Czech Employer Reporting in 2026: JMHZ Requirements and Deadlines
The Czech Single Monthly Employer Report, known as JMHZ, is now the central monthly filing for employers with at least one employee subject to Czech legislation. Employers report employee, social-insurance and employment-income-tax information to the Czech Social Security Administration (CSSA) between the first and twentieth day of the following month.
The system launched in April 2026 and replaced many separate submissions. Registration rules tightened on July 1, 2026: a new employee must be registered before work begins, and foreign-worker notifications now run through JMHZ rather than the previous information-card process.
Who must submit the Czech JMHZ report?
Every employer, including a foreign employer, that employs at least one person subject to Czech legislation must submit the Single Monthly Employer Report. The obligation can also reach employers that pay Czech employment income tax even when their prior registration position was different.
JMHZ covers traditional employment and other reportable dependent-work relationships. Confirm the treatment of each worker type in the payroll system instead of assuming only standard employment contracts belong in the report.
What information does JMHZ include?
The report brings together employee identification, employment details, social-insurance contributions, tax on employment income and other data used by Czech public authorities. CSSA receives the electronic filing and distributes the information to the participating institutions.
The official rollout guidance says JMHZ replaces up to 25 separate reports. That reduces duplicate submissions, but it also makes the payroll source data and employee register more important. One incorrect record can affect several reporting purposes.
What are the current JMHZ deadlines?
| Requirement | Current timing | Where it is handled |
|---|---|---|
| Monthly JMHZ filing | Submit between the first and twentieth day of the month after the reporting month. | Czech Social Security Administration (CSSA) |
| First employer registration | From July 1, 2026, register no later than two days before the first employee starts, and no earlier than 15 days before. | JMHZ employer register |
| New employee registration | From July 1, 2026, register before the employee starts work, and no earlier than eight days before the expected start. | JMHZ employee register |
| Foreign employee start | Register the worker through JMHZ before work begins. | JMHZ employee registration process |
| Foreign employee changes or exit | Report through the relevant JMHZ registration action within the applicable deadline. | JMHZ; the change-of-workplace guidance uses an eight-calendar-day deadline |
The monthly filing window and the event-based registration rules perform different jobs. A monthly report does not replace the need to register a new employee before the person starts work.
How are foreign employees reported in 2026?
Since April 1, 2026, JMHZ employee registration has replaced the former information-card and employer-notification process for the start of foreign employees. Employers must register foreign nationals who perform dependent work before the work begins, including people whose role does not create sickness-insurance participation.
Use the relevant JMHZ action to report an end of employment or a change. The Czech Labor Office guidance states that a change in work location, where the employment relationship continues, is reported within eight calendar days. Immigration and work-authorization duties remain separate and should be checked for the individual.
What should employers do now?
- Confirm that every Czech payroll and reportable worker population is mapped to JMHZ.
- Set an owner for employer registration, employee registration, monthly filing and correction workflows.
- Collect required starter data early enough to register each employee before work begins.
- Reconcile payroll, social-insurance and wage-tax data before the monthly filing window closes.
- Test how the payroll system handles changes, terminations, retroactive pay and corrected reports.
- Keep submission confirmations, error messages and corrected records with the payroll audit trail.
Employers that use a local payroll provider still need clear data and approval responsibilities. The service agreement should identify who prepares, reviews, submits and corrects each report and who monitors regulatory changes.
Prepare Czech payroll data before the reporting deadline
Safeguard Global's managed Global Pay service can support organizations that employ through their own entities with local calculations, filings, reporting and a consistent operating workflow. Employer of record support may be another option for a supported role when the organization does not have a Czech employing entity.
