I would like to elaborate just a bit on Paul’s reply. If you register with SST states and engage Avalara as your Certified Service Provider (CSP) for those states and qualify for “Volunteer” status in those states, then the entity/use codes on the shipment invoices pertaining to those states are not only ignored by AvaTax, but also technically are not allowed, per the Streamlined Sales and Use Tax Agreement. Customers’ exemptions cannot be passed on the invoice level; to properly exempt the customers from tax, relevant customer information must be entered in AvaTax via the Exemptions tab or in Avalara Exemption Certificate Management. Entering that information is more time-consuming, but the payback in the forms of free processing and audit protection is a worthwhile tradeoff!
