What is a management buyout for tax purposes?
Answered 17 March 2026
There is no specific statutory definition of a "management buyout" in UK tax legislation — it is a commercial/structural concept described in HMRC guidance. The available sources do not contain a legislative definition, so the answer draws entirely from HMRC guidance.
HMRC guidance / practice
A management buyout (MBO) is a transaction in which some or all of the existing management team of a target business purchase a significant share in the ownership of that business from its existing shareholders.
Key structural features
- Management typically acts with the assistance of a private equity backer.
- A new company ("Newco") is created specifically as the acquisition vehicle to acquire the shares of the target company.
- The overall financing package relies heavily on debt ("leverage"), which is why MBOs are also called leveraged buyouts (LBOs).
Typical funding structure
Buyouts are typically funded through a mixture of:
- Third-party debt (e.g. from banks or specialist lenders) — usually the "senior debt" with the best security;
- Shareholder debt (from the private equity fund and/or management team); and
- Equity (e.g. ordinary shares).
A further subordinated slice of debt, ranking below senior debt but above equity, is referred to as junior or mezzanine debt and carries a higher interest rate to reflect its greater risk.
Worked example
HMRC illustrates a typical MBO as follows: a company available for £40m is acquired by senior managers backed by a venture capitalist (VC). A Newco is formed, funded by bank senior debt (£25m at 7%), mezzanine debt (£5m at 10%), VC preference shares and subordinated debt, and ordinary shares split 85% VC / 15% management. The managers invest £300,000 of their own money for 15% of the ordinary shares. Customary leaver provisions (requiring managers to sell shares, possibly at below market value, on leaving employment) and drag-along/tag-along provisions are included.
Relevance to specific tax rules
- For Share Incentive Plan (SIP) purposes, an MBO can constitute a "general offer" even where shares held by participating managers are subject to separate agreements.
- For capital/revenue purposes, a payment made in an MBO to acquire a business (including goodwill and associated agreements) is treated as a capital payment and is not deductible as a revenue expense.
Note: There is no single statutory definition of "management buyout" in UK tax law. The concept is a commercial one, and its tax treatment depends on the specific transaction structure and the tax provisions engaged (e.g. transfer pricing, employment-related securities, loan relationships, CGT, etc.).

Many private equity backed acquisitions are achieved through a management buyout (MBO). In an MBO some or all of the existing management team of the target business purchase a significant share in the ownership of the business from existing shareholders. Often, management will do this with the assistance of a private equity backer. Private equity funds use a combination of their own funds, funds from the management team and debt to fund a separate company (a new company created for the purpose)
ions of four Law Lords. The views set out above received more recent support from the Special Commissioners in Triage Services Ltd v CIR [2006] SPC 519. In a management buyout, Triage took over activities formerly undertaken by another company. Triage paid £8m for the business and under a separate ‘repairs’ agreement the vendor agreed to offer Triage work commanding gross fees of £63m over the coming seven years, with provision for compensation if this did not happen. There was evidence that the
A general offer must satisfy two conditions (Section 498(10)): it is made to holders of shares of the same class as the participant’s Schedule 2 SIP shares or to holders of shares in the same company; and it is made in the first instance on a condition such that, if satisfied, the offeror will control the company within the meaning of section 450 and 451 CTA2010. An offer will be a general offer for these purposes even if it is made to different shareholders by different means (Section 498(11)).
5.1 The following hypothetical example sets out how the above approach may be applied to a typical management buyout. A company is available to be purchased for £40m. The senior managers of the company obtain the backing of a VC to buy it in a management buyout. A new company (‘Newco’) is formed as the vehicle to acquire it. Newco is to be funded by the management team, the VC and banks. The managers and VC determine that the company needs £8m of expansion capital to develop its business, and th
