Update: Does the IRS have access to the USCIS immigration data for “current” and “former” lawful permanent residents (LPRs)?
This is a question that concerns those non-U.S. citizens who are aware of the IRS prior position in pursuing tax penalties and adverse tax positions against the millions of “LPRS” residing outside of the United States. The concern stems from the way the government handled cases such as Mr. Alberto Aroeste where more than $3M of information penalties were assessed when very little income tax was assessed and the U.S.- Mexico income tax treaty was ignored. See, 2023 report to Congress by the Taxpayer’s Advocate and footnote 10, reported in Most Serious Problem #9 – COMPLIANCE CHALLENGES FOR TAXPAYERS ABROAD.


Footnote #10: For a recent case illustrating the complexity of applying statutory requirements and treaty provisions, see Aroeste v. United States, No. 3:22-cv-00682, 2023 WL 8103149 (S.D. Cal. Nov. 20, 2023) (holding that a Mexican citizen with U.S. lawful permanent residency status was not a “U.S. person” required to file a Report of Foreign Bank and Financial Accounts).
A prior post explained a bit about the Treasury Department’s TECs database system. See, Should IRS use Department of Homeland Security to Track Taxpayers Overseas Re: Civil (not Criminal) Tax Matters? The IRS works with Department of Homeland Security with TECs Database to Track Movement of Taxpayers. The explanation in the IRM was updated largely in 2018.
A follow-up post will help address the question raised in the title of this post.
What Questions Need to be Asked if You Live (with a “green card”) in one of the 67 Countries – with a U.S. Income Tax Treaty?
Depending upon the factual circumstances of each individual, they may be able to benefit from the international tax treaty law articulated by the U.S. Federal District Court in Aroeste v United States – Order (Nov 2023). Future posts will explore the legal relevance of some of the following questions to consider:

-
- Does the individual reside in one of the 67 countries affected by a U.S. income tax treaty with the United States? See, DHS Report: 3.89M Emigrated LPRs — Who Falls Under the Tax Treaty Escape Hatch?
-
- Does the individual have a “green card” they never formally abandoned (has it “expired” on its face; of the document)?
-
- Was no USCIS Form I-407, Record of Abandonment of Lawful Permanent Resident filed with the U.S. federal government?
-
- If one was filed, when, from where, and how was it filed?
-
- Has the individual affirmatively filed USCIS Form – I-90, Application to Replace Permanent Resident Card (Green Card)?

-
- Has the individual filed any U.S. federal income tax returns since leaving the United States?
-
- Was a professional tax return preparer hired or consulted about the filing of a federal income tax return (e.g., a certified public accountant, an enrolled agent, a full time tax return preparer, ta tax attorney, etc.)?
-
- Has the individual been filing IRS Form 1040 Resident Tax Returns in the same way Mr. Aroeste was filing – based upon the advice (that turned out to be erroneous -although given in good faith) from their U.S. tax return preparer?

- Has the individual been filing IRS Form 1040 Resident Tax Returns in the same way Mr. Aroeste was filing – based upon the advice (that turned out to be erroneous -although given in good faith) from their U.S. tax return preparer?
-
- Has the individual been filing IRS Form 1040NR, Non-Resident Tax Returns? If so, when and how?
-
- Has the individual ever filed IRS Form 8854, Initial and Annual Expatriation Statement? If so, when and how (was it attached to a federal tax return 1040 or 1040NR)?
-
- Has the individual ever filed IRS Form 8833, Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b)?
-
- What steps if any have been taken to notify the U.S. federal government (irrespective of the agency) regarding their physical residency outside the United States?
- What steps if any have been taken to notify the U.S. federal government (irrespective of the agency) regarding their physical residency outside the United States?
This information is intended to provide general information about tax expatriation legal concepts under U.S. law to help readers better understand often very complex issues within the U.S. international tax field for citizens and lawful permanent residents. General legal information is not the same as legal advice, that is, the concrete application of law to a specific case with unique and particular facts.
Legal advice also should include strategic planning and advice to a particul
ar case. A legal adviser should be able to assist an individual in taking important decisions and steps, related to the specific goals of the individual, while understanding the legal and tax consequences of each step. There are a range of consequences that the “U.S. tax expatriation” laws impose upon different types of transactions, transfers, reorganization of assets, etc. None of these items are discussed in this Tax-Expatriation.com This is not legal advice.
Taxpayer’s Advocate Report – Highlights Massive Gap (?) in U.S. Tax Compliance for Mexican Resident Individuals (Part I of II)

