The Internal Revenue Service Math and Taxpayer Help Act has advanced to the White House after passage in the Senate.

The bill, H.R. 998, was introduced in the House in February 2025 and requires the IRS to provide specific information when it sends a notice to taxpayers when there is a math or clerical error and send a notice related to an abatement of taxes assessed due to a math or clerical error, as well as provide procedures for requesting such an abatement.

It also requires the agency to implement a pilot program for sending notices on a clerical error.

The notice regarding the error must include the following information:

• A clear description of the error, including the type of error and the line in the tax return where the error occurred;
• An itemized computation of adjustments required to correct the error;
• The telephone number for the automated transcript service; and
• The deadline for requesting an abatement of any tax assessed due to the error.

IRS will be required to provide procedures to taxpayers how to request in writing, electronically, by phone, or in person an abatement of tax assessed due to a math or clerical error. The pilot program on the issuance of the math/clerical error letters will require a report to Congress.

H.R. 998 passed by unanimous consent in the Senate on October 20, 2025. It passed by a voice vote in the House of Representatives on March 31, 2025.

The American Institute of CPAs applauded passage of H.R. 998.

“The IRS Math and Taxpayer Health Act represents common-sense reform that enhances IRS operations and improves the taxpayer experience,” AICPA Vice President of Tax Policy and Advocacy Melanie Lauridsen said in a statement. “This new law directly addresses long-standing issues with how the IRS communicates and resolves mathematical or clerical errors on tax returns. By expanding access to abatement procedures and establishing a pilot program for better communication, this law provides greater fairness and due process, reduces confusion and stress and offers taxpayers improved access to remedies.”
