Ways to keep more of £42k after tax
- Pay into your pension through salary sacrifice. If your employer offers it, salary sacrifice cuts both Income Tax and National Insurance, so every £100 you put in costs you less than £100 of £42k after tax.
- Claim Marriage Allowance. If your spouse or civil partner earns under £12,570, they can transfer £1,260 of their Personal Allowance to you. On £42,000 that cuts your tax by up to £252 a year.
- Check your tax code. Most employees on £42,000 should be on 1257L. An emergency code or an old benefit in kind on your code can quietly reduce your take-home pay.
- Claim work expenses. Uniform, tool and professional subscription costs can qualify for tax relief, which adds a little back to £42k after tax.
Why your payslip may show a different figure
- Tax code: an emergency code such as 1257L W1 or M1, or a K code, changes how much tax is taken each month.
- Pension and salary sacrifice: workplace pensions are often worked out on qualifying earnings, not your full salary.
- Benefits and overtime: company cars, medical cover, bonuses and overtime all change your taxable pay.
- Pay frequency: weekly and four-weekly pay periods round tax and National Insurance slightly differently from a yearly figure.