Few people think about how many individuals around the world should or must file U.S. tax returns? When must they file (if ever) when they reside predominantly outside the United States? What are the legal consequences under U.S. law for not filing? This post discusses the discrepancy between the number of individuals who should file tax returns and the actual number of returns filed, particularly focusing on individuals residing in Mexico.
In addition to income tax returns, when are estate or gift tax returns required to be filed under the law of the United States? These comments do not address this question, which will be addressed in a future post.
The 2023 report to Congress by the Taxpayer’s Advocate scratches the surface of this issue in her footnote 41, reported in Most Serious Problem #9. It reads as follows when talking about the number of competent tax return professionals residing outside the United States:
For example, Thailand, a country from which 7,409 individual income tax returns were filed in TY 2021, lists only five preparers, all but one in Bangkok. Mexico, a country from which 10,929 individual income tax returns were filed in TY 2021, lists only 23 preparers. See IRS, Directory of Federal Tax Return Preparers with Credentials and Select Qualifications, https://irs.treasury.gov/rpo/rpo.jsf (last visited Dec. 18, 2023); IRS, CDW, IRTF, TYs 2016-2022 (through Sept. 28, 2023).

- Lawful Permanent Residency Population in Mexico (Emigrated from the U.S.)
How can Mexico, with nearly 1 million Mexican residents estimated to be living outside the United States without formally abandoning their “lawful permanent residency” status, have only 10,929 tax returns filed from Mexico? The DHS Office of Homeland Security Statistics report estimates approximately 3.89 million LPRs have emigrated and now reside outside the U.S., with a significant portion being Mexican.
See, DHS Report: 3.89M Emigrated LPRs — Who Falls Under the Tax Treaty Escape Hatch?
Given that around 25% of this group should on their face be United States persons (without applying the law in the U.S.-Mexico tax treaty), it raises questions about why there aren’t more Mexicans filing U.S. tax returns, many more? This does not even consider the U.S. citizen “expat” community who live in Mexico. Maybe a considerable number of the 10,929 tax returns filed from Mexico may actually originate from United States citizens working, residing, or retired in Mexico (so-called “expats”). The number of U.S. expatriates working and living in Mexico is a factor to consider, given the recent reports on thousands of U.S. citizens now working remotely from places such as Mexico City.
- U.S. Citizen Population in Mexico
According to the U.S. Department of State, roughly nine million U.S. citizens reside abroad as of 2020. See, Most Serious Problem #9, p. 118 and Consular Affairs by the Numbers:

Given this substantial “expatriate population” (including Mexicans who are dual nationals and would never consider themselves as an “expatriate”; but are more of the “accidental American” type), the discrepancy between reported tax returns and potential filings becomes even more significant. It suggests a considerable underreporting of tax returns among U.S. citizens and LPRs living abroad, specifically in Mexico.

When do I (as a resident) meet the gross income thresholds that require me to file a U.S. income tax return? Updated for 2023 Income Thresholds
In 2014, this blog explained the income thresholds relevant for filing tax returns during those years. However, the tax reform implemented in 2018, known as the Tax Cuts and Jobs Act (TCJA), brought significant changes to who is required to file tax returns based on income thresholds. So, when exactly do I reach the gross income thresholds that necessitate filing a U.S. income tax return? Old Post (2014)
These thresholds differ significantly from those in 2014 due to the TCJA passed in 2017.

