Prompt Payment — Overview of Requirements
Interest Rate

The interest rate the state pays on a late payment due to a vendor under the state’s prompt payment law is calculated on an annual basis. The interest calculation is one percentage point higher than the prime rate published in the Wall Street Journal on the first business day of July.

The prime rate on July 3, 2017, was 4.25 percent. For fiscal 2018, the rate of 5.25 percent must be used on any payment that becomes late between Sept. 1, 2017, and Aug. 31, 2018.

State agencies must apply this rate to late payments made from all funds, including local funds. You can view the interest rate in the Uniform Statewide Accounting System (USAS) on the Late Payment Interest Rate (D98) Profile.

Note: Even if a payment is late during two different fiscal years, only one rate will be used in the calculation of interest. The rate used is always based on the fiscal year in which the payment becomes late.
