Losing a loved one is a painful ordeal that is, all too often, compounded by the burden of administrative and tax procedures. Among these obligations, the estate tax declaration (déclaration de succession) holds a central place and raises many questions, particularly regarding compliance with the legal six-month deadline. How does this countdown work? What are the consequences of a delay, and how can you avoid them? This comprehensive guide, written by the experts at AvocatAI, provides you with all the key information and legal answers to navigate this step with peace of mind.

The déclaration de succession (estate tax declaration) is a mandatory tax document that allows the tax administration to assess the deceased's estate on the day of their death and to calculate any potential droits de mutation à titre gratuit (gratuitous transfer duties, commonly referred to as droits de succession or inheritance taxes). Unlike the acte de notoriété (record of heirship) which establishes the list of heirs, the estate tax declaration has a purely tax-related purpose.
According to the rules of French tax law, and more specifically *Article 800 of the Code général des impôts (CGI / General Tax Code), filing an estate tax declaration is not systematic. It depends on the family relationship with the deceased and the amount of the gross estate assets (actif brut successoral* — the total value of the deceased's property before deducting debts):
It should be noted that the surviving spouse and the PACS partner bound by a pacte civil de solidarité (civil solidarity pact) are completely exempt from inheritance taxes under Article 796-0 bis of the CGI, but they are still required to file a declaration if the gross asset thresholds mentioned above are exceeded.

Compliance with deadlines is the cardinal principle in tax matters. *Article 641 of the Code général des impôts*** sets the rules for calculating deadlines for registering deeds and declarations of transfer by death.
For individuals who pass away in metropolitan France or in the départements d'outre-mer (DOM / overseas departments), the estate tax declaration must be filed within 6 months from the date of death. The deadline is calculated from date to date. For example, for a death occurring on March 15, the declaration must be filed no later than September 15 of the same year.
The legal deadline is extended to 1 year (i.e., 12 months) when the deceased passed away outside of France (abroad or in an overseas territory that is not a department). This extension aims to account for the increased complexity involved in searching for assets or heirs internationally.
In certain exceptional situations, the starting point of the 6-month period may be deferred:

Failure to respect the 6-month deadline (or 12-month deadline, as the case may be) exposes the heirs to financial sanctions from the tax administration. These penalties are proportional to the inheritance taxes due. If no inheritance tax is owed, the delay generally does not result in financial penalties, although the administration may still demand that the document be filed.
From the very first day of delay (i.e., the first day of the 7th month following the death), late payment interest (intérêt de retard) begins to accrue. Its rate is set at 0.20% per month of delay (i.e., 2.40% per year). This interest is calculated on the amount of inheritance taxes actually due.
If the delay persists, a tax surcharge (majoration) is added to the late payment interest according to the following scale:

To better understand the financial impact of a delay, here are two concrete simulations.
Jean passes away on January 10, 2024. He leaves his son, Pierre, as his sole heir. The net estate assets amount to €150,000. After applying the legal direct-line tax allowance (abattement) of €100,000 (provided for by Article 779 of the CGI), Pierre's taxable share is €50,000.
The amount of inheritance tax owed by Pierre is €8,194.
Sophie passes away on May 5, 2023 abroad. She leaves her assets located in France to her nephew, Marc. The taxable assets after the allowance generate inheritance taxes of €20,000.

To respect the 6-month deadline, it is essential to act methodically as soon as the death occurs. Here are the 5 key steps to follow:
1. Contact a notary without delay: Although hiring a notaire (notary) is not legally mandatory in all cases (it is mandatory if the deceased owned real estate, had made a will, or if there were prior lifetime gifts), it is highly recommended. Contact the notary's office within the first 15 days following the death.
2. Gather supporting documents: You or the notary must list the assets (bank accounts, real estate, vehicles, jewelry) and liabilities (unpaid invoices, outstanding loans, funeral expenses up to a limit of €1,500).
3. *Establish the acte de notoriété:* This official document lists the heirs and their respective rights in the estate.
4. Draft the estate tax declaration: This involves filling out specific tax forms (forms 2705, 2705-S, and 2706). The notary generally handles this drafting and the precise calculation of the taxes.
5. File the declaration and pay the taxes: The declaration must be filed with the registration service of the service des impôts des entreprises (SIE / business tax service) of the deceased's domicile, accompanied by the payment of the inheritance taxes.

Hiring a notaire is mandatory if the deceased's estate includes real estate (to draft the attestation de propriété immobilière / certificate of real estate ownership), if there is a will, or if the value of the estate is equal to or greater than €5,000 (to establish the acte de notoriété). For very simple, low-value estates without real estate, the heirs can draft and file the declaration themselves.
The tax administration can grant, under certain conditions and against guarantees (such as a mortgage), a payment credit. There is paiement fractionné (split payment — paying the taxes in several monthly installments over a maximum period of 1 or 3 years) or paiement différé (deferred payment — notably in the case of a transfer of bare ownership, where payment is deferred until the death of the usufructuary). These arrangements are subject to legal interest.
In principle, the declaration must be signed by all heirs who are jointly and severally liable for the payment of the taxes. However, the signature of a single heir is sufficient to validate the filing of the declaration with the tax administration, and this signature jointly binds the other co-heirs (except with regard to specific legatees).
Yes. If the delay is justified by circumstances beyond the heirs' control (serious illness, late discovery of a will, extreme complexity in finding an heir abroad), a request for a discretionary waiver (remise gracieuse) of late payment interest or surcharges can be sent to the tax administration. The granting of this waiver remains at the sole discretion of the tax authorities.
