Tanzania Corporate Income Tax Calculator

Corporate income tax in Tanzania

Tanzanian companies pay corporate income tax at 30% of taxable profit. There are two important reliefs: companies newly listed on the Dar es Salaam Stock Exchange pay 25% for their first three years, and resident SMBs with annual turnover below TZS 100 million can opt for turnover tax at 3% instead of profit tax — which is simpler to compute and often cheaper.

How taxable profit is calculated

Taxable profit = revenue − allowable expenses − capital allowances. Capital allowances replace accounting depreciation: 5% straight-line on buildings, 25–37.5% reducing balance on plant, 50% straight-line on R&D. Tax losses can be carried forward indefinitely subject to the continuity-of-ownership test.

SMB turnover tax — should you opt in?

The 3% turnover tax is a simplified regime open to resident individuals and companies with turnover below TZS 100M. It replaces income tax and the obligation to keep formal accounts — useful if your accounting is informal but typically expensive once your margins exceed ~10%. Use the calculator to compare both methods at your numbers.

Filing & deadlines

• Quarterly provisional tax — by the end of months 3, 6, 9 and 12.
• Annual return — within 6 months of year-end (Form ITX-201).
• Late filing: 5% penalty per month, plus interest at the statutory rate.

Pair this with the VAT Calculator, Withholding Tax and Full Payroll to model your full tax cost. Tawala automates the lot.

Corporate tax is decided by the quality of your books long before the return is filed. Tawala Accounting keeps a clean, auditable ledger through the year — with allowable and disallowable expenses coded as you go — and Tawala Finance shows the tax position monthly rather than as a March surprise.
