When your tax return has been processed by the tax authorities, you will receive a tax settlement notice. It contains information about the income on which the tax assessment is based, how much tax your employer has deducted and whether you have paid too much or too little tax. You will receive the tax settlement notice in June, August, September or October in the year following the income year.
If you have paid too little tax, you must pay the remaining amount by the due date that you find on the giro that accompanies the tax settlement notice. If you have paid too much tax, the excess amount will be refunded.
