Thanks for taking the time to reach out to us. I'm here to help and provide some insights about sick time in QuickBooks Online (QBO).
Are you trying to separate the accrual and regular sick pay for your employee? If so, this option isn't available in QuickBooks. The Sick/Vacation accruals in QBO normally resets every year. However, you have the option to add last year's accruals into the current year by manually adding the numbers to the employee's current sick/vacation hours.
