[After this post was published, Congress passed the Tax Cuts and Jobs Act, which changed estate tax exemptions starting in 2018. Read this article for more information.]
The IRS recently (officially) announced increases in the estate and gift tax exemption for 2018. The combined exemption will be $5.6 million per individual, up from $5.49 million in 2017. In other words, if you die in 2018, you can leave $5.6 million (or $11.2 million for married couples*) to heirs without paying a federal estate or gift tax.**
The annual gift exclusion amount also has increased to $15,000 in 2018—up from $14,000 in 2017. This means you can now give away $15,000 (and a husband and wife can each gift $15,000) to as many individuals as you want each year without paying any gift tax. For example, starting in 2018, a couple could make $15,000 gifts to each of their four grandchildren, for a total of $120,000. Gifts beyond the annual exclusion amount count towards (i.e., reduce) the $5.6 million combined estate/gift tax exemption.
