News about Vero API

The new interfaces for reporting beverage packaging and soft drink tax have been opened on May 24, 2024.
In addition, the Tax Administration is building new interfaces for declaring alcohol tax and electricity tax. The target schedule for the alcohol tax is in the fall (August 30) and for the electricity tax at the end of 2024.

The interfaces are intended for operators who declare these excise taxes, for example soft drink manufacturers and breweries or electricity companies and electricity network operators. Accounting firms that already use Vero API interfaces for e.g. VAT reporting can benefit from the new interfaces.

  • Intended for those who work with IT development at commercial software vendor companies
  • Designed to give guidance and support to IT development
  • Not at all for error processing
  • Instead, if you detect an error or become aware of a technical problem, always use the observation form to inform the Incomes Register Unit of it.
