Oklahoma Municipal Finance Glossary

Plain-English definitions for the terms used across MuniRevenue's Oklahoma city and county revenue data.

Sales tax: A tax on the retail sale of goods and many services. In Oklahoma, the state plus the local city and county each levy a rate; the combined rate varies by jurisdiction.
Use tax: A complementary tax on taxable goods bought out-of-state or online for use in Oklahoma when sales tax was not collected at purchase. Levied at the same local rates as sales tax.
Lodging tax: A separate occupancy tax some Oklahoma cities levy on short-term hotel, motel, and rental stays, often dedicated to tourism or convention purposes.
Apportionment: The Oklahoma Tax Commission's monthly distribution of collected local sales and use tax back to the city or county that levied it.
Oklahoma Tax Commission (OTC): The state agency that collects and apportions Oklahoma sales, use, and other taxes, and publishes the underlying distribution data via OkTAP.
OkTAP: The Oklahoma Taxpayer Access Point (oktap.tax.ok.gov), the OTC system through which monthly tax distribution reports are published.
COPO: City Or County Of — the identifier MuniRevenue uses to key each Oklahoma jurisdiction's records.
NAICS: North American Industry Classification System — the code set used to break a jurisdiction's revenue down by industry.
Returned: The dollar amount of local tax apportioned (returned) to a jurisdiction for a given month — the core figure MuniRevenue tracks.
Trailing twelve months (TTM): The sum of the most recent twelve months of revenue, used to compare jurisdictions on a full-year basis that smooths out seasonality.
Year-over-year (YoY): The percentage change versus the same month one year earlier, the standard way to gauge whether revenue is growing or shrinking.
Month-over-month (MoM): The change from the immediately preceding month; useful for spotting abrupt shifts but noisier than year-over-year.
Seasonality: The recurring within-year pattern in a jurisdiction's revenue (for example, holiday-quarter retail strength) that MuniRevenue measures with seasonal indices.
Anomaly: A statistically unusual revenue movement — a spike, drop, or trend break — flagged by MuniRevenue for investigation.
Missed filing: A NAICS category whose current activity falls materially below its recent run-rate, signaling a likely-missing tax filing.
Forecast: A projection of a jurisdiction's future revenue, with a confidence band, produced from several statistical models and economic drivers.
