How the AI is Trained
1
Training data: 3 years of EFRIS transaction records (anonymised), external data sources (UNRA vehicles, URSB property, MoMo transaction volumes via MTN/Airtel API, KCCA business licences)
2
Algorithm: Random Forest classifier for anomaly detection (handles non-linear relationships). LSTM neural net for compliance churn prediction. Linear programming for budget optimisation.
3
Validation: Model retrained monthly on new EFRIS data. Back-tested against known fraud cases. Current accuracy: 94.2% (true positive rate for audit recommendations).
4
Comparable systems: Greece IAPR (hidden pattern detection), India Income Tax AI (charitable donation skew), Australia ATO (audit time reduction 80%), Rwanda MoMo tax engine (UGX equivalent billions captured year 1).

AI Assessment
This scenario is moderately ambitious. With 65% EFRIS compliance, 0.3% MoMo withholding, and 60% audit coverage, Uganda generates an additional UGX 1.87 trillion annually. Debt-to-GDP falls to 47.8% by 2028. This is achievable within 24 months if enforcement begins now.

๐ค Model detected 312 businesses at high risk of going dormant in the next 60 days based on their EFRIS filing patterns. Early intervention (automated SMS + WhatsApp today) is 8x cheaper than re-engaging after they go dormant.

Mobile Money Tax Withholding Model
Revenue projection for automatic 0.3% withholding tax on MoMo transactions above UGX 100K โ the highest ROI intervention available
โ Rwanda precedent: Rwanda implemented MoMo transaction tax and collected equivalent of USD 180 million in year 1 with zero filing burden. Uganda has 3x more mobile money accounts than Rwanda. This is the single highest-ROI fiscal intervention available.

1.0% rate (Kenya model)UGX 2.0T/year (may reduce MoMo usage)
AI recommendation: 0.3% is the optimal rate โ maximises revenue while maintaining MoMo adoption. Kenya's 1.5% rate caused a 30% drop in MoMo usage in 2023. Don't repeat that mistake.

FISCAL INTELLIGENCE BRIEFING โ MAY 2025
Prepared by FiscalAI ยท Classification: CONFIDENTIAL
1. CURRENT FISCAL POSITION
Total public debt stands at UGX 116.2 trillion (51.3% of GDP). Revenue collected in May was UGX 2.24 trillion against a target of UGX 2.41 trillion โ a shortfall of UGX 167 billion. EFRIS compliance rate remains at 48.5%. 127 high-risk anomaly cases have been identified this month representing an estimated UGX 84 billion in at-risk tax revenue.
2. AI-IDENTIFIED PRIORITY ACTIONS
(1) Deploy field investigators to top 24 critical anomaly businesses this month โ estimated recovery UGX 18โ42 billion. (2) Formally propose Mobile Money withholding tax (0.3%) to Parliament for implementation from FY 2026/27 โ projected UGX 600 billion annually. (3) Activate dormant EFRIS re-engagement campaign for 4,821 inactive businesses โ automated SMS has been prepared and can be deployed immediately.
3. DEBT REDUCTION PATHWAY
If all three priority actions above are implemented before December 2025, FiscalAI models project: additional revenue of UGX 660 billion by end of FY 2025/26; debt-to-GDP ratio falling to 49.8% by June 2026; and a trajectory to reach 45% by 2029 โ well within the government's medium-term fiscal framework target.
