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.
