You figure self-employment tax (SE tax) yourself using Schedule SE (Form 1040). Social Security and Medicare taxes of most wage earners are figured by their employers. Also you can deduct the employer-equivalent portion of your SE tax in figuring your adjusted gross income.
Many sole proprietors can use their SSN and still file a Schedule C with their Form 1040. If you have employees or file excise or pension tax returns, you must apply for an EIN. If you are filling out a business form, use your EIN if you have one. Otherwise, use your SSN or ITIN, whichever applies to your situation.
