Worked example: £45,000 salary

Step 1: Income Tax

  • Personal Allowance: £12,570 tax-free
  • Basic rate (20%): £32,430 of income from £12,570 to £45,000, taxed at 20% = £6,486
  • Income Tax due: £6,486 = £6,486

Step 2: National Insurance

  • Primary Threshold: £12,570 NI-free
  • Primary Threshold to Upper Earnings Limit (8%): £32,430 of earnings from £12,570 to £45,000, taxed at 8% = £2,594.40
  • NI due: £2,594.40 = £2,594.40

Step 3: pull it together

Amount
Gross salary£45,000.00
− Income Tax£6,486.00
− National Insurance£2,594.40
= Take-home pay£35,919.60 (£2,993.30/month)

With the Personal Allowance removed, taxable income of £32,430 sits 86.0% of the way through the basic-rate band, only £5,270 short of the £50,270 higher-rate threshold. Income Tax comes to £6,486.00 and National Insurance to £2,594.40. In total, £9,080.40 is deducted before pension contributions or student loan repayments, an effective combined rate of 20.2% of gross salary. See Income Tax Explained and National Insurance Explained for how these bands apply more generally.

What happens if income rises above £50,270

Because only £5,270 separates this salary from the higher-rate threshold, a pay rise, bonus, or overtime that pushes total income past £50,270 raises the rate only on the portion above that threshold, not on the whole salary. That portion is taxed at 40% Income Tax instead of 20%, and at 2% National Insurance instead of 8% above the equivalent Upper Earnings Limit. See Income Tax Explained for how this partial-band effect works.

Where this figure appears on a payslip

The £2,993.30 monthly average above is an annual figure divided evenly across 12 months, not a prediction for any individual payslip. National Insurance is recalculated each pay period rather than smoothed across the year, and a bonus, overtime, or a mid-year change in hours will shift an individual month's figure away from this average. See Your Payslip Explained for where each deduction shown here appears on the document itself.

Using a pension contribution to stay under the threshold

A pension contribution at this salary does more than reduce the tax bill in general: because only £5,270 of headroom remains before the higher rate, a contribution large enough to offset a bonus or pay rise can keep the whole salary within the basic rate, rather than letting part of it spill into the 40% band. See Reducing Your Tax Through Pensions for how that works, or enter a specific salary and pension percentage in the Salary Calculator for an exact figure.
