What We Do

About Barbara Aho, EA.

Oaktree Tax Office is owned and managed by Barbara Aho. Barbara started her career in accounting and tax preparation in 1980, working first for H & R Block. In 1988 she passed the Treasury Department test and became an Enrolled Agent. Barbara ran her own business for many years before joining Bob Wallis to form Wallis & Aho Enrolled Agents in 1993 where she remained until she formed Oak Tree Tax Office in 2012, in Lantana, Florida. Her current office is located at 300 S. Dixie Highway, Suite B, in Lantana, Florida. The business has continued to see strong growth since its founding.

Barbara is a member of The National Society of Enrolled Agents (NAEA), Florida Society of Enrolled Agents and the Palm Beach Chapter of FSEA, as well as NSTP, National Society of Tax Practitioners.

Barbara especially enjoys doing tax returns because she views every client that comes through the door as a unique individual, with his or her own special challenges. And Barbara loves the challenge – that’s what drives her! Every tax return is like solving a puzzle to Barbara. She also believes in the value of relationships and views every client relationship like a mini partnership .

We are Enrolled Agents (or EAs).

What exactly does that mean? An Enrolled Agent is a special type of tax advisor who is a federally authorized tax practitioner empowered by the U.S. Department of the Treasury. Enrolled Agents represent taxpayers before the Internal Revenue Service (IRS) regarding tax issues that may include audits, collections and/or appeals.

The Enrolled agent status is the highest credential awarded by the IRS.

The EA credential is recognized across all 50 U.S. states. EAs are like attorneys and certified public accountants (CPAs) in that they are empowered by the Department of the Treasury to represent taxpayers before the IRS. But the roll of the Enrolled Agent is unique. According to the National Association of Enrolled Agents, there are approximately 48,000 practicing EAs in the United States.
