You can now set up on-line accounts with the IRS and FTB to look at your entire tax history as well as check current year information (such as estimated tax payments). You can even check the status of any payment arrangements you have made for past tax years. I have found this to be a really useful tool. Here are the links to set up online access to your tax records....

IRS (Federal) - Click Here        FTB (State of CA) - Click Here

(Access your existing FTB account Here.

 The IRS link is the same for login and setup)

It will take a couple of weeks to set up your account. The process is completed on-line, and then the IRS (and/or FTB) will send you a PIN to complete the process.
