That applies to freelancers, independent contractors, gig workers, sole proprietors, and small business owners. Each of you may face three separate taxes: federal self-employment tax, federal income tax, and Minnesota income tax. Paying one doesn't cover the others.
Rates, thresholds, and deadlines change by tax year. The figures below are for tax year 2026, with returns due in 2027. Confirm them against current IRS and Minnesota Department of Revenue pages before you file.
Key Takeaways
- Self-employment tax, federal income tax, and Minnesota income tax are three separate bills.
- All three start from net profit, not total customer payments.
- Federal and Minnesota estimated payments have different thresholds and are tracked separately.
- Clean records and the right forms prevent most avoidable problems.
What Self-Employment Tax Means in Minnesota
Who Is Treated as Self-Employed?
Federal rules treat you as self-employed if you do any of the following:
- Run a business as a sole proprietor or independent contractor
- Act as a partner in a trade or business
- Own a single-member LLC (disregarded for tax purposes by default)
Part-time work and side gigs count. In the default LLC setup, the owner pays self-employment tax just like a sole proprietor.
Worker classification matters. The IRS looks at behavioral control, financial control, and the relationship between the parties. An employee gets a W-2 and has taxes withheld. A contractor receives business income and handles income and self-employment taxes personally.
What Is Federal Self-Employment Tax?
It funds Social Security and Medicare. You pay both the employee and employer halves. It's a federal tax, not a Minnesota one. According to the IRS self-employment guidance, the key 2026 figures are:
| Item | 2026 rule |
|---|---|
| Total rate | 15.3% of 92.35% of net profit |
| Social Security | 12.4%, up to a $184,500 combined earnings ceiling |
| Medicare | 2.9%, no ceiling |
| Additional Medicare | 0.9% above $200,000 (single), $250,000 (joint), or $125,000 (separate), reported on Form 8959 |
| Filing threshold | $400 of net self-employment earnings |
You can deduct half of the regular self-employment tax on Schedule 1. That lowers your adjusted gross income, but not the self-employment tax itself.
Which Income Is Used?
Start with gross receipts and subtract ordinary and necessary business expenses. The result is net profit, reported on Schedule C and carried to Schedule SE. The $400 threshold applies to net earnings, not receipts.
Side income stacks on top of a W-2 job. Your wages and your net self-employment earnings share the same Social Security ceiling.
Partnerships, farming, rentals, and S corporation shareholders follow special rules. Most real estate rent is excluded, for example, while a working S corporation shareholder must be paid reasonable wages. Get professional advice if you're in one of these groups.
How Minnesota Taxes Self-Employed Income
Minnesota Income Tax Rates and Brackets
Minnesota has no single rate. It uses graduated brackets from 5.35% to 9.85%, set by filing status and taxable income. The Minnesota Department of Revenue published the 2026 figures below. Each column shows the top of that rate's range.
| Status | 5.35% through | 6.80% through | 7.85% through | 9.85% above | Standard deduction |
|---|---|---|---|---|---|
| Single | $33,310 | $109,430 | $203,150 | $203,150 | $15,300 |
| Joint | $48,700 | $193,480 | $337,930 | $337,930 | $30,600 |
| Separate | $24,350 | $96,740 | $168,965 | $168,965 | $15,300 |
| Head of household | $41,010 | $164,800 | $270,060 | $270,060 | $23,000 |
These are marginal rates. Crossing into a higher bracket taxes only the dollars above the line at that higher rate. Your effective rate is always lower than your top rate.
How State Taxable Income Differs From Business Profit
The path runs like this: Schedule C profit, then Schedule SE, then federal adjusted gross income (AGI) on Form 1040. Minnesota's M1 starts from federal AGI, not federal taxable income. You then apply state additions and subtractions on Schedule M1M or M1MB and take Minnesota's own standard or itemized deduction.
Two differences matter most:
- QBI deduction: The federal deduction of up to 20% of qualified business income has no Minnesota equivalent.
