TaxJar in brief

TaxJar publishes a real rate card, which is rare in sales tax software.

Price: $39 / mo (Starter) at 200 orders a month · Subscription by monthly order volume, plus per-filing AutoFile credits
Best for: US multichannel ecommerce sellers who operate compliance in-house
Watch out for: You give up everything outside the United States.

The short answer

Buy TaxJar if you sell in the US across several channels, you want the sales tax subscription priced off order volume rather than a sales conversation, and you can live with filing billed as credits on top. The published $39 and $99 figures mean you can model a budget before anyone calls you back, and the 30-day free trial with no credit card means you can test the data import path first.

Skip it if you need VAT, GST or any non-US indirect tax, because TaxJar is a US sales tax product and that gap is structural. Skip it if you file in a long list of states every month, since AutoFile credits at $50 or $55 each will outgrow the subscription. And skip it if you want a managed service where someone else owns the outcome rather than software you operate.

Where TaxJar fits

TaxJar is priced off order volume, and that single decision tells you most of what you need to know about who it suits. Both published figures, $39 and $99 a month, are the prices at 200 orders a month, and the page says the price scales as monthly order volume rises. TaxJar's own instruction for picking a tier is to calculate your average monthly number of sales, refunds and returns, which is a wider count than most sellers expect: a returns-heavy apparel business and a returns-free software business with the same revenue land in different places. Work that number out before you look at the tiers, because it is the input every other figure depends on.

The real gate between the two plans is not price, it is API access. Starter allows up to 3 data import integrations and lists no API access at all, so it is a reporting and filing tool that reads your channels after the fact. Professional allows 10 total unique data import and API integrations, with increased API calls per minute at 10,000 and a developer sandbox, which is what you need to calculate tax at checkout in a custom or headless storefront. If real-time calculation is a requirement, your comparison starts at $99 a month and the $39 tier is irrelevant to you.

Filing is a second currency, and it is the part buyers underestimate. Returns go out through AutoFile and each filing consumes a credit. Starter includes 2 free credits a year, Professional includes 4, and beyond that credits cost $50 each on Starter and $55 each on Professional. Count your registered states, multiply by filing frequency, and price those credits as their own line. A seller registered in a dozen states filing monthly buys far more in credits than in subscription, and no tier change fixes that.

Peak months are handled commercially rather than structurally. TaxJar says a high-sales month can temporarily move you to a higher tier through a flex fee, you pay only for the extra volume, and the account returns to the original plan the following month. For a business whose November looks nothing like its February, that beats sizing the contract for the spike all year. The catch is that the flex fee rate is not published, so the month that costs most is the one month you cannot model from the page.

The feature floor is higher than the price suggests, and most of it sits on both tiers: the product tax code catalog, AI-driven taxability recommendations, exemption certificate storage, an address validation API, the economic nexus checker with its dashboard and alerts, notice management and resolution, audit support, overdue and amended returns, and jurisdiction-level reporting. TaxJar says it covers 11,000 jurisdictions and integrates with platforms including Amazon, Shopify and Woo. What Professional adds beyond the API is phone support, a dedicated onboarding specialist, a Customer Success Manager and up to 10 team users. One more thing belongs in the fit decision: TaxJar is a Stripe product, and its own pricing page tells Stripe customers that Stripe Tax might suit them better. Ask which of the two you are being sold.

TaxJar pricing

TaxJar publishes prices, and the figures are specific. Checked on 16 October 2026, Starter is $39 a month and Professional is $99 a month, each shown at 200 orders a month, and the page says the price scales with monthly order volume above that. Annual billing is published only as a relative saving of 10% or more, with no annual figure shown. Two things are deliberately absent: the price at your actual order volume, and the flex fee rate for a peak month. One warning on the page's own structured data, since quotes of it circulate: each plan carries a ceiling figure that reflects the top of the volume range, not a plan price, so do not treat it as one.

What TaxJar publishes

Starter: $39 / mo at 200 orders a month (Monthly, by order volume. Annual billing saves 10% or more)Up to 3 data import integrations, simple and advanced CSV import, economic nexus checker with dashboard and alerts, email support with a guaranteed response time, 2 AutoFile credits a year with additional credits at $50. No API access.
Professional: $99 / mo at 200 orders a month (Monthly, by order volume. Annual billing saves 10% or more)Up to 10 total unique data import and API integrations, API access with increased calls per minute at 10,000 and a developer sandbox, email and phone support with a guaranteed response time, dedicated onboarding support and a Customer Success Manager, up to 10 team users, 4 AutoFile credits a year with additional credits at $55.

Figures as published on the TaxJar pricing page and checked on 16 October 2026. Both are the 200 orders a month prices. Starter can be started from the free trial; Professional is listed with a contact sales action rather than a self-serve path.

Four things decide what you pay, and only one of them is on the page as a number.

