(a) Any past-due, legally enforceable debt of at least $25, or such other minimum amount as determined by the Secretary of the Treasury, shall be submitted to FMS for collection by tax refund offset.

(b) FMS will compare tax refund payment records, as certified by the IRS, with records of debts submitted by the Department under this part. A match will occur when the taxpayer identification number and name of a payment certification record are the same as the taxpayer identifying number and name control of a debtor record. When a match occurs and all other requirements for tax refund offset have been met, FMS will reduce the amount of any tax refund payment payable to a debtor by the amount of any past-due legally enforceable debt. Any amounts not offset will be paid to the payee(s) listed in the payment certification record.
