Section 508 of the Rehabilitation Act

What is Section 508?

Section 508 of the Rehabilitation Act is a U.S. federal accessibility law, codified at 29 U.S.C. § 794d, that requires federal agencies to ensure their information and communication technology (ICT) is accessible to employees and members of the public with disabilities. Originally added to the Rehabilitation Act of 1973 in 1986 and significantly amended by Congress on August 7, 1998, the law was further strengthened by the U.S. Access Board's January 2017 final rule, which updated the technical standards and incorporated WCAG 2.0 Level A and AA success criteria by reference (36 CFR Part 1194), with agency compliance required from January 18, 2018. Covered ICT includes websites, web applications, software, electronic documents, hardware, telecommunications equipment, public-use kiosks, and any digital product developed, procured, maintained, or used by a federal agency. The GSA's Government-wide IT Accessibility Program administers implementation guidance through Section508.gov and submits annual compliance assessments to Congress under the Consolidated Appropriations Act of 2023 (Section 752); the DOJ Civil Rights Division submits separate biennial compliance reports to the President and Congress and can bring enforcement actions.

Who must comply?

Section 508 applies directly to every U.S. federal executive branch department and agency - including the U.S. Postal Service - whenever they develop, procure, maintain, or use ICT. Private-sector vendors and contractors must also comply: any company selling software, hardware, websites, electronic documents, or other digital products or services to the federal government must demonstrate that its offerings meet the Revised 508 Standards, typically through a completed Voluntary Product Accessibility Template (VPAT) / Accessibility Conformance Report (ACR). Organizations that receive federal grants or funding - including state and local agencies, universities, nonprofits, and hospitals - may be subject to Section 508 obligations depending on the terms of their funding agreements. Coverage extends to employee-facing internal systems, not just public-facing websites, making it one of the broadest ICT accessibility requirements in the world.

Key requirements

• Web content and electronic documents must conform to WCAG 2.0 Level A and Level AA success criteria (36 CFR Part 1194, Appendix A). Agencies and vendors targeting WCAG 2.1 AA satisfy and exceed this mandatory floor.
• Software applications, including non-web software, must meet the functional performance criteria and applicable technical standards in the Revised 508 Standards (36 CFR Part 1194, Appendix C).
• Hardware ICT - computers, multifunction printers, telecommunications equipment, and public-use kiosks - must meet hardware-specific accessibility requirements including operable controls and support for assistive technology.
• Agencies must provide equivalent access to employees and members of the public with disabilities when an undue burden or fundamental alteration exception is claimed, and must document that determination in writing.
• Federal procurement requires agencies to identify applicable Section 508 standards before solicitation, include 508 requirements in contracts, and evaluate vendor VPATs/ACRs prior to award.
• Electronic documents (PDFs, Word files, spreadsheets, presentations) disseminated by agencies or provided under contract must conform to WCAG 2.0 Level AA and, where applicable, PDF/UA standards.
• Agencies must maintain a formal Section 508 complaint process and designate a Section 508 Program Manager responsible for training, reporting, and ongoing conformance.

Key dates & deadlines

• June 21, 2001Original Section 508 standards (promulgated December 21, 2000) became enforceable for federal agencies.
• January 18, 2018Revised ICT Standards (incorporating WCAG 2.0 Level A and AA) became mandatory for all new federal ICT development, procurement, maintenance, and use.
• Ongoing (annual)GSA must submit a governmentwide Section 508 compliance assessment to Congress annually under the Consolidated Appropriations Act of 2023 (Section 752); the DOJ submits a separate biennial report to the President and Congress on agency compliance.

Penalties & enforcement

Individuals with disabilities who are denied accessible ICT by a federal agency may file an administrative complaint directly with that agency, and - after exhausting administrative remedies - may bring a civil lawsuit in federal court. Available remedies mirror those under Section 504 of the Rehabilitation Act and include declaratory relief, injunctive relief (requiring the agency to remediate), and attorneys' fees; however, compensatory and punitive damages are generally not recoverable against federal agencies. For vendors and contractors, non-compliance can result in contract termination for cause, reprocurement costs charged back to the vendor, exclusion from future federal procurement opportunities, and referral for suspension or debarment. Federal agencies themselves face congressional oversight through annual GSA and biennial DOJ compliance reports, DOJ enforcement actions, and reputational damage; recent DOJ enforcement settlements have required agencies to undertake multi-year remediation programs at significant cost.

How Section 508 relates to WCAG

The Revised 508 Standards, effective January 18, 2018, formally incorporate WCAG 2.0 Level A and Level AA success criteria by reference for all web content and electronic documents covered by Section 508 (36 CFR Part 1194, Appendix A). As of mid-2026, WCAG 2.1 and WCAG 2.2 have not been formally adopted into the binding regulatory text of Section 508 - any update to incorporate newer WCAG versions would require new rulemaking by the U.S. Access Board. However, the Access Board and GSA actively encourage agencies to adopt WCAG 2.1 AA and WCAG 2.2 AA as best practice, and Section508.gov has published guidance on the additional requirements those versions introduce. In practice, agencies and vendors that target WCAG 2.1 Level AA conformance - the widely adopted international baseline - satisfy and exceed the current mandatory Section 508 web content standard.

How EqualWeb helps you meet Section 508

EqualWeb's AI Accessibility Widget - deployed with a single line of code - automatically remediates approximately 80% of common WCAG 2.0 and WCAG 2.1 Level AA issues in real time on the client side, giving federal contractors, vendors, and funded organizations a meaningful head-start toward Section 508 web content conformance. The widget alone does not produce full conformance; it is one layer of a broader compliance program. For agencies and vendors that need full, documented conformance, EqualWeb's Managed Compliance service pairs certified IAAP/CPWA accessibility experts with ongoing client-side remediation, continuous monitoring, and a signed Accessibility Compliance Certificate alongside a completed VPAT/Accessibility Conformance Report - the precise documentation federal procurement requires. EqualWeb's PDF Tools address one of the most commonly cited Section 508 gaps: inaccessible electronic documents. They check and remediate PDFs to both PDF/UA and Section 508 standards so agencies can confidently distribute accessible content. The Continuous Monitoring dashboard tracks a live 0-100 compliance score with regression alerts, enabling program managers to demonstrate ongoing conformance and respond quickly to accessibility regressions before they trigger complaints. Together, the widget, managed expert service, and monitoring tools support a layered Section 508 compliance program - working toward full conformance rather than relying on any single automated fix.
