In LumaTax: 

  1. Navigate to the Client Dashboard for this client by selecting them from the drop down in the upper left. 
  2. Go to the card for Data and click the Upload Data button.  Note: You will not be able to upload the data until the client's profile is completed. 
  3. Click Continue. Locate and select the file on your computer. 
  4. If the file automatically maps (Amazon or Shopify), you will see a logo for the source system. If not, you'll be prompted to map your file's headers to the appropriate fields in LumaTax and validate the mapping. When finished, click Continue. 
  5. Review the valid and invalid rows and download your validation report. 
  6. When ready, upload additional files or return to the Client Dashboard to run a Nexus Analysis Report.
