“The only thing I would ask for clarification on (and perhaps the main reason I posted this question) is the term "tax home". I see this mentioned in the IRS code and to me the way it is stated, leads me to believe that my "tax home" is city B not A - where I currently live and work. Am I reading this correct?”-------->I guess it depends on the situation; your tax home is the general area in which your biz/work is located, regardless of where you maintain yourfamily home.As long as youhave more than one place of work, you need to use some factors to determine your tax home;the total time spent at each place of biz;the degree of biz activity in each area;the relative income earned at each place of biz. As you do business in more than one location, you need to declare one of them to be your “tax home” in order to deduct travel between A and B. When you travel away from your tax home and stay overnight, you can take the deduction for all your expenses. If you don’t stay overnight, only your travel costs can be deducted, but not your meals.If you combine business and pleasure in the same trip, you can only deduct the portion of your travel expenses attributable to business. ALSO, once you determine your tax home, then,if you are on a temporary assignment to an area away from your tax home, you can deduct the living expenses that you have during the temporary assignment. In general, temporary assignment is one that is expected to last NO MORE THAN one year, so, you must determine whether your assignment is temporary or indefinite when you start work.If it is realistically expected to exceeds one year, it is considered indefinite and you can’t deduct your living expenses while there. If yu expect it to last more than one year, and it is in fact doesn’t last more than on e year, you can’t deduct the living expenses.
