Estonian CIT was intended to be a simple and safe solution for companies reinvesting profits. However, recent experience has shown that the greatest risks stem not from the tax structure itself, but from formal irregularities. One of the most problematic issues is the lack of signature on financial statements or their late submission.
At the end of 2025, many taxpayers are still asking the same question: does the announced amnesty actually protect companies using Estonian CIT that have made a formal error?
Signature on the financial statements and its tax implications
The condition for the successful selection of Estonian CIT is the correct preparation of financial statements in accordance with the Accounting Act, with the signatures of the persons obliged to do so, in particular the members of the management board or the manager of the entity.
For a long time, the tax authorities' position was clear: a missing signature or a signature submitted after the deadline meant that the Estonian CIT option was ineffective.
In practice, this led to very serious consequences, including questioning the right to Estonian CIT even for several years back, the need to settle the tax under the classic CIT rules and the calculation of tax arrears with interest.
This problem affected not only new taxpayers, but also companies that decided to change their form of taxation during the tax year.
Amnesty for Estonian CIT taxpayers – what was it supposed to concern?
The Ministry of Finance announced the introduction of amnesty for formal irregularities, in particular those related to the lack of signature on the financial report, late submission of signatures and other formal errors that did not affect the content of the report.
The assumption of the proposed changes was that solely formal irregularities should not lead to the loss of the right to Estonian CIT if the financial report was prepared correctly in terms of content and within the required time.
This project was widely anticipated by both taxpayers and tax advisors.
Legal status at the end of 2025
At the end of 2025, it should be clearly stated that the amnesty for Estonian CIT taxpayers has not yet been introduced into the applicable regulations.
This means that formally, there are still no regulations in force that would automatically eliminate the negative consequences of not signing a financial statement. The risk of challenging the right to Estonian CIT remains, and taxpayers cannot invoke the applicable amnesty provisions.
At the same time, the practice of tax authorities began to gradually change.
Current practice of tax authorities
In the second half of 2025, a move away from an extremely formalistic approach can be increasingly observed in proceedings conducted by tax authorities.
In many cases, authorities treat the lack of a signature as a formal irregularity, rather than an automatic reason for losing the right to Estonian CIT. In practice, this means that in individual cases, authorities may consider the factual circumstances and the purpose of the regulations.
It should be clearly emphasized, however, that this practice does not provide taxpayers with full legal protection. Until the amnesty is incorporated directly into law, each case will be assessed individually.
Practical consequences for companies using Estonian CIT
At the end of 2025, the situation of taxpayers using Estonian CIT is as follows.
The absence of a signature on a financial statement still poses a tax risk. Tax authorities may, but are not obligated to, adopt a more lenient approach. Taxpayers are not guaranteed uniform treatment, and in extreme cases, a dispute may end up in an audit or court proceedings.
We can therefore say that the situation is more favorable than in previous years, but it still does not provide complete security.
The most important conclusions for taxpayers
Taxpayers should not assume that the amnesty is already in effect, as it is still a legislative announcement at the end of 2025.
Financial reporting formalities should be planned in advance so that management signatures are submitted on time.
If an infringement has already occurred, it is worth analysing the situation with a tax advisor as soon as possible, rather than taking action on your own.
Legislative work should also be monitored on an ongoing basis, as the introduction of amnesty remains very likely, although its final scope may still change.
