French Non-Taxation Certificate Request Letter

Since 2020, the DGFiP abolished the paper certificat de non-imposition and replaced it with a single digital document: the ASDIR. It consolidates your entire tax position — declared income, revenu fiscal de référence, calculated income tax, and, where you owe nothing, an explicit line reading "income tax: €0." Virtually all French public bodies — the CAF, CROUS, prefectures, and social landlords — accept the ASDIR as a full substitute for the old paper certificate.

Log in to your espace particulier at impots.gouv.fr using your DGFiP credentials or via FranceConnect+ (linked to your national ID, Ameli health account, La Poste, or MSA). Go to "Documents," then select "Avis de situation déclarative à l'impôt sur le revenu." Choose the notice covering 2024 income. The timestamped PDF downloads instantly. If you have not yet created an espace particulier, you need your numéro fiscal (11-digit tax reference number on any DGFiP letter or old tax notice); activation is immediate by SMS or within 7 days by post.

Since the rollout of the système de ressources contemporaines (real-time income assessment system) in January 2021, the CAF updates your APL (aide personnalisée au logement — means-tested housing benefit) every three months by querying the DGFiP and URSSAF directly, so routine renewals rarely require a submitted document. The ASDIR is still required for foreign income, atypical self-employment, first-time applications outside the automated system, or when your caseworker explicitly requests it. It is fully recognised as equivalent to the former paper certificate.

In 2026, the ASDIR covers 2024 income declared in spring 2025 and processed by the DGFiP from autumn 2025. The revenu fiscal de référence (RFR) shown is the income base used by many organisations to calculate entitlements: CROUS student grants, APL, transport subsidies, mutual insurance social pricing, and HLM social housing committees. Its legal definition is set out in article 1417 of the Code général des impôts.

The espace particulier is the primary route and the only one offering instant access. If you cannot access the online service, visit your local centre des finances publiques (CDFP — public tax office) with a valid photo ID; a DGFiP agent can print your ASDIR on the spot at no charge. The DGFiP no longer sends attestations by post on simple request since the espace particulier became universal. Check your CDFP's opening hours on impots.gouv.fr before travelling.

Yes. The Dossier Social Étudiant (DSE — student social file, submitted on messervices.etudiant.gouv.fr) requires the revenu fiscal de référence for year N-2, meaning 2024 income for the 2026-2027 academic year. The ASDIR is the official document attesting that figure. Download it from your espace particulier and attach it as a digital file to your DSE. Verify that the ASDIR covers 2024 income (not 2023) — the reference year appears in the document header — to avoid rejection.
