The change follows the tribunal decision in Isle of Wight NHS Trust and others, dealing with the scope of the exemption for the provision of a deputy for a registered medical practitioner. Historically, HMRC took a restrictive view and commonly treated agency-supplied locum doctors as taxable staffing supplies.

HMRC has now accepted that its position needs to be revised. In practical terms, that opens the door for some businesses and healthcare providers to review whether VAT was overdeclared on qualifying locum doctor supplies.

That does not mean every medical staffing arrangement is automatically exempt. It means the old blanket approach is no longer safe, and the underlying arrangements need to be analysed properly.

The opportunity may be relevant to:

• employment businesses and agencies supplying locum doctors
• NHS bodies and private healthcare providers who have paid irrecoverable VAT on locum doctor costs
• medical businesses reviewing historic VAT treatment across multiple contracts or divisions
• groups with partial exemption issues where input tax recovery may also need to be revisited

The commercial position differs depending on where you sit in the supply chain. A supplier considering a refund claim has different issues from a healthcare body which historically bore the VAT cost.

Although the headlines suggest a refund opportunity, the position is rarely as simple as filing a correction and waiting for repayment.

Key issues often include:

• whether the supplies actually fall within the exemption on the facts
• whether any benefit must be passed back under the commercial contract
• whether HMRC may raise unjust enrichment arguments
• whether previously recovered input tax needs to be adjusted
• whether customers’ historic VAT positions need to be reworked

This is why specialist commentators have described HMRC’s revised stance as more than a minor tweak — it has the potential to unlock refunds, but also to trigger knock-on adjustments across the supply chain.

If you are a medical recruitment agency, an NHS trust, or a private healthcare provider that routinely uses locum doctors, it is worth exploring this now — not at year end. These claims are time-limited, evidence-driven and often require a structured approach to documentation, contracts and VAT mechanics.

Just as importantly, HMRC guidance is still evolving. The strongest claims tend to be the ones that are properly evidenced, correctly scoped and aligned with the commercial reality of how supplies were made.

Shipleys Tax advises healthcare organisations and medical staffing suppliers on complex VAT issues, including eligibility reviews, quantification, claim strategy, and the knock-on effects on partial exemption and contracts. We focus on building claims that are commercially sensible and technically robust — and we manage the process so you don’t end up creating a second problem while trying to fix the first.

Where appropriate, we can help with:

• reviewing whether the supplies are capable of exemption
• quantifying historic overdeclared VAT
• assessing unjust enrichment risk
• reviewing contracts and pass-through clauses
• considering partial exemption and input tax consequences
• preparing a measured claim and disclosure strategy
