Certificate of Exemption

Certificate of Exemption - The certificate of exemption is a document issued by the tax office pursuant to § 48b of the German Income Tax Act (EStG) that exempts the client commissioning construction work from the obligation to withhold a tax deduction equal to fifteen percent of the consideration and remit it to the tax office.

What is the construction withholding tax, and why is there a certificate of exemption?

Since 2002, construction services in Germany have been subject to the so-called construction withholding tax pursuant to Sections 48 through 48d of the German Income Tax Act (EStG). The legislature introduced this measure to curb undeclared work and illegal employment in the construction industry. Accordingly, the client commissioning a construction service is generally required to withhold fifteen percent of the invoice amount and remit it directly to the tax office of the contractor performing the work. This tax withholding applies regardless of whether the client is a private individual, a company, or a homeowners’ association, provided that the de minimis threshold of 5,000 euros per calendar year is exceeded. For landlords, the exemption threshold is 15,000 euros.

The exemption certificate waives this withholding obligation. If the contractor presents the client with a valid exemption certificate, the client may pay the full invoice amount without having to withhold tax. The certificate verifies that the contractor is properly fulfilling their tax obligations and is registered with the relevant tax office.

For clients, verifying the exemption certificate is not merely a formality but a matter of liability. Anyone who pays for construction services without withholding tax and without having a valid exemption certificate from the contractor is personally liable to the tax office for the amount not withheld.

What constitutes construction work under the law?

The term “construction work” is broadly defined in the Income Tax Act (EStG). It includes not only traditional structural work but also:

• Masonry, carpentry, and roofing work
• Electrical and plumbing installations in new construction or renovations
• Facade and flooring work
• Scaffolding work
• Demolition and dismantling work
• Landscaping and outdoor facilities, to the extent that earthwork and groundwork are performed

However, pure maintenance services without structural intervention, cleaning work, or the mere delivery of building materials without installation are not subject to construction withholding tax. In borderline cases, a tax advisor should clarify whether a specific service is subject to withholding tax.

Verification and Validity of the Exemption Certificate

The exemption certificate is issued by the contractor’s tax office and may be granted as a single-use or permanent certificate. A single-use certificate applies to a specific contract; a permanent certificate is time-limited and covers all construction services within the validity period. Clients should always verify whether the certificate is still valid at the time of payment.

The authenticity of an exemption certificate can be verified through the Federal Central Tax Office (BZSt). A verification tool is available on the BZSt website where the certificate’s security feature can be entered. We strongly recommend performing this check for every new contractor, especially for larger contract volumes.

Issuance of the Exemption Certificate - Requirements

The tax office issues the exemption certificate if the following requirements are met:

• The contractor fulfills their tax filing and payment obligations
• There are no significant tax arrears
• There are no indications that tax obligations will not be met in the future

Taxable contractors who do not receive an exemption certificate effectively lack an important indicator of reliability in the market. For clients, the absence of a certificate is a warning sign that should be thoroughly investigated.

Practical Tip for the Nuremberg Region

In the Nuremberg metropolitan region, construction activity has been high for years, and numerous renovation projects in neighborhoods such as Gostenhof, St. Leonhard, or the Südstadt make the use of construction companies the norm. We advise builders and property owners in Nuremberg and the surrounding area to request the exemption certificate before placing an order and not only upon invoicing. This allows you to determine early on whether a contractor is tax-compliant.

Special care is required when dealing with tradespeople from other EU countries, who are increasingly active in the region, as different tax situations may arise in these cases. Foreign contractors can apply for a tax exemption certificate from the Federal Central Tax Office-if this is not available, the client is required to withhold tax. In case of doubt, we recommend consulting a tax advisor or inquiring directly with the Nuremberg-South or Nuremberg-North tax office. Especially for larger renovation projects, such as those frequently encountered in Nuremberg’s Wilhelminian-era building stock, the withholding tax on construction work can amount to significant sums-this issue should therefore not be taken lightly.

Frequently Asked Questions About the Exemption Certificate

Who is required to provide the exemption certificate?

The obligation to provide the certificate lies with the contractor performing the construction work. They must provide the client with a valid certificate without being asked, so that the client is exempt from the withholding obligation. Clients should actively request the certificate and keep it on file along with the invoice, as the tax office may request these documents during an audit.

What happens if no exemption certificate is available?

Without a valid exemption certificate, the client must withhold fifteen percent of the gross invoice amount and remit it to the contractor’s tax office by the tenth day following the end of the filing period. If the client fails to do so, they are personally liable for the withheld tax amount. The tax office can subsequently demand payment of the amount from the client via a liability notice.

Does the construction withholding tax also apply to private builders?

Yes, the construction withholding tax generally applies to private individuals as well, provided they are engaged in business activities, such as acting as landlords. However, construction projects on owner-occupied residential property used purely for private purposes are exempt, provided the client does not rent out more than two apartments. The withholding obligation applies starting with the third rented unit, and the exemption certificate becomes relevant.

How long is an exemption certificate valid?

Permanent certificates are generally issued for three years. After that, a new certificate must be applied for. For ongoing projects and framework agreements, clients should regularly check whether the existing certificate is still valid-especially before making any major partial payments.
