Hi all,
I think this is a fairly common topic, but I couldn't find very clear answer to this question. Today is 25th Jan. In order to qualify for 2015 tax deductions, can someone still make contribution to Pillar 3a (Canton Zurich)? I got some hints in some of this forum's threads that if you count vacation days for 2015 etc, you could still do it. But I might have misunderstood as nowhere did I find it mentioned explicitly. Is the deadline for 2015 already long gone with the end of that year?

Another question- can air fares to your home country qualify for tax returns? If I file tax returns this March, can I also do it for previous years 2014, 2013? I have not filed a tax return in Switzerland before, and I don't know what expenses qualify and what are the relevant time-frames?

Pillar 3a: no...it must be done before 31 Dec 2015.
