Every spring, the tax form arrives like an unwelcome but familiar ritual. It asks about income, deductions, children, education, health insurance, charitable gifts—but never about the legality of your presence in the United States. That could change. The Trump administration has proposed requiring every taxpayer to answer a new question on the IRS 1040 form: whether they and their spouse are U.S. citizens, U.S. nationals, or aliens lawfully authorized to work in the country. A draft of the 2026 form, posted in late August, includes “Yes” and “No” checkboxes for the filer and for the spouse, and the answer would be submitted under penalty of law, meaning a false statement could be prosecuted as a felony. The administration says the question is meant to keep undocumented immigrants from claiming refundable tax credits such as the Earned Income Tax Credit and the Additional Child Tax Credit, and officials argue that blocking ineligible claims could save taxpayers up to $2 billion. Refundable credits are not just deductions; they can put money back into the pockets of low- and middle-income families, often providing a financial lifeline after a year of work. If the proposal is adopted, tax filing will no longer be purely about money. It will become a declaration of belonging, a moment when every worker must prove to the IRS that they are not only reporting their income, but also asserting their legal status. That is far more consequential than an extra line on a form.
The technical details of the proposal only add to its significance. The draft 1040 would ask, in plain language: “At the time you file your return, are you, and your spouse if filing jointly, a U.S. citizen, U.S. national, or an alien lawfully authorized to work in the U.S.?” A second draft form, Schedule 3-A, which is used by taxpayers to claim refundable credits, contains a similar question. The questions would be embedded in a document that already requires a signature under penalty of perjury, so every taxpayer would have to certify their immigration status or citizenship every single year. The Treasury Department has stated that the information collected will be “subject to a variety of privacy, disclosure and other legal protections,” but officials have declined to say whether the data would be shared with Immigration and Customs Enforcement to identify people for arrest and deportation. That silence is not a small footnote. The administration has already tried to connect the IRS to its immigration agenda. Last year, the Treasury Department agreed to share confidential taxpayer information of migrants with ICE; a federal judge blocked the arrangement after ruling that it violated federal taxpayer privacy laws, but not before the IRS had already given ICE the addresses of 47,000 people. That history makes it difficult to believe that the citizenship question is just about eligibility for tax credits. For many families, the question becomes: will the IRS keep this secret, or will answering honestly turn me into a target?
One of the most overlooked facts in this debate is that undocumented immigrants, by and large, already pay taxes. Because they cannot obtain Social Security numbers, many use Individual Tax Identification Numbers, or ITINs, to file federal returns. In 2024, the National Taxpayer Advocate found that roughly 3.8 million tax returns were filed using ITINs. IRS data shows that those taxpayers paid $14.4 billion in income taxes and another $6.5 billion in Social Security and Medicare taxes. That last number is especially striking because undocumented workers often pay into the Social Security system for years and yet cannot collect benefits unless they later gain legal status that makes them eligible. They contribute to the country’s tax base, to its infrastructure, to its schools, and to its social safety net, but they are generally barred from the Earned Income Tax Credit because that credit requires a valid Social Security number. The administration’s proposal, however, does not stop at enforcing that existing rule. It would apply the standards of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996—the sweeping welfare law that defines which noncitizens are “qualified aliens” for public benefits—to refundable tax credits. That is a fundamental change. It would transform parts of the tax code into a welfare-eligibility system, with the IRS acting as an immigration-status gatekeeper. The result would be a new layer of requirements that is far more complex, far more personal, and far more invasive than anything taxpayers have seen before.
The human consequences would be devastating for many families, and not just those with undocumented members. The proposal would also strip eligibility from immigrants who are lawfully present in the United States, including people with Deferred Action for Childhood Arrivals, people with Temporary Protected Status, and even temporary workers in the country on H-1B visas. Researchers from Boston University, Columbia University, and the Institute on Taxation and Economic Policy have estimated that 671,000 people, including 309,000 children, would lose the Earned Income Tax Credit under the proposal. Another 1.1 million people, including 574,000 children, would lose the Additional Child Tax Credit. Most of the affected children are U.S. citizens. They were born in the United States and hold U.S. citizenship, but because at least one of their parents is not a citizen or lawful permanent resident, they would become ineligible for credits that help pay for food, clothing, school supplies, and monthly bills. For these families, the tax return is often the one time each year when they receive a meaningful refund that can ease months of financial strain. Taking away that support would push more children into poverty, increase housing instability, and deepen food insecurity. The paperwork design might seem neutral and administrative, but the real-world effect is child hunger, eviction notices, and parents forced to make impossible choices. A checkbox that looks small in Washington, D.C., feels enormous in a kitchen in Texas, Florida, or California.
Critics of the policy say that is precisely the point. David Bier, director of immigration studies at the libertarian Cato Institute, told The Associated Press: “It could be used as an immigration enforcement tool and that is probably the reason why they are doing this.” The dilemma for an undocumented immigrant would be impossible. If they check “No,” they are admitting in a sworn federal form that they are in the country unlawfully, and that admission could be used by immigration authorities to arrest and deport them. If they check “Yes,” they are lying on a tax return, which is a felony. And if they choose not to file, they are abandoning the tax system they previously participated in, potentially forfeiting years of compliance and exposing themselves to penalties. There is no good answer. Nina Olson, executive director of the Center for Taxpayer Rights, said the proposal is “dragging the IRS into this administration’s immigration policies.” The fear is not just about privacy; it is about the fundamental relationship between the taxpayer and the government. The IRS relies on voluntary compliance—people filing honestly because they trust the system. When the tax form becomes a trap, that trust vanishes. Immigrants who would otherwise pay taxes may decide to disappear from the tax rolls entirely, reducing the very revenue the government claims to protect. The proposal could save $2 billion on paper while costing far more in lost tax payments, social trust, and human dignity.
The administration and its supporters would frame all of this as a matter of common-sense fairness. Undocumented immigrants, they argue, should not receive taxpayer-funded benefits they have no legal right to, and every dollar paid to someone ineligible is a dollar taken from citizens who follow the rules. That is a legitimate perspective, and it is true that the tax code already contains eligibility rules for credits based on citizenship and lawful presence. But the way this proposal has been crafted goes beyond enforcement. It embeds immigration enforcement into the most intimate financial document most people sign, without clear answers about data sharing and with a recent history of the IRS already handing taxpayer addresses to ICE. A tax return is not just a piece of paper; it is how a worker claims their wages, how a parent claims a child, how a struggling family receives a refund that keeps the lights on. Placing a citizenship question at the center of that process changes what it means to file. It tells millions of people that the government is watching not only for mathematical mistakes, but for people who do not belong. If the proposal moves forward, taxpayers will be forced to ask a question they never expected to see on a form: “Am I allowed to be here?” And for some, the only safe answer will be to step out of the system entirely—taking their taxes, their work, and their humanity beyond the reach of a country that once asked for their tax dollars, but now only asks for their papers. That is a heavy price to pay for a checkbox.
