Hey there, Aria. It's great to hear you’ve successfully implemented electronic I-9 forms for your new hires.
Regarding your question, QuickBooks doesn't currently have an option for existing employees to complete the I-9 form electronically. This feature mainly applies to new hires.
As a workaround, you can download the I-9 form and manually send it to your existing employees for them to fill out. While this may require more effort initially, it will ensure that everyone's documentation is up-to-date and compliant.
In case you need to enter your employee’s year-to-date paycheck info and company totals, check out this article for more guidance: Add pay history to QuickBooks Online Payroll.
If you have any further questions or need help with this process, feel free to reach out. Your dedication to your staff’s compliance and well-being is truly commendable, Aria. Wishing you seamless onboarding and a fantastic rest of your week!
