Table of Contents
The Inflation Reduction Act of 2022 is a landmark United States federal law enacted on August 16, 2022, primarily focused on reducing healthcare costs, addressing climate change, adn increasing tax revenue.
Signed into law by President Joe Biden, the Act represents a significant investment in clean energy and climate resilience, aiming to lower carbon emissions by roughly 40% by 2030. It achieves these goals through a combination of tax credits, rebates, and grant programs. Beyond climate provisions, the law allows Medicare to negotiate prescription drug prices, lowering costs for seniors, and extends Affordable Care Act subsidies.
For example, the Act provides a tax credit of up to $7,500 for the purchase of new electric vehicles and $4,000 for used electric vehicles, incentivizing consumers to adopt cleaner transportation options. IRS Clean Vehicle Credits
Key Provisions & Climate Change
The Inflation Reduction Act allocates approximately $369 billion towards climate and energy programs, making it the largest climate investment in U.S. history.
These investments include tax credits for renewable energy production, such as solar and wind power, as well as incentives for energy efficiency improvements in homes and businesses. the law also establishes programs to support the advancement of clean energy technologies,like carbon capture and storage. A significant portion of the funding is directed towards environmental justice initiatives, aiming to address the disproportionate environmental burdens faced by disadvantaged communities.
Specifically, the Act includes $60 billion for environmental justice initiatives, as outlined in the EPA’s Inflation Reduction Act webpage, demonstrating a commitment to equitable climate solutions.
Healthcare Cost Reduction
A central component of the Inflation Reduction act is its effort to lower healthcare costs,notably prescription drug prices.
The law empowers Medicare to negotiate the prices of certain high-cost prescription drugs, a change that had been sought by Democrats for decades. These negotiations are expected to begin in 2026, with the first negotiated prices taking effect in 2027. The Act also extends enhanced premium tax credits for health insurance purchased through the Affordable Care Act marketplaces, preventing millions of Americans from losing coverage.
The Congressional Budget Office (CBO) estimated that allowing Medicare to negotiate drug prices will save the federal government approximately $101.8 billion over ten years.
Tax Provisions & Revenue Generation
The Inflation Reduction Act aims to raise revenue through various tax provisions, primarily targeting large corporations.
A key provision is a 15% minimum tax on corporations with profits exceeding $1 billion, designed to ensure that profitable companies pay a fair share of taxes. The law also increases funding for the Internal Revenue Service (IRS) to improve tax enforcement and reduce tax evasion. These revenue increases are intended to offset the costs of the Act’s climate and healthcare provisions, contributing to deficit reduction.
The Joint Commitee on taxation projected that the corporate minimum tax would generate approximately $220 billion in revenue over ten years.
Legal Challenges and Current Status (as of January 25, 2026)
Following its enactment, the Inflation Reduction Act faced several legal challenges, primarily focused on the constitutionality of its corporate minimum tax and the method by which Medicare negotiates drug prices.
As of January 25, 2026, the Supreme Court upheld the corporate minimum tax in a 6-3 decision on June 20, 2025 (Amarin Pharma, Inc. v. Yellen, 598 U.S. ___ (2025)). Challenges to the Medicare drug price negotiation provisions have also been largely unsuccessful, with courts consistently ruling in favor of the government. Implementation of the Act’s provisions is ongoing, with significant progress made in deploying clean energy tax credits and initiating the Medicare drug price negotiation process.
