Managed service companies and the 2007 MSC rules

A managed service company is one through which a worker provides services and receives most of the payment for them, but which is run by a provider rather than by the worker. The structure grew up after IR35: a provider set up companies in bulk, placed contractors in them as nominal shareholders and directors, and paid them through low salaries and dividends, with the IR35 question left to a rule HMRC could not enforce against thousands of companies at once. By 2006 the composite company market ran to tens of thousands of workers.

The 2007 legislation

The Treasury published Tackling Managed Service Companies with the December 2006 Pre-Budget Report, consulted until March 2007, and legislated in the Finance Act 2007 with effect from 6 April 2007. Where a company is a managed service company, everything paid to the worker is employment income: the IR35 test of the hypothetical contract no longer applies. Unpaid PAYE can be transferred from the company to its directors, to the provider and its directors, and from January 2008 to any other person who encouraged or facilitated the arrangement, which was designed to reach the agencies and clients that used them.

What happened

The composite providers moved their workers into umbrella employment or individual limited companies within weeks. The umbrella market took most of them, and the market for contractor accountancy that served individual companies took the rest. The archive's coverage from December 2006 through 2007 records the consultation, the industry's objections to the width of the definition, the concession for professional advisers and the transition.

The involvement test today

The rule turns on whether a provider is involved with the company: promoting the structure, influencing how payments are made, benefiting financially from the worker's services, or providing insurance against the tax rules. A person providing accountancy or legal services is not involved merely by doing so, but the line between advising and running the company has never been drawn clearly. HMRC's actions from 2022 against contractors served by particular accountancy firms, on the argument that the firm's involvement made every client company a managed service company, revived a rule the industry thought settled. The Freelancer and Contractor Services Association asked the Chancellor in its 2026 Budget submission to rewrite it.
