A couple walks into our office, both successful professionals in their 60s. They’ve accumulated $7 million in assets through decades of hard work. They assume they’re fine because they heard the federal estate tax exemption is over $13 million.
“We don’t need estate tax planning, right? Our estate is way under the federal limit.”
Then I explain Illinois estate tax planning for couples. Unlike federal law, Illinois doesn’t let spouses share exemptions. Without proper planning, their estate could owe over $500,000 in Illinois estate taxes—money that should go to their children.
Their faces change. This conversation happens weekly.
Why Illinois Estate Tax Planning for Couples Is Different
Illinois estate tax planning for couples requires strategies that many attorneys in other states never need to discuss. The reason comes down to one critical difference: portability.
- Federal law allows portability. When one spouse dies, the surviving spouse can use any unused portion of the deceased spouse’s exemption. A couple effectively gets $27.98 million in federal protection for 2025 (doubling to $30 million in 2026).
- Illinois does not allow portability. Each spouse has only their individual $4 million exemption. Period. You can’t transfer the unused exemption to your surviving spouse.
This creates a significant problem for married couples’ estate planningin Illinois. Without strategic planning, couples can only protect $4 million—not $8 million—from the Illinois estate tax.
How Illinois Estate Tax Can Impact Couples Without Planning
Let’s look at a common scenario for an Evanston couple with substantial assets and no Illinois estate tax planning.
The situation:
- Combined estate of about $7 million
- A primary residence
- Retirement and investment accounts
- Life insurance
What happens without planning
The husband dies first and leaves everything to his wife, which is a very common approach. Because of the unlimited marital deduction, no Illinois estate tax is due at the first death. All assets pass to the surviving spouse.
The wife now owns the entire estate, which is well above Illinois’s $4 million estate tax exemption. Because her estate exceeds the exemption by roughly $3 million, the family could face over $400,000 in Illinois estate tax at her death, depending on valuations and other factors at the time.
That is money that might otherwise have gone to children or other beneficiaries, lost simply because Illinois does not allow spouses to “port” unused estate tax exemptions, and no planning was done.
The Solution: Credit Shelter Trusts for Illinois Couples
Illinois estate tax planning for couples typically involves credit shelter trusts (also called bypass trusts or family trusts). These trusts help married couples in Illinois actually use both $4 million exemptions.
How credit shelter trusts work:
When the first spouse dies, up to $4 million goes into a trust instead of directly to the surviving spouse. This amount uses the deceased spouse’s exemption.
The surviving spouse can receive income from the trust and sometimes principal for health, education, maintenance, and support. But the trust assets aren’t included in the surviving spouse’s taxable estate.
The surviving spouse’s own assets (up to $4 million) use their personal exemption.
Result: The couple protects up to $8 million from the Illinois estate tax instead of just $4 million.
Using the previous example with proper planning:
Husband dies, $4 million goes into a credit shelter trust, $3 million goes to wife directly.
Wife later dies with $3 million in her estate (under the $4 million exemption).
Illinois estate tax: $0.
The family saves $428,000 through proper estate planning.
Essential Estate Planning Documents for Illinois Couples
Married couples’ estate planning in Illinois requires specific estate planning documents that work together to minimize estate tax and manage assets.
- Revocable living trust – The foundation of most estate tax planning strategies. Assets titled in the trust avoid probate and can be structured to create the credit shelter trust automatically at the first death.
- Pour-over will – Works with the trust to catch any assets not transferred to the trust during your lifetime, ensuring they’re distributed according to your trust plan.
- Powers of attorney – Both financial power of attorney and healthcare power of attorney allow your spouse (or another trusted person) to make financial decisions and medical decisions if you become incapacitated.
- Medical directives – Also called living wills, these legal documents specify your wishes for end-of-life medical care.
- Last will and testament – If you choose not to use a trust, properly drafted wills can still include provisions creating a credit shelter trust at death, though assets would go through probate court.
Most experienced estate planning attorneys recommend the trust-based approach for Illinois couples with assets approaching or exceeding $4 million.
Key Strategies for Illinois Estate Tax Planning for Couples
Beyond credit shelter trusts, Illinois estate tax planning for couples involves several effective strategies.
- Lifetime gifting – Illinois has no gift tax. Make strategic gifts to reduce your taxable estate. Annual exclusion gifts ($19,000 per person in 2025-2026) don’t count against any exemption.
- Life insurance planning – Life insurance death benefits you own count in your estate. An irrevocable life insurance trust (ILIT) owns the policy instead, removing death benefits from both spouses’ estates.
- Asset titling strategies – How you title assets matters for estate tax planning. The estate planning process includes reviewing all asset titles and adjusting them to support your strategy.
- Charitable planning – Assets left to charities aren’t subject to estate tax. Charitable remainder trusts provide income during life while reducing your taxable estate.
- Business succession planning – Proper planning reduces estate tax while ensuring a smooth business transition.
Each couple’s situation requires a tailored approach based on asset types, family dynamics, liquidity needs, and goals.

