How to respond to an information request in MyTax

What is meant by ‘request for additional information’ is that the Tax Administration is asking you to give more facts and information because they are needed for the assessment of your taxes. Letters from the Tax Administration requesting additional information may concern your personal taxes, your company’s taxes, or another organisation’s taxes for which you have responsibility.

The letter you receive contains useful instructions. When the letter arrives to you via MyTax, it will be under the Tasks tab. Use Tasks to respond to the request, as well. In addition, you can respond to information requests concerning corporate income tax returns on the MyTax home page.

Finding the request letters in MyTax

  1. Select the Communication tab.
  2. Go to Information requests and select View information requests.
  3. The requests you have not yet responded to have ‘Respond to the information request’ next to them. Select Respond to the information request.

In a situation where you are answering a letter on behalf of someone else and your authorisation mandate in Suomi.fi is other than “managing tax affairs”, the way to access information requests is different:

  1. Select the Activities tab.
  2. Go to Letters and communication, and select Information requests.

This page shows all your information requests – including those you have already answered via MyTax, API or by sending the Tax Administration a completed form on paper.

Different ways to answer a letter in MyTax

Depending on the tax issue, there are several options for sending your response to the Tax Administration:

  • Send the Tax Administration a tax return or a completed application form to provide the requested information. This is the recommended way to answer a request letter in MyTax. However, this option is only visible on the screen in some circumstances.
  • Use MyTax to send a letter in free text. There are situations where the free-text letter is the only way to give a response in MyTax.

MyTax will indicate the options that are available in your situation. MyTax will leave out the options that you cannot choose. When MyTax is giving you more than one option, we recommend that you click the “File tax return or request” button.

More detailed instructions:

  • When you click File tax return or request, MyTax will display the relevant tax return, application or request that you need to complete and submit.
  • Check the entire tax return, application, request and add the information you need to give.
  • If the request for additional information contains no reference to attaching any scans, photocopies, receipts, or free-form documents, you should refrain from adding them to your response because you are not asked to do so.
    Note: normally, MyTax does not allow you to add attachments, documents, etc. This would only happen in less frequent situations.
  • We recommend that you give your reply using the File tax return or request button although MyTax might be offering you an option to add a free-text document. After you have sent your return, application, etc., please refrain from writing an additional free-text letter. This would only make processing slower.
  • When you click Add free-form response, a MyTax field will appear where you can write free text and add any attachments that are needed.
  • Make sure to read the instructions included in the request for additional information. This way, you will know the exact content of the information you need to give. Please note that if you have already written something in the field, the text will disappear when you open the letter.
  • Either write the requested information into the field designed for it, or click “Add file” to attach separate files containing your text.
  • Maximum quantity of attachment files is 20. The following file formats are accepted: pdf, rtf, doc, jpeg, tiff and png. Maximum file size for one attached file is 60 megabytes (MB). If needed, you can combine several files into one attachment in order to include all necessary documents.
  • Note: Please refrain from sending answers in free text when you have given us a response already, by filing a tax return or an application form that contained the requested information. This would only slow down the process. For example, if you received a request for additional information asking you to submit a report to the Incomes Register, please refrain from writing us an additional free-text letter through MyTax.

What is my deadline for answering?

You can find the deadline date on the request letter itself. If necessary, you can log in to MyTax to check the date. Select Open letter (pdf) on the Information requests page. It may be that you have asked for an extension of time: if your request was granted, you can find the extended deadline date in MyTax.

You have time to answer the request letter and add further information to your answer for as long as MyTax continues to display the “respond” link.

In addition, some letters requesting additional information indicate a euro amount of a tax or an increased tax. If you send no reply after receiving such a letter, the Tax Administration will impose the tax and the tax increase according to the amounts indicated on the letter.

Note: the Tasks tab in MyTax may sometimes still display a request letter even if you answered it already by sending a tax return, a completed application or request form through another means of communication. Tasks may keep displaying a request letter also in situations where there is no absolute need to answer it.

If you cannot use MyTax

Please read the request letter for additional information to check what you need to do in case you cannot log in to MyTax to send the Tax Administration a response.
