Who this is for: Founders who are in early discussions about a management buyout and have not yet reviewed how the holding structure affects the tax treatment of rolled equity and loan notes.
You sold to your management team. It felt like the right outcome: the people who had helped build the business would own it. You rolled some equity to maintain a stake in the upside. You carried back loan notes for part of the consideration. The deal felt friendly and well-structured.
The tax treatment was not what you expected.
The April 2026 MBO tax rates
From April 2026, both trade sales and management buyouts are taxed at 18% to 24% on qualifying gains, depending on the size of the gain and whether Business Asset Disposal Relief applies. The rates are not dramatically different from a trade sale. The structural problem is not the rate on the initial transaction, it is where the rolled equity sits.
The rolled equity problem
Without a holding company, the equity you rolled sits in the trading company. You are still a shareholder in the business you thought you had left. Future gains on that rolled equity (when the management team eventually exits) will be taxed as a personal gain. Depending on the timing and the tax rules at that point, the rate could be higher than the rate you paid on the initial MBO.
More practically: you are tied to the business you thought you had exited. The loan notes create an ongoing financial relationship. The rolled equity creates an ongoing ownership relationship. The "friendly exit" has become a deferred transaction with uncertain tax consequences.
| Structure | Initial MBO tax | Rolled equity position | Future exit tax |
|---|---|---|---|
| No holdco | 18-24% on gain | In trading company | Personal CGT at prevailing rate |
| Holdco + SSE | £0 (SSE on subsidiary sale) | In holdco | Extracted at basic rate over time |
What a holdco structure would have achieved
A holding company installed before the MBO, with the qualifying period already running, would have allowed the holdco to sell the trading subsidiary under SSE: no corporation tax on the gain. The rolled equity would have sat in the holdco, not the trading company. The loan notes would have been received by the holdco and deployed as investment capital. Future extraction would have happened at basic rate, over time, at your discretion.
The structure that makes this possible must be in place before any buyer or management conversation begins. An MBO that is already in negotiation cannot be restructured mid-transaction without HMRC scrutiny.
The structure that protects the MBO must be in place before the conversation begins. Not during it. Not after the heads of terms are signed. Before.
Map Your Structure
If you are in early discussions about a management buyout, the audit will show you whether the holding structure is in place to protect the transaction - and what it costs if it is not.

The situations in this article are not edge cases. They are the default outcome for founders who operate without the architecture above their business. The audit maps your position in five minutes and tells you exactly which of these gaps apply to you.
The audit is free. The Discovery Call is a paid 30-minute working session. The £500 is credited in full against the Capital Architecture.
The Structure That Determines the Tax Treatment
The difference between an MBO taxed as capital and an MBO taxed as income is not determined at the point of the transaction. It is determined by the structure that was in place before the management team made their offer.
The Growth layer (a holding company with the right share class structure and SSE eligibility) begins to address this. The Expansion layer is the constitutional architecture that ensures the transaction is structured correctly from the outset, not retrofitted under time pressure once the buyer is at the table.
The founders who exit an MBO at capital gains rates built the right structure two to five years before the management team approached them. The ones who pay income tax rates built the right business but not the right architecture above it.
