2026 French tax package deadline
Deadline for submitting the 2026 tax package: the official deadlines to know according to your closing date.
hayot-expertise.frHere’s a concise update on the 2026 date limite d’impôt.
- In France, the online filing window opened on 9 April 2026, with deadlines varying by department. The cutoff ranges from late May to early June 2026, depending on where you live (zones 01–19 and non-residents: around 21 May; zones 20–54: around 28 May; zones 55–976/976: around 4 June).[1][3][4]
- Paper declarations generally had an earlier deadline (around 19 May 2026) and are progressively used less as online filing dominates.[4][1]
- After filing, you typically receive your tax notices online between late July and late July 2026, with initial refunds possible on 24 or 31 July 2026, and any balance payable via one or four monthly installments from September to December 2026 (if applicable).[7][1][4]
- If your year-end closing differs, the basic rule is to file within three months of your fiscal year end, with an extra 15 days if teleprocedure applies; practical deadlines align with the general online window described above.[2]
Illustration: If your financial year ends on 31 December 2025 and you file online as part of Zone 1 (01–19), expect a deadline around 21 May 2026 and, later, tax notices in late July with any balance due payable starting September 2026.
If you’d like, I can tailor deadlines to your exact department (London is outside France, so you may be dealing with a different jurisdiction), or summarize the key changes announced for 2026 (rates, credits, etc.).
