Sales tax registration services, handled.
Registering in a new state takes hours you don't have. We handle every state registration from start to finish, so you stay compliant without touching a portal.
Trusted by partners worldwide.
Registration is our job, not yours.
Fully managed.
Not software you log into. A team that gathers what's needed, files with the state, and hands you the credentials when it's done.
No registration backlogs.
Typical turnaround is 2 to 4 weeks per state, often faster. New nexus doesn't sit in a queue while your exposure grows.
Accountable for the work.
If a registration error is ours, we fix it. No finger-pointing, no extra invoice, no back-and-forth with the state on your end.
Sales tax registration, end to end.
Every state, every jurisdiction.
We register you in any of the 50 states, plus the local jurisdictions that require their own filing. Each state wants something different, and we already know what.
You share details. We file.
Tell us your entity type, states, expected revenue, and any prior registrations. Our team submits to each state portal, then delivers your credentials and adds the state to your compliance calendar.
Behind? We'll catch you up.
Already have nexus you never registered for? We register you retroactively and build a plan to address back exposure without inviting an audit.
New states, caught early.
Registration isn't a one-time event. As you grow into new states, we track when a new registration is due and file before you're exposed.
Not just a tool. A sales tax team.
Every Zamp subscription is a managed service. The platform calculates and tracks, and our tax specialists register, file, remit, and answer the state.
