Ziptax vs TaxJar API

A faster, affordable alternative to TaxJar

Sales tax APIs should have accurate rates, predictable pricing, and responsive support. However, because TaxJar is set up as a full compliance suite, businesses end up paying more for a bundle of features that aren’t always useful. Ziptax strips away the extra and focuses on what developers actually need, including address-level accuracy, transparent pricing, and a free plan to help you get started.

Save hundreds every month with Ziptax

Costs add up fast. While TaxJar ties API calls and transaction volumes together, for complicated, order-based pricing plans, Ziptax’s simple pricing tiers are based only on total API calls.  

The table below features monthly savings, but it doesn’t include additional fees from TaxJar. For example, state registration with TaxJar is a separate $299 fee, which isn’t included in any plan but is required if you intend to remit taxes in a new state with TaxJar (also billed separately).

Why go with Ziptax?

Affordable pricing and API-focused development

Bundled filing, nexus tracking, and filing services are built into TaxJar pricing, but many developers don’t need those features when trying to calculate taxes.

Rather than paying for a sprawling platform, Ziptax delivers a lightweight API built for developers who want clean data and low-cost tax calculations.

With Ziptax, you’ll only pay for sales tax calculations. Filing, nexus tracking, and other features can be handled by our partner TaxCloud, which integrates seamlessly with the Ziptax API.

Free to start

With Ziptax, you don’t need to pay in order to test or develop your configurations.

Ziptax’s Starter plan includes 1,000 free API calls every month, so your team can validate integrations, run pilot programs, and cover light usage without ever opening your wallet.

If you’re just starting out, it’s a fast and easy way to calculate accurate sales tax at no charge. When you’re ready to scale, paid plans allow you to increase transactions without breaking the bank or losing a percentage of your profits to transaction fees.

Clear, adjustable plans

TaxJar ties order usage to order volume and states that API calls count for 1/10th of a transaction. Because both API usage and transaction volumes are linked, it’s easy to lose track of total costs or estimate overall usage.

With Ziptax, usage is based on clear, flat-rate call pricing. As volume grows, teams can upgrade to the next tier without the extra guesswork.

What you get with Ziptax

Flexible and lightweight

Ziptax is built for speed and simplicity with an API-first development mindset. Teams can integrate our lightweight API in minutes without extra setup or complicated dependencies and integrations.

Ziptax allows you to upgrade your plan tier easily from a handful of calls to millions per month, so teams don’t need to rebuild or renegotiate contracts as volume increases.

Low cost accuracy

Ziptax delivers pinpoint accuracy, down to the street level. This includes tricky cases like unincorporated areas and overlapping special tax districts where zip code lookups often fail.

Plus, because pricing is call-based, brands can enjoy this level of detail without inflated costs.

Expert support

With Ziptax, you’ll have fast support from experts who can help.

In addition to browsing our extensive documentation, Enterprise plan subscribers can hop into a dedicated Slack channel and chat with our team for quick answers during critical operations. It’s fast, friendly support without long wait times or an email-only ticketing system.

Frequently asked questions

Is Ziptax cheaper than TaxJar?

Yes. At every tier, Ziptax costs less than TaxJar.

  • TaxJar: Between $849 and $2,199/month, depending on volume of orders vs. calls.
  • Ziptax: Always $349/month.

TaxJar combines API calls with transactions, which creates complications and confusion when trying to accommodate needs.

In TaxJar, an API call counts for 1/10th of a transaction. So, in order to have the option of 100,000 calls, you may need to be on the Professional Plan at the 10,000 orders tier.

Orders transacted through a TaxJar integration also deduct from the total number of available calls by a factor of ten. Put another way: For every sale or transaction that comes through with TaxJar, you’ll lose 10 calls.

Combined with flex fees, Autofile fees, third-party processors, and minimum commitment fees, TaxJar is both antiquated and inflexible when compared to Ziptax’s modern and streamlined solution.

With Ziptax, call usage is straightforward. Teams are only paying for API calls. Transactions take place using the API — not a separate integration or connector — meaning that overall costs are lower by default.

How do Ziptax plans compare to TaxJar plans?

Because the allotments for transactions and API usages are combined, TaxJar users must constantly monitor plans for overages through multiple channels.

Ziptax streamlines everything through API calls, so costs are much lower and limits are much easier to parse.

Does Ziptax really have a free plan?

Yes. Our Starter Plan is free forever and offers 1,000 monthly API calls. No credit card is required, and the plan doesn’t expire.

However, unlike our paid plans, the Starter Plan doesn’t include overages or add-ons, meaning that 1,000 calls is a hard limit that refreshes on a monthly basis.

Is a contract required when using Ziptax?

No. While annual plans are available, Ziptax offers flexible, month-to-month plans that can be adjusted based on volume and usage.

We recommend selecting a plan that matches your average monthly volume. If you exceed that plan during peak seasons, overages and add-ons can be purchased to cover that usage.

How do add-ons and overages work with Zip Tax?

Ziptax plans feature a set number of calls per month, while overages cover the difference if the plan limit is reached.

Overages with Ziptax have a pre-set cost determined by the plan tier, with more expensive plans enjoying lower overage costs. For example, an overage on our lowest plan (Growth Plan 1,500) is $0.0242/call. On our highest monthly tier (Growth Plan 250,000), overage calls drop to $0.0034/call.

Ultimately, teams will need to pick the plant that works best for them. Because plans can be changed month over month, we recommend picking a plan based on historical data and then upgrading to the next tier if you’re experiencing constant overages.

Can Ziptax handle state registration or filing?

No. Ziptax is focused on delivering lightning-fast and highly accurate sales tax calculations.

Teams who need assistance with filing and registrations, or who are looking for tools like nexus tracking and product code designations will need to acquire those services from other brands.

However, companies like our partner TaxCloud can import the data from the Ziptax API and use it for filing, remittance, and nexus tracking. It’s a two-part solution that, on average, comes out to a lower cost than what many all-in-one solutions provide.

Can Ziptax keep up if my business grows quickly?

Yes!

Our plans are highly flexible and offer competitive pricing without cutting deeply into your profits with caveats like per-transaction fees or percentage-based cost deductions.

If your business grows quickly, it’s easy to upgrade to another plan. Our annual tiers (pre-Enterprise) climb as high as 3 million calls per month, while enterprise solutions can top 60 million calls per month.
