  • Extension Mailing Address:
    You can be granted an extension of time for filing your Montana income tax return if you meet both of the following requirements: 1. By April 15, 2008, you have applied to the Internal Revenue Service by filing federal Form 4868 for an automatic six-month extension to file your federal income tax return. 2. You have paid 90% of your 2007 Montana income tax liability or 100% of your 2006 Montana income tax liability through your estimated tax payments, your withholding tax, or a combination of both your estimated and withholding tax payments. Even though you have applied for an automatic six-month federal extension, this does not guarantee that you have a Montana extension unless you have met one of the requirements listed in number 2 above on or before April 15, 2008.
