TaxJar pricing in 2026: the order tiers, the filing fees, and what it adds up to

Two businesses on TaxJar Professional at the 1,000-order tier pay the same $499 a month and can end the year thousands of dollars apart. The subscription is fixed; the filing calendar is not.

A company collecting in four states that file quarterly generates 16 returns a year. Four are covered by the included credits, so twelve cost $55 each: $660. A company collecting in twelve states that file monthly generates 144 returns. Four are covered, so 140 cost $55 each: $7,700. Same software, same order volume, a $7,040 difference driven entirely by filing frequency, which the states assign based on your volume in each one and which you do not choose.

This is why "how much does TaxJar cost" has no single answer, and why the slider on the pricing page only tells you about a third of the story. Count your returns before you compare plans.

TaxJar's meter is more inclusive than the word "order" suggests. Each sale, refund, or return imported into TaxJar counts as one order. CSV imports count by unique order ID. Orders created through the API count. API tax calculations and rate lookups count as one tenth of an order each, which only applies on Professional.

Two consequences are worth planning around. First, every imported order counts regardless of where it went or whether you collected tax on it, so international orders and orders in states where you have no nexus are on the meter. Second, marketplace orders count even when the marketplace already remitted the tax, so an Amazon-heavy seller can be paying for volume that generates no filing obligation.

A high-return category such as apparel feels this twice: the sale counts, and the refund counts again. If your return rate is 25%, your effective order count is 125% of your sales.

If you cross your tier in a given month, TaxJar charges a flex fee rather than upgrading you permanently. The fee is the difference between your plan price and the price of the tier that matches that month's volume, and you go back to your original plan the following month.

Set against a permanent upgrade, a seasonal business comes out ahead here. A Starter customer on the 500-order tier who does 900 orders in November pays the 1,000-order price of $99 that month instead of $59, a $40 difference, and is back at $59 in December. Compare that with vendors whose terms upgrade you to the higher tier for the rest of the term.

The thing to watch is that it is automatic and calculated per month, so growth shows up as a bill before it shows up as a decision. If three consecutive months trigger flex fees, you are on the wrong tier and annual billing on the correct tier is probably cheaper.

The two most-compared vendors in this category do not price the same unit, which is why "which is cheaper" depends entirely on the shape of your business.

Avalara Core Compliance lists at $799 per state per year, or $79 per state per month, for companies under $50M in revenue, and includes calculation, Managed Returns filing and remittance, notice management, and 50-state nexus monitoring. You pay by state, and filing is in the price. TaxJar charges by monthly order volume and bills filing separately per return.

So the comparison turns on your ratio of states to orders. Ten states, 1,000 orders a month, monthly filing: Avalara is about $7,990 a year on list price, TaxJar about $12,368. Three states, 200 orders a month, quarterly filing: Avalara is about $2,397, TaxJar about $968. Both sets of numbers are our arithmetic on published prices and exclude registrations, which are $403 per location at Avalara and $299 per state at TaxJar.

Two caveats keep this honest. Avalara does not publish the transaction limits on its per-state plans, and its terms default to an automatic tier upgrade when you exceed one, so its figure is a floor. TaxJar's figure can come down through annual billing and prepaid filing bundles, which it does not price individually.

TaxJar and Zamp sell different things, and the pricing model follows from that. TaxJar is software you operate: you connect the channels, watch the nexus dashboard, decide when to register, and either file yourself or buy AutoFile credits per return. Support is email on Starter, email and phone on Professional. Notice management is not listed as an included service on either plan, and no penalty guarantee appears in the terms.

Zamp is a managed service. Its pricing page lists a paid U.S. plan covering rooftop-accurate calculation, nexus monitoring and registration, filing and remittance, end-to-end notice management, and dedicated U.S. tax expertise, plus a U.S. and Canada plan. Pricing is a scoped quote rather than a per-order meter, and the switch page says most teams are live within a week and offers a buyout program for teams still inside another vendor's contract. Under the Zamp Commitment, penalties or interest from a Zamp-managed calculation or filing are covered, with no cap stated. Those are Zamp's own claims, linked so you can read them in full.

Consider Zamp when the filing calendar is what's growing: many states, monthly frequencies, notices arriving, and a finance team spending hours on work that per-return fees only partly cover. Stay with TaxJar when you file in a few states, your volume is predictable, and you want a self-serve price on a public page. Zamp does not publish list prices, so this page makes no claim that it is cheaper. The comparison worth making is a Zamp quote against a TaxJar quote that includes a full year of returns.

Starter is $39 a month at 200 orders, $59 at 500, $99 at 1,000, $219 at 2,500, and $319 at 5,000 or more. Professional is $99, $249, $499, $1,199, and $1,599 at the same tiers. Annual billing saves 10% or more. Filing and registrations are charged separately.

Each sale, refund, or return imported into TaxJar counts as one order, including orders to any state or country whether or not you collected tax, and including marketplace orders the facilitator remitted. API tax calculations and rate lookups count as one tenth of an order each on Professional.

Starter includes two filing credits a year, allocated every six months, and Professional includes four, allocated quarterly. Beyond those, filings are $50 each on Starter and $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. Credits and bundles are non-refundable.

Yes, $299 per state, and only for customers already on a paid plan. TaxJar can register for nexus created by third-party inventory storage such as Amazon FBA, but says it cannot register for nexus from other types of inventory storage or from employees located in a state.

TaxJar has been a Stripe company since Stripe announced the acquisition, and the wordmark on taxjar.com says so. TaxJar still sells both plans, still offers a 30-day trial, and its support articles were updated through 2026. Its pricing page also tells visitors that if they are a Stripe customer, Stripe Tax might be a good fit, and some 2026 reviewers describe friction reconciling data between Stripe and TaxJar. If you are already on Stripe, price both before choosing.

It depends on your ratio of states to orders. TaxJar prices by monthly order volume and bills filing per return; Avalara Core Compliance lists at $799 per state per year with filing included. On list prices, three states filing quarterly at 200 orders a month is roughly $968 a year on TaxJar against $2,397 on Avalara, while ten states filing monthly at 1,000 orders a month is roughly $12,368 on TaxJar against $7,990 on Avalara. Both figures are our arithmetic and exclude registrations.
