General Tax Return Information
Due Date - Individual Returns - April 15, or the same as the IRS.
Extensions - Individual taxpayers are granted an automatic extension of up to six months. Taxpayers must pay any additional tax due (after accounting for estimated payments and withholding) by the original due date of the return to avoid late payment penalty and interest. An extension of time to file is not an extension of time to pay.
Driver’s License/Government Issued Photo Identification - Montana does not require this information to file the tax return.
Filing Status Information
Montana does not require the same filing status used on the federal return. In TaxSlayer Pro, returns with a federal filing status of Married Filing Jointly or Separately can change the Montana filing status.
Residency Status Information for Montana Returns
Residents: Residents are individuals who are domiciled in Montana. Individuals who maintain a permanent home in Montana, even if temporarily absent, and who have not established a residence elsewhere, are also residents. An individual who establishes Montana residency for one purpose (such as hunting or fishing license) is considered a resident for income tax purposes.
Part-year resident: Part-year residents are individuals who move into Montana or out of Montana during the year with the intention of establishing a permanent residence in the new state.
Nonresidents: Nonresidents are individuals who were not Montana residents at any time during the year.
Military Personnel/Military Spouses
Residents: Military personnel who were a Montana resident when joining the service, have not changed residency since joining the service, or have made steps to make Montana their home of residence.
Nonresidents: Nonresident military personnel living in Montana solely to comply with military orders are not Montana residents and any military compensation is not considered Montana-source income and is not taxable to Montana. Income received from any other Montana source (such as wages for civilian services performed in Montana or Montana business income) is taxable.
Military spouses: Under the Military Spouses Residency Relief Act, a military spouse’s state of residence does not change when moving to a new state to be with a service member stationed there if the residence or domicile is the same for the service member and spouse.
