Answer
If you are a salaried employee, you must inform your employer’s family allowances compensation fund of any changes in your circumstances that may have an effect on your right to child allowances. If you fail to declare this information, you will have to pay back any overpayments you have received.
If you have changed job, you must inform your former employer’s family allowances compensation fund. You can obtain the contact details of the office from either your former employer or the Family Allowances Register.
