Montana Income Taxes and MT State Tax Forms

"The Treasure State
Montana State Income Tax Return forms for Tax Year 2018 (Jan. 1 - Dec. 31, 2018) can be e-Filed together with an IRS Income Tax Return until October 15, 2019. In January 2020, you can e-File Tax Year 2019.
eFile.com makes it easy for you to e-file your IRS and Montana State Tax Return (e.g resident, nonresident, or part-year resident returns). However, the IRS and the respective State Tax Agencies require you to e-file a Federal Income Tax Return at the same time you e-file a State Tax Return. This is not an eFile.com policy but an IRS and State Agency policy. Therefore, you cannot e-File a Montana Tax Return anywhere - not just eFile.com - without also e-filing the associated IRS Tax Return. However, please read on for good news.
Find detailed instructions on how you can only prepare and mail in - not eFile - a Montana 2018 Tax Return - here via eFile.com. However, you must download/print and sign the forms and mail them to the Tax Agency.

For Tax Year 2018 you can e-File an IRS Tax Extension by April 15, 2019 for free on eFile.com (instructions on whether you should consider a Tax Extension or not).
You do not have to file a MT state tax return extension if you need more time to file your state return. If you owe any taxes, Montana will grant you an automatic 6-month filing extension if you pay 90% of your 2018 state tax liability (or 100% of your 2018 state tax liability through your withholding tax, your estimated tax payments, or a combination of both) on or before the MT state return filing deadline.
If you cannot file your MT state tax return by April 15, 2019 follow the procedure that applies to your tax situation:
- If you are due a MT state refund: File your return by October 15, 2019. Choose e-file and direct deposit for the fastest refund.
- If you have a tax balance due: Pay the amount you owe by April 15, 2019 to avoid penalties and interest. You can pay online, by credit card, or by check with tax payment voucher Form IT. File your return by October 15, 2019. e-File your state return to ensure that the Montana Department of Revenue receives it on time.

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.
