The Doug LaMalfa Federal Disaster Tax Relief Certainty Act: Technical Analysis of Statutory Revisions to Sections 165, 63, and the Inception of Section 139M
Doug LaMalfa Federal Disaster Tax Relief Certainty Act, H.R. 5366, 119th Cong. (2026) (Enrolled Bill)
For tax practitioners representing clients in disaster-impacted regions, the legislative landscape is on the precipice of a significant, taxpayer-favorable shift. As of August 19, 2026, the Doug LaMalfa Federal Disaster Tax Relief Certainty Act (H.R. 5366) has successfully passed both the House of Representatives and the Senate and is currently on the President’s desk awaiting signature. Introduced in the House on September 15, 2025, and reported with amendments by the Committee on Ways and Means on April 9, 2026 (H. Rept. 119-605), the bill passed the House under a suspension of the rules on April 27, 2026. The Senate subsequently discharged its Committee on Finance and passed the bill without amendment by Unanimous Consent on August 7, 2026.
Should this bill be signed into law by the President, it will amend the Internal Revenue Code (I.R.C.) of 1986 to “codify and extend the rules for personal casualty losses arising from major disasters and the rules for the exclusion from gross income of compensation for losses or damages resulting from certain wildfires.” For Certified Public Accountants (CPAs) and Enrolled Agents (EAs), this legislation represents a critical stabilization of disaster tax relief, transitioning temporary, ad-hoc disaster provisions into a structured statutory framework within I.R.C. § 165 and § 63, and introducing a brand-new exclusion under I.R.C. § 139M.
