I've been through the tax deduction threads - which are helpful - but I couldn't find an answer to that appeared to cover this question. I am an academic living in Vaud, I will be making under 120K so taxed at source on a B permit. I travel to many conferences (looks like the US at least three times this year and Shanghai plus European cities) - all is work; none are cheap. I also hold a visitorship at UCLA, where I will spend a month a year. Are these fares, hotels, car rental and conference registrations deductable? They are obviously connected to my work and reputation, but I don't earn money while doing them. It would be good to know before I start booking them (I have no aversion to paying an accountant or doing a tax return).
Many thanks in advance, all I want to know is whether I should be able to deduct them or not as it might make a difference to the amount of palm pressing I can get done
