Overtime and Bonus Tax 2026: Why You're Not 'Taxed More'

Quick answer

"They tax overtime more" is one of the most persistent payroll myths in Britain — and it is wrong. Overtime and bonuses are taxed at exactly the same rates as your ordinary pay. What changes is which band the extra money lands in: if it tips you over the £50,270 higher-rate threshold, the slice above is taxed at 40%, and National Insurance applies on the whole extra amount in that period. The result can look brutal on a single payslip, but it is your marginal rate at work, not a penalty. See exactly what you keep with the

, then read on for why a bonus month looks the way it does.

The myth: "overtime is taxed more"

There is no separate tax rate for overtime, bonuses, commission or shift premiums. Every extra pound is taxed using the same income tax bands as your salary:

• 20% on income up to £50,270.
• 40% between £50,270 and £125,140.
• 45% above £125,140.

If all your income — salary plus overtime — stays under £50,270, your overtime is taxed at exactly 20%, the same as the rest of your pay. The myth arises because people compare the tax on a normal month with the tax on a big month and assume the higher amount means a higher rate. It usually just means more income at the same rate, or a slice tipping into the next band.

Why a bonus month feels so painful

A bonus is bolted onto your pay for a single period, and three things combine to make that month sting:

1. The higher-rate band. If your bonus pushes your pay for the month above the monthly equivalent of £50,270, part of it is taxed at 40% rather than 20%.
2. National Insurance per period. NI is calculated per pay period, not annually. A big month means a chunk of the bonus sits above the upper earnings limit and the NI is worked out on that single inflated month — and, unlike income tax, NI is generally not smoothed or refunded.
3. PAYE smoothing optics. PAYE may temporarily over-deduct income tax in the bonus month on the assumption your pay will continue at that level, then claw it back in following months — but you feel the hit immediately.

A worked example

Daniel earns £45,000 and receives a £10,000 bonus in March.

• His salary alone keeps him under the £50,270 higher-rate threshold, taxed at 20%.
• The bonus takes his total to £55,000, so £4,730 of the bonus falls into the 40% band and the rest stays at 20%.
• That month's payslip shows a large tax deduction and noticeable NI.
• Across the full year, his income tax settles to the correct amount for £55,000 of income — but the NI hit on the bonus month stays.

His effective tax on the bonus is a blend of 20% and 40% plus NI — higher than his normal pay, but only because part of it genuinely sits in the higher band. Run the before-and-after through the

to see the split.

The 60% trap between £100,000 and £125,140

There is one place where a bonus really can be punishing: incomes between £100,000 and £125,140. In this band your personal allowance is withdrawn by £1 for every £2 of income, creating an effective marginal rate of around 60% (40% tax plus the lost allowance). A bonus that pushes you into or through this band loses far more than you would expect.

If you are near £100,000, a bonus is the classic case for diverting income before it is taxed — which brings us to the most useful tool of all.

How to keep more of your overtime and bonus

You cannot change the tax bands, but you can change how much of your extra pay is exposed to them.

Bonus sacrifice into a pension

The most powerful move is bonus sacrifice: you agree, before the bonus is paid, to give it up in exchange for an employer pension contribution. Because the money never counts as your pay:

• It escapes income tax entirely.
• It escapes National Insurance — both yours and often a share of the employer's.
• The full amount goes into your pension rather than a heavily taxed fraction reaching your bank account.

For a higher-rate taxpayer, or anyone in the 60% band, this is enormously efficient. Model it with the

and see the long-term growth with the . The trade-off is simply that you do not get the cash now — it is locked in your pension until pension age.

Other practical steps

• Time the bonus where your employer allows, to avoid stacking two large payments in one period and over-triggering NI.
• Check your tax code afterwards, because a one-off spike can occasionally distort it.
• Use Gift Aid or pension contributions to extend your basic-rate band if a bonus pushes you just over a threshold.

What about overtime specifically?

For overtime, the same logic applies but the stakes are usually lower because the amounts are smaller. If your overtime keeps you under £50,270, it is taxed at 20% and 8% NI — the same as your salary. The only time it bites harder is when consistent overtime lifts your annual income across the higher-rate threshold, at which point the extra hours above that line carry 40% tax. If that describes you, pension contributions are again the lever that keeps more of those hours working for you.

