Once your sales into a state cross its threshold, you owe sales tax there and are expected to register before the next taxable sale, whether or not you noticed you crossed the line. The thresholds are not uniform. California and Texas both set a flat $500,000 with no transaction count, New York requires both $500,000 and more than 100 separate sales, and many states sit far lower at $100,000 or 200 transactions, where a high-volume, low-price seller trips the count without nearing the dollar figure.
Our sales tax compliance services find every state where you have crossed that line and put your registration, collection, and filing in order before a state finds it first.
We examine the states you sell into: where physical presence or economic activity has created an obligation.
We register for a seller's permit or use tax account in each state where you have nexus.
We advise on setup, so the correct rate is charged at checkout, including local and district rates layered on the state rate.
We file on each state's schedule, including zero returns for periods with no sales.
We ensure that sales that a marketplace already taxes are reported and deducted correctly, not taxed twice.
The result is a defined map of where you are registered, what you collect, and when you file.
We pull your sales by state and channel and test each state against its physical and economic nexus rules. The output is a list of where you must register, where you are close, and where you can wait.
We register in the states that triggered nexus and set up collection so the right rate applies by destination, not a flat guess.
Returns go out on each state's frequency, the marketplace-collected sales are reconciled, and the calendar is managed so nothing lapses.
Compliance is judged on whether the filings are right and on time, across every state, without you watching the calendar.
Most exposure comes from sellers who registered in their home state, kept growing, and never rechecked nexus as their sales spread into new states.
Cost depends on how many states you have nexus in, your filing frequency in each, your sales volume and channels, and whether there is back exposure to clean up before going current. We quote after the nexus review, since that sets the real size of the job, not a flat rate that ignores how many states you actually file in.
Stored inventory is the one most sellers miss. It creates a physical nexus on its own, regardless of sales volume, so a business using out-of-state fulfillment (Amazon FBA or third-party warehouses) can owe registration in states it never sold much into. Exposure for an unregistered period stays open: California can assess up to eight years back when no return was filed, against three years once you are filing.
You do not have to know which states you have missed; that is what the nexus review is for. If you turn out compliant, we will tell you rather than sell you filings you do not need.
Tell us your sales channels and roughly where you sell, and we will map where you have to register and file. You can share detailed sales-by-state figures once we talk.
