This issue is critical because Illinois' lack of estate tax portability creates a hidden financial liability for married couples. Proactive estate planning prevents the unnecessary erosion of family wealth, ensuring that assets are preserved for heirs rather than lost to state taxes due to common planning oversights.
Many Illinois married couples are unaware that state law fails to provide estate tax portability, a critical feature available at the federal level. While federal law allows a surviving spouse to utilize the deceased partner's unused exemption, Illinois law does not. Without proactive legal intervention, the $4 million state exemption per person can be permanently lost upon the first death, leaving the survivor with only a single exemption to cover the entire combined estate.
This oversight can lead to significant financial consequences, as Illinois applies its estate tax as a cliff, potentially triggering hundreds of thousands of dollars in unexpected taxes. To mitigate this risk, couples often utilize a credit shelter trust, also known as an AB or bypass trust. This strategic arrangement effectively preserves both spouses' exemptions, shielding up to $8 million of assets from state taxation rather than just $4 million.
Beyond immediate tax savings, these specialized trusts offer essential protections against future creditors and help manage complex family dynamics. Founding attorney Daniel Kravets emphasizes that this essential planning must occur while both spouses are living. By reviewing current estate plans, couples can secure their legacy and ensure their assets remain protected for future generations.
