When you sell a property with an iad advisor, the commission deducted from the transaction can amount to several thousand euros. This amount, referred to as “fees” or “iad agency fees,” directly influences the net price you receive, but also, in some cases, the tax you pay on the capital gain. Understanding how this calculation works allows you to anticipate the real cost of the sale.
iad Agency Fees and Capital Gains Tax: A Often Overlooked Tax Link
Most sellers focus on the percentage displayed by the iad advisor. Few know that these fees can reduce the taxable capital gain declared to the tax authorities. The mechanism is simple: the tax administration allows the deduction of certain expenses related to the sale to calculate the taxable net capital gain.

Specifically, if you sell an apartment for more than you bought it, the difference constitutes a gross capital gain. The agency fees paid by the seller are part of the deductible expenses from this capital gain. The higher your fees, the lower the taxable base.
You can learn everything about iad agency fees to better understand their composition before incorporating them into your tax calculation.

Note: this deduction only works if the fees are contractually the responsibility of the seller. When the mandate states that the buyer pays the commission, the seller cannot deduct it from their capital gain. The choice of payer in the mandate thus has a direct tax consequence.
Calculation of iad Fees: Percentage and Degressive Scale
iad, like most networks of agents, applies a freely set commission scale. In France, no regulation imposes a ceiling on transaction fees. The commissions charged by agencies and networks generally range from 3% to 10% of the sale price.
At iad, the percentage tends to decrease as the price of the property increases. For an apartment sold at a modest price, the commission represents a proportionally higher share. For a property of a higher value, the rate applied decreases.
What the Scale Includes
iad fees cover the entire service provided by the real estate advisor:
- The property valuation, writing the listing, broadcasting on portals, and organizing visits
- Qualifying potential buyers, negotiating between the parties, and administrative follow-up until the signing at the notary
- Basic legal support (verification of mandatory diagnostics, compliance of the mandate with the Hoguet law)
Fees are only due in the event of an actual sale, at the time of signing the authentic deed. No deposit can be requested before this stage.
Net Seller Price and Displayed Price: Understanding the Difference
When you consult a real estate listing, the displayed price may or may not include the fees. Two mentions exist: “fees payable by the seller” or “fees payable by the buyer.” This distinction changes the interpretation of the price.
If the fees are payable by the seller, the displayed price corresponds to the total amount paid by the buyer. The seller receives this amount minus the commission. If the fees are payable by the buyer, the displayed price corresponds to the net seller price, and the buyer adds the commission on top.
An Example for Clarity
Let’s take a property for sale with fees representing about 5% of the price. If the displayed price is 200,000 euros (fees payable by the seller), the seller will receive about 190,000 euros net. The notary deducts the commission on the day of signing and forwards it to the iad network.
The net seller price is the only figure that matters for your actual budget. Always ask your advisor to provide a simulation distinguishing the sale price, the amount of fees, and the net received.
Negotiating iad Agency Fees: Real Margin and Limits
The fees of an iad advisor are negotiable. No legal text prohibits discussing the applied percentage. In practice, the margin for negotiation depends on several factors.
A property that is easy to sell (sought-after location, good condition, price consistent with the market) leaves less room for negotiation for the seller: the advisor knows they will sell quickly. Conversely, an atypical property or one located in a less sought-after area may justify a discussion about the commission rate.
The negotiation concerns the percentage, not the included services. Reducing the fees does not mean that the advisor will make fewer visits or write a less detailed listing. The mandate describes the professional’s obligations, regardless of the agreed rate.
Elements to Check Before Signing the Mandate
- The type of mandate (simple or exclusive), as an exclusive mandate may come with a more advantageous rate
- The explicit mention of the amount of fees in euros and as a percentage, indicating who is responsible for them
- The duration of the mandate and the termination conditions, to avoid being committed if the sale does not progress
In Île-de-France, average fees remain higher than in the provinces. According to the Meilleurs Agents Barometer of September 2025, iad fees in regions like Occitanie tend toward lower rates, favored by increased competition among local agents.
Transparency regarding iad agency fees remains the best lever for a seller. Reading the mandate in detail, checking the distribution of fees, and measuring their impact on the taxation of the capital gain allows for approaching the sale with a comprehensive view of the real cost of the transaction.
