(a) Debt collection. The Debt Collection Improvement Act of 1996 requires each contractor doing business with GSA to furnish its Tax Identification Number (TIN). The Government is required to include with each certified voucher prepared and submitted to a disbursing official, the TIN of the contractor receiving payment under the voucher. The TIN may be used by the Office of Financial Policy and Operations to collect and report on any delinquent amounts arising out of the contractor's relationship with the Government.

(b) Information reporting to the IRS. The TIN is also required for Office of Financial Policy and Operations reporting of certain contract information (see FAR 4.903) and payment information (see GSAM 504.904) to the IRS.
