About Us
We know the IRS from the inside out.
Tax Killers was founded by a former IRS Revenue Officer who spent over a decade on the other side of the table. We use that knowledge to protect our clients.
Our Story
Founded in 2004 by someone who worked for the IRS.
Robert Harmon spent 12 years as an IRS Revenue Officer — the people who show up at your door, garnish your wages, and seize your assets. He was good at his job. But he saw firsthand how many taxpayers were overwhelmed, misinformed, and taken advantage of by the very system designed to collect from them.
In 2004, he left the IRS and founded Tax Killers with a simple mission: use insider knowledge to fight for taxpayers instead of against them. He knew every program, every loophole, every negotiating tactic — and he put all of it to work for clients.
Twenty years later, Tax Killers has resolved over $50 million in tax debt for more than 15,000 clients. Our team of licensed Enrolled Agents and CPAs brings the same insider expertise to every case — no matter the size.
How We Work
Three principles we never compromise on.
Honesty First
We tell you what's realistic — not what you want to hear. If you don't qualify for a program, we say so upfront. No false promises, ever.
You Talk to Us, Not the IRS
Once you hire us, you never have to speak to the IRS again. We handle every call, letter, and negotiation on your behalf.
Results, Not Excuses
We measure our success by your outcomes — debt reduced, garnishments stopped, liens removed. That's the only metric that matters.
Our Team
Licensed professionals. Real experience.
Every Tax Killers case is handled by a licensed IRS Enrolled Agent or CPA — never a salesperson or unlicensed representative.
