To report your self employment income you will fill out schedule C in your personal 1040 tax return and pay SE self employment Tax.

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.

PAYING ESTIMATES
The first year you don't need to pay estimates as long as you pay in (by withholding) as much as your tax was last year.  But if you will have a big income you should send in estimates so you don't owe too much next April on your tax return.

You must make quarterly estimated tax payments for the current tax year if both of the following apply:
- 1. You expect to owe at least $1,000 in tax for the current tax year, after subtracting your withholding and credits.
 
- 2. You expect your withholding and credits to be less than the smaller of:
    90% of the tax to be shown on your current year’s tax return, or
  100% of the tax shown on your prior year’s tax return. (Your prior year tax return must cover all 12 months.)

To prepare estimates for next year you start with your current return, but be careful not to change anything.  For Online versions, if you can't get back into your return, Try this, you can sign back onto your account, click the Visit My Tax Timeline and then under SOME THINGS YOU CAN DO, click on Add a State.  This should get you back into your return.

You can just type W4 in the search box at the top of your return , click on Find. Then Click on Jump To and it will take you to the estimated tax payments section. Say no to changing your W-4 and the next screen will start the estimated taxes section.
