Navigate 2025’s $13.99M estate tax exemption and inheritance tax limits. Expert strategies before the 2026 sunset. Essential planning guide for wealthy families.

The landscape of estate tax planning has reached a critical juncture in 2025. With federal estate tax exemptions at historic highs of $13,990,000 per person, wealthy families face both unprecedented opportunities and looming uncertainty as these enhanced exemptions approach their scheduled expiration at year-end.

Understanding today’s estate tax exemption rules isn’t just about compliance—it’s about seizing a time-limited window to protect generational wealth. Whether you’re a high-net-worth individual, family business owner, or advisor serving affluent clients, the strategies you implement in 2025 could save millions in future tax obligations.

Understanding the Current Federal Estate Tax Exemption

2025 Federal Estate Tax Numbers

The federal gift and estate tax exemption amount, as well as the exemption from generation-skipping transfer (GST) tax, increased from $13,610,000 to $13,990,000 in 2025—an increase of $380,000 per person. For married couples, this translates to a combined exemption of $27,980,000 when properly structured.

The annual gift tax exclusion also received an inflation adjustment, increasing to $19,000 per donee per donor, or $38,000 for married couples making joint gifts. This represents a $1,000 increase from 2024 levels.

How Estate Tax Exemptions Work

The estate tax is a tax on your right to transfer property at your death, consisting of an accounting of everything you own or have certain interests in at the date of death. The IRS uses fair market value, not your original purchase price, to calculate your gross estate.

After accounting for deductions such as mortgages, administration expenses, and transfers to surviving spouses or qualified charities, the remaining “taxable estate” is subject to federal estate tax rates reaching 40% for amounts exceeding the exemption threshold.

Sarah Martinez, a certified financial planner from Austin, Texas, recently shared her experience: “One of my clients was shocked to learn that his $15 million estate would face a $400,000 tax bill in 2025, even with the high exemption. We immediately began implementing gifting strategies to maximize his exemption usage before the sunset.”

The 2026 Estate Tax Cliff: Why Timing Matters

Understanding the Sunset Provision

Perhaps the most critical aspect of current estate planning is the impending “tax cliff.” The federal exemption amounts under the Tax Cuts and Jobs Act of 2017 are scheduled to sunset at the end of 2025, decreasing on January 1, 2026, to a base amount of $5,000,000 (plus an inflation adjustment).

The exemption will be adjusted for inflation, estimated to be 3% per year, resulting in an exemption of about $9.3 million in 10 years from 2025. This dramatic reduction means that estates currently well below the tax threshold could face substantial tax obligations beginning in 2026.

Real-World Impact Examples

Consider a married couple with a $20 million estate. Under 2025 rules, their estate passes tax-free to heirs. However, under post-2026 rules (assuming roughly $10 million inflation-adjusted exemption), their estate would face approximately $4 million in federal estate taxes—a 40% tax on the $10 million excess.

James Thompson, an estate planning attorney from Chicago, explains: “I have clients who never thought they’d need sophisticated planning suddenly realizing they need to act now. A family farm worth $12 million might seem safe today, but could face a $800,000+ tax bill starting in 2026.”

State Estate Tax and Inheritance Tax Considerations

Varying State Approaches

While federal exemptions grab headlines, state-level inheritance tax limits create additional complexity. Several states maintain much lower exemption thresholds:

• Illinois: $4,000,000 estate tax exclusion amount
• Minnesota: $3,000,000 estate tax exemption
• New York: $7,160,000 estate tax exemption amount

Importantly, unlike the federal estate tax exemption, state estate tax exemptions are not portable between spouses in these jurisdictions.

The New York “Tax Cliff” Problem

New York presents a particularly harsh scenario. Once the value of a New York taxable estate exceeds 105% of the New York estate tax exemption amount, the New York estate tax is assessed on the full value of such New York taxable estate at a rate of 16%. This means an estate valued at $7.6 million would face tax on the entire amount, not just the excess.

Inheritance Tax vs. Estate Tax

Some states, including New Jersey and Pennsylvania, impose inheritance taxes on beneficiaries rather than estate taxes on the estate itself. A New Jersey inheritance tax may be imposed on property transferred from a decedent to a beneficiary, depending on the relationship between the decedent and the beneficiary.

Strategic Planning Opportunities for 2025

Maximizing Annual Exclusion Gifts

The increased annual exclusion provides immediate planning opportunities. A married couple with four children and eight grandchildren could transfer $456,000 annually ($19,000 × 12 recipients × 2 spouses) without using any lifetime exemption.

Planning Tip: Consider funding 529 education savings plans for multiple years at once. You can contribute five years’ worth of annual exclusions upfront ($95,000 per beneficiary, or $190,000 for married couples) while using a special election to spread the gift across five years for gift tax purposes.

Grantor Trust Strategies

Advanced planners often utilize grantor trusts to amplify exemption usage. By paying income taxes on trust earnings, the grantor makes additional tax-free transfers to beneficiaries without using additional exemption.

Spousal Lifetime Access Trusts (SLATs)

Through proper planning, you can take advantage of some or all of the current exemption amount while maintaining access to these gifted assets, if needed. Among the techniques that may be considered are Spousal Lifetime Access Trusts (SLATs).

