What Happened

A new report from the Congressional Research Service (CRS), the nonpartisan research arm of Congress, finds that decades of economic research still cannot answer a basic question: when the government taxes corporations, who actually pays? The answer matters because it determines whether the corporate income tax hits wealthy investors or everyday workers harder. [](#ngr-a0e83d0b-2705-4912-bcf5-3735cc920af1)

The CRS report reviewed a wide body of studies and found the results wildly conflicting, with no reliable consensus on how much of the corporate tax burden falls on wages versus investment returns. Congress is actively debating the corporate tax rate right now, and the answer shapes who wins and who pays.

Why Does it Matter to Me

If corporations pass their tax costs onto workers through lower wages, the corporate tax functions more like a tax on everyday paychecks, hitting lower- and middle-income earners harder. If the burden stays with investors and shareholders, who tend to be higher earners, the tax is more progressive, meaning wealthier people bear more of the cost.

The Tax Cuts and Jobs Act of 2017 cut the corporate tax rate from 35 percent to 21 percent. A study by Kennedy et al. (2024) found that 49 percent of the wage benefits from that 2017 tax cut went to chief officers and the top 10 percent of workers, with no measurable effect on the bottom 90 percent.

Whether a future rate change helps your paycheck or mostly benefits your boss depends entirely on which economic model turns out to be right.

Both Sides, Now

One study by Hassett and Mathur found that each dollar increase in corporate taxes reduces wages by $22 to $26, though a revised version of that same study later put the figure at $13. Some economic models, under their most favorable assumptions for labor bearing the burden, suggest workers could bear as much as 70 to 74 percent of the corporate tax burden.

On the other side, the Congressional Budget Office and the Joint Committee on Taxation assign 75 percent of the corporate tax burden to capital owners, not workers. A 2007 CRS reanalysis of the Hassett and Mathur findings concluded that once wages were adjusted for purchasing power and other corrections were applied, the wage effect became statistically insignificant.

The CRS report also flagged publication bias as a problem: studies that find no effect are less likely to be published, which may skew the overall body of research toward overstating the tax's impact on wages. In other words, the pile of studies lawmakers cite may not reflect the full picture.

What Happens Next?

The Tax Cuts and Jobs Act of 2017 reduced the corporate tax rate from 35 percent to 21 percent in 2018. The CRS report does not recommend a specific rate or policy, but its findings land directly in that debate.

Lawmakers on both sides will cite competing studies to support their positions. The Legis1 platform is tracking legislative activity tied to the corporate tax debate as it moves through Congress.
