To file your annual tax return, you will need to use Schedule C (PDF) or Schedule C-EZ (PDF) to report your income or loss from a business you operated or a profession you practiced as a sole proprietor. Schedule C Instructions (PDF) may be helpful in filling out this form.
Small businesses and statutory employees with expenses of $5,000 or less may be able to file Schedule C-EZ instead of Schedule C. To find out if you can use Schedule C-EZ, see the instructions in the Schedule C-EZ form.
In order to report your Social Security and Medicare taxes, you must file Schedule SE (Form 1040), Self-Employment Tax (PDF). Use the income or loss calculated on Schedule C or Schedule C-EZ to calculate the amount of Social Security and Medicare taxes you should have paid during the year.
