Why does Zamp need my marketplace and wholesale orders?

Roughly half of all states include marketplace-facilitated sales when measuring a company’s sales against the state’s nexus thresholds. So, even though a company is not responsible for collecting or remitting the taxes generated by marketplace-facilitated sales, many states will still count them when determining whether a company has to register for a sales tax license.

Additionally, marketplace orders are required in state filings as exempt transactions in accordance with the state’s Marketplace Facilitator Law.
