Enter as direct or indirect expenses only expenses for the business use of your home (that is, expenses allowable only because your home is used for business). If you did not operate a business for the entire year, you can deduct only the expenses paid or incurred for the portion of the year you used your home for business. Other expenses not allocable to the business use of your home, such as salaries, supplies, and advertising, are deductible elsewhere on Schedule C and should not be entered on Form 8829.
Direct expenses benefit only the business part of your home. They include painting or repairs made to the specific area or rooms used for business. Enter 100% of your direct expenses on the appropriate line in column (a).
