Frequently Asked Questions
How is the High Income Child Benefit Charge calculated?
The charge is calculated as 1% of your Child Benefit for every £100 of income over £50,000. For example:
- £55,000 income = 50% repayment
- £60,000+ income = 100% repayment
This applies even if only one partner exceeds the threshold.
Can I use the Child Benefit repayment calculator if I have multiple children?
Yes. The calculator accounts for:
- £25.60/week for your first child
- £16.95/week for each additional child
Total benefits are adjusted automatically based on the number of children.
What is the difference between the Child Tax Credit calculator and the Child Benefit Tax Charge?
- Child Benefit Tax Charge: Repayment required if income exceeds £50k (applies to all claimants).
- Child Tax Credit: Separate support for low-income families (phased out for most claimants in 2024).
Do I need to repay Child Benefit if my income is slightly over £50,000?
Yes. Even £50,001 triggers a 1% repayment. Use the calculator to estimate:
- Exact repayment amount
- Adjusted taxable income
- Deadline for Self-Assessment filing
How does the CCTB benefit calculator work for UK residents?
The calculator follows HMRC’s “adjusted net income” rules:
- Includes salaries, bonuses, and rental income
- Excludes ISA dividends and pension contributions
- Applies to UK residents for ≥183 days/year
What happens if I miss the repayment deadline?
Late repayments incur:
- £100 penalty (immediate)
- 5% interest monthly on owed amounts
- Risk of HMRC investigation
Can foster parents use the Child Benefit repayment calculator?
Foster carers earning ≤£60,000 are exempt from the charge. The calculator automatically excludes eligible foster parents.
How do I prove my childcare costs for HICBC?
Submit these via your Self-Assessment:
- Child Benefit reference number
- Bank statements showing payments
- Ofsted registration details (if applicable)
