Welcome to the Community, @Paloma1983.

Thanks for reaching out to us. If you're referring to the new view of the Customer Contact list report, the tax status option is currently unavailable. I suggest you submit feedback directly to our Product Engineers, as they are responsible for adding features in the future.

Let me show you how:

1. Go to the Gear icon.
2. Under the Profile column, select Feedback.
3. Enter your feedback or suggestions.
4. Click Next.
5. Choose Feedback for the category.
6. Click Send.

You can also use this link to send your feedback: Customer Feedback for QuickBooks Online.

As of now, the only workaround we can do to use the tax status option is to switch to the classic view. 

Here are some articles that can help you further regarding reports:

• Customize reports in QuickBooks Online
• Run reports in QuickBooks Online

Please let me know if you have other QBO-related concerns. I'm here to lend a hand. Have a good day.
