TaxRepU.S. Income Tax Guide · IRC § 7701(b)
A non-U.S. citizen who is a lawful permanent resident of the United States is generally treated as a U.S. resident alien for federal income tax purposes. The Green Card Test can apply even when the individual spends most or all of the year abroad, and U.S. tax residency generally continues until lawful permanent resident status is formally ended or a valid treaty position applies.
IRC § 7701(b)(1)(A)(i)
A non-U.S. citizen is generally a resident alien for U.S. federal income tax purposes if the individual is a lawful permanent resident of the United States at any time during the calendar year.
Lawful permanent residence is an immigration-law status. It generally exists where USCIS has granted the individual the privilege of residing permanently in the United States as an immigrant, typically evidenced by Form I-551, Permanent Resident Card — the “green card.”
For tax purposes, the important point is that the status itself controls. The physical card is evidence of status; it is not the status itself.
Green Card Test
IRC § 7701(b)(1)(A)(i) treats a lawful permanent resident as a U.S. resident alien. Treas. Reg. § 301.7701(b)-1 provides that the Green Card Test is satisfied if the individual is a lawful permanent resident at any time during the calendar year.
That resident status can have major consequences because resident aliens are generally taxed in the same manner as U.S. citizens on worldwide income.
Residency Starting Date
If the individual meets the Green Card Test but does not also meet the Substantial Presence Test, the residency starting date is generally the first day during the calendar year on which the individual is physically present in the United States as a lawful permanent resident.
If the individual also meets the Substantial Presence Test in the same year, the residency starting date is generally the earlier of the Green Card starting date and the SPT starting date.
Practical Example
An individual enters the United States as a nonimmigrant and later becomes a lawful permanent resident. If the individual does not meet the SPT earlier, the Green Card residency starting date generally begins when U.S. presence and lawful permanent resident status coincide.
If the same individual had already met the Substantial Presence Test, resident-alien status may begin before the green card was granted because the earlier SPT starting date controls.
Continuing Status
Treas. Reg. § 301.7701(b)-1 treats lawful permanent resident status as continuing unless it is rescinded or administratively or judicially determined to have been abandoned.
Accordingly, moving to Germany, renting or buying a home abroad, spending only limited time in the United States or allowing the physical card to expire does not, by itself, terminate U.S. resident-alien status.
Ending Green Card Residency
The IRS states that Green Card Test residency continues unless the individual voluntarily renounces and abandons LPR status in writing, USCIS administratively terminates the status, or a federal court judicially terminates it.
An individual may formally abandon lawful permanent resident status, commonly through the immigration procedures for surrendering LPR status. The tax consequences should be analyzed before doing so.
USCIS or the relevant immigration authorities may administratively determine that lawful permanent resident status has ended or been abandoned.
A final federal judicial determination can also terminate the status for purposes of the Green Card Test.
Long-Term Residents
For expatriation-tax purposes, a lawful permanent resident can become a “long-term resident” after meeting the statutory residence-history requirements. Treaty years may affect the count under the special rules.
If long-term resident status is terminated, the individual may need to test the net-worth, tax-liability and certification requirements under the expatriation regime and may have Form 8854 filing obligations.
IRC § 7701(b)(6) · Treaty Coordination
A lawful permanent resident can, in certain circumstances, begin to be treated as a resident of a foreign country under an applicable income tax treaty, not waive the treaty benefits and notify the IRS of that position.
For U.S. income-tax purposes, this can cause the individual to be treated as a nonresident under the treaty coordination rules even though the individual may remain an LPR for immigration purposes.
Treaty Position vs. Immigration Status
Treas. Reg. § 301.7701(b)-7 coordinates domestic resident-alien status with treaty residence. An individual who validly claims foreign treaty residence may be treated as a nonresident for U.S. income tax purposes.
A treaty position does not necessarily mean that USCIS regards the green card as abandoned. Tax and immigration consequences must be evaluated separately, particularly where the individual intends to retain the ability to live permanently in the United States.
Form 8833
A dual-resident alien claiming nonresident treatment under a treaty generally files under the special rules applicable to treaty nonresidents and discloses the treaty-based position on Form 8833.
A treaty position can affect other federal tax concepts, information reporting and long-term-resident analysis. It should not be treated as merely a return-format election.
Administrative Guidance
The statute defines resident aliens, lawful permanent residents, residency starting dates and treaty coordination.

Publication 519Relevant Case Law
Green Card residency is primarily statutory, but several cases show why formal LPR status and treaty treatment matter.
Gerd Topsnik had lived outside the United States but had not formally terminated his lawful permanent resident status under the applicable rules. The Tax Court treated him as continuing to satisfy the U.S. Green Card residency framework and separately analyzed whether the U.S.–Germany treaty changed the result.
Practical significance: Living abroad for years does not by itself terminate Green Card tax residency. Formal status and treaty residence must be analyzed separately.
The D.C. Circuit affirmed the Tax Court’s judgment rejecting Topsnik’s U.S.–Germany treaty arguments for the years at issue.
Practical significance: A taxpayer cannot simply rely on living in Germany; actual treaty residence and the legal requirements for U.S. status must be satisfied.
D.C. Circuit judgmentAroeste involved a long-standing Green Card holder and the U.S.–Mexico treaty. The district court analyzed IRC § 7701(b)(6) and concluded that foreign treaty residence, together with the statutory notification conditions, could alter the taxpayer’s treatment as a lawful permanent resident for the federal tax purpose at issue.
Practical significance: Green Card status for immigration purposes and U.S. income-tax residence can diverge where treaty rules are properly invoked.
DecisionThe decisive question is whether lawful permanent resident status exists under immigration law and how § 7701(b) treats that status for tax purposes.
Practical significance: Expired cards, long absences and foreign homes should never be used as substitutes for verifying the actual LPR and treaty status.
Practical Checklist
Determine whether lawful permanent resident status actually exists under U.S. immigration law.
Coordinate the Green Card date with U.S. physical presence and any earlier SPT starting date.
Identify when worldwide income reporting begins and which Form 1040 obligations follow.
If the individual lives abroad, determine whether a tax treaty also treats the individual as resident there.

Germany–U.S. Context
A Green Card holder who moves to Germany can remain a U.S. resident alien under domestic law while also becoming resident in Germany. The domestic U.S. analysis therefore comes first, followed by German residence and, if necessary, the Article 4 treaty tie-breaker.
