For years, affluent families, business owners, executives, and physicians prepared for the possibility that the historically high federal estate and gift tax exemption would be reduced after 2025.
The One Big Beautiful Bill Act changed that outlook.
Beginning in 2026, the federal exemption increases to $15 million per person and $30 million per married couple, with future inflation adjustments expected. Just as important, Congress made the higher exemption permanent, providing greater certainty for long-term estate planning decisions.
While the change reduces federal estate tax exposure for many families, it does not eliminate the need for planning. Existing gifting strategies, trust structures, succession plans, and wealth-transfer goals may need to be reviewed under the new rules.
Premium Tax Planners helps families evaluate how these changes affect long-term wealth preservation through coordinated estate planning and estate and trust tax services.
This guide explains what the 2026 exemption increase means and the planning opportunities affluent families should consider moving forward.
Key Takeaways
- The federal estate and gift tax exemption increases to $15 million per person and $30 million per married couple in 2026, creating greater flexibility for wealth-transfer planning.
- The One Big Beautiful Bill Act (OBBBA) made the higher exemption permanent, reducing uncertainty around long-term estate planning decisions.
- Illinois residents still face a $4 million state estate tax exemption, making state-level planning critical even when federal estate taxes are not a concern.
- Existing trusts, gifting strategies, portability elections, and succession plans should be reviewed to ensure they still align with current law.
- Lifetime gifting, trust planning, and coordinated federal-state strategies remain important tools for preserving wealth across generations.
The 2026 Federal Exemption: $15 Million Per Person, $30 Million Per Couple
Starting in 2026, the federal estate and gift tax exemption increases to $15 million per individual and $30 million for married couples. For many affluent families, the change reduces immediate federal estate tax concerns and creates greater flexibility around gifting, trust planning, and wealth transfer strategies. Just as important, the legislation provides more certainty than many advisors expected heading into 2026.
How OBBBA Made the Higher Exemption Permanent
The permanence of the increase may prove just as valuable as the increase itself.
Temporary tax provisions often force families to make planning decisions based on uncertainty rather than strategy. Advisors were previously helping clients prepare for multiple possible outcomes, including a substantially lower exemption beginning in 2026.
OBBBA largely removed that uncertainty.
By making the higher exemption permanent, Congress provided affluent families with a more stable framework for long-term planning. Business owners can evaluate succession plans with greater clarity. Families considering significant gifts can assess opportunities without worrying that the exemption may disappear within a few years.
The result is a planning environment where decisions can be driven by family objectives rather than legislative deadlines.
That distinction is particularly important for households evaluating the implications of the lifetime exemption increase over multiple generations.
The 40% Rate That Still Applies Above the Exemption
While the higher exemption has received considerable attention, the federal estate tax itself has not disappeared.
Assets that exceed the available exemption remain subject to a 40% federal estate tax rate. For ultra-high-net-worth families, that continues to make proactive planning essential.
Even families that fall comfortably below today’s thresholds should avoid assuming they will remain there indefinitely. Successful businesses grow. Investment portfolios appreciate. Real estate values change over time.
A physician building a successful practice, an executive with concentrated stock holdings, or an entrepreneur preparing for a future liquidity event may find that today’s estate looks very different a decade from now.
The expanded estate tax exemption of 2026 creates more room for growth, but it does not eliminate the importance of planning for future growth.
The Illinois Trap: A $4 Million State Exemption That Didn’t Move
The higher federal exemption has led many families to assume estate taxes are no longer a concern. For Illinois residents, that assumption can be costly.
While the federal exemption increased significantly, the Illinois estate tax exemption remains $4 million, creating a substantial gap between federal and state planning considerations.
Why North Shore Families Can Clear the Federal Bar and Still Owe Illinois Tax
Consider a family with a net worth of $8 million, $10 million, or even $12 million.
Under the new federal rules, that family may have little reason to worry about federal estate taxes. Under Illinois law, the analysis can be very different.
Because the Illinois estate tax exemption remains substantially lower, many affluent households continue to face state-level estate planning considerations despite enjoying complete federal protection.
This issue frequently affects successful physicians, executives, and business owners whose wealth has accumulated gradually over time. They may never approach the federal threshold, yet still benefit from strategies designed to address Illinois estate tax exposure.
For families pursuing comprehensive North Shore tax planning, understanding how federal and state rules interact remains critical to preserving wealth across generations.
No Portability Between Spouses in Illinois
Another area in which Illinois diverges from federal law concerns portability.
Under federal rules, estate tax portability allows a surviving spouse to preserve a deceased spouse’s unused exemption amount, potentially increasing the total amount that can pass free of federal estate tax.
Portability has become an important planning tool because it creates flexibility and can reduce the need for certain tax-driven trust structures.
Illinois does not provide the same benefit.
