I am wondering what is the best software to purchase that is compatible with Quickbooks online and CRA certified to submit corporate tax return? Thank you.

We're unable to provide a specific third-party app that is compatible with QuickBooks Online (QBO) and CRA certified to submit corporate tax return, p-seu-dio. However, there are several third-party apps that you can integrate. Let me guide you to where you can find them.

1. Go to the QuickBooks Online App Store.
2. If you don't know what specific app you're looking for, go to the search bar and type in the keyword or the transaction you're going to do for your business.
3. Then click on the magnifying glass icon to search and browse for any suggested apps.

If you want to learn more about the app, including contact details and support information, you can click on the app that provides services that are relevant to your business. Any questions about the integrated app in your Online account should be directed to the app's third-party provider.

Also, if you need to view your sales tax info anytime, you can run the Taxable Sales Summary report. Here's an article for details: Check how much sales tax you owe in QuickBooks Online.
