How this is worked out
Annual pay is the quarterly amount times four. Tax is worked out on the annual total. If you have another job or pension that already uses your Personal Allowance, this income would be taxed.
Figures use the 2026-27 rates for England: tax code 1257L with the £12,570 Personal Allowance, no other income and no student loan. Income Tax at 20% up to £50,270, 40% up to £125,140 and 45% above. The Personal Allowance falls by £1 for every £2 of income over £100,000. Employee Class 1 National Insurance is 8% on pay between £12,570 and £50,270 a year and 2% above.
