An Enrolled Agent (EA) is an individual designation provided by the Internal Revenue Service (IRS). It is one of the few designations that signify a concentration of competency in the field of taxation. Unlike CPAs, who may or may not provide tax services, Enrolled Agents specialize in taxation. Often called the “best kept secret in accounting,” Enrolled Agents provide an important and marketable service to the public, government and accounting community.

EAs are licensed by the federal government to represent taxpayers before the Internal Revenue Service and assist with tax planning and the preparation of tax returns. Because EA’s specialize in taxes and tax planning, they’re known as The Tax Professionals. Their federal designation gives them access and insight with federal and state agencies no matter where the EA practices and no matter where the taxpayer lives.

Company History

We have been in business since 1987. The business was originally initiated by the late Martin I. Knopp who was an IRS audit supervisor for over 17 years. Our office has since been successfully assisting taxpayers with their tax issues and concerns.
Since 1994, Jonathan J. Williams has been helping tax payers and trained directly under Marty Knopp. After his passing, Jonathan has remained loyal and dedicated to carrying on the tradition of servicing and assisiting clients in their tax and IRS needs.
