Where do I find the income tax summary report

Hi there, 

QuickBooks offers a variety of reports which allow you to view your income tax summary and I'll be happy to guide you through the steps. 

At this time, QuickBooks doesn't offer the Income tax summary report but you can use the Profit and Loss report to view the info you're looking for. Here's how: 

1. Click Reports, and then type "Profit and Loss" in the Find report by name field. 
2. Change the Report period and/or click the Customize button to filter the report.
3. Click Run report.

Please refer to this article for your reference: Customize reports in QuickBooks Online.

I recommend you to also check out QBO a report called Sales Tax Liability Report that you can use and filter to get the data needed. In case you have other questions, feel free to contact our support team using this link here.