That blog post detailed specific requirements applicable only to U.S. resident individual taxpayers:
Any USC individual (and any LPR who does not live in a country with a U.S. income tax treaty) is obligated under the U.S. federal tax law to file a federal income tax return IRS Form Form 1040 if they meet minimum thresholds of income. The thresholds are low, and are reached once the gross income is at least the sum of (i) the “exemption” amount (currently US$3,900 per exemption) and (ii) the “standard deduction” amount.
Accordingly, even if a USC or LPR has even a modest sum of “gross income”, which equates to at least US$10,000 (in whatever currency earned), the USC or LPR will probably have a U.S. tax return filing requirement.
Several significant developments have occurred since the publication of that blog post. First, the federal tax reform primarily applicable for the 2018 tax year, the The 2017 Tax Cuts and Jobs Act (TCJA), substantially altered various tax concepts. Specifically, the TCJA eliminated the concept of “personal exemptions” for the taxpayer, spouse, and dependents. These were previously used to calculate income thresholds determining whether a U.S. resident taxpayer had to file a tax return or not. However, they are no longer applicable. The standard deduction is now key to determine who is required to file.
A recent federal report from Congressional Research Service (CRS Report explains -Nov. 2023): Under the TCJA, basic standard deduction amounts in 2018 were nearly doubled to $12,000 for single filers, $18,000 for head of household filers, and $24,000 for married joint filers. These amounts were annually adjusted for inflation after 2018. In 2024, these amounts are $14,600, $21,900, and $29,200, respectfully.
Hence, for U.S. residents, the filing thresholds have increased substantially for those required to file U.S. tax returns: $14,600 for single filers, $21,900 for head of household filers, and $29,200 for married joint filers for the 2024 tax year.
Non-residents have a completely different rule as to when they are required to file U.S. non-resident tax returns (1040NR), which will be discussed in a later blog. A non-resident can have as little as say US$1,500 of income sourced from the United States and have an obligation to file a tax return. Totally different thresholds and totally different rules are applicable.
Countries From Which Viewers Read Posts – Tax-Expatriation.com – First Week of 2024 (Which Ones are Tax Treaty Countries?) – Applying the “Escape Hatch”
The whole idea of the “escape hatch” for tax treaties is an excellent way of explaining how and when tax treaty law applies in different circumstances. Importantly, the U.S. federal government cannot deny an individual (or presumably a company either) from properly applying the law of a tax treaty – even if they “gave [an] untimely notice of his treaty position “. See further comments at the end of this post and the District Court’s opinion here – Aroeste v United States – Order (Nov 2023). Meanwhile, see below the 22 countries from where global readers viewed Tax-Expatriation.com during the first full week of 2024.

Below is the list of 22 countries (including the United States) from where readers hailed, who read Tax-Expatriation.com during the first week of 2024. All, but Brazil, Croatia, Nigeria, the United Arab Emirates, Colombia, Kenya and Bermuda have income tax treaties with the United States.

