Why OnCourse exists
The tax resolution industry runs on a sales model: quote a fee on the first call, collect a retainer, then find out what the case actually is. People with real IRS problems deserve the reverse.
OnCourse Tax does the diagnostic first, writes the plan, and publishes its prices. The practitioner who signs your power of attorney is the one who talks to the IRS. The software we built to run cases, Resolyn, pulls transcripts directly from the IRS and calculates every collection alternative side by side, so the plan you get is ranked by outcome, not by what pays us most.
We also built it so that small cases pencil. A national firm will not take a $12,000 balance with three unfiled years. We will, at a price that is on the page.
Aaron Siegel
Enrolled Agent, enrolled to practice before the Internal Revenue Service. Founder of OnCourse Tax and Thrive Tax Solutions.
Before tax, I spent years in data analytics and enterprise software implementation, including public safety systems where the software had to work the first time. Before that, I was a law enforcement officer. Both taught me the same thing: find out what actually happened before you decide what to do about it. That is the diagnostic.
