How does the Child Benefit work?

Sum the weekly benefit for your first child and any additional children.

Check if any parent in the household earns more than £50,000.

If income is between £50,000 and £60,000, calculate the percentage of the benefit that must be repaid.

If income exceeds £60,000, the charge usually equals the full benefit amount.

Smart Calculations

Calculated instantly with up-to-date HMRC thresholds. Our engine ensures 100% accuracy for the current tax year.

Pro Tip: Keep your receipts!

What makes you liable?

Weekly Rates: Rates are fixed per child and usually increase slightly each tax year.

High Income Charge: The HICBC is designed to taper off the benefit for higher-earning families.

Repayment: If you are hit by the charge, you must pay it back via a Self Assessment tax return.
