I understand that any expenses must be wholly for business purposes, so that means normal eating doesn't count, it has to be outside the usual pattern of business.
However there seem to be a lot of subtle cases where it's not clear:
- I do a 6 week contract in the client's office in another part of the city. I take the train and eat lunch out every day. Are travel and food both valid? Does it change anything if I do some of this work from home?
- I decide to work from somewhere else like a coffee shop. I don't think I can claim for food, but can I claim for bus/train fare there?
- I take a client out for coffee or a meal to discuss a new project.
- I go overseas for a project staying Monday to Friday - can I claim for all the travel and food expenses incurred while on the trip? Does it change anything if part of the trip is for leisure?
