Need a Tax Form?

The IRS is no longer sending forms in the mail and post offices no longer carry tax forms.

Most Contra Costa County Libraries receive basic California tax forms, but no federal forms.

Library patrons can use library computers to print state and federal tax forms. If you plan to file online using a library computer, you may wish to reserve a 1 hour computer.
