A managed service company (MSC) is a contractor’s company that is in practice run by a scheme provider rather than by the contractor. Under Chapter 9 of Part 2 of ITEPA 2003, every payment the worker receives through an MSC is taxed as employment income through PAYE with Class 1 National Insurance, and if the company does not pay, HMRC can transfer the debt to its directors, to the MSC provider and, in some cases, to others who pushed the worker into the arrangement.

What makes a company a managed service company?

The MSC rules took effect on 6 April 2007 and were aimed at composite companies and managed personal service companies, where a provider supplies the structure and the worker, although a shareholder, does not really control the company (HMRC Employment Status Manual, ESM3505). Section 61B(1) ITEPA 2003 sets four conditions, and all four must be met:

  1. the company’s business consists wholly or mainly of providing, directly or indirectly, the services of an individual to other persons;
  2. payments are made to the individual, or associates, equal to the greater part or all of the consideration for those services;
  3. the way those payments are made leaves the individual with more, net of tax and National Insurance, than if every payment had been employment income; and
  4. a person who carries on a business of promoting or facilitating the use of companies to provide the services of individuals (an MSC provider) is involved with the company.

HMRC applies the second and third tests cumulatively each time the worker is paid (ESM3510): receipts of £500 and £400 against payments of £300 and £250 give £550 out of £900, still the greater part. An umbrella company that pays everything as salary through PAYE fails the third condition, so it is not an MSC.

Who counts as an MSC provider?

The provider must carry on a business of promoting or facilitating companies that provide the services of individuals, not companies generally. ESM3515 treats general accountancy firms, formation agents and payroll bureaux as outside it. A firm of accountants that has a discernible part of its business marketing corporate solutions to contractors is a provider for that part.

Section 61B(3) excludes a person merely because they provide legal or accountancy services in a professional capacity, and section 61B(4) excludes an employment business that only places individuals with clients. That agency exclusion is lost under section 61B(5) if the agency influences or controls how the worker is paid, gives an undertaking to make good tax losses, or influences the company’s finances beyond simply placing the worker. HMRC also warns that a professional qualification does not by itself stop someone being a provider (ESM3505).

When is a provider involved with the company?

Section 61B(2) says a provider, or an associate of the provider, is involved if it:

  • benefits financially on an ongoing basis from the provision of the worker’s services;
  • influences or controls the provision of those services;
  • influences or controls the way payments to the worker are made;
  • influences or controls the company’s finances or any of its activities; or
  • gives or promotes an undertaking to make good any tax loss.

ESM3520 gives indicators that HMRC treats as involvement in all circumstances: supplying a standardised corporate package, acting as director or company secretary of client companies, running the company bank account, and charging fees by reference to the number of invoices raised or payroll runs. Offering insurance against tax liabilities under the MSC rules, IR35 or any other tax provision also counts. Formation, returns and payroll work are not involvement if they follow tailored advice rather than a standard product. Where a provider sells a clearly standardised product, HMRC starts from the view that all its client companies are MSCs, and the onus is on each company to show otherwise.

How is the worker taxed once the rules apply?

Under section 61D, any payment or benefit the worker or an associate receives, from any person, that can reasonably be taken to be for the services, and that is not already earnings paid directly by the MSC, is treated as a deemed employment payment made by the MSC at the time it is received. HMRC stresses at ESM3530 that the label does not help: a fee, loan or advance is still caught.

Section 61E sets the calculation:

  1. take the amount of the payment or benefit;
  2. deduct expenses met by the worker that would have been deductible if the worker had been employed by the client; if the result is nil or negative there is no deemed payment;
  3. treat the remainder as including employer National Insurance and strip that out; what is left is the deemed employment payment.

Section 61G then applies PAYE as if the worker were employed by the MSC and bars further deductions from the deemed payment. ESM3570 treats all engagements as a single employment with the MSC, and ESM3535 warns that travel and subsistence costs that only put the worker in a position to work for a particular end client are not allowable. An MSC based overseas is treated by section 61G(7) as having a UK place of business where the worker is UK resident and the services are provided in the UK.

The detailed steps are compared with the IR35 version in the deemed employment payment calculation.

How do the MSC rules sit alongside IR35 and the off payroll rules?

If a company would be caught by the IR35 rules in Chapter 8 and also meets the MSC definition, the MSC rules apply instead (ESM3605). Where the off payroll rules in Chapter 10 also apply, Chapter 10 takes precedence: section 61D(4A) switches off the MSC charge where the client is a public authority, or is medium or large with a UK connection (see also ESM10004). In practice the MSC rules now bite mainly where the end client is a small private sector business; see small clients and the off payroll rules and the wider guide to IR35 and the off payroll rules. A business already treated as the employer under Chapters 7 to 10 is also outside the 2026 umbrella company rules (ESM2415), covered in umbrella companies and tax.

When can the debt pass to directors and providers?

Section 688A ITEPA 2003, with regulations 97A to 97X of the Income Tax (PAYE) Regulations 2003 and the Social Security Contributions (Managed Service Companies) Regulations 2007, lets HMRC recover an MSC’s unpaid PAYE and Class 1 National Insurance from:

  • a director, other office holder or associate of the MSC;
  • the MSC provider;
  • any person who directly or indirectly encouraged, or was actively involved in, the provision of the worker’s services by the MSC; and
  • a director, office holder or associate of a provider or of such a person.

Section 688A(3) excludes anyone merely providing legal or accountancy advice in a professional capacity, and anyone merely placing the worker with clients. HMRC’s process at ESM3635 starts with a formal debt, often a regulation 80 determination, followed by a demand to the MSC giving seven days to pay. ESM3620 treats three months as a reasonable time for recovery from the company, and the company does not need to be in liquidation before a transfer is considered.

The time limits are strict. A transfer notice to a director or other officer of the MSC, or to the provider and its officers, must be issued within twelve months of the debt becoming due. The wider third category (people who encouraged or were actively involved) can be pursued only for debts incurred after 6 January 2008, only once an officer has certified that recovery from the first two categories is impracticable, and within three months of that certificate (ESM3625 and ESM3635). HMRC limits these notices to people who encouraged the worker in or played an active part, and who knew it was an MSC or failed to take reasonable steps to check. A worker shareholder is normally treated as within this category. A notice can be appealed to the First tier Tribunal within thirty days (ESM3640), the debt remains a PAYE debt (ESM3645), and a transferee who pays cannot deduct the payment for tax.

What does this look like in practice?

Illustration only. Provider P sells contractors a ready made company package. P’s staff act as company secretary, P operates the company bank account, charges £100 for every invoice raised and pays each contractor a small salary with the rest as dividends. Sam’s company receives £6,000 a month from an agency and pays Sam £500 salary and £4,500 dividends. All four conditions are met, so each dividend is a deemed employment payment. The company makes no PAYE return on the dividends and has no assets. HMRC issues a regulation 80 determination and a demand, then within twelve months sends transfer notices to Sam as director and to P as provider. The agency that simply placed Sam’s company is excluded, unless it had required Sam to use P, which ESM3610 says could bring it within the transfer rules.

What mistakes do contractors and advisers make?

  • Assuming that calling a business an accountancy practice protects it. The test is what the firm actually does for contractor clients.
  • Moving the bank account or incorporating new companies in the worker’s name without changing who really decides. HMRC looks beyond structural changes and documentation (ESM3520).
  • Labelling extraction as loans or advances. Section 61D catches any payment or benefit for the services.
  • Directors ignoring the personal exposure. A worker who is a director of the MSC is in the first category for a transfer notice; see also directors’ tax responsibilities.
