I have an SCorp and just finished adding my data for 2019. I need to close the books and file the SCorp returns. What is the best tax program that integrates with QBO?

There is no tax package that integrates with QBO

Hello there, @dchapp2001.

To check out what third-party apps integrate with QuickBooks Online, click here. You can see the Key benefits, Pricing, and Reviews for each app by clicking on their tile. If you're logged into your account, then you can navigate to the Apps tab on the left-hand menu to see what apps are available for integration.

Let me know if you have further questions. I'm just a Reply away.
