Figuring out how much Child Benefit you can get and if you’ll owe any tax on it can be tricky. Our UK Child Benefit Tax Calculator is here to help! It gives you accurate estimates so you know exactly how much you might receive and if you or your partner will need to pay any extra tax.
What Is Child Benefit?
Child Benefit is a financial support provided by the UK government to assist families with the costs of raising children. It’s available to individuals responsible for children under 16, or under 20 if they are in approved education or training. The current weekly rates are:
- Eldest or only child: £24.00
- Additional children: £15.90 per child
Note: Rates are subject to change; please refer to the official government website for the most up-to-date information.
Understanding the High Income Child Benefit Tax Charge
If you or your partner’s ‘adjusted net income’ exceeds £50,000, you may be liable for the High Income Child Benefit Tax Charge (HICBC). This charge requires you to repay a portion of the Child Benefit received, calculated as follows:
- Income between £50,000 and £60,000: The charge is 1% of the Child Benefit received for every £100 of income over £50,000.
- Income over £60,000: The charge equals the total amount of Child Benefit received.
Adjusted net income includes your total taxable income before any personal allowances, minus certain tax reliefs such as:
- Pension contributions: Contributions where you receive tax relief at source.
- Gift Aid donations: Donations to charities that qualify for tax relief.
For a comprehensive understanding of adjusted net income, visit the HMRC guidance.
