I live in Germany and I use public transport to go to work. I have a yearly public transport ticket which costs 1000€. The transport association offers me the choice of paying 1000€ in one transfer or via direct debit in 12 monthly installments of 1000€/12.
I understand the benefit of paying the ticket in monthly installments but I cannot figure out what the benefit would be if I paid the entire fee at once. I suspect that there might be tax implications since I believe that I can recover travel expenses from taxed income. Would paying one way or the other make a difference?
