GoSystem Tax APIs

Put GST API's to work for you

Integrate GoSystem Tax with the rest of your application tech stack

GoSystem Tax APIs enable you to automate tax workflow processes related to e-Filing, printing, and importing/exporting tax return data. Save time on return filing by letting our solutions import in real time hundreds of partners into a partnership return or update a specific value within the tax return using live APIs.

Implementing GoSystem Tax APIs is as easy as picking from our standard out of the box and ready to go solutions with no developer experience needed. For more complex tax workflows, we offer the ability to customize an API solution that fits your business best.

These endpoints implement a JSON-based messaging structure, which allows for concise, lightning-fast requests to the GoSystem Tax product. The GoSystem Tax APIs have industry leading asynchronous APIs which allows for time consuming requests to process in the background while other requests are made.

Live APIs are currently available for the following tax forms, 990, 1040, 1041, 1065, and 1120.

There are nearly 50+ GoSystem Tax REST APIs available – all of which can be found on the TR Developer Portal.
