Maine Reverse Sales Tax Calculator.

Maine has a uniform state sales tax rate of 5.5% with no local sales taxes. Like Connecticut, Indiana, and Kentucky, Maine's system is simple — the rate is the same in Portland, Bangor, Augusta, and every other Maine municipality. There are no county taxes, no city taxes, and no special district sales taxes on top of the state rate.

Maine does apply different rates to specific categories. Lodging (hotel, motel, and other accommodations) is taxed at a higher 9% rate in Maine. Restaurant meals and prepared food are taxed at 8% rather than the standard 5.5%. Auto rentals are taxed at 10%. These elevated rates on tourism-related services reflect Maine's economy, which has a significant tourism component.

Maine's primary sales tax exemptions include: food for home consumption (unprepared groceries), prescription drugs, most over-the-counter medications, certain agricultural inputs, heating fuels for residential use, and sales to qualifying nonprofit organizations. Maine has a relatively broad exemption for purchases by 501(c)(3) organizations and government entities.

The Maine Revenue Services (MRS) administers the state sales tax. Filing frequency depends on monthly liability: monthly for those with over $600 in monthly liability, quarterly for smaller filers, and annual for very small sellers. Maine participates in the SST agreement for multi-state compliance.

Maine's economic nexus threshold is $100,000 in annual Maine sales. Maine does not use a transaction count threshold. Maine has adopted marketplace facilitator laws requiring platforms like Amazon to collect and remit Maine sales tax.
