FAR 4.9—Subpart 4.9

Scope of subpart.

FAR 4.900 is the scope statement for Subpart 4.9 and explains that this subpart is about two specific information-collection functions in federal contracting: obtaining Taxpayer Identification Number (TIN) information that can be used for debt collection, and obtaining contract and payment information that must be sent to the payment office for Internal Revenue Service (IRS) reporting. In practice, this means the subpart is not a general records-management rule; it is a targeted policy framework for collecting and routing taxpayer and payment data needed to support government debt collection and tax reporting obligations. The section matters because agencies must have the right identifying and payment information to comply with fiscal controls, support collection of debts owed to the Government, and ensure accurate IRS reporting. Contractors should understand that this subpart signals that certain tax-related data may be requested and used for official government purposes, and that providing accurate information is important to avoid payment delays, reporting errors, or collection problems. Contracting personnel and payment offices must coordinate so the information collected is complete, timely, and suitable for the intended downstream use.

Definition.

FAR 4.901 provides a single, specialized definition used in this subpart: "common parent." It explains which corporate entity counts as the parent for purposes of the rule set by tying the term to an affiliated group of corporations that files Federal income tax returns on a consolidated basis, and by requiring that the offeror be a member of that group. In practice, this definition matters because it identifies the correct corporate parent when the subpart requires reporting, representation, or other actions based on corporate affiliation rather than on a standalone legal entity. The definition is tax-structure-specific, so it focuses on consolidated Federal income tax filing status rather than broader concepts like ownership in the abstract or general corporate family relationships. For contractors, the key significance is determining whether the offeror belongs to a consolidated group and, if so, which entity is the controlling parent for compliance purposes. For contracting personnel, the definition helps ensure that any requirements in the subpart are applied to the right corporate entity and not to an unrelated affiliate or subsidiary.

General.

FAR 4.902 explains why the Taxpayer Identification Number (TIN) matters in federal contracting and payment processing. It covers two related topics: debt collection and IRS information reporting. First, it states that contractors doing business with a Government agency must furnish their TIN, and that the Government uses the TIN on certified vouchers submitted for payment so it can identify the contractor being paid. Second, it explains that the TIN is also needed so the Government can report certain contract information and payment information to the IRS under FAR 4.903 and 4.904. In practical terms, this section ties contractor identification to both payment administration and tax reporting, making accurate TIN collection and use essential for timely payment, compliance, and government-wide financial accountability.

Reporting contract information to the IRS.

FAR 4.903 explains when federal executive agencies must report contract information to the IRS and how that reporting is done. It implements the tax-reporting requirement in 26 U.S.C. 6050M and the related IRS regulations, and it applies to certain contract actions and modifications that meet specific dollar thresholds and effective dates. The section identifies two reporting categories: modifications to contracts awarded before January 1, 1989 that increase the contract amount by $50,000 or more and are entered into on or after April 1, 1990, and certain contracts and modifications entered into on or after January 1, 1989 that exceed $25,000. It also specifies exactly what information must be reported: the contractor’s name, address, and TIN; the common parent’s name and TIN if applicable; the date of the contract action; the amount obligated; and the estimated completion date. In practice, this means contracting offices must capture accurate taxpayer and contract data at the time of award or modification and ensure it is transmitted through the Federal Procurement Data System (FPDS) in accordance with subpart 4.6 and agency instructions. The rule exists to support IRS information reporting and tax compliance, so accuracy, timeliness, and correct identification of reportable actions are critical.

Reporting payment information to the IRS.

FAR 4.904 explains how the government handles IRS information reporting for contractor payments. It ties together the tax-law requirements in 26 U.S.C. 6041 and 6041A, the implementing rules in 26 CFR, and the contractor taxpayer identification number (TIN) requirement in 26 U.S.C. 6109. In practical terms, this section tells agencies that certain payments to contractors may have to be reported to the IRS on Form 1099, and it identifies the payment office as the party responsible for sending those reports. It also makes clear that contractors must furnish a TIN when a Form 1099 is required, which supports accurate tax reporting and IRS matching. The section matters because it affects payment processing, vendor setup, tax compliance, and the government’s ability to meet statutory information-reporting obligations.

Solicitation provision.

FAR 4.905 tells contracting officers when they must include the solicitation provision at 52.204-3, Taxpayer Identification, in a solicitation. The section is narrow but important: it applies only when the solicitation does not already include the System for Award Management provision at 52.204-7 and when the acquisition is not being conducted under the procedures of FAR part 12, which covers commercial products and commercial services. In practice, this rule helps ensure the Government collects the contractor’s taxpayer identification information in solicitations that are outside the SAM-based and part 12 frameworks. It is a drafting and compliance requirement for the solicitation stage, not a post-award performance rule. Contracting officers must check both conditions before issuing the solicitation, because the provision is required only when both exceptions apply.
