Rate Locator System: Liability Protection

The tax rate data system is provided by the Oklahoma Tax Commission to assist you in charging your customer the correct state and local tax rate. The data system assigns a combined state and local tax rate for each ZIP+4 area code. You may rely on this data system to determine the proper sales or use tax rate at the location in which delivery to the purchaser occurred. If you rely on this data system, you will be held harmless for any erroneous data provided by the Tax Commission on tax rates, boundaries, or taxing jurisdiction assignments.
