View Results (Iowa Sales/Use Tax)
Once the file is submitted, any transactions with errors will be identified with error codes. Click on the error code to determine the cause of the error. All valid transactions will be considered filed. Transactions with errors cannot be accepted until all errors are corrected. Although a transaction may be valid, it is not necessarily accurate. The most common reasons why a transaction might not be accurate are penalty/interest not calculated accurately or not calculated at all, and prior payments for the quarter not agreeing with the amount claimed on the quarterly return.
Important: Each valid transaction will be provided with a unique 10-digit confirmation number. The confirmation numbers can be viewed and saved on the View Results screen. There will be no other acknowledgment sent.
Important: The complete file results must be saved when received if desired for future reference. There is no option to view results of previous job submissions after leaving the DWI Results screen.
