how to get a pdf file tagged

Yeah, you can find it all in the help support.

read the help support, everything is written there. Charles H taylor covers everything perfectly though...

I just did a quick search on Google and found this:

4. If the PDF is not tagged, you will need to tag it manually.

o Select Advanced > Accessibility > Add Tags to Document.
o Select Advanced > Accessibility > TouchUp Reading Order.
o Use the TouchUp Reading Order Tool to clean up the tags automatically created in the previous step.
o Verify the reading order of the elements on each page.
o Click the Show Order Panel button.
+ If necessary add alternate text to graphics or figures. (
+ Add descriptions to form fields.
+ Verify proper tagging.
o To add the needed tags, for instance, (select the heading on the page with the TouchUp Reading Order Tool, and click the Heading 1 button in the TouchUp Reading Order Panel.)
o If you were tagging an image, etc. you would select figure instead of Heading 1.

I hope this is what you need to fix your problem.

Acrobat (not Reader) can tag files. If you aren't clear how to do this
(and it can be a very slow and labour intensive task), please post in
the Acrobat Windows or Acrobat Macintosh forum.
