Forms and Guides
This page provides several ways to find forms and other tax publications online. We also have a page listing reports and statistics and a Policy Documents page. Forms and publications from the IRS for federal tax filing are available at the IRS website.
We don't have blank tax forms for permit accounts on our website. That's because we print our permit forms with personal and confidential information (name, address, etc.) already included. If you don't have your form:
- File online using TAP*. It's free.
- Contact us and we'll mail you a new personalized form.
- Your authorized representative can contact us for a replacement.
