Your self-employment income is reported on Form 1040, Schedule C (PDF), Profit or Loss from Business, or on Form 1040, Schedule C-EZ (PDF), Net Profit from Business.

Your Medicare and social security taxes are reported on Form 1040, Schedule SE (PDF), Self-Employment Tax.

As a self-employed person, you pay your Medicare and social security taxes the same way you pay your income taxes. If you expect to owe less than $1,000 in total taxes, you can pay them when you file your income tax return. If you expect to owe $1,000 or more in total taxes, you will need to make estimated tax payments. These payments are made quarterly using Form 1040ES (PDF), Estimated Tax for Individuals. You will need to figure these taxes at the beginning of the year. To learn about figuring and making estimated tax payments, please refer to Publication 505, Tax Withholding and Estimated Tax.
