Most sales tax vendors make you call sales. TaxJar publishes a price and hands you a slider: drag it to your order volume, read the number. Ten seconds, done.
The number is real. It is also about a third of the bill. Filing is charged per return once a small annual credit allowance runs out. Registrations are charged per state. And the meter that decides which tier you land on counts refunds, returns, and orders in states you don't even collect in. Below: the whole published ladder, the two lines that sit beside it, and how the total lands next to Avalara's per-state model.
Disclosure: Zamp publishes this page and sells a managed sales tax service that competes with TaxJar. Every TaxJar figure below comes from TaxJar's own pricing page, support articles, or terms, checked on September 18, 2026, and anything about Zamp is linked to the Zamp page it comes from.
Four things to settle before you pick a tier, because each one changes the annual number more than the plan choice does.
Your real order count, including refunds. Pull twelve months of sales, refunds, and returns, not just sales. Add API calls divided by ten if you will use the calculation API on Professional.
Your filing calendar, not your state count. Ten states filing monthly is 120 returns; ten states filing quarterly is 40. At $55 a return that difference is $4,400 a year.
Whether a bundle pays for itself. Bundles need an annual subscription and are non-refundable. Ask for the price of the specific bundle size you need before you commit to annual billing.
Who handles a notice. Notice management is not listed as an included service on either plan, and no accuracy or penalty guarantee appears in TaxJar's terms. If a state disagrees with a return, decide now whose problem that is.
The published price ladder
Two plans, Starter and Professional, five order tiers each. Starter: $39 a month at 200 orders, $59 at 500, $99 at 1,000, $219 at 2,500, $319 at 5,000 or more. Professional: $99, $249, $499, $1,199, $1,599 at those same five tiers. Annual billing takes 10% or more off either one. The pricing page only ever shows one tier, so we walked the slider from end to end to get the full ladder.
Starter is the self-serve plan: a free 30-day trial, no credit card, up to three data import integrations, email support with a guaranteed response time, and two AutoFile credits a year. Professional adds up to ten integrations, an archive of historical sales tax data, phone support, a dedicated onboarding specialist and Customer Success Manager, and four AutoFile credits a year. The Professional button says Contact sales rather than Start a trial, so the higher plan runs through a person.
What TaxJar counts as an order
Here is where budgets go wrong. An order, to TaxJar, is each sale, refund, or return imported into the product. Sent to a state you don't collect in? Counts. Sold through a marketplace that already remitted the tax? Counts. Refunded last week? That's a second order on the meter. On Professional, API tax calculations and rate lookups pile on at a tenth of an order each, so 10,000 calls adds another 1,000 orders.
Going over is not a penalty. TaxJar charges a flex fee, the difference between your plan and the tier that matches that month's volume, and puts you back on your original plan the next month. It also means a strong quarter shows up on the bill within the month.
The two lines that are not in the subscription
Filing is the big one. AutoFile is not included in the monthly price; you get credits. Starter gets two a year, allocated once every six months. Professional gets four, allocated quarterly. After that, each return is $50 on Starter or $55 on Professional. Annual subscribers can prepay bundles of 25, 50, 100, or unlimited filings, which TaxJar prices from $1,125 to $12,000 depending on plan and bundle size without publishing the price of each bundle. The unlimited bundle covers 540 credits and expires after a year; the smaller bundles do not expire, and none of them are refundable.
Registrations are $299 per state, and only for customers already on a paid plan. TaxJar will register you where third-party fulfillment such as Amazon FBA created your nexus, but says it cannot register for nexus from other kinds of inventory storage or from employees in a state, which is the common case for a company with remote staff.
If you would rather not do the math
The reason TaxJar's total is hard to predict is that it moves with two meters you do not control: how many orders and refunds flow through, and how many returns your filing calendar generates. Zamp, which publishes this page, prices the other way: a scoped quote for a managed service where a tax team handles registrations, filings, remittance, and notices, with no per-order meter and no per-return fee. Zamp doesn't publish list prices either, so nothing here claims one is cheaper than the other. If you want a number to set beside a TaxJar quote, book a call or start with the free nexus and exposure assessment.
What it adds up to
Two worked examples, using TaxJar's published list prices and monthly billing. A small seller doing 200 orders a month who files quarterly in three states pays $468 a year for Starter, uses its two credits, and buys ten more filings at $50, so about $968 a year plus $897 in one-time registrations. A growing brand doing 1,000 orders a month that files monthly in ten states pays $5,988 a year for Professional at the 1,000-order tier, uses its four credits, and buys 116 more filings at $55, so about $12,368 a year plus $2,990 in registrations. Annual billing and a prepaid filing bundle would both bring the second number down; we cannot say by how much, because TaxJar does not publish bundle prices individually.
Both examples show the same thing: the subscription is modest, and the filing calendar is what moves the total. One TaxJar customer on G2 who files in 27 states put it plainly: the software saves him twenty hours a month, and filing is something it does "for an additional fee."
Where to go from here
If you file in a few states and your order volume is steady, TaxJar's published price is close to the price you will pay, and the 30-day trial costs nothing to test. If your filing calendar is monthly across many states, price the returns first and the subscription second, and ask about a bundle before you sign an annual plan. If you would rather hand the whole calendar to a team and get one scoped number, talk to Zamp; the free assessment is the fastest way to get something to compare.
