Questions about the nexus study
What is a nexus study?
A nexus study is a structured analysis of where your business has sales tax collection obligations across US states. It covers economic nexus (triggered by crossing revenue or transaction count thresholds), physical nexus (triggered by employees, offices, inventory, or contractors in a state), and marketplace facilitator coverage. CPAs charge $5,000–$15,000 for this analysis. NexusFlag automates it.
How accurate is the automated analysis?
The engine uses published state threshold data — the same data CPAs reference. For the vast majority of businesses, the threshold analysis is identical. Where we differ from a CPA engagement is in product taxability edge cases (e.g., is your SaaS taxable in this state?) and negotiation with state DORs. For straightforward businesses with known taxable products, the NexusFlag report is sufficient.
Do I need an account to buy the study?
No. You enter your business data, pay $299 via Stripe, and receive your report link by email immediately. No account, no subscription.
What if my revenue data isn't precise?
Use your best estimates. The purpose of a nexus study is to identify states where you've clearly crossed thresholds or are approaching them — not to produce accounting-grade numbers. Round to the nearest thousand. States are looking for businesses that are materially over the threshold, not businesses that are a few hundred dollars over.
Is this legal or tax advice?
No. NexusFlag provides automated analysis tools — not legal or tax advice. It does not create an attorney-client or accountant-client relationship. For advice on your specific situation, consult a CPA or sales tax attorney. The NexusFlag Research Team validates threshold data but cannot advise on individual circumstances.
