What is a real estate capital gain and when should you declare it
A real estate capital gain is the difference between the sale price and the purchase price of a property The purchase price can be increased by registration duties acquisition costs and under certain conditions deductible works The gross capital gain becomes a taxable capital gain after deduction of costs and application of holding period allowances
The triggering date is the date of the notarial deed The taxation falls under the tax year corresponding to that date The real estate capital gains declaration is then included in the income tax return via the dedicated boxes
Most formalities are handled by the notary who calculates the taxable capital gain and where applicable withholds tax at source Exceptions exist non residents certain exemptions or complex situations may require a direct declaration to the tax authorities
The properties concerned are varied main residence second home land commercial premises professional building or other assets within private wealth Some small sales may qualify as an exempt small disposal if they meet the relevant thresholds
If you are unsure about the classification of the property the existence of a capital gains exemption or the nature of deductible costs contact your notary or your local real estate advisor
Definition and components of the capital gain
The calculation base is the sale price actually received minus selling commissions and agency fees paid by the seller The purchase price includes the price paid at purchase increased by registration duties and acquisition costs
Deductible works are generally improvement works Routine maintenance works are excluded Invoices and supporting documents are essential for these deductions to be accepted
For furnished rentals the treatment is specific Depreciation recorded in accounts may have to be added back into the taxable base under the applicable rules From 2025 the depreciation add back may apply to sales completed from 15 February 2025 under certain conditions
Important distinction the gross capital gain is the difference between the net sale price and the increased purchase price The net taxable capital gain then results from applying holding period allowances and any applicable exemptions
Documents to gather purchase deed proof of registration duties invoices for deductible works proof of agency fees and any other relevant supporting documents
Properties concerned main residence second home land commercial premises
The sale of a main residence is generally exempt from capital gains tax if the property was actually occupied as such at the time of sale Normal outbuildings such as a garage or garden follow the same regime when they are inseparable from the home
A second home generally generates a taxable capital gain Sales of building land or commercial premises also often trigger specific taxation Professional buildings may fall under a different regime and require additional supporting documents
For a mixed use property part occupied part rented classification can be complex In that case the notary and a tax advisor are the recommended contacts to define the taxable base and check whether exemptions linked to the seller or buyer apply
How to calculate the real estate capital gain step by step
The real estate capital gain calculation follows a simple chronological process Start by gathering the purchase deed registration duties work invoices and proof of agency fees Then calculate the net sale price and the increased purchase price
Next apply holding period allowances to obtain the taxable base for capital gains tax Then calculate social contributions on the corresponding base Online real estate capital gain simulators can help estimate the amounts
You can choose a flat rate option where the law allows or use actual costs Supporting documents strengthen your file and reduce risk in case of a tax audit
The boxes to complete on the income tax return are 3VZ and 3VW The notary generally provides the summary needed to fill in these boxes
Sale price purchase price and costs to include
The sale price to use is the amount actually received minus commissions and agency fees paid by the seller Keep proof of these payments
The purchase price includes the initial price increased by registration duties and acquisition costs Deductible improvement works extension creation of additional space replacement of major equipment can be added to the purchase price if you provide invoices
Without invoices the tax authorities may refuse the deduction Always request dated and signed documents for works and professional services
Holding period allowances and how they apply
The holding period allowance progressively reduces the taxable base For income tax it is 0 percent for the first 5 years then 6 percent per year from the 6th to the 21st year and 4 percent in the 22nd year resulting in income tax exemption after 22 years
For social contributions full exemption generally occurs after 30 years of ownership These allowances are applied differently depending on whether they concern the income tax base or the social contributions base
Exceptional allowances exist but are rare Always check the exact schedule and rates on service public fr or impots gouv fr
Practical worked example capital gain calculation
Example purchase in 2005 for 200000 euros registration duties 10000 euros works 20000 euros Sale in 2026 for 350000 euros agency fees 15000 euros
Step by step net sale price 350000 minus 15000 equals 335000 euros Increased purchase price 200000 plus 10000 plus 20000 equals 230000 euros Gross capital gain 335000 minus 230000 equals 105000 euros
If the holding period is 21 years holding period allowances will be applied to reduce the income tax base Social contributions follow their own schedule The notary will indicate the estimated amount and withholding at source where applicable
This example highlights the importance of supporting documents For an accurate estimate request a real estate capital gain simulation from your local real estate advisor or the notary
Tax and social contributions what is declared and how
The tax treatment has two components capital gains tax linked to income tax and social contributions Social contribution rates can change Check the current figures on impots gouv fr
The notary often withholds the calculated tax at source and pays it to the public treasury This notary withholding is an advance payment In some cases the seller must declare and pay directly especially if they are non resident or if a specific exemption applies
A capital gain can temporarily increase your reference taxable income This increase can affect eligibility for certain benefits Check the pre filled return and the amounts in boxes 3VZ and 3VW
Income tax versus social contributions
Capital gains tax is calculated after applying holding period allowances Social contributions are then added based on another scale and another base
The amount entered in box 3VZ can increase reference taxable income without double taxation If in doubt ask the notary for the detailed calculation and keep all supporting documents
Annual allowances and exemptions after 22 years and 30 years
Quick reminder 0 percent during years 0 to 5 then 6 percent per year from year 6 to year 21 then 4 percent in year 22 This leads to income tax exemption after 22 years For social contributions exemption occurs after 30 years
These rules are available on official websites and should be checked before choosing a sale date Consult the notary or an accountant to confirm what applies to your file
Administrative declaration and the role of the notary
The notary calculates the taxable capital gain checks supporting documents applies notary withholding when necessary and pays the tax to the authorities The notary provides the seller with a summary statement useful for the income tax return
If an exemption applies the notary states it in the deed and does not withhold tax However the seller should still verify the notarial deed and keep all documents provided The retention period depends on the limitation period
If there is an error first ask the notary for an explanation If the disagreement persists contact the tax authorities to file a claim or appeal
When the notary withholds and pays the tax
The notary generally withholds an advance corresponding to the tax and social contributions on the taxable capital gain This withholding at source is then paid to the public treasury
Special cases include non residents or exempt sales In these situations the notary may not withhold any amount The seller may then have to complete a non resident capital gain declaration or a direct declaration
The withholding is provisional A correction may occur the following year depending on the seller’s final tax situation
What to check on the deed and in the documents provided
Practical checklist verify the recorded sale price inclusion of agency fees inclusion of registration duties and recognition of deductible works Request a copy of the notary’s calculation
Keep supporting documents for the relevant period linked to the limitation period In case of an error start by notifying the notary then the tax authorities if necessary
Boxes to complete on the income tax return 3VZ and 3VW and impact on reference taxable income
Box 3VZ is for the taxable capital gain Box 3VW is for exempt capital gains that still need to be reported for example in the case of partial reinvestment These boxes are often pre filled based on information from the notary
The amount entered can increase reference taxable income This increase can affect eligibility for certain benefits Check the pre filled figures and correct them if necessary with the help of your notary
Exemptions and special cases
Several capital gains exemptions exist main residence first sale with reinvestment small disposal professional mobility or exemptions for elderly people subject to conditions Some exemptions are linked to the buyer’s status
Each scheme comes with conditions and required supporting documents The first sale with reinvestment requires using the sale proceeds to buy a main residence within a set timeframe The small disposal exemption depends on a specific threshold Contact the tax authorities or the notary to confirm thresholds and conditions
Sale of the main residence
