What happens if my income or family circumstances change after I've applied for family tax credits?

If your income or family circumstances change after you have applied for family tax credits, it is important to notify the relevant tax authority immediately. Failing to inform them about changes may lead to incorrect payments and possible penalties. If your income decreases or you face unemployment, you may be eligible for additional support or an increased tax credit amount. Conversely, if your income increases significantly or you experience changes in your household, such as a new child or a change in marital status, you may receive a reduced or no tax credit. Informing the tax authority promptly helps ensure that you receive accurate entitlements and avoid any potential overpayment, which you may be required to repay later.
