Minnesota taxes for self-employed workers in 2026

If you're self-employed in Minnesota, nothing is being withheld, so you'll usually need to pay during the year.

Minnesota estimated tax payments for 2026

You have to make estimated payments if you expect to owe $500 or more in Minnesota income tax after withholding and refundable credits. Self-employment income is one of the state's own examples.

The form is Form M14, and you can generally pay online instead of mailing it.

Your federal tax comes first

Wherever you live, self-employed income is subject to federal income tax and self-employment tax. A single filer with $60,000 of net profit and no other income owes about $12,037 in federal tax for 2026, or 20% of profit, before any state or local tax.

Federal estimated payments are due April 15, June 15, and September 15, 2026, and January 15, 2027. Use our 1099 tax calculator to run your own numbers.
