TRA Tax Rates and PAYE Brackets in Tanzania
TRA calculates PAYE based on progressive tax rates. The current 2025/2026 PAYE brackets are as follows:
| Monthly Income (TZS) | Tax Rate |
|---|---|
| 0 – 270,000 | 0% |
| 270,001 – 520,000 | 8% |
| 520,001 – 760,000 | 20% |
| 760,001 – 1,040,000 | 25% |
| Above 1,040,000 | 30% |
PAYE is calculated on taxable income, which includes salary plus taxable allowances.
NSSF & Other Salary Deductions
Employees and employers contribute to the National Social Security Fund (NSSF). Typical contributions are:
Contribution Type Employee (%) Employer (%) NSSF 10% 10%
Other deductions may include:
- Pension schemes
- Loan repayments (if applicable)
- Cooperative contributions
The TRA Calculator automatically deducts these when computing net salary.
Understanding Your Net Salary
Net salary is the amount you take home after deducting:
- PAYE tax
- NSSF contributions
- Other statutory deductions
Gross salary = Basic salary + Allowances
Net salary = Gross salary – Total deductions
The TRA Calculator provides a clear breakdown, showing how each deduction is applied.
TRA Calculator Example
Suppose an employee earns TZS 1,100,000/month and has housing allowance of TZS 70,000.
- Gross income = 1,100,000 + 70,000 = 1,170,000 TZS
- PAYE calculation:
- 250,000 × 0% = 0
- 270,000 × 8% = 21,600
- 280,000 × 20% = 56,000
- 130,000 × 25% = 32,500
- 240,000 × 30% = 72,000
- Total PAYE = 182,100 TZS
- NSSF: 10% employee contribution = 117,000 TZS
- Net salary = 1,170,000 – 182,100 – 117,000 = 870,900 TZS
This breakdown is exactly what the TRA Calculator provides automatically.
