When is the Estonian tax return deadline?
30 April — and you can start filing on 16 February. Income for 2025 is declared between 16 February and 30 April 2026, and 30 April is the last day. Most returns are pre-filled: the Tax and Customs Board already knows your salary, pension and bank interest — your job is to check and complete it. And it is the completing that brings money back: undeclared training costs, home-loan interest and donations mean a refund you never received. The refund arrives faster if you file electronically and early. And if you owe tax, the payment deadline is separate — check the date on the return itself.
📋 The rules
- Filing: 16 February – 30 April
- Last day: 30 April
- The return is pre-filled
- You must check the deductions
- Payment has a separate deadline
🔓 Exceptions
- Those in business may face separate forms and deadlines
- Training costs, home-loan interest and donations must be checked by you
- A return filed electronically and early is refunded sooner
⚠️ Penalties & fines
The costliest mistake is not lateness but undeclared deductions. The Tax Board pre-fills the return on the income side, but the deductions — training costs, home-loan interest, donations, supplementary pension contributions — are yours to check. Every forgotten line is money you never get, and nobody will remind you afterwards. The second risk is the deadline: a late return brings interest, and repeated disregard can bring enforcement penalties. And a third nuance: filing the return and paying the tax are two different deadlines — look at which date appears on your return, because any amount owed falls due later.

❓ Frequently asked
When can the return be filed?
Declaring 2025 income begins on 16 February 2026 and the last day for filing is 30 April. An electronic return filed early is refunded noticeably sooner than a late paper one.
Is the return pre-filled?
Largely yes. The Tax Board knows your salary, pension and bank interest, but the deductions must be checked and completed by you, because they are not filled in automatically.
Which deductions should I check?
Training costs, home-loan interest, donations and supplementary pension contributions. Every forgotten line means a refund you never receive, and nobody reminds you about it later.
What happens if I file late?
A late return brings interest, and repeated disregard can bring enforcement penalties. The deadline is 30 April, and it is not extended merely because the return slipped your mind.
Is the payment deadline the same?
It is not. Filing the return and paying any tax due are two separate deadlines. If you owe money, check the payment date on the return, which falls later than the filing deadline.
