Capital Gains on a Primary Residence: Rules, Exemptions, and Special Cases

When reselling a property, the prospect of making a financial gain (known as a capital gain) is common. In France, real estate is subject to strict taxation on capital gains. Fortunately, the sale of a primary residence benefits from a particularly advantageous exceptional regime.

While total exemption is the general rule, the tax authorities apply strict criteria to grant this privilege. What pitfalls should you avoid? What happens in the event of a prior move or divorce? MeCaza provides a comprehensive overview to secure your transaction.

‍

1. The Golden Rule: Total Exemption in Principle

In accordance with Article 150 U of the General Tax Code (CGI), capital gains realized from the sale of real estate used as primary residence on the day of sale are fully exempt from income tax and social security contributions.

‍

What is meant by "Primary Residence"?

For tax purposes, this refers to the dwelling where your main interests lie, meaning the place where you effectively and habitually reside for the majority of the year.

There is no minimum legal occupancy period set by law. However, in the event of a very quick resale (less than one year after purchase), the tax authorities may conduct an investigation to ensure it is not a disguised property dealer operation. To prove your good faith, your income tax returns, energy bills (electricity, gas), and local housing tax notices (if applicable) must all point to this address.

If the property sold is not your primary residence, tax applies automatically. Discover how this real estate value is included in the overall calculation of your assets in our guide on property tax and real estate wealth tax.

The real estate capital gains tax schedule (excluding primary residence)

If the property sold does not meet the criteria for a primary residence (secondary residence, rental investment, or vacant property outside legal deadlines), the gain realized is subject to tax.

The gross capital gain is then taxed at a flat global rate of 36.2%, to which a progressive surtax is added if the net gain exceeds the €50,000 threshold. Here is a summary of the applicable rates and the timeframes required to become fully exempt from this tax through allowances for length of ownership:

Although these actual rates are high, the allowance mechanism allows for a reduction in the taxable base each year starting from the 6th year of ownership. This is why, during an asset management decision, the precise calculation of the date of signing the authentic deed can save you several thousand euros.

‍

2. The critical case: The property is vacant at the time of sale

This is the most common situation: you buy a new home, you move out, and your former primary residence remains empty while you find a buyer. Are you still exempt?

Yes, but under strict conditions. The tax authorities grant an allowance if the following conditions are met:

• The property was indeed your primary residence at the time it was put up for sale.
• The property remained free of any occupation (formal prohibition against renting it out, even on Airbnb, or housing a relative there for free in the interim).
• The sale occurs within a "normal timeframe" for sale.

‍

⚠️ What is a normal timeframe for the tax authorities?

‍Generally, the tax authorities consider that a period ofone year is normal for selling a property. This period can be extended if the economic climate is difficult or if you prove that you have lowered the price to adapt to the market (via successive sales mandates).

‍

3. What about outbuildings (garages, cellars, gardens)?

The capital gains tax exemption extends to immediate and necessary ancillary structures of the dwelling, provided that they are sold at the same time as the main dwelling.

• The garage or cellar: If they are located in the same building or at an adjacent address and are transferred to the same buyer in the same deed, they benefit from total exemption.
• Building plots: Beware of this pitfall! If you separate a part of your garden to sell it as an independent building plot, the capital gain realized on this land will be fully taxable (19% income tax + 17.2% social security contributions), because it does not constitute the dwelling itself.

‍

4. Separation, divorce, and professional relocations: Legal exceptions

Life has its unforeseen circumstances that sometimes force people to leave the family home long before the signing of the deed of sale. The tax authorities show flexibility in three major situations:

‍

Divorce or Separation (Marriage, Civil Partnership, Cohabitation)

In the event of a breakup, one spouse often leaves the home while the other remains until the sale. The ex-spouse who moved out retains their right to capital gains tax exemption, even if they no longer live in the property on the day of the sale, provided that:

1. The property was their primary residence at the time of separation.
2. The sale is a direct result of this separation (division of assets).
3. The other ex-spouse continued to occupy the property until the final signing.

‍

Moving into a Retirement Home or Specialized Facility

Elderly or disabled adults who leave their primary residence to move into a long-term care facility continue to benefit from the exemption. The sale must occur within 2 years following their departure, and the property must have remained vacant since that date.

💡 MeCaza's Expert Insight

‍Many homeowners impulsively lose their right to the exemption. With increasingly longer selling times, there's a strong temptation to rent out their former primary residence "just for a few months" to cover the mortgage payments during the transition.

This is a major tax mistake: from the very first day of rental, the property's status changes in the eyes of the tax authorities and it becomes a rental investment. Upon resale, your capital gain will be taxed at 36.2%, mitigated only by allowances for the duration of ownership. It's better to make a quick price adjustment than to face a devastating tax reassessment.

FAQ: Essential questions about capital gains

Can employer-provided housing be considered a primary residence?

No. If you live rent-free or out of necessity in employer-provided housing, your personal home (which you own) is considered, for tax purposes, a secondary residence. When it is resold, the capital gain is taxable, unless you apply for the exceptional exemption for the first sale of a secondary residence (provided you reinvest the money in the purchase of your future primary residence within 24 months).

‍

How is the tax calculated if the exemption is denied?

If the tax authorities reclassify your sale, the gross capital gain is equal to the difference between the selling price and the initial purchase price. This amount is reduced by allowances per year of ownership (income tax exemption after 22 years, and social security contributions exemption after 30 years). The overall tax rate is 36,2% (19% income tax + 17.2% social security contributions), to which a surcharge of 2% to 6% may be added if the net capital gain exceeds €50,000.

‍

Does mixed use (professional and residential) eliminate the exemption?

Only the portion of the property allocated to the primary residence is exempt. If you use 20% of your home's area for your professional activity (commercial office, medical practice) and these rooms are listed as assets of your company, the professional capital gain will be calculated and taxed on that 20%.
