Who this is for: For founders who are in early conversations about an MBO and want to understand the tax structure before agreeing a price or a timeline.
A management buyout is one of the most common exit routes for founders of privately held businesses. The management team knows the business. The transition is smoother than a trade sale. The price is often lower than a strategic buyer would pay.
The tax structure of an MBO determines how much of the agreed price the founder actually receives. A £5m MBO at 20% CGT leaves the founder with £4m. The same MBO structured with BADR leaves the founder with £4.5m. Structured with SSE via a holding company, the founder receives the full £5m.
The three tax outcomes
The tax outcome of an MBO depends on three factors: whether the founder holds shares personally or through a holding company, whether the qualifying conditions for BADR or SSE are met, and how the consideration is structured (upfront, deferred, or earnout).
Personal shareholding, no BADR: CGT at 20% on the full gain. On a £5m gain, £1m to HMRC.
Personal shareholding, BADR qualifying: CGT at 10% on the first £1m of gains, 20% on the remainder. On a £5m gain, approximately £900,000 to HMRC.
Holding company, SSE qualifying: No CGT on the disposal. On a £5m gain, £0 to HMRC.
Deferred consideration and earnouts
MBOs frequently involve deferred consideration: a portion of the purchase price is paid over time, contingent on future performance. The tax treatment of deferred consideration depends on whether it is structured as a capital payment (CGT) or an income payment (income tax at 45%).
An earnout structured as employment income is taxed at 45% plus NICs. The same earnout structured as a capital payment is taxed at 20% CGT (or 10% with BADR). The difference on a £1m earnout is approximately £250,000.
The price is agreed at heads of terms. The tax structure must be agreed before heads of terms. After that, it is too late.

The Structure Before the Price
The tax structure of an MBO is determined by the architecture that was in place before the management team made their offer, not by the negotiation at the point of sale. The Stability layer does not address this. The Growth layer (a holding company with the right share class structure and SSE eligibility) begins to.
The Expansion layer is the constitutional architecture that ensures the transaction is structured correctly from the outset: the holding company was properly constituted, the share classes were correctly designed, and the MBO mechanism was built into the architecture before the management team appeared.
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.
