Montana Filing Separately When Married
When married individuals choose to file separately for Montana state income tax purposes, they must follow specific rules and procedures set by the Montana Department of Revenue. Filing separately means each spouse files their own Montana Individual Income Tax Return (Form 2) and reports their own income, deductions, and credits independently.
Key Considerations for Married Filing Separately
- Residency Status Matters: If one spouse is a Montana resident and the other is not (mixed residency), both must complete lines 1 through 12 on Form 2. The net long-term capital gains tax (line 11) and ordinary income tax (line 12) are then used to calculate total Montana tax liability on Schedule II, Tax on Montana Source Income.
- Spouse Information Required: If filing separately, you must mark the box for "Married Filing Separately" and enter your spouse’s name and Social Security Number in the designated space.
- Income Reporting: Each spouse reports their own adjusted gross income separately. You cannot assign income between spouses. This applies even if you file a joint federal return.
- Refunds: If both spouses are entitled to refunds, the Montana Department of Revenue will issue two separate checks or electronic payments.
Special Rules for Net Long-Term Capital Gains
Montana imposes a separate tax on net long-term capital gains. When filing separately, each spouse calculates their own net long-term capital gains tax based on their individual gains. The filing status limits for net long-term capital gains tax are:
- Single, married filing separately, estates, and trusts: $47,500
- Married filing jointly and qualifying surviving spouse: $95,000
- Head of household: $71,250
Important Notes
- Married couples who file separately on the same form are still considered to be submitting two separate tax returns.
- If only part of your income is exempt from Montana income tax (e.g., tribal income), you may need to complete Form ETM (Enrolled Tribal Member Exempt Income Certification and Return) for each spouse claiming exempt income.
- Ensure you include all required schedules and supporting documentation when filing.
