Free tools for the UK tax side
The three questions every UK leaver asks, answered from your actual circumstances rather than a generic article. Built on HMRC's published rules, checked against the current guidance, and honest when the answer is genuinely borderline.
"Am I still UK tax resident?"
UK tax residency checker
Walks the full Statutory Residence Test: the automatic tests, then your ties, derived from plain questions. Honest about grey areas rather than pretending they don't exist.
Use the tool โ"How many days am I allowed back?"
Day allowance calculator
Reads the ties test backwards and gives you a number to plan flights around, plus the ladder showing exactly which tie to release to raise it.
Use the tool โ"When does my UK tax actually stop?"
Split-year calculator
For the year you leave: which split-year case fits your move, and your shrunken day budget for the rest of that year, month by month.
Use the tool โNot sure which you need? Start with the residency checker if you want a straight read on where you stand. Use the day allowance calculator when you're planning visits home. Reach for the split-year calculator in the year of the move itself. They hand off to each other, so starting in the wrong one costs you nothing.
