To enter cash income without a 1099Misc into the Online Self Employed version, if you see a Business tab at the top, after Personal Info, follow the instructions to enter the cash as General Income. If you do not see a Business tab, choose the second topic of Additional Income underneath the 1099-Misc income topic.
Is this the first year you are self employed?
You need to report all your income even if you don't get a 1099Misc. You use your own records. You are considered self employed and have to fill out a schedule C for business income. You use your own name and ssn or business name and EIN if you have one. You should say you use the Cash Accounting Method and all income is At Risk.
Self Employment tax (Scheduled SE) is automatically generated if a person has $400 or more of net profit from self-employment. You pay 15.3% SE tax on 92.35% of your Net Profit greater than $400. The 15.3% self employed SE Tax is to pay both the employer part and employee part of Social Security and Medicare. So you get social security credit for it when you retire. You do get to take off the 50% ER portion of the SE tax as an adjustment on line 27 of the 1040. The SE tax is already included in your tax due or reduced your refund. It is on the 1040 line 57. The SE tax is in addition to your regular income tax on the net profit.
