SITUATION: CORONAVIRUS / COVID-19
In the context of the coronavirus pandemic, the Government has put in place a number of measures to support taxpayers, whether they be legal entities or natural persons.
For more information, please consult our news item on the subject.
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:
The following legal forms must also file a corporate income tax return using the template in .PDF format.
Each type of capital company has specific characteristics with regard to the setup of the business, its partners, management and taxation.
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:
An additional charge of 7 % is levied on corporate income tax as a contribution to the employment fund.
In some cases, businesses are subject to the payment of a minimum tax where the amount set is based on the closing balance in their last annual accounts.
The company must declare its taxable income to the Luxembourg Inland Revenue (ACD) that will calculate the amount of tax due by the company and set the terms of payment.
Corporate entities are in principle required to submit an online declaration for corporate income tax with the online assistant on MyGuichet.lu.
From 4 June 2020, a first version of the MyGuichet.lu procedure is available only for resident companies that did not belong to an integrated group during the operating year.
A full version of the procedure will be available soon.
The various fields in the assistant can be automatically completed by importing a structured XML file.
Corporate entities excluded from the mandatory online filing must continue to submit their declaration in paper format. These entities are:
Depending on the company's activity and the applicable tax scheme, the tax return must be submitted together with the accounting documents that have been used to calculate the company results.
In any case, the tax documents must include:
The Luxembourg Inland Revenue reserves the right to request additional supporting documents as part of the process of verifying any information, statements, applications, declarations, claims or appeals submitted to its offices.
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 is 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.
