The new functionality is currently in test mode, but all incoming declarations are considered by the tax authority in the general order - just like those received through other channels. It is available if the user has a qualified electronic signature, which they use to log into the IE Personal Account.
You can fill out and send the declaration in your personal account in the "Life Situations-NBO" section. The interface is presented in the form of a step-by-step filling. After filling in the data on the taxpayer's activity, the service automatically calculates the values using formulas, which reduces the likelihood of errors.
The "Personal Account of an Individual Entrepreneur" mobile application provides a function for tracking the status of a submitted declaration.
