Cloud-Based Tax Calculator Solution

This request for information seeks vendors capable of providing a cloud-based tax calculator solution. The product may consist of one or more offerings designed specifically for computing audit adjustments and tax based on data provided. It is essential that the solution integrates seamlessly with IRS systems and can map IRS-provided datasets to the vendor’s software to perform accurate computations.

The solution must support a high-volume, multi-user environment suitable for both manual and automated IRS workflows. It should accommodate a 10-year rolling tax window, encompassing the current tax year, and enable single-year, multi-year, and complex multi-form or multi-schedule tax computations, including corrections. Adherence to IRS performance benchmarks is required, including handling peak loads, achieving a 99% uptime target, and delivering API responses within 10 seconds under all conditions.

A user interface is necessary for viewing and editing returns. The application’s lag time should be virtually imperceptible to the end user, never exceeding a 10 second response when processing single-return data.
