Here in Indiana there is no size requirement either. Anyone qualifying for a landowner tag can tag deer, up to the legal bag limit,without a license. The reg reads:
Landowners or lessees of farmland who farm that land and are residents of Indiana, their spouses and children living with them,
while hunting, fishing or trapping on the land they own or lease. This exemption does not apply to land owned by a business, corporation
or partnership unless the shareholders, partners, members or owners are comprised solely of the members of an immediate family
and farm that land. Farmland means agricultural land that is devoted or best adaptable for the production of crops, fruits, timber or
the raising of livestock, or is assessed as agricultural land for property tax purposes
In our home county of Fulton, I can kill 1 buck and up to 8 doe without a license on the home place. So can my wife or my son if he happens to be home on leave at that time. As long as the land is zoned agricultural on my tax statement, there is no questions asked. I always buy a license for buck as I have several other places to hunt that are not on my own property.
