Estimated annual sales tax on a median household
A Portland household at the median income of $74,129 spending roughly a quarter of pre-tax income on taxable retail goods would pay about $1,019 a year in sales tax at 5.5%. This is an illustration, not a filing figure: the taxable share of spending varies with household composition, and Maine exempts or discounts several categories. Maine allows no local sales tax, but prepared food is taxed at 8% and short-term lodging at 9%, which matters in a tourist-heavy Portland.
Method: median household income × 25% taxable share × combined rate. The 25% share is a rough national benchmark from the BLS Consumer Expenditure Survey, not a Portland-specific measurement.
