Industry Focus and Scope
The Client, a national tax authority in Kenya’s public sector, was tasked with administering the country’s tax systems, collecting revenue, and safeguarding taxpayer data on behalf of the state. Responsible for revenue collection across a quickly digitizing economy, the Client saw an opportunity to open their tax systems to the wider economy, allowing for filing, verifications and transactions in real time. To support this vision, Abacus deployed a Sovereign Google Cloud foundation where the core control, security, and intelligence remained local.
The Challenge: Data Sovereignty versus a Digital Tax Economy
The Client faced a digital deadlock. To improve tax collection and curb evasion, while meeting aggressive revenue goals, Kenya’s tax systems needed to open up to the economy, whilst simultaneously maintaining strict Kenyan data sovereignty laws. They needed to modernize filing and real-time verification, leveraging Google Cloud, Agentic Automation, and AI-powered workflows, without compromising data residency.
Key Challenges
Opening Legacy Tax Systems: Tax systems needed to open securely to the wider economy to improve tax collection and curb evasion
Meeting Aggressive Revenue Goals: The platform was expected to support ambitious national revenue targets
Preserving Data Sovereignty: Strict Kenyan data sovereignty laws required that taxpayer data never leave Kenyan borders
Modernizing Filing and Verification: Legacy filing and verification processes needed to be modernized using Google Cloud, Agentic Automation and AI-powered workflows
The Solution: Gava Connect, a Sovereign, Agentic AI-Ready API Cloud Led by Abacus
Abacus resolved the deadlock by architecting Gava Connect, a sovereign API cloud built on Apigee Hybrid, with Agentic and AI capabilities baked into its fabric to make it future-proof.
