Important: Property tax rates vary significantly within District of Columbia by county, city, and school district. The "average effective rate" is the total property tax paid divided by total home value across the state. Your actual rate depends on your property's assessed value, local millage rates, and any applicable exemptions (homestead, senior, veteran, etc.). Contact your county tax assessor for your exact property tax.
