Hi, hondaspec7. I know you like to stay on top of your taxes. Let's go over certain details to clear up a few things after changing the sales tax rates in QuickBooks Online.
Keep in mind that the changes you make will update all rates except those in previous transactions and existing transactions that used the previous rate are unaffected unless you edit the transaction and specify a different sales tax rate.
Therefore, the calculation of your sales tax payable in a given period includes past transactions at the old rate. Thus, the adjustments you created are necessary to correct the amount due. You can check out this article for more information about sales tax adjustment: Create or delete a sales tax adjustment in QuickBooks Online.
I've added this link as a future reference once you're ready to file your sales tax return and record your tax payment in QuickBooks Online.
Feel free to get back to this thread if you need assistance with other tax-related concerns. I'll be here to help.
