How it
all began

Since arriving in Israel in the year 2000, Miriam Konstam worked with various US based clients at a high-level accounting firm in Israel.

But as the high-tech industry developed, in her day-to-day work, she saw that local tech startups continuously faced a unique set of challenges.

So, with the insights she gained in watching their struggles, she invested a great deal of time and energy in developing an approach to directly meet their specific needs.


I realized that as US accountants located in Israel, we are uniquely positioned to take the burden of US tax navigation off their shoulders.”

By giving these fast-moving companies guided support on an ongoing basis, she could ensure that their filings and compliance would always be impeccable.

This way, they would be 100% prepared for anything their company would face in the future. From audits through to due diligence – without the usual stress and overwhelm.

Miriam Konstam felt that she could best deliver this unique approach to clients by running her own firm. And so she left her position and MK Tax was born.

MK Tax is flourishing as a boutique tax firm with a robust team of 20 employees and more than 200 satisfied clients.

Yet each and every client feels like they’re a truly valued customer.


American-style service, just 27 minutes from Tel-Aviv

Working with US-based tax firms comes with frustrating time differences, culture clashes, and inevitable misunderstandings. But at MK Tax, we understand both worlds.

From our Jerusalem offices, we provide American expertise and American-grade professional customer service. Along with a deep understanding of the Israeli mentality and your needs as an agile startup.
