The ruling, which was handed down in April, found Costelloe Business Services, a firm that set up and ran limited companies for hundreds of agency social workers and more than 200 health professionals, fell foul of strict tax rules in the way it worked (see box below).

Costelloe was found to be caught by ‘Managed Service Company’ (MSC) legislation introduced in 2007, which meant practitioners’ earnings should have been subject to full PAYE tax charges.

HMRC expects to recover up to £9m from Costelloe’s operation. Yesterday, Community Care revealed social workers have been hit by retrospective tax bills of up to £45,000 each as HMRC has used legal powers to claw back unpaid taxes from Costelloe-run companies by transferring debts on to individual practitioners who were their directors.

Tax consultants told Community Care HMRC is targeting other companies that operate similarly to Costelloe Business Services. They recommended social workers set up as limited companies should review their arrangements in light of the ruling.

Kye Burchmore, a director at Assured Tax Consulting, said: “Costelloe is not a one off. There are many companies that operate in a similar way although they will all say they operate slightly differently or don’t get quite as involved. But in my opinion, it is a slippery slope and while it may be true of some, HMRC are currently targeting others under this legislation and I believe other companies will also fall foul of this law.

“For people looking at setting up limited companies, or being pushed in that direction, the main thing is to engage a genuine accountancy practice to assist you in this process – which will maybe provide you with a little advice about structuring your pay and dividends and do your accounts, but nothing more.

“There is an exemption that means if a company provides legal or accountancy services in a professional capacity, they will not fall within the [MSC] rules. This was not, rather surprisingly, argued in the Costelloe case but even if it had been, I feel the judge would have quickly said they went far beyond just providing accountancy services.”

David Kirk is a tax consultant who specialises in employment status, PAYE and National Insurance. Asked what advice he would give to social workers considering setting up as a limited company in light of the Costelloe ruling, Kirk said: “By and large – don’t. I’d look at each proposition on its merits, but how many social workers have the skills and competence to run a company? They are not exactly the same sort of skills one requires for doing social work.

“You can do it if you take advice from accountants, but it has to be that: advice. If you let accountants, or providers, or whatever they call themselves, run your company for you, then you may well be in Managed Service Company territory and you are unlikely to know enough about how the provider works to be able to tell – it is the provider’s behaviour that really determines this, not yours.

“Even if you think you can, you’re not out of the woods. You still have to consider the intermediaries laws, commonly known as IR35. These basically ask, ‘If your company and the agency weren’t there, would you be an employee of the local council for whom you are working?’ In other words, it looks at the underlying reality. I suspect that there are few social workers who would have the knowledge and confidence to answer ‘no’ to that.”

Costelloe Business Services’ now defunct website boasted that the firm’s “commitment, experience and attention to detail will ensure that your company and its accounts are compliant with Companies House and HMRC regulations”.

Crawford Temple, chief operating officer at Professional Passport – a company specialising in compliance in the contractor sector – said practitioners should be careful to seek further advice on such assurances.

He said: “The key thing for any contractor is that they should get independent third party validation of a provider’s compliance if they are being recommended to use anyone. Because the issue is every single provider maintains they are compliant, the reality is some are not.

“The common line is ‘If something looks too good to be true, it probably is.’”
