Hello there, @greenfrm. I'm pleased to share facts regarding your QuickBooks Online income tax concern.
The income tax tab under taxes in QuickBooks Online (QBO) will populate information needed to file taxes based on the data you have entered into the system. QuickBooks helps you track your income and expenses and estimate your income tax based on the categories you've assigned to your transactions.
However, income tax is available under the Sole Proprietor company type. Once you have set up your account and categorized your income and expenses, you should be able to find the income tax tab in the Taxes as QuickBooks calculates income taxes based on IRS guidelines.
