Personal Taxation in Luxembourg | Tax Scale
Introduction: A System in Full Mutation
The Grand Duchy of Luxembourg, a central player in European finance, carried out major fiscal adjustments in 2024 and 2025. The goal? To protect purchasing power against persistent inflation while maintaining the country's attractiveness for international talent. For residents and cross-border workers alike, understanding the progressive tax bracket scale and withholding tax mechanisms has become essential for sound private wealth management.
This guide analyzes in depth the new tax brackets, the impacts of indexation, and structuring strategies via transparent entities, all while drawing upon the most recent data from the Tax Guide.
Analysis of the Progressive Tax Scale (2024 - 2025)
The Luxembourg tax scale is composed of 23 brackets. In 2025, an indexation adjustment of 6.37% (representing 2.5 additional index tranches) was applied, following the 4-bracket adjustment already implemented in 2024. Here is the technical breakdown of this development for Class 1:
| Marginal Tax Rate | 2024 Bracket (in €) | 2025 Bracket (in €) |
|---|---|---|
| 0 % | 0 – 12,438 | 0 – 13,230 |
| 8 % | 12,438 – 14,508 | 13,230 – 15,435 |
| 9 % | 14,508 – 16,578 | 15,435 – 17,640 |
| 10 % | 16,578 – 18,648 | 17,640 – 19,845 |
| 11 % | 18,648 – 20,718 | 19,845 – 22,050 |
| 12 % | 20,718 – 22,788 | 22,050 – 24,255 |
| 14 % | 22,788 – 24,939 | 24,255 – 26,550 |
| 16 % | 24,939 – 27,090 | 26,550 – 28,845 |
| 18 % | 27,090 – 29,241 | 28,845 – 31,140 |
| 20 % | 29,241 – 31,392 | 31,140 – 33,435 |
| 22 % | 31,392 – 33,543 | 33,435 – 35,730 |
| 24 % | 33,543 – 35,694 | 35,730 – 38,025 |
| 26 % | 35,694 – 37,845 | 38,025 – 40,320 |
| 28 % | 37,845 – 39,996 | 40,320 – 42,615 |
| 30 % | 39,996 – 42,147 | 42,615 – 44,910 |
| 32 % | 42,147 – 44,298 | 44,910 – 47,205 |
| 34 % | 44,298 – 46,449 | 47,205 – 49,500 |
| 36 % | 46,449 – 48,600 | 49,500 – 51,795 |
| 38 % | 48,600 – 50,751 | 51,795 – 54,090 |
| 39 % | 50,751 – 110,403 | 54,090 – 117,450 |
| 40 % | 110,403 – 165,600 | 117,450 – 176,160 |
| 41 % | 165,600 – 220,788 | 176,160 – 234,870 |
| 42 % | Above 220,788 | Above 234,870 |
Crucial note: This rate is marginal. It only applies to the portion of income located within the defined bracket, which explains why the overall effective tax rate is always lower than the maximum marginal rate.
Understanding Tax Classes
The civil status of the taxpayer determines their "class," a multiplier that modifies the impact of the scale's progressivity:
- Class 1: Single, separated, or divorced individuals without dependent children.
- Class 1a: Widowed individuals, single parents with at least one child in the household, and taxpayers over the age of 65. This class benefits from higher tax thresholds.
- Class 2: Married couples or civil partners (pacsé) opting for collective taxation. Here, the Splitting mechanism applies: the tax is calculated on 50% of the couple's total income, and the result is then multiplied by two. This prevents the household's combined income from "jumping" too quickly into the 38% or 42% brackets.
The Solidarity Tax: The Employment Fund
Gross tax should not be confused with the net tax due. A surcharge known as the "contribution to the employment fund" (solidarity tax) is systematically added:
- 7 % of the tax due as a general rule.
- 9 % if taxable income exceeds:
- €150,000 for classes 1 and 1a.
- €300,000 for class 2.
Income from Movable Capital and Transparent Entities
Beyond salary, Luxembourg attracts through its management of investment income. Dividends paid by a Luxembourg company or an EU resident company are subject to a 15% withholding tax, but benefit from a 50% exemption in the majority of cases for individuals.
The Specific Case of SCSp and SCS
Limited Partnerships (SCS/SCSp) are increasingly popular. Since they are tax-transparent, they do not pay income tax at the corporate level. Profits flow through and are taxed directly at the individual partner level according to their progressive tax scale. This is a powerful tool for Private Equity, allowing for the consolidation of income while benefiting from the personal taxation rules of the country of residence.
Real Estate and Movable Capital Gains
The taxation of capital gains in Luxembourg distinguishes between short-term and long-term holding periods:
- Real Estate: The sale of the primary residence is entirely tax-exempt. For a secondary residence, if the property has been held for more than 2 years, the capital gain is taxed at "half the overall rate."
- Securities: Gains on shares are exempt if held for more than 6 months (for non-substantial participations < 10%). Below 6 months, the gain is considered a speculative profit and taxed at the standard progressive rate.
Tax Optimization Levers 2026
To reduce the taxable base, the Tax Guide authorizes several flat-rate or actual deductions:
- Pension Savings (Art 111 bis): Deduction of up to €3,200 per year, regardless of age.
- Insurance and Loans: Deduction of debit interest on personal loans and life insurance premiums (capped at €672 per person in the household).
- Home Savings (Épargne-Logement): Up to €1,344 for taxpayers under 40 years old.
The indexation of 2025/2026 has mechanically reduced the effective rate for the middle class. For example, a single person earning €50,000 gross will see their annual tax decrease by more than €300 compared to 2023, thanks to the favorable shift in the tax brackets.
