Our Story
How Two Paths Converged Into One Firm
For over a decade, Mohsin Ali worked his way up through CPA firms across the United States, serving as both manager and partner during his 12-year career. He prepared and reviewed thousands of tax returns, gaining a deep understanding of how the system works and where it fails business owners. Mohsin also has an entrepreneurial streak. He once won an international entrepreneurship competition in the United Kingdom and was sponsored by the UK government for a full year of mentorship and training by some of the world's leading business minds.
At the same time, Shafen Khan was building and running his own businesses. As a hands-on entrepreneur and tech-focused problem solver, he cycled through several CPAs but never found one who could think beyond compliance. Year after year, the pattern was the same: numbers filed in April, little guidance in between, and missed opportunities to plan ahead.
When Mohsin and Shafen met in 2023, the connection was instant. Mohsin brought the precision and experience of a seasoned tax strategist. Shafen brought the creativity, business instincts, and technology focus. Together, they realized that taxes don't have to be stressful or reactive — they can be strategic tools for growth.
That vision became the foundation for Tax Square. Founded in 2025, the firm blends deep tax expertise with technology-driven systems and a year-round planning approach. Mohsin leads with technical insight and strategic foresight. Shafen drives the systems, automation, and client experience that make the whole operation run.
Together, we're building more than an accounting firm. We're building a trusted partnership for entrepreneurs who want to keep more of what they earn and grow with clarity.
