Congo-Brazzaville Investment Income Guide 2026

Overview — Investment Income Taxation

Congo-Brazzaville taxes investment income through withholding taxes at source for most passive income streams. The withholding tax is generally a final tax for resident individuals, meaning no further tax reporting is required. For companies, withheld tax is creditable against corporate tax. For non-residents, withholding tax rates may be reduced under applicable double tax treaties (including CEMAC regional treaties and bilateral DTTs with France). The Direction Générale des Impôts (DGI) administers all withholding tax under the General Tax Code. The investment landscape includes government bonds (BTA, OTA), bank deposits, listed shares on BVMAC, and private equity.

Dividends — 15% WHT (Final for Residents)

Dividends paid by Congo-Brazzaville-resident companies are subject to withholding tax at 15% for resident shareholders. This is a final tax for resident individuals, meaning the dividend income is not included in the individual's progressive IRPP assessment. For corporate shareholders, the 15% WHT is a creditable advance payment against their CIT liability. For non-residents, the dividend WHT rate is generally 15% (reduced to 10% under the France-Congo DTT and potentially lower under other treaty arrangements). Qualifying dividends from companies listed on the BVMAC may benefit from reduced rates under CEMAC directives. Dividend distributions from Congolese subsidiaries to foreign parent companies are subject to the standard withholding tax unless treaty relief is obtained.

Interest Income — 15% WHT

Interest income is subject to withholding tax at 15% for most sources:

• Government bonds (BTA, OTA) — 15% final WHT for individuals
• Bank deposit interest — 15% WHT (non-final for individuals earning above certain thresholds; must be included in IRPP return with credit for WHT)
• Corporate bonds — 15% WHT on interest payments
• Savings accounts — interest on regulated savings accounts may be exempt up to XAF 500,000 per year

The 15% rate on government bonds makes them relatively tax-efficient for individual investors compared to the top IRPP marginal rate of 45%. Interest paid to non-residents is subject to 15% WHT, which may be reduced under applicable DTTs.

Royalties — 20% WHT

Royalties paid for the use of intellectual property, patents, trademarks, copyrights, and know-how in Congo-Brazzaville are subject to withholding tax at 20% for non-residents. For resident recipients, royalty income is included in ordinary income and taxed at progressive IRPP rates (with a credit for any WHT deducted). Treaty relief may reduce the WHT rate on royalties — for example, under the France-Congo DTT the rate may be reduced to 10%. The payer of the royalty must withhold the tax and remit it to DGI within 15 days of payment. Proper documentation of the intellectual property rights and the royalty agreement is essential for claiming treaty benefits.

Capital Gains — Separate Rates

As detailed in the capital gains guide, gains from investment disposals in Congo-Brazzaville are taxed at specific rates: 10% on real property gains and 7% on securities gains for individuals. These are final taxes, separate from the progressive IRPP schedule. Government securities (bonds, T-bills) held to maturity do not give rise to a capital gain (discount is treated as interest, subject to 15% WHT). For companies, all capital gains are included in taxable profit at the applicable CIT rate.

Regional CEMAC Harmonisation

Congo-Brazzaville is a member of the CEMAC (Communauté Économique et Monétaire de l'Afrique Centrale) region, which includes Cameroon, Central African Republic, Chad, Gabon, and Equatorial Guinea. CEMAC directives harmonise certain aspects of investment income taxation:

• Common withholding tax rates on dividends and interest across the region
• Recognition of the BVMAC as the regional stock exchange
• Common rules for the taxation of collective investment schemes (OPCVM)
• Harmonised tax treatment of regional government securities

Investment income earned by residents of other CEMAC countries is generally subject to the same withholding tax rates as domestic investors, with no further withholding on cross-border payments within the region for certain instruments.

FAQs

Do I need to report dividend income on my tax return?

If you are a resident individual, the 15% WHT on dividends is final, so no further reporting is needed. Non-residents and corporate shareholders should report and claim treaty relief where applicable.

Are foreign investment income and capital gains taxable in Congo-Brazzaville?

Yes, tax residents are taxed on worldwide investment income. Foreign dividends, interest, and capital gains should be declared in the annual IRPP return. Foreign tax credits may be available under DTTs or unilateral relief provisions.

Can I claim a refund if WHT exceeds my tax liability?

Yes, where the WHT deducted exceeds the final tax liability, you can claim a refund from DGI by filing an annual return. This commonly applies to low-income individuals whose total income falls below the taxable threshold.
