Register for sales tax where you owe it.
Sales tax registration is a separate filing from formation or foreign qualification. We file your sales tax permit application in every state where you have economic or physical nexus, and set up your books to track collected tax.
Sales Tax Registration, plainly.
Sales tax is collected by sellers, then remitted to the state. Whether you have to collect depends on nexus: economic nexus (you crossed the state\u2019s revenue or transaction threshold), physical nexus (you have inventory, an office, or employees in the state), or marketplace nexus (you sell on Amazon, Etsy, Walmart, who collect for you in some states).
After the Supreme Court\u2019s 2018 Wayfair decision, every state with sales tax can require out-of-state sellers to collect once they cross a threshold (most commonly $100,000 in sales or 200 transactions per state per year). This means an e-commerce seller can hit nexus in 10+ states without ever stepping foot in any of them.
We assess where you have nexus, file the sales tax permit application in each state, set up sales tax tracking in your books, and connect to filing software (Avalara, TaxJar) for ongoing returns. Each state is its own filing with its own form and fee.

How we deliver, end-to-end.
Four-step path from request to confirmation. State and IRS turnaround varies; our steps run in parallel where possible to compress the timeline.
Intake + scope
You tell us what you need through a short intake form (or a call for complex matters). We confirm scope, surface any gating issues (deadlines, missing documents, entity status), and quote any state fees that pass through at cost.
Prepare + verify
Our specialists draft the filing, verify entity details against state databases, run internal QA, and route any items needing your sign-off. You see drafts before anything gets submitted.
File with the authority
We submit directly to the state Secretary of State, FinCEN, IRS, USPTO, or whichever authority your filing requires. We pay state fees at cost and track the submission identifier in your account.
Confirmation + vault
Stamped certificate, IRS notice, or filing receipt arrives in your SOC 2 encrypted document vault the moment we receive it. Next filing deadline auto-added to your compliance calendar where applicable.
