Step 2: Income Tax

Everything above your Personal Allowance is taxed at 20% (the basic rate).

£45,000 - £12,570 = £32,430 taxable
£32,430 × 20% = £6,486 income tax

Step 3: National Insurance

You pay 8% National Insurance on earnings between £12,570 and £50,270.

£32,430 × 8% = £2,594 National Insurance

Which Tax Band Are You In?

At £45,000, you're a basic rate taxpayer. Your entire taxable income falls within the 20% tax band.

Tips to Maximise Your Take-Home Pay

Pension salary sacrifice

Contributing more to your pension via salary sacrifice reduces both your income tax and National Insurance. At £45k, every £100 sacrificed saves you £28 in tax and NI.

Watch the higher-rate threshold

You're close to £50,270. If you get a bonus or pay rise that pushes you over, consider increasing pension contributions to stay in the basic rate band.

Check your tax code

Make sure you're on 1257L. A wrong tax code could mean you're overpaying hundreds of pounds per year.
