- The daily interest rate is derived by dividing the annual interest rate by the number of days in a given year (365 or, for a leap year, 366). The OPM back pay interest program (released in September 1999) rounds daily interest rates to the 9th decimal place.
- The Office of Personnel Management (OPM) provides these interest rates as a convenience for Federal personnel management specialists. Every attempt has been made to provide accurate data; however, the official rates are established by the Internal Revenue Service, Department of the Treasury.
- Official rates may be obtained by calling the IRS Federal Tax Information Line (1-800-TAX-1040) and requesting the interest rate paid on tax overpayments determined under section 6621 of the Internal Revenue Code.
