Luxembourg tax system: Learn everything you need to know about taxes in Luxembourg, including income tax, tax law and the tax authority, plus how to file a tax return and get a VAT number.

This guide to Luxembourg’s tax system includes:

Resident or non-resident?

Luxembourg residents are required to declare their worldwide income, and non-residents of Luxembourg are taxable on their Luxembourg income source only. A resident tax payer means you have been living in Luxembourg for longer than six months consecutively, and short periods of leave are not taken into account.

Non-resident taxpayers refer mostly to the large amount of Luxembourg’s workforce that commutes into the country from bordering countries like France, Germany, and Belgium. It can also refer to a newcomer to Luxembourg within the first six months.

Check with your country of origin on their tax treaty that will either require or exempt double taxation laws, or what paperwork is required to avoid it.

Who is taxed in Luxembourg?

A taxable unit in Luxembourg is a family’s income including husband, wife, and children under the age of 18 years old. This does not mean the income of a child is taxed, but the possibilities for tax breaks from having a child is taken into account.

If one spouse is a resident and the other is not they will be taxed separately instead of jointly (joint income tax rates are generally lower for married couples, same sex marriages included). If you are in a partnership but not married, it is possible to elect to be covered as a joint income if one of the partners (or the non-resident partner) generates 90% or more of their total income in Luxembourg. You must be sharing the same residence in Luxembourg for at least one full year before applying.

Highly Skilled Workers tax regime

If you are living in Luxembourg as a highly-skilled international who has been recruited abroad by your company, you are entitled for the impatriate tax regime. You must be a Luxembourg resident, or not live more than 150 kilometers away from the Luxembourgish border, have been employed based on skills that are not replacing another local employee, and earn a minimum annual salary of €50,000.

A few more conditions must be met, but the advantage is to be able to expense costs such as relocation, school fees, rent and utilities, and even home leave of one trip per year. If you think you might be eligible for the impatriate tax regime, talk to your employer about applying.

Income tax

Luxembourg income tax comes from income from your own business, from employment, from pensions, investments, rentals, and other miscellaneous items like private assets, capital gains and casual services. If you work in Luxembourg, you will have to pay income tax and follow the Luxembourg income tax law.

Capital gains on the disposal of assets held by individuals are taxable as miscellaneous income. The tax varies according to whether the asset is sold within or after a minimum holding period. There are short-term gains and long-term gains, and exemptions when moving to new dwellings for professional or family reasons.

These income tax categories are added up to determine your net total income, then reduced by applicable deductions to determine your taxable income. There are several online Luxembourg salary calculators that can assist in finding personal taxable salaries in Luxembourg by just plugging in the relevant figures. Two examples include:

Tax benefits Luxembourg

There are over 20 income tax brackets that vary from zero to 42%. The balancing out of income tax rates also depend if the individual is single, married, divorced or widowed, with or without children, and over 64 years of age or not.

These tax cards are issued automatically up to 30 days after registering at the social security office (which is mandatory when registering in Luxembourg). A new tax card is applicable in case a resident changes address and civil status, but it’s up to the resident to announce this to the authorities via specific tax form.

  • Pension earners receive a tax credit of €300 a year.

Tax filing deadlines

The tax year ends 31 December every year in Luxembourg, and a taxpayer must file their return by 31 March the following year. Late filings that do not go past a few months are usually accepted.

However, a late filing penalty can amount up to 10% of your final tax amount or fines up to €1,250. Quarterly taxes are due on 10 March, 10 June, 10 September, and 10 December.

Which tax return do I need to submit?

When filing your income tax return in Luxembourg, you’ll either have to fill out Form 100 (a standard tax return) or form 163 (an annual statement, or décompte annuel).

If you’re an unmarried, salaried employee earning less than €100,000 (with no income from other sources), you’ll be able to file the more simplified annual statement, rather than a full tax return.

If, however, your taxable household income is above €100,000 or someone in your household has an income from more than one source, you’ll need to submit a full return (Form 100)

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. Many are unaware of these obligations, thinking that as an expat they do not need to pay or file tax returns in the US. You do!
