- People assessing the effect of relief-at-source pension contributions
What You Need to Know
How Income Tax Is Calculated for Employees
Your employer deducts Income Tax from your pay through PAYE (Pay As You Earn). The amount they deduct depends on your tax code, which HMRC assigns based on your circumstances. The most common tax code is 1257L, which gives you the standard Personal Allowance of £12,570.
For England, Wales, and Northern Ireland, the headline bands for someone with a standard Personal Allowance are:
- Basic rate: 20% on income from £12,571 to £50,270
- Higher rate: 40% on income from £50,271 to £125,140
- Additional rate: 45% on income above £125,140
National Insurance Contributions
Employees pay Class 1 National Insurance on their earnings. For 2025/26 and 2026/27 the rates are:
- 8% on weekly earnings between £242 and £967 (£12,570 to £50,270 annually)
- 2% on weekly earnings above £967 (above £50,270 annually)
Your employer also pays employer National Insurance on top of your gross pay. This does not reduce your take-home pay directly but affects the total cost to your employer.
Pension Contributions
The tax treatment of workplace pension contributions depends on how the scheme operates. Contributions may be deducted before Income Tax through a net pay arrangement, taken through salary sacrifice, or paid from net pay with tax relief added by the pension provider under relief at source. This calculator accepts a gross relief-at-source contribution to estimate its effect on your take-home pay.
How to Use the Take-Home Pay Calculator
- Select the tax year and where you live.
- Enter your annual gross salary.
- Add any gross relief-at-source pension contribution, including the basic-rate top-up.
- The calculator will display your estimated annual and monthly take-home pay with a line-by-line breakdown.
Frequently Asked Questions
What is a tax code and how does it affect my pay?
Your tax code tells your employer how much Income Tax to deduct from your pay. The most common code, 1257L, means you have a Personal Allowance of £12,570. An emergency tax code can mean you are taxed on a week-by-week or month-by-month basis, sometimes leading to overpayment that you later claim back.
Why does my payslip sometimes show a different amount to the calculator?
The calculator uses standard rates and allowances. Your actual payslip may differ if your tax code is different from the default, if you have a student loan deduction, if you receive taxable benefits in kind, or because payroll normally calculates National Insurance for each pay period rather than annualising it.
What factors can change take-home pay?
Pension arrangements, salary sacrifice, tax-code adjustments, benefits, student loans, and allowable employment expenses can affect deductions. This calculator does not determine whether any arrangement or relief is available or suitable.
What is the difference between gross and net pay?
Gross pay is your salary before any deductions. Net pay is what you actually receive after Income Tax, National Insurance, pension contributions, and any other deductions have been taken off.
Does the calculator include Scottish Income Tax?
Yes. Select Scotland in the calculator to apply the relevant Scottish non-savings Income Tax bands and rates. National Insurance rules remain UK-wide.
Limits of This Illustration
A tax code affects PAYE deductions. The calculator assumes a standard Personal Allowance and does not reproduce an individual's tax code or HMRC's PAYE calculation.
Between £100,000 and £125,140 of adjusted net income, the Personal Allowance taper affects the calculation. Pension contributions can affect adjusted net income, but this calculator does not assess pension suitability.
Actual net pay can change after a pay rise, job change, tax-code change, or the start of a new tax year because rates, thresholds, and payroll-period calculations may differ from this annualised estimate.
