About Maryland property tax

Maryland property tax is billed and collected county by county, so the collector — not the state — issues the bill. Every county must offer the semiannual Sept 30 / Dec 31 schedule for owner-occupied homes and small business property, but tax-sale dates and interest rates are set locally, so collection calendars differ.
