2026 Compliance Deadline for Government Agencies
Meet the Deadline with Automated PDF Accessibility Compliance
Section 508 PDF Compliance: Meet Federal Accessibility Requirements
What Is Section 508?
Section 508 of the Rehabilitation Act (29 U.S.C. § 794d) requires federal agencies, federal contractors, and recipients of federal funding to make all information and communication technology (ICT)- including PDF documents – accessible to people with disabilities. The Revised 508 Standards, effective January 2018, incorporate WCAG 2.0 Level A and AA success criteria for electronic documents.
PDFix automates Section 508 PDF compliance with validation, remediation, and verification – helping federal agencies meet accessibility requirements efficiently and securely.
Who Must Comply
- Federal Government
- All federal agencies – Executive, legislative, and judicial branches
- Federal departments – Cabinet-level and independent agencies
- Federal Contractors and Partners
The Federal Acquisition Regulation (FAR) Subpart 39.2 requires that acquisition of ICT supplies and services must meet applicable accessibility standards at 36 CFR Part 1194.

Section 508 vs. ADA Title II: Understanding the Difference
- Section 508 :
- Applies to federal agencies, federal contractors, and federal funding recipients
- Covers information and communication technology (ICT)
- References WCAG 2.0 Level AA
- ADA Title II :
- Applies to state and local governments (NOT federal)
- Covers all programs, services, and activities including digital content
- References WCAG 2.1 Level AA (DOJ Final Rule, April 2024
Note: If you’re a federal agency or work with federal government, you follow Section 508. If you’re a state or local government entity, you follow ADA Title II. Both require accessible PDFs but under different legal frameworks.

What Section 508 Requires for PDFs
The Revised 508 Standards specify that electronic documents must conform with WCAG 2.0 Level A and AA success criteria, including:
- Document Structure: Proper semantic tags, logical reading order, complete structure tree
- Content Accessibility: Alternative text for images, accessible form fields, document language specification, proper metadata
- Technical Requirements: PDF/UA alignment for technical structure, screen reader compatibility
