Sales Tax — frequently asked questions
What is sales tax nexus?
Nexus is a connection to a state — through physical presence or enough sales — that requires you to collect and remit that state's sales tax. We determine where you have it.
Do I owe sales tax in every state I sell to?
Not necessarily. You owe where you have nexus. Economic-nexus thresholds vary by state, and we map yours precisely.
Can you handle Shopify and Amazon sales tax?
Yes — we handle e-commerce and marketplace sales tax, including platform collection settings and marketplace-facilitator rules.
What if I already have unfiled sales tax?
We can help you get compliant and address back-filings, often reducing penalties through voluntary disclosure where it applies.
