Extension rules
Extension type: Automatic with Federal · Form PV
Follow the instructions on Form PV (extension payment voucher) to request an automatic extension on filing your return. Filing this form extends the time to file your return, but does not extend the time to pay your taxes. Payment of the expected tax due is required with Form PV by April 15, 2024. If no tax is due and you requested a federal extension, you do not need to file Form PV or take any other action to obtain an automatic six month extension. Only submit Form PV if there is tax due.
If you owe tax: However, if you owe a tax liability you must file Form PV by April 15th along with your estimated tax payment
If you owe $0: If you do not owe a tax liability then you are granted a 6-month extension with your Federal tax extension.
You must file a request and make a payment by the original tax deadline (April 15) to grant yourself that extra 6 months to file and avoid penalties. Maryland has streamlined this process. You will use Form PV (Payment Voucher) to complete this transaction.
