Montana taxable income
In 2024, Montana taxpayers will use their federal taxable income as the starting point for calculating their Montana taxable income. Previously, Montana used federal adjusted gross income (AGI) as the base, which often required recalculating certain items.
Since Montana’s taxable income is now directly based on federal taxable income, income that is not taxable at the federal level but is included in Montana taxes might need to be added back in. Examples include:
- Interest and mutual fund dividends from state, county, or municipal bonds from other states
- Other recoveries of amounts deducted in earlier years that reduced Montana taxable income
- Taxable distributions from a Montana Medical Savings Account or a Montana first-time homebuyer savings account
- Deductions for state income tax paid that are included in federal taxable income
- Expenses used to claim a Montana income tax credit
- Farm and ranch risk management account distributions
- Title plant amortization or depreciation
- Taxes paid by an S corporation
Keep in mind that taxable Social Security income and net operating losses will still count as part of your Montana taxable income if they’re already included in your federal taxable income.
Montana 2024 changes to tax deductions and credits
As of 2024, many deductions no longer apply in Montana, including unemployment compensation and tip income for certain service industry workers. The Montana Department of Revenue has a list of repealed deductions on its website.
Montana does not have its own standard deduction as of tax year 2024. Instead, if you take the federal standard deduction, you can use the same deduction on your Montana taxable income. If you itemize deductions on your federal income tax return, you must remove up to $10,000 ($5,000 for married filing separately) of state income tax claimed on your federal return (only to the extent that it does not reduce your deductions below your federal standard deduction).
Montana also no longer has dependent or personal exemptions. However, taxpayers 65 and older can subtract $5,500 from their federal taxable income ($11,000 for those married filing jointly). Certain military retirees may also be able to subtract some of their benefits from their taxable income.
Montana deductions that are still available for 2024 include the following:
- State income tax refunds
- Interest and mutual funds from federal bonds, notes, and obligations
- Recoveries of amounts deducted in earlier years included in federal taxable income that did not reduce Montana income tax
- Exempt tribal income
- Military salary of an active duty servicemember
- Montana Medical Savings Account deposits and earnings (up to $4,500 per taxpayer in 2024)
- 529 plan deposits
- ABLE account deposits
- Business-related expenses for purchasing recycled material
- Business expenses not included in federal taxable income due to an existing federal credit taken
- Certain expenses for cannabis businesses
- Tier I and II Railroad Retirement Benefits
