Some general info on self employment...........
You will need to keep good records. You may get a 1099Misc at the end of the year if someone pays you more than $600 but you need to report all your income no matter how small. You might want to use Quicken or QuickBooks to keep track of your income and expenses.

When you are self employed you are in business for yourself and the person or company that pays you is your customer or client.
To report your self employment income you will fill out schedule C in your personal 1040 tax return and pay SE self employment Tax. You will need to use the Online Self Employed version or any Desktop program but the Desktop Home & Business version will have the most help.
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 Schedule 1 line 27. The SE tax is already included in your tax due or reduced your refund. It is on the Schedule 4 line 57. The SE tax is in addition to your regular income tax on the net profit.
