About MARK A STILES CPA, PLLC
You didn’t come to Thumbtack for more confusion. You came to find someone you can actually trust. We get it. Most accounting help online is either overpriced, under-delivered, or full of jargon. At MASCPA, we’re different, on purpose. Led by Mark A. Stiles, CPA, MASCPA is a virtual, full-service firm with over 20 years of experience guiding business owners just like you. We specialize in clarity, not complexity, using a proven framework called the MASCPA Box Method to connect your books to your goals, and your taxes to your peace of mind. We’re more than bookkeepers. We’re strategic partners who meet you where you are, clean up the mess (without judgment), and help you lead with financial confidence. What Makes MASCPA Different? Founder-first mindset: You’ll never be treated like a transaction. Practical strategy + clean execution: We do the books and build the plan. No jargon, no pressure, just clarity: Even if you’re behind, we can help. The Box Method: Our four-quadrant framework simplifies everything from taxes to growth planning. If you’ve been burned by cookie-cutter firms or left guessing by “cheap help,” MASCPA is your reset button. Let’s rebuild trust and move forward with real strategy, expert guidance, and total transparency.
Reviews
Mark was fantastic to work with. We had a complicated tax question involving a first time home buyer IRA withdrawal, and he understood it right away. In just one hour, he reviewed all of our documents, dug into the tax code, and gave us a clear answer. He was also quick to respond to follow-up questions over email. We were able to get a meeting the same week since our situation was urgent, and his rates were very reasonable. We really appreciated that Mark takes the time to educate his clients rather than just handling things for you. We left understanding our own situation, not just with an answer. Highly recommend.
I would like to thank Mark and his staff for the great service they provide. I had 4 years of back taxes that needed to be filled including this current year. After speaking with Mark about my needs, he explained to me the process of getting all my taxes up to date. He answered all my questions and concerns which gave me a peace of mind. The service he provided was done in a very good timely manner. I will definitely use Mark again for future tax services. I would highly recommend his services to anyone that is need of professional tax services.
