Estate Planning in Illinois — Tax-Smart Wealth Protection

Yes — Illinois has a state-level estate tax ($4M Exemption) IN ADDITION to the federal estate tax. This means Illinois residents can face combined effective rates exceeding 50% on estates above the threshold. Proper planning with irrevocable trusts, SLATs, and gifting strategies can eliminate or significantly reduce both state and federal exposure.

Illinois estate planning costs range from $2,000–$25,000+ depending on complexity. A basic revocable living trust package runs $3,500–$7,000. Complex planning with irrevocable trusts, FLPs, and business succession for high-net-worth families typically costs $10,000–$25,000. The ROI is substantial — a $15,000 estate plan that saves $1.5M in federal estate taxes delivers a 100:1 return.

For most Illinois residents, a revocable living trust is the foundation — it avoids probate, maintains privacy, and provides incapacity protection. For estates over $7M, add irrevocable trusts (SLATs, ILITs, dynasty trusts) to remove assets from your taxable estate. For business owners, a combination of buy-sell agreements, FLPs, and GRATs freezes business value.

The federal estate tax exemption drops from $13.61M to approximately $7M per individual on January 1, 2026. For Illinois families, this means a married couple with a $15M estate currently owes $0 in estate tax, but after 2026 could owe $400,000+. A single individual with a $10M estate goes from $0 to potentially $1.2M in estate tax. The window to implement gifting strategies, GRATs, and irrevocable trusts is closing.

A Spousal Lifetime Access Trust (SLAT) allows one spouse to gift assets into an irrevocable trust for the benefit of the other spouse, removing those assets from both estates while maintaining indirect access. For Illinois married couples with estates between $7M–$25M, a SLAT is one of the most powerful tools available before the 2026 sunset. It uses your current high exemption before it drops.

Illinois business owners should implement: (1) A buy-sell agreement funded by life insurance to provide liquidity. (2) A Family Limited Partnership (FLP) to transfer business interests at discounted values. (3) A GRAT to freeze business value and transfer future appreciation tax-free. (4) Proper succession planning documentation. Without these, heirs may be forced to sell the business to pay estate taxes.

Without an estate plan, Illinois intestacy laws determine who inherits your assets — which may not align with your wishes. Your estate will go through probate (public, expensive, and slow). The court will appoint a guardian for minor children. Your family will have no tax planning in place, potentially paying hundreds of thousands in avoidable estate taxes. Business assets may need to be liquidated.

Step-up in basis means that when you die, your heirs receive your assets at their current fair market value — not your original purchase price. For Illinois families with appreciated real estate or investments, this eliminates capital gains tax on decades of appreciation. A home bought for $200K now worth $1.5M? Your heirs inherit at $1.5M basis — zero capital gains tax if they sell. This is a massive benefit that proper estate planning preserves.

If your estate exceeds $7M, yes — the window to use your current high exemption ($13.61M) closes on January 1, 2026. Strategies include: gifting to irrevocable trusts (SLATs, dynasty trusts), creating GRATs to freeze asset values, funding ILITs with life insurance, and establishing FLPs for business interests. Once the exemption drops, these opportunities are gone permanently. Illinois residents should act now.
