Income Tax Brackets
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.
Who Pays Income Tax In Luxembourg?
Workers in Luxembourg are assigned a tax class based on their circumstances. The three tax categories are as follows:
1: Separately taxed married taxpayers, single people, and certain married non-resident taxpayers.
- 1a: Individuals over the age of 65, single parents with dependent children
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.

Employment Benefit Taxes
Employee benefits such as healthcare plans and pay reduction plans are often taxable. Benefits in kind are often valued at their market worth. However, some are valued as a lump sum.
The Luxembourg government implemented a tax policy in 2021 that allows employees to share in corporate profits. Bonuses are only excluded from individual income tax if they are within 25% of the employee’s gross basic annual wage.
Another recent tax reform affects highly skilled workers hired from abroad. To qualify for Luxembourg’s immigrant scheme 2023, an employee must earn a minimum annual basic income of €75,000 (down from £100,000 in 2022).
The worker must also be a Luxembourg resident, and their employment must not replace the talents of a local employee. If these conditions are met, they are eligible for a 50% tax exemption of up to 30% of the expatriate’s yearly basic pay.
Rental Income Taxes
In Luxembourg, those renting out their homes must pay tax on their net rental income. This is calculated by deducting permitted expenses from the monthly rent.
Insurance, property taxes, rental charges, depreciation (if applicable), and debt interest on a mortgage are all examples of expenses.

It’s critical to verify with the IRS or a certified tax adviser to see if these exemptions apply to your case.
Annual Tax Adjustment
It could be a good idea to think about using the annual adjustment procedure to alter your tax withholdings. The purpose of this technique is to figure out how much tax you owe depending on your total taxable income for the year.
