When you have 1099-MISC income, it is considered self-employment income whether or not you own a separate business.
Therefore, you would be able to claim any ordinary and
necessary business expense that relate to your self-employment income.
This can include
such things as any unreimbursed business miles driven to a client or work
location, home office expense if you uses a part of your home exclusively for
your job and supplies or equipment used in your work to name just a few.
