« Back to Glossary Index

A dual-status taxpayer is a non-U.S. citizen who is both a U.S. resident alien and a nonresident alien in the same tax year. This often happens in the year someone moves to the United States, leaves the United States, gets a green card, gives up a green card, or changes tax residency under the Substantial Presence Test.

Why it matters for U.S. expats

Dual-status tax years can affect which income is taxable by the U.S., which tax form is filed, whether worldwide income must be reported for part of the year, and whether treaty positions or foreign tax credits apply. The filing rules are more complicated than a normal Form 1040 or Form 1040-NR because the taxpayer may need to split the year between resident and nonresident periods.

Common questions

1. When does someone become a dual-status taxpayer?

Someone becomes a dual-status taxpayer when their U.S. tax residency starts or ends during the tax year, creating both a resident alien period and a nonresident alien period.

2. Can U.S. citizens be dual-status taxpayers?

No. U.S. citizens are not dual-status taxpayers. The term applies to aliens who are resident aliens for part of the year and nonresident aliens for part of the year.

3. How does a green card affect dual-status taxpayer status?

A green card can start U.S. resident alien status. Giving up or losing a green card can end resident alien status and create a dual-status year.

4. How does the Substantial Presence Test affect dual-status taxpayer status?

Meeting the Substantial Presence Test can start U.S. resident alien status during the year. Leaving the U.S. and ending residency can create a dual-status year.

5. What forms does a dual-status taxpayer file?

A dual-status taxpayer usually files Form 1040 or Form 1040-NR with a statement attached for the other part of the year. The correct main form depends on whether the taxpayer is a resident or nonresident on the last day of the tax year.

6. Is worldwide income taxed in a dual-status year?

Worldwide income is taxed during the resident alien part of the year. During the nonresident alien part of the year, U.S. tax usually applies only to U.S.-source income and income connected with a U.S. trade or business.

7. Can a dual-status taxpayer claim the standard deduction?

No. Dual-status taxpayers cannot claim the standard deduction, except in limited treaty-based situations.

8. Can dual-status taxpayers file jointly?

Dual-status taxpayers cannot file a joint return unless they make a valid election to be treated as a U.S. resident for the full year.

9. Can tax treaties affect a dual-status return?

Yes. A tax treaty can affect whether income is taxable by the U.S., but treaty positions may need to be disclosed on Form 8833.

10. Is a dual-status return the same as an expat tax return?

No. An expat tax return is filed by a U.S. citizen or resident alien living abroad. A dual-status return is filed by a non-U.S. citizen whose U.S. tax residency changed during the year.

When to get help

Professional guidance is important when:

  • You moved to or from the U.S. during the tax year.
  • You received, abandoned, or lost a green card.
  • You met the Substantial Presence Test for only part of the year.
  • You need to split income between resident and nonresident periods.
  • You want to make a full-year resident election with a spouse.
  • You need to claim a tax treaty position.
  • You are unsure whether to file Form 1040, Form 1040-NR, or both.
