NHS Tax Relief Calculator

A commercial rebate company files exactly the same HMRC P87 claim (or the online 'claim tax relief for job expenses' service) that you can file yourself, then takes 30-40% of whatever refund it gets you as a fee — sometimes locked in via a multi-year assignment of your future claims, not just the current one. There's no extra relief a rebate company can unlock that you can't claim directly; the form itself takes most people under 15 minutes. This calculator shows you the real number, and our free guide walks through filing it yourself so every penny of relief goes to you.

Business mileage is travel between work locations — for example driving between community visits, moving between two sites in the same trust, or attending mandatory training at a different base. It does not include your ordinary home-to-base commute, which HMRC never treats as an allowable expense, however far you travel or however early your shift starts. If you're not sure whether a specific journey counts, HMRC's own guidance on business mileage for employees is the definitive source — see our mileage relief guide for worked examples.

Professional body fees genuinely vary — NMC, GMC, HCPC and GPhC each set their own registration fees, those fees change over time, and some staff pay reduced rates or belong to a different body entirely. Hardcoding a single figure would eventually be wrong for a large share of users. Check your latest renewal receipt or online account for the exact amount you actually paid, and enter that — it's the only way this calculator's total stays accurate for your specific situation.

It takes the numbers you've already calculated above and turns them into ready-to-use text, itemised in the same categories HMRC's P87 form and online claim service expect — for example 'Uniform: £125 — Flat rate expense for uniform laundering' and 'Mileage: £420 — Mileage Allowance Relief, business miles less amount already reimbursed'. You can copy each line straight into your own submission rather than working out how to phrase or categorise your claim yourself. It doesn't file anything on your behalf — you still submit it through HMRC directly, keeping 100% of the refund.

HMRC allows backdated claims for up to 4 previous tax years. This calculator's backdated figure is simply your estimated annual relief multiplied by 4 — it assumes you had the same expenses in each of those years, which won't be true for everyone. A nurse who registered with the NMC two years ago wouldn't have paid that fee four years ago; someone who changed roles or reduced their mileage partway through would have a different real figure for each year. Treat this as an illustration of the scale of backdating available, not a guaranteed number — work out what you actually paid and drove in each specific year before submitting a real backdated claim.

HMRC sets a flat-rate expense for nurses, midwives, healthcare assistants and allied health professionals who launder their own uniform at home without free employer laundry facilities — currently £125/year (HMRC reference EIM67240). It's a fixed amount you can claim without needing receipts for washing powder or electricity, on the basis that maintaining a uniform is a genuine cost of the job. If your employer provides free on-site laundering, you can't claim this allowance for that uniform.

HMRC's Approved Mileage Allowance Payments (AMAP) rate is 55p/mile for the first 10,000 business miles in a tax year, then 25p/mile after that (effective 6 April 2026). If your employer pays you less than this per mile for business travel, you can claim tax relief on the shortfall — the difference between what AMAP allows and what you actually received. If your employer already pays at or above the AMAP rate, there's no further relief to claim on mileage (and any amount paid above AMAP is itself potentially taxable, which is outside what this calculator estimates).

Tax relief works by reducing the income you're taxed on, not by refunding the expense pound-for-pound. So the actual cash value of £688 of allowable expenses is that figure multiplied by your marginal tax rate — the rate on your next pound of income, not your average rate across all your earnings. A basic-rate (20%) taxpayer with exactly these expenses gets back £137.60, while a higher-rate (40%) taxpayer with the identical expenses gets back £275.20 — same expenses, different cash value, because relief is worth more to someone paying a higher marginal rate.

No — this tool focuses on the most common, broadly-applicable NHS employment expenses: uniform laundering, business mileage shortfall, and professional fees, plus a general 'other expenses' field for costs like exam fees tied to your current role. It doesn't attempt to model every possible deduction (for example specialist equipment specific to a narrow role, or more complex situations). If your circumstances are unusual, use this calculator for the common expenses and check HMRC's own guidance, or a specialist adviser, for anything beyond what's covered here.

No — this is a planning and estimation tool, not personalised tax advice. It uses genuine, current HMRC figures and mechanics, but your actual entitlement depends on your full circumstances and HMRC's assessment of your specific claim. For anything beyond straightforward employment expenses, or if you have a complex tax situation, speak to an accountant or check HMRC's current guidance directly before submitting a claim.
