About Us

Automated Accounting Services Inc begins its 36th filing season in 2025!

Keith A. Espinoza, EA founded Automated Accounting Services (AAS) in 1989 when he began transmitting tax returns to the IRS via electronic bulletin board.

First located near 58th and I-25, the firm was moved to 1600 Carr Street in Lakewood in 1992. It operated at this location for thirty one years, growing rapidly and buying out a few small tax and accounting firms along the way.

In 2023, following the sale of the family building, AAS moved to its current location at 5810 W 38th Ave, Suite 2 in Wheat Ridge. AAS has been a fixture in Jeffco for many years, and over that time Keith has prepared and successfully filed nearly 25,000 tax returns.

Today AAS is primarily an online company, and offers a whole range of tax preparation, planning, representation, consulting and accounting services for individuals and small businesses, and serves over 800 regular clients. Participation in continuing education courses offered by national tax and accounting associations keeps us on the leading edge of ever-changing tax laws. We have completed hundreds of hours of courses!
