Summary
A 25% wealth tax is a proposed tax on an entity's net worth, encompassing assets like cash, real estate, financial securities, and accrued capital gains, while typically excluding liabilities such as mortgages. This specific proposal, sometimes referred to as an unrealized gains tax, is supported by figures like Kamala Harris and Joe Biden and has been discussed in the context of the 2024 US Presidential Election. Proponents argue it can reduce income inequality, while critics contend it could negatively impact the economy, potentially leading to long-run GDP declines of 2% to 5%, hundreds of thousands of job losses, and a reduction in other tax revenues that could outweigh the wealth tax's yield. Concerns have been raised about its impact on founders, including significant liquidity challenges and the possibility of capital flight, drawing parallels to historical examples in France. The proposal is also situated within broader discussions about economic and political ideologies, including the increasing acceptance of socialism and shifts towards populism, challenging the principles of a free market economy and creating a complex compliance landscape for the IRS. Historically, the number of OECD countries with a personal wealth tax has decreased from 12 in 1990 to 5 in 2017, reflecting ongoing debates about its efficacy and implementation challenges, including potential unconstitutionality in the US and issues of double taxation.

A wealth tax (also called a capital tax or equity tax) is a tax on an entity's holdings of assets or an entity's net worth. This includes the total value of personal assets, including cash, bank deposits, real estate, assets in insurance and pension plans, ownership of unincorporated businesses, financial securities, and personal trusts (a one-off levy on wealth is a capital levy). Typically, wealth taxation often involves the exclusion of an individual's liabilities, such as mortgages and other debts, from their total assets. Accordingly, this type of taxation is frequently denoted as a net wealth tax. As of 2017, five of the 36 OECD countries had a personal wealth tax (down from 12 in 1990). Proponents often argue that wealth taxes can reduce income inequality by making it harder for individuals to accumulate large amounts of wealth. Many critics of wealth taxes claim that wealth taxes can have a negative economic effect, with economic models showing long-run GDP declines of 2% to 5%, the loss of hundreds of thousands of jobs and a loss in other tax revenue which exceeds the revenue from the wealth tax.
