How do I change the SGC rate from 9.5 to 10 percent in QBO??

Hi barry26,

Welcome to Quickbooks Community.

Super calculations should update to 10% for pay runs with Paid date starting 1 July 2021 regardless of the Period start date. As long as you have the option under Employees > Payroll Settings > Details > Automatically update super rates selected it will automatically update every time a change is made to the super rate.

Feel free to reach out to us if you have questions.
