Missing a tax deadline is one of the most avoidable — and most expensive — mistakes a crypto investor can make. And in 2026 there’s nowhere to hide: with DAC8, CARF and Form 1099-DA, tax authorities increasingly receive your exchange data automatically, so an undeclared gain is far more likely to surface.
This is the SafeTax crypto tax calendar: the annual filing deadline in each of the 19 countries we cover, the form your crypto goes on, and a link to the official source. Bookmark it — the dates recur every year.

A deadline missed is interest and penalties
Almost every country charges interest on tax paid late, plus a penalty for filing late — and several add a separate, earlier deadline to pay the tax even before the return is due (Ireland’s 15 December CGT payment is the classic trap). Extensions usually exist, but they must be requested before the deadline, not after. If you have past years to fix, most authorities treat a voluntary disclosure far more leniently than a gap they find themselves — especially now that CARF data is arriving.
How to read this calendar
- These are the recurring annual deadlines, grounded in each country’s official tax authority. The most-searched markets (US, UK, France, Germany, Spain, Italy, Netherlands, Portugal, Ireland, New Zealand) were checked against the authorities’ own current-year pages.
- Exact dates shift: weekends, France’s département zones, Italy’s moving deadline, reforms, and per-taxpayer dates all move things. Always confirm the exact current-year date — and any extension — at the official source linked in the table.
- Rows marked * vary the most (Belgium, Switzerland, Luxembourg, and the Nordics’ per-taxpayer dates). This is educational information, not tax advice.

Frequently asked questions
When is the crypto tax deadline in France?
Crypto is declared on your annual French income return (with form 2086 / 2042-C for gains). The online deadline falls in late May to early June depending on your département zone; the paper deadline is mid-May. Confirm the exact current-year date on impots.gouv.fr.
When do I file crypto tax in the US and the UK?
In the US, crypto goes on Form 8949 / Schedule D with your Form 1040, due 15 April (extension to 15 October). In the UK, it goes on your Self Assessment return — online filing and payment by 31 January, paper by 31 October, and you must register by 5 October if your gains exceed the annual threshold.
Do I need a separate crypto form?
Often yes. Spain has Modelo 721 for foreign crypto over €50,000 (filed 1 January–31 March); Italy uses Quadro RW for foreign holdings; Germany uses Anlage SO for §23 private sales; France uses form 2086; the US uses Form 8949. The table shows the form per country.
What happens if I miss the deadline?
You’ll generally owe interest on any late tax plus a late-filing penalty, and some countries have an earlier separate payment deadline. Extensions exist but must be requested in time. If you have past gaps, a voluntary disclosure is usually treated more leniently than one the authority finds — verify the rules with your national authority.
This calendar is general in nature and isn’t a substitute for personalised tax advice. Deadlines recur annually but exact dates shift (weekends, zones, reforms, extensions); always confirm the current-year date with the official source before you rely on it.
