Question 3

How is after-tax income calculated?

Accepted Answer

Your after-tax (or net) income is your gross salary minus all deductions. The calculator first determines your taxable income, then calculates and subtracts Income Tax and National Insurance contributions. It also deducts student loan repayments and pension contributions based on your specific inputs. The final figure is your exact take-home pay.

Question 4

Does this calculator work for Scotland?

Accepted Answer

Yes. This tool fully supports the Scottish income tax system. By checking the "Scottish Resident" box, the calculator will automatically apply the specific Scottish tax bands and rates to your results.

Question 5

How does my tax code affect my take-home pay?

Accepted Answer

Your tax code determines your Personal Allowance — the amount of income you can earn tax-free each year. The most common code, 1257L, gives you an allowance of £12,570. If your code differs (e.g., due to benefits in kind, underpaid tax from previous years, or Marriage Allowance), your tax-free amount will be adjusted accordingly, directly impacting your take-home pay.

Question 6

What is the High Income Child Benefit Charge?

Accepted Answer

The HICBC is a tax charge that applies if you or your partner claim Child Benefit and either of you has an adjusted net income over £60,000 (for the 2026/27 tax year). For every £200 of income over £60,000, 1% of your Child Benefit must be repaid. If your income exceeds £80,000, the full benefit is effectively reclaimed through the charge.
