Rule coverage
Decision support, not tax theater
See where you likely need to register, where marketplace rules muddy the answer, and where you can stand down.
TaxNexus compresses the first-pass analysis a SALT consultant would do anyway. You answer a few operator-level questions. The tool returns a state board, taxability caveats, and a clear workflow handoff.

No triage board yet
Once you run the intake, TaxNexus will split your states into likely nexus, review-needed, and likely no nexus so the next move is obvious.
Why this exists
Operators need triage, not a 50-state reading assignment.
Most nexus research tools dump you into charts and legal references. Useful later, terrible first. This tool starts with business facts, then translates them into likely nexus, likely no nexus, and review-needed states so the team can decide what deserves real legal or workflow follow-up.
What does TaxNexus do?
TaxNexus is a sales tax nexus calculator for multi-state operators. Enter your business model, revenue distribution, and transaction volume to get state-by-state triage showing where you likely need to register, where you should review with a tax advisor, and where you can stand down. Results include taxability briefings, registration priorities, and evidence collection guidance—delivered in under 5 minutes.
Who is TaxNexus for?
TaxNexus is for multi-state e-commerce sellers, SaaS companies expanding across state lines, CFOs and controllers managing sales tax compliance risk, tax consultants conducting nexus studies, and marketplace sellers evaluating where facilitator collection ends and direct obligations begin. If you're crossing $100K revenue or 200 transactions in multiple states, you need nexus triage.
How does TaxNexus work?
Select your business model and transaction type (SaaS, digital goods, services, or physical products). Enter multi-state revenue and transaction assumptions. TaxNexus calculates economic nexus thresholds, detects marketplace facilitator coverage, flags physical presence signals, and generates a triage board grouping states by likely nexus, review needed, or likely no nexus. Download an operator brief with registration priorities and evidence checklists.
Is TaxNexus free?
Yes. TaxNexus is free to use with no signup required. All calculations run in your browser—no data is sent to our servers. Export your operator brief as a text file for handoff to your tax advisor or accounting team.
What sales tax compliance standards does TaxNexus support?
TaxNexus tracks economic nexus thresholds across all 50 US states following South Dakota v. Wayfair (2018) standards, marketplace facilitator laws, Streamlined Sales Tax Agreement member state rules, and state-specific SaaS taxability guidance. Rule freshness metadata shows when each state's threshold was last updated.
Which states have economic nexus thresholds?
All states with sales tax have economic nexus thresholds. Most use $100,000 in annual revenue or 200 transactions. California uses $500,000 revenue-only. Texas uses $500,000 revenue-only. New York, Florida, and Pennsylvania use $100K or 200 transactions. TaxNexus flags states where you're within 20% of the threshold so you can monitor growth and register before crossing.
FAQ
Common operator questions
- Does marketplace-only revenue always mean no registration? No. Some states still require review because thresholds can still matter for notice, reporting, or mixed-channel sales.
- What about Alaska? Alaska has no statewide sales tax, but local remote seller rules still create compliance work. That is why TaxNexus treats Alaska as review-needed, not “ignore it.”
- Does SaaS taxability matter if I already crossed nexus? Yes. Nexus tells you where you may need to collect. Taxability tells you whether the product is actually taxable in that state.
