Recalculate sales tax on the affected transactions

If you have affected transactions between August 8 and August 10, 2021, you may elect to rerun the transactions.

  1. In AvaTax, select the Transactions tab.
  2. To locate the transactions impacted:
    • Select a date range From 08/08/2021 To 08/10/2021.
    • Select Document status: Committed.
    • Select Country: United States of America.
    • Select Region: Maryland.
  3. Select the the transactions to recalculate, or select all filtered transactions by selecting the top check box. NOTE: Keep in mind that locked transactions can't be recalculated; any transactions included in filed returns must be credited and rebilled.
  4. Select Recalculate, then select Yes, Recalculate.
  5. When recalculation completes, select OK.

Note: If you choose not to recalculate tax due and report the tax charged and collected as is, you risk an unfavorable audit and additional tax assessment, plus potential penalties and interest in the future.

If needed, contact your tax professional for guidance on how to report the undercharged tax.
