Tax in Martinique

Who is the tax authority?

The Direction generale des Finances publiques (DGFiP) administers Martinique's tax affairs, the same agency that covers metropolitan France. Martinique is a French departement — not a territory with a local tax administration. All filings run through impots.gouv.fr.

The DGFiP office for Martinique is the Direction departementale des Finances publiques de la Martinique (DDFiP 972). It handles local assessments, audits, and enforcement. The legal code base is the Code general des impots (CGI) applied directly, with DOM-specific adjustments authorised under the Loi pour le Developpement Economique des Outre-Mer (LODEOM) and related instruments.

Customs, including Octroi de Mer collection, falls under the Direction regionale des douanes et droits indirects (DRDDI Martinique).

What is the tax year and when are returns due?

Martinique follows the French calendar tax year (1 January to 31 December). The prelevement a la source system withholds income tax at source monthly for employees, the same as in metropolitan France.

The annual declaration de revenus (Form 2042 family) reconciles withheld amounts against final tax. Online submissions are staggered by departement group — Martinique (departement 972) falls in a later filing window, typically closing in early-to-mid June.

Corporate impot sur les societes (IS) returns are due within three months of the fiscal year-end. TVA returns are filed monthly or quarterly depending on the regime.

Who counts as a Martinique tax resident?

Martinique is a French departement — residency is determined under the same Article 4 B CGI rules that apply in metropolitan France. An individual is French tax-resident if any one of four criteria is met: their household (foyer) or main residence is in Martinique or mainland France; their main professional activity is there; or the centre of their economic interests is there.

Residents pay tax on worldwide income. Non-residents pay tax only on French-source income. Martinique residents file the same Form 2042 as mainland residents and qualify under all French bilateral double-taxation conventions.

Significant diaspora flows exist: roughly 300,000 Martiniquais live in metropolitan France. Families circulating between the DOM and the mainland need to identify their foyer fiscal carefully — the place of genuine permanent household, not the place of latest posting, governs residence.

What are the personal income tax rates?

Martinique uses the metropolitan French impot sur le revenu bracket schedule without change. The DOM-specific advantage is a 30% reduction on the first EUR 5,100 of tax computed, capped at that amount.

The 30% DOM credit acts like a rebate on the first slice of tax liability — useful for middle-income households. High earners exhaust the EUR 5,100 cap quickly; the top marginal rate effectively remains 45% above that ceiling.

CSG/CRDS social contributions also apply on employment and capital income at the same rates as metropolitan France (9.7% combined on earnings; 17.2% on capital income).

How does corporate tax work?

The metropolitan French impot sur les societes (IS) rate of 25% applies in Martinique. SMEs with turnover under EUR 10 million pay a reduced 15% on the first EUR 42,500 of taxable profit.

Martinique companies eligible for the Defiscalisation Outre-Mer framework can also access the credit d'impot for productive investment (LODEOM Art. 244 quater W CGI). France implemented EU Pillar Two (GloBE) rules for fiscal years from 31 December 2023; Martinique is covered as a French DOM, though very few MNEs are domiciled there.

What is Defiscalisation Outre-Mer?

Defiscalisation Outre-Mer is one of Martinique's most significant tax features. It is a set of investment-incentive instruments created to stimulate economic development in French DOMs.

What are the TVA rates and Octroi de Mer?

Martinique operates under DOM-specific TVA rates significantly lower than metropolitan France. These apply instead of — not in addition to — the metropolitan rates.

In addition to TVA, Martinique applies Octroi de Mer — a sea-tax on imported goods arriving in the DOM. Rates range from 0% to 15% depending on the product category. Octroi de Mer is collected by local authorities and exists alongside TVA; imports can therefore carry both charges. It functions as a trade-protection measure for locally produced goods.

The metropolitan French TVA standard rate of 20% does not apply in Martinique. This is one of the largest practical differences a business operating in both metropolitan France and Martinique will encounter.

What is the currency framework?

How are cryptoassets taxed?

French crypto taxation rules apply in full to Martinique residents. Under Article 150 VH bis CGI, occasional disposals of cryptoassets are subject to the prelevement forfaitaire unique (PFU) at 30% — comprising 12.8% income tax and 17.2% social levies. Filers may elect the progressive income-tax brackets instead, useful for those in the 0% or 11% band.

Habitual or professional trading is categorised as benefices non commerciaux (BNC) and taxed at progressive rates plus full social levies. Mining and staking are taxable as ordinary income at receipt. Non-French crypto accounts must be declared on Form 3916-bis; failure to declare triggers EUR 750–1,500 per-account penalties.

France's ACPR and AMF jointly regulate cryptoasset service providers (CASPs) — the same regime applies to providers operating in Martinique.

What is the treaty network?

Martinique residents are French tax residents and qualify under all of France's bilateral double-taxation conventions — approximately 125 active treaties, the largest network in Europe. France's treaties follow the OECD Model with French reservations; the OECD MLI is ratified and applies to many French treaties from 2019 onward.

Where a Martinique resident claims treaty relief, the claim routes through French DGFiP procedures — not through a separate DOM authority. MLI applies where France has activated it for a given treaty.

Where does Martinique sit in the French Caribbean cohort?

Martinique is part of the French Caribbean DOMs and COMs group. The cohort matters because each territory has a distinct fiscal relationship with metropolitan France:

The key distinction: DOMs (Martinique, Guadeloupe, Guyane, La Reunion) are French departements — metropolitan French law applies directly, with specific DOM modifications. COMs (Saint Martin, Saint Barthelemy) have their own fiscal autonomy — they set their own rules and generally have no VAT and lower or no income tax.

Common pitfalls and traps

Operators and investors commonly trip on these Martinique-specific issues:

Economy snapshot

Martinique's economy rests on tourism, financial services, and agricultural exports — primarily AOC Rhum Agricole and bananas. Sugar production declined sharply after EU quota reforms. The Girardin framework was designed partly to attract metropolitan French capital to offset the structural import-dependence of an island economy.

Decision flow — when to call a Martinique tax pro

When should you talk to a Martinique tax pro?

Some situations are clear enough to handle via impots.gouv.fr. Others benefit from a credentialed expert-comptable or avocat fiscaliste with DOM experience:

• You split time between Martinique and metropolitan France and need to identify where your foyer fiscal sits
• You are investing in a Girardin Industriel or Girardin Logement scheme and need to verify commissioning deadlines and documentation
• You run a business and want to confirm LODEOM employer-exoneration eligibility for your sector
• You import goods regularly and need clarity on how Octroi de Mer rates interact with your 8.5% TVA obligations
• You have investment income and want to evaluate the PFU versus progressive-bracket election
• You hold non-French bank or crypto accounts and are unsure whether the 3916 / 3916-bis declaration applies
• You received a DGFiP notice of assessment, audit letter, or compliance query
• You are moving to or from Martinique mid-year and need to determine residency start/end date
