Well, I get rooted over at tax time.
This year, I had to buy a phone and a laptop for work, totalling about $2500. The laptop is salary sacrificed, and therefore invoiced to the company, so I can't use that for tax, and the phone is part of a plan, but I paid $0 up front but pay the phone off over the year. The invoice I got for that is for $0, so I can't use that for tax...
Bastards.
