Luxembourg salary calculator 2026: from gross to net

From gross to net in Luxembourg: three deductions and a class

A Luxembourg payslip takes three things away from the gross salary. First, social security: about 12.95% for most employees, capped for the pension and health parts. Second, income tax, withheld every month under a progressive scale that runs from 0% to 42%. Third, a surcharge on that tax for the employment fund, 7% or 9%. A set of tax credits is then paid back through the same payslip.

The single number that changes the result most is the tax class. A single person in class 1 earning EUR 80,000 keeps about EUR 54,200 a year. A married colleague on the same salary, whose spouse has no income, keeps about EUR 63,700 in class 2. Same employer, same gross, nearly EUR 9,500 apart.

This guide walks through the 2026 rules in the order a payroll provider applies them, with examples at EUR 50,000, EUR 80,000 and EUR 150,000, and a calculator for your own figure. The numbers are for a resident employee. Cross-border workers pay the same Luxembourg social security and, in principle, the same tax, but their class and telework days follow their own rules.

Employee contributions in 2026

Luxembourg social security is a percentage of gross pay, withheld by the employer and paid to the Joint Social Security Centre (CCSS). The pension and health contributions stop at a ceiling of five times the social minimum wage. The dependency insurance contribution has no ceiling, but the first slice of pay each month is exempt.

The pension rate went up on 1 January 2026, from 8% to 8.5% for both the employee and the employer, as part of the pension reform. The minimum wage, and with it the ceiling, rose by 2.5% on 1 June 2026 when the latest index tranche fell due.

The ceiling matters for higher salaries. Above about EUR 166,000 a year, only the 1.4% dependency contribution keeps growing. At EUR 150,000 the employee pays about EUR 19,300 in total, or 12.9%. At EUR 250,000 the share falls to about 9%.

Every euro of social security an employee pays is deductible from taxable income, so the tax is computed on pay after contributions. That is why a gross salary of EUR 80,000 becomes a taxable income of about EUR 68,700 once contributions and the standard allowances are taken off.

Law and practice: Social Security Code (health, pension and dependency insurance chapters); social parameters published by the IGSS for 1 June 2026 (index 992.24, minimum wage EUR 2,771.33 a month for an unqualified worker aged 18 or over, ceiling EUR 13,856.63). The pension contribution rate of 25.5% in total, split equally between employee, employer and the state, applies from 1 January 2026.

The 2026 tax scale and the three tax classes

Luxembourg income tax is progressive. In class 1 the first EUR 13,230 of taxable income is tax-free; the rate then climbs by one or two points for every EUR 2,205 to EUR 2,295 of income, reaching 38% at about EUR 52,000 and 39% from EUR 54,090. It then rises in three wide bands to 42% above EUR 234,870.

The scale applied in 2026 is the one adapted from tax year 2025, when the brackets were widened by the equivalent of 2.5 index tranches. No new scale was legislated for 2026, so the 2025 brackets still apply this year.

The tax is then increased by the contribution to the employment fund, usually called the solidarity surcharge. It is 7% of the tax, or 9% when taxable income exceeds EUR 150,000 in classes 1 and 1a or EUR 300,000 in class 2. At the top, 42% plus 9% of 42% gives a marginal rate of 45.78%.

Class 1 applies to single people without children, to divorced or separated people more than three years after the separation, and to non-resident couples who do not ask to be treated as residents. Class 1a applies to single parents with a child in the household, to taxpayers aged 65 and over, and to widowed people more than three years after the death. It has its own scale, with a tax-free band of about EUR 26,460 and steeper rates afterwards that catch up with class 1 at around EUR 52,000. Class 2 applies to married couples and to partners registered for more than a year who live together, and for three years after a divorce or the death of a spouse.

Class 2 works by splitting. The couple's combined taxable income is halved, the class 1 scale is applied to each half and the result is doubled. A household with one salary therefore uses two tax-free bands and two runs of the lower brackets. With two equal salaries, splitting gives little extra, which is why the planned reform hurts two-income couples least.

