Child benefit is still paid but is clawed back through a tax adjustment called the High Income Child Benefit Charge. HICBC.
Before 6 April 2024, child benefit was effectively withdrawn at a rate of 1% for each £100 earned by the higher-income partner over £50,000 a year. Therefore, the benefit is fully withdrawn where income of the higher-income partner reaches £60,000 a year.
From 6 April 2024 that was changed. The charged is now 1% of your Child Benefit for every £200 of income that exceeds £60,000. Therefore, the benefit is fully withdrawn where income of the higher-income partner reaches £80,000 a year.
That change happened as a result of campaigning by Martin Lewis. There will be a review of the situation which currently disadvantages single parents who are high earners e.g if two parents work and each earn up to £60,000 they are not subject to HICBC.
However …
Where the charge applies to a partner, it has consequences for the whole household. The charge reduces the income available to the household, but it can have more subtle and indirect consequences. The most common of these is where, as a household, you decide not to claim child benefit where the charge would apply because there would appear to be no point in doing so. This is especially likely to be the case where your partner has net adjusted income of more than £60,000 (meaning the whole amount of child benefit is clawed back) and would be required to file a self assessment tax return as a direct result of the charge. Many people decide it is not worth this additional administration burden for no financial return.
Not claiming child benefit in this scenario means that you will miss out on National Insurance (NI) credits which are given to child benefit claimants until the child is 12 years old. These can be critical to build entitlement towards a state pension and other benefits, if you do not work or you are not entitled to NI credits on some other basis. It is only possible to backdate child benefit for three months – thus, if you do not claim child benefit and miss out on NI credits as a result, there is no way to claim NI credits retrospectively beyond the three-month period.
