When QuickBooks updated your sales tax center to automated sales tax, all your tax rates will be gone. This is because QuickBooks will automatically do the sales tax calculations for you on your invoices and receipts for easy and accurate filings.
However, if you want to add sales tax rates, you can do it so. Here's how:
Click Taxes from the left menu, then select Sales Tax.
Select Sales tax setting at the top-right corner.
Hit the Add rate button to create your own sales tax rates.
Enter the Name, Agency, and Rate of your sales tax, then click Save.