The single tax class from 2028. Bill No. 8676, presented by the government on 6 January 2026 and amended in July 2026, proposes to replace the three classes with one scale, called Tarif U, from tax year 2028. Each person would be taxed on their own income, and the tax-free band would double to EUR 26,650. Couples married or partnered before 1 January 2028 could keep joint taxation under a transitional scale until the end of 2052, or opt irrevocably for the new one. It is a proposal: the brackets and the transitional rules can still change before the vote.

Law and practice: Income Tax Law (LIR), Chapter VII on the calculation of the tax (scale and tax classes, Articles 118 and following) and Article 157ter (non-residents); the law adapting the scale by 2.5 index tranches from tax year 2025; the employment fund contribution levied on the income tax. Bill No. 8676 on the single tax class, government amendments of 22 July 2026, pending before the Chamber of Deputies.

Tax credits and standard allowances

Before the scale applies, the employer deducts standard allowances from the salary: EUR 540 a year for employment expenses and EUR 480 a year for special expenses (EUR 960 for a couple in class 2). Employees with real expenses, a long commute, a private pension or insurance premiums can claim more in a tax return or through an adjusted tax card.

After the scale, three credits reduce the tax. They are paid through payroll, so an employee whose credits exceed the tax receives the difference with the salary.

• Salaried worker credit (CIS). EUR 600 a year for a gross salary between EUR 11,266 and EUR 40,000. It falls by 1.5% of the salary above EUR 40,000 and disappears at EUR 80,000.
• CO2 credit for employees. EUR 216 a year from 2026, up from EUR 192, to offset the higher carbon tax on fuel. It tapers between EUR 40,000 and EUR 80,000 of gross salary, like the CIS.
• Single-parent credit (CIM). Up to EUR 3,504 a year for taxpayers in class 1a with a child in the household, reduced gradually between EUR 60,000 and EUR 105,000 of adjusted taxable income to a floor of EUR 750. Maintenance received for the child above a threshold reduces it.
• Minimum wage credit. For full-time salaries close to the minimum wage, a monthly credit makes sure that low earners keep more of each pay rise.
• Deductions worth claiming. Private pension contracts up to EUR 4,500 a year from 2026, insurance premiums and consumer loan interest up to EUR 900 per person, mortgage interest on the main home, commuting costs and childcare.

The credits matter most at the bottom of the scale. For a salary of EUR 50,000 the CIS and the CO2 credit together are worth about EUR 660 a year. From EUR 80,000 they are worth nothing, and the tax is the scale alone.

Law and practice: LIR Article 154ter (CIM) and the provisions on the salaried worker and CO2 credits; amounts and formulas from the Luxembourg Inland Revenue (ACD) pages on the CIS and CI-CO2 from tax year 2026 and the CIM from tax year 2025. The 2026 increases of the private pension and insurance premium ceilings come from the 2026 tax package.

Net salary at EUR 50,000, EUR 80,000 and EUR 150,000

The table shows a resident employee paid twelve equal monthly salaries in 2026, with the standard allowances and the credits included. Class 2 assumes that the spouse or partner has no income of their own. The figures are rounded and use the same method as the calculator further down.

Three things stand out. First, the class 1 employee at EUR 50,000 pays more in social security than in tax; at EUR 150,000 tax is more than double the contributions. Second, the class 2 advantage grows with income in euros, from about EUR 3,700 to about EUR 13,400, because splitting keeps more of the income out of the 39% to 42% bands. Third, the total deduction at EUR 150,000 in class 1 is about 40% of gross: high, but below the Belgian and Dutch levels for the same pay.

A thirteenth month changes the monthly figure, not the annual one. If the same EUR 80,000 is paid as thirteen salaries of about EUR 6,150, each monthly payslip is lower and the thirteenth payment is taxed as a non-periodic payment. Over the year the result is close to the same.

