## Summary

**Clearer IRS notices for math and clerical tax errors.** This bill would require the IRS to send plain-language, itemized notices that point to the exact return line with the error, explain the adjustments, and show how to request an abatement. - Families and individual taxpayers would get notices that list the specific error, an itemized computation of adjustments that can change adjusted gross income, taxable income, deductions, credits, withheld taxes, and the refund or amount owed. Notices must include the automated transcript phone number and display the abatement deadline in bold next to the taxpayer’s address. - Tax preparers and tax professionals would see more detailed computations that name affected items and credits so they can reconcile corrected returns more easily. - IRS operations and congressional oversight would change because the IRS would have to provide abatement request procedures within 180 days, run a pilot within 18 months to send some error notices by certified or registered mail with e-signature confirmation, and report aggregated counts, dollar amounts, abatements, and pilot results to Congress.
