We started with the belief that cost segregation shouldn’t be complicated or out of reach, but instead a powerful, practical tool every investor can use to accelerate wealth.
A Firm Committed to
Your Success
At USTAGI – U.S. Tax Advisors Group, Inc., our mission has always been simple: help real estate investors keep more of what they earn.
Founded by Joseph Viery, CSP, our firm was built on the idea that quality matters. Joseph saw too many investors missing out on tax savings because of generic, cookie-cutter reports. With a financial background and a passion for teaching, he set out to create a firm that delivers IRS-defensible studies while making the process clear and approachable.
Since 2007, Joseph and the USTAGI team have completed thousands of studies for clients across the country—on properties ranging from modest single-family rentals to large-scale commercial portfolios. Along the way, Joseph has become a trusted national voice, regularly speaking at workshops and podcasts, where he’s known for breaking down complex tax concepts into easy-to-understand strategies.
