With the current Gift tax exemption at 5 million dollars + 13,000 per person per year, many people are not concerned about making gifts or the taxes. It is important to remember that unless a gift tax return is filed with annual gifts to an individual exceed $13,000 there could be penalties and interest for the unreported gifts. Talk to your CPA about filing a gift tax return if you are giving an individual more than the exempt $13,000 per year.
In addition, gifts keep the current basis so to the extent that you give an appreciated asset, the recipient will have to pay the capital gains based on your cost. If they inherit the asset, there the beneficiary receives the asset as the cost basis as of your date of death. This can have significant advantages to highly appreciated assets.
Lets say you have Apple stock you purchased at $14 a share 12 years ago. It has split 3 times since then so your cost is less than $5 a share. With a value today of $350 / share and a value of $500 when you die.
