Starting in April 2026, employers in the Czech Republic will benefit from a major administrative reform: a single monthly report will replace up to 25 separate paper forms. The law, signed by President Petr Pavel in August 2025 (hrad.cz), marks a decisive step toward bureaucracy simplification and the digitalization of labor relations.
How the system works
The new system, known as JMHZ, requires employers to submit electronically to the ČSSZ (Czech Social Security Authority) all data related to employees and their income. The information will then be automatically forwarded to other public institutions, eliminating the need for multiple submissions.
The single monthly report will include three main sections:
- general company data,
- tax and contribution data,
- individual employee information.
Submission will be done exclusively online, via the ČSSZ ePortal, the official datová schránka (digital mailbox), or API integration. Employers must send the data by the 20th of the following month.
When it comes into force
The obligation will start on April 1, 2026, with the first report covering the first quarter of the year. Until then, a testing phase will allow companies to adapt to the new reporting system.
Expected benefits
According to the Ministry of Labour and Social Affairs, the reform will significantly reduce the administrative burden on businesses, particularly small and medium-sized enterprises.
Authorities expect substantial time and cost savings, fewer errors, and more efficient public administration.
With the single monthly report, the Czech Republic is aligning with other European countries that are investing in digital administration and simplified compliance for businesses.
