Is there gift tax in Maryland, D.C. or Virginia?

No, but there is gift tax at the federal level for gifts in excess of $ 11,580,000 per person or $23,160,000 per couple (in 2021). This does not include the annual gift tax exclusion amount which is  still at $15,000 per year per gift recipient. Gifting during life is an EXCELLENT way to reduce the state estate tax exposure of your probate (or trust) estate. Few people today need worry about federal estate taxes in the District, Maryland or Virginia because of this extremely high exemption at the federal level (which might change under a Biden administration). The District’s estate tax exemption has just been reduced to $5 million per person for 2021 and in the District, this estate tax exemption is NOT PORTABLE to a surviving spouse so you “use it or lose it”.
