Should you be paying corporate tax in Luxembourg, and if so, how much?

This guide provides some key information to get you started.

If you run a business in Luxembourg, you may be liable for corporate income tax in Luxembourg (impot sur le revenu des collectivites in French). Businesses in Luxembourg also have to pay Communal Business Tax if profits are above a certain amount.

This guide provides information about the basics to get you started and ensure you avoid paying any unnecessary fines.

Who pays corporate tax in Luxembourg?

Corporate tax in Luxembourg is payable on business income not taxed through personal income tax. In Luxembourg, this applies to limited companies, including public limited companies, limited liability companies and partnerships limited by shares.

Business income that is made by freelancers, sole traders, and unincorporated partnerships will usually be taxed through personal income tax rather than corporate income tax in Luxembourg.

Companies subject to corporate tax in Luxembourg that are resident in Luxembourg pay tax on their worldwide income. Companies based abroad that operate in Luxembourg through a branch or subsidiary will pay corporate tax only on income generated in Luxembourg.

If you run a business or are self-employed in Luxembourg, whether your profits are taxed as personal or corporate income, you need to register with the Luxembourg Inland Revenue (Administration des contributions directes – ACD).

See our guide to taxation in Luxembourg for more information on who qualifies as a tax resident in Luxembourg.

Filing US taxes from Luxembourg

Despite the fact that every US citizen and Green Card holder is required to file a tax return with the IRS even when living abroad, many expatriates still fail to do so.
