IRS Form W-8 or W-9? “Green Card” Holders (LPRs) – Certifications Re: Tax Status after Aroeste v. United States

The author has extensively discussed the appropriate IRS Form for individuals to sign under penalties of perjury when dealing with their banks and third parties, irrespective of the banks’ location. The choice between IRS Forms W-8 and W-9 hinges on the U.S. income tax residency status of the individual. Forms W-8 and W-9 serve the purpose of conveying the tax residency status of the individual to third parties. The correct (or incorrect form) can have a range of different tax and legal consequences to the individual. A non-resident is generally not subject to income taxation in the United States, except for on limited types of income. In contrast, a resident (for federal income tax purposes) is subject to taxation on their worldwide income. If an income tax resident of the United States falsely certifies their status using Form W-8, severe adverse legal consequences can follow.

The complexity heightens for “Green Card” holders living abroad, especially those residing in countries covered by an income tax treaty with the United States. See, Aroeste v. United States, Case No. 22-cv-00682-AJB-KSC. Aroeste v United States – Order Nov 2023, emphasizes a 5-step analysis for Green Card holders who have not formally abandoned their status. The ultimate test is whether the individual is entitled to be treated as a resident of a foreign country under a tax treaty.

The impact of the Aroeste v United States decision presents a dual scenario for individuals who have not formally abandoned their “lawful permanent residency” status. On the positive side, there is an opportunity to inform the Internal Revenue Service (IRS) of their non-resident status by utilizing the applicable income tax treaty. There are specific steps to take as explained by the Court in Aroeste vs. United States. This action can relieve them of U.S. federal income tax filing obligations and Foreign Bank Account Report (FBAR) filing requirements, helping to steer clear of potential penalties and taxes that might otherwise be owed. The Court in Aroeste concluded such late filings could subject the individual ” . . . to penalties pursuant to I.R.C. § 6712(a) equal to $1,000 per failure to timely report his Treaty position. . . “

However, on the flip side, this termination of U.S. income tax residency status may lead to the individual “cease[ing] to be a lawful permanent resident of the United States (within the meaning of section 7701(b)(6)).” Such a shift can trigger adverse U.S. tax consequences, affecting not only the individual but also extending to children, spouses, family members, and friends who could receive “covered gifts” or “covered bequests.” This classification may result in the individual being deemed a “covered expatriate” under the expatriation tax law, as outlined in IRC 877A(g)(3). See, IRC 877A(g)(3). Potentially severe adverse tax consequences can follow from this edge of the sword. The Court in Aroeste vs. United States did not address these adverse tax consequences as they were not at issue.
