How do I cancel my IFTA license if I don't need it any longer?
Remove the decals from your truck and return them, along with a written request for cancellation, to the Licensing and Registration Unit of the Comptroller of Maryland's Revenue Administration Division. If returning the decals is impractical, you may indicate the decal number(s) in your written request instead.
Mail your request (and decals, if any) to:
Comptroller of Maryland
Revenue Administration Division
Licensing and Registration Unit
P.O. Box 2999
Annapolis, MD 21404-2999
