Can a Connecticut CPA certificate holder sign IRS Form 2848?

IRS Form 2848 may be signed by a certified public accountant who is "duly qualified to practice as a certified public accountant" in their licensing jurisdiction.

In Connecticut, only those individuals who hold an active license to practice public accounting issued by the Connecticut State Board of Accountancy under section 20-281b or 20-281d are duly qualified to practice as certified public accountants in Connecticut. Those who hold CPA certificates, as defined by section 20-281c, but are not licensed by the board, or who hold a lapsed license, are not qualified to practice as certified public accountants; as such, they may not sign an IRS Form 2848 as a CPA.

Based on the above, Connecticut CPA certificate holders may not sign an IRS Form 2848 as a Certified Public Accountant.
