Can I extract customer list including sales tax registration information?

I can see that your business has a definite need, Irene. 

Exporting the sales tax registration numbers of each of your customers is a great suggestion that should have been available in the program. However, this option is still unavailable in QuickBooks Online.

As QuickBooks aims to help streamline workflows when managing data reports and develop straightforward tools, you may personally send this idea to our program developers to work on its progress to include them in future product updates. Here's how:

1. Go to the Gear icon and select Feedback.
2. Enter your product suggestions or feedback.
3. Then, click Next to submit feedback.
