The Tax and Customs Board (Maksu- ja Tolliamet/ MTA) has closed its offices for a month due to the new lockdown restrictions. Taxes submitted on paper can be handed in until the end of May.
Due to the office closures, it will not be possible to file tax returns on paper or seek face-to-face advice. Online and phone communication channels are still available to use.
The MTA will now accept paper tax returns until the end of May. Offices are scheduled to reopen on April 12 when the restrictions come to an end.
MTA's customer service manager Heli Kullamaa said that while the vast majority of tax returns are submitted online, some people prefer to file paper copies.
This year, 585,000 tax returns have been filed so far, 98.5 percent of them electronically.
