Micro-BIC vs. Actual Expenses: Which Tax Regime for a Furnished Rental in Martinique

You’ve just collected your first rental income for a studio in Sainte-Anne, a one-bedroom in Trois-Îlets, or a villa facing the Diamond Rock: should you stay on the micro-BIC scheme or switch to the actual-expenses regime? It’s the most profitable decision of your year as a landlord, and yet the one most often made carelessly. When it comes to micro-BIC and actual expenses in Martinique, the tax gap between the two regimes isn’t measured in tens of euros, but in thousands, every year.

As an island resident and manager of furnished tourist rentals, I see both scenarios play out for every property we look after. Because Martinique is a French overseas department and region (DROM), the taxation of furnished rentals follows national rules — but local realities often tip the scales. Here is a numbers-based comparison, up to date for 2026, that remains educational: only a chartered accountant can validate your specific case.

Micro-BIC and actual expenses: two opposite logics for the same rent

A short-term furnished rental falls under Industrial and Commercial Profits (BIC), not property income. If it isn’t your full-time job, you fall under the LMNP status (Non-Professional Furnished Landlord), and two regimes are available to you.

Micro-BIC: a flat rate, zero paperwork

Micro-BIC applies a flat-rate allowance to your gross income: the tax authorities assume a fixed percentage covers your costs, with no supporting documents. Since the reform known as the “Le Meur law,” effective on 2025 income declared in spring 2026, the micro-BIC allowance for a furnished tourist rental depends on classification:

Classified furnished rental: 50% allowance, income cap of €77,700 per year.
Unclassified furnished rental (most of the island’s seasonal Airbnbs): 30% allowance, with the cap lowered to €15,000.

You declare a single figure, your collected rents, and the administration applies the allowance. No financial statements, no bookkeeping.

The actual-expenses regime: the precision that erases the tax

Under the actual-expenses regime in LMNP in the overseas departments (DOM), you forget the flat rate: you deduct your actual costs and, above all, you depreciate the property and the furniture. Depreciation is an accounting expense that doesn’t leave your cash flow but wipes out most of the taxable profit. Deductible items include loan interest, property tax, insurance, concierge services, and most importantly the depreciation of the building (excluding land, 2 to 3% per year) and of the furniture (5 to 10 years).

The trade-off: mandatory bookkeeping, often entrusted to a chartered accountant (€250 to €600 per year in Martinique, deductible) and an annual 2031 tax return.

The decisive factor: your costs versus the allowance

The rule fits in one sentence. If your actual costs exceed the flat-rate allowance, actual expenses win. And several Martinican realities inflate actual costs and often tip the decision toward actual expenses:

Tropical climate: the air conditioning runs almost year-round, and restoring the property after the cyclone season (June to November) comes around regularly.
Octroi de mer: imported furniture costs more than in mainland France, which increases the depreciable base.
Ongoing loan: loan interest is heavy in the early years and can only be deducted under the actual-expenses regime.

Conversely, micro-BIC still makes full sense if you rent without a loan, with few costs.

A numbers-based comparison: three realistic Martinican rentals

Let’s take three credible cases from the island’s market (rounded figures, social levies of 17.2% included, marginal tax bracket assumed at 30%).

Case 1 — Classified studio in Sainte-Luce, no loan

Income: €9,000/year (seasonal, Caribbean coast). Property bought outright, modest actual costs ≈ €3,000/year. Classified furnished rental, 50% allowance.

Micro-BIC: taxable base = €4,500. Actual expenses: 9,000 − 3,000 = €6,000 before full depreciation; even when optimized, you stay close to micro-BIC, which wins on simplicity. Verdict: micro-BIC.

Case 2 — Mortgaged one-bedroom in Sainte-Anne, 15 min from Les Salines

Income: €16,000/year (seven full weeks during the Lent high season at €110–130 a night). Actual costs: loan interest €5,200, property tax and CFE €1,100, insurance and concierge €1,800, building + furniture depreciation ≈ €6,500. Total ≈ €14,600/year. Classified furnished rental, 50% allowance.

Micro-BIC: taxable base = €8,000 → tax + social levies ≈ €3,776. Actual expenses: 16,000 − 14,600 = €1,400 of profit → ≈ €661. Saving under actual expenses: more than €3,100 per year. Verdict: actual-expenses regime.

