Two names, one team
1992
Peisner Johnson opens in Dallas.
Andrew Johnson and Jerry Peisner start a firm built around state and local tax.
2018
Wayfair changes the rules.
South Dakota v. Wayfair brings economic nexus. A business can now owe sales tax in a state it has never set foot in.
2021
We focus on the judgment calls.
We narrow the practice to nexus studies, voluntary disclosure agreements, audit defense, taxability analysis, and cleaning up exposure.
Early 2025
We become The Sales Tax People.
We officially join Ampleo, and the firm takes the name clients already used.
New name. Same people on your file.
Clients kept telling us, "You're our sales tax people," so when we officially joined Ampleo in 2025, we made it our name. Your contacts stay the same, and so does the team on your account.
Meet Our Leadership Team.
