What an Enrolled Agent can do for Illinois taxpayers
An Enrolled Agent in Illinois holds the IRS’s highest non-attorney credential and may represent any taxpayer — in Illinois or anywhere else — in any matter before the IRS. For Illinois residents, that means an EA can prepare your federal return, e-file it, respond to an IRS notice on your behalf, negotiate an installment agreement or offer in compromise, and represent you in an IRS examination or collection due process hearing. Because the credential is federal, an EA in Illinois is also fully qualified to handle returns and IRS issues for clients in any other state.
For Illinois state-tax matters, individual EAs vary in their depth of experience with the state’s personal income tax forms, sales-and-use tax filings, and property-tax appeals. Many EAs in Illinois have substantial state-tax practice; others focus exclusively on federal returns and refer state work to a CPA. Ask about state-tax experience when you contact a preparer.
