MDDP nominated for Poland Tax Disputes Advisory Firm of the Year at the ITR EMEA Tax Awards 2026

MDDP’s Tax Litigation & Disputes team has been shortlisted for Poland Tax Disputes Advisory Firm of the Year at the ITR EMEA Tax Awards 2026.

The nomination reflects MDDP’s effectiveness in handling complex and precedent-setting tax disputes. It recognises both the team’s successes before Polish administrative courts and the EU courts, as well as its efforts to strengthen taxpayers’ rights, improve procedural standards and contribute to the development of tax law in Poland and across Europe.

More than 80 tax disputes

In 2025 alone, the MDDP team handled more than 80 tax disputes with a total value exceeding PLN 100 million.

These included complex proceedings before tax authorities and administrative courts, as well as precedent-setting cases before the Court of Justice of the European Union and the General Court of the European Union.

The team combines a strategic approach to litigation with extensive tax expertise and experience in handling complex proceedings. As a result, it not only effectively protects its clients’ interests but also helps shape new standards for the application of tax law.

Landmark cases before the European courts

One of the team’s most significant achievements was case C-213/24, Grzera, in which the CJEU endorsed MDDP’s arguments concerning the VAT treatment of spouses subject to the statutory matrimonial property regime. The judgment changed the established practice in Poland and may also affect the interpretation of VAT rules in other Member States.

MDDP’s experts also represented a taxpayer in case T-689/24 before the General Court. The case concerned the point at which the right to deduct VAT arises, and the judgment may significantly change the understanding of that right across the European Union.

MDDP also successfully represented a taxpayer in case C-453/23 concerning State aid and real estate tax. The significance of the judgment extends beyond the Polish tax system and may influence how tax advantages are classified in other EU Member States.

Strengthening taxpayers’ rights in Poland

At the national level, the MDDP team secured a series of important judgments strengthening the protection of taxpayers’ rights and legal certainty.

The cases concerned, among other issues, limitation periods for tax liabilities, the electronic service of tax decisions, VAT penalties, interest on tax arrears and the possibility of retrospectively amending tax returns.

In several proceedings, the courts accepted MDDP’s arguments based on the EU principle of proportionality and the need to provide taxpayers with appropriate procedural safeguards.

Some of these judgments have already led to changes in the practices of tax authorities and established new standards for the conduct of tax proceedings.

Contributing to a better tax dispute resolution system

The work of the MDDP team extends beyond representing clients in court proceedings.

In 2025, MDDP, together with the Lewiatan Confederation, published Poland’s first comprehensive report on tax audits.

The publication initiated a nationwide debate on the practices of tax authorities, the effectiveness of tax audits and the scope of protection available to taxpayers.

The report’s findings have also made an important contribution to the discussion on the need for legislative and procedural changes in the area of tax audits and disputes.

Experience that shapes the law

MDDP’s Tax Litigation & Disputes team combines litigation experience, technical expertise and a strategic approach to tax disputes.

Its experts represent clients at every stage of proceedings – from tax audits and verification activities, through proceedings before tax authorities, to cases before national and European courts.

The recognition at the ITR EMEA Tax Awards 2026 highlights the MDDP team’s role in handling precedent-setting disputes, strengthening the position of taxpayers and setting new directions for the application of tax law.
