How Much Can You Earn Before Paying Income Tax in the UK?
The answer depends on your situation — employment, self-employment, marriage status, and whether you are a student all affect how much you can earn tax-free.
The Standard Answer: £12,570
For most people in England, Wales, and Northern Ireland, the tax-free threshold is £12,570 per year for 2025-26. This is the Personal Allowance — the amount of income you can earn before paying any income tax.
Breaking it down by pay frequency:
- £1,047.50 per month before income tax starts
- £241.73 per week before income tax starts
- £48.35 per day (assuming 5-day working week, 52 weeks)
The Personal Allowance has been frozen at £12,570 since the 2021-22 tax year. It is set to remain at this level until at least 2027-28.
National Insurance: Aligned Since 2022
National Insurance (NI) is a separate charge on top of income tax. Employees pay NI at 8% on earnings between the Primary Threshold and the Upper Earnings Limit. Since July 2022, the Primary Threshold has been aligned with the Personal Allowance at £12,570, meaning both income tax and NI start at the same point.
So your overall tax-free threshold is £12,570 for both income tax and NI as an employee. Earn below this in a tax year and you owe nothing for either. Note that even below the Primary Threshold, NI contributions count towards your State Pension record if you earn above the Lower Earnings Limit (£6,396 for 2025-26).
How Different Situations Affect Your Threshold
Married Couples: Up to £13,830
If you are married or in a civil partnership and your spouse earns above the Personal Allowance, you may be able to claim Marriage Allowance. The lower-earning partner transfers £1,260 of their unused Personal Allowance to the higher earner, who gets a tax reduction of up to £252/year. The recipient's effective tax-free amount rises to £13,830 (£12,570 + £1,260).
The lower-earning partner must earn below £12,570, and the recipient must be a basic-rate taxpayer. Claims can be backdated up to four years.
Students with Part-Time Income
Students pay the same income tax rules as everyone else. If you earn below £12,570 in a tax year — very common for part-time workers and those who only work during holidays — you owe zero income tax.
Important: if you are employed, your employer will deduct PAYE tax in-year based on your tax code. If your total annual earnings end up below £12,570 after you stop a seasonal job, you may have overpaid tax and should claim a refund via HMRC's online services or a P50 form. Student loans have a separate repayment threshold (Plan 2: £27,295 for 2025-26) — see our student loan calculator for details.
Self-Employed: Same £12,570 for Income Tax, but NI Differs
Self-employed individuals have the same £12,570 Personal Allowance for income tax. However, National Insurance works differently:
- Class 2 NI: From 2024-25, Class 2 NI is no longer compulsory for most self-employed people with profits above the Small Profits Threshold (£12,570). Those with profits below £6,725 can pay voluntarily to protect their State Pension. Those with profits between £6,725 and £12,570 are treated as if they paid Class 2 contributions (they receive the credits without actually paying).
- Class 4 NI: Charged at 6% on profits between £12,570 and £50,270, and 2% above £50,270. So a self-employed person with £20,000 profit pays 6% NI on £7,430 (£20,000 − £12,570) = £446 in Class 4 NI, plus income tax on the same amount at 20% = £1,486. Total deductions: £1,932.
Scotland: Same Income Tax Threshold, Different Rates
The Personal Allowance is the same across the UK: £12,570. However, Scottish taxpayers face different income tax rates above this threshold. Scotland has six bands, with the Starter Rate (19%) beginning at £12,571 — slightly higher than England's 20% initially, but the Intermediate (21%) and Higher (42%) rates kick in earlier. NI is the same as in England.

| Earner above £100,000 | Below £12,570 | Allowance tapered; zero at £125,140 |

Savings interest: Basic-rate taxpayers have a Personal Savings Allowance of £1,000; higher-rate taxpayers get £500. Low earners (income below £17,570) can also benefit from the Starting Rate for Savings (0% on up to £5,000 of savings interest). See our savings interest calculator.
Dividends: All taxpayers have a £500 dividend allowance in 2025-26 — the first £500 of dividend income is tax-free. Above that, dividend tax applies at 8.75%/33.75%/39.35%.
Rent-a-Room: If you rent out a furnished room in your home, the first £7,500 of rental income per year is completely exempt from tax under the Rent a Room Scheme — no reporting required below this threshold.
Capital Gains: The Annual Exempt Amount for CGT in 2025-26 is £3,000 — your first £3,000 of capital gains each tax year is tax-free.
