How to Fix Tagged Annotations Failed for PDF Footnote References
Question details
The user needs to resolve an accessibility check failure related to PDF footnote reference tagging.

- Product
- Device & OS
- not provided
- Scenario
- Running an accessibility check on a PDF document containing footnotes, which results in a tagging error.
- Observed behavior
- The accessibility checker reports 'Tagged Annotations Failed' for footnote references, even though the content panel shows references in a Reference container and footnotes in a Note container.
Ensure you are using an advanced PDF editor with accessibility and tag-editing capabilities, as standard PDF readers do not allow modifications to the document's hidden tag structure.
Repair PDF Tag Structure Manually
Use the built-in Tags panel to properly associate the footnote reference with its corresponding note and ensure proper alternative descriptions.
Even if the Content panel looks correct, screen readers depend entirely on the document's Tag tree. A visible footnote link must possess a valid structure tag to pass the accessibility check.
Navigate to the accessibility or advanced editing tools in your PDF software and open the 'Tags' pane from the navigation pane on the left.
Expand the tag tree and locate the specific <Reference> tag that is causing the error. You can often right-click the error in the accessibility checker and select 'Show in Tags Panel'.
Ensure that the footnote reference (the superscript number) is nested properly within the <Reference> tag, and that the link annotation has a corresponding object reference tag (OBJR).
Right-click the <Reference> tag, select 'Properties', and add a descriptive tooltip or alternate text (e.g., 'Go to Footnote 1') so screen readers can interpret the link correctly.
Once the tags are properly associated and alternate text is applied, run the Accessibility Check again to confirm the 'Tagged Annotations Failed' error is resolved.

Correct Tagging in the Source Application
Fix the formatting in the original source document (such as Word) and re-export the PDF to generate a clean, automated tag tree.
Generate Properly Tagged PDFs Directly with WPS Office
Avoid complex PDF tagging errors by creating perfectly structured documents from the start. WPS Office automatically generates standard accessibility tags when exporting your Word documents to PDF.
- 1. Open Your Document: Launch WPS Writer and open the document containing your footnotes and references.
- 2. Format with Built-in Tools: Navigate to the 'References' tab to insert footnotes. Using native tools ensures the software recognizes the structural relationship.
- 3. Export to PDF: Click 'Menu', select 'Export to PDF', and ensure your settings are configured to retain document structure. Click 'Export' to generate an error-free file.

Frequently Asked Questions
What causes the 'Tagged Annotations Failed' error in a PDF?
This error occurs when a link, footnote reference, or annotation lacks a proper structure tag (like an OBJR tag) or alternate description in the PDF's hidden tag tree, preventing screen readers from understanding it.
Can I fix PDF tagging errors with a basic PDF reader?
No. Basic PDF readers only display the visual content. To fix structural tagging errors, you need advanced PDF editing software that provides access to the document's underlying Tags panel and Reading Order tools.
Why do my footnotes look fine on the page but fail the accessibility check?
The visual layout is separate from the document's logical structure. Even if a footnote visually appears at the bottom of the page, the accessibility checker looks at the hidden tags to verify that the inline reference is properly linked to the note text for assistive technologies.
