Minnesota State Tax Deductions Guide

Minnesota State Tax Deductions Guide – Minnesota residents and part-year filers can significantly lower their state income tax bill through smart use of deductions, subtractions, and the standard or itemized deduction options. This Minnesota State Tax Deductions Guide breaks down everything you need to know for tax year 2025 (returns filed in 2026) and highlights updates for 2026. All information comes directly from the Minnesota Department of Revenue (DOR) and official sources.

Whether you’re a single filer, married couple, head of household, or retiree, understanding these rules helps you avoid overpaying and claim every available break.

What Are Minnesota State Tax Deductions?

Minnesota starts with your federal adjusted gross income (AGI) from Form 1040 and then applies subtractions (deductions from federal AGI) to reach Minnesota taxable income. You then subtract either the Minnesota standard deduction or Minnesota itemized deductions (via Schedule M1SA).

  • Subtractions reduce income before the standard/itemized deduction.
  • Standard or itemized deductions are claimed on your Minnesota return even if you took the opposite on your federal return.
  • Minnesota does not allow the federal deduction for state income or sales taxes in itemized deductions.

You report subtractions and additions on Schedule M1M and itemized deductions on Schedule M1SA.

2025 Minnesota Standard Deduction Amounts

Most Minnesotans claim the standard deduction. Here are the 2025 amounts:

Filing Status Standard Deduction Additional if Blind or Age 65+ (born before Jan. 2, 1961)
Single or Married Filing Separately $14,950 +$2,000 (Single) or +$1,550 (MFS) per qualifying person
Married Filing Jointly or Qualifying Surviving Spouse $29,900 +$1,550 per qualifying spouse
Head of Household $22,500 +$2,000 if blind or age 65+

  • The standard deduction phases down for high-income taxpayers with federal AGI over $238,950 ($119,475 if Married Filing Separately).
  • Dependent exemption: $5,200 per qualifying dependent.

For tax year 2026 (returns filed in 2027): Amounts increase to $15,300 single/MFS, $30,600 joint, $23,000 HoH, and $5,300 dependent exemption.

Minnesota Itemized Deductions (Schedule M1SA)

You can itemize on your Minnesota return regardless of your federal choice. Use Schedule M1SA for these categories (with Minnesota-specific rules):

  • Medical and dental expenses — Expenses over 10% of Minnesota AGI.
  • Taxes you paid — Real estate taxes + personal property taxes (capped at $10,000 or $5,000 if MFS). No deduction for state income or sales taxes.
  • Interest you paid — Home mortgage interest and points + investment interest.
  • Charitable contributions — Cash/check and non-cash donations.
  • Casualty and theft losses — Only for federally declared disasters.
  • Unreimbursed employee business expenses — Subject to 2% AGI floor.
  • Other miscellaneous deductions.

Phaseout: Itemized deductions are reduced if federal AGI exceeds $238,950 ($119,475 MFS).
