Widow(er) Finances: Portability of Estate Tax Exemption

The financial aftermath of a spouse's death arrives in waves. The immediate demands—death certificates, notifying financial institutions, managing funeral arrangements—overlap with decisions that have significant long-term financial consequences and that feel impossible to make clearly while grieving. Understanding the critical financial steps and deadlines in advance—or having a trusted advisor who does—can prevent irreversible mistakes during the most difficult period most people experience.

Among the most consequential and least understood provisions in estate law for surviving spouses is estate tax exemption portability—a provision that allows a surviving spouse to use the deceased spouse's unused estate tax exemption. For couples whose combined estate exceeds or may eventually exceed the individual federal exemption, the failure to elect portability within the required timeframe is an irrecoverable error.

PORTABILITY OF THE ESTATE TAX EXEMPTION: WHAT IT IS

Each individual has a federal lifetime estate and gift tax exemption—$13.61 million in 2024, indexed annually for inflation. Any amount above this exemption is subject to federal estate tax at rates up to 40%.

Historically, each spouse used their own exemption. If the first spouse to die had a $13.61 million exemption and their estate passed entirely to the surviving spouse (using the unlimited marital deduction with no estate tax), that first spouse's exemption was wasted—the surviving spouse still had only their own $13.61 million exemption when they died.

Portability, introduced by the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and made permanent in 2012, allows the surviving spouse to "port" the deceased spouse's unused exemption. The surviving spouse's effective exemption becomes their own exemption plus the deceased spouse's unused exemption.

Example: Spouse A dies in 2024 with a $13.61 million exemption, having made no taxable gifts during life. Their entire estate passes to Spouse B through the unlimited marital deduction—no estate tax owed. Spouse B elects portability. Spouse B now has a $27.22 million combined exemption ($13.61 million own + $13.61 million ported). When Spouse B dies, the combined exemption applies to their estate.

Without portability election: Spouse B has only their $13.61 million exemption at their death.

For a couple with a combined estate of $20 million, the difference between porting and not porting could be $40% × ($20 million - $13.61 million) = $2,556,000 in avoidable estate tax.

THE PORTABILITY ELECTION: THE DEADLINE AND HOW TO MISS IT

The portability election is made by filing a federal estate tax return (Form 706) for the deceased spouse's estate. This filing is required even if no estate tax is owed—its purpose is to elect portability, not to pay tax.

The deadline for filing Form 706 to elect portability is nine months from the date of death, with a six-month automatic extension available (bringing the window to 15 months total from death).

This deadline is frequently missed because:

Surviving spouses don't know the election exists. Without an estate attorney or financial advisor who proactively identifies the portability issue, many surviving spouses never file. They are grieving, overwhelmed, and unaware that an estate tax return is required even when no estate tax is owed.

The estate is below the current threshold, making the return seem unnecessary. A couple with a $6 million estate today isn't subject to estate tax at current exemption levels—but the current exemption is scheduled to sunset in 2026, potentially reverting to approximately $7 million per individual. A couple who fails to port because the estate was "clearly below threshold" may find that the surviving spouse's estate exceeds the reverted threshold decades later.

The IRS has provided relief for late portability elections in some circumstances. Revenue Procedure 2022-32 allowed a simplified late election process for estates where the surviving spouse is still alive and the estate was below the filing threshold. This relief is available for up to five years after the decedent's death for qualifying estates, but it requires affirmative action—it does not happen automatically.

IMMEDIATE FINANCIAL ACTIONS FOR SURVIVING SPOUSES

Beyond portability, several financial tasks require immediate or near-term attention:

Death certificates: Order at least 10 to 15 certified copies. Each financial institution, insurance company, and government agency will require an original or certified copy. Undershooting on copies creates delays when additional copies must be reordered.

Notify Social Security immediately: If the deceased spouse was receiving Social Security benefits, the Social Security Administration must be notified promptly. SSA does not allow beneficiaries to keep benefits paid for any month in which the recipient died. Benefits paid for the month of death must be returned. If direct deposit arrived after death, the bank is required to return it.

Survivor benefits: Apply for any Social Security survivor benefit you're entitled to. A surviving spouse can receive the higher of their own retirement benefit or the deceased spouse's benefit. The survivor benefit is maximized by the deceased spouse having delayed claiming to age 70—the surviving spouse receives that higher amount for life.

Inherited IRA rules: An inherited IRA from a deceased spouse has unique treatment compared to inherited IRAs from other individuals. A spousal beneficiary can elect to roll the inherited IRA into their own IRA—treating it as if they were the original owner. This is the most tax-efficient option for most surviving spouses because it preserves the ability to delay RMDs (required minimum distributions) until the surviving spouse's own RMD age and allows Roth conversion planning on the inherited assets. The alternative—maintaining it as an inherited IRA—subjects it to RMD rules based on the surviving spouse's age, which may require earlier distributions.

Survivor spousal benefits from pension plans: If the deceased spouse had a defined benefit pension, the plan may provide a survivor annuity. The original election made when the pension began determines what, if anything, the surviving spouse receives. If the pension elected a single-life annuity (higher monthly payment, no survivor benefit), the surviving spouse receives nothing. If it elected a joint and survivor annuity, the survivor benefit continues. Review the pension documentation immediately.

BENEFICIARY ACCOUNT CLAIMS

Accounts with TOD (transfer-on-death) or POD (payable-on-death) designations transfer directly to the named beneficiary upon presentation of a death certificate. These accounts bypass probate and can often be claimed relatively quickly.

For retirement accounts (IRA, 401(k)), the claiming process depends on how the surviving spouse is named:

As spousal beneficiary: The surviving spouse can claim the account and roll it into their own IRA, elect to remain as the beneficiary of the inherited IRA, or (for 401(k) accounts) roll it to an IRA. The spousal rollover is almost always the most flexible and tax-efficient option.

As non-spousal beneficiary (this occurs in second marriages where the deceased left accounts to prior family): The 10-year distribution rule applies—the inherited IRA must be fully distributed within 10 years of the original owner's death.

ANNUAL TAX FILING CHANGES

The year of a spouse's death:

A surviving spouse can file as "married filing jointly" for the year in which the spouse died, using the joint standard deduction and tax brackets for one final year. This is generally more favorable than filing as a single taxpayer.

For two years following the year of death (if the surviving spouse has dependent children), the "qualifying surviving spouse" filing status allows continued use of joint tax rates—a significant benefit over the single filer brackets.

After the qualifying period, the surviving spouse files as a single taxpayer. The standard deduction drops from $29,200 (married filing jointly, 2024) to $14,600 (single, 2024). This is a meaningful income tax increase that affects cash flow planning.

AVOIDING FINANCIAL DECISIONS TOO SOON

The financial industry has documented the tendency for recently widowed people—particularly those receiving life insurance proceeds, pension lump sums, or inheritances—to make major financial decisions while still in acute grief, often with poor outcomes.

The standard guidance: avoid major financial decisions in the first year after a spouse's death. Park life insurance proceeds and any inherited liquid assets in a high-yield savings account or money market fund while grief runs its course. Major decisions about whether to sell the home, how to invest the life insurance proceeds, whether to purchase an annuity, and similar commitments are better made after the most acute phase of grief has passed.

This is not passivity—it is the recognition that grief impairs judgment in measurable ways, and that the financial decisions made in this period have long-lasting consequences.

The most important financial actions in the first year: claim all survivor benefits, elect portability before the deadline, update estate planning documents, change beneficiary designations, and get a clear picture of the current financial situation. The decisions about how to deploy assets can wait.
