Confidentiality and Protection Agreement

To save you the hassle of dealing with clients and customs, we can quickly and easily verify whether your employees are legally authorized to work in Germany.

Just upload your identification documents and we'll get back to you with specific information.

The documents you need

To be carried on the construction site:

Every person on a construction site in Germany must carry a valid ID card or residence permit. In addition, EU citizens must be able to present an A1 certificate, and non-EU nationals must be able to present a work permit.

The contract for services requires you to inform your technicians accordingly.

Required for all:

As a subcontractor—whether self-employed or with employees—you must be able to provide, in addition to the A1 certificate, your business registration or an extract from the commercial register, as well as the exemption certificate pursuant to Section 48b of the German Income Tax Act (EStG). For the latter, you’ll need your VAT identification number (VAT ID).

With the right business liability insurance, you can effectively protect yourself from the financial consequences of unexpected events.

Withclearance certificates from your health insurance provider and the tax office, you can prevent your client from withholding any money.

Additional requirement for subcontractors with employees:

If your employees work in Germany, you must submit a written notification to Customs in accordance with Section 18 of the AEntG. Customs will forward this notification to the relevant social security fund (SOKA) for data verification (Section 20 of the AEntG and Section 6 of the SchwarzArbG).

If necessary, you must register your business and your employees with SOKA-Bau and have the relevant certificates on hand.

You must also be able to demonstrate compliance with the Minimum Wage Act (MiLoG).

Note: A basic distinction is made between “sole proprietors” and “businesses with employees.” Protecting employees working on a construction site requires numerous certifications, whereas a solo self-employed person, who is responsible for themselves, must provide fewer documents.

When working with additional subcontractors, there are other options available.

Anyone working on a construction site in Germany who is from a European country must carry either an ID card or a passport. This is for identification and verification purposes . The identification document allows German authorities to verify your identity and check your residency status and work permit.

Non-EU citizens (such as Ukrainians) require visas, long-term residence permits, or certificates of residence.

The free movement of workers gives citizens of all EU member states the right to freely choose where they work within the EU. That’s why you don’t need a separate work permit. Anyone working in Germany under their own business registration must provide clear proof of this to clients. The business license confirms that self-employment has been properly registered and may be legally carried out. Learn more here about how we can help you with business registration. For corporations, a current extract from the commercial register also serves as the basis for many clients to verify a company’s legitimacy and existence. It confirms that a company is properly registered and provides information about key company details. Find out here how we can help you compile all the necessary registry information.
On German construction sites, adequate coverage for property damage and personal injury is essential for your projects. It protects you—and, by extension, your client—from the financial consequences of defects, downtime, or loss, and is therefore a prerequisite for collaboration with many clients. Find out here how we can help you review or secure a suitable general liability insurance policy.

SOKA-BAU is the social insurance fund for the construction industry in Germany, which, among other things, ensures vacation entitlements and occupational pension plans for all employees. Registration with SOKA-BAU is always required when a subcontractor employs workers on a German construction site.

Important: As a solo self-employed person, you do not have to register with SOKA-BAU.

There are various social security funds for specific construction trades in Germany:

  • The SOKA-BAU for the main and ancillary building trades
  • The SOKA-DACH for the roofing trade
  • The SOKA-GERÜSTBAU for the scaffolding trade
  • The Malerkasse for the painting and varnishing trade
  • The Einzugsstelle Garten- und Landschaftsbau EWGaLA for gardening, landscaping and sports ground construction.

Social security regulations are complex, confusing, and prone to errors. They are strictly enforced in Germany, and compliance is regularly audited. Late filings or incorrect classifications can quickly lead to back payments. That’s why we support you in handling the process correctly, from the initial status check through to the end of the project. Learn more about our services here.

Without a valid tax exemption certificate (Section 48b of the German Income Tax Act (EStG)), your German client will withhold 15% of your compensation —this amount is paid directly to the tax office as construction withholding tax. With a tax exemption certificate, however, you are entitled to issue invoices without tax surcharges. In order for the client to accept the tax-exempt invoice, they also need a confirmation from the tax office under § 13b UStG stating that they are permitted to receive tax-exempt invoices from you. We handle the entire application process and also take care of renewals. Find out here how you can ensure, with our support, that your money is paid out in full and in compliance with the law. 
Clients in Germany must ensure that all skilled workers employed on their construction sites are covered by health, long-term care, pension, and unemployment insurance. This applies in particular to Eastern European subcontractors. For this reason, many clients work only with companies that properly fulfill their legal obligations and correctly pay their social security contributions in their home country. The certificate of good standing from the relevant health insurance provider serves as the key proof of compliance. This certificate is valid exclusively for the insured individual in question. Find out here how you can ensure, with our support, that all required documentation is submitted on time and in full.
Many clients in Germany work exclusively with companies that properly fulfill their tax obligations. The tax clearance certificate issued by the tax office serves as proof that your company is registered for tax purposes and meets its tax obligations. Especially when dealing with foreign subcontractors, this certificate is an important part of the project approval process in practice. If this proof is missing, it often leads to follow-up inquiries, delays, or, in some cases, payment withholdings by clients. Find out here how you can establish clarity and strengthen your clients’ trust with our support.
The A1 certificate of posting is a mandatory document! The A1 certificate is issued by the social security agencies in your home country and applies to all employees and self-employed individuals who work across the border in Germany. It proves that you are subject to the social security laws of your home country and meet all requirements. This way, you won’t have to pay social security contributions twice. It is important to carry the A1 certificate with you from your first day of work until the end of your assignment and to present it to the relevant authorities upon request. In the short term, a copy of your application for an A1 certificate is sufficient for presentation. Find out here how we can assist you with the A1 certificate.
This law establishes a statutory minimum wage that also applies to skilled workers from Eastern Europe who work in Germany (MiLoG). In addition to the general statutory minimum wage, there are sector-specific minimum wages. These can be significantly higher than the general minimum wage, particularly in the construction industry, and are mandatory.
For projects on German construction sites, many clients require written proof confirming that your employees are being paid correctly in accordance with applicable regulations. Here, you’ll learn how we can help you be fully prepared for inspections.
For assignments on German construction sites, a posting notification must generally be submitted to customs in advance in accordance with Section 18 of the German Posting of Workers Act (AEntG) . This notification reports the deployment of foreign companies and skilled workers and ensures that all legal requirements are met. If the posting notification is missing or incomplete, this can result in construction stoppages, fines, and—in practice—often a withholding of payment by the client. Here, you can learn how we can help you file a correct notification with customs.
