Ondřej is a co-founder of Bříza & Trubač Attorneys at Law. In his practice, he focuses on complex tax law issues, especially representing clients in disputes with tax authorities, whether in tax proceedings or in administrative and constitutional court proceedings. He also focuses on criminal tax law, related issues of active repentance and criminal liability of legal entities. On a regular basis, he gives lectures to university students and practitioners, publishes in professional journals and co-organises conferences (e.g., Criminal Tax Law, Tax Compliance). He has co-authored commentaries on the Financial Administration Act, the Proof of Assets Act and the Civil Code, as well as a successful publication entitled „Defence Against Tax Inspection“.


Ondřej has experience with client's representation in the tax proceedings, in particular during tax controls (he is the co-author of a successful publication titled Defence Against Tax Inspection) and by means of consequent actions before administrative courts against the tax administrator's decisions, in disputes often concerning dozens of million Czech crowns. Before administrative courts he also dealt with different administrative actions from the customs law area. In connection with the Act on Criminal Liability of Legal Entities coming into force in the Czech Republic he dealt with the implementation of corresponding provisions into the internal rules of companies.

Last news

Bříza & Trubač excelled in another prestigious rating The Legal 500

Our law firm has been recommended in four areas in the current edition of The Legal 500 EMEA 2023.

Bříza & Trubač listed for the first time in the prestigious legal yearbook Chambers Europe

Analysts at Chambers and Partners, one of the world's top legal ratings, have included Bříza & Trubač in their Chambers Europe yearbook for the first time this year in the area of tax law.

The law firm Bříza & Trubač is located in Prague's Palladium at Na Poříčí 1079/3a

Since the second half of February, the law firm has a new address, which is in the Palladium shopping centre on Náměstí Republiky. The reason for the move was simple - the expansion of the office and the growing number of lawyers for whom the size of the original spaces was no longer enough.
