Problems we fix for locum doctors

  • "I don't know if I should be a sole trader, a limited company or use an umbrella."
  • "A trust or agency has sent me an IR35 determination I don't understand."
  • "My first tax bill was huge because of payments on account."
  • "I keep missing or getting my locum A/B and Type 2 pension forms wrong."
  • "I spend hours chasing unpaid invoices."
  • "I'm not sure what I can claim — indemnity, GMC, mileage?"
  • "Making Tax Digital quarterly updates start from April 2026 and I'm not ready."

What it's costing you

Leaving it unfixed is rarely free

Overpaid tax
Unclaimed expenses and wrong tax codes mean paying more than you owe, year after year.
HMRC penalties and interest
Late returns attract automatic penalties, plus interest on tax paid late.
Lost evenings
Hours spent on forms, invoices and spreadsheets after a long shift.

General examples — your position depends on your own figures.

What to know before you decide

Hospitals: Southampton General Hospital, Princess Anne Hospital

We act for locum doctors in Southampton working at Southampton General Hospital, Princess Anne Hospital. Many clinicians work across more than one of these sites or combine NHS posts with private lists, so we reconcile every payslip, bank or agency payment and private invoice into one return. Travel between work sites is usually allowable business mileage; travel from home to a regular workplace is not.

Commuter areas: Winchester, Chandler's Ford, Romsey, Hedge End

Clients often live in Winchester, Chandler's Ford, Romsey, Hedge End and travel in for shifts. Where you live does not change how you are taxed, but it can affect which journeys are allowable, whether a home office is a genuine workplace, and which local practices and clinics you take sessions at.

Locum and agency shifts, trust bank work, IR35 and MTD

NHS bodies must issue a Status Determination Statement for each off-payroll engagement. The decision turns on control, substitution and mutuality of obligation. Inside IR35 work is taxed like employment; outside work can be invoiced through a company. We review contracts, determinations and the effect on take-home pay.

IR35 Reviews for Doctors & Healthcare Professionals

Travel/mileage between sites

Allowable costs include HMRC-approved professional registrations and subscriptions, indemnity where you pay it, business mileage between workplaces and equipment used for work. Ordinary commuting and personal costs are not allowable. Employees claim through HMRC; the self-employed deduct costs in their accounts.

Local FAQs

How much tax does a locum doctor pay in the UK?

Locum doctor accountants · southampton pay income tax on taxable profit at 20%, 40% and 45%, plus Class 4 National Insurance on self-employed profit.

Should a locum doctor be a sole trader or a limited company?

A limited company can suit locum doctor accountants · southampton with substantial private or outside-IR35 income that is not all needed to live on, because profit is taxed at corporation tax rates and can be paid out over time. It brings extra accounts, payroll and filing costs, and NHS employment income cannot move into it. We model sole trader against limited company on your real figures first.

Is locum work through an agency or trust bank inside IR35?

For locum engagements with NHS bodies, the hirer must decide IR35 status and issue a Status Determination Statement; the small-company exemption does not apply to public bodies. The test looks at control, substitution and mutuality of obligation in the actual working arrangement. You can ask the hirer to review a determination you disagree with, and it must respond within 45 days.

You should set aside a portion of every invoice to cover Income Tax, National Insurance, and potential student loan repayments.

Regular monitoring ensures you have sufficient funds for these deadlines.

Why is my first tax bill as a locum so high (payments on account)?

Your first bill often includes the tax for the previous year plus the first payment on account for the following year. Payments on account are due on 31 January and 31 July. Each payment is normally half of the previous year's total tax liability. This can effectively result in paying 150% of your tax in one go.

Fixed fee quoted after a review

Discuss this package

Employment status is determined by the facts, not the package you choose. PAYE, umbrella and partnership arrangements may also apply. A limited company does not override IR35 or off-payroll rules, and not every employed clinician needs a tax return.

Overpaid tax?

Tax refund support for locums

We review tax codes, eligible professional expenses and overpaid tax, then prepare a claim where you qualify. A refund is not guaranteed; HMRC decides the claim.

£249 + VAT

For refunds up to £5,000, our fee is £249 plus VAT. For refunds above £5,000, add 5% of only the amount above £5,000 to the £249 fee. VAT applies to the total professional fee.

Example: a £6,000 refund means £249 + £50 = £299 plus VAT.
