My quickbooks account is using my name associated with my tax return. I file a joint return, and my wife is the one with the Self employed business. How can I add her?

Nice to have you here in the Community space, @ttkcwilson.

I can guide you how to add your wife in filing a joint return. You can go to the Gear icon and add your wife's tax details from there. Let me show you how to do it in your QuickBooks Self-Employed (QBSE).

Here’s how:

1. Go to the Gear icon.
2. Select Tax profile.
3. Under Tax profile, enter your Spouse's first name, last name, annual W2 income, and federal withholding.
4. Proceed with the Deduction and other required information.
5. Click Save.
