  • VAT
    IS OUR
    PASSION
    But our vision
    goes further.

What began in 2006 with our passion for VAT has now become much more. Our specialization has distinguished us from the outset – it is the basis for advice that is not only well-founded but also practical and successful. KMLZ has become synonymous with VAT experts. 

 

The world of indirect taxes, however, does not end with VAT. Over the years, we have continuously expanded our expertise to include customs law, excise taxes, and other indirect taxes. Because we know that tax challenges rarely occur in isolation.

 

Our expertise
What defines us

We don’t deal in maybes.

We provide you with clear statements. We commit ourselves because we are convinced. We will demonstrate our conviction – at home and abroad, before the tax authorities, and if necessary, also before the courts.

We go beyond borders.

Our expertise does not end with national legal issues. We are also at home with international VAT law and have a strong network that allows us and our solutions to grow continuously.

Our specialization makes us efficient.

As a result of our deep expertise, we work effectively, we are solution-oriented, and always dependable. Our team consists of recognized experts who will present you with clear and precise solutions.

Consider us as your outsourced VAT department.

We understand the challenges faced by tax departments and offer you practical, pragmatic support that is directly tailored to your needs.

Who we advise

We support small and large companies.

Whether you are a sole proprietor or a stock-listed company, we are at your side with our comprehensive VAT expertise, whether for a one-time consultation or a long-term partnership.

We advise advisors.

This is one of our areas of expertise - specifically for tax consultants, lawyers, and auditors.

Consult us to assess complex VAT issues – with full client protection.

Templates for VAT returns 2026: Impact on corrections and voluntary disclosures

With its letter dated 29 December 2025, the German Federal Ministry of Finance published the official templates of the VAT returns and the advance payment procedure for 2026. The new code number 500 requires supplementary information to be provided in the VAT return by allocating the declaration to one of four categories. The new code number 500 entails both opportunities and risks and has implications for the submission of corrections and voluntary disclosures.

Customs Newsletter 02/2026

Entry into force of the EU-Mercosur agreement remains uncertain – will it be provisionally applied?

On 17 January 2026, following 26 years of negotiations, the EU and the Mercosur countries Argentina, Brazil, Paraguay and Uruguay signed a Partnership and Trade Agreement. Its entry into force, however, remains uncertain. The ECJ is currently reviewing its compatibility with Union law. It therefore remains unclear when, and indeed whether, the world’s largest free trade area will be established.

Code of Conduct

Our donation projects

Whether it be decorating fir trees or hiding brooms, as the Norwegians do: At Christmas, we all enjoy reviving our most beautiful traditions. Many time-honoured traditions, as well as many new ones – like our fundraising campaign. Although it is only the second time we have organized it, we already know that we want to maintain this tradition to support those in need, into the future. It does not matter whether they are young or old and what kind of challenges they are facing in life.

There is one tradition, which we cannot forego:
to be there for one another.
