Amounts to set aside, not bills: federal $3,701 for each Form 1040-ES installment (Apr 15, Jun 15, Sep 15, Jan 15). Minnesota: $757 per installment on its own schedule. For the safe-harbor amount and payments you have already made, use the quarterly calculator with these inputs.
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 below 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 — below the federal $16,100 single / $32,200 joint for 2026.
- 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.
What Minnesota costs at three levels of profit (2026)
A single filer with no dependents and no other income, taking the standard deduction. The state column is Minnesota's own tax after its deductions, exemptions and credits.
| Net profit | Federal | Minnesota | Total | Effective rate |
|---|---|---|---|---|
| $50,000 | $9,732 | $1,667 | $11,400 | 22.8% |
| $75,000 | $15,495 | $3,216 | $18,711 | 24.95% |
| $100,000 | $22,365 | $4,796 | $27,161 | 27.16% |
At $75,000 of profit, Minnesota takes $3,216 — 17.19% of the total tax bill. Change any input in the calculator above to see your own figures.
How the federal part is worked out
Net profit is 1099 income less business expenses (Schedule C). Self-employment tax is 15.3% of 92.35% of that profit — 12.4% Social Security up to $184,500 of combined wages and earnings, 2.9% Medicare on all of it. Half of that tax, the $16,100 standard deduction ($32,200 joint) and the 20% qualified business income deduction come off before the 2026 brackets are applied; the child tax credit and the earned income credit then reduce what is left, and the refundable parts can offset self-employment tax. The methodology page sets out the full sequence and every rule the calculator leaves out, including how Minnesota's figures are derived.
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 shows the federal installment and the Minnesota installment separately, and one combined amount to set aside each quarter.
The 2026 dates are April 15, 2026, June 15, 2026, September 15, 2026, January 15, 2027. The federal amount is split into four equal Form 1040-ES installments after any withholding you entered; paying 100% of last year's tax instead (110% above $150,000 of prior-year AGI) also avoids the penalty. The quarterly calculator works that out and subtracts what you have already paid, and the guide to the due dates explains the rule.
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?
For federal income tax and self-employment tax, a single-member LLC taxed as a sole proprietorship follows exactly the calculation shown here. State and local obligations can still differ: an LLC may be a taxable entity for a state's franchise, gross-receipts or excise tax, and may owe registration or licence fees a sole proprietor does not — Minnesota's are listed above. Electing S-corporation status changes the federal arithmetic too (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.
