Why IR35 matters for locum doctors

Locum income is not automatically outside IR35 just because it is paid to a company.

The IR35 position depends on the real working relationship. The contract matters, but HMRC will also look at what happens in practice: who controls the work, whether substitution is genuine, whether there is ongoing obligation, and whether the doctor is operating like an independent business.

Public sector

NHS and public sector engagements often put status decisions on the engager.

Where the off-payroll rules apply, the client or fee-payer may decide whether the contract is inside or outside IR35 and whether PAYE/NIC should be deducted before payment.

Private sector

Private hospitals and clinics can create different responsibility chains.

The position may depend on the size of the client, agency chain, status determination process and whether the locum doctor works through a personal service company.

Company income

Inside IR35 income paid to a company needs careful accounting treatment.

Where PAYE has already been deducted from deemed employment income, the company and personal tax return position should be reconciled to avoid double counting or incorrect dividends.

The IR35 review route

We check the contract, the working practices and the tax treatment together.

A proper IR35 review should not rely on one clause or one CEST answer. The contract, day-to-day working arrangements, payment chain and tax treatment all need to align.

NHS body, agency, private hospital, clinic, end client and fee-payer position.

02

Contract review

Inside IR35 and company income

When inside IR35 income reaches your company, the accounts need careful treatment.

A common issue for locum doctors is that income may be paid to the company after PAYE and NIC deductions have already been applied by the fee-payer. That does not mean the company can treat the same funds in the same way as ordinary trading income without reviewing the tax treatment.

We check whether the income has already been taxed as deemed employment income, how it should appear in the company records, whether expenses or salary entries need adjustment, and how the director’s Self Assessment return should reflect the position.

Records needed

What we usually need for an IR35 review.

The exact records depend on whether you are reviewing a future contract, an active engagement, company income already received or an HMRC enquiry.

Contract

Agency contract, client contract, assignment schedule and any status determination statement issued by the engager or agency.

Working facts

Rota arrangements, supervision, substitution position, location, equipment, cancellation terms and practical control during the engagement.

Payment chain

Invoices, remittance statements, PAYE deductions, agency statements and company bank entries showing how income was paid.

Company records

Company accounts, payroll, dividends, Corporation Tax returns and director loan account records where income was paid to a PSC.

HMRC/CEST

CEST output, HMRC letters, client reasoning and correspondence where a status decision or compliance check is involved.

How we work

A clear process for reviewing IR35 risk and tax treatment.

We start with the contract and working facts, then review the payment chain and tax reporting position before advising on next steps.

Scope the engagement

We identify the client, agency chain, contract period, payment route and whether a status determination exists.

Review contract and practice

We compare written terms with the actual working arrangements, including control, substitution and mutuality.

Assess tax treatment

We review whether the income is inside or outside IR35, and how the company and personal tax position should be handled.

Advise or respond

We prepare written advice, tax return treatment, company accounts adjustments or HMRC response as agreed.

IR35 FAQs

Common IR35 questions from locum doctors.

These answers are general guidance only. The correct position depends on the contract, working practices, client, payment chain and tax year.

Does IR35 apply to locum doctors?

It can. IR35 may be relevant where a locum doctor provides services through a limited company or other intermediary and the direct relationship would look like employment.

Who decides if a contract is inside IR35?

For public sector and medium or large private sector clients, the engager will usually have responsibility for assessing the status. For small private sector clients, the contractor’s company may still need to assess the position.

What happens if income is inside IR35?

The fee-payer may deduct PAYE and employee NIC before paying the company. The company accounts and personal tax return then need to reflect the taxed income correctly.

Is a CEST result enough?

CEST can be useful, but the result depends on the facts entered. We review whether the answers match the contract and actual working practices.
