Electronic Submission of tax returns
Individuals and companies who have an obligation to submit a tax return must do so electronically.
All individuals with a gross income below the taxable threshold of €19.500 are not obliged to submit a tax return for 2023.
Administrative penalties
Administrative penalties amounting to €100 or €200 depending on the specific case, will be imposed for late submission of declarations or late submission of supporting documentation requested by the Commissioner of Taxation. In the case of late payment of the tax due, a penalty at the rate of 5% will be imposed on the unpaid tax. An additional penalty of 5% is imposed if the tax remains unpaid two months after the payment deadline.