This means that all other individuals are connected with the following 14 countries that have tax treaties with the United States:
- Mexico
- India
- Canada
- United Kingdom
- Switzerland
- Australia
- China
- Spain
- Turkey
- Germany
- Japan
- Romania
- Portugal
- Netherlands
Further, all individuals who might have never formally abandoned their lawful permanent residency (“green card”), maybe never filed specific IRS tax forms, and yet reside in one of these fourteen (14) treaty countries could be eligible for the application and the specific benefits of international income tax treaty law. This, along the lines of the decision in Aroeste v United States (Nov. 2023). In addition, there could be other tax treaty benefits applicable to those individuals in these fourteen countries depending upon where are their assets, what type of income they have, where does the income come from, and where do they reside.
The tax treaty rights discussed here are established by law, as elucidated by the Federal District Court in Aroeste v United States (Nov. 2023). The Court determined that the IRS cannot simply assert an individual’s ineligibility for treaty law provisions based solely on the failure to file specific IRS forms within the government-defined “timely” period. The Court emphasized that there is no automatic waiver of treaty benefits as a matter of law, while acknowledging: “. . . Aroeste gave untimely notice of his treaty position. . .” For specific excerpts from the opinion, please refer to the highlighted portions below. To access the complete opinion, please consult Aroeste v United States – Order (Nov 2023).
* * * * * * * * *
B. Whether Aroeste Did Not Waive the Benefits of the Treaty Applicable to Residents of Mexico and Notified the Secretary of Commencement of Such Treatment.
To establish Mexican residency under the Treaty, and thus avoid the reporting requirements of “United States persons,” Aroeste must have filed a timely income tax return as a non-resident (Form 1040NR) with a Form 8833, Treaty-Based Return Position Case 3:22-cv-00682-AJB-KSC Document 90 Filed 11/20/23 PageID.2722 Page 8 of 17 9 22-cv-00682-AJB-KSC Disclosure Under Section 6114 or 7701(b). Indeed, Aroeste did not submit Form 8833 to notify the IRS of his desired treaty position for the years 2012 and 2013 until October 12, 2016, when he submitted an amended tax return for both years at issue. (Id.) The Government asserts that because Aroeste did not timely submit these forms, he cannot establish that he notified the IRS of his desire to be treated solely as a resident of Mexico and not waive the benefits of the Treaty. (Id. at 4.) The Government relies upon United States v. Little, 828 Fed. App’x 34 (2d Cir. 2020) (“Little II”), a criminal appeal in which the court held a lawful permanent resident of a foreign country was a “‘resident alien’ or ‘person subject to the jurisdiction of the United States’ with an obligation to file an FBAR.” Id. at 38 (quoting 31 C.F.R. § 1010.350(a), (b)(2)).
In response, Aroeste asserts that while he agrees with the Government that I.R.C. § 6114 requires disclosure of a treaty position, he disagrees as to the consequences for a taxpayer’s failure to timely file the disclosure. (Doc. No. 75-1 at 6.) While the Government asserts the failure to timely file Forms 1040NR and 8833 deprives individuals of the Treaty benefits provided, Aroeste argues instead that I.R.C. § 6712 provides explicit consequences for failure to comply with § 6114. Specifically, § 6712 states that “[i]f a taxpayer fails to meet the requirements of section 6114, there is hereby imposed a penalty equal to $1,000 . . . on each such failure.” I.R.C. § 6712(a). Based on the foregoing, Aroeste argues the taxpayer does not lose the benefits or application of the treaty law.1 (Doc. No. 75-1 at 6.) In United States v. Little, 12-cr-647 (PKC), 2017 WL 1743837, at *5 (S.D. N.Y. 1 Aroeste further asserts that published agency guidance, letter rulings, and technical advice support his position. (Doc. No. 75-1 at 7.) For example, in 2007, an IRS agent sought advice from IRS Counsel asking, “Do we have legal authority to deny a tax treaty because Form 8833 is not attached or the treaty is claimed on the wrong Form (1040EZ or 1040)?” Legal Advice Issued to Program Managers During 2007 Document Number 2007-01188, IRS. IRS Counsel responded, “No, you cannot deny treaty benefits if the taxpayer is entitled to them. You may impose a penalty of $1,000 under section 6712 of the Code on an individual who is obligated to file and does not.” Id. As to this, the Court finds it has no precedential value under I.R.C. § 6110(k)(3), which states that “a written determination may not be used or cited as precedent.” See Amtel, Inc. v. United States, 31 Fed. Cl. 598, 602 (1994) (“The [Internal Revenue] Code specifically precludes [plaintiff] and the court from using or citing a technical advice memorandum as precedent.”) Case 3:22-cv-00682-AJB-KSC Document 90 Filed 11/20/23 PageID.2723 Page 9 of 17 10 22-cv-00682-AJB-KSC May 3, 2017) (“Little I”), a criminal case for the plaintiff’s willful failure to file tax returns, the court stated the plaintiff’s same argument “that the failure to take a Treaty position can result only in a financial penalty also lacks merit. 26 U.S.C. § 6712(c) expressly states that ‘[t]he penalty imposed by this section shall be in addition to any other penalty imposed by law.’” (emphasis added).
I have been consulted over the years by other taxpayers which are cited now as published decisions by the government and the Federal District Court (Southern District of California). These cases are referenced and cited in my own most recent case of Aroeste v United States (Nov. 2023).

However, in Little I, the plaintiff never attempted to take a treaty position. Next, in Shnier v. United States, 151 Fed. Cl. 1, 21 (2020), the court denied the plaintiffs’ claims for relief based on tax treaties because they failed to disclose a treaty based position on their tax returns pursuant to I.R.C. § 6114 “and did not attempt to cure this omission in their briefing[.]” Although the plaintiffs in Shnier were naturalized U.S. citizens who attempted to recover their income taxes under I.R.C § 1297, the court’s brief discussion of I.R.C. § 6114 in relation to a treaty-based position is instructive that an untimely notice of a treaty position does not bar the individual from taking such position. Moreover, in Pekar v. C.I.R., 113 T.C. 158 (1999), the court noted that a taxpayer who fails to disclose a treaty-based position as required by § 6114 is subject to the $1,000 penalty, but stated “there is no indication that this failure estops a taxpayer from taking such a position.” Id. at 161 n.5.2 The Court agrees with Aroeste.
Although Aroeste gave untimely notice of his treaty position, the Court finds this does not waive the benefits of the Treaty as asserted by the Government. Rather, I.R.C. § 6712 provides the consequences for failure to comply with I.R.C. § 6114, namely a penalty of $1,000 for each failure to meet § 6114’s requirements of disclosing a treaty position.
* * * * * * * * *
For individuals living in any of these 14 tax treaty countries (or any of the total 67 income tax treaty countries), the key takeaway is that, based on their specific circumstances, they might be eligible to leverage the international tax treaty principles outlined in the Aroeste v United States case (Nov. 2023). The forthcoming post will pose questions for consideration by the potentially millions of individuals affected by these rules of law.
