Guides Minnesota businesses through a complete sales and use tax compliance engagement: nexus determination, exemption review, return preparation on Form ST-1, and filing via MNDOR e-Services. Covers the 6.875% state rate, local option taxes, SST membership, and Minnesota-specific exemptions including all clothing, SaaS, and capital equipment.
Determine whether the business has sales tax nexus in Minnesota — physical presence (office, employees, inventory, delivery vehicles) or economic nexus ($100,000 in sales OR 200 separate transactions into Minnesota in the current or prior calendar year). Confirm whether the business is already registered with MNDOR or needs to complete a new registration via e-Services before collecting tax.
Classify all sales transactions for the filing period by taxability. Apply Minnesota-specific rules: all clothing and footwear is exempt (no minimum threshold); grocery food is exempt but prepared food is taxable; SaaS is not taxable; canned/downloaded software and specified digital products are taxable at 6.875%; professional services are not taxable; manufacturing equipment qualifies for the capital equipment exemption and refund program. Document each product/service line with its taxability determination.
Determine the applicable combined rate for each taxable sale using Minnesota's destination-based (SST) sourcing rules. The state rate is 6.875%; many Minnesota cities and counties impose local option sales taxes ranging from 0.25% to approximately 2%, bringing combined rates up to ~8.875% in some jurisdictions (e.g., Minneapolis, St. Paul, Duluth). Apply the correct rate to each transaction based on the ship-to address of the buyer.
Prepare the Minnesota Sales and Use Tax return (Form ST-1 or the e-Services equivalent) for the filing period. Report gross sales, deduct exempt sales by category (clothing, food, resale, etc.), compute net taxable sales, apply the state rate and local rates, add any self-assessed use tax, subtract any credits or prepayments, and arrive at tax due. Verify the capital equipment refund claim (Form ST11 / ST11A) if applicable.
Submit the completed ST-1 return electronically via MNDOR e-Services and remit payment by the due date. Monthly filers: 20th of the following month. Quarterly filers: 20th of the month following the quarter-end. Annual filers: February 5 of the following year. Confirm the electronic submission acknowledgment and retain the confirmation number. Flag any late-filing penalty exposure (5% of tax due) or interest accruals if filing is past due.