- Bonus depreciation: Minnesota's conformity date is May 1, 2026. General bonus depreciation requires an 80% addition, recovered through subtractions over later years.
The half-SE-tax deduction, self-employed health insurance, and retirement contributions reduce federal AGI, so they flow into the Minnesota return too. Filing status, dependents, credits, and other household income also move the final bill.
Residency and Minnesota-Source Income
Full-year residents file in Minnesota if they must file federally. You're generally a resident if you spend at least 183 days in Minnesota and maintain an abode here. Any part of a day counts.
Part-year residents and nonresidents file Form M1NR. It taxes income earned while you lived in Minnesota, plus Minnesota-source business income afterward. The general filing threshold is $15,300 of Minnesota-assignable gross income.
Reciprocity agreements cover Michigan and North Dakota, not Wisconsin. Business income generally doesn't qualify for them anyway.
An Illustrative Calculation
This hypothetical example is educational, not personal tax advice.
Assumptions for this walkthrough:
- Single filer and Minnesota resident
- 2026 figures with no other income
- No QBI deduction and no credits
| Step | Amount |
|---|---|
| Gross receipts | $80,000 |
| Business expenses | $20,000 |
| Net profit | $60,000 |
| SE earnings (92.35%) | $55,410 |
| Self-employment tax (15.3%) | $8,478 |
| Half-SE deduction | $4,239 |
| Federal AGI | $55,761 |
| Federal taxable income (after $16,100 standard deduction) | $39,661 |
| Federal income tax | $4,511 |
| Minnesota taxable income (after $15,300 standard deduction) | $40,461 |
| Minnesota income tax | $2,268 |
| Total estimated tax | about $15,257 |
That's roughly 25% of net profit. The federal QBI deduction would lower the federal figure, though not the Minnesota one.
How to Calculate, Pay, and File
Annual Calculation Workflow
- Total your business income.
- Subtract eligible expenses to find net profit.
- Calculate self-employment tax on Schedule SE.
- Estimate federal taxable income and federal income tax.
- Calculate Minnesota taxable income from federal AGI plus state adjustments.
- Subtract estimated payments and any withholding.
- Identify the balance due or refund.
Run federal and Minnesota calculations separately. The same records support both returns, but the deductions, brackets, and adjustments differ.
Estimated Tax Payments
The Minnesota Department of Revenue requires estimates when you expect to owe $500 or more after withholding and refundable credits. The federal threshold is $1,000. Evaluate each threshold on its own.
| Requirement | Federal | Minnesota |
|---|---|---|
| Trigger | $1,000 expected balance | $500 expected balance |
| Safe harbor | Lesser of 90% of current-year tax or 100% of prior-year tax | 90% of current-year liability or 100% of prior-year liability |
| High-income rule | 110% of prior-year tax if AGI exceeds $150,000 | Same 110% rule above $150,000 federal AGI |
| 2026 due dates | April 15, June 15, Sept. 15; Jan. 15, 2027 | Same general dates |
| How to pay | Form 1040-ES, IRS Direct Pay | DOR e-Services or voucher |
Federal and Minnesota payments are separate obligations. A payment to one doesn't credit the other.
Filing Forms and Deadlines
- Federal: Form 1040, Schedule C, Schedule SE, Schedule 1, plus Form 8995 or 8995-A for QBI.
- Minnesota: Form M1, with M1M or M1MB for modifications and M1NR for part-year or nonresident filers.
- Entities: Partnerships file Form 1065 federally and Form M3 in Minnesota. S corporations file Form 1120-S and Form M8.
The 2026 individual deadline is April 15, 2027. Federal Form 4868 extends filing to October 15, 2027. Minnesota allows October 15 filing automatically. Neither extends the time to pay.
If you also have W-2 wages, file a new Form W-4 to raise your withholding. That can shrink or eliminate quarterly estimates.
