Increase in tax due
If you report your income late, your tax will be increased by one of the following penalties:
- 10% in the absence of formal notice
- 20% where the declaration is lodged late within 30 days of the formal notice being given
- 40% where the declaration has not been lodged within 30 days of receipt of a formal notice
Warning
Penalties for late filing are calculated on the total amount of tax due, without taking into account the prepayments and levies already paid.
Interest on late payments
Interest on late payment is also charged.
They amount to 0.20% the tax due per month of delay (i.e 2.4% over 1 year).
This interest applies until the last day of the month in which the tax return is filed.
Please note
The basis for calculating interest on arrears is reduced by the payments you have already made (e.g. withholding tax).
