Meet Don Zabarsky, EA

I’m Don Zabarsky, owner of Know Tax LLC. I live just outside Westerville, OH with my wife Theresa and our daughter Kiley. Our other child, Sean, is now attending college.

I started my accounting career as an income tax preparer and then began to specialize in helping people get out of trouble with tax problems. I am a member of the National Association of Enrolled Agents and have been granted the status of Fellow with the National Tax Practice Institute, which is the premier organization for those who specialize in handling tax controversies. In addition, I’ve earned the Advanced Crypto Tax Expert (ACT-E) designation, given by Crypto Tax Academy.

At Know Tax LLC, we specialize in solving tax problems for self-employed individuals and small businesses as well as anyone else with tax controversies. We file any back taxes and then negotiate with the IRS on our clients’ behalf to get them the best outcome they’re eligible for. After we solve all issues and everything is back on track, we offer yearly tax preparation and IRS record monitoring to let our clients relax with the knowledge that their tax situation is being handled competently and efficiently. I look forward to meeting you and discussing how I can help you!