Deductions and Recordkeeping
Common Deductions to Investigate
Only ordinary and necessary business expenses reduce profit. Personal costs never qualify. Common categories include:
- Mileage: 72.5 cents per business mile in 2026.
- Home office: the simplified method ($5 per square foot, up to 300 square feet) or actual costs on Form 8829. The space must be used regularly and exclusively for business.
- Software, supplies, advertising, phone and internet, professional fees: deductible at the business-use percentage.
- Health insurance: a Schedule 1 deduction that lowers income tax, not self-employment tax. Eligibility ends for any month you could join an employer- or spouse-subsidized plan.
- Retirement: SEP-IRA up to $72,000. Solo 401(k) employee deferrals of $24,500, with the same $72,000 overall ceiling and catch-up contributions on top.
Equipment and other capital assets may need depreciation or a Section 179 election (federal maximum $2,560,000) rather than a one-year write-off.
Records That Support Deductions
Keep invoices, receipts, bank and card statements, mileage logs, and a note of each expense's business purpose. A separate business bank account makes reconciliation far easier. It also helps you spot missed deductions and answer an IRS or state inquiry quickly.
Retention is generally three years from filing. Keep records six years if you may have omitted more than 25% of gross income, and indefinitely if you never filed.
Federal and Minnesota Differences
Don't assume the two returns match. QBI and bonus depreciation are the clearest gaps for 2026. Check the Minnesota M1M and M1MB instructions every year, because state conformity changes.
Other Minnesota Tax Considerations
Sales Tax and Related Registrations
Selling taxable goods or services creates a sales tax obligation separate from income tax. Register for a Minnesota Tax ID before your first taxable sale. The state rate is 6.875%, plus local taxes.
- Tangible goods and specified services, such as building cleaning and landscape maintenance, are generally taxable.
- General-use clothing and most food are exempt, with exceptions like prepared food and candy.
- Filing frequency follows volume: annual under $100 average monthly tax, quarterly at $100 to $500, monthly above $500.
All returns, including zero returns, are filed through e-Services. Confirm service rules and exemptions with the Department of Revenue.
Business Structure Decisions
A default single-member LLC doesn't remove self-employment tax. Neither does a general partnership.
An S corporation election (Form 2553) can change how profit is taxed, but it adds compliance work:
- Payroll and reasonable compensation for working owners
- Form 1120-S and Minnesota Form M8
The IRS can reclassify distributions as wages if compensation is too low. Weigh the extra compliance cost against your actual profit, with professional input.
When Professional Support Is Useful
Consider a CPA or accountant if you have:
- Multi-state or foreign income (the foreign earned income exclusion doesn't remove self-employment tax)
- Employees or an entity election
- Complex deductions or depreciation
- An IRS notice, since response deadlines can affect appeal rights
- An amended return (Form 1040-X)
- Uncertainty about worker classification

Frequently Asked Questions
Do I pay tax on my small business?
Yes, usually. Depending on profit and what you sell, you may owe federal self-employment tax, federal income tax, Minnesota income tax, and Minnesota sales tax.
What is the Minnesota state income tax rate?
Minnesota uses graduated brackets from 5.35% to 9.85% for 2026. Your rate depends on filing status and taxable income, so check the current Department of Revenue tables.
What is the self-employment tax rate in Minnesota?
It's 15.3% on 92.35% of net profit, and it's federal, not Minnesota-specific. Social Security applies up to a wage ceiling, and Additional Medicare Tax may apply. Minnesota separately taxes income.
Do I have to pay quarterly estimated taxes in Minnesota?
Likely, if you expect to owe $500 or more to Minnesota, or $1,000 or more federally, after withholding and credits. Safe-harbor rules can reduce what you must pay. Check each agency separately.
Which forms do I use to file self-employment tax in Minnesota?
Most filers use Form 1040 with Schedules C, SE, and 1, then Minnesota Form M1. Add Forms 8995, M1M, M1MB, or M1NR where they apply. Partnerships and S corporations use different entity returns.
