Estimated annual sales tax on a median household
A Louisville household at the median income of $67,657 spending roughly a quarter of pre-tax income on taxable retail goods would pay about $1,015 a year in sales tax at 6%. This is an illustration, not a filing figure: the taxable share of spending varies with household composition, and Kentucky exempts or discounts several categories. Kentucky prohibits local sales taxes, so Louisville Metro's rate is the flat state 6% — though Kentucky has been expanding the tax to more services.
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 Louisville-specific measurement.
