Theodor Artenie is a Tax Advisor in the Bucharest office and the co-head of the firm-wide Tax service line. He is a well-known and highly ranked tax professional who draws on extensive experience and expertise gained over the last 20 years in key management positions at reputable consulting firms in Romania.

Theodor‘s main focus is VAT, having acquired deep knowledge of the subject in Romania and abroad throughout his career. He also provides assistance in most areas of taxation to clients in various industries including IT&C, real estate, industrial products, FMCG and automotive. Theodor is a member of various tax taskforces at different organisations where he works actively to improve the Romanian tax environment.

For more than 4 years we have had an excellent collaboration with Theodor Artenie from Kinstellar. I think he differentiates himself from the others by the knowledge he has of the Romanian Fiscal Code and the way he translates this knowledge into the business environment.

I had the pleasure of working on a significant project with Kinstellar's Tax department, specifically with Theodor Artenie, and I was delighted—great professionals, strong know-how, and strong recommendations. I also like their participation in public debates on new tax changes expected in the country. We can count on their suggestions.
