About

Aaron Siegel is an Enrolled Agent, enrolled to practice before the Internal Revenue Service, an NTPI Fellow, and a Certified Tax Resolution Consultant. He holds an MBA.

He founded Thrive Tax Solutions, a deliberately capped tax advisory membership for creators, consultants, and S-Corporation owners, and OnCourse Tax, a tax resolution practice that publishes every fee and runs a diagnostic before quoting a case. He also builds Resolyn, the practice management software both firms run on, which pulls IRS transcripts and calculates every collection alternative side by side.

Before tax, Aaron spent years in data analytics and enterprise software implementation, including public safety and 911 systems where the software had to work the first time. That background shows up in everything he teaches: simple, repeatable systems, one source of truth, and a deep suspicion of strategy for its own sake.

He hosts the Thrive Advisor Podcast and leads the Thrive Advisor Collective, a community of small-firm tax professionals. He served on the IRS Taxpayer Advocacy Panel for Colorado and sits on the board of the Main Street Professionals program. He lives in Fort Collins, Colorado.

Why two tracks

Most tax speakers teach either the code or the business. I ended up with both because I came to tax from enterprise software, where the question was never "what is the rule" but "how do we make the rule happen every time without a hero." The technical sessions are the rule, with the math. The practice sessions are how to make it happen every time.
