I'm relocating from England to Scotland mid-year — how is my income tax split across the two systems?

Full answer

There is no day-by-day split. Your status as a "Scottish taxpayer" is determined for the entire tax year by a residence test: if your main place of residence is in Scotland for more of the year than elsewhere in the UK, you are a Scottish taxpayer for the whole of 2026/27; if not, you stay on rest-of-UK (England/Wales/NI) rates throughout. So a move dictates which single regime applies, not a part-year blend. HMRC needs your updated address to issue an S-prefix code (for example S1257L); until then your employer may use the wrong rates and a year-end reconciliation corrects it. The systems differ on Income Tax bands only — the Personal Allowance (£12,570, tapering above £100,000) and National Insurance (employee 8% then 2%) are UK-wide and unaffected. Rest-of-UK: 20% to £50,270, 40% to £125,140, 45% above. Scotland adds more bands: a 19% starter and 20% basic on lower income, an intermediate 21%, then higher 42% (£31,092–£62,430), advanced 45% (£62,430–£125,140) and a top rate of 48%. Scotland's higher rate bites from around £43,663 rather than £50,270, so mid-to-higher earners typically pay more. Worked example: on a £60,000 salary, becoming a Scottish taxpayer for 2026/27 means more income falls into the 42% advanced/higher zone above roughly £43,663, where a rest-of-UK taxpayer would still be at 40% up to £50,270 — leaving the Scottish bill several hundred pounds higher. A lower earner near the Personal Allowance can pay marginally less under Scotland's 19% starter band. Practical steps: tell HMRC your new address promptly, check for an S code on your payslip, and keep evidence of your main-home date in case residency is queried. Note Scotland also uses LBTT (not SDLT) on any property purchase.