SLATs allow one spouse to transfer assets to a trust benefiting the other spouse and descendants, using their lifetime exemption while potentially retaining indirect access to the assets through the beneficiary spouse.

Business Succession and Estate Planning

Valuation Discounts

Family business owners should consider transferring business interests before values appreciate further. Properly structured transfers of minority interests or non-controlling shares may qualify for valuation discounts of 20-40%, effectively multiplying exemption usage.

Case Study: The Johnson family owned a manufacturing business valued at $25 million. By gifting 60% ownership interests to their children through a family limited partnership, they utilized only $15 million of exemption (due to minority interest and marketability discounts) while transferring $25 million in underlying value.

Buy-Sell Agreements

Well-structured buy-sell agreements can establish estate tax values for business interests while providing liquidity for estate tax payments. The IRS generally respects fair market value determinations made through arm’s-length buy-sell agreements.

Retirement Account Planning Considerations

Required Minimum Distribution Changes

For qualified retirement plan accounts, the applicable age for starting required minimum distributions is now age 73 for individuals who attained age 72 after December 31, 2022. This delay provides additional tax-deferred growth opportunities.

Roth Conversion Strategies

Converting traditional retirement accounts to Roth IRAs during lower-income years can reduce future estate values while providing tax-free growth for beneficiaries. The current law has eliminated pre-death RMDs from Roth accounts in 401(k) and 403(b) plans starting in 2024.

Portability Elections and Spousal Considerations

Understanding Portability

The ability to transfer a decedent’s unused federal estate tax exemption amount to the decedent’s surviving spouse by filing a federal estate tax return (referred to as “portability”) remains in effect for 2025.

However, portability has limitations:

• Only available at the federal level
• Limited to the last deceased spouse’s unused exemption
• Must be elected within specific time frames

Late Portability Elections

The period for a late portability election remains five years after the decedent’s date of death. This provides flexibility for families who initially thought they wouldn’t need the deceased spouse’s exemption.

Important Note: Even if you don’t think you’ll need portability, filing an estate tax return to preserve this option often makes sense given the pending exemption reduction in 2026.

International Considerations

Non-Resident Estate Planning

Foreign nationals with U.S. assets face much lower estate tax exemptions—typically only $60,000. Proper structure using foreign trusts, treaty benefits, or life insurance can help mitigate U.S. estate tax exposure.

Pre-Immigration Planning

Individuals planning to become U.S. residents should consider pre-immigration planning strategies, as U.S. tax rules will apply to their worldwide estates once they become tax residents.

Common Planning Mistakes to Avoid

Waiting for Certainty

Many families delay action hoping for legislative clarity about 2026 exemption levels. However, effective planning often takes months to implement, and waiting risks losing opportunities.

Maria Rodriguez, a tax partner at a major accounting firm, warns: “I see clients who want to wait until December 2025 to act. But implementing a sophisticated gifting strategy with proper valuations, legal documentation, and family coordination can easily take 6-9 months.”

Ignoring State Law Differences

Failing to consider state estate tax implications can result in unnecessary tax obligations. Multi-state families should carefully consider domicile choices and trust situs decisions.

Over-Gifting

Some families, panicking about the sunset, consider gifting beyond their comfort level. Remember that the current exemptions are historic highs—even a reduced exemption starting in 2026 will provide substantial protection for most families.

Frequently Asked Questions

Q: What happens if I use my full exemption in 2025 and the law changes?

A: The IRS has confirmed that properly completed transfers using current exemption levels will remain protected even if exemptions decrease. You won’t face “clawback” taxation on previously exempted transfers.

Q: Should I consider making large gifts if I’m not certain about my financial security?

A: Consider techniques like SLATs or installment sales to trusts that allow some continued access or economic benefit while still achieving exemption usage. Don’t jeopardize your financial security for tax planning.

Q: How does the state where I live affect my planning options?

A: State residence significantly impacts estate tax exposure. Some states have no estate tax, while others impose tax at much lower thresholds than federal levels. Consider your long-term residence plans as part of your estate strategy.

Q: Is it too late to start planning in 2025?

A: While earlier planning provides more options, significant strategies can still be implemented throughout 2025. However, complex structures requiring valuations or family negotiation need adequate time for proper execution.

Q: How do I determine the value of my estate for planning purposes?

A: Engage qualified appraisers for business interests, real estate, and other non-liquid assets. Consider that estate values for tax purposes may differ from net worth calculations for financial planning.

Taking Action: Next Steps

The window for maximizing historically high estate tax exemptions closes at the end of 2025. Whether you’re protecting a family business, preserving wealth for future generations, or simply trying to minimize tax obligations, the time for action is now.

Start by working with qualified estate planning professionals who understand both current opportunities and the complexities of implementation. Consider engaging a team including estate planning attorneys, tax advisors, and financial planners who can coordinate comprehensive strategies tailored to your family’s unique circumstances.

Don’t let this unprecedented opportunity pass. The difference between action and inaction in 2025 could be measured in millions of dollars of additional taxes for the next generation.
