Creating accessible PDF forms is crucial to ensuring that users of all abilities can interact with your documents effectively. Accessible PDF forms not only improve usability but also ensure compliance with standards like PDF/UA and WCAG. This guide outlines the steps to tag PDF forms for accessibility, covering everything from adding form fields to running comprehensive accessibility checks.

Steps for Tagging Accessible PDF Forms
1. Add Form Fields to the Document
Before tagging can begin, form fields must first be added to the document. Adobe Acrobat provides two main options for doing this:
- Auto-add Form Fields: Use the “Prepare Form” tool to automatically detect and add fields based on the existing content in the PDF.
- Manual Addition: Alternatively, form fields can be added manually via the same “Prepare Form” tool. This approach allows for more precise control over placement and customization of the fields.
Once the form fields are in place, tagging for accessibility can proceed.
2. Tag Form Fields Using the Tags Window
Tagging form fields ensures they are recognized by screen readers and other assistive technologies. Follow these steps:
- Find Unmarked Annotations: Use the “Find Unmarked Annotations” option from the “Tags” window’s Options panel to identify any untagged fields or objects.
- Create Object References: After identifying untagged fields, tag them with the appropriate object references to ensure they are accessible for assistive tools.
Tagging guarantees that assistive technologies can read and interact with the form correctly.
3. Set the Reading Order
Setting the correct reading order ensures a logical navigation sequence for users relying on screen readers. A clear order improves accessibility and user experience.
- Create a Parent Form Tag: Group all form fields under a parent form tag. This keeps the fields organized and ensures smooth navigation.
- Move Object References: Adjust the object references in the tags panel to reflect the desired reading sequence.
This step ensures that assistive technologies follow the form’s structure correctly when reading it aloud.
4. Add Accurate Tooltips
Tooltips provide short, descriptive guidance for users interacting with form fields. These brief instructions improve the accessibility of the form, especially for users with disabilities.
- Concise and Direct Tooltips: Ensure that each tooltip is brief but clearly describes the purpose of the form field.
- Relevant Information: For instance, a date field tooltip might read, “Enter date in MM/DD/YYYY format.”
By providing clear tooltips, users can better understand what is required for each form field.
5. Test Keyboard Navigation
To ensure full accessibility, test the form using only the keyboard. Many users rely on keyboard navigation, especially those with mobility impairments or those who prefer not to use a mouse.
- Keyboard Testing: Use the Tab key to move through the form fields, checking that the navigation flows logically and naturally.
- Enter Sample Data: Enter sample data into each field to confirm that they function correctly and accept inputs as expected.
Testing ensures that the form is user-friendly for individuals relying solely on keyboard input.
6. Apply Conditional Formatting
After ensuring that all fields are correctly tagged and the navigation works, apply conditional formatting for specific fields to enhance functionality.
- Format Date and Special Fields: Set date fields to accept the required format and apply validation for fields like phone numbers or email addresses.
- Enable Multi-line Text: Enable multi-line text input where longer responses are necessary, such as in comment fields.
- Customize Font and Color: Adjust font size, style, or color for consistency across the form.
Conditional formatting adds another layer of accessibility by ensuring the fields behave as expected when filled out.
7. Run Accessibility Checks
To verify that the form meets accessibility standards, run comprehensive checks using both built-in and external tools.
- Adobe Acrobat Accessibility Checker: Use Adobe Acrobat’s built-in accessibility checker to identify and resolve common issues like missing tags, incorrect reading order, and errors in metadata.
- PAC 2024 Compliance Tool: Run the form through PAC 2024, a tool designed to check for compliance with PDF/UA and WCAG standards.
These checks ensure that the form adheres to the required guidelines for accessibility, providing a final quality assurance step.
By following these steps—adding form fields, tagging them, setting a logical reading order, and running accessibility checks—you can create accessible PDF forms that cater to all users. This process ensures that the forms comply with accessibility standards like PDF/UA and WCAG, making them usable by individuals with diverse needs. Taking the time to ensure accessibility not only enhances user experience but also promotes inclusivity and legal compliance.
