Income Tax for Teachers: How Your Salary Is Taxed
Understanding how income tax works is essential for every teacher in the UK. Your income tax is calculated on your taxable income — your gross salary minus your pension contributions and personal allowance. The UK (excluding Scotland) uses a three-band system: basic rate, higher rate, and additional rate. Teachers in Scotland pay income tax at different rates set by the Scottish Parliament. This guide explains how income tax applies specifically to teachers, including how pension contributions reduce your tax bill.
The Personal Allowance
Every UK taxpayer receives a tax-free Personal Allowance — the amount you can earn before paying any income tax. For 2026/27, the Personal Allowance is £12,570. This means the first £12,570 of your income is completely tax-free.
However, the Personal Allowance is reduced by £1 for every £2 of income above £100,000. This means the allowance is fully withdrawn at an income of £125,140. Teachers earning above £100,000 — typically headteachers and some senior leaders — face an effective marginal tax rate of 60% on income between £100,000 and £125,140, because they are losing their Personal Allowance at the same time as paying the 40% higher rate.

Which Tax Rates Apply to You?
How Pension Contributions Reduce Your Tax
One of the most important tax benefits for teachers is that pension contributions are deducted before income tax is calculated. The TPS uses a "net pay" arrangement, meaning your pensionable salary is reduced by your pension contribution before tax is applied. This effectively gives you tax relief at your marginal rate.
For example, consider a teacher on M6 in the Rest of England (£46,940):
| Item | Amount |
|---|---|
| Gross salary | £46,940 |
| Pension contribution (8.9%) | £4,178 |
| Taxable salary (£46,940 - £4,178) | £42,762 |
| Personal allowance | £12,570 |
| Income subject to basic rate (£42,762 - £12,570) | £30,192 |
| Income tax (£30,192 x 20%) | £6,038 |
Without the pension deduction, the taxable income would be £34,370 (£46,940 - £12,570), and the tax would be £6,874. The pension contribution saves £836 in tax — effectively reducing the cost of the £4,178 pension contribution to £3,342.
Tax and the Higher Rate Threshold
Most classroom teachers in England (including those on the MPR and UPR) fall entirely within the basic rate tax band. The higher rate threshold starts at £50,271, which means only teachers earning above this level — typically those on the leadership spine or those with significant TLR payments on top of UPR salaries — pay higher rate tax.
However, it is important to remember that tax is calculated on your taxable income (after pension deduction and your Personal Allowance), not your gross salary. A teacher with a gross salary of £52,000 who pays 9.9% pension (£5,148) has income after pension of £46,852, and after the £12,570 Personal Allowance a taxable income of £34,282, which falls entirely within the basic rate band. The pension contribution effectively keeps them below the higher rate threshold.
Tax Codes for Teachers
Most teachers will have a tax code of 1257L, which reflects the standard Personal Allowance of £12,570. If you have additional income, benefits in kind, or underpaid tax from a previous year, HMRC may adjust your tax code. It is worth checking your tax code regularly on your payslip and through your HMRC Personal Tax Account to ensure it is correct.
Common Tax Scenarios for Teachers
- Supply teaching through an agency — you may be taxed under PAYE by the agency, or you may need to complete a Self Assessment tax return if you work through your own limited company or as a sole trader.
- Exam marking — income from marking exams for awarding bodies is taxable and must be declared to HMRC, typically through Self Assessment.
- Tutoring — private tutoring income is taxable. If you earn more than £1,000 from tutoring in a tax year, you must register for Self Assessment.
- Two teaching jobs — if you hold two teaching positions simultaneously, one will be taxed using your personal allowance (primary employment) and the other will typically be taxed at the basic rate from the first pound (using a BR tax code).

Tax-Deductible Expenses for Teachers
Teachers can claim tax relief on certain professional expenses. HMRC allows a flat-rate expense deduction for teachers of £100 per year without the need for receipts. You may be able to claim more if your actual expenses are higher, but you will need to keep records. Common deductible expenses include professional union subscriptions, fees for professional bodies (such as the Chartered College of Teaching), and the cost of specialist clothing required for teaching (such as lab coats for science teachers). Note that you cannot claim for general clothing, commuting costs, or meals during the school day.
