Power of Attorney

The Comptroller's Office will no longer accept the federal Form 2848 or federal Form 8821 as power of attorney forms for Maryland tax purposes.

Please use one of the following forms:

Maryland Form 548 (Power of Attorney)
Maryland Form 548 Instructions
Maryland Form 548P (Reporting Agent Authorization)

We will continue to accept a durable power of attorney or any other power of attorney form authorized by Maryland law.

The completed Maryland Form 548 should include all identifying information for the taxpayer including:

  • Name(s)
  • Address
  • Social Security number(s)
  • Signature(s)
  • Date

The tax representative or appointed authority authorized to have power of attorney and to receive and inspect confidential tax information for the taxpayer must specify on the form the representative's name, mailing address, daytime telephone number, signature and designation item number (1-10). The Maryland Form 548 must also be filed with government-issued identification for the taxpayer (not the representative) unless the representative's designation is item number 1, 2 or 3.

The tax matters to be discussed by the taxpayer's representative with power of attorney must include the following information:

  • Type of Maryland tax (income, employment)
  • Maryland tax form number (502, MW506)
  • Year(s) or period(s) covered

If the power of attorney form does not include all the information as instructed it will not be accepted.

The power of attorney form shall be valid until superseded, revoked or by the death of the taxpayer(s) or representative(s).

Tax information can be disclosed to the appropriate party possessing power of attorney if the "Check Here" box on the appropriate form (Form 502, Form 505, etc.) has been marked. This authority extends to the estimated payments made for the subsequent tax year.

There is no such thing as a "Verbal POA". If a taxpayer calls and their representative is present the taxpayer can give permission for the representative to speak to us at that time. However, the approval is for that phone call at that time only.

Volunteer Income Tax Preparation Organizations V.I.T.A/A.A.R.P/T.C.E

Volunteers can use Maryland Form 548 and Maryland Form 548P with no PTIN. All information will still be required in order to accept the POA. They should clearly indicate on the form the volunteer organization with whom they are affiliated.

Power of attorney forms can be mailed, faxed or scanned and e-mailed.

If mailing the forms they can be sent to:

Comptroller of Maryland
Revenue Administration Division
P.O. Box 1829
Attn: POA
Annapolis, Maryland 21404-1829

If faxing the forms they can be faxed to 410-260-6213.

If scanning and e-mailing the forms they can be e-mailed to RADPOA@marylandtaxes.gov
