I am a self employed tutor/ private english teacher what proofs do I need when I file my taxes, and do I need to prepay or can I just get it deducted out of my return?

Get what deducted from your refund?  If you are self employed and haven't been paying in the quarterly estimated payments then you will probably have a tax due on your 1040 tax return (not a refund).

For SE self employment tax - if you have a net profit (after expenses) of $400 or more you will pay 15.3% 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 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.)

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.

The 1040ES quarterly estimates for 2017 are due April 18, June 15, Sept 15 and Jan 16, 2018.  Your state will also have their own estimate forms. You mail in the estimates with a check or you can do it electronically at the IRS and maybe your state.

First of all,  If you buy the Desktop CD or Download Software any version will handle it but you will get more help in Home & Business.  For the Online versions you have to use the new Self Employed version (formerly called Home & Business).

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 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.

There is also QuickBooks Self Employment bundle you can check out which includes one Turbo Tax Home & Business return....

You need to keep good records and report all your income.  I wouldn't expect anyone to give you a 1099Misc for paying  you but they might if they pay you $600 or more for the year.
