Montana Filing Requirements
Montana residents and nonresidents are required to file an individual income tax return if they have Montana-source income. The primary form used for this purpose is Form 2 – Individual Income Tax Return. This form is used to report income, claim deductions and credits, and calculate tax liability for the state of Montana.
Who Must File?
- Residents of Montana who earned income during the tax year.
- Nonresidents and part-year residents who earned income from Montana sources.
- Individuals who have Montana-source income, regardless of whether they are residents or not.
Filing Methods
Montana offers both electronic and paper filing options:
- E-filing: Recommended for faster and safer processing. The system typically opens for e-filing in late January. You can use the TransAction Portal (TAP) for electronic submissions.
- Paper filing: If filing by mail, you must complete your federal Form 1040 first. Then, complete Montana Form 2 using blue or black ink. Mail pages 1 and 2 along with any required schedules and your federal return.
Required Forms and Schedules
- Form 2: The main form for individual income tax returns. Includes instructions for calculating tax liability based on Montana-source income.
- Schedule I: Used to report Montana adjustments, including exempt income and deductions.
- Form ETM: Required to report exempt income, which must be entered on Schedule I, line 13, and Form 2, line 5.
- Form EST-I: Used for calculating estimated tax payments, including ordinary income and net long-term capital gains tax for Montana-source income.
Tax Calculation for Nonresidents and Part-Year Residents
Nonresidents and part-year residents must calculate their tax liability based on their Montana-source income. This involves:
- Determining the ratio of Montana-source income to total federal income.
- Multiplying this ratio by the federal tax liability to determine the Montana tax on ordinary income.
- Calculating a separate ratio for net long-term capital gains and applying it to the federal capital gains tax.
- Adding both components to determine total tax on Montana-source income.
Important Deadlines
The deadline for filing Montana individual income tax returns is typically April 15th, aligning with the federal deadline. However, if you are filing a paper return, ensure you account for mailing time.
