Comoros personal tax domicile reference linking the new 2026 definition to the earlier income-tax framework. Sets out the permanent-home and economic-interests alternatives, identifies the unresolved relationship with the older broader residence tests, and distinguishes domestic domicile from treaty allocation. Describes the baseline arrival and departure provisions with explicit amendment-review limits and points to new tax-clearance requirements for permanent departure. Does not invent a day-count safe harbour or certify historic rate tables as current. Full intervening amendments, treaty applications, numerical liability calculations and independent accountant review remain outstanding.

Article 14 of Finance Law 2026 inserts CGI article 50 bis. It says an individual is fiscally domiciled in Comoros when either of these conditions is met:
The two conditions are alternatives, not a requirement to meet both. The enacted wording on PDF page 14 contains no 183-day threshold. This provision therefore does not support a claim that staying fewer than 183 days automatically prevents Comorian tax domicile. 2026 law, new article 50 bis.
The official 2023 code, article 45 used a broader set of criteria: home or principal stay, local professional activity unless merely ancillary, and centre of economic interests. It also addressed certain state officials serving abroad. The 2026 law adds article 50 bis; the text inspected does not expressly rewrite article 45 in the same passage.
Consequently, this draft does not assert that every older criterion has been repealed, or that a person failing the two new criteria is necessarily nonresident. A legible consolidated text, intervening amendments and authoritative interpretation are needed for that boundary. This is a specific unresolved legal interaction, not a reason to substitute a mainland French residence rule.
Practical evidence includes the availability and use of a permanent home, business and investment locations, and the economic facts supporting the claimed centre of interests. Travel records can help establish facts, but they do not create a statutory day-count exemption absent a rule providing one.
Article 44 of the 2023 code defines global net income by reference to salary/pension, investment, property, business and professional categories. Article 45 subjects fiscally domiciled individuals to IRPP, and nonresidents to Comorian-source income, subject to its treaty and exemption qualifications. It also addresses income allocated to Comoros by a double-tax agreement. These are the baseline provisions to reconcile with the 2026 definition, not proof that every receipt is taxable at one rate. 2023 code, articles 44–49.
Determine the income category and source separately from domicile. A domestic residence finding does not itself decide the outcome under a particular treaty. No treaty tie-breaker or treaty exemption has been verified in this initial Guide.
Article 123 of the 2023 code starts income brought into charge by the move to Comoros from the date domicile is established. It extends the same rule to acquiring a habitual residence where none existed previously. It does not say all income for the entire arrival year is automatically included. 2023 code, article 123.
Article 124's departure framework covers income available before departure, business profits since the last taxed period and specified accrued income. It calls for a provisional declaration at least thirty days before expected departure, absent force majeure, and permits completion within the first three months of the following year. These older procedural provisions still need a complete 2024–2026 amendment check before a departure filing is finalised. 2023 code, article 124.
The 2026 addition to LPF L.4 ter expressly lists a tax-regularity attestation for immigration services before the boarding authorisation of a fiscally domiciled person leaving permanently. L.4 bis and L.4 ter distinguish one-month quitus and three-month attestation validity. Their application and substitution need to be checked with current instructions; do not assume an expired certificate remains usable simply because tax was previously paid. 2026 law, page 13.
Checked 22 October 2026. Resolve article 45 versus new article 50 bis, complete the intervening amendment audit, establish treaty outcomes and obtain current departure forms and clearance instructions. Historic personal-tax bands are deliberately not certified as 2026 rates here. No independent accountant review has occurred. This is a source-cited domicile topic, not full personal-tax or comprehensive country coverage.
