Adding your Zamp API Key

Enabling Fallback Rates
It is worth noting that BigCommerce has safety net options available in cases where it canât communicate with the default tax provider. For example, if your Tax Providerâs services were unreachable for sales tax calculations.Chat with your Zamp Onboarding Manager regarding setting general fallback rates for the states where you have Nexus.
5
Configuring the Zamp Tax app
- **Taxable states -Â **Taxable states should coincide with states configured in your Zamp account. Your Onboarding Manager will be available to help determine which states should be added to this multi-select list.
- Having a state listed as a Taxable state in your configurations means it is one Zamp will produce sales tax calculations for, so long as the customerâs shipping address state matches.
- Any state not listed as a Taxable state will not have sales tax calculations occur. These would be states that you arenât required to remit sales tax in. For example, not having a physical presence (nexus) in the state and not having met the economic nexus thresholds.
- **Enable Zamp calculations -Â **Setting âAllow Zamp to handle your Tax Calculations?â will have your checkout experience utilize Zamp for sales tax calculations.
- This toggle gives you the opportunity to decide if youâd like to use Zamp to calculate sales tax for you.
- **Enable Zamp transaction reporting -Â **Setting âSend your transaction reports to Zamp?â will have your transactions report to Zamp when a transaction has been paid for or has been marked as âCompletedâ.
- This toggle gives you the opportunity to decide if youâd like to use Zamp for transaction reporting, which will allow us to file sales tax returns for you.
