Find out if HMRC owes you money — in under 60 seconds.

A professional-grade PAYE tax audit for UK employees. We check what you overpaid and hand you the exact steps to claim it back — you keep every penny.

A PAYE tax refund is money HMRC returns when you have paid more Income Tax than you owed — usually because of a wrong or emergency tax code, changing jobs, or unclaimed reliefs. UK employees can reclaim overpaid PAYE tax for the last four tax years. This audit checks the common causes against HMRC rules and tells you what you may be owed and how to claim it.

over £300 million GOV.UK

HMRC is sitting on hundreds of millions in unclaimed refunds because the system rarely tells you when you have overpaid — you have to check and ask. Most people never do.

Why now

You can only reclaim four tax years back — the oldest year expires every April. If you have never checked, a year of your refund could disappear at the next deadline.

Questions

How do I know if HMRC owes me money?+
Common signs include: tax code starting with BR, D0, 0T, or with a W1/M1 suffix (emergency tax); changed jobs in the tax year; worked from home since 2020 without claiming relief; married with a non-earning spouse; paid professional fees not reclaimed. Our audit checks all these and more.
How much could I get back?+
Typical refunds range from £60 (Marriage Allowance) to £2,000+ (emergency tax with high earnings). Work-from-home relief alone is £6 per week worked, which can add up to £312/year. We give you an estimate based on your specific situation.
What do I do after the audit?+
We provide step-by-step HMRC claim instructions — which online form to use (P87, P55, online Marriage Allowance, or Self Assessment), what to enter in each field, and how long it takes. Most claims are processed by HMRC within 6–12 weeks.
Why is this only £9.99?+
Because we audit — we do not file. You do the 10-minute submission to HMRC yourself using our instructions. Tax reclaim firms charge 20-40% of your refund; at £9.99 you keep 100% of what HMRC returns.
