Government agencies are exempt from Form W-9 requirements because the two purposes of the form — collecting a taxpayer identification number for backup withholding and for 1099 reporting — don’t apply to them. You don’t have to issue a 1099 to a federal, state, or local agency, and the agency has no obligation to hand you a W-9. Many will still provide one with an exemption code filled in, or a substitute document that gives you the same information for your vendor file.
Why the Exemption Exists
Under 26 U.S.C. § 115, income a state or political subdivision earns through its governmental functions is excluded from gross income.1Office of the Law Revision Counsel. Title 26 Internal Revenue Code – Income of States, Municipalities, Etc. Federal agencies share exempt status as part of the sovereign itself. These entities don’t file income tax returns and don’t sit in the 1099 reporting system the way a private contractor does.
Form W-9 exists so a payer can determine whether backup withholding applies and prepare year-end information returns.2Internal Revenue Service. Instructions for the Requester of Form W-9 (Rev. March 2024) Backup withholding under 26 U.S.C. § 3406 runs at 24% when a payee fails to furnish a valid TIN. Section 3406(g)(1) exempts organizations and governmental units described in 26 U.S.C. § 6049(b)(4): the United States, states, the District of Columbia, U.S. possessions, their political subdivisions, and any wholly owned agencies of those entities.3Office of the Law Revision Counsel. 26 USC 3406 – Backup Withholding With both underlying obligations off the table, the form has nothing to do.
When an Agency Will Still Provide a W-9
Plenty of agencies will complete a W-9 if you ask. Line 4 of the form carries exempt payee codes for exactly this situation. Code 2 covers “The United States or any of its agencies or instrumentalities,” and code 3 covers “A state, the District of Columbia, a U.S. commonwealth or territory, or any of their political subdivisions or instrumentalities.”4Internal Revenue Service. Form W-9 (Rev. March 2024) – Line 4 Exemptions A W-9 returned with one of these codes tells you the entity’s name and EIN while confirming that nothing needs to be withheld and no 1099 issued.
What form the documentation takes varies by agency. Larger federal agencies typically publish a standardized substitute W-9 or exemption letter through their finance or procurement offices. A smaller municipal office may just print its EIN on official letterhead. Any of these approaches works for your records.
What to Keep in Your Vendor File
The IRS requester instructions let you rely on a payee’s claim of exemption unless you have actual knowledge the code or classification is invalid.5Internal Revenue Service. Instructions for the Requester of Form W-9 (03/2024) In practice, any of the following gives you what you need:
- A substitute W-9 or exemption letter from the agency, usually posted on its procurement or finance page.
- Official letterhead, a signed contract, or a purchase order that shows the agency’s legal name and EIN.
- SAM.gov registration data for federal agencies and many state and local entities registered in the System for Award Management.
Once you have the name and EIN, flag the vendor as exempt in your accounting software so it doesn’t generate a 1099 or apply backup withholding at year-end. Store whatever exemption documentation you collected in a central place you can retrieve if an auditor asks why no 1099 went out.
No 1099 Required, Whatever the Amount
Treasury regulations explicitly exclude payments to government entities from information reporting. Under 26 CFR § 1.6041-3(p), no return of information is required for payments made to the United States, any state, the District of Columbia, U.S. possessions, or any political subdivision of those entities, along with their wholly owned agencies.6GovInfo. 26 CFR 1.6041-3 – Payments for Which No Return of Information Is Required That covers Form 1099-NEC, 1099-MISC, and other information returns for fees, permits, utility payments, or services purchased from a government body.
The exemption applies regardless of the dollar amount. Even if a single agency receives hundreds of thousands of dollars from you in a year, no 1099 is triggered. There is no threshold to track.
Record Retention
The IRS requires payers to keep copies of filed information returns, or the ability to reconstruct the data, for at least three years from the return’s due date.7Internal Revenue Service. General Instructions for Certain Information Returns (2025) The same logic applies to the documentation that explains why you didn’t file a 1099 for a government vendor. Exemption letters, substitute W-9s, and correspondence confirming the entity’s status give an auditor a clean trail. Many accountants recommend holding these records for four years as a buffer if backup withholding questions could arise later.
Where Misclassification Gets Expensive
The exemption only helps when the payee is actually a government entity. Flag a private vendor as government-exempt and you skip the W-9, skip backup withholding that may be required, and miss the 1099 deadline. The IRS treats each missing or incorrect information return as a separate violation, and 2026 penalties climb quickly:
- Filed up to 30 days late: $60 per form.
- Filed 31 days late through August 1: $130 per form.
- Filed after August 1 or not filed at all: $340 per form.
- Intentional disregard: $680 per form, with no cap on the total.8Internal Revenue Service. Information Return Penalties
Separately, if you should have applied 24% backup withholding and didn’t, the payer, not the payee, is on the hook for the tax that should have been withheld.9Internal Revenue Service. Notice 25-03 – Transitional Relief Under Sections 3403, 3406, 6721, 6722, 6651, and 6656
Quasi-governmental payees are where classification errors most often start. A public university or county hospital is typically a political subdivision and qualifies for the exemption. A private contractor working on a government project does not. When you’re unsure, request a W-9 and let the entity self-certify on line 4. If it’s genuinely exempt, it will know which code applies.
Foreign Governments Use a Different Form
If the payee is a foreign government, a foreign central bank, or an international organization, the W-9 does not apply at all: W-9 is only for U.S. persons. These entities provide Form W-8EXP instead to establish identity and claim exemption from U.S. withholding tax.10Internal Revenue Service. Instructions for Form W-8EXP Under 26 U.S.C. § 892, foreign governments are exempt from U.S. tax on certain investment income, but that exemption falls away for commercial activity.11Office of the Law Revision Counsel. 26 U.S. Code 892 – Income of Foreign Governments and of International Organizations The information-reporting exemption in 26 CFR § 1.6041-3(p)(5) and (p)(6) extends to foreign governments, their political subdivisions, and international organizations, so no 1099 is required for payments that fall within the § 892 exemption.6GovInfo. 26 CFR 1.6041-3 – Payments for Which No Return of Information Is Required
