Double Taxation Agreements (DTAs)
A Lesson Context
With businesses operating across borders, income can be taxed twice: once in the country where it is earned (Source) and again in the country where the earner lives (Residence). Double Taxation Agreements (DTAs) prevent this discouragement of trade.
B Legislative Framework
Section 91 of the Income Tax Act empowers the President to sign agreements with other states to relieve double taxation.
These treaties override the Domestic Act in case of conflict (typically offering a more favorable position to the taxpayer).
C Key Treaty Partners
Zimbabwe has treaties with several nations. Key examples include:
- South Africa
- United Kingdom
- Botswana
- Mauritius
- Netherlands
- China
- France
Note: If no treaty exists, "Unilateral Relief" applies (you can deduct the foreign tax as an expense). If a treaty exists, you get a "Foreign Tax Credit".
D The Credit Method
Zimbabwe uses the Credit Method. You calculate your tax in Zimbabwe on the global income, then subtract the foreign tax paid.
The Formula
1. The Foreign Tax actually paid.
2. The Zimbabwe Tax attributable to that foreign income.
Example
Mrs. Moyo (Zim Resident) earns $100,000 gross fees from a contract in South Africa. SA charges 15% Withholding Tax ($15,000).
Step 1: Zim Tax on $100,000
Assume 25% rate = $25,000.
Step 2: Compare
Foreign Tax ($15,000) vs Zim Tax ($25,000).
Step 3: Relief
The lower amount is $15,000.
Net Payable to ZIMRA: $25,000 (Gross Liability) - $15,000 (Credit) = $10,000.
E Case Law Integration
Treaty Override: The court confirmed that DTA provisions generally take precedence over the domestic Income Tax Act. If the DTA says "pensions are only taxable in the country of residence", the source country cannot tax them, even if its local law says so.
F Common Pitfalls
No "Refunds"
If Foreign Tax ($30,000) is higher than Zim Tax ($25,000), your credit is limited to $25,000. You pay $0 to ZIMRA, but you do NOT get a $5,000 refund for the excess foreign tax.
Proof of Payment
You must prove you actually paid the foreign tax to claim the credit. A certificate or tax receipt is required.
G Knowledge Check
Q1: A Zimbabwean company pays Management Fees to a UK company. The domestic WHT rate is 15%. The UK-Zim DTA limits WHT to 10% for technical fees. What rate applies?
Q2: Can you claim credit for foreign tax if there is NO treaty with that country?
Q3: Is the foreign tax credit ever greater than the Zimbabwe tax liability on that income?
Attempt these before checking the answers below.
H Quiz Answers & Explanations
A1: 10%. The DTA rate overrides the domestic rate if it is lower (more favorable). *Note: Technical fees classification can be complex.*
A2: No (Credit Method). Without a DTA, you usually fall back to "Unilateral Relief" (S17 Deduction), where the foreign tax is a deductible expense, not a full tax credit.
A3: No. The relief is capped at the Zimbabwean tax attributable to that income.
I Key Takeaways
- Purpose: Avoid double taxation and encourage trade.
- Credit Method: The standard relief mechanism in Zimbabwe.
- Override: Treaties trump domestic law.
- No Refunds: Foreign tax credits cannot create a tax refund.