As a result, married couples who rely solely on federal planning assumptions may miss opportunities to maximize available state exemptions. The difference becomes particularly important when reviewing older estate plans, trust structures, and wealth-transfer strategies.
The existence of federal estate tax portability should not lead families to assume state-level planning concerns have been addressed automatically.
What the Higher Exemption Changes About Your Plan
The higher estate tax exemption in 2026 changes more than tax exposure. It also changes the assumptions behind many existing estate plans.
Trust structures, gifting strategies, and succession plans designed around lower exemption amounts may warrant a fresh review under the current rules.
Reviewing Old Formula Bequests and Credit Shelter Trusts
Many estate plans contain formula-based provisions that automatically allocate assets based on the exemption available at the time of death.
When exemptions were lower, these structures often helped maximize tax efficiency. Today, the same provisions may operate differently because the exemption has increased so dramatically.
Credit shelter trusts remain valuable in many situations, particularly when asset protection and long-term wealth preservation are priorities. However, families should confirm that existing trust formulas still align with their goals.
The recent increase in the lifetime exemption gives affluent households an opportunity to evaluate whether older structures continue to serve their intended purpose or whether adjustments may be appropriate.
Portability and the Deceased Spousal Unused Exemption (DSUE)
The higher exemption also increases the value of estate tax portability.
Through the Deceased Spousal Unused Exemption, or DSUE, a surviving spouse may preserve a deceased spouse’s unused federal exemption. For married couples, this can create significant additional protection against future estate tax exposure.
One common misconception is that portability happens automatically.
In reality, the appropriate estate tax return generally must be filed to preserve the unused exemption. Families sometimes overlook this step because no estate tax appears due at the time of the first spouse’s death.
Years later, that missed election can become far more significant as assets appreciate and family wealth grows.
The larger exemption makes portability more valuable than ever, which is why it should remain a key part of the estate-planning conversation, even for families that currently sit well below federal thresholds.
Using the Exemption Before It Grows Past You
The expanded 2026 estate tax exemption of $15 million provides more room for future growth, but growth itself remains a key planning consideration. Businesses appreciate, investment portfolios compound, and real estate values change over time.
The families that benefit most from today’s exemption often take advantage of planning opportunities before future asset growth changes the picture.
Lifetime Gifting, Trusts, and Locking in Today’s Exemption
The federal estate and gift tax system operates as a unified framework, which means the gift tax exemption of 2026 generally corresponds with the federal estate tax exemption.
For affluent families, that creates meaningful planning opportunities.
Lifetime gifting can transfer appreciating assets outside the taxable estate while allowing future growth to occur beyond the reach of future estate taxes. Trust structures can provide additional flexibility by supporting family wealth-transfer objectives while maintaining varying levels of control, oversight, and asset protection.
The most effective strategies are rarely driven by taxes alone. They are designed around broader family goals, including business succession, multigenerational wealth transfer, charitable giving, and long-term asset preservation.
When integrated into a broader advanced tax planning strategy, the expanded exemption can provide opportunities that extend well beyond reducing future estate tax exposure.
Coordinating Federal and Illinois Strategy
Federal and state estate tax systems operate independently. A strategy that works well under federal law may leave important opportunities unaddressed under Illinois law. Effective planning requires both perspectives.
When a Plan That Works Federally Still Needs Illinois-Specific Structure
A family may have no federal estate tax exposure whatsoever and still benefit from state-focused planning.
This is where coordination becomes important.
Trust design, ownership structures, beneficiary arrangements, and gifting strategies can all influence how assets are treated under Illinois law. A plan that appears highly effective from a federal perspective may leave opportunities unaddressed at the state level.
For families whose estates exceed the Illinois estate tax exemption, thoughtful planning can help align federal and state objectives rather than forcing one set of rules to compete with the other.
This is often where specialized estate and trust tax services become valuable, particularly for families navigating complex asset structures, closely held businesses, or multigenerational wealth-transfer goals.
An Advisor’s Take: The Review Every HNW Family Should Do in 2026
The higher exemption creates flexibility, but it does not eliminate the need for review. Many trusts, gifting strategies, and succession plans were built around assumptions that no longer apply.
For affluent families, 2026 is an appropriate time to confirm that existing plans still align with both current law and long-term objectives.
Review Your Estate Plan While the Rules Are in Your Favor
The permanent increase in the estate tax exemption in 2026 creates one of the most favorable wealth-transfer environments affluent families have seen in years. The higher federal threshold expands planning flexibility, supports long-term gifting strategies, and reduces immediate concerns about federal estate taxes for many households.
At the same time, important planning considerations remain. State-level taxes, trust design, portability elections, business succession planning, and future asset growth continue to influence the effectiveness of wealth transfer from one generation to the next.
For physicians, executives, business owners, and high-net-worth families, the most valuable opportunity may not be the exemption itself. It may be the chance to revisit existing plans and ensure they still reflect today’s laws and tomorrow’s objectives.
