Luxtoday launches an updated Luxembourg tax calculator with 2028 reform simulation

Luxtoday has released a major update to its Luxembourg Income Tax & Net Salary Calculator, allowing users not only to calculate their current net salary, but also to estimate how the proposed 2028 tax reform may affect their income.The updated calculator now supports:

Current 2026 tax classes (Class 1, 1a and 2);
The proposed new Tax Class U;
The transitional Tax Class T for married couples;
Salary and tax comparisons between different tax regimes;
Net salary calculations after income tax, social contributions and solidarity surcharge.

One of the most important new features is the ability to compare the current system with the proposed 2028 reform. Users can see how much tax they may pay:

as a single employee;
as a married couple;
under Tax Class T;
after switching to Tax Class U;
before and after the reform takes effect.

The reform is expected to introduce a new principle of individual taxation through Tax Class U, while existing married couples may remain under a transitional Tax Class T regime for up to 25 years.This makes the calculator particularly useful for married couples, people planning to get married, and anyone who wants to understand how future tax changes could impact their household budget.The calculator also includes explanations of Luxembourg tax classes, social contributions, solidarity surcharge and tax residency rules, making it a practical tool for both residents and newcomers.👉 Try the updated calculator here: https://luxtoday.lu/en/tax-calculator
