£45,000 salary after tax in the UK

On a £45,000 salary you take home about £35,920 a year in 2026/27, or £2,993 a month and £691 a week, with no pension and no student loan. That is a 1257L tax code in England, Wales or Northern Ireland. You are £5,270 below the £50,270 threshold where the 40% rate begins, so your pay is still taxed at 20% throughout. In Scotland the position is different, covered at the end. The take-home pay calculator lets you add your own deductions.

The basic figures

Income Tax is 20% of £32,430, which is £6,486. National Insurance is 8% of the same amount, £2,594.40. Take-home pay is £35,919.60. Monthly, that is £3,750 gross, £540.50 tax and £216.20 National Insurance.

What a pension takes at £45,000

Public sector contributions come off before Income Tax and are not reduced for National Insurance. These are the 2026/27 rates for a full-time salary of £45,000.

Scheme	Rate at £45,000	Pension paid	Take-home per month
No pension	0%	£0	£2,993.30
Civil Service alpha	5.45%	£2,452.50	£2,829.80
Local Government Pension Scheme (main section)	6.5%	£2,925	£2,798.30
Teachers’ Pension Scheme	8.9%	£4,005	£2,726.30
NHS Pension Scheme	9.8%	£4,410	£2,699.30

The difference between the lowest and highest rows is £130 a month. The schemes pay different benefits and are open to different jobs, so the rate is only part of the comparison. The guides to the NHS Pension Scheme and the Teachers’ Pension Scheme explain what you get for it.

Crossing into the 40% band

If your pay rose from £45,000 to £50,270, you would keep £3,794 of the extra £5,270, about 72p in each pound. Above £50,270 the Income Tax rate doubles to 40%, while National Insurance drops from 8% to 2%. A rise to £51,000 adds £1,346 of tax and £436 of National Insurance to the £6,000 increase, so you keep £4,218, about 70p in the pound.

The lines are frozen until 5 April 2031, so pay awards close the gap without moving the threshold. Higher rate tax explains the details, and how much of a pay rise you actually keep compares other salaries.

Salary sacrifice at £45,000

Salary sacrifice cuts your contractual pay, so tax and National Insurance are both worked out on a lower figure. At £45,000 you are a basic rate taxpayer, so each £100 you sacrifice saves £20 of tax and £8 of National Insurance and costs £72 in take-home pay. Sacrificing £1,200 a year, for a cycle scheme for example, lowers take-home pay by £72 a month. Putting the same £1,200 into your main pension takes £80 a month, because there is no National Insurance saving. Salary sacrifice schemes lists which benefits qualify, and the pension tax relief guide shows how the different relief methods work.

Some things are worked out from contractual pay, so a sacrifice can affect them. The salary sacrifice guide lists them.

With a student loan

On Plan 2, repayments at £45,000 are £1,405.35 a year, or £117.11 a month, which leaves £2,876 a month before any pension. Plan 5 would take £1,800 a year (£150 a month), Plan 1 £1,629 (£135.75) and Plan 4 £1,008.45 (£84.04). Student loan repayments from salary has the thresholds.

In Scotland

Scottish rates reach 42% at £43,663 of gross pay. A Scottish taxpayer on £45,000 pays about £396 a year more Income Tax than the figures above and is already in the higher rate band. Salary after tax in Scotland compares the two systems.
