Sphere

What Sphere is

Sphere is a paid tax API for businesses handling sales tax, VAT, or GST operations. Its listed capabilities include sales-tax calculation, tax registration, and automated return filing. The service is offered through API access rather than a desktop or mobile application. Sphere lists a Starter plan at $100 a month, billed monthly, for fewer than 10 regions. A Growth plan is listed for 10 or more regions, but its price is not provided. There is no free plan. The API can support programmatic tax workflows covering calculation, registration, and filing. Return filing is marked as automated, while supported tax types are sales tax, VAT, and GST. The plan structure is based on regional coverage, with Starter explicitly limited to fewer than 10 regions. Businesses evaluating Sphere should account for the recurring Starter fee or request pricing for the Growth offering.

Who it suits

Sphere suits businesses that need tax calculation, registration, and return filing through an API. It is aimed at teams integrating tax operations into software rather than using a standalone manual filing application.

Limits
