Corporate income tax (impôt sur le revenu des collectivités - IRC) is a special proportional tax levied on gains made by certain corporations (including capital companies) during the financial year.
Capital companies are fiscally opaque, i.e. as corporate entities, they are taxpayers and subject to the tax on companies called corporate income tax.
Corporate income tax applies mainly to the following legal forms of capital companies:
Given the territoriality of tax, only companies that have a sufficiently strong connection with Luxembourg have unlimited tax liability.
This is valid for resident companies, i.e. a company that has its registered office or centre of effective management in Luxembourg.
Non-resident companies, i.e. a company whose registered office is not in Luxembourg but that generates Luxembourg income is subject to limited tax liability.
Resident companies are taxable on their worldwide income.
However, if the foreign income is collected in a country which has concluded a tax agreement to eliminate double taxation with Luxembourg, the foreign income will be exempt from Luxembourg tax if it was generated by a permanent establishment.
Non-resident companies are only taxable on their local income in Luxembourg.
Corporate income tax for resident and non-resident companies has been set at the following rate in 2019:

Companies subject to corporate income tax make provisional advance payments every quarter on the settlement dates laid down by law (March, June, September, December). The amount of these advance payments has been provisionally set based on the last tax return (from the previous financial year) and automatically adjusted upon request from the company, where applicable.
The company receives back the tax return indicating the tax payable for the current financial year. The tax return shows the remaining balance due taking into account the provisional payments made and the payment deadline (usually one month after receipt of the tax return).
Sometimes the balance is negative; i.e. the company has a claim against the tax authorities. In this case, the reimbursement can:
In order to benefit from a tax exemption on a share of the profits, businesses must set up new establishments or develop new processes which are known to contribute to the structural development and improvement of the economy, to the development of the regional economy or to a better geographical distribution of economic activities.
The exemption est usually limited to a duration of 8 years and 25 % of the profits for new businesses or new processes. It is also limited in relation to a certain percentage of the investments and expenses.
