Luxembourg Capital Gains Tax Guide 2026

Overview — Capital Gains Taxation in Luxembourg

Luxembourg distinguishes between speculative gains (short-term) and non-speculative gains (long-term) for capital gains tax purposes. The distinction depends on the holding period of the asset. Shares and other securities held for more than 6 months benefit from a full exemption. Real estate held for more than 2 years is also exempt. Short-term gains are taxed as ordinary income under the progressive IIT scale. This generous regime applies to individual investors and is one of the key attractions of Luxembourg as a wealth management jurisdiction.

Capital Gains on Shares — 0% if Held >6 Months

Capital gains from the sale of shares, bonds, and other securities are treated as follows:

• Held more than 6 months: Fully exempt from tax (non-speculative gain). No capital gains tax is due, regardless of the gain amount.
• Held 6 months or less: Taxed as ordinary income at the taxpayer's marginal IIT rate (progressive 0%–45.78%). The gain is added to other income on the annual tax return.
• Substantial participation (>10%): Gains from the sale of a substantial participation (direct or indirect holding of 10% or more) may be subject to specific rules. If the shares were held for more than 6 months, the gain may be exempt under the participation exemption for individuals (conditions apply).

The 6-month holding period is measured from the acquisition date to the disposal date. For inherited shares, the holding period of the deceased is generally carried over.

Capital Gains on Real Estate

Capital gains from the sale of real estate are subject to specific rules:

• Held more than 2 years: Exempt from tax (non-speculative gain)
• Held 2 years or less: Taxed as speculative income at progressive IIT rates (0%–45.78%)
• Principal residence: Gains from the sale of the main residence are fully exempt regardless of the holding period
• Calculation: Taxable gain = sale price minus acquisition cost (plus improvement costs and transaction expenses)

Corporate Capital Gains

For companies, capital gains are included in ordinary taxable income and taxed at the standard CIT rate (17%) plus MBT (resulting in an effective rate of approximately 24.94%–28.94%). However, the participation exemption provides 100% relief on gains from qualifying shareholdings (at least 10% or EUR 1.2 million acquisition cost, held for at least 12 months).

Cryptocurrency Gains

Luxembourg has not issued specific legislation for cryptocurrency taxation. The general capital gains rules apply:

• Crypto held >6 months: Likely exempt as non-speculative gain (applying the general securities exemption by analogy)
• Crypto held ≤6 months: Taxable as speculative gain at ordinary IIT rates
• Professional trading: If crypto trading constitutes a business activity, gains are taxed as business income (IIT for individuals, CIT for companies)
• Mining and staking: Likely treated as business income or miscellaneous income, subject to IIT

The Luxembourg tax authorities (ACD) have not issued formal guidance on crypto. Taxpayers should seek professional advice and consider filing conservative positions.

Loss Offsetting

Capital losses on speculative transactions can be offset against speculative gains in the same year. Net losses can be carried forward indefinitely (no time limit) and offset against future speculative gains. Losses cannot be offset against other types of income (employment, business, rental) or carried back.

FAQs

Is there really zero tax on shares held more than 6 months?

Yes, the Luxembourg tax law provides a full exemption for capital gains on securities held for more than 6 months. This applies to shares, bonds, ETFs, and other financial instruments. There is no limit on the gain amount. This makes Luxembourg one of the best jurisdictions in Europe for equity investors.

Does the 6-month rule apply to non-residents?

Non-residents are generally not subject to Luxembourg capital gains tax on securities, as the gains are considered foreign-source income for non-residents. However, non-residents with a permanent establishment in Luxembourg may be affected.

What is the tax treatment of options and derivatives?

Options, futures, and other derivatives are generally treated as securities. If held for more than 6 months from acquisition to disposal/expiry, gains are exempt. Short-term derivative gains (held ≤6 months) are taxable as speculative income.
