Full answer

Income Tax has not been devolved to the Northern Ireland Assembly, so taxpayers in Northern Ireland pay exactly the same Income Tax rates and bands as those in England and Wales -- the £12,570 Personal Allowance, 20% basic rate up to £37,700 of taxable income, 40% higher rate up to £125,140, and 45% additional rate above that. On a £40,000 salary in 2026/27: taxable income after the Personal Allowance is £27,430, all within the basic rate band, giving £5,486 Income Tax. National Insurance is also UK-wide and identical across all four nations: 8% of £27,430 = £2,194.40. Total deductions of £7,680.40 leave £32,319.60 take-home a year, around £2,693.30 a month. This is the same figure as an equivalent salary in England or Wales. Only Scotland sets its own Income Tax rates and bands under devolved powers -- Scottish taxpayers on £40,000 pay a different amount (see the Scottish take-home comparison). Council Tax is also replaced by domestic rates in Northern Ireland, which are calculated differently, but this does not affect payroll deductions from your salary.
