The filing of tax returns for 2025 began on Thursday, and will run until October 31.

In a statement, the tax department said all employees, pensioners and self-employed persons – and whose gross annual income exceeds €19,500 – must file a tax return by that deadline.

October 31 is also the cutoff date for the payment of outstanding taxes.

Tax returns filed belatedly incur a €150 penalty.

The filings must be made online using the Taxisnet system.
