The problem is said to have been caused by the German tax authorities taxing the hours worked in Germany, then adding the amount that was exempted from tax in Luxembourg for the same hours.
As a result, the different legislation means slightly different amounts can appear on the tax certificates issued by the employer for each country. If an employee works for a Luxembourg-based branch of a German company and works from home more than 34 days a year, their employer has to issue two tax certificates.
The issue does not apply to employees of a Luxembourg company.
Aleba advises all workers affected to file a complaint with the German tax authorities. The form can be found on the union’s website.
