It's my understanding that meals are 50% deductible on a business trip. Given that, I have two questions:
1) Does this include groceries if you choose to eat in your hotel room?
2) When does a business trip become "living out of town"? For example, I spent a year in Chicago on a work contract and maintained my residence in Dallas. If I flew to Chicago on a Sunday and came back on Friday, then I think it's clear that meals would be 50% deductible. What if I stayed two weeks, or four weeks, or even eight weeks, between trips home? Does that make it less of a "business trip"? (The purpose for being there is to earn money working as software contractor.) What if I had an apartment there? Does the length of stay, or renting an apartment disqualify it from a business trip?
