Custom Checkbox or Toggle With No Role or Checked State

4.1.2 — Name, Role, Value

Scenario

Setting

A government tax-filing portal

What’s wrong

Custom checkbox/toggle/radio with no role and no aria-checked (the on/off state in code) — state invisible to assistive technology.

Example

Consider a government tax-filing portal: custom checkbox/toggle/radio with no role and no aria-checked (the on/off state in code) — state invisible to assistive technology.

Why it matters

Screen-reader and voice-control users who can operate only what the accessibility tree exposes. On a government tax-filing portal specifically, they can't complete the task without extra help.

How to test

Inspect a custom checkbox/toggle/radio in DevTools: check for the correct role (checkbox/switch/radio) and a live aria-checked value — either missing fails.

How to fix

Add the proper role (checkbox/switch/radio) and a live aria-checked (the on/off state in code) state.

Outcome

Fixed, a visitor to a government tax-filing portal can complete the task without extra help.

Who is affected

Screen-reader and voice-control users who can operate only what the accessibility tree exposes.
