NHS Locum Tax Returns in Scotland: A Guide for Bank and Agency Doctors

NHS locum doctors working in Scotland on bank or agency contracts must complete a self-assessment tax return each year. Their locum income is taxed at Scottish income tax rates — 42% higher rate above £43,662 and 45% advanced rate above £75,000 — and NHS pension growth may trigger an annual allowance tax charge. Managing these obligations correctly requires specialist knowledge of both Scottish tax and NHS pension rules.

Types of NHS locum income

• Bank shifts: paid by the NHS trust or health board directly, usually on PAYE.

• Agency placements: the agency pays through PAYE; the locum may receive a net amount.

• Sole trader locum income: if working outside IR35, income declared on self-assessment.

Scottish income tax on locum earnings

NHS locum income is non-savings income and is therefore taxed at Scottish rates. A doctor earning £80,000 from a combination of regular salary and locum work will have income taxed at the Scottish advanced rate of 45% on the portion between £75,001 and £80,000. Above £125,140 the Scottish top rate of 48% applies. Scottish doctors face a higher marginal rate than equivalent locums in England.

NHS pension and annual allowance

Contributions to the NHS pension scheme accrue benefit that is measured for annual allowance purposes. The tapered annual allowance applies to higher earners — the allowance reduces when threshold income exceeds £200,000. Locum work that pushes total income above the threshold income level can trigger an unexpected annual allowance charge. NHS bodies provide annual allowance statements (Pension Savings Statements) where the limit may have been breached.

Self-assessment obligations

A Scottish locum doctor must complete self-assessment if they have any untaxed income, income above £100,000 triggering personal allowance tapering, a possible annual allowance charge, or savings and investment income above the relevant threshold. Even if all income has been taxed at source through PAYE, a higher earner may still have a liability through the personal allowance restriction or annual allowance charge that requires a return.

Expenses a locum can claim

• Professional indemnity insurance premiums.

• GMC registration and medical defence union subscriptions.

• Qualifying CPD courses and medical textbooks.

• Travel between different NHS sites (not ordinary commuting).
