Senate Democrats want to make corporate stock buybacks significantly more expensive. The push to raise the federal excise tax on share repurchases from 1% to 4% represents one of the party’s more aggressive moves in its ongoing campaign to redirect corporate capital away from financial engineering and toward worker investment.

The effort builds on a tax that’s barely two years old. The original 1% buyback levy was signed into law in August 2022 as part of the Inflation Reduction Act, and Democrats have been telegraphing their desire to ratchet it higher ever since.

What the proposal actually does

The legislative vehicle for the 4% rate has been the Stock Buyback Accountability Act, introduced by Senators Sherrod Brown and Ron Wyden. The bill was projected to generate $238 billion over a decade, a meaningful revenue figure that Democrats have pitched as funding for worker-focused investments and broader fiscal priorities.

The proposal has attracted support from a roster of prominent Senate Democrats, including Elizabeth Warren and Chuck Schumer.

The bigger picture on buyback taxes

On May 21, 2026, Senator Wyden joined forces with Senate Minority Leader Chuck Schumer and Senator Michael Bennet to introduce the Taxing Buybacks from Big Oil Windfalls Act. That bill targets large oil and gas companies with a dramatically steeper rate: 25% on stock buybacks.

Before 2022 there was no federal tax on buybacks at all. The 1% rate under the Inflation Reduction Act was presented as modest and sensible. Now, within a few years, proposals range from quadrupling that rate across the board to imposing a 25x increase for specific sectors.
