If you receive a 1099 for services performed then you are considered an independent contractor and required to file form Schedule C as a sole proprietor. As a sole proprietor in addition to income tax you will also have to pay self-employment SE (social security) tax. The SE tax on $60,000 will be approximately $8,478 (you do receive an adjustment for 50% of this on your 1040). Your income tax if you file as a single individual and do not itemize will be approximately $8,177. So your total federal income tax will be approximately $16,655 ($8,478 + $8,177).
That means that 50% of your SE tax ($8,478 x .50 = $4,239) is entered as an adjustment to income on line 27 of Form 1040 which in turn reduces your adjusted gross income of $60,000 to $55,761 resulting in a reduction of income tax.
