Who You Exempt

This article applies to:Connector for Microsoft Dynamics NAV

An exemption certificate number identifies a buyer as exempt. If you regularly sell to tax-exempt customers, you need to consistently exempt their purchases. You also need copies of all of your customers' exemption certificates in case of an audit. There's more than one way to do both:

  • If you already have a method to store exemption certificates, send customers' exemption certificate numbers to AvaTax using your business application, or send entity/use codes that explain why the customer should be exempt.
  • If you don't already have a way to store certificates, use Exemptions or CertCapture, depending on your needs:
    • To exempt buyers and store their exemption certificates, use Exemptions.
    • To exempt customers, and to request, generate, and store exemption certificates, use CertCapture.

You can exempt customers, but that doesn't mean you're compliant. You need valid documentation of your buyer's exemption certificate to support tax exemptions in case of an audit. Valid documentation includes copies of valid exemption certificates and the associated invoices. If you exempt customers from tax with exemption numbers or entity/use codes, keep organized records for all exempt purchases.

Use CertCapture

CertCapture manages exemption certificates and other compliance documents. Use it with or without AvaTax. Use CertCapture to:

CertCapture stores exemption information and official copies of exemption certificates for each customer. With CertCapture, you always have an organized, audit-ready database of exemption certificates.

If you're not using CertCapture to manage exemption certificates, contact your Account Manager for more information.

Use AvaTax Exemptions

Use exemption certificate numbers or entity/use codes

An exemption certificate number identifies a buyer as exempt. To exempt a customer, enter the buyer's exemption number on the invoice when making a sale.

AvaTax uses an entity/use code to exempt a customer from tax. An entity/use code works in two ways:

  • The code flags a transaction with a reason for the exemption based on the entity that's buying
  • The code flags a transaction based on how the buyer uses what they purchase

Entity/use codes are applied based on government laws. Use your accounting software to assign entity/use codes to your transactions.

Exempt customers from sales tax with an exemption certificate number

  1. In Microsoft Dynamics NAV, go to Departments > Sales & Marketing, and then click Sales.
  2. Go to Lists > Customers.
  3. Select a customer.
  4. In the Edit - Customer Card window, go to Invoicing, type Exemption Certificate Number in Tax Exemption No, and then click OK.
