Tax residency
- Residency rules
- Fiscal domicile follows CGI art. 45: home or principal place of stay, main professional activity in the Comoros (unless clearly ancillary), or centre of economic interests. Comorian state officials posted abroad without foreign tax may also be domiciled. There is no standalone 183-day statutory test; long physical presence may support “principal place of stay” but is not the sole criterion.
- Exit tax
- No
- CFC rules
- No
