Why worked with an enrolled agent?

An enrolled agent is a person who has passed a comprehensive three-part test and thus is licensed by the IRS to represent taxpayers. Enrolled agent status is the highest credential the IRS awards. Individuals who obtain this status must complete 72 hours of continuing education every three years. This ensures they are up to date with tax code changes.


Working with an enrolled agent does more than ensure your taxes are prepared correctly. An enrolled agent will help you make the best financial decisions for your future and the future of your business. These individuals have proven they understand the tax code and how it applies to individuals and businesses. You can’t put a price on this kind of insight.
