How to file an excise duty return on fuels as a CSV file in MyTax

File the excise duty return on liquid fuels in MyTax. In MyTax, you can fill in the details required for the excise duty return on liquid fuels one by one. If you are a regular taxpayer, you can upload the data on your regular activities as one CSV file. You can make the CSV file in Excel, for example. Some IT systems used by companies may also be able to generate the file automatically.

Go to MyTax

In the excise taxation of fuels, regular taxpayers include the following:

  • authorised warehouse keeper
  • registered consignee
  • tax representative
  • small producer of biofuel oil.

If you are a regular taxpayer but you also have occasional activities, you must fill in the details on your occasional activities separately in MyTax. These details cannot be uploaded as a CSV file. 

Structure of CSV file  

Please read these instructions carefully before uploading the CSV file to ensure that the contents of the file are correctly formatted and meet the technical requirements. The data included in the file must be in the correct columns and in a specific order.

If you want to upload the data as a CSV file, the file must be structured exactly as follows:

Row 1
Address line		 Role Taxable or tax-exempt product Grounds for tax exemption Volume (in l or kg with no more than 2 decimal places)
Rows 2,3,4...
Information content of the return		 Role code Product code Code of grounds for tax exemption The volume of the products must be entered with no more than two decimal places.

MyTax considers the first row of the CSV file to be the title row and ignores it.

Separate columns in the CSV file with a semicolon (;).

If you use Excel or other spreadsheet software to generate the file, select .csv as the file name extension when you save the file to ensure that the file is in the correct format.

Enter the figures without a separator, such as a space, between thousands.

Columns
