Czech Republic Introduces Unified Monthly Employer Report (JMHZ): Major Simplification of Employee Notifications Starts April 2026

Czech Republic introduces Unified Monthly Employer Report (JMHZ): major simplification of employee notifications starts April 2026.

Prague, April 1, 2026 — Starting this month, employers in the Czech Republic will benefit from a significant administrative reform with the launch of the Jednotné měsíční hlášení zaměstnavatele (JMHZ) — the Unified (or Single) Monthly Employer Report. This new system consolidates nearly 25 separate notification forms into one streamlined monthly electronic submission.

The reform, introduced under Act No. 323/2025, applies to all employees regardless of nationality — Czech nationals, EU/EEA citizens, and non-EU foreigners alike. It eliminates the previous fragmented reporting requirements to multiple institutions, including the Czech Social Security Administration (ČSSZ), Labour Office, tax authorities, and statistical office.

Key Features of the New JMHZ System

• Single Consolidated Report: Employers will submit one electronic report per month covering registrations, de-registrations, and other employment-related data.

• Replaces Multiple Forms: The new process eliminates the need for separate submissions for Labour Office registrations, social security notifications, and various other individual employee filings.

• Centralized Data Sharing: Information submitted through JMHZ will be automatically distributed to all relevant government authorities, reducing duplication and errors.

• Submission Deadline: Reports must be filed electronically between the 1st and 20th day of the following month.

Implementation Timeline

• January–March 2026 (Transition Period): No regular JMHZ submissions required. Employers must prepare data for retroactive reporting.

• April 2026 Onward: Full operational launch. The first standard JMHZ report (for April) is due by May 20, 2026.

• Retroactive Reporting: Data for January–March 2026 must be submitted by June 30, 2026.

• July 2026: Stricter pre-registration rules take effect — all new employees (including Czech nationals) must generally be registered before they start work.

Benefits for Employers

This reform is expected to substantially reduce administrative burden, lower compliance costs, and improve efficiency in HR and payroll processes. Foreign worker management is also simplified, as Labour Office registration and de-registration for non-EU nationals are now integrated into the single monthly report.

However, employers must adapt their payroll and HR systems to the new requirements and ensure timely, accurate data entry, especially regarding the upcoming pre-registration obligations.

Recommendations

• Update or integrate your payroll software with the JMHZ platform as soon as possible.

• Register your organization and existing employees in the new system during the transition period.

• Review internal onboarding and offboarding procedures to align with the new deadlines.

• Consult with your tax advisor, payroll provider, or legal counsel to ensure full compliance and avoid potential penalties.
