Minnesota's usury law sets a lower ceiling than most states for a written contract — 8% annually — but its Conciliation Court (the state's version of small claims court) allows claims up to $15,000, among the highest limits in the country. Here's what Minnesota freelancers need to know about late fees, the state's interest rate rules, and collecting through Conciliation Court.

Minnesota's Interest Rate Rules
Minnesota's default legal interest rate is 6% per year (Minn. Stat. § 334.01), and the same statute caps a written contract rate at 8% per year for most agreements — lower than the 12-24% range many other states allow. That said, Minnesota carves out real exceptions for business transactions: § 334.011 permits business-purpose contracts under $100,000 to charge a variable commercial rate tied to the 90-day commercial paper discount rate plus 4.5 percentage points, and Minnesota courts have separately recognized that corporations can validly agree to rates well above 8% in ordinary business dealings (see American Druggists Ins. v. Thompson Lumber Co., 349 N.W.2d 569 (Minn. App. 1984), upholding a 12% rate a corporation had accepted on invoices without objection).
In practice, most Minnesota freelancers invoicing other businesses still use the nationwide standard of 1.5% per month (18% annually). If you're concerned about the 8% consumer-facing cap, the safest approach is to confirm your client is a business entity (not an individual consumer) and state your rate clearly in a written contract before work begins.
A Generous Small Claims Limit
Minnesota's Conciliation Court allows claims up to $15,000 — tied for one of the highest limits in the country, well above the $5,000-$10,000 range typical in most states. That means the vast majority of freelance invoice disputes, even sizable ones, can be handled without an attorney or the cost of formal civil court.
Setting Up Enforceable Late Fees in Minnesota
- Confirm you're invoicing a business, not an individual consumer, if you're relying on rates above 8% — the business-purpose exceptions apply most cleanly to B2B transactions.
- Put the rate in writing before work begins. "Invoices unpaid after 30 days accrue interest at 1.5% per month on the outstanding balance" is clear and enforceable.
- Repeat your terms on every invoice so the client sees them without digging through the original agreement.
- Send a written reminder before fees kick in — this creates a clean paper trail if the dispute ever reaches Conciliation Court.
Collecting in Minnesota
Minnesota's Conciliation Court — the state's small claims court — encourages mediation before trial, which resolves many disputes without a formal hearing. No attorney is required, and the process is designed for self-represented filers.
- Minnesota Conciliation Court: up to $15,000 — no attorney required, mediation encouraged
- Minnesota District Court: for claims above $15,000
- Default judgment interest: 6% annually under Minn. Stat. § 334.01, or 10% for judgments over $50,000 under Minn. Stat. § 549.09
