IRS MATH Act of 2024

The IRS MATH Act of 2024 requires the Internal Revenue Service to send clearer, more detailed notices to taxpayers when math or clerical errors are identified on their tax returns. These notices must describe the error in plain language, specify the exact line on the return where the error occurred, and include an itemized breakdown of how the error affects tax calculations - such as income, deductions, credits, or refunds. Notices must also display the deadline for requesting corrections in bold, include a phone number for automated transcript services, and avoid listing multiple potential errors. The changes apply to notices sent 12 months after enactment, and the IRS must establish procedures for taxpayers to request corrections within 180 days of the law’s passage.
