Question 16

What is a tax code and why does it matter?

Accepted Answer

A tax code tells your employer how much tax-free income you are entitled to. The most common code is 1257L, which represents a Personal Allowance of £12,570. HMRC may adjust your code if you have untaxed income, benefits in kind, or owe tax from a previous year. An incorrect tax code can lead to over- or under-payment of tax. (Source: gov.uk/tax-codes, 2025/26)

Question 17

Does the calculator account for tax on overtime or bonuses?

Accepted Answer

Yes. Overtime pay and bonuses are taxed as regular income in the UK — they are added to your salary and taxed at your marginal rate. The calculator lets you enter your total gross pay including any additional earnings to give you an accurate take-home figure. (Source: gov.uk/income-tax-rates, 2025/26)
