scrounge wroteGoing from Z to H should be just fine as long as it's truly a temporary job location, not a 2nd job location, and you are employed with a regular job location outside the home. Home-based workers and retirees are out of luck, but for most of us Z to H is ok. I'm sure you've seen this chart before, right out of Pub 463.
Yeah, but I'm keep it conservative to people when I give advice. Nothing worse than having someone come after you because "You said it was fine!". Now, if you listen to some guy on the internet. 🙂
Also, that workstation has to be outside "the metropolitan area". How many of us really leave the "metro area" for HS reffing? Don't get me wrong, I've gone 40-50 miles for some games, but the DC Metro area is almost from Winchester to Fredericksburg (60 mile radius). That being said, I highly doubt the IRS is going to check your log book.
