Most sales tax firms take a percentage of what passes through them. Your bill then grows every year your business does, even though filing a return on $2M of sales is the same work as filing one on $200K.
We charge per return, per state, per engagement. What’s published below is the price — not a starting point that moves once we’ve seen your books.
Talk to an expert about where you actually stand. We’ll tell you what you need, in what order — and if you don’t need us yet, we’ll say that too.
Where you’ve triggered nexus, on what date, and what open liability you’re carrying — across all 50 states.
Monthly compliance, off your desk. We reconcile before anything is filed, so we’re checking the number rather than submitting whatever your system produced.
Any state or local jurisdiction in the United States or Canada, including the ones that want a bond or an in-state responsible party. State fees passed through at cost.
We file the VDA on your behalf and carry it through to signed — capped lookback, penalties waived.
We step in at any point — a first notice, or a case you can’t carry alone any more. Fees depend on the engagement, but commonly they’re a percentage of the reduction we achieve: cut a $400,000 assessment and our fee comes out of that saving.
See audit defense →We don’t warehouse your certificates ourselves — we license the platform that fits your systems and set it up around them. The value is knowing which one suits your stack and where you’re heading, rather than the one that markets hardest.
See certificate management →Selection, implementation, and configuration audits across Avalara, Vertex, and TaxJar. We take no commission from any platform, so “you don’t need one yet” costs us nothing to say.
See automation advisory →Buy side or sell side. Tell us the deadline and we’ll tell you what fits inside it — including what can be quantified against escrow before signing.
See due diligence →We find sales tax you paid but never owed and file to get it back. If there isn’t enough there to be worth it, we’ll tell you rather than bill you to find out.
See overpayment recovery →Most businesses need two or three of these, in a particular order. Filing before the back period is resolved is how people accidentally tell a state where to look.
Until the footprint and liability are quantified, every other decision is a guess with a price tag attached. The analysis makes the rest of this list concrete.
“I’ve only worked with you all for a few months, but the team at TSTP have made an area that is daunting for a non-American extremely simple. You’ve taken all the stress out of the process. If I’m ever in need of assistance with Sales Tax in the future I’ll be coming your way.”
We’ve been doing this since 1992. Most of these exist because of a business that came to us after being burned by one of them somewhere else.
Filing a return on $2M of sales takes the same work as filing one on $200K. Pricing on volume means paying more every year for identical work.
States write to you. Handling that correspondence is part of monthly compliance, not a billable event each time an envelope arrives.
We aren’t a reseller and take no commission on any platform. If you don’t need one yet, we’ll tell you that, and it costs us nothing to say.
If the scope genuinely changes we’ll say so before doing the work. What we won’t do is quote low to open the engagement and revise upward once you’re committed.
A rate card only means something if the work behind it is done by people who do this exclusively. Sales and use tax is the only thing this firm has done since 1992.
The first call is with one of them, not a sales rep, and it costs nothing.
If you don’t know where you stand, a nexus risk analysis — everything else is a guess until that’s answered. If you know and filing is the problem, go straight to the return service. If a state has already written to you, audit defense today; there’s usually a deadline running.
Monthly compliance is an ongoing engagement you can end. One-time work — an analysis, a registration, a VDA — is exactly that.
A registration is a form. A voluntary disclosure is a negotiation with a state, an anonymous approach, a reconstructed liability calculation for the back period, and the filings that close it out. It’s priced per jurisdiction because each one is a separate agreement.
Regularly. We handle the sales and use tax workstream alongside a client’s existing accountants rather than in place of them, and we’re comfortable staying in the background.
That’s the common case — an analysis leads to registrations, VDAs, and then monthly filing. We’ll put the whole sequence in one quote with the order it should happen in, so nothing gets filed before it should.
Where you sell, where you’re registered, and what prompted you to look. That’s usually enough for a real number on the first call — which is free.
