Income Tax Brackets

Income Tax Brackets In Luxembourg 1

Income tax is paid in Luxembourg by everyone who receives any income, not just salaries; this can include the net revenue from renting out property in Luxembourg or investment income.

Although there are various types of taxable income, each with its characteristics, taxes are generally based on a progressive income tax system. A progressive income tax rate framework indicates that the more you earn, the more taxes you pay.

Luxembourg’s Income Tax System

  • Expats must pay income tax on their earnings in Luxembourg, whether they work for an organization or are self-employed. Residents must pay tax on their worldwide income, whilst non-residents must only pay on income obtained in Luxembourg.
  • Workers are assigned a tax class depending on their marital and residency status, which determines how much income tax they pay, along with their wages.
  • Regular taxpayers in Luxembourg typically have their income tax contributions deducted from their paychecks. 

However, they must still file an income tax return with the Luxembourg Inland Revenue (Administration des Contributions directes – ACD) to confirm they are paying the necessary amount. This is known as assessment taxation.

  • Some self-employed taxpayers are required to make advance quarterly payments. These payments are made during the tax year in March, June, September, and December.

Since 2018, married couples have been able to choose between separate and joint taxation.

1: Separately taxed married taxpayers, single people, and certain married non-resident taxpayers.

2: Married taxpayers, widowed taxpayers (during the first three years following the spouse’s death), divorced or separated people (for the first three years), civil partners, and some married non-resident taxpayers.

3: Non Resident Taxpayers, Since non-residents are not entitled to the same deductions as resident taxpayers, the classification system may result in varying income tax bills for residents and non-residents.

Non-residents who earn more than 90% of their global income in Luxembourg or less than €13,000 outside of Luxembourg may choose to be considered residents.

On the other hand, Belgian citizens need to earn half of their professional income in Luxembourg to be eligible.
