IRS Weighs Adding Citizenship Question to 2027 Form 1040

(UNITED STATES) — U.S. tax officials are considering adding a citizenship disclosure to the 2027 `Form 1040`, a step that would place immigration status on the Internal Revenue Service’s main individual income tax return as the administration expands information sharing across federal agencies.

Two versions of the return are under discussion as of May 22, 2026. One would make standard updates tied to changes in tax law. The other would add a checkbox that reads: “Check this box if you are a non-U.S. citizen or have dual citizenship.”

Treasury declined to comment on May 22, 2026. The IRS has not issued a formal announcement on the proposal.

The possible addition of a citizenship question comes as immigration agencies sharpened their public focus on status verification in May 2026. U.S. Citizenship and Immigration Services issued policy memorandum PM-602-0199 on May 21, 2026, setting out a broader policy backdrop for tighter coordination between immigration screening and federal records.

Zach Kahler, a USCIS spokesman, said on May 22, 2026: “We’re returning to the original intent of the law to ensure aliens navigate our nation’s immigration system properly. From now on, an alien who is in the U.S. temporarily and wants a Green Card must return to their home country to apply, except in extraordinary circumstances.”

Kahler tied that approach directly to enforcement. “When aliens apply from their home country, it reduces the need to find and remove those who decide to slip into the shadows and remain in the U.S. illegally after being denied residency.”

The debate over the 2027 `Form 1040` also follows tax changes enacted in the One Big Beautiful Bill Act, or OBBBA, signed as Public Law 119-21 on July 4, 2025. That law tightened several tax provisions affecting non-citizens and mixed-status households, linking tax benefits more closely to immigration and identity records.

Under the law, both parents must have a valid Social Security Number to claim the Child Tax Credit. Families that file with an Individual Taxpayer Identification Number, or ITIN, are affected by that rule, which excludes children in households where parents do not meet the Social Security Number requirement.

OBBBA also restricted access to the American Opportunity Tax Credit and the Lifetime Learning Credit for non-citizens. Another provision created a 1% excise tax on cash remittance transfers beginning Jan. 1, 2026, requiring IRS tracking of certain cross-border financial movements.

The Internal Revenue Service has already faced scrutiny over how taxpayer information is shared with immigration authorities. In April 2025, Treasury and the Department of Homeland Security signed a memorandum of understanding to share taxpayer data for deportation assistance.

That arrangement drew sharper attention in February 2026, when IRS Chief Risk and Control Officer Dottie Romo admitted in court filings that the agency had erroneously shared data on 42,000 to 47,000 taxpayers with DHS, including records tied to people who lacked sufficient identification.

A federal judge in Massachusetts blocked the IRS from disclosing residential addresses to Immigration and Customs Enforcement in November 2025. The government is appealing that ruling.

The proposed checkbox on `Form 1040` would extend those concerns beyond unauthorized immigrants. It would apply not only to non-U.S. citizens, but also to people with dual citizenship, expanding data collection to millions of U.S. citizens who hold a second passport.

That breadth matters for tax administration as well as immigration enforcement. A checkbox on the main federal tax return would move citizenship status into a form filed annually by tens of millions of households, making the disclosure part of the routine process overseen by the Internal Revenue Service rather than a separate immigration filing.

Among non-citizens and ITIN filers, one concern is whether a citizenship question would change filing behavior. The Yale Budget Lab estimated in May 2026 that if the question lowers compliance in immigrant communities, federal revenue would fall by $313 billion over the next decade.

Green Card holders face a different risk. Advocates say any mismatch between tax filings and immigration records can be used as evidence of “abandonment of residence” during naturalization proceedings tied to `Form N-400`.

That concern reflects the way separate federal files can intersect. Tax returns, residence histories and immigration applications are usually handled under different legal frameworks, but the administration’s current policy direction points toward more frequent cross-checking for fraud and enforcement.

The wording under discussion also raises a narrower issue for dual nationals who are U.S. citizens. A form prompt that asks whether a filer is a non-U.S. citizen or has dual citizenship would gather information about a category of taxpayers that includes citizens with no immigration violation and no pending status request.

No final decision has been announced on which version of the 2027 `Form 1040` the IRS will adopt. Deliberations were reported as active on May 22, 2026, with one path limited to standard tax-law updates and the other adding the citizenship question.

The administration’s broader posture is already visible in agency statements and recent law. USCIS has framed new restrictions as a return to the “original intent of the law,” while tax legislation passed in 2025 has tied several credits and transfers more tightly to citizenship, Social Security numbers and federal tracking.

Public updates from the agencies continue to appear in the [USCIS newsroom](https://www.uscis.gov/newsroom) and the [IRS newsroom](https://www.irs.gov/newsroom). Treasury’s summary of the new tax law, including the [One Big Beautiful Bill provisions](https://www.irs.gov/newsroom/one-big-beautiful-bill-provisions), sets out the same shift in black-letter terms: immigration status, taxpayer identity and eligibility for federal tax benefits are moving closer together on paper.
