TL;DR

TaxJar publishes two self-serve plans and bills filing separately, so the sticker price understates what most companies actually pay. Starter runs $39/month and Professional runs $99/month, and both cover 200 orders/month at the base tier before scaling by volume (support.taxjar.com).

The base plan does not cover the two costs that grow with your footprint. AutoFile is charged per return, and state registration carries a separate fee. Your real cost tracks how many states you file in each month, not the plan you pick.

If you file in a handful of states, the base plan reads cheap. If you file in fifteen or twenty, per-return fees become the dominant line item, and the plan tier barely moves the total.

TaxJar's published pricing tiers

TaxJar sells two published self-serve plans plus a custom enterprise tier. Both published plans cover 200 orders per month at their base price and charge more as your order volume climbs past that threshold. The Starter plan runs $39 per month and Professional runs $99 per month, a recent increase from the $19 Starter that held for years.

The difference between the two plans shows up in support level and included filing credits, not in calculation accuracy. Starter includes 2 AutoFile credits per year. Professional includes 4. Every filing beyond those credits gets billed separately, which the next section breaks down.

TaxJar prices its enterprise tier through sales rather than a public number, so any specific dollar figure you find on third-party sites is unverified. If your volume exceeds the published tiers, you negotiate directly.

Two costs sit outside every plan. State registration runs $299 as a one-time fee per state, charged each time you register in a new jurisdiction. There is no permanent free tier, only a 30-day free trial, so budget for a paid plan from the point you go live.

The sticker price tells you almost nothing about what you will actually pay. A company filing in twelve states pays far more in AutoFile fees than in plan cost, and that arithmetic is where the real number lives.

What's included and what costs extra

Your monthly plan price covers tax calculation and access to AutoFile, but the actual filing of each return costs extra. TaxJar's base subscription buys you the sales tax engine and integration. Every return AutoFile submits carries its own per-filing fee beyond a small annual credit allotment.

AutoFile fees run $50 per return on Starter and $55 per return on Professional, per TaxJar's AutoFile pricing documentation. Both rates rose in the 2026 pricing change, Starter from $30 and Professional from $35. Starter includes 2 AutoFile credits per year and Professional includes 4. Every return past those credits bills at the full per-return rate.

State registration is a separate one-time charge of $299 per state, per TaxJar's plan and pricing documentation. You pay it once when TaxJar registers you with a state's tax authority, and it stacks per state you sell into.

The distinction that trips up buyers is what "files" actually means here. TaxJar calculates what you owe and submits the return, but you remain responsible for the underlying registration decisions and for the money itself flowing to each state on schedule. A fully managed remittance service takes the payment obligation off your plate. TaxJar's model keeps you in the loop as the party accountable for each jurisdiction.

TaxJar's published plans cover AutoFile and state registration. Back-filing and voluntary disclosure agreement services are not listed on TaxJar's pricing page. That absence matters as a coverage gap, not just a line-item you'd pay for elsewhere. Companies that discover past nexus in states where they never collected tax need a VDA to limit back liability, and a platform without that service leaves you to hire an outside advisor or handle the negotiation yourself. If your sales history spans states you registered in late, budget for that work separately.

The 2026 price increase and what it signals

TaxJar raised prices in 2026 for the first time in more than six years, and the increases hit the two costs that matter most. The Starter plan moved from $19 to $39 per month, a straight doubling. AutoFile per-return fees rose from $30 to $50 on Starter and from $35 to $55 on Professional, per TaxJar's AutoFile pricing documentation.

The AutoFile jump matters more than the plan jump because filing fees scale with the number of states you sell into. A company filing in ten states absorbs a 67 percent increase on the largest recurring line in its bill, not just the $20 monthly plan bump. For a multi-state seller, the per-return rate drives total cost far more than the sticker price does.

The timing points back to Stripe, which acquired TaxJar in 2021 for roughly $850 to $900 million, per Axios, and has not raised prices on the product in the years since. Six years without a price change is unusual for a product owned by a company that reprices aggressively across its portfolio. A doubling on the entry tier suggests TaxJar is repositioning away from small self-serve sellers toward accounts that generate more filing revenue.

