Who sends the property tax bill in Loudoun County, and how do you pay it?
The bill comes from the Loudoun County Treasurer's Office. The value it is based on is set by a separate office, the Loudoun County Commissioner of the Revenue, which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
The Commissioner of the Revenue values every property each year as of January 1, and assessment notices go out in February; the Treasurer sends the bills and collects. The county also bills and collects the town real estate tax for all seven incorporated towns (Hamilton, Hillsboro, Leesburg, Lovettsville, Middleburg, Purcellville and Round Hill), so the town tax appears as a separate line on the same county bill and is paid with one payment to the county. A property in a special tax district may get an additional bill, and some mortgage companies do not pay it. Online card payments run through the Paymentus portal: eChecks are free, while credit cards, debit cards and digital wallets carry a service fee.
