Introduction to the Legislative Package

The U.S. Congress is currently debating a legislative package called “The One, Big, Beautiful Bill,” which aims to reform the Internal Revenue Code by introducing a tax on remittances sent from the United States (U.S.) to foreign countries.

Understanding the Proposed Tax

This special service tax would apply at a rate of 3.5% on the amount remitted abroad, targeting individuals with irregular migration status. It’s crucial to note that this tax does not affect the recipients in foreign countries, who receive the full amount. The tax will take effect starting from 2026 and could potentially generate around $1.75 billion annually for the U.S., particularly in remittances to Mexico.

Who is Affected and How?

Any person sending money abroad could be subject to this tax, but U.S. nationals or citizens can qualify as validated senders and be exempt, or they can offset the remittance tax against other U.S. taxes owed. Those without U.S. tax liability won’t be able to claim a refund, effectively making it a permanent tax.

Mexican Perspective and Concerns

The Mexican government and legislators have expressed concern over this burdensome measure, claiming it’s discriminatory according to the U.S.-Mexico tax treaty and results in double taxation. However, these concerns may be imprecise.

Tax Treaty Analysis

Article 25 of the tax treaty prohibits differential treatment of Mexican nationals compared to U.S. nationals under similar circumstances. The treaty acknowledges that residents of each country are not in the same conditions, allowing both nations to have distinct tax regimes for residents versus non-residents.

Double Taxation Argument

The double taxation argument is unfounded since this isn’t an income tax. If a Mexican worker had already paid taxes in the U.S., they could opt for the offset mentioned earlier.

Potential Conflicts with T-MEC

As remittances are cross-border financial services, this tax might violate several T-MEC provisions related to free money transfers (Article 15.12.1) and the principle of non-discrimination in financial services (Articles 17.1 and 17.3). These regulations, which usually exclude tax measures (Article 32.3.6(b)), may apply due to the tax not being covered by the tax treaty.
