Thanks for sharing your query here with us, mdacimo. Let me provide insight to help you manage tax liability reports on your sales transactions.

In QuickBooks Online, sales tax liability reports summarize the taxable and non-taxable sales tax you've collected and owe to tax agencies. If these items are showing as Taxable on the report after a certain date, you'll want to ensure that no sales tax is applied to your transactions.

With this, you can select and review the amount of that item on the report and modify it as Non-Taxable. To help you with the process, refer to the steps below:

1. In your Sales Tax Liability Report, find the item showing in Taxable Sales.
2. Click on the amount to view the Transaction Report.
3. Select the specific transaction, then uncheck the Tax box column of that line item in that entry. 
4. Review all information and click Save and Close. 

In addition to that, you may consider reviewing each of your items to verify and check if there are changes made to these data. To do this:

1. Go to Sales and select Products & services.
2. Find the specific item and click Edit.
3. Under the Sales tax section, press Edit sales tax
4. Review the details, then Done.
