Foreign Procurement Excise Tax — Section 5000C

The foreign procurement excise tax under 26 U.S.C. § 5000C (Chapter 50 of the IRC) imposes a 2% excise tax on payments made by the U.S. government to foreign persons — foreign corporations or non-resident alien individuals — for goods acquired or services performed outside the United States. Enacted as part of the Trade Facilitation and Trade Enforcement Act of 2015 and refined by subsequent regulations, the tax is designed to be reciprocal: it applies only when the foreign contractor is a resident or incorporated in a country that subjects U.S. federal contractors to discriminatory taxes not generally imposed on its own domestic contractors. It mirrors the principle that if a foreign country taxes U.S. companies working on U.S. government contracts abroad, the U.S. will impose an equivalent tax on contractors from that country working on U.S. government contracts. For domestic procurement preferences that favor U.S. contractors, see the Buy American Act and trade remedies and tariff law. The Treasury maintains a list of countries whose discriminatory tax practices trigger the § 5000C excise.

Current Law (2026)

Legal Authority

• 26 U.S.C. § 5000C(a) — Imposes a 2% excise tax on every foreign person that receives a specified Federal procurement payment; "specified Federal procurement payment" means any payment made pursuant to a contract with the federal government for goods acquired or services performed outside the United States — but only if the contractor is a resident of or incorporated in a country identified by Treasury as imposing discriminatory taxes on U.S. government contractors
• 26 U.S.C. § 5000C(b) — Withholding: the federal agency making the payment is required to withhold the 2% tax from the contract payment; the agency remits the withheld amount to the IRS; the foreign contractor receives 98% of the contract payment net of tax
• 26 U.S.C. § 5000C(c) — Definitions: "foreign person" means a foreign corporation or a non-resident alien individual; "United States" means the 50 states and DC; "specified Federal procurement payment" excludes payments for work performed within the United States
• 26 U.S.C. § 5000C(d) — Credits: the foreign person may claim a credit for the withheld excise tax against the U.S. income tax liability attributable to the same income (if the foreign person is otherwise subject to U.S. tax on the procurement income)
• Treasury Regulations (26 CFR § 1.5000C) — The implementing regulations specify: (1) the list of discriminatory countries subject to the excise, (2) procedures for agencies to withhold and remit the tax, (3) the definition of "outside the United States," and (4) the exemption certificate procedures for foreign contractors from non-discriminatory countries

How It Works

Section 5000C is a trade reciprocity tool: if a foreign country taxes U.S. companies on earnings from that country's government contracts but doesn't impose equivalent taxes on its own domestic contractors, that's discriminatory treatment. The U.S. responds by imposing a 2% excise tax on contractors from that country when they receive U.S. government payments for work performed outside the United States. The Treasury Department, in consultation with the U.S. Trade Representative, maintains the list of discriminatory countries — countries are added when Treasury determines they maintain discriminatory tax regimes against U.S. contractors and removed when they eliminate such discrimination. As of 2026, the list covers countries imposing withholding taxes, turnover taxes, or other levies specifically on U.S. federal contractors that don't apply to domestic contractors in those countries.

Federal contracting agencies withhold 2% from each progress or milestone payment to contractors from listed countries. Sophisticated foreign contractors often price this cost into their bids — the agency pays 100% of the contract price but the contractor nets only 98%. Foreign contractors from non-listed countries can obtain an exemption by filing IRS Form W-14 (Certificate of Foreign Contracting Party Receiving Federal Procurement Payments) certifying they are not resident in or incorporated under the laws of a discriminatory country; incorrect exemption claims trigger the 2% tax plus interest and penalties. If a foreign contractor paying the § 5000C excise also has U.S.-source income subject to U.S. income tax — for example, if the procurement activity creates a U.S. trade or business — the excise paid can be credited against the resulting income tax liability; tax treaty provisions may provide additional relief, but treaty interaction with § 5000C requires case-by-case analysis.

