Cryptocurrency in Luxembourg: six months to a tax-free sale
In short. Luxembourg asks one question of a private crypto holder: how long did you keep it. Six months and a day, and the gain leaves no tax. Sell inside six months and the profit joins your income on the progressive scale, though the first 500 euros of speculative gain each year is exempt. The rule is older than crypto and applies to private wealth of other kinds too.

Six months, and the date you bought
Luxembourg does not tax a private person on disposing of private wealth held long enough. For movable property, crypto included, long enough means more than six months.
Buy in January and sell in August, and the profit is outside the charge. Buy in January and sell in May, and the gain counts as speculative: it goes into your income for the year and meets the progressive scale, which reaches about 42% before the solidarity surcharge.
The first 500 euros of speculative gain in a year is exempt. That is a threshold, not an allowance taken off a larger figure: exceed it and the whole speculative gain enters the calculation.
Two consequences follow for anyone holding here. Know the acquisition date of every lot, because the six-month line runs from it. And watch the order you sell in, since Luxembourg's treatment of which units left first decides whether a disposal landed inside or outside the window.
Private wealth, not business
The six-month rule belongs to the rules on private wealth management. Trade at a scale and frequency that makes the activity a business, and you leave those rules: profits become commercial income, taxed whatever the holding period, with social contributions on top.
No statute draws that line with a number of trades. Volume, borrowing, organisation and whether you act for others all weigh on it, in the same way they do in Malta.
Thirteen licences from a financial centre
The CSSF supervises crypto providers as Luxembourg's competent authority under MiCA. Thirteen firms hold authorisation here, behind Malta's twenty-three and ahead of Ireland's twelve.
That the number is high for a country of 680,000 people follows from what Luxembourg already is: a fund domicile with a regulator used to cross-border licensing, in a union where one authorisation serves all twenty-seven states.
What the CSSF said when the window shut
Luxembourg took the full eighteen-month transition, which ended on 1 July 2026. The CSSF published its position the next day.
Crypto services in the EU may be provided only by authorised firms. Anyone without a licence has to wind down in an orderly way: no new customers, no new accounts, no advertising, and nothing beyond helping existing clients convert, transfer to an authorised platform or move to their own wallet.
The regulator added a warning about reverse solicitation, the exemption that lets a firm outside the EU serve a customer who approached it unprompted. Some providers would stretch it to keep serving European customers, the CSSF said, and called that a risk for consumers.
Allowed
- Sell after six months with no tax, as a private holder
- Take 500 euros of speculative gain a year without tax
- Use any provider authorised under MiCA anywhere in the EU
- Hold crypto in a private portfolio without an annual charge on it
Restricted
- Applying the six-month rule to business activity: it covers private wealth
- Treating the 500 euros as a deduction from a larger gain, since it is a threshold
- Serving EU clients without authorisation, as of 1 July 2026
- Relying on reverse solicitation to use an unauthorised platform, which the CSSF flagged
How the rules took shape
The tax authority confirms that crypto follows the existing rules on private wealth.
The EU crypto rules take effect, with the CSSF as supervisor.
The transition ends and the CSSF orders unauthorised providers to wind down.
The CSSF warns that reverse solicitation is being stretched by firms outside the EU.
Thirteen authorised providers, with applications still before the regulator.
Worth knowing
When the transition closed, the CSSF told unauthorised providers they may no longer take on new customers, open accounts or advertise, and may only help existing clients leave. It also warned that some firms outside the EU would claim the reverse-solicitation exemption to keep serving customers here.
Common questions
When is my crypto gain tax free?
When you sell more than six months after buying, as a private holder.
What if I sell sooner?
The gain counts as speculative and joins your income on the progressive scale, which reaches about 42% before the surcharge.
What does the 500 euro figure do?
It is a threshold for the year's speculative gains. Stay under it and you owe nothing; go over it and the whole gain counts.
Does the six-month rule apply to active traders?
No. Trading at business scale produces commercial income, taxed whatever the holding period.
Can I use a platform without an EU licence?
The CSSF warned against it and said some such firms misuse the reverse-solicitation exemption.
