If this is the first year you are using Zenefits for the ACA filing and you are still in the setup steps, click “Restart Setup” in the upper-right hand corner to go back and make this adjustment. The Safe Harbor selection is in Section 1 of the setup flow.
If this is the first year you are using Zenefits for the ACA filing and you are on the Overview page, please reach out to our Support team. We are able to update your Safe Harbor on our side.
If you have used the ACA Compliance app in previous years, click on the Settings tab in the top navigation on the ACA Overview page. You will come to a page titled 'Plan Affordability' and can update the Safe Harbor selection from here. Much of the information you've already provided will remain in the tool, however, you may need to provide additional compensation data, if needed.
