Frequently Asked Questions
How often do I file sales tax?
Filing frequency (monthly, quarterly, annual) is set by each state based on volume. Check your registration notice or state portal for the assigned schedule and due dates.
What are exemption certificates?
Certificates document why a sale was not taxed (resale, exempt organization, etc.). Keep them on file; states can assess tax later if certificates are missing or invalid.
How do marketplace facilitators affect filing?
Many marketplaces collect and remit tax on facilitated sales. You still need reports to reconcile what you remit vs what the marketplace remitted. Rules vary by state.
What records should I keep after filing?
Keep the filed return, payment confirmation, sales journals, exemption certificates, and marketplace reports for the period required by each state.
