There are provisions for that too. There are special exemptions for farms. Part of the reason the numbers are so low is that there are exemptions for farmers and small businesses written into the estate tax code that allow most farmers — with a bit of estate planning — to avoid the estate tax altogether. For example, if the heirs agree to farm the land for another 10 years, they can get up to a $1 million exemption by valuing land at its farm use value rather than development value. An additional $500,000 exemption is possible if one agrees to a perpetual conservation easement restricting the use of the land. It is also possible to reduce the value of an estate by giving portions of the estate to heirs as a gift over a number of years. For a full description of exemptions available to farmers, see this Congressional Research Service report, starting on page 2. The law also includes a provision that allows those who inherit a farm, and are having trouble paying the estate tax, to spread those payments over 14 years at a low interest rate.
