My situation: I've been working for only one employer but in two different places, also from two different places as I moved during the year. Furthermore, because I was not commuting every day I didn't buy any abo, just individual tickets.
The ZH online form asks for the cost of a subscription. Does it have to be a real subscription, backed by receipt, or just a cost of such subscription? Can I just lookup the cost of local transportation subscription in both places and put there the sum?
In VD, it was much clearer. The form accepted any number of lines: from, to, km. The tax office did the calculation how much the public transportation would cost on those routes.
