Property tax vs residence tax: key differences before you buy or rent

Property tax vs residence tax: why they matter in a buy or rent decision

In France, local property taxes can add up to hundreds or even thousands of euros per year. When you compare buy or rent, ignoring these amounts makes the “mortgage vs rent” comparison misleading.

Since the reform of the residence tax (taxe d’habitation) on main homes, many people think local taxes have disappeared. They haven’t: property tax (taxe foncière) is still due every year by owners, and in many cities it is rising faster than inflation.

In a simulator like buy-or-rent.net / acheter-ou-louer.com, this cost is captured by the parameter taxe_fonciere_annuelle. It is one of the items that can tip the balance in the long-term calculation between buy or rent, especially in big cities.

1. Property tax (taxe foncière): the unavoidable owner’s tax

1.1. Who pays property tax?

Property tax (taxe foncière) is paid by the owner (or usufructuary) of a property as of January 1st of the year. Whether you live in the home or rent it out, you pay it. A tenant does not directly pay the property tax on their dwelling (except in some cases for waste collection charges passed through).

So in a buy or rent comparison:

• If you rent: you do not pay property tax on that home.
• If you buy: you must budget for an annual property tax, often between €450 and more than €5,000 depending on the city and the type of property.

1.2. How is property tax calculated?

In simplified terms, property tax = Cadastral base × Local tax rates. The cadastral base is a theoretical annual rental value assigned to the property. It is revalued each year by the State (often around inflation, sometimes more), and then municipalities and other local bodies apply their own tax rates.

This has two key consequences for your buy or rent analysis:

• Property tax is not fixed: it generally rises every year. In a simulator, this is modeled with an annual revaluation rate (for example +3% per year).
• It varies widely between cities: for the same type of property, you might pay €600/year in one municipality and €1,800/year in another.

1.3. Numerical example: 20-year impact

Suppose you buy an apartment and the starting taxe_fonciere_annuelle is €1,200 in year one, with an average increase of 3% per year.

• Year 1: €1,200
• Year 10 (approx.): €1,200 × 1.03⁹ ≈ €1,565
• Year 20: €1,200 × 1.03¹⁹ ≈ €2,170

Over 20 years, the total paid will be roughly €1,200 × (1.03²⁰ − 1) / 0.03 ≈ €32,200. This amount is on top of your mortgage interest, notary fees, maintenance, etc.

In a buy or rent comparison, ignoring property tax means underestimating the real cost of ownership by around €1,600/year on average over 20 years in this example.

2. Residence tax (taxe d’habitation): what changed and what remains

2.1. The end of residence tax on main homes

Residence tax (taxe d’habitation) used to be paid by the occupant (owner-occupier or tenant) as of January 1st. It has now been abolished for almost all main residences:

• For the vast majority of households: no more residence tax on their main home.
• For second homes and some vacant dwellings: residence tax still applies, sometimes with a surcharge in high-demand areas.

Consequences for a buy or rent decision:

• Tenant in a main home: you no longer pay residence tax on that home (with some rare exceptions).
• Owner-occupier of a main home: same, no residence tax, but you do pay property tax.
• Owner of a second home: you pay both property tax and residence tax (and possibly a surcharge).

2.2. Example: main residence vs second home

Imagine two situations:

• Case A: you rent your main home
  You do not pay property tax, and you no longer pay residence tax on that main home. Your local taxes linked to housing are basically limited to waste collection inside your service charges.
• Case B: you buy a second home
  For that second home, you pay:
  • Property tax: say €900/year.
  • Residence tax on the second home: say €600/year, possibly more in a high-pressure market.
  That’s €1,500/year of additional local taxes, excluding any future increases.

In a buy or rent simulator, the core main-residence comparison now revolves around property tax. But if you are considering a second home, residence tax becomes relevant again.

3. Why property tax weighs heavily in a buy or rent calculation

3.1. Mortgage vs rent: a misleading shortcut

You often hear: “My mortgage payment will be about the same as my rent, so buying must be better.” This comparison ignores several factors:

• Annual property tax (the taxe_fonciere_annuelle parameter in the simulator).
• Notary fees (7–8% in existing properties, 2–3% in new build).
• Mortgage insurance (typically 0.25–0.45% of the loan amount).
• Maintenance and repairs (roof, boiler, energy upgrades, etc.).
• Property tax increases each year (revaluation).

Let’s use a simple example to isolate the role of property tax.

3.2. Numerical example: same monthly payment, different total cost

You hesitate between buying or renting an apartment.

• Renting option: rent €1,000/month, i.e. €12,000/year, indexed to the IRL at +2%/year.
• Buying option: mortgage payment €1,000/month (€12,000/year), loan at 3.6% over 25 years, insurance 0.30%, property tax €1,200/year initially, property tax revaluation +3%/year.

On paper, €1,000 vs €1,000 looks equivalent. In reality:

• Tenant: you pay €12,000/year, plus some service charges, but no property tax.
• Owner: you pay €12,000/year in mortgage + €1,200 of property tax in year one, and that tax rises each year.

