How the 2026 numbers are calculated
- Net profit is your 1099 income minus deductible business expenses (Schedule C).
- Self-employment tax is 15.3% of 92.35% of net profit: 12.4% Social Security on the first $184,500 of combined wages and net earnings, plus 2.9% Medicare on all of it. An extra 0.9% Medicare tax applies above $200,000 ($250,000 married filing jointly).
- Adjusted gross income is net profit plus any W-2 wages, minus half of the self-employment tax.
- The standard deduction ($16,100 single, $32,200 married filing jointly, $24,150 head of household) and the 20% qualified business income deduction reduce taxable income. The QBI deduction starts phasing out above $201,750 of taxable income ($403,500 joint).
- Federal income tax is applied to what is left using the 2026 brackets for your filing status.
- The child tax credit ($2,200 per child under 17, $500 per other dependent) reduces income tax; up to $1,700 per child is refundable and can offset self-employment tax.
- The earned income credit for filers with children — up to $4,427 with one child, $7,316 with two, $8,231 with three or more — is fully refundable and phases out above $23,890 of income ($31,160 joint).
- Minnesota income tax: calculated under the state's own rules, described below.
Minnesota and self-employment income
Minnesota has four brackets from 5.35% to 9.85%, indexed each year (the 5.35% band covers the first $33,310 single / $48,700 joint in 2026). The standard deduction ($15,300 single / $30,600 joint / $23,000 head of household for 2026) is a little above the federal one and shrinks for incomes over about $244,000, and each dependent is worth a $5,300 exemption that phases out above roughly $245,000 single / $367,000 joint. Minnesota starts from federal AGI, so the deduction for half of self-employment tax carries over; the QBI deduction does not.
Minnesota rules used by this calculator (2026)
- Minnesota applies 4 brackets from 5.35% to 9.85% for 2026.
- Standard deduction: $15,300 single, $30,600 married filing jointly, $23,000 head of household.
- Each dependent adds a $5,300 deduction.
- The dependent deduction shrinks by 2% for every $2,500 of income over $244,500 ($366,700 joint).
- The standard deduction is reduced for incomes above $244,400, by up to 80%.
- A refundable working family credit of 4% of the first $9,690 of earned income plus $1,800 per qualifying child, together reduced by 12% of income over $32,680 ($38,770 joint); the calculator applies it.
- Minnesota starts from federal AGI, so the deductible half of self-employment tax reduces state income as well.
- Minnesota has no city or county income taxes.
What a Minnesota freelancer may still owe
- Minnesota requires estimated payments (Form M14 / online) when you expect to owe $500 or more.
- There is no city or county income tax. Applied here: the refundable Minnesota child tax credit ($1,800 per child in 2026) and working family credit (4% of the first $9,690 of earned income), which phase out together at 12% of income over about $32,680 single / $38,770 joint — a joint family at $50,000 with two children gets a refund of roughly $2,400 rather than owing tax. The add-on for qualifying children 18 and over is not included.
Quarterly estimated tax deadlines (2026)
If you expect to owe $1,000 or more of federal tax for the year, the IRS expects four estimated payments (Form 1040-ES). Minnesota runs its own estimated-payment schedule with its own threshold (see above); the calculator's per-quarter figure combines federal and state so you can set aside one amount.
- Federal payment 1: April 15, 2026
- Federal payment 2: June 15, 2026
- Federal payment 3: September 15, 2026
- Federal payment 4: January 15, 2027
The calculator splits your total into four equal payments. To avoid an underpayment penalty you can instead pay 100% of last year's total tax (110% if your prior-year AGI was over $150,000) spread across the four dates.
Common questions
Does Minnesota tax self-employment income differently from wages?
For state income tax, net profit from self-employment is ordinary income like wages. The self-employment tax itself is federal only; Minnesota does not add a state equivalent.
Is half of self-employment tax really deductible?
Yes, for federal tax. The employer-equivalent half is an adjustment to income on Schedule 1, which lowers your AGI and therefore your federal income tax. It does not reduce the self-employment tax itself.
Does an LLC change these numbers?
A single-member LLC taxed as a sole proprietorship pays exactly what this calculator shows. Electing S-corporation status changes the math (salary plus distributions) and is outside this tool's scope.
What if I moved to Minnesota during the year?
Income earned while you were a resident of another state is taxable there under that state's rules. This calculator assumes all income was earned as a Minnesota resident.
