IFTA Interest Rates
Effective July 1, 2013, the IFTA Articles of Agreement require that the annual interest rate for IFTA be set 2 percentage points above the IRS underpayment rate. The adjustment will occur on January 1 of each year. IFTA interest accrues monthly at the rate of 1/12 of the annual rate. See the tables below for the applicable rates. These rates are set by IFTA, Inc. For more information, see the IFTA website at iftach.org.
