FAR and DFARS › FAR Part 52: Solicitation Provisions and Contract Clauses › Subpart 52.2

FAR 52.204-3 Taxpayer identification.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This provision requires offerors to provide their Taxpayer Identification Number (TIN) and related information when responding to a solicitation. It matters because failure to furnish the information may result in a 31 percent reduction of payments under the contract if the contract is subject to payment reporting requirements. The TIN may also be used by the Government to collect delinquent amounts and verify the TIN against IRS records.

Applies to: All offerors responding to a solicitation that includes this provision.

What it requires

  • Submit the information required in paragraphs (d) through (f) of this provision.
  • Provide the Taxpayer Identification Number (TIN) or indicate that a TIN has been applied for or is not required.
  • Indicate the type of organization.
  • Indicate whether the offeror is owned or controlled by a common parent and, if so, provide the name and TIN of the common parent.

The text

As prescribed in 4.905, insert the following provision:

Taxpayer Identification (OCT 1998)

(a) Definitions.

Common parent, as used in this provision, means that corporate entity that owns or controls an affiliated group of corporations that files its Federal income tax returns on a consolidated basis, and of which the offeror is a member.

Taxpayer Identification Number (TIN), as used in this provision, means the number required by the Internal Revenue Service (IRS) to be used by the offeror in reporting income tax and other returns. The TIN may be either a Social Security Number or an Employer Identification Number.

(b) All offerors must submit the information required in paragraphs (d) through (f) of this provision to comply with debt collection requirements of 31 U.S.C. 7701(c) and 3325(d), reporting requirements of 26 U.S.C. 6041, 6041A, and 6050M, and implementing regulations issued by the IRS. If the resulting contract is subject to the payment reporting requirements described in Federal Acquisition Regulation (FAR) 4.904, the failure or refusal by the offeror to furnish the information may result in a 31 percent reduction of payments otherwise due under the contract.

(c) The TIN may be used by the Government to collect and report on any delinquent amounts arising out of the offeror's relationship with the Government (31 U.S.C. 7701(c)(3)). If the resulting contract is subject to the payment reporting requirements described in FAR 4.904, the TIN provided hereunder may be matched with IRS records to verify the accuracy of the offeror's TIN.
