Police Overtime After Tax –
Why It Feels Smaller
You work 10 hours on a rest day. The headline number looks strong. Then payday arrives and it feels… smaller than expected.
This guide explains exactly why that happens.
Not because overtime is “over-taxed”. Not because payroll is wrong. But because of how marginal tax, National Insurance and pension deductions work in UK policing.
If you understand the structure, the frustration makes more sense.
Executive Summary
- Overtime is taxed at your marginal rate.
- Higher earners often see 40% income tax applied.
- National Insurance is calculated in bands.
- Overtime is not pensionable, so no pension is deducted from it.
Overtime is simple in theory: it is added on top of what you already earn.
The Core Concept: Marginal Tax
The UK tax system works in bands. You do not pay 40% on all your income; you only pay 40% on income above the higher-rate threshold.
However, when you earn overtime, it is added on top of your base salary. This means it often lands directly inside your highest tax band.
The Threshold Trap
Pension comes off before tax, so this Constable has £5,475 of headroom. Overtime beyond that pushes taxable pay above £50,270 and is taxed at 40% instead of 20%. Overtime is not pensionable, so it gets no pension deduction.
Tax Bands
Standard England & Wales bands. If you are close to the threshold, most OT may be taxed at 40%. New recruits are on the 7-point scale (appointed on/after 1 April 2013); the older 8-point scale applies only to officers appointed before that.
National Insurance
& Pension Dedutions
Income tax isn't the only factor. National Insurance (NI) is calculated per pay period, meaning monthly spikes can increase your NI liability.
Overtime is not pensionable, so no pension contribution is taken from it. That also means it does not reduce your taxable pay the way your normal pension contributions do, and it adds nothing to your future pension.
National Insurance Impact
Calculated per month. Spikes may temporarily move you into different NI bands.
Pension Contributions
Short-term reduction, long-term benefit. Deductions on basic pay are 12.88% to 14.22% for the 2015 scheme in England and Wales from 1 April 2026 (SI 2026/267); overtime is not pensionable.
Example Scenario
Marginal taxation in action for a Sergeant at the top of pay point 4 (£58,175). After 13.88% pension their taxable pay is about £50,100, roughly £170 under the higher-rate threshold, so this example applies to overtime earned once that £170 has been used.
Based on a 10hr Rest Day at 1.5x: hourly rate £58,175 × 6/12520 = £27.88 (Annex F), or £41.82 at 1.5x (Annex H pays 3/64 of a day's pay per 15 minutes). £58,175 is the calculated 2026/27 figure (£56,208 + 3.5%).
Headline: £418. Take Home: ~£243.
Nothing unusual happened. This is the natural result of sitting in a higher tax bracket.
Why It Feels Worse
Psychology plays a major role. Your base pay feels stable and certain. Overtime feels extra — a special effort that deserves a special reward.
When extra effort is met with heavily reduced pay, it feels like a loss. In reality, it is taxed at the exact same rates as your base. The only difference is its position in the band.
Payroll Distortion
Payroll systems calculate tax per period. Large payments in a single month may temporarily push you into a higher band, causing a larger deduction that month.
HMRC reconciles total earnings over the full tax year. Short-term spikes rarely mean permanent higher taxation across the year.
Does Overtime Ever Not Feel Worth It?
Financial gain is only one side of the coin.
High earners in top tax bands see diminishing returns. The net hourly rate drops significantly.
Cognitive fatigue increases. Decision-making is impacted. Errors are more likely.
Rest periods shorten. Work-life balance suffers. Burnout risk is amplified.
Common Misunderstandings
False. It is simply added to your total income and taxed at your current marginal rate.
Unlikely. Large OT payments can push part of that month's pay into a higher band; cumulative PAYE usually evens this out over the tax year. Your tax code itself does not change because of overtime.
Common Questions
• Why is my overtime taxed at 40%?
Because it sits above the higher rate threshold when added to your base pay. Overtime is added to your existing income, meaning it often lands directly inside your highest tax band. For example, a top-of-scale Constable on £52,015 (calculated 2026/27 figure) has £44,795 of taxable pay after a 13.88% pension contribution, so the first £5,475 of overtime in the tax year is taxed at 20% and anything beyond that at 40%. A Sergeant on £58,175 has about £50,100 of taxable pay, only about £170 below the threshold, so overtime is taxed at 40% from almost the first pound.
• Does overtime push me into higher tax permanently?
Only if your total annual income exceeds the threshold. HMRC reconciles your total earnings over the full tax year.
• Is overtime pensionable?
No. Overtime is not pensionable pay in the 2015 CARE scheme, so no pension contribution is deducted from it and it does not add to your future pension. It is still subject to Income Tax and National Insurance.
• Is it worth doing overtime in higher tax bands?
This depends on your financial priorities and fatigue tolerance. While the net gain is lower at the 40% band, it still represents a significant increase in cash flow for many.
• Can payroll over-deduct tax?
Temporary distortions can happen if a large overtime payment pushes you into a higher band for a single month, but these are reconciled by HMRC over the tax year.
