SaaS Platform Development & Integration for Tax Compliance

A cloud-based SaaS platform must be developed, configured, and integrated to fully automate the generation of IRS Form 1042-S, accurate tax withholding calculations, and secure electronic submission to the IRS. The solution must seamlessly connect with existing university financial systems via APIs to pull payroll, stipend, and foreign national data, ensuring real-time compliance and minimizing manual intervention. The platform must support multi-year tax cycles, handle complex international tax treaties, and maintain audit trails for all transactions and adjustments. The contractor is responsible for building a scalable, secure, and compliant system that meets federal tax reporting standards and integrates with the university’s current infrastructure without disrupting financial operations. The project is issued as a subcontract under NAICS code 518210 by the Mississippi Department of Finance and Administration, with proposals due by August 20, 2026. Performance is expected to be fully remote or within Mississippi, with no specified physical location requirements beyond system accessibility and data residency compliance.
