One of the lesser known trusts that people might be able to use to maximize their federal estate tax exemptions is called an AB trust. It is created by married couples, so it would be useful to many readers.
Normally, when one spouse dies passing on his/her assets in a last will and testament, the estate will be taxed heavily before the beneficiaries receive it. However, to avoid this steep estate tax, spouses can set up an AB trust, where each spouse leaves their property to an irrevocable trust.
That's the short version. Now the long.
