Who pays for government when wages shrink

Five of every six federal tax dollars come from income tax and payroll tax, while the tax on company profits brings in less than one in ten.

Workers' share of national income is at or near its lowest since records began, and Yale's model says AI would lift federal revenue only about half as much as it would if workers kept their share.

The safety net already misses most of the jobless, and neither answer on the table, paying people directly or taxing the machines, is law in America.

When a company announces a layoff, the story is about the people who lose their jobs. That is the right place to start. But there is a second story under it, and most people never see it, because the money leaves their pay slip before they do.

Every job pays tax. So we went looking for the money. Where does Washington's come from? Which way was it already moving? What do the careful forecasters expect? And what is in place for the people who lose the wage?

Here is what we found. The federal government runs on wages. Workers' share of the nation's income was falling long before generative AI. The best model we found says revenue still grows, but by about half as much. And the safety net already misses most of the jobless.

In fiscal 2025, the government's accounting year, about half of everything the federal government collected came from individual income tax. Another third came from payroll taxes, the deductions for Social Security and Medicare. Together that is about five dollars in every six. Corporate tax, the tax on company profits, brought in less than one dollar in ten.

Social Security is funded almost entirely by the payroll tax: 91.3 percent of its revenue. Its retirement fund, the reserve that tops up what the tax brings in, is already projected to run dry in late 2032. Medicare's hospital fund is projected to run dry in 2033. Those dates were set before anyone modelled AI.

So the question under every AI layoff is not only what happens to the worker. It is what happens to the money for schools, pensions and hospitals if income moves from wages to profits.

By the government's own measures, workers' share of the national income is at or near the lowest since records began.

The Bureau of Labor Statistics measures the share of business income paid to workers. In the second quarter of 2026 it stood at its lowest since 1947. The Bureau of Economic Analysis measures employee pay as a share of national income. In 2025 that was 50.9 percent, the lowest since 1935. In 1970 it was 58.4 percent.

The careful forecasters do not say the tax base collapses. Yale's Budget Lab modelled AI futures under the current tax system. In the fastest case, federal revenue still rises, by up to $246 billion in fiscal 2030.

But that is only about half of what the same growth would bring if workers kept their share. The reason is that capital, the money made from owning things, is taxed more lightly than work. As AI widens the gap between owners and workers, payroll tax revenue falls.

The money does not vanish. It moves from wages, which are taxed heavily and at source, to profits and gains, which are taxed lightly and often later.

The national numbers hide the local ones, and the local loss is the easiest to see. When a large employer leaves, a town loses more than wages. It loses income tax, sales tax, property values, and the shops that depended on the workers.

We have not found a town hollowed out by a layoff its employer blamed on AI. But we know what one looks like. When Tyson closed its beef plant in Lexington, Nebraska, in January 2026, the University of Nebraska put the loss at 7,003 jobs. That meant about $3.28 billion a year in output, and $23.2 million a year in local tax alone.

"Tyson owes this community a debt," the city manager said, as the AP reported.

Before any forecast, there is a measured fact. America's safety net for the jobless already misses most of them.

Unemployment insurance is the weekly payment a laid-off worker can claim. The St. Louis Fed found in March 2026 that the share of the unemployed eligible for it ranges from 30.5 percent in Alaska to 70.3 percent in New Hampshire. Benefits replace between 42.6 and 67.1 percent of lost wages, depending on the state. The share of unemployed people who actually receive benefits fell from more than half in the 1950s to less than 30 percent, according to the Washington Center for Equitable Growth. Before a single AI layoff, most of the jobless are already outside the system.

In America, a lost job often means lost health insurance too. The Commonwealth Fund projects that the expiry of the enhanced health-insurance tax credits will cost about 339,100 jobs in 2026, and the Urban Institute estimates 4.8 million people will become uninsured. Losing the subsidy costs jobs, and losing the job costs the coverage.

People are already reaching into their retirement savings. Hardship withdrawals from 401(k) plans, the workplace retirement accounts, hit a record in 2025: 6 percent of participants, up from about 2 percent before the pandemic, in Vanguard's figures as Axios reported them.

Senator Ron Wyden announced a bill on 23 October 2026 to widen unemployment insurance for workers hit by AI. We print no number for it.

Universal basic income, a regular payment to everyone with no conditions, came back into the conversation in 2026, pushed by officials more than by chief executives. The evidence supports neither side as cleanly as each claims.

In 2017 Bill Gates suggested that a robot doing a worker's job should pay tax like the worker. In August 2026 he went further. "The tax system nudges you toward replacing people with machines," he said, as Fortune reported it.

That same month the idea reached bill text. H.R. 10044, the AI Tax and Work Protection Act, would tax AI usage at a rate that rises automatically with unemployment. It would include a company's own use of AI where it "enables or results in a reduction in the workforce."

South Korea tried a version. In 2018 it cut the tax break on automation equipment, and a 2025 study found affected firms bought fewer robots and hired more people. The European Parliament voted the idea down in 2017.

Neither answer is law in America, and each has its critics. Geoffrey Hinton, the Nobel laureate who expects mass unemployment, still rejects cash as the answer: it "won't deal with human dignity," he told the Financial Times. Senator Mike Rounds, a Republican, put the objection to the tax plainly, as Roll Call reported in June 2026: "If you start to tax it, you slow it down, and it goes elsewhere."

There is an odd feature of this debate. Some of the loudest voices for new taxes and new payments are the people building the machines. OpenAI published a paper on taxing capital. Elon Musk spoke of "universal high income," as reported. Anthropic's chief executive wrote an essay on tax, and has been reported as suggesting a tax on AI model revenue.

Disclosure: Token Runner is built with Claude, which is made by Anthropic.

Whether that is conscience, insurance or positioning, it means the question of who pays is no longer fringe. By October 2026 Congress had rival bills. The argument had moved from "should we" to "how."

There are two ways to read this, and the evidence supports both.

The first is that the tax base is quietly eroding. Washington runs on wages. Workers' share of income is already near a record low. The pension and hospital funds are already short. If AI moves more income from wages to profits, a government built on wages has to change how it collects, or spend less on the people who lost them.

The second is that the alarm runs ahead of the numbers. The careful model does not show revenue falling; it shows revenue rising, by less. The fall in workers' share began decades before generative AI. No town has yet been hollowed out by a layoff blamed on AI. And some of the loudest calls for new taxes come from the companies building the machines, whose reasons are their own.

Either way, the jobs story gets the headlines, and the tax story decides what happens next.

Our ask is simple. When the next layoff is announced, ask two questions: who lost the job, and who now pays the tax that job used to pay?
