Wagner Accounting & Tax Service, Inc.


Wagner Accounting & Tax Service was founded by David Wagner in 1973 to provide Accounting and Tax Preparation services for the Tri-State area. For many years, this family firm operated at the corner of University and Irving streets in Dubuque, Iowa. Wagner Accounting & Tax Service relocated to its present Dubuque location on Century Drive in 1985. In 1987, Wagner Accounting and Tax Service expanded to a second office in Maquoketa, Iowa. Thomas Wagner joined the firm in 1997 to continue the tradition of service to the greater Dubuque and Maquoketa areas. The firm incorporated into Wagner Accounting & Tax Service, Inc. in 2004.

In 2019, we acquired One Stop Tax & Accounting Service. Founded by Delbert Winner in 1969, and operated by Sharon Winner for many years, the One Stop team has joined our offices in Dubuque and Maquoketa.
