As a general rule, crop insurance indemnities are included in your income for the year you receive the indemnities. However, you can choose to defer reporting your indemnities if you can show that you normally defer your crop revenue into the next calendar year. That means you'll need to be prepared to show that you typically sell more than half of your bushels for that particular crop in the year after you raise the crop.
If you are eligible for and choose to defer a crop insurance indemnity, you have to defer the entire payment. You can't defer only half of an insurance payment on your corn, for instance. Indemnities from county-basis group insurance cannot be deferred because there is no relationship between that indemnity and a producer's yield.
Indemnities cannot be reported as income before you receive them. An indemnity received in 2013 for 2012 crop is reported as income in 2013 - regardless of when you normally sell that crop. It's important to consult your ag risk advisor and your tax advisor with any questions about how you'll manage revenue from crop insurance indemnity payments.
