An essential step in regularizing the transmission of assets, it raises many questions: Who must complete it? When? How to value assets and calculate registration fees? Are there any reductions applicable?

As an expert in wealth strategy and SEO, we have written this exhaustive guide of more than 1,200 words to explain to you step by step, with absolute clarity, how to declare an inheritance for taxes, optimize your taxation and avoid late payment penalties.

Who must declare an inheritance for taxes?

Contrary to popular belief, the opening of an inheritance does not systematically lead to the obligation to file a declaration with the tax administration. French law provides for cases of total exemption based on the gross inheritance assets and the relationship with the deceased.

Cases of exemption from inheritance declaration

You are exempt from subscribing and filing an inheritance declaration with the registration department of your tax center if you meet one of the following conditions:

In a direct line (children, grandchildren) or between spouses/PACS partners: The gross inheritance assets (the total value of the deceased's property before deduction of debts) is less than 50,000 euros, on the express condition that you have not benefited from unregistered donations or manual donations from the deceased.
For other beneficiaries (brothers, sisters, nephews, nieces, third parties): The gross estate assets are less than 3,000 euros.

If the estate does not include any property, or if the gross assets do not exceed these legal thresholds, the filing of the inheritance declaration is not required.

Mandatory declaration: in what cases?

As soon as the deceased's gross assets exceed 50,000 euros (for direct line heirs or surviving spouse) or 3,000 euros (for all others), the declaration becomes **strictly obligatory**. And this, even if after deduction of debts and application of personal allowances, the amount of inheritance tax to be paid amounts to zero.

What is the legal deadline for declaring an inheritance?

The French tax administration imposes very strict deadlines for registering the inheritance declaration and paying any duties. The starting point for this period is the exact day of death.

Death occurred in mainland France

If the death took place in mainland French territory, the heirs have a legal period of 6 months to file the declaration of inheritance and pay the associated inheritance tax to the competent tax office (generally that of the deceased's domicile).

Death occurring outside France or in the French Overseas Territories

Additional time is granted by the tax authorities in the following specific geographical cases:

The deadline is extended to 12 months (1 year) if the death occurred outside France (abroad) or if the deceased resided in an overseas department or territory and the heirs reside in mainland France (or vice versa).

What are the sanctions and penalties in the event of delay?

Exceeding these deadlines exposes you to financial sanctions from the Directorate General of Public Finances (DGFiP):

Late interest: Interest of **0.20% per month** (i.e. 2.4% per year) applies to the amount of duties due, calculated from the first day of the month following the expiration of the legal deadline.
Increase in fees: If the declaration is still not filed after formal notice from the administration, an increase of **10%** is applied from the 12th month following the death. This increase can increase to **40%** if the document is not sent within 90 days following receipt of a tax formal notice.

How to complete the inheritance declaration (Forms 2705 and 2706)?

The formality of the inheritance tax declaration is technical. It is carried out using regulatory forms which must be completed with extreme precision to avoid any tax adjustment for omission or undervaluation.

The main form 2705 (SD)

The **Cerfa 2705-SD** form constitutes the centerpiece. It is on this document that you must provide the complete civil identity of the deceased, the heirs, the legatees (beneficiaries of a will), as well as the testamentary provisions or previous donations made by the deceased during his lifetime.

Annex forms 2705-A and 2706

Cerfa 2705-A-SD: It is mandatory if the deceased had taken out life insurance policies. This form allows you to declare the amounts paid to beneficiaries and to determine the possible taxable portion (particularly for premiums paid after the insured person turns 70).
Cerfa 2706-SD: It serves as a summary sheet for the precise calculation of the registration and inheritance rights owed by each heir after reduction.

You can download all of these forms and consult the explanatory notes directly on the official portal of the French tax administration: Declare an inheritance on Impots.gouv.fr.

Evaluation of estate assets and liabilities

The declaration must provide a sincere and detailed inventory of the deceased's assets on the day of his death. We distinguish:

Inheritance assets (property): It includes real estate (houses, land valued at their real market value), furniture (estimated by notarized inventory or legal flat rate of 5%), bank assets (current accounts, savings accounts blocked on the day of death), vehicles, jewelry and copyright.
Inheritance liabilities (debts): You must include all the personal debts of the deceased existing on the day of death (current credits, taxes due, pending energy bills). Funeral expenses are also deductible from assets for their actual amount, within the strict limit of 1,500 euros.