Common misconceptions, cleared up

• "It's not worth doing overtime because of tax." Unless you are in the 60% band, you always keep the majority of extra pay — typically 72% at basic rate. Working extra is virtually always worth more in your pocket.
• "I'll get all my bonus tax back." You may get over-deducted income tax back through PAYE, but not the National Insurance.
• "A bonus changed my tax code." It can temporarily; check it returns to normal.

Student loan and other deductions on extra pay

Two further deductions ride along with a bonus or heavy overtime month and add to the "where did it all go?" feeling:

• Student loan repayments are taken at 9% of income above your plan threshold, and because they are assessed per pay period, a bonus month can trigger a larger-than-usual repayment that is not refunded later even if your annual income would not have crossed the threshold smoothly. This is the same per-period quirk as National Insurance.
• Pension contributions under a percentage-based scheme rise with the bonus too, which is no bad thing — it quietly boosts your retirement saving — but it is another reason the net amount looks smaller than expected.

Once you stack income tax (possibly partly at 40%), 8% (or 2%) NI, 9% student loan and a pension slice, it is easy to see why a £10,000 bonus can land as little more than half that in the bank. None of it is a penalty; it is simply several ordinary deductions all applying at once to a large one-off sum.

How dividends differ (for company directors)

If you run your own company and pay yourself partly in dividends, the picture changes. Dividends are not subject to National Insurance, and they are taxed at the dividend rates of 10.75%, 35.75% and 39.35% in 2026/27 after the £500 dividend allowance. This is why the salary-versus-dividend mix is a perennial planning question for directors, and why a "bonus" for a director is a different decision from a bonus for an employee. The trade-offs are involved enough to deserve their own analysis, but the headline is that the per-period NI sting that hits an employee bonus does not apply to a dividend.

A quick reality check on whether overtime is "worth it"

It is worth stating plainly because the myth does real harm: declining overtime "because of tax" almost always leaves you poorer. At basic rate you keep roughly 72p of every extra £1 (after 20% tax and 8% NI). At higher rate you keep about 58p. Only in the narrow £100,000–£125,140 band, or where extra hours genuinely cost you in other ways, does the calculation get close. For the overwhelming majority of workers, extra paid hours mean meaningfully more money — the tax just takes its normal share, no more.

Other thresholds a bonus can trip

Beyond the headline tax bands, a bonus can quietly push you across other income thresholds with knock-on effects far larger than the tax itself:

• The £50,000–£60,000 child benefit charge. The High Income Child Benefit Charge claws back Child Benefit between £60,000 and £80,000 of income. A bonus that lifts you into this band can trigger a charge that effectively taxes part of the bonus at a very high combined rate, especially for larger families.
• The £100,000 personal allowance taper. As covered above, this creates the 60% effective band up to £125,140.
• Childcare support cliffs. Tax-Free Childcare and funded hours are lost once adjusted net income exceeds £100,000 — and unlike a taper, this is a hard cliff-edge where a single pound over can cost thousands in lost childcare support.

In every one of these cases, a pension contribution that reduces your adjusted net income back below the threshold can be dramatically worthwhile — sometimes the contribution effectively "pays for itself" through the support or allowance it preserves. This is why anyone receiving a bonus near £60,000 or £100,000 should pause and model the full picture before letting it hit their bank account.

Practical steps before your next bonus

• Find out the gross amount and the expected pay date so you can plan.
• Check whether bonus sacrifice into your pension is offered — and set it up before the bonus is processed, as you cannot sacrifice money you have already received.
• Identify any threshold you are near (£50,270, £60,000, £100,000) and consider whether a pension contribution keeps you the right side of it.
• Expect the per-period NI and student loan hit and do not budget for the gross figure.
• Review your tax code in the months after, to confirm any temporary distortion has corrected.

The bottom line

Overtime and bonuses in 2026/27 are taxed at your normal marginal rates — there is no penalty tax. A bonus month looks harsh because part of the money can fall into the 40% band and National Insurance bites per period and is not refunded, while over-deducted income tax usually evens out over the year. If you want to keep more, bonus sacrifice into a pension is the standout move, especially in the 60% band between £100,000 and £125,140. Check the real numbers with the
