Filing deadlines, and the notes that catch people out.
A deadline on its own is rarely the whole story. Every entry here carries what the reference says about extensions, agent-filed dates and the difference between paper and online.

Online. The exact date depends on the department, so there is no single national date to publish — confirm yours with the DGFiP.
No single national date is published, so none is shown. Confirm your date with the tax authority.
30+ countries in the product. 10 on this page.
The product publishes standard individual income-tax return deadlines for more than 30 countries. The documentation names 10 of them, and those 10 are what this page shows.
Filling in the rest from general knowledge would be inventing dates on the one page where a wrong date costs somebody a penalty. A short calendar that is right is worth more than a complete one that is nearly right.
Variable dates are shown as variable
A country whose deadline is genuinely a range, or where confidence is low, is never given a date. It appears with its window and an instruction to confirm with the authority.
France: Late May to early June — Online. The exact date depends on the department, so there is no single national date to publish — confirm yours with the DGFiP.
Those entries are also excluded from the calendar export, because putting one in a calendar means picking a day.
Confirm the current year’s date.
Deadlines move when they fall on a weekend or a public holiday, and extensions are granted for reasons that vary by year. These are the standard dates; the one that applies to you is the one the authority publishes for the year you are filing.
This is decision support, not professional advice. The calendar export carries the same caveat on every event, because an event in somebody’s calendar outlives the page it came from.
