When income is taxed both in the source country and in Morocco, double taxation can erode up to 50% of the net gain. Moroccan tax law and bilateral treaties provide three elimination mechanisms: the ordinary credit, the full credit, and exemption with progression. This guide explains each method, provides worked examples, and outlines the 2026 filing requirements.
Why does double taxation occur?
A Moroccan tax resident is liable for tax in Morocco on worldwide income — this applies to individuals with their tax domicile in Morocco and to companies headquartered there. At the same time, the source state withholds tax on income generated within its borders — dividends, interest, royalties, capital gains. Without a corrective mechanism, the same income bears two tax charges.
The bilateral tax treaties signed by Morocco — over 60 to date — and the unilateral provisions of the General Tax Code (CGI) supply the tools to neutralise this overlap.
The three elimination methods
1. Ordinary credit (limited tax credit)
This is the default method under Article 77 of the CGI for personal income tax and Article 2 of most treaties signed by Morocco. The taxpayer deducts from Moroccan tax a credit equal to the foreign tax paid, but the credit cannot exceed the fraction of Moroccan tax attributable to the foreign income.
Formula:
Tax credit = min(Foreign tax ; Moroccan tax x Foreign income / Worldwide income)This cap prevents a high foreign tax rate from reducing the tax due on Moroccan-source income. Any excess foreign tax that cannot be credited is definitively lost — it may not be carried forward or refunded.
2. Full credit (unlimited tax credit)
Less common, this method allows the full foreign tax to be deducted from Moroccan tax, even if the amount exceeds the corresponding fraction. It appears in certain specific treaties, particularly where the source state applies a reduced negotiated withholding rate.
In practice, the full credit only applies if the treaty expressly provides for it. The taxpayer must verify the relevant bilateral agreement before claiming a full credit.
3. Exemption with progression
Under this method, the foreign income is exempt from Moroccan tax but is taken into account to determine the effective rate applicable to other income. This technique is mainly used in OECD-model treaties for employment income and pensions.
In concrete terms, worldwide income (including the exempt foreign income) is used to calculate the average tax rate, which is then applied only to Moroccan-source income. The taxpayer benefits from the exemption while the progressivity of the tax brackets is preserved.
Worked examples
Example 1: Dividends received from France
A Moroccan company receives MAD 100,000 in dividends from a French subsidiary. The French withholding tax (WHT) is 15% under the Morocco-France treaty, i.e. MAD 15,000.
- Moroccan corporate tax on worldwide income: assume an effective rate of 20%
- Corporate tax attributable to French dividends: 100,000 x 20% = MAD 20,000
- Tax credit (ordinary credit): min(15,000 ; 20,000) = MAD 15,000
- Net Moroccan tax on this income: 20,000 - 15,000 = MAD 5,000
The total tax burden is MAD 20,000 (15,000 in France + 5,000 in Morocco), matching the effective Moroccan rate. Double taxation is eliminated.
Example 2: Interest received from Spain
A Moroccan company earns MAD 500,000 in interest from a Spanish company. The Spanish WHT is 10% under the Morocco-Spain treaty, i.e. MAD 50,000.
- Moroccan corporate tax on worldwide income at 20%
- Corporate tax on Spanish interest: 500,000 x 20% = MAD 100,000
- Tax credit: min(50,000 ; 100,000) = MAD 50,000
- Net Moroccan tax: 100,000 - 50,000 = MAD 50,000
The overall burden reaches MAD 100,000, in line with the Moroccan rate. The Spanish tax is fully recovered as it falls below the cap.
Filing requirements
To claim the tax credit, the taxpayer must follow a precise procedure during the annual tax return:
-
Tax return package: report foreign-source income in the fiscal result declaration (corporate or personal income tax form as applicable), incorporating it into worldwide income.
-
Deductions schedule: enter the foreign tax credit in the extra-accounting deductions table, indicating the source country, the type of income, the gross amount, and the withholding amount.
-
Mandatory supporting documents:
- Withholding tax certificate issued by the foreign tax authority or the foreign debtor
- Moroccan tax residency certificate issued by the DGI (form ADP010)
- Copy of the applicable tax treaty, where relevant
-
Deadlines: supporting documents must be available at the time of filing. In case of an audit, the tax authority may require sworn translations of foreign documents.
Special cases to watch
- Multi-country income: when income comes from several countries, the tax credit is computed on a country-by-country basis, not globally.
- Tax havens: income from non-cooperative jurisdictions may be excluded from the tax credit benefit.
- Transparent entities: for partnerships and similar pass-through entities, the tax credit is allocated to partners in proportion to their share.
