How To Report Earnings

You must complete the following federal tax forms by April 15 following any year in which you have net earnings of $400 or more:

Form 1040 (U.S. Individual Income Tax Return);

Schedule C (Profit or loss from Business) or Schedule F (Profit or Loss from Farming as appropriate; and

Schedule SE (Self-Employment Tax).

These forms can be obtained from IRS and most banks and post offices.
Send the tax return and schedules along with your self-employment tax to IRS.

Even if you don't owe any income tax, you must complete Form 1040 and Schedule SE to pay self-employment Social Security tax. This is true even if you already get Social Security benefits.
