Shopify Tax calculates US sales tax at checkout from product categories and buyer addresses, and shows states where you may be approaching an economic nexus threshold. It's free until $100,000 in US sales, then 0.35% per order (0.25% on Plus) in states where you collect. It doesn't register you, file returns or remit, and Shopify's own automated filing is closed to new enrolment. You file yourself, use a filing service or hire a specialist.
The work runs in this order:
- Find where you have nexus, through physical presence or each state's economic threshold.
- Register in those states before you start collecting there.
- Switch on collection in Shopify for each registration, then check product categories and exemptions such as B2B resale certificates.
- File and pay on each state's schedule.
- Reconcile what Shopify collected against what you filed, every period. A difference means something needs fixing before the next return, not after.
Selling abroad follows the same split. Shopify VAT collection runs on the registrations you enter, such as a local EU registration, OSS, IOSS or a UK VAT number, and filing and paying stay with you. Managed Markets is the only route where a partner, acting as merchant of record, remits for you.
