How can I get my 5 digit signature ID and my husband's? I don't know what it was last year?

The Signature ID is any 5-digits of your choice.  It is on a screen with today's date and your birthdate.

Your 5 digit signature ID on the Consent to Disclosure screen (also called a Self-Select PIN) is how you sign your federal return if you're e-filing. It's the electronic equivalent of manually signing a paper return.

If the field is blank, just enter any 5-digit number. You can re-use your IRS e-filing PIN or make up a totally different number. Same goes for your spouse if you're filing jointly.
