Can I claim a tax deduction for working from home as an employee? I work there 90% of the time
The general rule is: Generally, in order to claim a business deduction for your home, you must use part of your home exclusively and regularly: Exclusively seems to be the toughest standard and I do not know exactly how strict the IRS's interpretation is. Working in your living room where you regularly watch TV and have people over on the weekends would seem to fail that test. A separate room with your computer in it would pass it. If it was your only computer and you regularly played online games with it, that would seem to be a grey area.  The IRA booklet covering this area is here http://www.irs.gov/pub/irs-pdf/p587.pdf I know people that have rented rooms in other places or made use of rental offices for this purpose.
