You have done this on your own for thirty years. The savings are real, the house is paid down, and the retirement date you have in mind is not a fantasy. What is different about retirement planning for single women is that every number has to hold on its own: one income now, one Social Security check later, single-filer tax brackets, and one person to make the care decisions when the time comes.
Most retirement guidance assumes two of everything: two incomes to absorb a bad year, two Social Security checks with a survivor benefit to plan around, a joint return that softens required withdrawals, and a spouse who can sign a form when you cannot. A single woman with $1.5 million or more saved does not need the couple’s plan with one name deleted. She needs the five decisions below worked out on her own numbers.
This post walks through each one with 2026 figures: when to claim Social Security, how Roth conversions work on a single filer’s brackets, how to fund the years before Medicare from savings alone, how to plan long-term care without a default caregiver, and who acts for you if you cannot. One hypothetical composite runs through all five so you can see the arithmetic.
Why retirement planning for single women is different
A single woman’s plan comes with no backup. There is no second income to absorb a poor market in the first year of retirement, no survivor benefit to plan around, no joint tax return to soften required withdrawals, and no spouse with default legal authority if she is ill. A good plan replaces each of those with something written down, funded, and dated.
Three of the five decisions are really tax decisions. The Internal Revenue Service sets every single-filer threshold at roughly half the married figure, so the room for Roth conversions is smaller, the Medicare surcharge line arrives sooner, and required minimum distributions land on a return with no one to split them with. The table shows the 2026 numbers that drive the rest of this post.
| 2026 threshold | Single filer | Married filing jointly |
|---|---|---|
| Standard deduction | $16,100 | $32,200 |
| Top of the 12% bracket (taxable income) | $50,400 | $100,800 |
| Top of the 22% bracket (taxable income) | $105,700 | $211,400 |
| Top of the 24% bracket (taxable income) | $201,775 | $403,550 |
| First Medicare IRMAA surcharge tier (2024 modified AGI) | $109,000 | $218,000 |
Two things about that table. First, the Medicare surcharge is set by your income from two years earlier, so the 2026 premium looks at your 2024 return, and a conversion you do at 63 shows up in your Part B and Part D premiums at 65. Second, the brackets are on taxable income after the standard deduction, while the Medicare line is on modified adjusted gross income before it. The two do not line up, and a single filer runs into the Medicare line first.
The five decisions that are different for a single woman
1. Social Security is a longevity decision, not a survivor decision
For a married couple, the claiming decision is mostly about the survivor: which check should wait so that the larger one is the one that continues. A single woman has one check and no survivor, so the question is simpler. The only risk her portfolio cannot diversify away is a long life, and a benefit claimed at 70 is the one source of income that is guaranteed, rises with inflation, and cannot be outlived.
The numbers, from the Social Security Administration, for a full retirement age of 67: claiming at 62 pays 70% of the full benefit for life, and each year of waiting past 67 adds 8% in delayed retirement credits, to 124% at 70. On a $3,600 full-retirement-age benefit that is $2,520 a month at 62 against $4,464 at 70, before cost-of-living adjustments. The exception is a material change in health. Run the break-even on your own statement before you settle on either answer.
Waiting is affordable only if the years before 70 are funded from somewhere else, which is decision three.
2. Roth conversions happen on single-filer brackets, and the Medicare line comes first
The years between your last paycheck and age 70 are the lowest-income years you will have, and they are the Roth conversion window. A single filer has roughly half the room a couple has, and the Medicare surcharge line arrives at half the income, so the schedule is built differently: fill the 22% bracket in the years before Medicare income matters, then stop at $109,000 of modified adjusted gross income once it does.
The reason to do it is that required minimum distributions land on the same single return. Under current law, a woman born in 1960 or later takes her first required withdrawal at 75, and the Uniform Lifetime Table factor at that age is 24.6. A $3.7 million pre-tax balance produces a required withdrawal of about $150,000 in the first year, on top of Social Security, which puts a single filer in the 24% bracket and several tiers into the Medicare surcharge for life. Conversions do not move her out of the bracket; they cut the dollars taxed there and pull the surcharge back, which over 20 years is the larger saving. The Executive Woman’s Tax Playbook walks through the bracket-filling method in detail.
New Jersey taxes conversions as income and does not tax Social Security. From 62, the state’s retirement income exclusion may apply in years when total income is $150,000 or less, which lowers the state cost of conversions sized under the Medicare line.
