About us

Zsolt Nyári

Partner

My professional career began in 2001 with international audit and consultancy companies. Before launching my own business in 2015, I spent 12 years with Mazars Kft, leaving them as a senior taxation manger. In addition to domestic and international tax consultation projects I was involved with responsibility in due diligence projects, tax audits as well as successful proceedings with domestic and international courts. With regards to the latter, I regard the biggest success of my professional career to be the VAT case (C-563/12) won at the European Court, for which I was the project initiator.

I have been delivering presentations at tax conferences for over 10 years, have written a number of professional newspaper articles and blog posts, and have been a regular lecturer at the post-graduate training of certified accountants held by the Education Centre of the Hungarian Chamber of Auditors. Besides Hungarian, I also assist my clients in English and French.

I obtained my professional experience between 2008 and 2017 with international consultation enterprises by providing various types of tax consultation for large corporations belonging to international groups and Hungarian SMEs as a tax manager and later tax director. In addition to consultation, I dealt with transfer pricing, tax surveys, and was responsible for a large number of tax duties related to auditing. I used to lead compliance groups and represented my clients successfully in the course of several comprehensive tax audits and in the statutory proceedings following.

Since 2013, I have regularly delivered presentations at tax conferences, business breakfasts, and in the framework of internal and external trainings. Since 2017, I have worked in Hungarian and English as a tax expert of K-X Consulting Kft in the elaboration of solutions for our Clients.
