Qualification for Form 4835
The IRS considers "material participation" to be the determining factor as to which farm income tax form you should file. If you're a traditional farmer who raises crops or livestock, you're considered a self-employed business person and you would file using Schedule F, Profit or Loss From Farming.
However, if you merely rent out your land to farmers and do not materially participate in the labor or management of the farming process yourself, you are considered a landowner, not a farmer, according to the IRS. Form 4835 is the way for non-participating farmland owners to report their farm income and expenses.
based on the info that was provided Schedule F is the appropriate form.
the fact that because she may never collect social security because of her pension plan, not sure this is true - she should contact the Social Security Adm to verify her status, has no bearing on the proper form to use. Improperly avoiding paying self-employment taxes when owed can result in substantial penalties.
