No, you can’t use a regular tax preparer to represent you before the IRS. In order for a tax professional to represent you, the Form 2848, Power of Attorney (POA) must be signed and submitted to the IRS. The IRS only allows Enrolled Agents (EA), Tax Attorneys and Certified Public Accountants (CPA) to represent you before the IRS. This means that only these certified individuals can be on the POA. If your tax preparer is an EA or a CPA then they may be able to represent you before the IRS.
