About us

Mar.tax began as a local New York accounting firm with owner Mark A. Rozynski servicing his loyal clients in person for over 3 decades. He is renowned for his competitive filing rates and for maximizing client savings.

Mark's expertise stretches beyond accounting to immigration consulting for clients looking to migrate to the USA from nearly every continent. This was a process he went through in 1981 (immigrating to the USA from his native Poland) and that he became deeply familiar with. Please visit sponsorshipusa.org to learn more.

Over the years, Mark developed a loyal client base and his referrals stretched to clients all over the country. In 2020, 100% of his client base went digital. The team has now since expanded, but the level of service remains the same.
