Your numbers

Answer each Yes/No question, then fill in the amounts that appear. Use 0 only when an amount is truly zero. Want to see how it works first? Load example numbers below.

Does your situation fit the list below?

If you have investment gains, rental income, other tax credits, tips or overtime pay, itemized deductions, or you or your spouse are 65 or older, answer No: the Household tax planner asks about all of those and starts with the numbers you enter here.

This calculator works if: you lived in Minnesota all of 2026; you (and your spouse) are under 65 and not blind; no one else can claim you as a dependent; you run one business yourself (sole proprietor or single-member LLC) and work in it; and your total income after adjustments (AGI) is under $200,000 ($100,000 if married filing separately). It handles: any filing status, job pay for you and your spouse, bank interest, children and other dependents, health insurance you pay yourself, and business retirement savings. For investment gains, rentals, itemized deductions, child care and other credits, or the tips, overtime and senior deductions, use the Household tax planner; it starts with the numbers you enter here.
Not sure? Most unmarried people file Single. Married couples usually file together. Head of household is for an unmarried person who pays for the home where a child or other dependent lives.
Profit is what you bring in minus your business costs, for the whole year. For example, $95,000 in sales minus $15,000 in costs is 80,000. Not sure? Take your profit so far this year and add what you expect for the rest of the year.
Only the part of this year’s profit you have not earned yet. For example, 15,000. Enter 0 if the year’s profit is already earned. We use it to suggest what share to set aside.
Your answer shows what to pay the IRS and Minnesota on that date, including any amount an earlier date fell short, and a schedule of all four dates. Dates already past aren’t offered.
Do you or your spouse also get paid from a job (a W-2)?

Have your latest pay stub or last year’s W-2 handy.

Will you earn bank interest in 2026?
Will you claim any children or other dependents?

Children under 17 get a federal credit of up to $2,200 each; other dependents $500. Minnesota also takes $5,300 off your income for each dependent.

Do you pay for your own health insurance?

Self-employed people can deduct premiums they pay themselves. Not insurance through a job, yours or your spouse’s.

Will you put money into a retirement plan for this business in 2026?

A SEP IRA, SIMPLE IRA or solo 401(k). Pre-tax money lowers your tax; Roth money doesn’t.

Will a job take federal or Minnesota income tax out of your pay?
Have you already made any 2026 estimated tax payments?
Have you already set money aside for 2026 taxes?
Do you want to use last year’s tax to set a safe payment amount?

Paying at least last year’s total tax (110% if your 2025 AGI was over $150,000) usually avoids an underpayment penalty, even if you owe more this year. Answer Yes only if you filed a 2025 return that covered all 12 months. Have your 2025 Form 1040 and Form M1 handy.
