Here’s the latest on tax filing deadlines (date limite impôt) for 2026, with a quick note on regional variations.
Top-line answer
- In France, the 2026 tax declaration campaign (revenus 2025) opens on April 9, 2026, with online filing available from that date; paper declarations have separate deadlines depending on your department and filing method. Ex: online deadlines vary by zone (departments 01–19, 20–54, 55–976) and typically extend into early June for the latest zones. The notices and payment schedules are generally published by the French tax administration in spring each year, so your exact cutoff depends on your department and whether you file online or by paper. For IFI (impôt sur la fortune immobilière) declarations, deadlines align with the income tax declaration window, with dates published per zone; the online service opens on April 9, 2026, and specific deadlines for online submission by zone are published similarly. In Canada, the Canada Revenue Agency (CRA) provides guidance for the 2026 tax period, including general readiness and filing expectations; check their updates for provincial nuances if you’re filing in Canada.[1][3][6][7][10]

Notes and practical tips
- Since exact deadlines vary by location and filing method, verify the precise dates for your situation on the official tax authority website or your tax advisor’s notice for 2026. The primary French deadlines and zone-based cutoffs are typically published in the spring and can differ between online and paper submissions.[3]
- If you file electronically as a professional using teleprocedure, an additional 15 calendar days may be granted, effectively shifting your practical deadline; this is a common extension path in practice for many filers.[2][3]
- If you’re unsure about which zone you belong to or whether you should file paper vs online, consult the impots.gouv.fr calendar or your local tax office for confirmation; the published timelines are zone-specific and can affect your exact deadline.[9][3]
Illustration (example scenario)
- A company with a December 31 year-end using teleprocedure would typically have the online filing open by April 9, 2026, with zone-based online deadlines; if you’re in Zone 1 (01–19 and non-residents), the deadline might be around May 21, 2026, while later zones push toward early June; the liasse fiscale submissions for corporate tax follow their own rules but are often aligned to the same spring window, with a typical deadline around early May to mid-May depending on the regime and filing method.[5][1]
Would you like me to pull the exact deadlines for your department (Los Angeles/CA or your French department if you’re filing in France) and summarize them in a concise checklist? If you’re filing in France, I can also generate a zone-specific deadline table once you confirm your department code. Please specify whether you need France-only guidance or Canada-focused timelines as well. Sources: French campaign details and deadlines, CRA guidance for 2026 and general readiness.[7][10][6][1][3]
