Sales Tax Calculator, Rockville, MD

What shoppers pay in Rockville, MD

With about 67,117 residents, Rockville is a mid-sized Maryland city. Maryland applies a single 6.00% sales tax statewide and allows no county or municipal add-ons. A purchase rings up at the same rate in Rockville as anywhere else in the state, which makes the arithmetic unusually simple.

Census figures (ACS 5-Year 2023) put median household income in Rockville at $122,384, or about $2,354 a week. At the state's typical combined rate, a $500 purchase adds $30.00 in tax, and a $2,000 one adds $120.00. That larger figure works out to roughly 5% of a week's median household income here, which is why timing a big appliance or furniture purchase around a sales tax holiday can be worth the wait.
