One Big Beautiful Bill Act (OBBBA) 2026: What Foreign-Owned U.S. LLC Owners Must Know

Written and reviewed by Arik Rozen, CPA, MBA — Head of Tax Filing Department, Form5472.online | Virginia Board of Accountancy License number #025991

What Is the One Big Beautiful Bill Act?

The One Big Beautiful Bill Act (OBBBA) was signed into law on July 4, 2025, as Public Law 119-21. While most of the legislation addresses domestic tax changes, three provisions directly affect foreign-owned U.S. entities — including single-member LLCs, multi-member LLCs, and corporations with 25% or more foreign ownership.

If you own a U.S. LLC as a non-resident, this guide explains what changed, what it means for your filing obligations, and what you need to do before your next deadline.

Change 1 — The 1% Remittance Transfer Tax (Effective January 1, 2026)

Under new Section 4475 of the Internal Revenue Code, a 1% excise tax now applies to certain cross-border money transfers sent from the United States to recipients in foreign countries.

Which Transfers Are Affected?

The tax applies when funds are sent via cash, money order, cashier's check, or similar physical instruments through a remittance transfer provider. Electronic transfers funded by a U.S. debit or credit card are currently excluded under the proposed Treasury regulations issued April 2026.

What This Means for Foreign-Owned LLC Owners

If your U.S. LLC regularly transfers funds to your foreign bank account through wire transfers or money transfer services, those transfers may be subject to the 1% excise tax. On $100,000 in annual transfers, that is $1,000 in additional tax. On $500,000, it is $5,000.

The remittance transfer provider is required to collect the tax from the sender at the time of transfer. If the provider fails to collect it, the liability transfers to the provider — but the underlying sender remains responsible for ensuring the transfer is properly reported.

Quarterly Reporting Requirement

The remittance transfer tax is reported on Form 720, Quarterly Federal Excise Tax Return. Semimonthly deposits began January 29, 2026. The IRS issued Notice 2025-55 providing limited penalty relief for providers who failed to deposit the correct amount during the first three quarters of 2026 while regulations were being finalized.

Change 2 — Updated Foreign Taxpayer Identification Number (FTIN) Requirements

The OBBBA tightened Foreign Taxpayer Identification Number requirements on Forms W-8BEN and W-8BEN-E. These are the forms that foreign individuals and entities submit to U.S. payment processors, marketplaces, and financial institutions to certify their foreign status and tax treatment.

What Changed

Under the updated rules, payment processors and marketplaces — including Amazon, Stripe, PayPal, Shopify Payments, and Walmart — are required to validate FTINs more rigorously. If your FTIN on file is expired, invalid, or missing, the platform may apply 30% backup withholding on U.S.-source payments made to your account.

Action Required

If you receive payments through any U.S. platform, verify that your W-8BEN or W-8BEN-E on file is current and that your FTIN is valid under the updated OBBBA standards. This is especially important for e-commerce sellers, SaaS founders, and service providers receiving U.S.-source income through marketplace platforms.

Change 3 — Stricter IRS Enforcement for Form 5472 in 2026

The OBBBA did not change the Form 5472 filing requirement itself. However, 2026 marks the year the IRS significantly expanded its automated enforcement infrastructure for international information returns.

The combination of expanded FinCEN data sharing and automated penalty notice systems means that previously overlooked late Form 5472 filings are now being identified and penalized faster than at any prior point. The $25,000 automatic penalty for a missing or late Form 5472 has not changed. What has changed is the speed at which the IRS identifies non-compliant entities and issues notices.

The Window for Voluntary Compliance Is Closing

For foreign-owned LLC owners who missed prior year Form 5472 filings, the IRS has historically accepted voluntary late filings accompanied by a professional Reasonable Cause statement, which can result in full penalty abatement. That window — filing before an automated notice arrives — is narrowing in 2026. Acting before a notice is issued gives your CPA significantly more leverage in requesting abatement.

Does the OBBBA Change My Form 5472 Filing Requirement?

No. The Form 5472 filing requirement for foreign-owned single-member LLCs was established under the 2017 Tax Cuts and Jobs Act regulations and remains fully in effect and unchanged under the OBBBA.

If you own a foreign-owned U.S. LLC, you are still required to file Form 5472 attached to a pro forma Form 1120 by April 15 each year, regardless of income or business activity. The OBBBA adds the remittance tax and FTIN requirements on top of — not instead of — your existing Form 5472 obligation.

2026 Compliance Checklist for Foreign-Owned LLC Owners

Use this checklist to verify your compliance status under the current 2026 rules:

- File Form 5472 and pro forma Form 1120 by April 15, 2026 (or October 15 with Form 7004 extension)

- Verify your FTIN is valid on all W-8BEN or W-8BEN-E forms on file with U.S. platforms

- Determine whether your cross-border money transfers trigger the 1% OBBBA remittance tax

- Report applicable remittance transfers on Form 720 quarterly

- If you missed prior year Form 5472 filings, file immediately with a Reasonable Cause statement before an IRS notice arrives

- Confirm your EIN is active and your entity is in good standing with the IRS
