The Trump administration has proposed a change to the federal 1040 tax form that would require filers to disclose their citizenship and residency status to the Internal Revenue Service, Fox News Politics reported Monday. The proposal, first surfaced in reporting by Fox News, would add certification questions to the standard individual income tax return used by roughly 150 million American households.
The change would require taxpayers to state whether they are U.S. citizens, lawful permanent residents, or nonresident aliens, and to certify that status under penalty of perjury. It is not yet known whether the questions would be added to the printed 1040, the electronic filing system, or both, or what the effective date would be if the proposal is adopted.
According to Fox News, the measure is being advanced by the administration as a routine integrity update to the tax system. Critics, including immigration advocacy groups and Democratic lawmakers, argue the information could be shared with immigration enforcement agencies, turning the tax rolls into a de facto registry.
What the Proposal Would Do
The 1040 has long asked about filing status, dependents, and income sources, but has never required an explicit citizenship declaration. Nonresident aliens who work in the United States on visas already file separate returns — the 1040-NR — and are generally assigned an Individual Taxpayer Identification Number, or ITIN, rather than a Social Security number.
The proposed change would expand the citizenship question to the standard 1040. That means millions of filers who currently use ITINs, including undocumented immigrants who file taxes voluntarily, mixed-status families, and some foreign nationals with U.S. income, would have to identify themselves under a new certification line.
Fox News reported the administration estimates the change would improve accuracy in eligibility determinations for refundable tax credits, including the Earned Income Tax Credit and the Child Tax Credit, which are limited to filers with valid Social Security numbers. The administration has not released a cost estimate or a timeline for implementing the change.
How We Got Here
The proposal lands in the middle of a broader Trump administration overhaul of the federal government. As Fox News and other outlets have reported, the IRS has undergone steep workforce reductions since 2025 — examination and collection staffing fell by nearly 10,000 employees, according to a Treasury watchdog, and revenue collected from IRS examinations dropped about 35 percent, from roughly $10 billion in fiscal 2024 to $6.5 billion in fiscal 2025.
At the same time, the administration has pushed to cut taxpayer-funded benefits to illegal immigrants, a priority Iowa Republican Rep. Ashley Hinson highlighted in recent comments. The citizenship question on the 1040 fits that frame: if the government is going to deny benefits to people who are in the country illegally, it needs a way to tell who is who.
Former President Joe Biden's 2022 Inflation Reduction Act directed nearly $80 billion to the IRS over ten years to upgrade systems and hire enforcement staff. That build-out has been largely unwound under the current administration, leaving the agency with fewer auditors and fewer collectors — but, if the proposal goes through, a new stream of data about the immigration status of every filer.
What Critics Say
Immigration advocates argue the change would deter undocumented filers from filing at all, costing the Treasury revenue and pushing workers further into the cash economy. They also warn that any data sharing between the IRS and the Department of Homeland Security would violate long-standing expectations of taxpayer confidentiality.
The IRS has historically treated return information as confidential, with narrow exceptions for law enforcement with a court order. Whether the administration intends to seek an expansion of those exceptions is not yet known. The Department of Homeland Security, under Secretary Kristi Noem, has not announced any new data-sharing arrangement with the IRS tied to this proposal.
A Treasury Department spokesperson did not respond to a request for comment by press time. The administration has not said whether the change would be made by regulation, which would require a public comment period, or by legislation, which would need to move through a Republican-controlled Congress.
Our Take
Here is what the critics will not say out loud: the federal government already knows who is in this country illegally. It knows because people tell it — on visa applications, on asylum paperwork, in court filings. What it has never had is a single, universal declaration tied to the one form almost every working adult in America fills out. Adding a citizenship line to the 1040 is not a new surveillance power. It is an honesty requirement.
If you are a U.S. citizen, you check the box. If you are a lawful permanent resident, you check the box. If you are neither, you check the box that says so — and if that box disqualifies you from a refundable credit, that is not cruelty. That is the tax code working the way Congress wrote it. The EITC and the CTC are written for citizens and legal residents. Enforcing that is not a scandal. It is the bare minimum.
The real question is why this was not done decades ago. For years, the IRS has quietly issued ITINs to people with no legal status, processed their returns, and cut them checks — all while the same government told voters at the border that it had no way to track who was here. That contradiction is the scandal. The Trump administration is closing it.
Expect the usual chorus: the ACLU will sue, the legacy media will call it a registry, and Democrats will claim it targets families. But ask yourself one thing. If your neighbor is claiming a child tax credit for a child who does not live here, or an earned income credit filed under someone else's Social Security number, do you want the IRS to know? The answer to that question is the answer to this entire debate.
