Not entirely accurate.
It depends on cantons again, you will find this with everything in Switzerland. Ask 10 people, get 5 different responses.
I live in Aargau and was able to submit a tax return even though I pay through the PAYE equivalent. I was able to claim it back, but it's not much. First thoughts are that you have paid much too much, but it's not. The other 11 months you have effectively been underpaying tax as the 10% you have been paying should have been slightly more (given that your salary was higher in November).
Give a tax adviser a ring if I were you, I would recommend this person, she's mustard!!
