It usually goes on your main job, so your second job is taxed from the first pound, often on a BR code: 20% on all of it. If the allowance is on the wrong job, ask HMRC to move it. This is an estimate. Your payslip can be a little different because of how your employer rounds figures or when deductions are taken. We've assumed 2026/27 rates for England, Wales and Northern Ireland, a standard tax code, no pension and no student loan; change these under More options. The pension is on the main job only; each job takes student loan repayments separately. [Together you take home £2,759.97 Breakdown](#result) ## Why your payslip might differ Your payslip can be different from this if: - your tax code isn't 1257L (check the code on your payslip); - you pay into a pension or repay a student loan (add them under More options); - you started or changed job this tax year, and you're on an emergency code; - this month included a bonus or overtime; - you have more than one job; - you live in Scotland, where the tax rates are different. For hours or pay, ask your payroll team. For a tax code, ask HMRC. [Why is my pay different this month?](https://computenow.co.uk/guides/why-is-my-pay-different-this-month/) ## How two jobs are taxed Your Personal Allowance is usually used by your main job, so your second job is taxed at 20% from the first pound under tax code BR. National Insurance is worked out separately for each job, so a second job paying under £12,570 a year pays none. If your main job pays less than £12,570, you can ask HMRC to split your allowance so the second job is taxed less. If your combined pay pushes you into the higher rate, code BR collects too little and HMRC will adjust your code or ask for the difference. ## Common questions ### Why is my second job taxed so much? Your tax-free allowance (£12,570 a year) can only be used once. It usually goes on your main job, so your second job is taxed from the first pound, often on a BR code: 20% on all of it. If the allowance has been put on the smaller job, ask HMRC to move it to the job that pays more. ## Related calculators [Take-home pay calculator Your pay after Income Tax and NI](https://computenow.co.uk/take-home-pay/)[Compare two salaries See the difference after tax](https://computenow.co.uk/compare-salaries/)[Income Tax calculator Your tax band by band](https://computenow.co.uk/income-tax-calculator/) ## Guides and help ### Our guides [What does my tax code mean? 1257L, BR, 0T and K explained Read your code and see what it does to your pay](https://computenow.co.uk/guides/tax-codes-explained/)[How Income Tax bands work in 2026/27 Personal Allowance, basic, higher and additional rate](https://computenow.co.uk/guides/income-tax-bands-2026-27/)[National Insurance in 2026/27 Rates, thresholds, category letters and salary sacrifice](https://computenow.co.uk/guides/national-insurance-2026-27/) ### Official services and free advice [Tax codes explained GOV.UK: what yours means, and fixing a wrong one](https://www.gov.uk/tax-codes)[Check your Income Tax for this year GOV.UK: your tax code and pay so far](https://www.gov.uk/check-income-tax-current-year)[National Insurance GOV.UK: what you pay and what it counts towards](https://www.gov.uk/national-insurance) ## Sources Each source was last checked on 18 October 2026. - [GOV.UK: Rates and thresholds for employers 2026 to 2027](https://www.gov.uk/guidance/rates-and-thresholds-for-employers-2026-to-2027) - [GOV.UK: Income Tax rates and Personal Allowances](https://www.gov.uk/income-tax-rates) - [GOV.UK: National Insurance rates and categories](https://www.gov.uk/national-insurance-rates-letters) These results are an estimate, not financial advice.
