Interest is set annually by IFTA, Inc. at 2 percentage points above the underpayment rate established by the IRS. This rate accrues monthly at 1/12 the annual rate.
Washington charges 1% interest on the full amount owed as of the 1st of the following month if the balance due has not been paid. Washington interest is applied to the net balance due on the first of the month following the due date of the filed return.
