About the Founder

John F. Copenhagen, EA

John F. Copenhagen retired from the Internal Revenue Service after 37 years of distinguished service, holding roles from Contact Representative to Internal Revenue Agent to Supervisory Revenue Agent — earning awards from the Agency, the National Treasury Employees Union, and local community organizations.

During his IRS career, John coordinated examination projects across industries including construction, medical, restaurants, money service businesses, and more. He coauthored parts of the Internal Revenue Manual, wrote white papers for Compliance Initiative Projects, oversaw preparer penalty cases, and served as a government witness in civil and criminal cases — several of which were highlighted in Forbes.

After retiring, John became an Enrolled Agent and founded Strategic Tax Authority LLC to bring his insider expertise directly to American taxpayers. The firm's mission: educate, empower, and advocate — so every client has a knowledgeable ally in their corner.

Client Stories

Real Results for Real People

★★★★★
John was able to get my refund of over $360,000 released within 6 months of deciphering the IRS maze which took my former accountant and attorney over 6 years and they still were not able to get it resolved. His perseverance and tenacity paid off greatly even after I gave up. I would recommend John for anyone facing a difficult situation with the IRS.

★★★★★
A must-read for anyone facing an audit — whether it's a simple notice or a complex field examination. The strategies are spot-on, but what stands out most is the tone: calm, clear, and reassuring. It feels like having an expert sitting right next to you. John understands the IRS procedures like the back of his hand.

★★★★★
I was always intimidated when I opened my mail because I was so far in debt with the IRS for back taxes, but John gave me the roadmap I needed. Dealing with Revenue Officers was hard because of office closures, but John assisted me in locating my assigned RO — my account is now in Currently Non-Collectible status. Thank you, John, for everything.

★★★★★
John has saved me thousands in failure-to-file and failure-to-pay penalties on my corporation. After working with him on penalty abatement, I realized exactly where my previous tax preparer went wrong and how to fix it. John's personal assistance helped me respond to the IRS in a way that actually got results.

★★★★★
Before working with John, audits seemed mysterious and confusing. Now I have a clear understanding of how the IRS approaches audits, what prompts specific inquiries, and how to document my perspective. If you want a fair advantage, this is the place to begin. You don't want to gamble with the IRS.

John demystifies a process that terrifies most taxpayers. He breaks everything down into plain English and gives you the confidence to take control of your audit rather than letting the IRS control you. His approach is empowering, practical, and surprisingly easy to follow.

Frequently Asked Questions

What is an Enrolled Agent?

An Enrolled Agent (EA) is a federally licensed tax practitioner authorized by the U.S. Department of the Treasury to represent taxpayers before the IRS.
