This page was last modified on 25-09-2017

Corporate income tax is a special proportional tax levied on gains made by certain corporations (including capital companies) during the financial year.

Who is concerned

Corporate income tax applies mainly to the following legal forms of capital companies:

Undertakings for Collective Investment (UCI) which collect savings from the public in order to make investments according to the principle of risk diversification (equities, bonds, etc.) are excluded from said tax. UCIs can take the following legal form of company structure:
  • SICAV – open-ended investment company, i.e. a public limited company whose particularity is the variable capital;
  • SICAF – closed-ended investment company, i.e. a public limited company with the exception of its investment policy.

How to proceed

Taxation in Luxembourg: the principle of territoriality

Given the territoriality of tax, only companies that have a sufficiently strong attachment with Luxembourg have unlimited tax liability.

This is valid for resident companies, i.e. a company who 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 who generates Luxembourg income is subject to limited tax liability.

Resident company

Resident companies are taxable on their worldwide income.

However, if the foreign income is collected in a country who has concluded a tax agreement with Luxembourg to eliminate double taxation, the foreign income will be exempt from Luxembourg tax if it was generated by a permanent establishment.

Non-resident company

Non-resident companies are only taxable on their local income in Luxembourg.

Applicable rates

Tax rate

Corporate income tax for resident and non-resident companies has been set at the following rate in 2013:

  • 20 % where the taxable income does not exceed EUR 15,000;
  • 21 % where the taxable income exceeds EUR 15,000.

An additional charge of 7 % is levied on corporate income tax as a contribution to the employment fund.

Amount of minimum tax

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.

Tax return and payment

Accounting and tax return obligations of the company

The company must declare its taxable income to the Luxembourg Inland Revenue (ACD) who will calculate the amount of tax due by the company and set the terms of payment.

Income tax return

In order to declare their taxable income, companies have to:

Tax return documents

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 return documents must include:

  • the balance sheet;
  • the profit and loss account;
  • table of fixed assets and depreciations;
  • the financial statements of the overhead expenses.

Payment of tax

Provisional advance payments

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.

Tax payable

The company receives back the tax return indicating the tax payable for the current financial year. The tax return shows the remaining balance 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. The reimbursement can:

  • be paid on the company's bank account;
  • be deducted from any other amount due by the company to the tax authorities (e.g.: the income tax claim can be deducted from the net wealth tax due).

Exemption

It is possible to submit a request for a tax exemption to the Luxembourg Inland Revenue.

Conditions

In order to benefit from a tax exemption, 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.

Duration and amount

Exemption is then granted for a period of 10 years and amounts to 25 % of the total profit of the business. It can not exceed 10 % of the investments made, nor a certain percentage of labour costs in relation to the permanent jobs which have been newly created.
