Description

The Internal Revenue Service (IRS) is conducting market research for a cloud-based tax calculator software solution, known as the Joint Enterprise Tax Calculator Solution (JETCS). This solution must support standard Application Programming Interface (API) architectures for secure integration with high-volume, complex, and multi-user IRS workflows. Key objectives include obtaining a FedRAMP compliant cloud-based solution that automates tax calculations, generates reports for income tax examinations, and integrates seamlessly with IRS IT systems. The solution should accommodate evolving taxpayer needs and changes in tax laws. The software must be cloud-based, capable of computing tax, interest, and penalties, and integrate with IRS systems, potentially through vendor middleware. It needs to support a 10-year rolling tax window, adhere to IRS performance benchmarks (99% uptime, 10-second API response time), and include a user interface for viewing and editing returns. The solution must also comply with federal security standards such as NIST, FISMA, and FIPS, and support obtaining an Authority to Operate (ATO). The IRS is interested in vendors who can provide tax calculation services, including maintaining the software, incorporating legislative updates, and providing API licensing for enterprise-wide use. The period of performance is expected to include a 12-month base period and four 12-month option periods.