Your real order volume, counted TaxJar's way. The published prices are both the 200 orders a month figures, and the page says the tier is set by your average monthly number of sales, refunds and returns. Ask sales for the figure at your own count before comparing TaxJar with anything, and ask where the tier boundaries sit so you know how close you are to the next one.
How many filings you buy. AutoFile credits are the filing meter: 2 a year included on Starter, 4 on Professional, then $50 or $55 each depending on plan. Your registered states and their filing frequencies give you the annual credit count, and that number often exceeds the subscription. Ask whether unused credits roll over and what a credit covers when a return is amended.
The flex fee, which is the only unpublished figure that can surprise you. TaxJar describes temporarily moving to a higher tier in a high-sales month, paying for the extra volume, and dropping back the following month. Get the rate in writing, along with the volume threshold that triggers it, before Black Friday rather than after it.
Whether you need the API. Starter lists no API access, so if tax has to be calculated at checkout or a developer needs a sandbox, Professional is the floor and your comparison starts at $99 a month. Ask too whether your required connectors count against the 10 total unique integrations, since data import and API integrations share that allowance.

What costs extra

Additional AutoFile credits beyond the included allowance: $50 each on Starter, $55 each on Professional. Each credit covers one filing.
Flex fees in months above your plan's order volume. TaxJar describes the mechanism on the pricing page and publishes no rate for it.
State sales tax registrations, listed as a product on taxjar.com with no published price. If you are entering several new states at once, ask for that quoted separately from the subscription.

Implementation and commercial terms

The rows below are what the TaxJar pricing page confirms as of 16 October 2026. Where a row says nothing is published, that is the finding rather than an invitation to estimate.

Published price: Starter $39 / mo, Professional $99 / mo, both at 200 orders a month
Pricing basis: Monthly order volume, counted as sales plus refunds plus returns
Annual billing: Published as a saving of 10% or more. No annual figure is shown
Filing: AutoFile credits. 2 a year on Starter, 4 on Professional, then $50 or $55 each
Implementation fee: None published. Professional lists dedicated onboarding support and a Customer Success Manager
Free trial: 30 days, no credit card required, cancel at any time
Team users: Up to 10 on Professional. No seat count is published for Starter

Budget TaxJar in two lines. Line one is the subscription at your real order volume, which starts from the published $39 or $99 at 200 orders a month and rises from there, so get the figure for your own count rather than the headline. Line two is filing: count your registered states and filing frequencies, subtract the 2 or 4 included credits, and price the rest at $50 or $55 each. Then carry two unpublished items as risks rather than numbers: the flex fee for peak months, and state registrations if you are expanding. Even with those gaps you can model more of TaxJar before a sales call than you can with most of this category. For the counter-case, Avalara publishes per-state figures that compare cleanly against a per-order model, and Zamp publishes nothing but includes filings in one scoped price.

What TaxJar gives up

You give up everything outside the United States. TaxJar is a US sales tax product: the published plans cover calculation, reporting, filing and remittance across US jurisdictions, with no VAT, GST or Canadian provincial tax layer in either tier. If your roadmap includes selling into the EU or the UK within the contract term, the gap is filled by a second vendor rather than an add-on, which is a reason to look at multi-country coverage now rather than to negotiate harder here.

You give up a predictable filing bill. The subscription is published and filing is a per-credit charge that scales with your registration footprint, so the thing most likely to grow is the thing the contract does not fix. Registering in five more states to stay compliant raises your annual credit spend automatically. Managed-service rivals fold filings into one scoped figure, trading transparency for predictability; TaxJar makes the opposite trade, and you should know which one you prefer before you sign.

You give up the API on the cheaper plan, and the gap is wider than it looks. Starter has no API access and caps you at 3 data import integrations, so it fits a seller whose channels are all standard marketplaces and whose tax is calculated by those channels. The moment you have a custom checkout, a subscription billing system or a headless storefront, you need Professional, and you also start counting connectors against the 10 total unique data import and API integrations rather than treating integrations as free. Map your real connector list against that allowance during evaluation.

You give up one number for the month you care most about. The flex fee is a sensible design and it is unpublished, so your peak-season forecast has a hole in the month when order volume, cash and attention are all at their worst. Ask for the rate and the trigger threshold in writing, and if sales will not commit, plan that month at the higher tier price rather than hoping.

You give up some certainty about the roadmap, because the owner sells a competing product. TaxJar is a Stripe product, and its own pricing page points Stripe customers towards Stripe Tax. That is honest and it is also a signal: if you run Stripe, ask why TaxJar rather than Stripe Tax and get the answer from someone who sells both. If you do not, ask what the development commitment to TaxJar looks like over a multi-year term, and keep Kintsugi and Zamp on the list.

How TaxJar compares

US sales tax tools split on two questions: can you read a price, and who does the filing work. TaxJar publishes a per-order rate card and bills filings as credits. Avalara publishes per-state prices for businesses under a revenue threshold. Kintsugi publishes two of its four plans. Zamp publishes nothing at all and says so deliberately. Every figure below comes from that vendor's own pricing page, checked on 16 October 2026, and anything unpublished is recorded as unpublished rather than estimated.

