For tax years 2024–2025, the federal estate tax exemption is $13,610,000 per individual ($27,220,000 for a married couple utilizing spousal portability via Form 706). Estate assets above this threshold are taxed at a flat top federal rate of 40%.
Twelve states and the District of Columbia impose state estate taxes (MA, NY, WA, OR, IL, MD, CT, VT, RI, ME, MN, HI), and six states impose inheritance taxes. Notably, Massachusetts ($2M) and Oregon ($1M) have much lower exemption thresholds than the federal government.
New York has a punitive 'cliff' rule: if your taxable estate exceeds the state exemption threshold ($6.94M) by more than 5%, you lose the entire exemption retroactively. The estate is taxed from dollar one, potentially generating hundreds of thousands in taxes on just an extra dollar of wealth.
