Short answer
The fiscal representative fee is treated as a selling cost and is deducted from the taxable gain on the 2048-IMM. That deduction lowers the income-tax capital gains tax of 19% and the social charges (7.5% or 17.2%) by the same base. The recovered amount is roughly a quarter to a third of the fee. It only happens if the invoice is in your name, dated before the deed, and effectively paid; otherwise the line is rejected on review.
How the deduction works on the 2048-IMM
French capital-gains tax for non-residents is computed in three stages on form 2048-IMM. First, you start from the gross gain (sale price minus acquisition price). Second, you deduct allowable selling costs and add allowable acquisition costs (notarial fees on purchase, works supported by invoices, and selling costs). Third, you apply the holding-period taper for income tax and a separate, slower taper for social charges. The fiscal representative fee enters at the second stage, on the selling-costs line. It is the same line that holds diagnostic costs, the agency commission billed to the seller, and certain mandatory survey fees.
Because the deduction happens before the taper, it survives even after long holding periods, until the taper reaches 100%. On a fifteen-year hold the income-tax base is reduced by roughly 30% by the taper; the fee deduction still lowers the residual base by the same nominal amount, so the recovery rate is unchanged in proportion.
The three conditions you must respect
The tax authority accepts the deduction when three boxes are ticked. The invoice is issued by the accredited firm to the seller (not to the notaire, not to a holding entity, not to the buyer). The invoice date precedes the date of the deed by at least one business day; same-day invoices are tolerated when the deed timestamp is later, but the safer pattern is to invoice the day before. And the fee is paid, by bank transfer, by debit on the proceeds at the notaire study, or by escrow release; an unpaid invoice does not qualify.
If the firm sub-contracts the file to another structure (this happens more often than non-residents realise), the invoice you keep must still be in your name and from the firm holding the accreditation. A back-to-back invoice between two firms is irrelevant to your deduction, but you do not want to discover that your only invoice is between two French entities and has nothing to do with you.
Worked example
A US resident sells an apartment in the 11th arrondissement of Paris for €620,000, bought in 2014 for €420,000. The accredited firm quotes a flat fee of €4,800. Allowable acquisition costs (notary fees on purchase plus a forfait of 7.5%) bring the adjusted cost basis to €451,500. Selling costs (diagnostics, agency split, fiscal representative fee) total €25,300, of which €4,800 is the representative fee. Gross gain after costs is €620,000 minus €451,500 minus €25,300, so €143,200. The income-tax base is €143,200 and the income tax CGT at 19% is €27,208. Social charges at 17.2% (US residents pay full social charges) are €24,630. Total €51,838.
If the seller had not deducted the €4,800 fee, the income-tax base would have been €148,000, the income tax €28,120, and the social charges €25,456. Total €53,576. The deduction recovered €1,738, or roughly 36.2% of the fee. The mandate fee paid in cash was €4,800; the after-tax cost was €3,062.
Pitfall to avoid
The classic mistake is letting the firm bill the notaire instead of you. The notaire then settles the invoice from the proceeds and charges you back. From your bank statement everything looks the same, but the invoice that ends up in the file is between the firm and the notaire, with the notaire as the customer. The 2048-IMM line gets rejected at audit because the seller was never invoiced. Always ask for the invoice in your name, request a PDF copy before signing the deed, and keep it for at least three years.
Pro tip
Negotiate the fee net of recovered tax, not gross. If the firm quotes €5,000 and you know the recovery on your file is around 33%, the after-tax cost is €3,350. That is the number to compare across firms, because it captures the real wallet impact and removes the noise from headline percentages. Ask the firm to write the after-tax estimate next to the headline fee on the mandate; firms that have done this calculation many times do it in seconds, and firms that hesitate are the ones whose headline number is the only number they have ever quoted.
Key takeaways
- The fiscal representative fee is deductible from the taxable gain on the 2048-IMM as a selling cost.
- Recovery is roughly 26.5% to 36.2% of the fee, depending on the social-charges rate that applies to you.
- Three conditions: invoice in your name, dated before the deed, effectively paid.
- Ask for the invoice in your name; never let the notaire be billed in your place.
- Compare firms on the after-tax cost, not on the headline percentage.
Frequently asked questions
Is the fiscal representative fee always deductible from the taxable gain?
In practice yes, when the fee is invoiced to the seller, paid before the deed, and supported by a proper invoice in the seller name. The deduction reduces both the income-tax CGT (19%) and the social charges (7.5% or 17.2%).
Where is the deduction declared on the 2048-IMM?
The fee belongs in the line that aggregates frais de cession (selling costs) on the form. Your representative fills it in, and the supporting invoice stays in the file in case of audit.
Can I deduct the fee if the firm pays it from the proceeds at completion?
Yes, provided the invoice predates the deed and is in your name. The mechanism of payment (offset against proceeds, bank transfer, escrow release) does not change deductibility, but the date of the invoice and the identity on it do.
How much do I save by deducting the fee?
Roughly 26.5% to 36.2% of the fee, depending on which social-charges rate applies to you (19% income tax + 7.5% or 17.2% social). On a €5,000 fee that is between €1,325 and €1,810 of recovered tax.
