How do I change an email of an existing contractor?

Welcome to the Community, @jennsuprgrl

Definitely, I can provide the steps on how to change the email of an existing contractor in QuickBooks Online (QBO).

To update your contractor's email let's go through the Expense page. Just a heads up, updating the email address of your contractor will be automatically reflected in the Contractor tab. Here's a more detailed step:

1. Go to Expenses from the left menu, then choose Vendors.
2. Locate the contractor from there and open the profile.
3. Select Edit.
4. Edit the new email address.
5. Select Save and close.
6. Once done, refresh QuickBooks for changes to take effect.

Moreover, if you want contractors to add their tax information, you can invite them to QuickBooks Online or if you want to get a closer look at your business's finances, you can check out this material to learn how to run, print, and customize payroll reports in QuickBooks Online Payroll.
