You need an estate plan whether or not the estate tax (and GST) applies to you. Tax avoidance (or more accurately, minimizing the estate tax) is not the only reason to establish your estate plan.
Do Not Let the State Distribute Your Estate
The primary focus of most estate plans is to determine how to distribute your assets. If you do not have an estate plan, the state imposes its plan on you, and the state's succession statutes will determine how your assets are distributed.

Rule From the Grave
Perhaps one of the most powerful tools an estate plan can provide is the peace of mind that your hopes and goals for your children will be relevant after you are gone. By transferring your assets through a trust, rather than outright, you can provide substantial limitations on the distributions from the trust.
Do Not Delay Have Your Say
If you have children who are minors, you need to establish who will care for them if you pass away. This may especially important if your child's other parent is remarried, absent, or otherwise ill-prepared to handle the responsibility of raising your children.
Plot Your Own Fate and Avoid Probate
Probate – the administration and distribution of your estate through the probate courts- can be an expensive, time-consuming process. However, with the proper planning, it can be easily avoided. Estate planning is especially important to avoid probate when you own real estate in more than one state.
