The Training benefit has no tax exempt limit.
Although there is no exempt limit, there is a limit on the use of remuneration in kind. If at any time the limit of 30% of your remuneration is exceeded, all transactions would be rejected.
🎓 For example: if my salary is €24,000 gross per year, I cannot spend more than €7,200 of my salary.
In addition, the monetary remuneration must never be less than the Minimum Interprofessional Wage (SMI), which is set at €1,000/month or €14,000/year.
🎓For example: if my salary is €18,000 gross per year, I will not be able to spend 30% (€5,400) because it would fall below the €14,000/year (€18,000 - €5,400 = €12,600).
