Thanks for posting here, @chart,

When you void a transaction in QuickBooks the system offsets the amount on the transaction to zero out the balances. However, voiding a sales entry will not affect the sales taxes paid prior.

The system will retain the payment and apply the credit to the next taxable period. If you want to keep track of any changes to the entries in QuickBooks, you can open an Audit Trail report for it. Simply go to Reports > Accountant & Taxes > Audit Trail.

Regarding the report, you can look for Sales by Customer Detail report and customize it to only show invoices along with the taxable sales. 

1. Go to the Reports menu and choose Sales.
2. Pick Sales by Customer Detail from the list.
3. Click on Customize report at the top and head to the Display tab. From there, type Tax in the search field below Columns.
4. Mark the options for Income Subject to Tax and Sales Tax Code.
   
5. Next, go to the Filters tab and find or type Transaction Type below Choose Filter.
6. Pick the Invoices (Accounts Receivable transaction).
7. Hit OK when you're done.
