Can I pay by credit card?

You can pay your Maryland tax with a credit card, using VISA, MasterCard, American Express or Discover. If you file electronically by April 17, you have until April 30 to make your electronic payment. This service applies to taxes owed for the current year or any back year (if you have a bill). You can make your payment online at Official Payments Corp or over the phone by calling 1-800-2PAYTAX (1-800-272-9829). The phone option is available only to taxpayers who filed a previous year's Maryland tax return. For more information, see Paying Maryland Taxes with a Credit Card.
