Assuming you have a simple business, such as rental income, Uber driver income, and etc.
1. File F1040 and all others that you usually should file, plus
2. File Schedule C - Profit or Loss From Business (assuming you have profits)
3. File Schedule SE - Self-Employment Tax (In general, if you owe $1000 or more tax on F1040, be sure to pay estimated tax each quoter to avoid penality. You can do this online.)
4. File Schedule 1-5, whichever are required. Then refine Form 1040.
* The amount on 3 (Self-Employment Tax) will be counted towards your social security benifit/Medicare. I would suggest you use a tax software to make life easier.
借贵论坛宝地问个个人问题，请教各位，个人自雇如何缴social security tax， 填哪一个IRS 表格，多长时间报一次。若按最低工资标准缴，2019年最少应缴多少可获得4 working credits? 网上信息很乱，查半天也不知该怎么缴，烦请各位详述，多谢。

如果還不明白，請諮詢會計師.
make deposit every month. file form 941 every quoter.

谢谢回复，请问个人没注册公司，那么FORM941 里的EIN 等信息就填个人信息吗？再次感谢！
