You built a plan. You reviewed it. You feel reasonably good about where things stand.
But there is one scenario most couples have never actually run.
What does this plan look like if only one of us is here?
Most families avoid that question. Not because they are careless. Because it is uncomfortable to plan for something you hope never happens. But the families who work through it consistently come out the other side with something most people never have: a plan that was built for both of them, and holds up for either one.
Here is what actually changes when one spouse dies, why it catches most families off guard, and three specific things couples can do now while both of them are still here to make the decisions.
When One Spouse Dies, Four Things Change at the Same Time
Most people think about the income loss first. That is the most visible part. But it is not the only part. The pieces most couples miss are the ones that hit hardest.
1. One Social Security check stops.
The survivor keeps the larger of the two checks. The smaller one disappears permanently. For a couple receiving $4,200 per month combined, that may drop to $2,400 overnight — a 43 percent reduction in income before a single expense changes.
The mortgage does not drop by 43 percent. The grocery bill does not drop by 43 percent. Utility bills, insurance, and property taxes do not change because one person is gone. The income does.
2. The tax situation changes — and usually not in the survivor’s favor.
A married couple files taxes together. A surviving spouse files as a single person. Single-filer tax brackets are narrower than joint-filer brackets. In 2026, a married couple stays in the 22 percent bracket up to $100,800 of taxable income. A single filer hits that same 22 percent bracket at just $50,401. (Source: IRS Revenue Procedure 2025-32.)
The same income that fit comfortably within the joint bracket may push a surviving spouse into a higher bracket as a single filer. More tax on less income. That combination hits harder than either one would alone.
3. Medicare costs may go up.
Medicare charges higher premiums to individuals above certain income thresholds. In 2026, the income cutoff for a married couple is $218,000. For a single person, it drops to $109,000 — roughly half. A surviving spouse who receives pension income, IRA distributions, or Social Security may cross that single-filer threshold even while receiving less total income than the couple did together.
The result: higher Medicare premiums on lower income, in the same year as the loss.
4. The portfolio carries more weight alone.
With one income source gone and expenses largely unchanged, the portfolio is often asked to fill a larger monthly gap. At the same time, required minimum distributions from IRAs do not pause. The surviving spouse still takes those distributions, still pays tax on them — and now does it all as a single filer.
According to research from Vanguard, widowed investors are more likely to make reactive portfolio decisions than married investors — particularly in the first 24 months after losing a spouse. Having a clear withdrawal plan in place before that moment matters more than most couples realize.
Why This Catches Families Off Guard

What This Looks Like in Real Numbers
Hypothetical Scenario:
Robert and Carol are both 68. Robert receives $2,400 per month in Social Security. Carol receives $1,800. Combined, their household takes in $4,200 from Social Security each month, plus a $1,500 monthly distribution from their IRA. Total monthly income: $5,700. They file taxes jointly and pay standard Medicare Part B premiums of $202.90 per person.
Carol passes away. Robert now receives only his $2,400 check. The $1,800 check stops. He continues the $1,500 IRA distribution to cover expenses. His total monthly income: $3,900 — a 32 percent drop.
But here is what Robert did not see coming. As a single filer, his $1,500 monthly IRA distribution may push his modified adjusted gross income above the Medicare single-filer income threshold. His Medicare premiums may increase. His tax rate on the same IRA distribution may be higher than when he and Carol filed jointly. More of his Social Security may now be subject to federal income tax because the tax thresholds for single filers are lower.
Individual results will vary. This illustration is for educational purposes only and does not represent any specific client situation. Consult a qualified financial, tax, or legal professional before making any financial decisions.
This is not an unusual outcome. It is what the numbers often look like for a household that planned well as a couple but never stress-tested the plan for one. The gap between what Robert expected and what actually arrived is not because he did anything wrong. It is because the plan was only built for two.
Why Most Retirement Plans Do Not Account for This
Most retirement plans are built around the couple as a unit. Income projections show two checks, often with inflation assumptions that were set years before costs started rising at 3.6 percent per year. Tax projections use joint filing. Spending assumptions use shared expenses. That is the right starting point.
