The sales tax rate in Forest Lake, MN is 8.375% on most taxable purchases. Forest Lake does not add a city sales tax of its own; the full local portion comes from Washington County and two Twin Cities metro-area taxes layered on top of the Minnesota state rate.
What Makes Up the 8.375% Rate
Four separate taxes are collected together at the register:
- Minnesota state sales tax: 6.875% (a 6.5% base plus a constitutionally required 0.375% addition for outdoor and environmental spending).1Minnesota Office of the Revisor of Statutes. Minnesota Statutes 297A.62 – Sales Tax Imposed; Rates
- Washington County transit tax: 0.50%, split evenly between road and bridge projects and transit.2Washington County, MN. Local Option Sales Tax
- Metro area transportation tax: 0.75% for regional transit infrastructure.3Minnesota Department of Revenue. Metro Area Transportation Sales and Use Tax
- Metro area housing tax: 0.25% for affordable housing in the metro region.4Minnesota Department of Revenue. Local Sales and Use Tax Rate Guide 2026 Q2
Retailers collect the full combined amount and send it to the Minnesota Department of Revenue, which then distributes the local shares.
What’s Exempt From the Rate
Groceries
Food and food ingredients purchased for home consumption are exempt. That covers produce, meat, dairy, bread, and canned goods. It does not cover candy, soft drinks, dietary supplements, prepared food, or alcohol.5Minnesota Office of the Revisor of Statutes. Minnesota Code 297A.67 – General Exemptions
Prepared food is where confusion usually starts. If the seller heats or mixes the food, or hands you utensils with it, the full 8.375% applies. A rotisserie chicken from the hot case is taxable; raw chicken from the cooler is not. Restaurant meals, food truck orders, and catering are all taxable.
Clothing
Most clothing is exempt, but several categories are not: fur clothing, sports and recreational gear (cleats, ski boots, wetsuits), protective equipment (hard hats, safety glasses), and accessories such as jewelry, handbags, watches, and sunglasses. Sewing supplies are taxable even when they’ll become part of clothing.5Minnesota Office of the Revisor of Statutes. Minnesota Code 297A.67 – General Exemptions
Medications and Medical Devices
Prescription and over-the-counter drugs are exempt, as are durable medical equipment for home use, prosthetic devices, mobility-enhancing equipment, and kidney dialysis equipment.5Minnesota Office of the Revisor of Statutes. Minnesota Code 297A.67 – General Exemptions
Vehicles Are Taxed Differently
Buying a car does not follow the 8.375% rate. The state’s 6.875% applies to vehicle purchases, but the local sales taxes do not. In their place, a flat $20 local vehicle excise tax applies where imposed. A Forest Lake resident buying a $30,000 vehicle pays $2,062.50 in state sales tax plus the $20 excise tax.6Minnesota Department of Revenue. Motor Vehicle Sales
Online Orders Shipped to Forest Lake
Minnesota uses destination-based sourcing. The tax rate is set by where you receive the product, not where the seller sits. Something ordered online and shipped to a Forest Lake address is taxed at 8.375% no matter where the seller operates. If you pick the item up at a store instead, the rate at that store’s location applies.7Minnesota Office of the Revisor of Statutes. Minnesota Statutes 297A.668 – Sourcing of Sale; Situs in This State
When the Seller Doesn’t Charge Tax
If you buy a taxable item and no Minnesota sales tax is charged, you owe use tax at the same 8.375% rate. This comes up with small out-of-state vendors and private-party sales. You can pay it by filing Form UT1 with the Department of Revenue or by reporting it on your Minnesota income tax return.8Minnesota Department of Revenue. Sales and Use Tax
