Has your child gotten into Bitcoin? This practice, common among young people, directly engages your tax liability. In tax law, a minor child is in fact attached to the tax household of his parents. This rule can extend to adults up to 21 years old, and up to 25 years old if they are students. Any transaction carried out by your children must therefore appear in your income tax return.
Two obligations are required. First, any account opened on a foreign crypto platform must be declared each year via form 3916-bis. The omission costs a fine of 750 euros per account, increased to 1,500 euros if its value exceeds 50,000 euros. Then, any transfer of crypto-assets (conversion into euros or exchange for property) must be reported on form 2086. Capital gains are subject to the flat tax of 30% (31.4% on transfers in 2026 to be declared in 2027).
In case of forgetting… Increases apply: 10% for delay, 40% for deliberate failure. Many parents, unaware of their children’s digital practices, are exposing themselves to adjustments. The moral: talk crypto with your teenagers, your statement depends on it!
