Crypto Taxation in Luxembourg: The 6-Month Rule, Income vs Capital, Mining and Staking

Crypto taxation in Luxembourg does not sit in a special regime. The Administration des contributions directes (ACD) treats virtual currencies as intangible assets, so your bitcoin, ether or stablecoins are taxed under the ordinary rules for private and professional income. The decisive question is rarely "is crypto taxed?" but rather "how did you earn the gain, and how long did you hold the asset?"

This guide explains crypto taxation in Luxembourg for the 2026 tax year: the six-month speculative rule, the line between income and capital, how mining and staking are treated, and the record-keeping you need before you file.

Private wealth versus business activity

The first fork in the road is whether your crypto activity is private asset management or a commercial (business) activity. Occasional buying and selling from personal savings is normally private wealth management. But if you trade with high frequency, use leverage or borrowed funds, run mining hardware at scale, or act in an organised, business-like way, the ACD may reclassify your activity as commercial. Commercial profits are taxed as business income at progressive rates, and can trigger social contributions and, potentially, trade tax.

For most individuals, crypto stays in the private sphere, and that is where the six-month rule applies.

The six-month speculative rule

For private investors, the holding period decides everything.

• Held for six months or less: a disposal is a *speculative* transaction. The gain is taxable as "other income" at your ordinary progressive rate (up to about 42%, plus the 7%–9% solidarity surcharge).
• Held for more than six months: the gain from disposing of privately held crypto is generally tax-exempt for individuals, unless you hold a "major holding" in the relevant asset (broadly a stake over 10%, which is rare for currency-type tokens).

A disposal includes selling crypto for euros, swapping one token for another, and using crypto to pay for goods or services. Each swap is a taxable event that closes one holding period and opens another.

There is a helpful de minimis rule: if your total speculative gains across the year are below €500, they are exempt. Cross that threshold and the whole amount becomes taxable.

Because different lots have different acquisition dates, Luxembourg generally accepts a first-in, first-out (FIFO) approach to identify which coins were sold, provided you apply it consistently.

Mining and staking

Mining and staking rewards are treated differently from simple appreciation.

• Mining is usually seen as a commercial activity when carried out with dedicated hardware and intent to profit. The value of coins received is business income at the moment of receipt, and later disposal can produce a further taxable gain.
• Staking, lending and yield rewards are typically taxable as miscellaneous income at their market value on the day you receive them. If you then hold and later sell the received tokens, the six-month clock starts on the receipt date.

The practical trap is valuation: you must record the euro value at the exact time each reward lands.

Worked example

Suppose you are a private investor in tax class 1.

• In February you buy 1 ETH for €2,000.
• In May (four months later) you sell it for €2,600. Because you held it under six months, the €600 gain is speculative.
• In the same year you also sell bitcoin bought 14 months earlier for a €5,000 profit. Held over six months, that gain is exempt.
• Your total speculative gains for the year are €600, above the €500 threshold, so the full €600 is added to your taxable income and taxed at your marginal rate.

Had you sold the ETH one week later, past the six-month mark, the €600 would also have been exempt.

Record-keeping and how to declare

Exchanges do not file a Luxembourg tax statement for you. You are responsible for a complete transaction log.

Speculative gains and crypto-related income are reported in your annual income tax return (Modèle 100). Keep supporting records for several years in case of review, and consider portfolio-tracking software that exports a Luxembourg-friendly report.

Frequently Asked Questions

Do I pay tax if I only hold crypto and never sell? No. Merely holding crypto creates no taxable event in Luxembourg. Tax arises on disposal, and only if you disposed within six months (as a private investor) or the activity is commercial.

Is swapping one coin for another taxable? Yes. A token-for-token swap is a disposal of the first asset. If that asset was held six months or less, any gain is speculative and taxable; a new holding period starts for the token you receive.

Are stablecoins treated differently? No special regime applies. Stablecoins are intangible assets like any other crypto, so the same holding-period and income rules govern gains, swaps and rewards.
