Manage Taxability of Products and Services

Apply tax codes to manage item taxability. Assigning product and product categories to items gives you important jurisdictional subtlety in taxability. Avalara has predefined Avalara tax codes with a taxability profile in place for all US states. Or, create your own custom tax codes and tax rulesHoverTT.png in AvaTax. Keep in mind that Avalara updates Avalara tax codes when taxability rules change, but custom tax codes and rules are maintained by you; they're not updated when tax laws change. Also, make sure you enable nexus in the jurisdictions where you're required to register and collect tax so AvaTax calculates the full tax amount.

Map items to tax codes

  • A tax code is a unique code for similar products, services, or charges that tells AvaTax what kind of sales tax, if any, to charge for them. 
  • It's a best practice to map items to tax codes in your accounting software. Find your integration to learn how to map tax codes in your accounting software.
  • If you can't pass a tax code from the item management screen, or if you need a remotely-hosted mapping system to accommodate multiple integrations, map the items to tax codes in AvaTax.
  • If you map in your accounting software and AvaTax, the AvaTax mapping supersedes any mapping in your accounting software.

Map item to UPC

For an item, you can choose to send the model number or the UPC (Universal Product Code) from your accounting software to AvaTax. If the UPC isn't available, the model number is set as the default and sent to AvaTax.

To customize taxability for specific products, tax codesHoverTT.png need to be mapped to UPCs, and model numbers. Items that aren't mapped to tax codes are treated as Tangible Personal Property (TPP), and are fully taxed during calculation. 

  1. Log in to Microsoft Dynamics NAV.
  2. Go to Departments > AvaTax > Setup > AvaTax Configuration > Tax Calculation tab and ensure that the Use UPC as Item Code option is enabled. If this option is enabled, the UPC is sent to AvaTax if it is defined for an item. If this option is disabled, even if the UPC code is defined for a item, the item code is sent to AvaTax. 
  3. To map an UPC to an item, follow these steps:
    1. Go to Departments > AvaTax > Utilities > Item UPC Code Mapping to map the UPC to an item.
    2. On the Item UPC Code Mapping page, type the required information to map the UPC to an item.