Tool	Best for	Price	Where it breaks
TaxJar	US multichannel sellers who want a published price and will operate the tool themselves	$39 / mo and $99 / mo, both at 200 orders a month	No VAT or GST, and filings are billed as credits at $50 or $55 each beyond the included allowance
Avalara	Sellers whose cost tracks registered states rather than order volume, with SST enrolment on the table	$79 per state/month or $799 per state/year (Core Compliance)	Published plans stop at the $50M revenue line, above which it is a custom quote
Kintsugi	Teams that want to pay per action rather than per order, with a genuinely free entry plan	Free $0, Starter $75 per action; Scale and Premium quoted	The API, SSO and real-time calculation sit on Premium, which publishes no figure
Zamp	Teams that want registrations, filings and notices owned by the vendor rather than operated in-house	Not published, quote only	No price at all for the paid tiers, so every comparison needs a sales call first

What to test in a TaxJar trial

TaxJar publishes a free 30-day trial with no credit card required and cancellation at any time, so this is a real pilot rather than a demo. Starter can be started from the trial; Professional is listed with a contact sales action, so if the API matters you will need a conversation alongside the self-serve path. Five things to settle in the 30 days.

Count your order volume the way TaxJar counts it, on day one. Pull a representative month of sales, refunds and returns and get one number. Then ask sales for the price at that number rather than at 200 orders a month, and ask where the next tier boundary sits. Everything else is priced off this figure, and getting it wrong is the most common way a sales tax budget misses.
Connect your messiest channel, not your cleanest. Import real data from the platform whose exports you distrust and check what TaxJar does with partial refunds, exchanges, shipping charges and marketplace-facilitated sales someone else already remitted. Starter allows up to 3 data import integrations, so if you run more channels than that, this is where you learn which plan you are on.
Test your hardest SKUs against the product tax code catalog and the AI-driven taxability recommendations. Pick the items your own team has argued about: bundles, digital goods, food, anything with a state-specific exemption. Check the results against the one state you know best. A tool that gets your edge cases wrong at trial gets them wrong at scale.
Run the nexus side forward. Use the economic nexus checker, dashboard and alerts against your real revenue and transaction counts by state, and list the states you are approaching. That list is your AutoFile credit forecast, so multiply it by filing frequency and by $50 or $55 to see the filing line before you commit to the subscription line.
Settle the three unpublished items before you sign. Get the flex fee rate and its trigger threshold in writing. Get a price for state sales tax registrations if you are entering new states. And if you are a Stripe customer, make someone explain why TaxJar rather than Stripe Tax, since the pricing page raises the question itself. Ask for data export rights for your transaction and filing history at the same time.

Frequently asked questions about TaxJar

How much does TaxJar cost?

Checked 16 October 2026, TaxJar publishes two prices: Starter at $39 a month and Professional at $99 a month, both shown at 200 orders a month. The price rises with monthly order volume, and annual billing is advertised as saving 10% or more, so your own figure may be higher.

Is TaxJar free?

No, but the trial is. TaxJar publishes a free 30-day trial with no credit card required and cancellation at any time. There is no permanently free plan: after the trial you are on Starter at $39 a month or Professional at $99 a month, plus filing credits.

How much does TaxJar charge for filing?

Filing runs on AutoFile credits, one per return. Starter includes 2 free credits a year and Professional includes 4. Beyond that, credits cost $50 each on Starter and $55 each on Professional, checked 16 October 2026. Filing monthly in several states costs more than the subscription.

How does TaxJar work?

You connect your sales channels, TaxJar aggregates the orders, applies taxability from its product tax code catalog, and reports your liability by jurisdiction. Returns are then submitted through AutoFile using credits. Professional adds an API so tax is calculated at checkout rather than reported after the sale.

Who bought TaxJar?

TaxJar is a Stripe product. Its own pricing page tells Stripe customers that Stripe Tax might be a good fit, which is worth raising with sales: if you already run Stripe, ask why TaxJar rather than Stripe Tax, and get the answer from someone who sells both.

What is the difference between Starter and Professional?

API access, mostly. Starter allows up to 3 data import integrations and lists no API, so it reports after the sale. Professional allows 10 total unique data import and API integrations, 10,000 API calls a minute, a developer sandbox, phone support, a Customer Success Manager and up to 10 team users.

Does TaxJar cost more during a busy month?

Yes, through flex fees. TaxJar says a high-sales month can temporarily move you to a higher tier, you pay only for the extra volume, and the account returns to your original plan the next month. The flex fee rate itself is not published, so ask for it in writing.

Does TaxJar handle VAT or Canadian sales tax?

No. TaxJar covers US sales tax, which it says spans 11,000 jurisdictions, and neither published plan includes VAT, GST or Canadian provincial taxes. If you sell into the EU, the UK or Canada inside your contract term, plan on a second vendor rather than an add-on.

What audit and notice support is included?

Both published plans list notice management and resolution, audit support, overdue and amended returns, accelerated payment program support and an archive of historical sales tax data. Exemption certificate storage and jurisdiction-level reporting are also listed on both tiers, checked 16 October 2026.

What does a state sales tax registration cost?

No price is published. State sales tax registrations are listed as a product on taxjar.com, with no figure attached as of 16 October 2026. If you are entering several states at once, ask for registrations quoted separately from the subscription and the AutoFile credits.
