Prompt Payment — Overview of Requirements
Interest Liability, Computation and Payment

A payment by a state agency to a vendor for goods or services is overdue by the 31st day after the later of:

  • The date the agency receives the goods and/or services in accordance with the contract, and
  • The date the agency receives a correct invoice for the goods and/or services.

A state agency is liable for any interest that accrues on an overdue payment under the prompt payment law. The interest must be paid at the same time the principal is paid. Interest starts accruing on the date the payment becomes overdue.

Please see Interest Rate for the current interest rate for late payments.

The interest rate the state pays on a late payment 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 Comptroller’s office may:

  • Require a state agency to submit any information necessary to determine compliance with the prompt payment law, or
  • Require an agency to change its accounting systems or procedures in accordance with the law.
