After the May 20 deadline for submitting personal income tax returns, many taxpayers only later realize that some information was omitted, entered incorrectly, or that an additional certificate or document has arrived afterwards. In such cases, there is still no need to start an entirely new process or rely on paper-based administration.

The Hungarian Tax Authority’s eSZJA platform provides a lesser-known but particularly practical option: the self-revision support function, which helps users modify an already submitted tax return.

What does self-revision mean?

Self-revision means that a previously submitted tax return can be corrected afterwards. This may become necessary, for example, if:

• a source of income or tax allowance was omitted,
• incorrect data was entered in the return,
• a relevant certificate or document was received after submission.

Importantly, this does not mean filing a completely new tax return, but rather correcting the previously submitted one.

How does the eSZJA platform support corrections?

One of the advantages of the eSZJA platform is that during the self-revision process it automatically loads the previously submitted tax return. This significantly simplifies the correction process, as users do not need to re-enter all information from the beginning.

The system:

• displays the modified data,
• helps users review the differences,
• calculates any resulting balance,
• automatically handles the self-revision-related fields.

As a result, the process is easier to manage even for those who do not deal with taxation matters on a daily basis.

How can self-revision be initiated?

The self-revision process can be started in a few simple steps on the eSZJA platform:

• Log in to the eSZJA platform
• Select the previously submitted tax return in the “Retrieve and modify return” menu
• Start the “self-revision support” function
• Correct the necessary data and submit the self-revision after validation

The system guides users through the required steps during the entire process.

Why is it worth taking action in time?

A mistake or missing information discovered afterwards does not necessarily mean a serious problem — the more important question is how quickly and properly the correction is made. Self-revision allows taxpayers to correct their tax return digitally and efficiently, without unnecessary administration.
