What Does an Enrolled Agent Do?
Federal EA enrollment provides unlimited practice rights before the IRS, subject to proper authorization. State-agency representation has separate credential and authorization rules; verify the requirements for each state and matter rather than assuming federal enrollment covers them all.

Choosing an Enrolled Agent for Multistate Work
Ask about the professional’s experience in the relevant states and agree on the filings and monitoring included in the engagement. Specify review frequency and notification responsibilities; continuous updates should not be assumed from an EA credential or online reviews.
FAQs
What is the difference between an Enrolled Agent and a CPA for multistate tax work?
Enrolled Agents are federally authorized by the Internal Revenue Service (IRS) to represent taxpayers and possess specialized expertise specifically in federal tax law and related matters, making them uniquely qualified to handle complex tax issues and disputes. On the other hand, Certified Public Accountants (CPAs) often have a broader range of professional services they can provide, which may include auditing, financial planning, consulting, and advisory services, depending on the accounting firm they work for and the specific regulations of the state in which they are licensed to practice.
Do I need multistate tax filings if I run a remote/online business?
It is quite possible that you may have obligations such as sales tax nexus, income tax liabilities, and withholding responsibilities. These requirements can vary significantly depending on the specific locations where your business conducts operations or where your customers are based. Understanding these factors is important because tax laws and regulations differ by jurisdiction, and your responsibilities will be influenced by where you have a physical presence or economic connections through your customers.
What happens if I’m audited in multiple states?
Federal EA enrollment provides unlimited practice rights before the IRS, subject to proper authorization. State-agency representation has separate credential and authorization rules; verify the requirements for each state and matter rather than assuming federal enrollment covers them all.
Discuss Your Multistate Tax Records
Henriquez Accounting supports individuals and businesses with tax prep & representation, bookkeeping, and business consulting.
Before a multistate consultation, list the states where you operate, have workers or property, and receive customer revenue. Gather prior returns and notices, and identify any unfiled periods. Ask which registrations, returns and representation matters are included. The IRS preparer credentials guide describes federal practice qualifications; state requirements need separate review.
Keep a written list of unresolved jurisdiction questions and who will address them. A multistate engagement should identify the information needed, review dates and client responsibilities. Confirm how changes such as a new worker location or business activity will be communicated, rather than assuming that every change is automatically monitored.
