Maine keeps sales tax simple: a flat 5.5% statewide rate with no local sales taxes at all. A few categories carry special rates — prepared food and lodging at 8% and short-term auto rentals at 10% — while grocery staples and prescription medicine are fully exempt. This calculator applies the correct Maine rate for the item type you choose and can add tax to a price or remove tax from a total.
How it works
Maine’s general rule is straightforward because there is only one base rate to apply:
- Pick the rate by item type. General goods are taxed at
5.5%; prepared food and lodging at8%; short-term auto rentals at10%; groceries and prescription drugs are exempt (0%). - Add mode.
tax = price x rate, andtotal = price + tax. - Remove mode. Given a tax-inclusive total, the pre-tax price is
total / (1 + rate), and the tax istotal - pre-tax.
Because there are no county or city add-ons, the same rate applies anywhere in Maine.
Tips and example
A $200 restaurant bill is “prepared food,” so it is taxed at 8%: $200 x 0.08 = $16 tax, for a $216 total. The same $200 spent on a TV (general goods) is taxed at 5.5%: $11 tax, $211 total. A $200 grocery run of unprepared food is exempt — $0 tax.
To split out the tax already baked into a receipt, use remove mode: a $216 prepared-food total divided by 1.08 gives the $200 pre-tax price and $16 of tax. Always confirm whether a specific item qualifies as exempt or prepared at Maine Revenue Services, since classification edge cases exist.
