UK Tax Calculator
Estimate your annual and monthly take-home pay in the UK (Income Tax, National Insurance, and optional student loan). This tool is designed for quick planning.
Assumptions: typical UK PAYE bands and thresholds for estimation only. Actual payroll outcomes may vary by tax code, benefits, bonuses, and employer setup.
How tax in the UK is usually calculated
If you are employed in the UK, most people pay tax through PAYE (Pay As You Earn). Your employer deducts money before salary reaches your bank account. The three biggest deductions are:
- Income Tax based on tax bands
- National Insurance (NI) based on earnings thresholds
- Student Loan repayments if you have an eligible loan plan
Your take-home pay is what remains after these deductions. This is why a simple salary figure can feel very different once it becomes monthly net income.
Income Tax bands used by this calculator
England, Wales, and Northern Ireland
The calculator applies a Personal Allowance and then standard progressive tax rates:
- 20% basic rate
- 40% higher rate
- 45% additional rate
It also applies Personal Allowance tapering for high incomes, which can create a much higher effective marginal tax rate between certain thresholds.
Scotland
Scottish Income Tax uses different bands and rates for non-savings, non-dividend income. That means two people on the same salary may see different tax deductions depending on where they are taxed in the UK.
National Insurance and student loan notes
National Insurance is separate from Income Tax and has its own thresholds and rates. Student loan repayment is also separate and depends on your loan plan. If your salary is below your plan threshold, repayment is usually zero.

Important limitations
This is an educational estimator, not a substitute for payroll software or professional tax advice. Real payslips can differ due to tax code changes, company benefits, bonuses, salary exchange rules, and mid-year adjustments.
