I work part time as a side job and receive a 1099 for commission only. What kind of business entity can I set up to write off a home office and car expenses

[Hal_Al · Accepted solution]

You don't "set up an entity". You simply file schedule C as part of (attachment to) your tax return. Your income and expenses go on Schedule C and your net profit ends up on line 12 of form 1040.  The home office deduction is calculated on form 8829. TurboTax (Self Employed version) can handle all that.

Schedule C is for self employed, sole proprietors.

This answer is correct.

how do i show 100% expenses on a 50% rental

 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.

For the future, There is also QuickBooks Self Employment bundle you can check out which includes one Turbo Tax Online Self Employed  return....

You need to report all your income even if you don't get a 1099Misc. You use your own records.  You are considered self employed and have to fill out a schedule C for business income.   You use your own name, address and ssn or business name and EIN if you have one.   You should say you use the Cash Accounting Method and all income is At Risk.   

After it asks if you received any 1099Misc it will ask if you had any income not reported on a 1099Misc. You should be keeping your own records.  Just go through the interview and answer the questions.   Then you will enter your expenses.

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.
