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 2021 Tax Return - here via eFile.com. You can complete and sign the 2021 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.

Montana Tax Extension

For Tax Year 2021, if you expect a refund or you don't owe taxes, you do not have to file a tax extension. However, if you believe you will owe taxes and can't file on time, you should take action and here are the options available for Montana:

  • If you do not owe Montana income taxes by the tax deadline of April 18, 2022, you do not have to prepare and file a MT tax extension. In case you expect a MT tax refund, you will need to file or e-File your MT tax return in order to receive your tax refund money. 
  • If you owe MT income taxes, you will either have to submit a MT tax return or extension by the April 18, 2022 tax deadline in order to avoid late filing penalties. The extension will only avoid late filing penalties until Oct. 15, 2022 Oct. 17, 2022. Note: Unless you pay all your Taxes or eFile your tax return by Oct. 15, 2022 Oct. 17, 2022, the late filing penalties will start again after Oct. 15, 2022 Oct. 17, 2022. You have the following options to file a MT tax extension:
    • Pay all or some of your Montana income taxes online via: Montana TAP. Paying your MT taxes online on time will be considered a MT tax extension and you do not have to mail in Form IT.
    • Complete Form IT, include a Check or Money Order, and mail both to the address on Form IT.
    • Even if you filed an extension, you will still need to file your MT tax return either via eFile or by paper by Oct. 15, 2022 Oct. 17, 2022.
  • Important: If you owe Montana and/or IRS income taxes and do not file an IRS and Montana tax return or extension by April 18, 2022, you will be subject to IRS and MT late filing penalties. Estimate IRS late filing, payment penalties. In addition, if you do not pay your taxes by April 18, 2022, you will be subject to late tax payment penalties. Filing an extension on time will ONLY eliminate the late filing penalties but not the late tax payment penalties. Late filing penalties are generally higher than late payment penalties, thus file something on time even if you can't pay anything on time!

The deadline to e-file an IRS extension for 2021 Tax Returns is April 18, 2022. e-File a 2020 Tax Extension for free on eFile.com. Here are instructions on whether you should consider a Tax Extension or not.

The extended IRS/Montana eFile deadline is Oct. 15, 2022 Oct. 17, 2022 - eFileIT.  Or, if you plan to file or mail-in a Montana tax return on paper, the MT Mailing Addresses are listed below.

Montana State Tax Payment Options
You can select one of these payment options either after you have e-filed or filed your 2021 Montana Tax Return. Alternatively, you can pay Montana income taxes here prior to filing (e.g in the case of an extension). Plus, you can make online Montana tax estimate payments for next tax year. If you eFiled your taxes and pay online, you do not have to send in Montana paper forms (e.g. payer tax return, extension form, or tax estimate form). 
Create an account or go to Montana TAP to submit your payment. Make sure you have a copy of your most recently filed and accepted Montana Tax Return when you create your account. If you already have an account, log into your account and select the "Return Payment (760-PMT)" option.
Check the status of your direct payment
This is a free option if you want to pay your taxes owed via your bank account.
Submit a tax payment through the state tax agency's Montana TAP. When you're on the site, select the "Make a Payment" option, then follow the on-screen prompts to enter and submit your information (e.g. SSN, Tax Year, Form Type, Filing Status).
Use this payment option if you want to pay your tax payment via your credit or debit card. There is an additional service fee added to each payment you submit with your card.
Check or Money Order with Form IT
Complete voucher Form IT and attach it to your check or money order payable to "Montana Department of Revenue". Write your Social Security number and the tax year on the check. Mail them to the Form IT address below.
Use this payment option if you wish to submit your payment via check or money order in the mail. 
Estimated Tax Payment Options
Choose one of these options: 1) Go to Montana TAP to submit your estimated payment or if you already have an account, log into your account. 2) Pay via credit or debit card through Montana TAP. Be aware that a service fee is added to each payment you submit with your card. 3) Complete voucher Form IT. Attach a check or money order for the tax period payable to "Montana Department of Revenue". Write your Social Security numbers and the tax year on the check or money order. Mail the voucher and check/money order to the Form IT address here.
Use one of these payment options if you want to submit estimated taxes rather than submit all your taxes owed at once. 
Many of these online IRS tax payment options can be used before or after you e-Filed your Income Taxes. You can pay tax extension and tax estimate payments. For estimate payments, you do not have to submit a form. Extension you can eFile on eFile.com for free.
