WASHINGTON — A new economic analysis warns that the Internal Revenue Service could lose up to $479 billion in tax revenue over the next decade as immigrant workers facing deportation withdraw from the formal economy, reducing payroll participation and taxable income nationwide.
The estimate, compiled by independent fiscal experts and reviewed by several former Treasury officials, suggests that heightened immigration enforcement could have far‑reaching consequences for federal revenue collection and labor‑market stability.
“When large segments of the workforce move underground, the tax base shrinks dramatically,” said one senior economist involved in the study. “This isn’t just a humanitarian issue — it’s a fiscal one.”
How Deportations Affect Tax Revenue
The analysis projects that deportations and voluntary departures will lead millions of undocumented and mixed‑status workers to disengage from formal employment, shifting toward cash‑based or informal labor arrangements that are harder to track and tax.
Key factors driving the projected losses include:
- Reduced payroll tax contributions as workers leave registered employment
- Declines in income‑tax filings among households fearing exposure
- Lower consumer spending and business receipts in immigrant‑dense communities
- Ripple effects on Social Security and Medicare trust‑fund inflows
Economists say the combined impact could amount to nearly half a trillion dollars in lost federal revenue by 2036.
Broader Economic Implications
Beyond the IRS, analysts warn that the shift could depress local economies, particularly in states with large immigrant workforces such as California, Texas, Florida, and New York. Construction, agriculture, hospitality, and healthcare are among the sectors most exposed.
“These workers contribute billions in taxes every year,” said a former IRS policy adviser. “If enforcement drives them out of the system, the losses compound across every level of government.”
The report also notes that undocumented immigrants currently pay an estimated $11–13 billion annually in state and local taxes — revenue that could decline sharply if deportations accelerate.
Political and Policy Reactions
Administration officials have not commented directly on the report but have defended current enforcement policies as necessary for national security and rule of law. Democratic lawmakers and immigrant‑rights groups argue that the findings highlight the economic costs of mass deportation and call for expanded legal pathways to keep workers in the tax system.
Republican leaders counter that the long‑term fiscal benefits of stricter border control outweigh short‑term revenue losses.
What Comes Next
The study’s authors recommend that the Treasury Department and IRS conduct a formal impact assessment to quantify potential revenue declines and explore strategies to preserve compliance among remaining immigrant workers.
For now, the projection underscores a growing tension between immigration enforcement and fiscal sustainability — a debate that could shape both economic and political agendas in the years ahead.
