You can deduct those items TheDiva320 said but you must keep track of what is business and what is personal. For example if you have a home office, do you use it exclusively for business? If not the IRS may disallow it, same goes for all expenses (computer, printer, etc....), you can only deduct the % of the gas water, utilities that relate to the use of your home office, so if it's 10% of the total square footage and used exclusively for business then and only then can you deduct 10% of your utilities (including internet). Groceries are NOT allowed, as you would still have to pay for your own food if you were working at an office outside your house.
