The tax assessment notice is a summary of your tax for the past year, showing your income, deductions and allowances and tax paid.
The Danish Tax Agency (Skattestyrelsen) generates your personal tax assessment notice in early March. You can check and correct it by logging on to skat.dk.
The tax assessment notice tells you if you are entitled to a refund of overpaid tax or if you have paid too little tax. If too much has been paid, you are entitled to a tax refund. If you have paid too little tax, the outstanding tax will be charged on your taxes for the following year, or you will receive a form from the tax authorities in order to pay the outstanding tax.
Please note: It is your responsibility to check your tax assessment notice. You must correct it if amounts or information is missing or incorrect.
