Self Employment tax (Scheduled SE) is generated if a person has $400 or more of net profit from self-employment on Schedule C. You pay 15.3% for 2017 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
For SE self employment tax - if you have a net profit (after expenses) of $400 or more you will pay 15.3% for 2017 SE Tax on 92.35% of your net profit in addition to your regular income tax on it. So if you have other income like W2 income your extra business income might put you into a higher tax bracket.
You must make quarterly estimated tax payments for the current tax year (or next 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 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.

@apapadopoulos 30% held back is a good number. Whether or not it will completely cover the anticipated tax liability will depend on a few other factors (especially your overall combined income). But as long as you and your wife are in the "12%" tax bracket, then your total tax on the income should be no more than 27% (and likely less than 25%, with other deductions that will be factored in). Since you live in Texas, and there are no state or local taxes to pay, you sound like you've held enough back. And this will be even more certain if you've held back the 30% from her gross income amount, because you will pay tax (including self-employment tax) on net income amounts.
Having said that, please review the information @CRitter3 provided, especially with regards to making estimated payments. Going forward, you'll want to do this in order to not face underwithholding penalties for not contributing enough tax throughout the year.
