Hi, MasterJoe. I appreciate your effort in reaching out to our live support team multiple times. However, you cannot adjust an automated sales tax rate, as the system calculates sales tax for each transaction automatically. I'll explain how this auto-calculation works.
QuickBooks Online automatically calculates the total sales tax rate based on your customer's sales tax-exempt status, the location of the sale or shipment, and the sales tax category of your product or service. The total sales tax rate consists of the combined state and local rates, which may include city, county, and district rates.
For more information, please refer to this article: Set up and use automated sales tax in QuickBooks Online.
Since the automated calculation is incorrect, you can set up a custom tax rate and use it for your sales forms. Here's how:
- Navigate to the Taxes menu, then select Sales tax.
- Click on Tax settings.

- Beside Turn off sales tax, click the drop-down menu and choose Add custom rate
- Choose either Single or Combined.
- Fill in the Name of the custom rate. For a combined rate, enter a Nickname for each rate you need to combine as one custom rate.
- Select the Agency you file payments to. For a combined rate, select the agency for each rate you need to group as one custom rate.
- Enter the Rate, then Save.

Additionally, you can file your sales tax return and record sales tax payments to ensure accurate tracking and compliance.
