Notre accompagnement
The liquidation of a Luxembourg company triggers multiple tax obligations and potential tax liabilities. Understanding these implications in advance allows for proper tax planning that can significantly optimize the outcome for shareholders. Our tax specialists cover all aspects: corporate income tax (IRC), withholding tax on the liquidation bonus, VAT deregistration, and social security obligations.
Corporate Income Tax (IRC) on Liquidation
The Luxembourg corporate income tax rate is 17% (for 2026, companies with taxable income above €200,001). During the liquidation period, the company remains subject to IRC on any profits realized. The liquidation period runs from the date of dissolution resolution until the final close. A final tax return covering the last open fiscal year plus the liquidation period must be filed with the Administration des Contributions Directes (ACD). Any remaining tax balance must be paid before the company can be struck off.
Withholding Tax (Retenue à la Source) on Liquidation Bonus
The liquidation bonus is the amount distributed to shareholders above the paid-up capital and share premiums. Under art. 97 LIR, the liquidation bonus is assimilated to a dividend and subject to a 15% withholding tax for Luxembourg-resident shareholders. For non-resident shareholders, the rate may be reduced under applicable double tax treaties (DTTs): e.g., 5% for French shareholders holding >25%, 0% for certain EU parent companies meeting the Parent-Subsidiary Directive conditions (holding ≥10% for ≥12 months).
VAT Deregistration (AED)
A company in liquidation must file a final VAT return covering the period from the last return to the dissolution date. All input VAT claims must be submitted before deregistration. Any VAT credit balance will be refunded by the AED (Administration de l'Enregistrement, des Domaines et de la TVA) within 3-6 months. The company must also cancel its VAT registration number with the AED.
Municipal Business Tax (ICC) Implications
The Impôt Commercial Communal (ICC) is levied at the municipal level on the company's business income. The rate for Luxembourg City is 6.75% on top of the IRC base. During liquidation, ICC continues to apply to business profits realized. The company must file a final ICC declaration and pay the tax before the company is deregistered.
Net Wealth Tax (Impôt sur la Fortune)
Luxembourg companies with assets exceeding certain thresholds are subject to net wealth tax (0.5% or 0.05% above certain thresholds). During liquidation, the net wealth is assessed at the start of each calendar year. If the company is fully wound up during the year, a pro-rata assessment may apply. Proper timing of the liquidation closing can minimize this charge.
Questions fréquentes
What is the withholding tax rate on liquidation bonus in Luxembourg?
The standard rate is 15% for Luxembourg-resident shareholders. For non-resident shareholders, the rate depends on the applicable double tax treaty. EU parent companies owning at least 10% for 12+ months may benefit from full exemption under the EU Parent-Subsidiary Directive. In the absence of a treaty, the 15% rate applies.
Can the liquidation bonus withholding tax be avoided legally?
Yes, in certain circumstances. EU parent companies meeting the Parent-Subsidiary Directive criteria are exempt. Companies holding shares in a Luxembourg entity through a qualifying holding structure may restructure before liquidation. Note that Luxembourg has anti-abuse provisions that can deny treaty benefits if the sole purpose of a structure is tax avoidance.
When must the final tax return be filed after liquidation?
The final IRC and ICC returns must be filed within the standard deadline (currently by June 30 of the year following the tax year). For the liquidation period, a special return covering the period from the last accounting period to the close of liquidation must be filed within 5 months of the close of the liquidation.
Is the liquidation bonus taxed differently from regular dividends?
In Luxembourg, the liquidation bonus is treated as a deemed dividend (assimilé au dividende) and subject to the same 15% withholding tax. However, the portion representing a return of paid-up capital and share premiums is not considered a dividend and is not subject to withholding tax - this is why the distinction between capital and accumulated profits is important.
What happens if the company has tax losses at the time of liquidation?
Luxembourg companies can carry forward tax losses for unlimited periods. These accumulated losses can offset any profits realized during the liquidation period (capital gains on assets, etc.). If losses exceed profits, the remaining losses cannot be distributed to shareholders but expire at the end of the liquidation.
