Do I have to declare and pay tax on my crypto gains?
It comes down to one thing: how long you had held your crypto. The circular L.I.R. No 14/5 of 26 July 2018 treats cryptocurrency as an asset, not a currency. For a private individual, a sale made more than 6 months after purchase is a private-wealth gain: tax-free. Sold within 6 months, it is a speculative gain, taxed at the progressive rate (up to 42 %). The costly myth is to treat the 500 € figure as an allowance. It is a threshold — if your yearly speculative gains reach 500 €, the whole amount becomes taxable, not just the excess. And the idea that "crypto is anonymous, so nothing to declare" is living its final years: automatic exchange of information is coming. The FIFO method sets the order of sales.
📋 The rules
- Cryptocurrency is an intangible asset, not a currency: the circular L.I.R. No 14/5 of 26 July 2018 sets its tax treatment.
- Sale more than 6 months after purchase (private wealth): the gain is exempt from income tax.
- Sale within 6 months: a speculative gain taxed at the ordinary progressive rate (up to 42 %, before the employment-fund surcharge).
- The 500 € exemption is a threshold (Freigrenze): once reached, it makes the entire speculative gain taxable, not merely the excess.
- The order of disposals is set, in principle, by the FIFO method (first in, first out).
🔓 Exceptions
- A regular, organised activity (heavy trading, mining, staking) can be reclassified as commercial profit, taxable and subject to social contributions.
- Being paid in cryptocurrency (salary, service) is taxable income as soon as it is received, at its value in euros.
- The 6-month rule applies only to private wealth; between professionals or within a company, different rules apply.
⚠️ Penalties & fines
Failing to declare a taxable gain is an incomplete return, or even tax fraud. The Direct Tax Administration can reassess the tax, claim the tax avoided, add late-payment interest and a surcharge, and go back several years. The real turning point lies elsewhere: anonymity is disappearing. Under the EU regime for crypto-assets and the automatic exchange of tax information (DAC8), platforms will report their clients' transactions to the tax authorities. A position kept "quiet" for years can therefore surface all at once. In serious cases, aggravated tax fraud is a criminal offence carrying a fine and imprisonment. Finally, without a paper trail of your purchases, proving you held for more than 6 months — hence the exemption — becomes very hard.

❓ Frequently asked
Do I pay tax if I hold my crypto for more than six months?
No: for a private individual, a gain made more than six months after purchase is private wealth and is exempt from income tax. It is short holding, under six months, that triggers taxation as speculation.
Is the 500 € figure an allowance?
No, and this is a common mistake: it is a threshold, not an allowance. If your yearly speculative gains reach 500 €, the entire amount becomes taxable, whereas below that figure nothing is taxed.
At what rate is a short-term crypto gain taxed?
It is added to your other income and taxed on the progressive scale, whose top marginal rate reaches 42 %, before the employment-fund surcharge. The effective rate therefore depends on all of your taxable income for the year.
Are mining and staking treated as a simple capital gain?
Not necessarily: carried on in a regular, organised way, they can be reclassified as commercial profit. That income is then taxed like a self-employed activity and may trigger social contributions.
Can the tax office know that I hold cryptocurrency?
Increasingly so: the EU framework requires platforms to report their clients' transactions to the tax authorities. The idea of lasting anonymity is over, and a late regularisation costs more than declaring voluntarily.
