Overview
IDRAS is a next-generation solution that integrates every stage of tax administration — registration, filing, payment, audit, and citizen services — into a single system. Through data-driven operation, it simultaneously delivers increased tax revenue and operational transparency.
Designed and built for the Tanzania Revenue Authority (TRA), the system is built on Microservice Architecture (MSA) and AI-based risk analysis. Modules scale independently and adapt flexibly to any nation's tax environment.
Core Domains
Each domain operates independently while sharing data — one continuous flow from taxpayer registration to statistical analysis.
Unified management of all registration activities — taxpayer, motor vehicle, driving license, inventory, and electronic tax invoice.
Taxpayer Motor Vehicle (CMV) Driving License (CDL) Inventory E-Tax InvoiceFrom return submission through automated calculation to exemption handling — the entire filing process managed as a consistent workflow.
Return Filing Assessments Tax Relief & ExemptionsAutomated collection, refunds, and arrears management linked to the government electronic payment gateway. Accounting under GFS standards.
Revenue Collection Refunds Debt & ComplianceAI-driven risk profiling auto-selects audit targets — improving both taxation fairness and evasion detection rates.
Risk Management Risk Profiling Audit InvestigationAll taxpayer touchpoints unified — including legal procedures such as objections, appeals, and rulings, all handled within the system.
Objections & Appeals Private & Class Ruling Communication Knowledge Taxpayer EducationAll system data is aggregated into a Data Warehouse (DW), immediately usable for policy decisions and trend analysis.
