I can guide you where you can see how QuickBooks calculates sales taxes on your progress invoice in QuickBooks Online (QBO), Matt.
Before proceeding, please know how QuickBooks calculates sales taxes:
Since the sales tax calculation is incorrect, we can use the See the Math option to determine how QBO comes up with the specific amount. It will also allow you to edit the sales tax on the invoice page.
I've attached screenshots for reference:
In the meantime, let's check your sales tax category and rate for your item setup in the Products and Services section, which also affects sales tax calculation:
- Go to the Settings icon at the top right corner of your QBO page.
- Click on Products and Services.
- Select the specific item and click on Edit.
- In the Sales Tax section, select Edit Sales Tax.
However, if you've set up the address and product category correctly based on how QuickBooks calculates taxes but still have incorrect sales tax calculations, I suggest performing browser troubleshooting.
If the issue persists, it's best to contact our Support Team to assist you further. They have the required tools to identify the cause of the problem by initiating a screen-sharing session.
Here's how to reach out to them:
