With the release of the Chained Consumer Price Index (C-CPI-U) for August 2023, it’s possible to calculate various inflation adjustments for 2024. The following are the significant federal estate planning numbers, with the numbers for 2023 shown in parentheses:

• The federal estate tax base applicable exclusion amount (and generation-skipping tax exemption) will be $13,610,000 (was $12,920,000 for 2023).
• The annual gift tax exclusion will be $18,000 (was $17,000).
