The Union of the Comoros is an archipelago nation in the Indian Ocean, situated between the northern tip of Madagascar and the coast of Mozambique. It comprises three main islands: Grande Comore (Ngazidja, site of the active Karthala volcano), Mohéli (Mwali), and Anjouan (Ndzuwani), with the separate island of Mayotte — claimed by Comoros but administered by France as a French overseas department. The Comoros is francophone, with official languages of Comorian (Shikomori), French, and Arabic.
Despite its very small size and population (approximately 900,000), Comoros has attracted international attention through its former Economic Citizenship Programme (historically one of the most notable in the Indian Ocean region, though now discontinued) and its position as a potential financial and maritime services hub in the western Indian Ocean corridor.
Political and Legal Context
Comoros has experienced repeated political instability and coups since independence from France in 1975. President Azali Assoumani has governed since 2019 (and previously from 1999–2006). The legal system reflects French civil law traditions plus Islamic personal law. The islands have historically rotated the presidency among the three islands; constitutional amendments ended this rotation, creating political tension.
The Comorian franc (KMF) is the official currency, pegged to the Euro at KMF 491.97 per EUR — providing exchange rate stability similar to the CFA franc system, though managed through a bilateral arrangement with France rather than the BCEAO/BEAC system.
Economic Citizenship Programme (Discontinued)
Comoros gained international attention through the historic issuance of economic citizenship — selling Comorian passports — which provided a route to a Comorian passport (and potentially visa-free access to certain states) in exchange for investment. The programme, established in 2001, attracted significant interest from stateless persons and investors in the Gulf region in particular. However, it was beset by serious governance and corruption controversies (including the high-profile passport sales scandal) and was discontinued by the Comorian government from 2017; it is not an operational route to citizenship today. Any historic Comorian economic-citizenship documentation should be reviewed carefully with specialist legal advisers.
The Comorian passport has historically provided relatively limited visa-free access compared with programmes in the Caribbean or Europe. Individuals seeking a citizenship-by-investment route for travel-document value should therefore look to established Caribbean CBI programmes rather than to Comoros.
Tax Framework
Comoros levies income tax on locally sourced income. The tax system is relatively underdeveloped:
- Progressive individual income tax applies to employment and business income at rates up to approximately 30%
- Foreign-source income is generally not taxed for residents in practice
- No capital gains tax
- No inheritance tax
- No annual wealth tax
No DTA exists between Comoros and the United Kingdom. British nationals must manage their UK SRT position independently.
UK Pension Implications
No UK-Comoros DTA or reciprocal social security agreement. UK State Pension paid to Comorian residents is frozen. UK private pension income faces UK withholding at source. QROPS arrangements are not available in Comoros.
Banking Environment
Comoros has a very small banking sector. The Banque Centrale des Comores (BCC) regulates commercial banks including Banque de Développement des Comores (BDC) and Exim Bank Comoros. Mobile money (Orange Money) is growing rapidly. The KMF peg to EUR provides stability. For HNW private banking, Comorian residents typically use accounts in France, Mauritius, or the UAE.
Investment Climate
Comoros is primarily an agricultural and fishing economy:
- Vanilla: Comoros is among the world's top vanilla producers
- Ylang-ylang: Used in perfumery (Comoros supplies a significant share of global production)
- Cloves: Agricultural export
- Fisheries: Tuna fisheries in the Indian Ocean
- Tourism: Ecotourism is developing; the islands have exceptional marine life and an active volcano on Grande Comore
The Indian Ocean position of Comoros — between the African coast and Madagascar — creates potential as a maritime services and transhipment hub, though infrastructure limitations constrain this ambition.
Cost of Living
Moroni (the capital on Grande Comore) has a moderate cost of living. Imported goods carry premiums; local food and basic services are affordable. Healthcare infrastructure is very limited; serious medical conditions require evacuation to Mayotte, Réunion, or beyond.
Key Compliance Issues for Expats
Due diligence on citizenship: The former economic citizenship programme attracted significant scrutiny and was discontinued; any historic Comorian citizenship documentation must be subject to thorough legal advice and compliance review before being relied upon.
UK SRT management: British nationals in Comoros must satisfy the SRT to break UK residence. Without a DTA, HMRC retains taxing rights over UK-source income.
AML/KYC: The limited banking infrastructure and governance capacity in Comoros creates elevated AML risk; UK money laundering regulations require appropriate due diligence.
Practical Financial Planning Tips
Caribbean CBI as the credible route: With the Comorian programme discontinued, internationally mobile individuals seeking citizenship by investment should look to established Caribbean CBI programmes (St Kitts, Antigua, Dominica, St Lucia, Grenada — all now with minimum contributions of USD 200,000 or more), which offer superior visa-free access, stronger governance and robust due diligence.
Indian Ocean regional opportunity: Comoros' position in the western Indian Ocean makes it a potential complement to Mauritius or Seychelles-based investment strategies for those with regional African interests.
Agricultural commodities: Vanilla and ylang-ylang are specialist commodity markets with significant price volatility; investment requires specialist agricultural and commodities knowledge.
Infrastructure limitations: Any substantial investment must account for Comoros' very limited physical infrastructure — power, roads, ports, and telecommunications — and budget accordingly for private provision.
Political risk: Periodic political instability is a persistent feature; investment should be structured with this risk in mind, including offshore holding structures and robust exit provisions.