Why Work With an Estate Planning Attorney for Couples Planning
Many attorneys offer estate planning services, but Illinois estate tax planning for couples requires specific knowledge and experience.
- Understanding Illinois’s unique rules – Not all estate planning lawyers fully grasp the implications of Illinois’s lack of portability and how it affects married couples’ estate planning in Illinois.
- Coordinating multiple documents – Effective planning requires all your estate planning documents to work together seamlessly. A trust that doesn’t coordinate with beneficiary designations or asset titling creates problems.
- Addressing both spouses’ needs – The estate planning process should consider what happens at the first death and ensure the surviving spouse has sufficient access to assets while still preserving estate tax benefits.
- Practical, not just theoretical – Some attorneys create plans that look good on paper but don’t work in real life. Our law firm focuses on plans that actually function when your family needs them.
- Clear explanations – Estate tax planning is complex. We explain your options in plain English, so you understand how the strategies work and can decide what makes sense for your family.
A client recently shared, “We’d been putting off estate planning because it seemed overwhelming. The process was straightforward, and now we have peace of mind knowing our kids will inherit what we’ve built, not just what’s left after estate taxes.”
Common Mistakes in Estate Tax Planning for Illinois Couples
People often make predictable mistakes when handling Illinois estate tax planning for couples.
- Just using simple wills – Basic wills that leave everything to the surviving spouse waste the first spouse’s $4 million exemption.
- Assuming federal rules apply – Many people hear about federal portability and assume it applies in Illinois. It doesn’t.
- Not funding the trust – Creating a beautiful trust but never transferring assets into it. The trust can’t work if it doesn’t own anything.
- Wrong beneficiary designations – Retirement accounts and life insurance with simple spousal beneficiary designations bypass your trust and estate tax planning.
- Outdated plans – Creating an estate plan when assets totaled $3 million and never updating it as values grew to $7 million.
- One spouse does everything – One spouse handles all finances while the other knows nothing. When the informed spouse dies first, the surviving spouse struggles.
- No liquidity planning – Having $6 million in assets but no cash to pay estate taxes without selling property at bad times.
Working with experienced attorneys who understand these pitfalls helps you create an estate plan that actually works.

When Couples Should Create or Update Their Estate Plan
Certain moments create natural opportunities for Illinois estate tax planning for couples.
Major life events to trigger planning:
- Marriage or remarriage
- Birth or adoption of children
- Reaching $3-4 million in combined assets
- Receiving an inheritance or selling a business
- Significant appreciation in assets
- Retirement or diagnosis of serious illness
Even without a specific trigger, married couples’ estate planning in Illinois should be reviewed every 3-5 years to remain current with your wishes, asset values, and the law.
Coordinating With Your Financial Advisor
Estate planning works best when coordinated with your overall financial plan.
Your estate planning attorney should work alongside your financial advisor, financial planner, accountant, and other professionals. This coordination ensures investment strategies, beneficiary designations, life insurance structure, and tax planning all support your estate plan and protect assets effectively.
Many people find it helpful to have their estate planning attorney and financial advisor consult together to ensure everyone works toward the same goals of minimizing taxes and protecting loved ones.

Frequently Asked Questions
- How much can married couples protect from the Illinois estate tax?
- With proper Illinois estate tax planning for couples using credit shelter trusts, married couples can protect up to $8 million from Illinois estate tax. Without proper planning, couples can only protect $4 million because Illinois doesn’t allow portability of unused exemptions between spouses.
- What is a credit shelter trust, and why do Illinois couples need one?
- A credit shelter trust (also called a bypass trust) allows married couples’ estate planning in Illinois to use both spouses’ $4 million exemptions instead of just one. When the first spouse dies, up to $4 million goes into the trust, using that spouse’s exemption. The surviving spouse can benefit from the trust, but its assets aren’t included in their taxable estate, preserving their own $4 million exemption.
- Can we just leave everything to each other and avoid the estate tax?
- The unlimited marital deduction lets you leave everything to your spouse tax-free at the first death. However, this wastes the first spouse’s $4 million exemption. When the second spouse dies, their estate can only use one $4 million exemption, potentially owing significant estate tax that proper planning would have avoided.
- Do we need a trust, or will basic wills work?
- Basic wills can include provisions to create a credit shelter trust at death, but assets must go through probate court (a time-consuming legal process). Most experienced estate planning attorneys recommend revocable living trusts for couples with assets over $4 million. Trusts avoid probate, provide more flexibility, and make the estate planning process smoother for your family.
- How often should we review our estate plan?
- Conduct periodic reviews every 3-5 years or after major life events. As your assets grow, what worked at $3 million may not work at $6 million. Tax laws change, family circumstances evolve, and conducting periodic reviews ensures your plan remains effective at protecting your family.
- What if one spouse has more assets than the other?
- Asset distribution between spouses can be adjusted during your lifetime to balance estates and maximize the use of both exemptions. Your estate planning attorney can help you decide if rebalancing assets makes sense for your situation and how to do it properly.
