IRS considers citizenship question on tax forms amid immigration enforcement push

• IRS is weighing two versions of Form 1040 for 2027, one including a citizenship checkbox
• Proposal follows legal battle over IRS illegally sharing data of 42,000 taxpayers with DHS
• Federal judge blocked data-sharing in November 2025; government has appealed
• Tax compliance among immigrant communities declining due to fear, risking $313 billion revenue loss
• Critics warn proposal could turn IRS from tax collection agency into immigration enforcement tool

The Internal Revenue Service (IRS) is debating whether to require taxpayers to disclose their citizenship status on next year’s federal tax forms, according to three people familiar with internal deliberations, as the Trump administration intensifies efforts to coordinate federal tax collection with immigration enforcement operations.

IRS officials are reviewing two versions of Form 1040, the standard document individuals use to report income and claim deductions or credits. One version contains routine updates reflecting changes in tax law. The second includes those updates and an additional field instructing filers to “Check this box if you are a non-U.S. citizen or have dual citizenship,” the sources said, speaking on condition of anonymity due to fear of professional reprisal.

The Treasury Department, which oversees the IRS, declined to comment.

From revenue collection to enforcement arm

The potential citizenship disclosure requirement marks a significant departure from the IRS’s traditional role as a neutral revenue collection agency. For decades, the agency has maintained strict confidentiality protections for taxpayer information, with unauthorized disclosures carrying penalties including imprisonment.

The shift toward using tax records for immigration enforcement follows the Trump administration’s broader efforts to link federal agencies in its deportation campaign. Throughout 2025, the Treasury Department and Department of Homeland Security pursued agreements to share confidential taxpayer data with immigration officials.

A federal judge blocked that data-sharing arrangement in November 2025. The government has appealed. In February 2026, the IRS admitted in court filings that it had improperly shared data connected to more than 42,000 taxpayers with DHS.

Legal and privacy concerns mount

Disclosing taxpayer personal information—including names or addresses—outside narrow legal exceptions carries stiff penalties, including prison time. President Donald Trump himself recently dropped a $10 billion lawsuit against the IRS after a contractor leaked his tax returns to media outlets; the contractor is serving a five-year sentence.

The Justice Department created a nearly $1.8 billion fund to compensate victims of “government weaponization” as part of that settlement. Acting Attorney General Todd Blanche signed an agreement permanently barring the IRS from pursuing tax claims against Trump, his family or his businesses.

Critics argue the citizenship question could transform the IRS into an immigration enforcement arm. “It’s another step of turning the IRS into an agency that collaborates with immigration authorities,” said Nina Olson, executive director of the Center for Taxpayer Rights, which filed the lawsuit blocking data-sharing.

Economic consequences: Fear driving down compliance

The proposal comes amid growing evidence that immigrant communities are already avoiding tax filing due to fear. Tax preparers nationwide reported frightened clients in 2025 after revelations of IRS collaboration with immigration enforcement.

The fiscal consequences are substantial. The Yale Budget Lab estimated lower tax compliance rates among immigrant communities could lead to a $313 billion loss in federal revenue over the next decade.

Under current law, foreign nationals residing in the United States—including those living in the country illegally—are required to file taxes and use the same IRS forms as citizens. Non-citizens pay into Social Security, Medicare and other programs through income, payroll and sales taxes, even though federal law prohibits undocumented immigrants from receiving most of those benefits.

What comes next

IRS officials are also considering alternative methods to determine taxpayer citizenship status. Non-citizens currently file taxes using nine-digit “individual tax identification numbers” instead of Social Security numbers. Tax officials have discussed creating differentiated codes to denote a filer’s immigration status, the sources said.

No final decision regarding the proposed Form 1040 revisions has been publicly announced. The agency’s deliberations come as federal courts continue to weigh the legality of using tax records for immigration enforcement—a question that may ultimately reach the Supreme Court.

The citizenship question debate underscores a fundamental tension: whether the IRS should remain a neutral tax collection agency or become a partner in federal immigration enforcement, with potentially billions in revenue at stake.
