Your SaaS Sells to Every State. Do You Know Where You Owe Tax?
SaaS nexus is different. Most states tax software, but the rules are inconsistent. NexusFlag tracks your exposure across all 50 states — starting at $49/mo.

The SaaS Tax Problem
SaaS companies face a uniquely complicated tax landscape. Here is why.
More than 30 US states impose sales tax on SaaS products. That number has grown steadily since 2018 and is still increasing. Texas, New York, Pennsylvania, Washington, and Ohio are among the largest.
A single Product Hunt launch, a viral tweet, or organic Google traffic can put paying customers in 30 states within weeks. Unlike an e-commerce store that ships to one region, SaaS has no geographic friction.
Post-COVID, remote employees are everywhere. A developer working from Texas creates physical nexus in Texas for your company — even if your headquarters is in Delaware and you have zero Texas customers.
Tangible personal property, digital automated service, or professional service. How your state classifies SaaS determines the tax rate — and some states classify the same product differently depending on how it's delivered.
A SaaS company with $200K ARR and customers spread across 30 states likely has economic nexus in 5 to 10 of those states — and physical nexus in any state where a remote employee works. Most SaaS founders don't find out until a state audits them.
How NexusFlag Solves It for SaaS
Three things SaaS companies actually need — in one dashboard.
Track nexus across all states
Connect your Stripe account and NexusFlag pulls revenue by customer billing state automatically. No spreadsheets, no manual exports. We track your trailing 12-month totals against every state's threshold in real time.
Know which states tax your software
SaaS taxability varies by state and our rules database is updated as laws change. When you cross a threshold in a state that taxes SaaS, we flag it immediately. When you cross a threshold in a state that exempts SaaS, we tell you that too — you still need to register.
See state-by-state SaaS taxability →Get alerts before you cross
Email alerts fire at 50%, 80%, and 100% of each state threshold. You have time to register, set up collection, and stay ahead of compliance obligations — instead of finding out you're already over.

Common questions from SaaS founders
Is SaaS taxable in all states?
No. As of 2026, approximately 30 states tax SaaS, while the rest either exempt it or have not issued clear guidance. States that clearly tax SaaS include Texas, New York, Pennsylvania, Washington, and Ohio. States that do not tax SaaS include California, Florida, Georgia, and Virginia. There is no federal rule — each state decides independently.
Do I have nexus if my employees work remotely in another state?
Yes. A remote employee working from a state creates physical nexus for your company in that state, regardless of your company's headquarters or how much revenue you generate from that state. Physical nexus from remote workers is distinct from economic nexus — it is triggered by the employee's presence, not your revenue. This applies to full-time employees; contractors generally do not create nexus unless they perform activities closely tied to your core business.
How does NexusFlag work with Stripe?
NexusFlag connects to your Stripe account and pulls revenue by customer billing state. We aggregate that data against each state's economic nexus threshold on a trailing 12-month basis and alert you when you're approaching or have crossed a threshold. NexusFlag handles the monitoring — Stripe Tax handles the calculation and collection after you register. The two tools complement each other.
What if I sell both SaaS and physical products?
Both revenue streams count toward economic nexus thresholds in most states. The threshold is based on total sales into the state, not just taxable sales. Once you cross the threshold, you must register. After registration, you collect tax based on each product's taxability: your SaaS product in states that tax SaaS, and your physical products wherever physical goods are taxable (almost everywhere). NexusFlag tracks both streams together in the same dashboard.
How quickly can I get set up?
Most SaaS companies are up and running within 15 minutes. Connect your Stripe account, select the states you want to monitor, and NexusFlag immediately calculates your current exposure based on historical transaction data. Alerts activate automatically. You don't need to import spreadsheets or manually enter revenue figures.
Stop guessing. Start monitoring.
Connect Stripe in 2 minutes. NexusFlag shows you every state where you're approaching or past the threshold — so you can act before the state does.
