Post-Disaster Assistance Online Accountability Act

Creates a public subpage on the federal spending transparency website to show federal disaster assistance and requires covered federal agencies to publish quarterly, machine‑readable data on disaster assistance amounts and detailed project‑level information. OMB will lead the effort with Treasury and covered agencies and may hire a private contractor to build the subpage if needed.

Defines which agencies and programs are covered, what counts as disaster assistance, who qualifies as eligible recipients, and which natural disasters are included, citing authorities such as Stafford Act programs, certain Small Business Administration loan programs, HUD authorities, and the National Flood Insurance Program.
