What You Need to Know About Tanzania Corporate Tax

Tanzania's corporate tax rate is a flat 30% on chargeable income, with a relatively new anti-avoidance rule that gives the Commissioner General power to collect withholding tax on undistributed dividends if your company does not distribute profits within 12 months of year-end. You pay through four quarterly instalments and file your annual return (ITX 203.01.E) within six months of year-end. Here is the full picture of how corporate tax works in Tanzania.

1. What is Corporate Tax?

Corporate tax in Tanzania is the income tax charged on the profits of companies doing business in the country. The standard rate is 30% of chargeable income. Companies in the extractive sector (mining, oil, gas) may face different rates. The Tanzania Revenue Authority (TRA) administers corporate tax.

2. Who does it apply to?

This usually applies to:

Companies incorporated in Tanzania (resident companies)
Branches of foreign companies operating in Tanzania
Non-resident companies earning income from Tanzanian sources
Partnerships and trusts (taxed at applicable rates)
Companies in special economic zones (may qualify for incentives)

3. Why does it matter?

Understanding corporate tax helps you:

Stay compliant with tax laws
Avoid penalties and late fees
Keep proper records
File and pay correctly
Plan your cash flow better

4. How does it work?

Here's the basic process:

Register your company with the TRA and obtain a TIN
Maintain proper books of account throughout the financial year
Calculate chargeable income (gross income minus allowable deductions and capital allowances)
Pay instalment tax in four quarterly payments during the year
File your annual income tax return (ITX 203.01.E) within 6 months of your financial year-end
Pay any balance of tax due with the return
The TRA may issue an assessment based on your filing

5. What forms are involved?

ITX 203.01.E - Annual corporate income tax return
Instalment Tax Form - Quarterly instalment payments
Financial Statements - Audited accounts accompanying the annual return
Tax Computation Schedule - Breakdown of chargeable income calculations

6. What information do you need?

Before handling corporate tax, make sure you have:

Your company's TIN
TRA online portal login credentials
Audited financial statements
Schedule of capital allowances (depreciation, initial allowances)
Details of all income sources (domestic and foreign)
Withholding tax certificates received
Prior year tax assessments and payments
Transfer pricing documentation (for related-party transactions)

7. Important deadlines

Filing frequency: Annual return
Payment deadline: Instalment tax in four quarterly payments (by the end of the 3rd, 6th, 9th, and 12th months of the accounting period). Final balance due with the annual return.
Year-end requirements: File the annual return within 6 months of the end of the accounting period, with audited financial statements

8. Common mistakes to avoid

Missing quarterly instalment tax payments, which attract penalties and interest
Not claiming available capital allowances on qualifying assets
Failing to withhold tax on payments to non-residents (dividends at 10%, interest at 10%, royalties at 15%)
Overlooking the TRA's new anti-avoidance rules on undistributed dividends
Not maintaining proper transfer pricing documentation
Underestimating instalment tax, leading to penalties at year-end
Missing the 6-month filing deadline for the annual return

9. Simple example

Your company earns TZS 500,000,000 in revenue and has TZS 350,000,000 in allowable expenses.

Chargeable income: TZS 500,000,000 - TZS 350,000,000 = TZS 150,000,000
Corporate tax at 30%: TZS 150,000,000 x 30% = TZS 45,000,000

Instalment tax payments (quarterly):

Q1 (3rd month): TZS 45,000,000 / 4 = TZS 11,250,000
Q2 (6th month): TZS 11,250,000
Q3 (9th month): TZS 11,250,000
Q4 (12th month): TZS 11,250,000

Any balance or overpayment is settled when filing the annual return.
