When to send W-2c

They'll need both the original and the c.  Don't correct the original.

Hey there, @cmnt.

Welcome to Community. Thanks for reaching out.

As mentioned by @BigRedConsulting, you would need to prepare the W2c Form for your employee. You would also need to prepare a W3c form to accompany the W2c Form. You'd file both the W2c and W3c forms with the government.

To do this:

1. Open QuickBooks, go to Employees, then Payroll Center.
2. Once you're in the Payroll Center, click the File Forms tab.
3. Select Annual Form W2c/W3c-Corrected Wage and Tax Statement. After you select the Form, choose Create Form.
4. Next to Process W2 Select to choose all employees or a last name range.
5. Under Select Filing Period, confirm that the correct period is entered.
6. Hit OK.
7. In Select Employees for Form W2/W3, choose the employee who needs to receive a W2c then click Review/Edit.

After completing the steps above, you'll need to answer the questions on the interview page. Then you'll review each page and select Next as needed. After that, you'll fill the employee's information and include the corrected amounts.
