LMNP simulator: micro-BIC or actual regime?

Enter your rent, your charges and the price of your property: the simulator compares the tax due under both furnished-rental regimes.

The computation is instant and stays in your browser: nothing is stored.

The property
Price paid excluding notary fees; used to compute depreciation under the actual regime.
Share of the price that is not depreciable. The default suits most flats.
Notary and agency fees paid at purchase.
Added to the cost base, they are depreciated with the property; expensed, they are deducted in the year of purchase.
Furniture and equipment, depreciated faster than the building.
Capitalised works, depreciated over fifteen years.
It starts the depreciation. The simulator assumes the property enters the balance sheet on that date, with no earlier depreciation.
The rental
The simulator counts twelve monthly payments per projected year.
Charges for the year

Non-recoverable service charges, insurance, property tax, maintenance, management fees — excluding loan interest.

Amount paid during the year on the loan.
Interest declines in a straight line until the loan ends.

Total charges entered: 3 050,00 €

Projection assumptions
0 %, 11 %, 30 %, 41 % or 45 % depending on your income.
The actual regime is judged over several years: depreciation eventually runs out.
Applied from the second year, to rent and charges alike. A negative rate tests falling rent.

On these assumptions, the actual regime is taxed the least.

The actual regime is the cheaper option from the very first year.

Years marked with an asterisk rest on tax rules that are not final: the finance act covering them has not been published, and beyond 2026 the computation reuses that year's rules.

Under the actual regime, depreciation cannot create a loss: the part not deducted is carried forward to later years.

Points to check

  • Vos recettes (10 200,00 €) dépassent 5 000,00 € : la cotisation foncière des entreprises (CFE) est due (art. 1647 D CGI).
  • Les recettes des années 2025 et 2024 ne sont pas renseignées : l'éligibilité au micro-BIC a été estimée à partir des recettes de 2026 (art. 50-0 CGI).
  • L'immobilisation « Bien meublé — Mobilier » est totalement amortie à la clôture 2032 ; aucune dotation ne sera plus comptabilisée.

The actual regime requires bookkeeping and a set of tax statements; micro-BIC does not. The tax gap is therefore not the only criterion.

Indicative computation

This simulator produces an indicative computation, not tax advice. Check your situation against official sources or with a professional before filing.

Cerfa box numbers must be checked against the official form for the relevant tax year before you copy anything across.

Move on to the filing

The bail.immo LMNP module reuses your rent and expenses, computes your depreciation and tells you what to report, box by box.
