Hi there, @Kelster.

I'm here to help you with adjusting health insurance liability in QuickBooks Online.

Currently, the Liability Adjustment tool is only available with the Desktop version. The payroll calculations in QBO are according to the setup process of your employees.

You have two options in reducing the health insurance liability without affecting the expense account:

• You can void the paychecks and recreate them. Make sure to adjust the Health Insurance calculation manually before saving them.
• You can create a Journal Entry.

I also recommend seeking an accountant for an expert's advice to ensure there will be no problem with the books in the future.

Let me know the results, Kelster. I'm still here to help you more if you have additional payroll questions. Wishing you all the best!