Over 10 years, with a +3%/year property tax increase:

• Total property tax ≈ €1,200 × (1.03¹⁰ − 1) / 0.03 ≈ €13,700.

This comes on top of your mortgage. As a renter, that cost simply doesn’t exist. The comparison is therefore not just “€1,000 vs €1,000”, but more like “€1,000 vs €1,000 + local taxes”.

In return, the owner is building home equity, which is the investment side of the buy or rent trade-off. To compare fairly, you must include taxe_fonciere_annuelle and its likely growth.

4. Property tax, inflation and purchasing power

4.1. Annual inflation and tax base revaluation

Annual inflation erodes purchasing power, but it also drives the revaluation of cadastral rental values. In recent years, these values have sometimes been revalued by 3–4% per year or more.

If inflation is 4% and your property tax also rises by 4%, your tax is increasing at the same pace as general prices. If your income grows more slowly, property tax will gradually take a bigger slice of your budget.

4.2. Example: 15-year drift

Assume:

• Initial property tax: €900/year.
• Average annual increase: +4%.

After 15 years:

• Annual amount ≈ €900 × 1.04¹⁴ ≈ €1,642.
• Total over 15 years ≈ €900 × (1.04¹⁵ − 1) / 0.04 ≈ €18,000.

If your salary has not increased at the same pace, your saving capacity is reduced. In the renting scenario, you don’t pay property tax, but your rent increases with the IRL. In a buy or rent simulator, we model:

• Annual rent increase (IRL) on the renting side.
• Property tax revaluation on the ownership side.

Whether buy or rent is more favorable will then depend on how these two dynamics compare over time.

5. Property tax: differences by city and property type

5.1. Wide range of amounts: from €450 to over €5,000

Property tax varies a lot:

• Small town or rural area: house with garden, property tax sometimes around €500–900/year.
• Big city or highly indebted municipality: apartment or house, property tax easily above €1,500–2,500/year, and over €5,000 for some high-end properties.

For the same purchase price, the impact on your annual budget can be radically different. In a buy or rent simulator, the taxe_fonciere_annuelle parameter must therefore be entered realistically, based on:

• The seller’s actual tax bill (ask for it during the purchase process).
• Local stats from the tax office or the city.

5.2. Example: two cities, same price, different property tax

You hesitate between buying in:

• City A: apartment at €250,000, property tax €800/year.
• City B: apartment at €250,000, property tax €1,900/year.

Difference: €1,100/year. Over 20 years, even ignoring tax increases, that’s €22,000. With a 2% annual revaluation, the cumulative difference exceeds €26,000.

In a buy or rent calculation, this gap can offset a higher rent in City A or make it more attractive to stay a renter and invest spare cash in financial assets (ETFs, savings accounts, etc.).

6. How to integrate property tax into a buy or rent strategy

6.1. As a buyer: plan, don’t just hope

When you simulate a purchase:

• Enter a realistic taxe_fonciere_annuelle (not a guess).
• Add a reasonable annual increase (for example 2–4% depending on local context).
• Include it in your full housing budget along with: mortgage payment at the current loan rate (~3.6% today), borrower insurance, condo fees, maintenance, notary fees, agency fees, etc.

Then compare that scenario with renting, where:

• You pay rent indexed to the IRL.
• You don’t pay property tax.
• You can invest the cash you don’t spend on buying at a given investment rate (savings accounts, ETFs, life insurance), modeled in the simulator.

6.2. As a renter: focus on long-term investing

Staying a renter means:

• No property tax on your home.
• No residence tax on your main home in most cases.
• But a rent that increases with the IRL over time.

The question is not only “pay property tax or not”, but also: what do you do with the money you don’t tie up in a purchase? If you simply spend it, the advantage of avoiding property tax can disappear. If you invest it at a solid investment rate over the long term, you may match or even beat the wealth you’d have built as an owner, despite paying rent and not benefiting from capital gains on a home.

7. Property tax vs residence tax: summary for a buy or rent choice

7.1. Key differences

• Property tax (taxe foncière):
  • Paid by the owner (occupier or landlord).
  • Applies to almost all built properties (with rare exemptions).
  • Ranges roughly from €450 to over €5,000 per year.
  • Tends to rise each year (revaluation of bases + local decisions).
• Residence tax (taxe d’habitation):
  • Historically paid by the occupant (owner or tenant).
  • Abolished for almost all main residences.
  • Still applies to second homes and some vacant dwellings, with possible surcharges.

For a main residence, property tax has become the main local tax that really changes the financial balance between buy or rent. Residence tax is now mostly an issue for second homes.

7.2. Important disclaimer

Whether you should buy or rent depends on many factors: your personal situation, time horizon, rent level, property prices, mortgage rates, local taxes, and life plans. The numerical examples above are simplified and do not constitute personalized financial advice.

To analyze your own case, you need a tool that accurately models taxe_fonciere_annuelle, rent increases, inflation, and potential investment returns on your savings.
