Information on this website is provided for your convenience in our effort to give you the best customer service possible. While we strive for accuracy, laws and procedures change over time. Therefore, if you are relying on information from this site, we recommend that you contact us first to see if it is still valid.
Our goal is to make this website accessible to all our visitors and to comply with the Americans with Disabilities Act of 1990.

The Idaho State Tax Commission publishes our forms, publications, reports, and other documents as PDF files. These can be opened, read, and printed using the free Adobe Reader program which you can download to your Windows, Mac, or Linux computer. Clicking on the link will cause the PDF to either appear in your web browser* window or download to your computer desktop, depending upon how you have your computer configured.
To view our PDF documents, visit the Adobe site's Adobe Reader page and download and install the software.
Some forms (especially income tax forms) have been designed to let you fill in the fields using your computer. Forms with this option are identified by an F following the publication date in their listing (e.g., current individual income tax forms).
Click in the first field of a fill-in form and begin typing. You can tab between fields. Use your mouse to "check" any appropriate boxes. After filling in your form, print one copy for yourself and one copy to mail to the Tax Commission.
To keep your personal information secure, we don't allow fill-in forms to be saved. When these forms are saved on a public computer, for example, your information can be seen by the next user if your browser isn't closed properly at the end of your session.
In addition to fill-in forms, we provide access to vendors that provide free electronic filing for qualified taxpayers. This information is available on our E-file for free page. (Be sure to use the links on that page to use the free services offered.)
If you have questions, please use our Website Feedback form and include your email address.
If you have problems using fillable forms in Windows 10 using the Edge browser, follow these instructions:
- Click on the link to the PDF form.
- Look in the upper left and click on the three horizontal dots (see image below).
- Choose "Open with Internet Explorer" from the menu.
- The form will display the highlighted fields for you to edit.
Note: You must have a copy of Adobe Reader on your PC.