Case 3 — Unclassified villa in Le François, near the white sandbanks

Income: €24,000/year (strong demand for large rentals in the South Atlantic area). Unclassified furnished rental: micro-BIC cap of €15,000 exceeded.

Above €15,000 for an unclassified furnished rental, micro-BIC is no longer available: the actual-expenses regime becomes mandatory. With cleaning, concierge services, and depreciation, the taxable profit often drops near zero in the early years. Verdict: actual-expenses regime (imposed by the caps).

The decision grid to remember

Situation	Recommended regime
No loan, few costs, low income	Micro-BIC
Recent mortgaged purchase (high interest)	Actual expenses
Imported furniture or major renovations	Actual expenses
Income on an unclassified rental > €15,000	Actual expenses (mandatory)
You want zero bookkeeping	Micro-BIC

A local tip often changes the picture before you even decide: getting your tourist rental classified raises the micro-BIC allowance from 30 to 50% and lifts the cap to €77,700, for €150 to €250 of inspection valid for five years. Enough to make micro-BIC attractive again for a well-booked seasonal rental. We detail the process in our Martinique guide.

Specific points to watch in the Martinican overseas department

Opting for actual expenses is a commitment: it lasts at least one year and renews automatically. Consider it from the very launch of your activity.
The time difference complicates exchanges with a mainland accountant: −5 h in winter, −6 h in summer compared to Paris (area code +596).
Keep every invoice, especially for imported furniture subject to the octroi de mer: they feed your depreciation under the actual-expenses regime.

Finally, the micro-BIC or actual-expenses choice exempts you neither from the CFE nor from the tourist tax that you collect for the municipality: separate matters, to be handled in parallel.

Managing a profitable furnished rental in Martinique, beyond the tax regime

The right regime isn’t everything: a high-performing rental relies on a solid occupancy rate and smooth management. In Martinique, where a car is strongly recommended and where travelers (couples chasing sunsets on the Caribbean coast, families taking in Les Salines, Mount Pelée, and the Rum Trail) have precise expectations, the welcome makes the difference.

That’s where Hostel Toucan comes in, a concierge service established in the overseas departments. We manage your rental from A to Z and produce a clear summary of your income and costs that simplifies your actual-expenses declaration as much as your micro-BIC tracking. For travelers, booking directly means no platform fees, free cancellation up to 7 days before arrival, and WhatsApp support 7 days a week.

The right regime, combined with expert management, means several thousand euros of difference over the year.

FAQ

Micro-BIC or actual expenses: which pays the least tax for a furnished rental in Martinique?

It all depends on your costs. If your actual costs (loan interest, property tax, CFE, insurance, concierge services, and above all depreciation) exceed the micro-BIC flat-rate allowance, actual expenses pay significantly less. For a one-bedroom bought on credit in Sainte-Anne or Trois-Îlets, the saving commonly reaches €2,500 to €3,500 per year. Without a loan and with few costs, micro-BIC remains simpler and just as advantageous.

What is the income cap to stay on micro-BIC?

For a classified furnished tourist rental, the cap is €77,700 of annual income with a 50% allowance. For an unclassified furnished rental — the majority of seasonal Airbnbs — it drops to €15,000 with a 30% allowance. Above that, micro-BIC is no longer available and actual expenses become mandatory.

Can you depreciate a furnished rental in Martinique as in mainland France?

Yes. Because Martinique is a French overseas department (DROM), the rules apply identically. Under actual expenses, you depreciate the building (excluding land) and the furniture over 5 to 10 years. It’s this depreciation that often cancels out the taxable profit in the early years — an advantage reinforced in the overseas departments, where imported furniture, made more expensive by the octroi de mer, inflates the depreciable base.

Does classification as a tourist rental change the choice of regime?

Yes, indirectly but clearly. Classification raises the micro-BIC allowance from 30 to 50% and lifts the cap from €15,000 to €77,700. For an unclassified seasonal rental that exceeds €15,000 of income, it can avoid switching to actual expenses. The inspection costs €150 to €250 for five years, quickly paying for itself.