Law and practice: Calculations by BCA EU on the 2026 parameters described above: contribution rates and ceiling from 1 June 2026 applied for the full year, scale from tax year 2025, CIS and CO2 credit from 2026. Payroll withholding uses monthly tables and can differ from the final tax assessment by a few hundred euros.

The impatriate regime, the thirteenth month and benefits in kind

The impatriate regime. Since 1 January 2025, employees recruited or seconded from abroad can have 50% of their gross annual salary exempt from income tax, up to EUR 400,000 of exempt pay a year. The regime runs until the end of the eighth tax year after the year they started work in Luxembourg. It replaced the older regime that exempted specific relocation costs and allowances.

• Salary. At least EUR 75,000 gross a year.
• Recruited from abroad. Not resident or taxable in Luxembourg in the previous five years, and not living within 150 km of the Luxembourg border in that period. Most cross-border workers from Thionville, Arlon or Trier are therefore excluded.
• The job. A new position, or one that replaces an existing impatriate, with at least 75% of working time spent on it.
• The employer. Impatriates must not exceed 30% of the workforce, except in companies less than ten years old. The employer files a list of impatriate employees with the tax authorities by 31 January each year.
• Social security. Contributions are due on the full salary, but only the part relating to the taxable half is deductible.

Thirteenth month and bonuses. Many Luxembourg contracts pay a thirteenth month, and collective agreements in banking and other sectors often require it. Bonuses and the thirteenth month are taxed with a special table for non-periodic income, which annualises the payment so that it is taxed at roughly the employee's marginal rate. Social security is due on them up to the annual ceiling, without the 0.25% cash sickness contribution.

Benefits in kind. A company car is taxed as a monthly percentage of its catalogue price that depends on its emissions, with the lowest rate for zero-emission cars. A rent-free flat, a low-interest loan and private use of a company phone are also taxable. Meal vouchers within the legal limits, a young employee bonus for workers under 30 and some profit-sharing bonuses are partly or fully exempt, which is why many employers package part of the pay that way.

Law and practice: LIR Article 115, No. 13b (impatriate regime, as reformed from 1 January 2025); ACD circulars on the impatriate regime and on benefits in kind; Grand-Ducal Regulation on withholding tax on non-periodic remuneration.

What the employer pays on top, and cross-border workers

Luxembourg employers pay social security on top of the gross salary but no separate payroll tax. The employer share is lower than in Belgium, France or Germany, which is one reason total labour costs in Luxembourg look moderate next to its high gross wages.

For a salary of EUR 80,000, the employer pays about EUR 10,060 on top, for a total cost of about EUR 90,000. At EUR 150,000 the total is about EUR 168,900. Above the ceiling the employer pays nothing more. Pension supplements, meal vouchers, a company car and the thirteenth month add to the real cost and should be in any budget.

Cross-border workers. A large part of the Luxembourg workforce lives in France, Belgium or Germany. They pay Luxembourg social security, are taxed in Luxembourg on the days they work there and, by default, are in class 1 unless they ask to be treated as residents. A non-resident can ask for that treatment if at least 90% of household income is taxable in Luxembourg; Belgian residents qualify from 50% of household professional income. Working from home is tolerated for 34 days a year for tax and up to 49% of working time for social security, under conditions explained in our guide to cross-border workers and telework.

Law and practice: Social Security Code; IGSS and CCSS social parameters for 2026; LIR Article 157ter and Article 24(4a) of the Belgium–Luxembourg tax treaty on the assimilation of non-residents.

Calculate your Luxembourg net salary

Simplified 2026 estimate for a resident employee with twelve salaries: standard allowances, the CIS, the CO2 credit and, for class 1a, the single-parent credit are included. Class 2 assumes one salary in the household. Real payroll uses monthly tables and your tax card, so expect small differences.
