- Scenario
- Fixing PDF document accessibility compliance to ensure interactive form fields pass the accessibility checker for screen readers.
- Observed behavior
- The accessibility checker continues to report errors for tagged form fields even after following standard online correction instructions.
Before making structural changes to your tags tree, save a backup copy of your PDF document to prevent accidental loss of form data or existing correct tags.
Verify and Correct Form Tags and Tooltips Manually
Manually inspect the Tags panel to ensure each form field has a proper Form tag and an accessible name (tooltip) for screen readers.
Often, form fields fail accessibility checks because they lack a designated Form tag, have a blank tooltip, or are placed outside the logical reading order of the document.
Navigate to the accessibility or tags pane in your PDF editor (usually found in the left navigation pane) to view the document's tag tree.
Expand the tags tree and ensure that every interactive form field has a corresponding '<Form>' tag structurally placed next to its visual text label.
Right-click the problematic form field on the page, select Properties, navigate to the General tab, and ensure the 'Tooltip' field contains a clear, descriptive label.
Look for empty or duplicate tags in the Tags panel that do not highlight any visible content on the page, right-click them, and select Delete.
Re-tag Form Fields using the Reading Order Tool
Clear out corrupted tags and use the structural reading order tool to freshly tag the problematic form fields.

Frequently Asked Questions
Why does my PDF form field fail the accessibility check?
Form fields usually fail accessibility checks if they lack a descriptive tooltip (accessible name), are not nested inside a proper '<Form>' tag, or if the tags are out of logical reading order.
What is an accessible name in a PDF form?
An accessible name is a text description, often set in the field's Tooltip property, that screen readers announce to visually impaired users so they understand what information to enter into the field.
Can I automate the fixing of tagged PDF form fields?
While some accessibility tools offer an 'Autotag Document' feature, interactive form fields almost always require manual verification to ensure the tooltips and logical reading order accurately reflect the visual layout of the form.
