Many married couples wonder how high their net worth must be before the federal estate tax applies. The federal estate tax is a tax on the transfer of wealth at death, and the threshold is high, but it changes over time.
Planning around this tax involves understanding the lifetime exemption, portability for married couples, and how gifts during life interact with the estate tax calculation. The following sections break down the key thresholds and planning options.
| Married Couple Status | 2024 Federal Estate Tax Exemption per Spouse | Combined Exemption if Portability Used | Top Federal Estate Tax Rate |
|---|---|---|---|
| Unmarried Individuals | $13,610,000 | N/A | 40% |
| Married Couple (No Planning) | $13,610,000 each | $13,610,000 total | 40% |
| Married Couple (Full Portability) | $13,610,000 each | $27,220,000 total | 40% |
| Typical Planning Threshold | ≈$13.61M per spouse | ≈$27.22M combined | 40% on excess |
Understanding the Federal Estate Tax Exemption
The federal estate tax applies only to transfers above a very high exemption amount. For 2024, each individual can shield $13.61 million of assets from estate tax. This means that for a married couple, the first dollars of wealth up to approximately $27.22 million can generally pass tax free if the deceased spouse's unused exemption is properly used by the surviving spouse.
Congress sets and adjusts these exemption amounts periodically, so the actual number each year can vary. When a married couple's combined net worth stays below this combined exemption, federal estate tax is not due at the death of either spouse.
Portability and Married Couple Planning
What is Portability
Portability allows a surviving spouse to use any unused federal estate tax exemption from the deceased spouse. This effectively doubles the exemption for married couples who plan correctly, meaning that even if only one spouse has substantial assets, the couple can shelter up to twice the single exemption amount. Proper election on the first death is required to preserve this benefit.
How High Must Net Worth Be to Trigger Estate Tax
Threshold for a Married Couple
For federal estate tax purposes, a married couple is only subject to estate tax when the combined value of the taxable estate exceeds the exemption amount of the deceased spouse, unless the surviving spouse elects portability and the total historically exceeded the exemption. In practical terms, this means a couple must have a net worth above roughly $27.22 million in 2024 to risk federal estate tax on the portion above that threshold. Estates under that level typically do not owe federal estate tax.
Role of Taxable Estate and Deductions
Not everything a couple owns counts directly toward the taxable estate, because deductions for debts, administrative expenses, charitable bequests, and the marital deduction can reduce the taxable base. Planning must focus on the value of the taxable estate after these deductions rather than simply on total net worth.
Annual and Lifetime Gift Tax Considerations
Gifts During Life and the Unified Exemption
The same unified exemption that governs estate tax also applies to lifetime taxable gifts. Each person can gift up to the annual gift tax exclusion each year without using exemption, but larger gifts reduce the remaining lifetime exemption. For a married couple, each spouse has their own exemption, so strategic use of gifts can reduce future estate tax exposure while still below the overall exemption limits.
Key Takeaways for Married Couples

- Focus on taxable estate value rather than gross net worth when assessing exposure.
- Use annual gift exclusions and lifetime exemptions strategically to reduce future estate tax.
- Coordinate elections and documentation on the first death to maximize available exemptions.
- Work with tax and legal professionals to tailor strategies to the couple's specific assets and goals.
FAQ
Reader questions
Does the federal estate tax apply as soon as a married couple's net worth exceeds $27 million?
No, the tax applies only to the portion of the taxable estate that exceeds the applicable exemption amount, which is effectively doubled to about $27.22 million for many married couples who use portability. Below that threshold, federal estate tax generally does not apply.
What happens to the exemption if one spouse dies with an unused exemption?
The surviving spouse can elect portability on the federal estate tax return, allowing the unused exemption of the deceased spouse to be added to the surviving spouse's own exemption. This increases the total amount that can pass tax free during the surviving spouse's lifetime and at their death.
Can married couples reduce their taxable estate below the exemption through gifts?
Yes, by using their annual gift tax exclusion and lifetime exemption strategically during life, married couples can reduce the size of their taxable estates. Each spouse can make gifts up to the annual exclusion without affecting the lifetime exemption, while larger gifts can use part of the exemption to remove future appreciation from the estate.
How does the step-up in basis interact with estate planning for married couples?
Assets inherited from a deceased spouse typically receive a step-up in basis to their fair market value at death, which can reduce capital gains tax if sold later. This interacts with estate planning because the timing and manner of transfers can affect both estate tax exposure and the heirs' future income tax liability.
