The preliminary filling of the VAT declaration is carried out automatically based on up-to-date information from the information systems of government agencies, including the electronic invoice information system, taxpayers' personal accounts and declarations for goods.
The principle of operation of "T-1" (Data update)
Please note that the service is running with a one-day delay. If an electronic invoice is issued or a notice of VAT offset is sent today, this information will be displayed in the system only tomorrow.
The importance of the "Confirmed" status
When calculating, the service uses only those VAT offset notices that have received the "Confirmed" status. In this regard, we strongly recommend that you fill out all notifications carefully and correctly.
Advantages and area of responsibility
Using the service helps taxpayers to check themselves when filling out the TNF and significantly reduces the risk of receiving notifications based on the results of desk control.
However, it is important to remember that the system relies on data provided by taxpayers themselves. If this information is changed or clarified by the taxpayer in the future, this may directly affect the results of desk control and lead to new notifications.
