I do housecleaning on the side. I have zero overhead expenses. As my clients provide all products. How much can I make per job without reporting?

You must report every single dollar of self employment income ...

If you are new to being self employed, are not incorporated or in a partnership  and  are acting as your own bookkeeper and tax preparer you need to get educated ....  

If you have net self employment income of $400 or more you have to file a schedule C in your personal 1040 return for self employment business income. You may get a 1099-Misc for some of your income but you need to report all your income.  So you need to keep your own good records. Here is some reading material……

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.

Sorry you have to report ALL  your income no matter  how small.  Even $1 of bank interest.   

That is self employment income.  Even if you don't owe any income tax on your income you will still owe 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.

It is not "per job."  If you earn at least $400 total as an independent contractor the tax law is that you have to report the income as self-employment income.

What if I didn’t get a 1099-MISC, but made money from self-employment?

To enter your self-employment income not reported on a 1099-MISC:

1. When in your account, select the Take Me to My Return button on the main screen.
2. Type “Schedule C” in the Search box
3. Select the “Jump to” link.
4. Answer the general questions about your business (or select Edit at the work summary screen).
5. At the Let’s get income for… screen, select Additional Income.

If you did make $600 or more, contact the company or individual you worked for.
