Estate planning laws are changing in meaningful ways for 2026 – and while some of these updates create new opportunities, they also introduce uncertainty for Illinois families who want to protect what they’ve built.
Between proposed changes to the Illinois estate tax exemption and a significant federal estate tax update, 2026 is shaping up to be a pivotal year for estate planning.

However, the new law does not remove the need for careful estate planning, it just changes the rules.
Starting January 1, 2026, the federal estate and gift tax exemption will increase to a baseline of $15 million per person, indexed for inflation.
Even more importantly:
For years, estate planning at the federal level has been shaped by “use it or lose it” uncertainty. Permanency changes the conversation:
That said, federal law does not override Illinois estate taxes, which is why state-level planning remains critical.
