Volcanic Islands of Perfume, Spice & Ancient Traditions
Comoros primarily taxes Comoros-source income, and residents on income arising in the country. It does not operate an aggressive worldwide-taxation-and-enforcement system for foreigners. However, if you remain tax-resident in another country, that country's worldwide rules may still apply to you.
No — Comoros uses a consumption tax (TC, around 10%) rather than a full credit-invoice VAT, so input-tax recovery is limited compared with European VAT systems.
The standard corporate profits tax is in the region of 35%, with minimum lump-sum taxes possible for low-profit companies. Confirm the current rate and any sector incentives with the DGID.
Its treaty network is very limited. Do not assume treaty relief — most foreigners rely on their home country's foreign tax credit or exemption rules instead.
In Comorian francs (KMF), which are pegged to the euro at 491.96775 KMF = 1 EUR, so euro-equivalent values are stable.
Care is basic. El-Maarouf National Hospital in Moroni is the main referral center, but specialist care, advanced diagnostics, and complex surgery are largely unavailable. Serious cases are evacuated abroad, so medevac insurance is essential.
A yellow fever certificate is required if you arrive from a country with yellow fever risk. Travel clinics also commonly advise hepatitis A/B, typhoid, routine boosters, and antimalarial precautions, as malaria is present.
Pharmacy stock is inconsistent, especially outside Moroni. Bring a sufficient personal supply in original packaging with a copy of your prescription.
No. Use bottled, boiled, or properly filtered water for drinking and take standard food-and-water precautions to avoid illness.
Rarely and unreliably. Comoros is a cash economy — carry euros and Comorian francs, and treat cards/ATMs as a bonus, not a plan.
No. Power cuts are frequent. A generator or solar backup and a water storage tank make a big difference to daily comfort.
French is essential for administration, business, and most services. Comorian (Shikomori) is the everyday spoken language, and Arabic features in religious life. Learning basic French and Comorian greetings helps enormously.
Violent crime is relatively low and daily life is generally calm. The bigger risks are environmental — an active volcano (Karthala), cyclones in the wet season, and unsafe overloaded inter-island boats — plus limited healthcare.
