Rate Update Information
To make it easier for you to keep up with city and county rate changes and city boundary changes, Oklahoma statutes were amended to require that these changes could only occur on the first day of a calendar quarter. In addition, the Tax Commission is required to provide 60 days notice to retailers prior to any change. To fulfill these requirements, the Tax Commission will be making the rates for the upcoming quarter available at least 60 days before the beginning of that quarter. The Commission will also separately post all rate and boundary changes so retailers can easily identify changes that might impact their sales. The address and 9-digit ZIP Code information included in the data system will be routinely updated. You will not need to check for these updates unless you were unable to find a specific address and were required to use a default rate.
