Maryland Power of Attorney for tax payers: form change

On January 1, 2017, the Maryland Comptroller’s Office changed its policy and will now only accept two forms for Power of Attorney for tax purposes. These are:

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

Residents should note that when filing state taxes in Maryland, the Comptroller’s office will no longer accept the following Power of Attorney forms, which were valid through December 31, 2016:

  • Federal Form 2848 (Power of Attorney & Declaration of Representative)
  • Federal Form 8821 (Tax Information Authorization)
  • Federal Form 8655 (Reporting Agent Authorization)

While the Comptroller’s office will continue to accept a durable Power of Attorney for MD tax purposes, Form 548 does not replace a durable Power of Attorney, nor any other form of legal representation recognized by Maryland law.
