Melissa Ryan, CPA

With more than a decade of experience in the accounting field, I advise clients on state and local tax compliance across a wide range of industries — including manufacturing, professional services, and software and technology. As your business grows and expands into new jurisdictions, I act as a trusted partner, helping you navigate an increasingly complex and ever-changing compliance landscape.

I take a proactive, detail-driven approach — prioritizing the timely completion of annual return filings, state nexus studies, and other critical compliance activities. My work often involves evaluating sales sourcing rules, including throwback considerations for tangible personal property, to help organizations accurately reflect activity across states.

I enjoy solving nuanced sales sourcing challenges and addressing employee-related exposure for remote workforces, areas that continue to grow in relevance. I also advocate on behalf of taxpayers in interactions with various state jurisdictions nationwide, helping them meet obligations and protect their interests. 

Prior to joining MGO, I began my career with a Big Four firm. Moving on to a regional firm, I was privileged to focus on the state and local taxes for large multistate businesses.
