Hi,
here in Germany I claim:
-my Uniform
-cleaning of my uniform
-suitcase
-flightkit
-tips
-1 p. of shoes (lifespan is much shorter )(f.colleages also thights)
-computer
-telephone
-costs for 2nd creditcard
-transporation to AP
-applikationcosts
-costs made during training (this incl. time without income)
-ensurence
-languge course
Off course I have German courtrulings for these claims, but you can try where ever you are. Important is that you can make them plousable and convinced when you talk with these tax-guys. Good-luck
