In short
Missing the deadline does not mean you cannot file. Consequences attach to the delay, but the situation only deteriorates the longer it is left — and the treatment can differ depending on whether you come forward or respond after being asked. Check National Tax Agency guidance and speak to the tax office or a tax professional as soon as you can.
Key points
- You can still file after the deadline; leaving it only makes things worse
- Coming forward yourself and responding after being asked can be treated differently
- Charges attach to the delay by design
- Where several years have piled up, involving a professional is the realistic route
Definition
A return filed after the statutory deadline. Filing remains possible, but the treatment differs from a timely filing.
Crypto returns run late for many reasons: not knowing a filing was required, not finishing the calculation, or the numbers being too large to face. Whatever the reason, the common thread is that time makes it worse.
The first thing to know is that filing is still possible after the deadline. Missing it does not close the door. Leaving the position unfiled, by contrast, lets the consequences of the delay accumulate.
And the treatment can differ depending on whether you come forward yourself or respond after the tax office raises it. In other words, acting once you realise has practical value. This site does not state the rates or amounts involved — take those from National Tax Agency guidance.
The first practical task is establishing the facts: which years are involved, which exchanges and wallets, and whether the history can still be retrieved. After some years an exchange may have shut down or passed its retention window. Collect whatever survives — deposit and withdrawal records, email notifications, even screenshots all count as material.
Where several years have accumulated, doing it all yourself is usually unrealistic, and judgement calls about how items fall across years enter the picture. At that point engaging a tax professional is faster and more reliable. Do not hesitate over the consultation itself.

Frequently asked questions
I did not know I had to file. Does that change anything?
Not having known does not remove the obligation. Whether you come forward once you do know, however, can bear on the treatment. Speak to the tax office or a tax professional as soon as possible.
