Intermediate Quick Answer
Does economic nexus apply to B2B-only sellers, not just B2C?
⚡ TL;DR
Yes. Economic nexus thresholds are based on gross sales into the state regardless of buyer type. A B2B seller with $150K in sales to business customers has nexus and must register, even if every transaction is exempt via resale certificate. Registration is required before you have legal standing to accept exemption certificates in most states.
Yes. Economic nexus thresholds apply to B2B sellers. The threshold measures gross sales into the state, not taxable sales, not sales to consumers. Crossing it requires registration regardless of how many of those sales are ultimately exempt.
Key takeaways
- Economic nexus thresholds are based on total gross sales (or transaction count) into the state, not on taxable sales or buyer type
- A B2B seller with $150K in sales to business buyers in a state has nexus and must register, even if all those sales are exempt via resale certificates
- Registration is required before you can legally accept exemption certificates in most states, without a permit, you have no standing to accept them
- Registered B2B sellers with 100% exempt sales still file returns on schedule, they file zero returns showing all sales as exempt
- The practical burden for B2B sellers is certificate management, not tax collection, but registration is still the legal prerequisite
- If any B2B sales are not covered by a valid certificate (buyer failed to provide one, certificate expired, etc.), those sales are taxable and you’re liable for uncollected tax
Frequently asked questions
Does economic nexus apply if I only sell to businesses?
Yes. Economic nexus thresholds are based on gross sales into a state, not on the nature of the buyer. A seller who makes $150,000 in sales to business customers in a state has crossed a $100,000 threshold and must register, even if every one of those transactions is exempt because the buyer provided a valid resale certificate. Registration is required; it's the certificate management that makes those individual transactions non-taxable.
If my B2B sales are all exempt, why do I need to register?
Because the threshold trigger and the taxability determination are separate questions. Crossing the threshold requires registration. Whether individual transactions are taxable depends on whether valid exemption certificates are on file. Without registration, you have no legal authority to accept exemption certificates in that state, and you have no mechanism for filing returns (even zero returns) if all sales are exempt.
