Companies operating in Namibia pay corporate income tax on their taxable income. The headline rate has been coming down in phases as part of Namibia's tax reform programme. This guide covers the current rates, how provisional tax payments work, filing deadlines, and recent changes worth knowing.
Current rates
The general rate was 32% until the end of 2023, then reduced to 31% for financial years starting on or after 1 January 2024 and 30% from 1 January 2025, with a further legislated reduction to 28% from the 2026/27 fiscal year.
| Company type | Rate |
|---|---|
| Non-mining companies (financial years from 1 Jan 2025) | 30% |
| Non-mining companies (from 2026/27) | 28% (legislated reduction) |
| Mining companies (non-diamond) | 37.5% |
| Diamond mining | 55% |
Provisional tax: paying as you go
- First provisional payment: due within the first six months of the company's financial year, based on estimated taxable income
- Second provisional payment: due by the end of the financial year, trueing up the estimate
- Final (top-up) payment: any balance is payable when the annual return is assessed
- Underestimating seriously can trigger penalties, so estimates should be grounded in real management accounts
Filing the annual return
Companies file an annual income tax return with NamRA (via the ITAS portal), generally due within seven months of the financial year end. The return is based on annual financial statements, with tax adjustments for non-deductible items, capital allowances and assessed losses.
Recent changes to know
- Dividend tax: a 10% tax on dividends applies from 1 January 2026
- Interest deduction limit: the old 3:1 thin-capitalisation ratio is replaced by a 30%-of-earnings limit on interest deductions
- Assessed losses: carry-forward of assessed losses is now capped rather than indefinite for larger companies
- These reforms accompany the phased rate reductions — worth reviewing with your tax advisor if your structure relies on debt funding or accumulated losses
