From July 2025, a test run of the so-called single monthly reporting started. This new system is intended to significantly simplify the employers’ agenda – instead of dozens of different forms, they will now send one summary electronic report to the authorities. Full reporting will start in January 2026 and will affect all employers.

What is changing and why

The unified monthly reporting is based on the amendment to the Sickness Insurance Act and connects agendas that employers used to report separately – for example, income statements, reports to the Social Security Administration, employee registration and deregistration forms or some tax data. The aim is to reduce the administrative burden and improve the government’s overview of employees and contributions.

As of January 2026, employers will no longer submit the individual forms separately. They will now submit a single electronic form monthly, always from the 1st to the 20th of the following month. Obligations towards health insurance companies remain unchanged for the time being.

What all will be included in the report

The report will include a range of data that companies have previously reported separately:

employee income subject to levies,
data for sickness benefits,
a summary of employment starts, changes and terminations,
information on insurance premiums and advance tax payments,
employer and employee identification data.

What to prepare for

The introduction of reporting brings not only savings but also new risks – especially for incorrect or late submissions. Employers are responsible for the accuracy of data to several authorities at the same time. Therefore, it is important to adjust internal processes and systems in a timely manner.

We recommend:

verify that payroll software can handle the required format,
check that the data in the different systems match,
train the staff who will process the reports,
set up control mechanisms before sending,
follow the instructions of the CSSA and the tax administration on the details of the procedure.

Smaller employers will be able to use the forthcoming CSSA web application, but the final version is not yet available.

The unified monthly reporting is a step towards modernising the administration, but also a test of companies’ readiness. Those who join in time and adapt their systems can benefit from the news. Others risk unnecessary errors and fines. Early preparation is therefore definitely worthwhile.
