Historic Monuments simulator: deducting expenses from total income
The historic monuments scheme lets you deduct all the expenses and works on a listed or registered property from your total income, with no ceiling and outside the overall cap on tax breaks. At a marginal tax rate of 41% or 45%, the effect on your tax bill is considerable.

Why
Why the historic monuments scheme is the pinnacle of property tax breaks
Where most schemes grant a capped tax reduction, the Historic Monuments regime works on a radically more powerful principle: deduction. All of the property's expenses — restoration works, loan interest, upkeep costs — are deducted from total income, with no ceiling and outside the overall cap on tax breaks. For a taxpayer at the top of the progressive scale, the tax saving follows the marginal rate directly.
In practice, in the 45% bracket, every euro of deductible expense means 45 cents less tax. On a major restoration programme, the deducted expenses can wipe out a large share of income tax, with no ceiling. That is precisely what reserves this scheme for heavily taxed investors: its benefit rises mechanically with the marginal tax rate.
But the advantage cannot be separated from its object: a property listed or registered as a Historic Monument. Acquiring and restoring such a property is a long-term wealth project, in which tax combines with estate transfer, a passion for wealth and a retention commitment. It is not a standardised tax product; it is a wealth lifestyle choice.
What the calculation shows
The 3 levers of the historic monuments scheme
No limit on the amount, and nothing counted against the €10,000 cap on tax breaks. The tax saving is directly proportional to your marginal tax rate — hence a benefit that peaks at 41% or 45%. For heavily taxed wealth carrying a large works programme, this is where the scheme comes into its own.
The regime's benefit requires a commitment to keep the property for 15 years. On top of this come strict obligations linked to its protected status: works approved by the authorities, sometimes opening to the public, compliant upkeep. It is not an investment you can unwind at will: it is a long-term wealth commitment that you must be prepared to honour.
Listed or registered properties are rare, unusual and expensive, and every file is a special case — condition of the property, nature of the works, administrative constraints, narrow resale market. The specific nature of the regime calls for expert support, on the tax side as well as on choosing the property and managing the works. A misjudgement is paid for over a long time on an illiquid asset.
Case study
Case study: Catherine, 56, head of a family group in Lyon
Catherine, taxed at 45%, buys a town mansion registered as a Historic Monument and commits €100,000 of restoration works over the year. Here is what the simulator calculates on the basis of her marginal rate:
| Indicator | Amount | Comment |
|---|---|---|
| Deductible expenses and works | ≈ €100,000 | deducted from overall income |
| Marginal tax rate | 45% | top of the progressive scale |
| Tax saving | ≈ €45,000 | no ceiling, outside the tax break cap |
| Retention commitment | 15 years | obligations attached to the protected property |
In the 45% tax bracket, the €100,000 of deductible expenses generates ≈ €45,000 in tax savings, with no ceiling and outside the cap on tax breaks. And the effect recurs as the works progress.
In return, Catherine undertakes to keep the property for 15 years and to comply with the obligations attached to its registered status. For her, the transaction makes sense because it fits a logic of family transmission and a passion for wealth, not just tax reduction. That is the condition for success with this regime.
In practice
Historic Monuments: a wealth strategy, not a product
This simulator quantifies the tax saving from deducting expenses. But this regime is more than a calculation: it commits you for 15 years, on a rare and demanding asset, with estate transfer as much as optimisation in mind. Choosing the property, estimating the works, meeting the obligations and fitting it into your estate strategy all call for high-level support.

Frequently asked questions
What clients ask us.
Why is the Historic Monuments regime more powerful than a tax reduction?
Because it works by deduction, not by reduction. All expenses (works, loan interest, costs) are deducted from total income, with no ceiling and outside the overall cap on tax breaks. The saving is directly proportional to your marginal tax rate: at 45%, each euro deducted is worth 45 cents less in tax.
Is there a ceiling on Historic Monuments deductions?
No — that is the distinctive feature of the regime: expenses are deducted from total income with no ceiling on the amount and outside the overall €10,000-a-year cap on tax breaks. That is also what reserves it for heavily taxed households with a high total income to offset.
What are the regime's constraints?
The benefit requires a commitment to keep the property for 15 years, as well as compliance with strict obligations linked to its listed or registered status: works approved by the authorities, compliant upkeep, sometimes opening to the public. It is a long-term wealth commitment, not a tax operation you can unwind as you please.
Who is this scheme for?
For heavily taxed taxpayers (41% or 45% bracket) with high total income to offset, who are prepared to commit to an exceptional property with a long-term, estate transfer perspective. It is as much an investment driven by a passion for wealth as a tax optimisation: you have to believe in the project, not just in the tax saving.
Why is advice from outside the developer essential here?
Because each listed or registered property is a special case, in a rare and illiquid market, with heavy administrative constraints and a 15-year commitment. Balmont Conseil, an open-architecture firm and member of ANACOFI-CIF, has no ties to any developer or property dealer: we select the property on its wealth quality alone and secure the tax and succession structuring, in your interest.
