Last year I applied for the expat deduction (couple of months of 2008), applied in late March 09, received money in May or June. This was done by the Tax Consultant (paid by employer for the first year).
This year received the offer from the consultant (Chf 800,-

), and decided to file myself using Vaud tax and Google translator (I speak zero French). Filed at their office in March, will see how fast they will process.
