If the company reported your income on a Form W2, then you are considered as an employee and not an independent contractor. You will not be able to claim your work expenses. Even if you consider yourself as self employed the IRS will not.
You could complete a Form SS-8 to have the IRS determine if you are an employee or an independent contractor. Once you complete the form, the iRS will request the company you work for to provide their version of the SS-8.
