Minnesota taxes income with four graduated brackets ranging from 5.35% up to a top rate of 9.85%. Unlike flat-tax states, your income is sliced across the brackets so only the portion inside each band is taxed at that band’s rate. This calculator subtracts the correct standard deduction for your filing status, steps your taxable income through the 2024 brackets, and reports both your marginal and effective rates.
How it works
Minnesota uses progressive (marginal) brackets, so the calculation runs in three steps:
- Start with gross income. Enter your total annual income before deductions.
- Subtract a deduction. Use Minnesota’s standard deduction for your filing status, or enter itemized deductions if they are larger.
- Apply the brackets in slices. The first dollars are taxed at 5.35%, the next band at 6.80%, then 7.85%, and only income above the top threshold at 9.85%.
The formula is tax = Σ (slice_in_bracket × bracket_rate), where each slice is the portion of taxable income that falls inside that bracket. Your marginal rate is the rate on your last dollar; your effective rate is total tax divided by gross income.
Tips and example
A single filer with $80,000 of income and the 2024 standard deduction of $14,575 has $65,425 of taxable income. The first $31,690 is taxed at 5.35% ($1,695), and the remaining $33,735 falls in the 6.80% band ($2,294), for a Minnesota tax of about $3,989 — an effective rate near 5.0% on gross income even though the marginal rate is 6.80%.
This models only the state income tax. Federal tax and FICA are separate. Minnesota also offers credits — the Working Family Credit, child and dependent care credit, and K-12 education credit — that can reduce your actual liability below the figure shown here.
