Hi, I work in a different state from my wife and we need to e-file a joint tax return. Is there a form like 8867 to get a PIN from her to me to e-file from my computer?

If you are using the TurboTax software to complete and file your tax return, the return is self-prepared.  All you need is her permission to file the tax return as Married Filing Jointly.

The e-file PIN can be any self-selected 5 digit number you select for yourself and for your spouse.

To efile you need your 2022 AGI.  The AGI is on 2022 1040 or 1040SR line 11. If you filed a Joint return you use the same AGI for each spouse.

How to find the AGI.

If you didn't file 2022 or filed it later in the year or mailed it, then try entering 0 for the AGI. If that doesn't work you will have to print and mail your return.
