The Financial Administration simplifies income tax registration

The system of automatic registration has been in place since 2023, when the Financial Administration began to rely on data from the Register of Legal Entities, Entrepreneurs and Public Authorities (RPO). From September 2026, this system will be further extended to new groups of entities, particularly in the non-profit, public and social sectors, including for example:

• foundations and non-profit organisations,
• trade unions and employers’ organisations,
• universities and schools in regional education,
• political parties and political movements,
• churches, religious societies and legal entities established by them,
• tourism organisations,
• public research institutions,
• temporary and supported employment agencies,
• non-investment funds and associations of legal entities.

The Financial Administration will obtain the necessary data directly from the relevant state registers. Registration for income tax, notification of changes and deregistration will thus take place automatically, without separate submissions by the affected entities. This simplifies the whole process and reduces the administrative burden on organisations.

The obligation to file a registration form will, however, continue to apply to those taxpayers for whom the necessary data cannot be obtained from the mentioned registers – these entities must still communicate with the Financial Administration in the standard way. The extension of automatic registration is another step towards digitalisation and more efficient communication between taxpayers and the Financial Administration.
