About Us
One team across three countries since 1996
Cross-border accounting and advisory expertise connecting Turkey, Hungary and the United Kingdom.
Our Manifesto
A strategic partner behind the numbers
TBCAS is not a bookkeeping firm that only keeps score. We read the story behind the numbers and bring a strategic partner to your management decisions.
With three decades of experience and a network across three countries, we walk alongside Turkish entrepreneurs on their international journey. Istanbul's dynamic economy, Hungary's gateway to Europe and London's global financial centre — we unite three points under one discipline.
Our Story
A vision that began in London, 2005
Founded in 1996 in Istanbul as an accountancy practice, TBCAS took on a new dimension when our founder Murat Zengin earned his Chartered Certified Accountant title in London in 2005. Cross-border advisory became our primary focus from that moment on.
In 2012 we opened our office in Kaposvár and expanded into Central Europe. Today, with over 30 years of know-how, we deliver end-to-end solutions for SMEs, e-commerce entrepreneurs and family businesses.
Our Values
How we work
Transparency
A reason for every decision, a source for every number. We explain what we do and why.
Long-term Relationship
Not one-off transactions — decade-long partnerships. 80% of our clients have been with us for 5+ years.
Technical Depth
Rather than generic answers, solutions grounded in the detail of legislation. Each country has its own nuance.
Quiet Discipline
No flashy promises — regular results. Every month, every quarter, every year — the same quality.
Our Founder
Murat Zengin
Founder & Chartered Certified Accountant
A graduate of Istanbul University Business School, Murat Zengin has been working in the accounting and tax world since 1996. He earned the Chartered Certified Accountant (ACCA) designation in London in 2005, laying the framework for his international expertise.
Fluent in Turkish, English and Hungarian, Murat is an expert in tax treaties and corporate structuring between the three countries. He personally runs our Kaposvár office and plays a direct role in strategic client relationships.
"Opening offices in three countries isn't enough — you have to internalise the legislation, the culture and the way business is done. That's exactly where TBCAS is different."
Our Team
A core team of specialists across three countries
Our team consists of accountants, tax advisors and legal support specialists fluent in each country's local legislation. We operate in Turkish, English and Hungarian.
