’s a serious mess.
2. Holding Company Restructures: When There Aren’t Enough Reserves
If you need to buy out a shareholder but the company doesn’t have the reserves for a standard buyback, a holding company structure is usually the answer. You put a new company on top of the trading company, and the funding flows through the group rather than out of trading reserves in one go.
The plus side is flexibility. Ongoing shareholders can roll their shares over tax-free. The 25% reduction test is less strict, so family shareholders wanting to keep a meaningful stake can often still qualify for capital gains treatment.
The downsides are more stamp duty (charged on the full company value, not just the exiting slice), the cost of running an extra company, and a trading company balance sheet that looks untidy while the intercompany loan is paid down. When a straight buyback isn’t possible, though, this is usually the right move.
3. Management Buyouts: Rewarding the People Who Know the Business
If you’re stepping back and there’s no family successor or obvious external buyer, your management team may be the answer. It works particularly well for niche businesses that are hard to value externally, or where you want to reward a team who already runs the day-to-day.
Funding is the trickiest part. The deal usually gets structured with a mix of cash, third-party debt, deferred consideration, preference shares, and rolled-over ordinary shares.
One tool worth knowing about is EMI share options. Lenders usually want the management team to have real skin in the game, but asking a manager to find £50,000 for shares often isn’t realistic. EMI options let you give them ownership at a discount without an upfront cost or unexpected income tax charges later. Valuations still matter, though. Giving shares away below true market value can land your management team with a nasty tax bill, which isn’t the reward you had in mind.
4. Capital Reduction Demergers: Splitting a Company in Two
Sometimes the answer isn’t buying someone out. It’s separating the business into two.
You’ve built a successful trading company, and over the years the profits have been invested in property, cash, or other assets that a buyer has no interest in. The buyer wants the trade, not the property portfolio. Selling everything and buying back what you want to keep would trigger huge tax bills.
A demerger lets you separate the trade from the investments without triggering stamp duty, capital gains tax, income tax, or corporation tax. On a £10 million business made up of £6 million of trade and £4 million of properties, you sell the £6 million and pay capital gains tax only on that. The £4 million of properties stays with you, untouched.
The mechanics are involved and the fees aren’t small. But they’re always cheaper than the tax you’d pay by trying to do it any other way.
5. Cleaning Up: Getting Rid of Unwanted Subsidiaries
Most groups end up with subsidiaries that no longer serve any purpose. They still cost money, still need filings, still carry hidden risks. Buyers don’t want to inherit a group full of loose ends.
There are two ways to deal with them. A members’ voluntary liquidation is the formal route, costing around £6,000 to £7,000, and definitively kills off the company along with any latent risks. Useful for old trading entities where claims could surface years later.
For companies with no real risk attached, striking off is much cheaper. You tidy up the balance sheet, waive any intercompany balances, and send a small fee to Companies House. If anything unexpected does emerge later, the company can be restored.

Restructuring isn’t the kind of work you want to figure out from a blog post, however useful the overview. Every company is different, and the tax treatment turns on details that only come out in a proper conversation.
A qualified accountant who handles restructures regularly can model the tax outcomes and get HMRC clearances lined up before you commit. Firms like Bevan Buckland work with owner-managed businesses across South Wales and beyond on exactly these kinds of transactions.
The earlier you start the conversation, the more options stay open.
