Why is there suddenly no tax on my invoices in QuickBooks online?

Overview

Recently none of my transactions are calculating tax and they are coming across with tax code NT.

Environment

QuickBooks Online

Resolution

Since the release of the QBO 4.0 update the check box for TAX towards the right of each line item in your invoice is functional.

• If you'd like for that line item to be nontaxable leave the TAX box unchecked.
• If you'd like for that line item to be taxable check the TAX box in.
• This feature allows you to have taxable and nontaxable lines within the same invoice with a simple checkbox.
