Streamlined Sales Tax (SST) and Marketplace Sellers

Can I be part of the SST program if I sell through a marketplace?

Yes, a marketplace seller can participate in the SST program.

Transactions calculated by marketplace facilitators can be imported into AvaTax to be included in SST filings.

If the marketplace remits on your behalf, and you are importing these transactions to AvaTax, you must ensure the proper location codes are used to identify these transactions as marketplace remits. The marketplace remits transactions will be excluded from the SST returns. SST sellers are not required to recalculate (or upload) marketplace remits transactions.

You are also able to qualify for SST if your entity is the marketplace facilitator. Your transactions will be subject to the SST transaction requirements.
