Registering Your Company and Workers with the SOKA-BAU Holiday Fund

We help prepare SOKA-BAU documents, organise company and employee registrations and provide ongoing administration within the agreed scope.

What SOKA-BAU is and who must register

When carrying out construction activity in Germany, foreign companies — including Polish contractors — are required to register both their business and their employees with the German holiday fund SOKA-BAU (Sozialkasse der Bauwirtschaft). This institution manages the system of holiday, training and social benefits for construction-sector workers, ensuring them equal protection regardless of the employer's country of origin.

Registration with SOKA-BAU is mandatory for companies performing construction work within the meaning of German collective labour law, even if the company is established outside Germany. This obligation arises from § 1 VTV (Verfahrenstarifvertrag — the collective agreement for the construction industry).

We help prepare registration documents and ongoing employee records, organise deadlines and coordinate questions with the relevant specialists.

Frequently asked questions

What is SOKA-BAU and what does it do?

SOKA-BAU (Sozialkasse der Bauwirtschaft) is the German holiday fund for the construction industry. It manages the system of holiday, training and social benefits for construction-sector workers, ensuring them equal protection regardless of the employer's country of origin. Its purpose is to safeguard workers' rights to paid leave and training benefits, even in cases of short-term employment or frequent changes of employer.

Does a Polish construction company have to register with SOKA-BAU?

Yes. Registration with SOKA-BAU is mandatory for companies performing construction work in Germany within the meaning of German collective labour law — even if the company is established outside Germany, for example in Poland. The obligation arises from § 1 VTV (Verfahrenstarifvertrag — the collective agreement for the construction industry) and covers both the company itself and its employees.

What happens if I fail to register with SOKA-BAU?

Failing to register may result in financial penalties as well as claims from German institutions.

How does SOKA-BAU registration and reporting work?

The process involves verifying whether your business profile qualifies the company for registration under § 1 VTV, submitting the registration documents and opening an employer account in the SOKA-BAU system, and then registering your construction workers. This is followed by ongoing administration: monthly holiday-contribution declarations, mandatory reports, correspondence and monitoring the timeliness of payments into the holiday fund. Optima Prime Consulting helps organise documents, registrations and ongoing reporting within the agreed scope.
