Frequently asked questions
Ziptax is purpose-built specifically for sales tax API calculations. Unlike platforms like Stripe Tax or Avalara, which bundle their APIs into large, multi-feature compliance suites, Ziptax focuses only on what many developers actually need: fast, accurate, affordable tax calculation at scale.
Because we aren’t packaging extra filing, reporting, or compliance features into the price, Ziptax is significantly more cost-efficient — often up to 7x cheaper than providers like Stripe Tax for the same volume of API calls.
Ziptax was also built by developers, for developers. That means:
- Direct technical support from the engineers who maintain the API
- No bloated features you don’t need
- Predictable usage-based pricing without surprise fees
No, you won’t be charged when you start.
Every new Ziptax account is automatically enrolled in our Starter Plan. This free plan includes 1,000 API calls per month, which you can use to test the API, validate your workflows, and see how Ziptax fits your business before upgrading to a paid option — no credit card required!
Once you’ve tried the API and understand your expected usage, you can select the plan that fits your needs. Higher-tier plans (like Premium) unlock additional API requests and features — such as product level tax rules, Canadian rate coverage, sales tax holidays, and detailed API logs.
Yes, absolutely. You can upgrade or downgrade your plan anytime directly inside your Ziptax dashboard. Just go to the Billing section of your account and switch plans with a single click. There’s no need to contact our team or wait for support; you’re fully in control of your subscription.
Ziptax offers both monthly and annual billing options.
- Monthly billing lets you pay as you go with maximum flexibility.
- Annual billing is paid upfront for the full year and includes up to 15% savings compared to paying monthly.
Annual plans are especially helpful for businesses with seasonal demand — you get predictable pricing and a lower effective cost while still being able to use more API calls during peak seasons.
When you reach your 1,000 free API calls, you’ll receive an automatic notification prompting you to choose a paid plan so you can continue using the API.
To avoid disruptions to service, we recommend choosing the plan that most closely matches your estimated needs and regularly monitoring your usage either through the API or the Ziptax User Interface.
Ziptax will send alert emails as you approach the upper limits of the calls included with your plan, giving you time to adjust your usage or upgrade before you run out.
If you exceed your included calls, your service will continue without interruption. You will simply begin to incur an overage fee for each additional request beyond your monthly allotment.
Overage rates vary by plan type and the number of included requests, ranging from $0.0242 per call to as low as $0.0011 per call on our highest-tier plans.
Please note that overage fees are only available on paid plans. Free Starter Plan users will need to upgrade to a paid plan to receive additional requests.
