Check the region and allowance taper
The base scenario uses the England, Wales and Northern Ireland income-tax model, with employee National Insurance shown separately. Choose Scotland in the country assumptions to switch the stored income-tax bands.
The model reduces the personal allowance above GBP 100,000. Pension salary sacrifice, student loans and payroll timing are not implemented. Monthly net is the annual result divided by 12, so it can differ from an individual payslip.
Resident employment income for a full tax year, the standard personal allowance or deductions described below, national income tax and the common mandatory employee contributions. Optional regional tax is shown where the calculator offers a state, province or region control.
Worked example: £39,000 step by step
This is the exact arithmetic the calculator runs for the default single resident employee. £39,000 is an example input chosen to illustrate the schedule, not an official wage statistic (why).
- Gross salary£39,000
- Personal allowance / standard deduction−£12,570
- Taxable income£26,430
- £26,430 taxed at 20.0%£5,286
- Income tax after model adjustments−£5,286
- Employee contributions−£2,114
- Annual take-home pay£31,600
- Monthly take-home (÷ 12)£2,633
Effective deduction rate: 19.0%. Marginal rate on the next unit of pay: 28.0%, so a £1,000 raise adds about £720 to annual take-home.
Effective vs marginal rate across salaries
The effective rate rises gradually because each band taxes only its own slice of income. The marginal rate shows what happens to the next pay rise. In United Kingdom the marginal rate peaks at 62.0% around £100,620, above the 45.0% top income-tax rate, because surtaxes, local taxes, uncapped contributions, allowance withdrawals or rebate rules stack on top of the band rate at that level. The top band starts at about £125,140 gross.
2026/27 model income-tax bands
Bands apply to taxable income after the model allowance and deductions; credits and other adjustments are applied afterwards. Some systems are approximated, as explained above.

| £200,000 | £76,203 | £6,011 | £117,786 | £9,816 | 41.1% | 47.0% |
Income tax includes any local or inhabitant tax the model applies by default. Monthly figures divide the annual result by 12 and can differ from payroll timing.
Employer cost and the total tax wedge
Employers in United Kingdom pay contributions of roughly 15.0% on top of gross salary in this model. That cost never appears on the payslip, but it matters when comparing total compensation or hiring locations.
| Gross salary | Employer contributions | Total employer cost | Employee take-home | Tax wedge |
|---|---|---|---|---|
| £29,000 | £4,350 | £33,350 | £24,400 | 26.8% |
| £39,000 | £5,850 | £44,850 | £31,600 | 29.5% |
| £78,000 | £11,700 | £89,700 | £55,797 | 37.8% |
Tax wedge = (employee deductions + employer contributions) ÷ total employer cost. At £39,000, the employer spends about £142 for every £100 the employee takes home.
