What is a session cookie?

A session cookie (also called per-session cookie) is a text-only string that gets entered into the memory of your browser. The value of this string is set by our Web site programs when you visit. Session cookies help us make sure that only you have access to your tax information.

We recommend that you have a printer available to print a copy of your tax return for your records.

We also recommend that JavaScript be enabled, but it is not required. The default browser settings should have JavaScript enabled.
