The invoice is for your property’s assessment or tax as a part of the Downtown OKC Business Improvement District (BID). Properties within this designated area pay a special assessment for the maintenance, development, and promotion of downtown and their specific district. Assessments are billed by and collected by the City of Oklahoma City.

BID assessments are mainly driven by the net assessed value of the property. Additional factors include the property’s frontage (linear feet that faces the street), street-level services (such as landscaping and maintenance), district classification (Automobile Alley, Bricktown, Midtown), and access to amenities (Canal or Underground).

A property’s BID assessment can vary year to year due to but not limited to the following variables: change in net assessed value of the property, change in level of street-level services, change in level of maintenance, development, and marketing services.

Assessments are invoiced annually on an October 1- September 30 fiscal year.

Payments can be made in person at the City of OKC Treasury Department (420 West Main) or mail your payment directly to the City of OKC to the address shown on your invoice. Do not send payments to the Water Utilities lockbox. The proper mailing address is 420 W. Main St, Suite 120, Box 3, OKC, 73102. Unfortunately, the City of OKC does not have the capability to collect payment over the phone or online. Due to COVID, access may be limited to City buildings, so we recommend mailing in payments.
