2019 Pass-through Entity Annual Composite and Informational Tax Returns beign filed on extension are due on September 15, 2020.
Since Tax Year 2017, you no longer need to make a payment by the due date of the return to get an extension to file.
All taxpayers can enjoy a six-month automatic extension. As a result, the department removed the extension checkbox and the extension line on Form 2.
However, the automatic extension to file is not an extension to pay.
If you pay all or part of your taxes after April 15, 2019, you will have to pay interest at a 5 percent rate on that amount.
If you file on extension, you may still want to make a payment by April 15 to reduce the interest you will owe.
When making such payments:
- Choose “Payment with Return” on the Montana Individual Income Tax Payment Voucher or “Return Payment” if you pay via E-check, and
- Report this payment on line 7 of the “Other Payments and Refundable Credits Schedule” when you file your return.
Individual income tax returns are due on April 17. If you are not ready to file by that date, you may take advantage of Montana’s automatic extension and file by October 15.
In prior years, a valid extension required a payment of 100% of the taxes owed in the previous year or 90% of the taxes due for the current year by the original due date of the return, usually April 15.
Beginning with tax year 2017, individual taxpayers are granted an automatic extension of time to file of up to six months. You do not have to file any form or pay any amount to qualify for the extension.
An extension to file the return is still not an extension to pay.
Although it is not required to receive an extension, individuals may still pay any additional tax due (after accounting for estimated payments and withholding) by the original due date of the return to avoid applicable late payment penalty and interest.
