Illinois Estate Planning — What Retirees Need to Know in 2026
Illinois levies a state estate tax on estates above $4,000,000, which catches many middle-class retirees off guard. Probate costs 3–7% of your gross estate and takes 6–12 months on average — costs that can be avoided with the right documents in place. Illinois recognizes TOD deeds, giving residents cost-effective ways to transfer real property outside of probate. Medicaid estate recovery in Illinois is expanded — the state can recover from assets that passed outside of probate, including TOD deeds and some trust accounts. Advanced planning is essential.

Illinois Probate: What It Costs and How to Avoid It
Illinois uses its own probate code, which can make the process more structured and court-supervised than UPC states. Even so, probate still costs 3–7% of gross estate value and takes 6–12 months on average. Estates under $150,000 (effective 1/1/2026; vehicles excluded from cap) may qualify for a simplified affidavit process.
- Revocable Living Trust Assets properly funded into a trust pass outside probate and remain private. Typical cost range: $2500–$5000.
- TOD Instrument Expanded recovery state; TOD deed does not protect home from Medicaid estate recovery. Trust or Lady Bird Deed (where available) may offer better protection.
- Joint Ownership Planning Joint tenancy structures can avoid probate but may create tax or creditor exposure. Review before implementing.
- Small Estate Affidavit Available for estates under $150,000 (effective 1/1/2026; vehicles excluded from cap). Waiting period: 30 days.
