What is the maximum face value of Lunch vouchers?

The maximum amount deductible is €10.80. This amount was set by the Grand Ducal Regulation of 23 December 2016. This follows the limit of 1989 (LFr270), increased in 1996 (LFr330) and rounded up in 2002 (€8.18 => €8.40). Pluxee can print Lunch vouchers with higher values, but in such case the difference is taxable as salary!
