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.

Here is some IRS reading material……

You pay Self Employment tax on $400 or more of net profit from self-employment in addition to any regular income tax.  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.  

PAYING ESTIMATES

You may need to send in quarterly estimated payments to cover any self employment tax and increase in income.

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).