How It Affects You

If you're a foreign contractor or a U.S. subsidiary of a foreign company bidding on U.S. government contracts: Before bidding on any federal contract that involves work performed outside the United States, determine whether your country of incorporation or residence appears on Treasury's § 5000C discriminatory country list (published by the IRS at irs.gov/businesses/corporations/section-5000c-withholding). If it does, the contracting agency is required to withhold 2% from each payment you receive under the contract. This withholding is not optional and not negotiable — it is a tax withheld at source by the government agency itself. To avoid the withholding, you must be from a non-discriminatory country and submit IRS Form W-14 (Certificate of Foreign Contracting Party Receiving Federal Procurement Payments) to the contracting officer before your first payment. Form W-14 certifies your country of residence or incorporation and serves as your exemption certificate. If you're a U.S.-incorporated subsidiary of a foreign parent: U.S. subsidiaries organized under U.S. law are generally not "foreign persons" for § 5000C purposes — the tax applies to the foreign entity directly contracting with the U.S. government, not to a domestic subsidiary that is itself the contractor. Structure your contracting arrangements accordingly, and confirm this analysis with your tax counsel before assuming exemption applies. Credits are available against U.S. income tax if the § 5000C excise creates double taxation on income from a U.S. trade or business.

If you're a U.S. government contracting officer, DCAA auditor, or procurement compliance professional: Section 5000C withholding is a mandatory compliance obligation for contracts involving foreign persons performing work outside the United States — it is not at the contracting officer's discretion. Your agency must: (1) identify contracts that may involve foreign persons performing work abroad during the solicitation stage; (2) require Form W-14 from any contractor claiming an exemption; (3) withhold 2% from payments to contractors from discriminatory countries who have not submitted a valid W-14; and (4) remit the withheld amounts to the IRS. The FAR (Federal Acquisition Regulation) at 48 CFR Part 29 contains implementing guidance; failure to withhold can create agency liability. Include § 5000C representations and withholding clauses in solicitations for overseas contracts. The IRS § 5000C withholding guidance at irs.gov and DCAA Contract Audit Manual provide compliance frameworks; the Office of Federal Financial Management (OFFM) at OMB has issued coordination guidance for multi-agency contracts.

If you're a trade attorney, policy analyst, or multinational corporation with government contracting exposure: Section 5000C operates as a tax-code-based reciprocity mechanism — the U.S. imposes a 2% excise on contractors from countries that discriminate against U.S. government contractors in their own procurement markets, creating direct economic pressure to reform those domestic policies. The discriminatory country list is Treasury's lever: countries that remove discriminatory procurement policies get removed from the list, and their contractors regain the ability to compete for U.S. government work abroad without the 2% cost disadvantage. This mechanism complements the WTO Agreement on Government Procurement (GPA), which prohibits discriminatory government procurement among signatories, but operates independently through domestic tax law. For corporations with operations in multiple jurisdictions bidding on U.S. government overseas work, understanding which entities in your corporate family qualify as "foreign persons" and whether their countries of incorporation are on the discriminatory list is essential bid pricing and compliance work. The U.S. Trade Representative (ustr.gov) and Commerce Department BIS (bis.doc.gov) publish guidance on foreign procurement discrimination issues that inform the Treasury country list; changes to the list follow Treasury regulatory processes with public notice.

Pending Legislation

No major pending legislation as of April 2026. Section 5000C was implemented in 2015 and Treasury continues to refine the country list. Trade negotiations (bilateral and multilateral) periodically address government procurement discrimination issues that affect which countries appear on the list.

Recent Developments

• 2025 Trump trade executive orders: The administration's sweeping use of tariffs and trade remedies under Section 232 and IEEPA in 2025 intensified scrutiny of foreign contractor access to U.S. government contracts broadly. While § 5000C's reciprocal excise operates independently of tariff law, contracting officers began applying heightened "country of origin" analysis simultaneously, creating a more complex compliance environment for foreign defense and IT contractors.
• Buy American rule tightening (2022-2025): OMB's Buy American Act implementing rule revisions (effective January 2022) increased domestic content thresholds — 55% domestic content for manufactured goods, rising to 65% by 2024 — creating pressure on foreign contractors to restructure supply chains. The § 5000C excise applies separately but in parallel: a foreign contractor that meets the new Buy American thresholds for the domestic content of goods may still owe § 5000C excise if the foreign contractor is a "foreign person" from a discriminatory country.
• USTR procurement negotiations: The U.S. Trade Representative's 2025 annual report on trade barriers identified government procurement discrimination against U.S. contractors in several markets including certain Middle Eastern and Southeast Asian countries. Countries named in USTR procurement reports are candidates for Treasury's § 5000C discriminatory country list if they impose taxes on U.S. federal contractors without imposing equivalent taxes on domestic contractors.
• Treasury regulatory guidance: IRS and Treasury have maintained the Form W-14 exemption certificate framework but have not revised § 5000C implementing regulations significantly since 2016. Practitioners note that Treasury's discriminatory country list has expanded incrementally but is not publicly posted in a centralized, easily searchable format — a practical compliance gap for contracting officers and foreign contractors alike.
