Corporate Income Tax
A Lesson Context
Companies are separate legal entities from their shareholders. In Zimbabwe, companies pay tax on their "Taxable Income" sourced from Zimbabwe. They do not wait until year-end to pay; they pay in advance through Quarterly Payment Dates (QPDs).
B Applicable Tax Rates
General Rate
The standard Corporate Income Tax (CIT) rate is 25%.
AIDS Levy
A surcharge of 3% is calculated on the tax payable (not on the profit!).
Calculation: 25% * 1.03 = 25.75% Effective
Rate.
Special Rates
- Mining Companies: Varies (Often 25% but formula-based for Special Mining Leases).
- Manufacturing Exporters: Reduced rates (e.g., 20% or lower) apply if a company exports significant volume.
C Tax Computation Logic
Taxable Income is NOT the same as Accounting "Net Profit". You must adjust it.
(+) ADD BACK: Prohibited Expenses (Depreciation, Donations, Fines, Entertainment)
(-) LESS: Non-Taxable Income (Dividends from local companies)
(-) LESS: Special Deductions (Capital Allowances)
(=) Taxable Income
Note: Depreciation is an accounting estimate and is disallowed. Instead, ZIMRA grants "Capital Allowances" (SIA, Wear & Tear) based on strict rules.
D Quarterly Payment Dates (QPDs)
S72 of the Income Tax Act requires companies to estimate their annual tax liability and pay in four installments.
| Quarter | Due Date | Percentage Due | Cumulative |
|---|---|---|---|
| 1st (Jan-Mar) | 25 March | 10% | 10% |
| 2nd (Apr-Jun) | 25 June | 25% | 35% |
| 3rd (Jul-Sep) | 25 September | 30% | 65% |
| 4th (Oct-Dec) | 20 December | 35% | 100% |
E Section 80: Withholding Tax on Tenders
To ensure compliance, ZIMRA requires companies paying suppliers ($1000+ per year aggregate) to check if the supplier has a valid Tax Clearance Certificate (ITF 263).
- With Clearance: Pay supplier in full.
- No Clearance: You MUST withhold 30% (verify current rate!) of the payment and remit it to ZIMRA.
Failure to withhold makes the payer liable for the tax plus 100% penalty.
F Case Law Integration
Apportionment Principle: If a company incurs expenses (like detailed audit fees) that relate to both Taxable Income (Trading) and Exempt Income (Dividends), the expense must be apportioned. You can only deduct the portion relating to Taxable Income.
G Common Pitfalls
Missing QPD Estimations
Companies often underestimate their QPDs early in the year to hold onto cash. If the final tax is much higher, ZIMRA charges interest from the date the QPD was due.
Depreciation
Forgetting to add back "Depreciation" and claim "Capital Allowances" instead. This is the most common error in tax computations.
H Knowledge Check
Q1: A company has a Net Profit of $100,000 which includes Depreciation of $10,000. It has no Capital Allowances. What is the Taxable Income?
Q2: When is the 1st QPD payment due?
Q3: You are paying a supplier $2,000. They do not have a tax clearance. How much cash do you pay them (assuming 30% WHT)?
Attempt these before checking the answers below.
I Quiz Answers & Explanations
A1: $110,000. You must add back depreciation ($100k + $10k).
A2: 25 March. It is 10% of the annual estimate.
A3: $1,400. You withhold 30% ($600) and pay it to ZIMRA. You pay the supplier the remaining 70% ($1,400).
J Key Takeaways
- Effective Rate: 25.75% (Base + AIDS Levy).
- QPDs: Essential for cash flow management. Dates are fixed.
- Section 80: Always demand a Tax Clearance Certificate from suppliers.
- Computation: Taxable Income = Profit +/- Adjustments. Depreciation is disallowed.
