Treasury updates list of countries tied to international boycott rules

The U.S. Department of the Treasury published its current list of countries that require or may require participation in an international boycott under §999 of the Internal Revenue Code.

The list matters because U.S. taxpayers involved in business with these countries may trigger U.S. anti-boycott reporting requirements and potential tax consequences.

The notice does not change the law. It simply updates the list Treasury uses for compliance monitoring.

The Law in Play

The governing statute is §999 of the Internal Revenue Code, which is part of the U.S. anti-boycott regime enacted in the 1970s.

The rule requires U.S. taxpayers to report when they cooperate with or receive requests to cooperate with international boycotts that the United States does not sanction.

The law primarily targets participation in the Arab League boycott of Israel, though the statute itself does not mention Israel directly.

If a taxpayer agrees to boycott requests tied to these countries, several tax consequences may follow, including:

• Loss of certain foreign tax credits

• Denial of deferral benefits for foreign income

• Mandatory reporting to the IRS

Treasury periodically publishes the country list to indicate where boycott-related requests are most likely to arise.

Countries Identified in the 2026 Treasury List

Treasury currently identifies the following jurisdictions as requiring or potentially requiring participation in an international boycott:

• Iraq

• Kuwait

• Lebanon

• Libya

• Qatar

• Saudi Arabia

• Syria

• Yemen

These countries historically participated in, or maintained elements of, the Arab League boycott framework.

The Larger Story

The anti-boycott regime is one of the older compliance structures in the U.S. international tax system.

It reflects Cold War-era geopolitical tensions rather than modern tax policy design. Yet the reporting rules remain active and enforceable.

For multinational companies operating in the Middle East, boycott requests can still appear in contracts, tender documents, or letters of credit. The IRS continues to treat these situations as reportable events.

Even when companies refuse the request, the reporting obligation can still apply.

What It Means in Practice

• Review transactions involving the listed countries for potential boycott language in contracts or trade documents.

• Report boycott requests to the IRS using Form 5713 when required.

• Confirm internal compliance teams understand that refusing a boycott request may still require reporting.

• Monitor supply chain documentation and letters of credit issued in these jurisdictions.

• Coordinate legal and tax review when operating through regional distributors or joint ventures.

Next Steps

Treasury will continue updating the boycott list as geopolitical conditions evolve. U.S. taxpayers must apply the reporting rules whenever a boycott request arises, regardless of whether the request is accepted.

One More Thing

The anti-boycott rules rarely make headlines, but they quietly impose reporting obligations on routine trade documents throughout parts of the Middle East.
