How £45,000 is taxed in 2026/27
The first £12,570 of a £45,000 salary is covered by the personal allowance and is tax-free, leaving £32,430 in taxable income. Income Tax is charged progressively — 20% up to £50,270, 40% up to £125,140 and 45% above — so a £45,000 earner pays about £6,486 in Income Tax. The top of this salary sits in the 20% band.
On top of Income Tax, employee National Insurance takes 8% of earnings between £12,570 and £50,270 and 2% above, adding about £2,594. Together, Income Tax and National Insurance come to £9,080 on a £45,000 salary, leaving £35,920 take-home.
Monthly and weekly pay
Spread across the year, £35,920 take-home is about £2,993 a month or £691 a week. Before tax, £45,000 is roughly £23.08 per hour on a 37.5-hour working week.
£45,000 after tax in Scotland
If you live in Scotland, income tax is set by the Scottish Government and uses six bands for 2026/27 (19% starter, 20% basic, 21% intermediate, 42% higher, 45% advanced and 48% top) instead of the 20/40/45% used elsewhere in the UK. A £45,000 salary therefore leaves about £35,524 a year take-home in Scotland — roughly £2,960 a month — which is about £396 less than the £35,920 in England, Wales and Northern Ireland. Scottish taxpayers above the mid-range pay more because the 42% higher rate starts earlier (£43,662) and the top rate reaches 48%. National Insurance is reserved to the UK, so it is identical wherever you live.
