## Ethiopian Fiscal Architecture

Compliance with Ethiopian Revenue & Customs Authority (ERCA) Proclamation 979/2016 and Regulation 410/2017 demands precise algebraic computation:

### Progressive Income Tax Matrix

- **0 - 600 ETB**: 0% Exempt
- **601 - 1,650 ETB**: 10% (Deduction: 60 ETB)
- **1,651 - 3,200 ETB**: 15% (Deduction: 142.50 ETB)
- **3,201 - 5,250 ETB**: 20% (Deduction: 302.50 ETB)
- **5,251 - 7,800 ETB**: 25% (Deduction: 565 ETB)
- **7,801 - 10,900 ETB**: 30% (Deduction: 955 ETB)
- **Over 10,900 ETB**: 35% (Deduction: 1,500 ETB)
