Montana Income Taxes and MT State Tax Forms
Montana
"The Treasure State
eFile.com makes it easy for you to prepare and e-file your IRS and Montana State Tax Return (e.g resident, nonresident, or part-year resident returns). Be aware that the IRS and the Montana State Tax Agency require you to e-file a Federal Income Tax Return at the same time you e-file a Montana State Tax Return. This is an IRS and Montana State Tax Agency policy, not an eFile.com policy. Thus, you technically cannot e-File anywhere - not just eFile.com - a Montana Tax Return without also e-filing the associated IRS Tax Return. But there is good news, please read on.
Detailed instructions on how you can only prepare and mail in - not eFile - a Montana 2020 Tax Return - here via eFile.com. You can complete and sign the 2020 tax return forms online here on eFile, before you download, print and mail them to the state tax agency. The address is listed on the form. The IRS mailing address can be looked up here.
Prepare only a MT State Return without an IRS return.

Montana Tax Facts, Information
Montana Tax Information and Contacts
Though Montana does not have a sales tax at the state nor local level, some communities have resort and local option taxes as their funding source. The purpose for these taxes is to allow places with high numbers of visitors, but relatively few residents, to collect local infrastructure costs without overburdening local citizens. The maximum rate of the resort tax is 3%. At least 5% of collected revenue must offset property taxes.
Montana Tax Fact
Montana's Medical Marijuana Act greatly affects state income taxes. Qualifying patients are not entitled to a deduction on their tax return for the cost of growing or purchasing marijuana, even if they own a valid medical marijuana card that allow them to grow or possess the drug for medical purposes. The only drugs that are allowed as an itemized deduction for medical expenses are those that a physician prescribes (insulin being the exception). Federal law prohibits a physician from prescribing marijuana, even in states where medical marijuana is legal. Therefore, under the MT Medical Marijuana Act, physicians do not prescribe the drug, but only certify the qualifying patient for it.
