The main purpose of this legislation, known as the AI Tax Integrity Act of 2026, is to explore how artificial intelligence can help the Internal Revenue Service (IRS) detect tax fraud more effectively. The goal is to improve the accuracy of tax returns and reduce losses due to fraudulent activities. Key provisions of the law require the Secretary of the Treasury to set up a pilot program within six months of the law's enactment. This program will use artificial intelligence to identify incorrect tax returns.
