Why It Matters
Why Sales Tax Registration Matters
Sales tax is a state-level obligation triggered by "nexus" — a connection to the state through physical presence or, increasingly, sales volume. Registering in the right states, and only those, is the whole game.
Register Where You Should
A nexus review first, so you do not register everywhere out of fear.
Satisfy Marketplaces
Platforms often ask sellers for a valid permit number.
Reduce Exposure
Unregistered sales can accumulate uncollected tax liability.
Collect Legitimately
A permit is what allows you to collect sales tax at all.
Unlock Resale Certificates
Registration is usually the prerequisite for buying stock tax-free.
Built for Non-Residents
We register foreign-owned U.S. businesses as routine work.

Common Mistakes We See
Registering in all 50 states
Every registration creates a permanent filing duty. More is not safer — it is just more work forever.
Ignoring where inventory sits
Storing stock in a state — including in a fulfilment warehouse — is a classic nexus trigger.
Registering then never filing
Once registered you generally must file returns, even for zero sales.

Frequently Asked Questions
Which states do I need to register in?
It depends on where you have nexus — through physical presence, inventory storage, or sales volume crossing a state threshold. Our review looks at your actual activity rather than registering you everywhere.
What is economic nexus?
Broadly, it means enough sales into a state can create an obligation there even with no physical presence. Thresholds differ by state and change, which is why we review rather than assume.
Does storing inventory in a warehouse matter?
It commonly does. Inventory sitting in a state — including in a fulfilment centre — is one of the most frequent nexus triggers for marketplace sellers.
Do I have to file returns after registering?
Generally yes. Registration creates an ongoing filing duty, often even for periods with zero sales. We explain your filing frequency when the permit is issued.
Are state fees included?
No. Our fee starts at $150 per state. State registration fees and any deposits are charged separately at cost and confirmed before we file.
Can non-U.S. residents register?
Yes. We register foreign-owned U.S. businesses regularly — an EIN and your company details are the usual starting point.
