Hi there, marvella.
I'm here to help you in updating existing employee's W4 information.
In QuickBooks Online Payroll, you'll have the option to update existing W4 information. You can either update their W4 information with the 2019 form or use the new 2020 form. Take note that once you update their W4 information to the 2020 version, you'll no longer be able to go back to the old version.
Here's how:
- Go to the Payroll menu, and then choose Employees.
- Find or locate the employee you want to update.
- Choose Edit ✎ beside Pay.
- Click the Edit pencil icon again below the What is a W-4.
- Make any changes to the existing information, you can also update to the new W4 form.
- Once done, hit Save.
You can review this guide for your reference: What’s changing with the Federal W-4?
For more details about W4 Forms, you can visit the IRS website through this link: FAQs on the 2020 Form W-4.
You're welcome to add any details if you have further questions about W4 forms. I'll be around to help you.
