If you don't file a tax return, you will receive a fine. Are you late with the filing? Then the Tax Authorities will take the following steps:
Reminder: You will receive a letter asking you to still file your return. Notice: If you do not respond to the reminder, you will receive a notice with a new deadline. Administrative fine: If you still haven't filed after the notice, an administrative fine follows.
Income tax: €469 for late filing. For repeated offenses, this can go up to €6,709. Turnover tax (VAT): €82 for late filing. For repeated offenses, this can go up to €6,709.
Offense fine: If you intentionally or through gross negligence fail to file—or file an incorrect return—an offense fine will be issued.
Intent: 50% of the tax that you intentionally concealed. Gross negligence: 25% of the tax that you wrongfully concealed.
Writ of execution: If you continue to ignore these steps, the Tax Authorities can seize your assets or bank account.
Just fill it out honestly, and there is nothing to worry about.