But it is only half the picture. A 2022 LIMRA study found that 60 percent of widows and widowers reported that their household financial situation was worse than expected in the first two years after losing a spouse. The most common reason cited was not the emotional difficulty. It was the financial surprises they did not see coming.
The families who avoid the worst financial surprises are not necessarily the ones with the most money. They are the ones whose plan was designed to hold up for either person.
Three Things Couples Can Do Now
The survivor income gap is not fixed. There are specific decisions that reduce it. What makes them powerful is not that they work in isolation. Each one interacts with the others, and the greatest benefit comes from coordinating them together. Here are the three that tend to make the largest difference.
Maximize the higher earner’s Social Security benefit.
The higher earner’s Social Security benefit at the time of death becomes the permanent income floor for the surviving spouse. Every month that person delays past their full retirement age, their benefit grows by two-thirds of one percent — which works out to 8 percent per year, guaranteed by federal law, up to age 70. (Source: Social Security Administration, Delayed Retirement Credits.)
If the higher earner claims at 62 rather than 70, the monthly benefit is permanently reduced by up to 30 percent. For a person whose benefit at 70 would be $3,000 per month, claiming at 62 may lock it at approximately $2,100. That is a $900-per-month difference. For the surviving spouse who may live another 20 to 25 years, that gap compounds into a very large number.
For pre-retirees: If the higher earner has not yet claimed, this may be the single most impactful decision remaining in your plan. Run the numbers before the decision gets made.
When one spouse dies, the surviving spouse files taxes as a single person. Single-filer brackets are narrower. A Roth conversion made while both spouses are alive and filing jointly uses the wider joint brackets. The taxes are paid now, at potentially lower rates. The survivor draws from the Roth account later, potentially tax-free, as a single filer.
The window for this strategy is the period between retirement and age 73, when required minimum distributions begin. Required minimum distributions are mandatory. Roth conversions are a choice. Once RMDs start, the mandatory distributions reduce the flexibility to convert additional funds at favorable rates. According to Fidelity Investments, retirees who convert traditional IRA funds to Roth between ages 65 and 72 may reduce their long-term tax exposure significantly, particularly in survivor scenarios.
Tax treatment of Roth conversions depends on individual circumstances. Consult a qualified tax professional before converting.
Review and update all beneficiary designations.
Retirement accounts, life insurance policies, and annuities all pass by beneficiary designation — not by will. If the form on file is outdated, the account goes where the old form says, regardless of what the will states.
The American Association of Retired Persons estimates that outdated beneficiary designations are one of the most common and costly estate planning errors for families over 60. A designation made 15 years ago may list an ex-spouse, a deceased parent, or a child whose circumstances have changed. None of that shows up in the estate plan unless someone checks.
A full review takes about 30 minutes. It should happen every three years or after any major life change: a marriage, a divorce, a birth, a death. In Pennsylvania, there is additional incentive to get this right. PA inheritance tax is 0 percent on transfers to a surviving spouse, but 4.5 percent on transfers to children. An outdated designation can route assets to the wrong beneficiary and generate an unnecessary tax bill in the same year as the loss.
Beneficiary designation rules vary by account type and applicable state law. An estate planning attorney can confirm whether your current designations align with your intentions.
The Conversation Most Couples Keep Putting Off
Most couples avoid this conversation not because they are careless, but because it is hard to sit down and plan for something you hope never happens. That is completely understandable.
But the financial consequences of not having it are real. A 2024 T. Rowe Price study found that surviving spouses who had discussed a survivor income plan with a financial advisor before the loss reported significantly higher financial confidence and lower anxiety in the two years following the death of their spouse compared to those who had not.
The best time to run the survivor scenario is while both of you are here, calm, and in a position to make thoughtful decisions. Not in the middle of grief, when every financial choice feels permanent and overwhelming.
“The question to ask is not just ‘do we have enough?’ It is ‘does this plan still work if only one of us is here to use it?'”
If something in this article raised a question about your own plan, that is the conversation worth having while both of you are still here to make the decisions together.