For existing customers, the direction of travel is clear. The first increase in six years arrived as a doubling rather than a modest adjustment, which sets a precedent for how future changes may land.

Rollout timing depends on your contract type, and TaxJar has not published a single universal effective date. Confirm directly with TaxJar when the new rates apply to your account before budgeting against the old numbers.

Hidden costs mid-market companies run into

The list price tells you almost nothing about what you will pay once you file in more than a handful of states. TaxJar's Starter plan costs $39 per month, but each AutoFile return past the two included yearly credits runs $50, and those fees compound fast for a company filing monthly across many states.

Take a mid-market seller registered in 15 states and filing monthly on the Starter plan. The base plan stays at $39 per month. After the two included AutoFile credits, you pay for the remaining 13 states every month at $50 each, which is $650. That brings the monthly total to $689, or roughly $8,268 per year in filing costs alone. If you register all 15 states through TaxJar's own service, add a one-time $299 per state, or $4,485.

The math scales linearly, so a 20-state filer feels it harder. The base plan holds at $39 per month, and 18 states beyond the included credits cost 18 times $50, or $900 per month. Your monthly total reaches $939, and the annual figure lands near $11,268. Registering all 20 states adds a one-time 20 times $299, or $5,980. All AutoFile and registration figures come from TaxJar's own support documentation, so you can rerun the arithmetic against your own state count.

Reviewers flag the gap between the advertised plan and the real bill. On Capterra, TaxJar holds a 4.4 out of 5 rating from 76 reviews, where buyers weigh the platform against its total cost of ownership rather than the $39 entry price.

The pattern to watch is credit exhaustion. Your two or four annual AutoFile credits cover a single filing period, not a state for the year, so a monthly filer burns through them in the first month and pays per return for everything after. The more states and the more frequent the filing, the wider the distance between sticker price and actual spend.

TaxJar vs. Taxwire vs. other alternatives

The cleanest way to compare TaxJar against its alternatives is to separate the tools that charge per filing from those that fold remittance into the price. TaxJar calculates and files but leaves remittance funding and management largely to you. Taxwire prices per return with remittance included. The table below sets the published figures side by side.

Avalara, Numeral, and Anrok do not publish per-return or per-seat rates, so any figure you find outside their sales teams is an estimate rather than a quote. TaxJar remains the only one of the five with fully published plan and filing rates, which is part of why buyers reach for it first. That transparency is real, and for a small seller it is a fair reason to choose it.

TaxJar is a reasonable fit when you file in a handful of states, run low order volume, and are comfortable managing remittance and support timing yourself. The trouble starts once your filing count climbs, because each AutoFile credit past your included two or four adds $50 to $55 a month, and remittance stays your problem.

Taxwire is built for the point where that math stops working. Six differences drive the case. Remittance is included at no additional charge. Pricing is flat at $100 per return regardless of order volume, so a high-revenue month never inflates your bill. VDA and back-filing support are part of the service rather than a separate engagement. An in-house tax team reviews every return before it files. Support responds in under one hour. There is no order-volume pricing penalty, which is the cost most mid-market sellers underestimate with usage-tiered tools.

If you file in ten or more states monthly and want remittance handled without a per-order surcharge, Taxwire answers the exact gaps TaxJar's published plans leave open.

Who TaxJar's pricing actually works for

TaxJar makes sense for a small seller filing in a handful of states with steady, low order volume. If you sell in two or three states, file monthly, and stay near the 200-order base included in the Starter plan, the $39/month plan plus a couple of AutoFile credits keeps your annual cost predictable and low.

The self-serve model also fits companies that can tolerate support delays. TaxJar answers tickets on its own timeline, so if you have someone in-house who understands sales tax and can wait a day or two for a reply, the DIY structure works.

Where the fit breaks down is filing scale. Every state past your two included AutoFile credits adds $50 per return, so a company filing in ten or more states watches the per-filing math outrun the sticker price fast. If you expect to add states, cross the order-volume tiers, or need back-filing and voluntary disclosure work, TaxJar's published plans stop covering what you actually need.
