UK tax tools for leaving the UK — free, sourced, built on HMRC's own rules
Stop reading. Start working it out. Fifteen free tools that turn the Statutory Residence Test, the leaving-the-UK paperwork, the money you keep earning from Britain and every HMRC deadline into a personal answer — no gate, no paywall, no upsell.
Quit UK Tax's fifteen free tools turn HMRC's rules into your answer, grouped into five families: check your status (the SRT, day-counting, split-year, full-time work abroad), plan your exit, sort the money and tax you still owe Britain, work out your forms and deadlines, and compare destinations. Each runs in your browser, cites its HMRC source, and gives general guidance — not advice.

They give you guidance and estimates, not advice — and they don't submit anything to HMRC. They translate the rules into a likely position for your facts; they don't assess your personal situation, sign off your residence status, file a form, or guarantee a refund or outcome.
Common questions
Are the Quit UK Tax tools free, and do they store my data?
Yes, free — no gate, no paywall, no upsell on the core. The calculators run entirely in your browser as React islands; no personal data is stored. The only network call is the optional "email me my result" form. (Last reviewed: May 2026.)
Which UK tax residence tool should I use?
Start with the Residence Status Calculator to work out whether you're UK non-resident. Then move along the five families: plan your exit, sort the money and tax you still owe Britain, get your forms and deadlines right, and compare destinations. Run them roughly in that order. (HMRC RDR3; 2026/27.)
Do these tools submit anything to HMRC?
No. None of the tools files a form or sends anything to HMRC. They apply HMRC's published rules to your figures and show a sourced result, then point you to the official gov.uk route to file a P85, an SA109 or a capital gains report yourself. (gov.uk "Tax if you leave the UK"; 2026/27.)
Will the refund checker tell me how much I'll get back?
It gives an illustrative estimate, never a guaranteed figure. Leaving employment mid-year often means PAYE over-deducted tax, because your full £12,570 personal allowance (2026/27) was spread across a year you didn't finish. Your actual refund depends on your pay and leaving date. (HMRC PAYE94025; 2026/27.)
