Deductions & credits

Unfortunately, you cannot deduct your home office expenses.   To take a deduction for your home office, you must regularly use a portion of your home exclusively for conducting business.

Also, it must be your principal place of business. If you are an employee looking to take the home office deduction, you must also be using your home for the convenience of your employer, rather than for your own convenience
