Combining institutional quality assurance experience with federal authorization to protect and guide independent business owners.

My Background & Expertise

Austin Wyne is the Founder and Managing Director of Testimony Accounting Solutions, LLC, based in Peoria, Arizona. As an Enrolled Agent (EA)—the highest credential awarded by the Department of the Treasury—Austin holds unlimited representation rights to advocate for taxpayers before all administrative levels of the Internal Revenue Service (IRS).

Prior to founding Testimony Accounting Solutions, Austin spent a decade at Vanguard specializing in quality assurance and government regulation accuracy for complex retirement plans. In this role, he was responsible for reviewing and auditing complex plan structures to ensure total compliance with strict federal regulations.

Today, Austin leverages that deep regulatory background to level the playing field for small business owners. Whether defending a client against an aggressive IRS notice, keeping a small business 401(k) compliant, or structuring financial strategies as a Fractional CFO, Austin brings an uncompromising, audit-ready approach to every engagement.

Core Philosophy

"Business owners shouldn't have to live in fear of an IRS audit or lose sleep over complex government regulations. My job is to step in as your shield and partner—handling the regulatory burdens so you can focus entirely on growing your business with peace of mind."

Outside the Office

When the numbers are settled, I can be found spending time with my incredible wife and our three children. Faith and community are at the heart of everything we do; we are often at our church, and from time to time, you might even find me coaching kids' soccer or cheering on our local teams. Go Suns!