Net taxable assets (the basis for calculating taxes) are obtained by subtracting total liabilities from gross assets.

Deductions and calculation of inheritance tax: how much will you pay?

Once the net taxable assets have been determined, the share accruing to each heir is calculated. The State then applies a tax scale after deduction of a personal allowance which directly depends on your degree of relationship with the deceased person.

Deductions depending on the relationship

The tax reduction is tax-free: you only pay inheritance tax on the portion of the inheritance that exceeds this amount. In 2026, the reductions in force are as follows:

Spouse or PACS partner: Total exemption from inheritance tax (TEPA law). No tax to pay, whatever the amount inherited, although the inheritance declaration remains required if the asset thresholds are crossed.
Children and parents (direct line): An exceptional reduction of 100,000 euros per living or represented child. This reduction is renewed every 15 years.
Brothers and sisters: A reduction of 15,932 euros (with cases of total exemption under certain conditions of age, singleness and prolonged cohabitation with the deceased).
Nephews and nieces: A reduction of 7,967 euros.
Grandchildren: A specific allowance of 1,594 euros (unless they represent their deceased parent, in which case they share the allowance of €100,000).
Disabled people: An additional and cumulative reduction of 159,325 euros, regardless of the relationship.
Third parties (unrelated people): A minimal reduction of 1,594 euros.

The progressive scale of direct line inheritance taxes

On the taxable portion after deduction, a progressive scale in installments applies for direct line heirs (children):

Taxable portion after deduction	Applicable tax rate
Less than €8,072	5%
Between €8,072 and €12,109	10%
Between €12,109 and €15,932	15%
Between €15,932 and €552,324	20%
Between €552,324 and €902,838	30%
Between €902,838 and €1,805,677	40%
Greater than €1,805,677	45%

For distant relatives or unrelated third parties, taxation is much heavier: the flat rate tax rate is **55%** for relatives up to the 4th degree, and rises to **60%** for third parties and unmarried or civil partners.

Do you have to go through a notary to declare an inheritance?

This is a recurring question when settling an inheritance. Is the use of a ministerial officer (the notary) required by law to make tax declarations?

When is recourse to a notary obligatory?

You are **legally obliged** to entrust the settlement of the estate and the drafting of the declaration to a notary in the following four situations:

Presence of real estate: The notary must draw up a real estate certificate of ownership to officially transfer the property to the land registration file.
Inheritance assets equal to or greater than 5,000 euros: The notary must draw up an act of notoriety to officially prove the status of heir of the various beneficiaries to the banks.
Existence of a will: The notary must open, record and read the deposited will.
Presence of a donation between spouses (or “donation to the last living person”) or a previous donation made by the deceased during his or her lifetime.

Can you file your inheritance declaration yourself?

If the estate does not include **any real estate**, the assets are **less than 5,000 euros**, and there is **no will or previous donation**, the heirs can legally choose to draw up, sign and file the inheritance declaration themselves with the tax administration without going through a notary. It is a free process which saves notary fees.

Conclusion and final checklist of procedures

Declaring an inheritance for taxes requires rigor and absolute compliance with legal deadlines. To ensure you complete your procedures with complete peace of mind, here is a quick checklist of the key steps to validate:

✔️ Identify the need to declare: Check if the gross assets exceed €50,000 (direct line/spouse) or €3,000 (other heirs).
✔️ Monitor the calendar: Submit the declaration within 6 months following the death (if occurring in France) or 12 months (if occurring abroad).
✔️ Gather supporting documents: Death certificate, family record books, certificates of bank balances on the day of death, property titles, invoices for deductible debts.
✔️ Complete the Cerfa vouchers: Use the main form 2705-SD, possibly supplemented with 2705-A-SD (for life insurance) and 2706-SD (for the calculation of rights).
✔️ Request a professional if necessary: Do not hesitate to call on a notary or a tax lawyer if the assets include real estate complexities, assets abroad or family tensions.

By carefully planning these steps, you will protect the memory of your loved ones while best preserving your family heritage from financial penalties.
