A coalition of Democratic senators and House members announced Wednesday they are formally requesting congressional hearings into a reported Internal Revenue Service proposal to add a citizenship question to federal tax forms, escalating what had been an internal agency deliberation into a full-scale political confrontation on Capitol Hill.

The American Civil Liberties Union and National Immigration Law Center issued a joint statement Wednesday morning warning that such a question would have a chilling effect on tax compliance among immigrant communities, potentially driving millions of undocumented residents to avoid filing returns entirely — reducing federal revenue and leaving vulnerable populations without documentation of income. Tax policy advocates noted that the IRS has historically operated without citizenship data, relying on Social Security numbers and Individual Taxpayer Identification Numbers to process returns.

Senate Finance Committee Ranking Member Ron Wyden of Oregon sent a letter to Treasury Secretary Scott Bessent demanding full documentation of internal deliberations on the proposal, including any White House communications that may have prompted the idea. Wyden's office said the request was accompanied by sign-on letters from at least a dozen Democratic colleagues. On the House side, Representatives Judy Chu of California and Jimmy Gomez, both members of the Congressional Hispanic Caucus, called the proposal 'a direct attack on immigrant families disguised as tax administration reform.'

Republican supporters of the measure, meanwhile, began framing the citizenship question as a straightforward data-collection effort consistent with census practices, with several members of the House Ways and Means Committee suggesting the information could help identify tax fraud and verify eligibility for certain credits. The White House declined to confirm whether the proposal had received formal executive backing but did not distance itself from the concept.

Legal analysts said any final rule requiring citizenship disclosure on tax forms would face immediate litigation under the Administrative Procedure Act and potentially the Fifth Amendment, given that self-incrimination concerns could attach to compelled disclosure of immigration status. The controversy is expected to dominate Wednesday's congressional news cycle and may prompt committee chairs to schedule formal oversight proceedings as early as next week.
