How much tax do I pay on £45,000 UK?
On £45,000 in 2025/26 (England/Wales/NI) you pay £6,486 Income Tax and £2,594 National Insurance, leaving £35,920 net (about £2,993/month). You stay just inside the basic-rate band (£50,270 ceiling) and keep the full £12,570 Personal Allowance.
Full answer
For a £45,000 annual salary in 2025/26: Personal Allowance £12,570 (0%). Remaining taxable income £32,430 × 20% basic rate = £6,486 Income Tax. National Insurance is 8% on £45,000 − £12,570 = £32,430, giving £2,594. Total deductions £9,080, leaving about £35,920 net per year or roughly £2,993 per month. Scotland: the calculation runs through starter (19%), basic (20%) and intermediate (21%) bands, producing approximately £6,520 Income Tax — a small uplift versus rUK. A 5% workplace pension contribution (£2,250) reduces taxable pay if salary-sacrificed: Income Tax falls by £450 and employee NI by £180 (£630 saving), and the employer also saves 15% Class 1A NI (£337.50) that many schemes share back. Plan 2 student loan repayments would be 9% on £45,000 − £27,295 = £1,593 per year on top. Use the Take-Home Pay calculator to layer pension, student loan and tax code together.
