Bonus take-home calculator UK

Updated 12 November 2026 · Tax year 2026/27 · England, Wales or Northern Ireland · No pension · No student loan

Scope: one-off bonuses in the annual model. For permanent pay changes see the pay rise guide.

Use this page when you need a bonus take-home calculator for UK PAYE — what a one-off bonus leaves after income tax and employee National Insurance. Concrete example for 2026/27 in England, Wales or Northern Ireland (no pension, no student loan): a £35,000 salary plus a £5,000 bonus is treated as £40,000 for the year. Take-home rises from £28,719.60 to £32,319.60, so you keep £3,600 of the bonus (£1,000 tax + £400 NI come off). Put your own figures in the calculator; the annual stack is below. Payroll may still take a different NI slice in the month the bonus is paid.

Worked example — annual model

Both figures sit in the basic-rate band and below the NI upper earnings limit, so the marginal rate in this annual model is 28% (20% income tax + 8% employee NI). That matches the £5,000 pay-rise illustration on a different path.

Bonus lookup — £35,000 base salary

What different bonuses add to the year’s take-home on a £35,000 salary, using the annual model. Scotland uses the Scottish bands; the Plan 2 column assumes a Plan 2 loan (9% above £29,385) in England, Wales or NI.

BonusExtra take-home (rest of UK)ScotlandRest of UK with Plan 2
£1,000£720.00£710.00£630.00
£2,000£1,440.00£1,420.00£1,260.00
£5,000£3,600.00£3,550.00£3,150.00
£10,000£7,200.00£6,819.02£6,300.00

£20,000£13,737.80£12,102.82£11,937.80

Up to a £15,270 bonus everything stays below £50,270, so the rest-of-UK column keeps 72p of each pound. Beyond that the slice above £50,270 keeps 58p. In Scotland the 42% band starts at £43,663, so bigger bonuses keep less sooner. With Plan 2, a further 9p in each pound goes to the loan.

Why the bonus month looks different

Income tax under PAYE is cumulative, so over the tax year it comes out about the same as the annual model. National Insurance is not: it is worked out per pay period. With 2026/27 monthly thresholds (£1,048 primary threshold, £4,189 upper earnings limit), a £5,000 bonus on a £35,000 salary paid in one month is worked like this:

So in practice a one-off bonus usually keeps a little more than the annual table shows, because most of it is in the 2% NI band that month. The income tax for that month may look high, but that is cumulative PAYE catching up.

Bonus sacrifice

Many employers let you sacrifice some or all of a bonus into your pension. It goes in before tax and NI, so £5,000 sacrificed at basic rate puts £5,000 in the pension instead of about £3,600 in your account. From April 2029 only £2,000 a year of sacrifice will be free of NI.

Frequently asked questions

Will a bonus change my tax code?

No. A one-off bonus does not change your code. If you are underpaid or overpaid, the cumulative system corrects it by the end of the year.

Does a bonus affect my student loan?

Yes. Loan repayments are also per pay period, so 9% of the bonus month’s pay above the monthly threshold is taken.

Is a bonus taxed more than salary?

No. It is taxed at your normal rates; it can look higher on the month it is paid because PAYE works per pay period.

Why does my payslip differ from this calculator?

The calculator models a whole tax year on a standard 1257L tax code. Your payslip is worked out pay period by pay period, so a different or emergency tax code, a bonus month, overtime, benefits in kind or a different pension arrangement will move the figure. National Insurance and student loan repayments are also assessed each pay period rather than across the year. If the two disagree, trust the payslip and check your tax code in your HMRC personal tax account.

Bonuses on higher salaries

Base salaryBonusExtra take-home
£60,000£5,000£2,900.00
£90,000£5,000£2,900.00
£60,000£10,000£5,800.00
£90,000£10,000£5,800.00

On £90,000 a £10,000 bonus reaches £100,000 exactly and keeps 58p a pound. A bigger bonus would enter the personal allowance taper, where only 38p of each pound is kept. A salary-sacrifice pension can take the excess out of that band.

Put the bonus in the calculator

When the bonus crosses £50,270

If base pay plus bonus pushes annual earnings through the higher-rate and NI upper earnings hinge, the marginal mix changes: income tax on the slice above £50,270 becomes 40%, while employee NI on that slice falls to 2%. Use the calculator with the combined gross, then compare to the £50,270 landing.

Student loan on a bonus

If a loan plan is active, 9% (or 6% postgraduate) of earnings above the plan threshold also comes off. A bonus that lifts you further above the threshold increases the loan deduction in the annual model. Toggle one plan in the calculator; this page does not stack two plans.

What this page does not decide

It does not predict the month the bonus lands, whether payroll uses an emergency code that month, or how pension contributions treat a one-off payment. Check that payslip before treating the annual figure as the cash that month.
