Me and my wife filling the 1040 EZ jointly.
I signed and put date on May 25th.
She signed the form on June 20th and put that date.
Is it okay if the date are not same in the 1040EZ form.
Recording the real dates for signatures should be fine. The main dates to be concerned about are the dates for mailing/filing and the dates that your payments are made because those affect possible penalties and interest.
