Hi and welcome to our site!
As a real estate broker - generally you are classified as a self-employed person.
You will report your income and may deduct qualified expenses.
- you may report all business income and expenses -on the schedule C -
The net income (after deductions) will be reported on the form 1040 line 12 -
If the business has net income over $400, it may be required to file Schedule SE, Self-Employment Tax
and net self-employment income is subject to 15.3% self-employment tax.Self-employment taxes from schedule SE will go to the form 1040 line 57 -
Also - you will deduct half of self-employment taxes on the line 27.
Generally - that all you needs tax purposes.
Please review all possible deductions - that might help to reduce income tax liability.
Generally your tax liability for 2015 is due by Apr 15, 2016, but if you will owe more than $1000 you might need to pay estimate taxes.
I will help you with estimations, but the first step is to list all your deductible expenses.
