Good day, @michelle209.
The Payroll Summary report provides key totals for income and deductions, but it doesn't show how figures like State Disability Insurance (SDI) and Personal Income Tax (PIT) are calculated.
Please know that you don't have to manually add anything to determine the final tax figures, as QuickBooks has already performed these calculations for you. To learn more about how QuickBooks calculates payroll taxes, you can check this article: Understand how your payroll taxes are calculated.
To see a detailed breakdown of your employees' taxable amount, you can generate the Payroll tax and wage summary report instead of the Payroll Summary report. This report shows wages, taxes, deductions, and contributions for a selected period. It's helpful for reviewing payroll details and ensuring accurate tax reporting.
Feel free to revisit this thread if you have any additional questions.
