No, and that is where the complexity lies. SaaS is taxable in states like Tennessee and Vermont, but exempt in others like Michigan, while states like Colorado have specific home-rule jurisdiction variances. Zamp’s engine manages these rules automatically so you don’t have to track legislative changes.
Yes. In many states, having a single remote developer or sales rep creates “physical nexus,” obligating you to collect tax on sales in that state even if you haven’t hit the economic revenue threshold. Zamp monitors both physical and economic triggers to keep you compliant.
Many SaaS companies sell to non-profits or educational institutions that are tax-exempt. Zamp manages the collection and validation of exemption certificates directly, ensuring you don’t charge tax to exempt customers while maintaining the audit trail you need.
Absolutely. Our integrations with platforms like Stripe and Chargebee are designed to handle the dynamic nature of SaaS billing, including upgrades, downgrades, and metered usage, ensuring tax is calculated correctly on every invoice.
Yes. We regularly help SaaS companies resolve back taxes and clean up compliance issues through VDAs (Voluntary Disclosure Agreements) before an acquisition or funding round. Addressing this proactively is always cheaper than waiting for an audit.
