Work from home is an employee business expense.
To deduct employee business expenses, you must have enough itemized deductions (ie. Medical, mortgage interest, property taxes, charitable giving, ect) to exceed your Standard Deduction. If you itemize, your deduction is limited to the extent that it exceeds 2% of your Adjusted Gross Income.
So, you may not gain a tax benefit from the deduction.
