How does Reverb assist with US Tax calculation?

As of July 8th, 2019, Reverb automatically calculates tax rates for all US states that are active Marketplace Facilitator States.

What do sellers need to do?

If you add additional states in which you collect taxes from your Tax Policy Settings, you'll no longer need to manually enter a tax rate. Simply select states to start collecting in and click "Add Tax Policy".

Additional Information:

To learn more about tax collection threshold for different states, please refer to this state-by-state breakdown of Economic Nexus thresholds provided by our tax partner Avalara.

For tax advice, you should contact a tax professional.
