Your French patrimoine, obligation by obligation
AdminLanding Editorial
Foreign accounts, real-estate wealth tax, succession, marital regimes — French patrimonial rules are dense. Describe your situation once and see exactly which forms and procedures apply, in plain English or French.
Quick answer
French tax residents carry several patrimonial reporting duties: every foreign bank, securities and life-insurance account is declared on Form 3916 and foreign crypto accounts on Form 3916-bis (Article 1649 A CGI; €1,500 per undeclared account, €10,000 in a non-cooperative State under Article 1736 IV). Households whose net taxable real estate exceeds €1,300,000 on 1 January owe the IFI, declared on annexe 2042-IFI (Articles 964–983 CGI). Succession is governed by the réserve héréditaire (Articles 912–913 Code Civil) and the default communauté réduite aux acquêts regime. AdminLanding's Patrimoine module is a rule-based diagnostic that tells you which of these apply, which forms to file and what to gather — it is information, not financial, tax or legal advice. Documents are produced in French; the interface is bilingual EN/FR.

Four modules, one diagnostic
Each answers a different question about your assets and returns a clear list of administrative steps.
Patrimoine diagnostic
Answer a few questions about your assets (real estate, investments, foreign holdings, family situation) and get the list of administrative obligations that apply to you.
Tax & declarations
Understand which reporting obligations follow from rental income, foreign income and capital gains — and which official forms and boxes they map to.
Estate & marital regimes
Plain-language guidance on succession planning, the réserve héréditaire and marital property regimes, with the steps and documents to gather.
Cross-border patrimoine
Foreign bank accounts, securities, life-insurance and digital-asset declarations (Form 3916 / 3916-bis) and international estate obligations.
The declarations that trip people up
Sourced from the Code Général des Impôts and the Code Civil — with the article behind each rule.
Form 3916 — foreign accounts
Every French tax resident must declare each bank, securities and life-insurance account held abroad (Article 1649 A of the Code Général des Impôts). Non-declaration is fined €1,500 per account, rising to €10,000 where the account is held in a State without an administrative-assistance agreement with France (Article 1736 IV CGI).
Form 3916-bis — digital assets
Accounts holding crypto-assets on foreign platforms are declared on Form 3916-bis, on the same annual return. The obligation exists whatever the balance; only the account, not each transaction, is reported.
IFI — real-estate wealth tax
The IFI applies when your household's net taxable real-estate assets exceed €1,300,000 on 1 January. It is declared with your income return on annexe 2042-IFI, on a progressive scale from 0.5% to 1.5% (Articles 964 to 983 CGI). Our diagnostic flags when the threshold may be in play — it does not compute or file the tax for you.
Succession & marital regime
French succession law protects a reserved share for children (réserve héréditaire, Articles 912–913 of the Code Civil), and the default marital regime is the communauté réduite aux acquêts (Article 1400 Code Civil). The module explains which rules apply to your situation and what to prepare before seeing a notaire.

A durable history that recalculates itself
Your patrimonial situation changes — a marriage, a purchase, an inheritance, a move abroad, a new child. The module keeps only your answers (never the report), so every saved analysis is re-run against the current rules when you open it. One tap re-plays your latest answers with the relevant question highlighted, and the new report shows what changed.

Important: AdminLanding is a technology platform, not a law firm, wealth manager or accountant. The Patrimoine module provides administrative guidance only — not financial, tax, legal or investment advice — and does not value your assets or file anything on your behalf. Figures and thresholds cited here reflect the rules in force on the date shown and may change; always verify on impots.gouv.fr and, for your specific situation, consult a qualified professional (notaire, avocat, expert-comptable).
