Tax Trails - Self-Employment Income
If you're engaged in farming and are not an employee, you're usually considered self-employed and may owe self-employment tax on your net earnings.
You report your farm income and expenses on Schedule F (Form 1040), Profit or Loss From Farming. This includes income and expenses you have from a farm partnership shown on Schedule K-1 (Form 1065), Partner's Share of Income, Deductions, Credits, etc.
Income from farming that you report on Schedule F (Form 1040) includes, but isn't limited to amounts you receive from cultivating the soil, raising or harvesting any agricultural commodities, or managing a farm for gain or profit either as owner or as tenant.
Figure your self-employment tax on Schedule SE (Form 1040), Self-Employment Tax.
If you earn or receive income during the year that's not subject to withholding or you don't have enough tax withheld, you may have to pay estimated tax. If you don't pay enough tax during the year through withholding or by making estimated tax payments, you may have to pay a penalty. See Tax Topic 306 – Penalty for Underpayment of Estimated Tax.
