My husband travels a lot for his job, and always claims business travel expenses on his taxes. There is usually a separate place to record these expenses.
I don't recall ever using the miscellaneous expenses section when I am doing our taxes.
The amount that you are able to deduct sounds like such a small percentage that I wonder how many people take advantage of it?
Even though the travel expenses my husband deducts are allowed, this is still an area that can throw up a red flag to the IRS.
I imagine any miscellaneous expenses would be watched very closely as well.
