Where they stand
On the recordThe cited public record shows support for closing corporate tax loopholes and reducing offshore-tax incentives, a high-income tax floor including capital gains and dividends, and reforms addressing concentrated billionaire political power. It also contains a mixed statement about stock buybacks that does not establish support for taxing them.
Position details
Make large corporations pay more tax
SupportsIn 2018, Tammy Duckworth supported closing corporate tax loopholes that incentivize offshoring and said corporations should pay their fair share.
This evidence concerns corporate tax loopholes and offshoring incentives, not annual wealth taxes or individual wealth taxation.
Tax buybacks and excessive CEO pay
Mixed record onIn 2022, Tammy Duckworth’s cited statement identified profit maximization and stock buybacks as reasons oil companies were not increasing production, without endorsing taxes on buybacks or excessive CEO pay.
The statement concerned oil-company production and pricing behavior during an energy crisis and does not establish a general tax position on buybacks or executive compensation.
Limit billionaire political power, not just raise revenue
SupportsTammy Duckworth has supported reforms addressing concentrated billionaire political power, including removing big money from politics and strengthening anti-corruption laws.
Her 2021 statement addressed money in politics and anti-corruption reform, while her 2025 remarks addressed concentrated billionaire power and accountability; the evidence does not specify a tax, campaign-finance, or antitrust mechanism.

Tax capital gains and loopholes instead of wealth itself

This does not establish support for an annual tax on net worth or unrealized gains.
