Frequently Asked Questions

Taxpayer service in MyTax

You can ask for advice in the MyTax chat or by calling our taxpayer service. MyTax also has a Help link, an easy way to access instructions and contact information.

When our service agents assist you on the phone in how to use the service, they can see your information in MyTax. Unfinished details will not be used in your tax assessment.

We will store your activities in MyTax so that we can investigate any faults or malfunction that may occur in the service. We will destroy the recordings after 30 days.

Taxpayers with a non-disclosure order – your information is in MyTax

If you have a non-disclosure order for personal safety reasons, MyTax shows the information covered by the order both to you and your authorised agent. At the Tax Administration, only named employees have access to the information.

In exceptional cases, a taxpayer service agent may see your contact details in a recording. The service agents are Tax Administration employees and bound by confidentiality.

Documents are not archived in MyTax

We keep documents in MyTax only for as long as we need them for tax assessment. If you need the documents for other purposes, save them on your computer or in some other way.

Frequently asked questions about MyTax

You do not need to enter all your details at once. You can make additions and corrections multiple times. Remember to submit the tax return every time you have added or corrected something. If you want to change or add details, open the tax return and fill in the new details. Whenever you have filed details on income or deductions, they will be displayed as pre-completed data on the next day.

When you add or correct something in MyTax, it is usually not required of you to add any enclosures or attachments. It is enough if you just save the receipts, vouchers and other documentation, and enter the amount – how many euros to deduct, for example – in the appropriate field. The Tax Administration will ask for more information if necessary. For example, you may have to give more information later about a household expense or about your expenses for the production of income.

Some of the fields contain a feature that allows you to add attachments (e.g. some commuting expenses and travel expenses in special sectors of work, or the sale of corporate shares and other securities). For these fields, you will see the words Attachments and “Add file”.
