With all the talk and it is currently only talk, there is a question of what will happen with the gift tax?
Most expect it to stick around in some form or another.
It is considered to act as a backstop to help prevent income shifting from donors in high tax brackets to donees in lower tax brackets.
If Congress does end up getting rid of the estate tax, look for them to impose a lifetime gift tax exemption, maybe in the range of $1 million or higher, and preserve the annual gift tax exclusion, which is currently $14,000.