3. The bridge years are funded from savings alone
Between the last paycheck and Medicare at 65, and then to Social Security at 70, spending comes from savings alone. For a couple, a second paycheck or a second check absorbs a bad first year. For a single woman, the plan has to build that margin in: a larger cash reserve, dividends turned to cash instead of reinvested, and a withdrawal order set before year one.
The order matters because it decides the tax. Idle cash and high-basis taxable lots go first, so the early years show almost no taxable income and the conversion room stays open. The pre-tax IRA is touched last, because every dollar taken from it is a dollar that could have been converted at a lower rate. Health coverage before 65 is priced for one adult on the marketplace, and the conversion income is usually too high for a premium subsidy, so the plan pays full price on purpose and takes the Roth room instead.
4. Long-term care has no default caregiver
Most couples absorb the first stretch of care at home, with a spouse doing the coordinating and much of the caring. A single woman does not have that layer, so the decision most couples defer is the one she has to make on paper, early: self-fund from a designated reserve, insure, or a hybrid life and long-term care policy.
Decide with a real premium in front of you. Get one hybrid quote before 60, when underwriting is easier, and compare it with the cost of earmarking a slice of the Roth balance as the care reserve. For many single women the policy is the better answer even when the arithmetic is close, because it also buys a care coordinator, which is the job a spouse would otherwise have done. Either way, the decision belongs in the plan now, reviewed every spring, so it is never made in a crisis by a sister or a niece.
5. Who acts for you if you cannot
A spouse can act without paperwork. A sister, a friend, or a professional fiduciary cannot. For a single woman the durable financial power of attorney and the health care proxy, which New Jersey calls a proxy directive, are the most important documents in the plan, and the most often missing. Name a first agent and a successor, and consider a professional fiduciary as the successor so the plan does not rest on one person who may one day need her own.
Then check the beneficiary forms, because they override the will. A 401(k) still naming a parent from 2009, a contingent line left blank, a taxable account with no transfer-on-death designation: each one is a thirty-minute fix and each one can send seven figures through probate. One New Jersey specific: transfers to a sibling are subject to the state inheritance tax above $25,000 at 11% to 16%, and transfers to nieces and nephews at 15% to 16%, and retirement accounts left to them are not exempt. A Roth left to a niece is tax-free federally and still taxed by New Jersey. That belongs on the agenda for the attorney meeting.
A worked example: one single woman, five decisions
Elena is a hypothetical composite, not a client. She is 55, single, a senior director at a New Jersey healthcare company, with $2.38 million invested: $1.15 million in a pre-tax 401(k), $155,000 in Roth accounts, $480,000 in a taxable account, $210,000 of vested employer stock, $220,000 of deferred compensation, and $110,000 in cash. She wants to stop at 60 and spend about $146,000 a year.
- Social Security. Her full-retirement-age benefit is about $3,600 a month. She waits to 70 for $4,464, because the bridge is funded from taxable money and deferred compensation, and the larger check is the only income she cannot outlive.
- Roth conversions. At 61 and 62 her taxable income is about $12,000 of dividends. After the $16,100 standard deduction, the top of the 22% bracket leaves room for a $109,800 conversion each year at a federal cost of $17,966, or 16.4%. From 63, the Medicare line caps conversions at about $97,000. Over nine years she moves roughly $540,000 to Roth and cuts her age-75 pre-tax balance from about $3.7 million to about $2.6 million, and the first required withdrawal from about $150,000 to about $107,000.
- The bridge. Years one to three are funded by idle cash and the employer stock sold down to a 10% ceiling, highest-basis lots first. Years four and five come from the taxable account. Deferred compensation, re-elected as five installments starting at 65, carries her to 70. The IRA is untouched until required withdrawals begin.
- Long-term care. She earmarks $350,000 of the Roth balance as the care reserve and gets one hybrid quote before 60. If the premium is under a threshold she sets, the policy replaces the reserve, because it comes with a care coordinator.
- Who acts. Her 401(k) still names her 84-year-old mother, and no one holds her power of attorney. Both are fixed before year end: sister as agent and primary beneficiary, nieces as contingents, a professional fiduciary as successor, and transfer-on-death added to the taxable account.
Every figure above is illustrative and depends on the assumptions stated. What carries over to any single woman’s plan is the order of work: each decision was made on single-filer numbers, and each was made on paper before it locked.
What to Do This Week
- Pull your Social Security statement from ssa.gov. Write down the benefit at 62, 67, and 70 in today’s dollars. The gap between the first and last number is the size of the longevity decision.
- Add up your pre-tax balances and project them to 75 at 6%. Divide by 24.6. That is the first required withdrawal on a single return, before Social Security. If the number is over $100,000, the Roth conversion window is worth modeling this year.
- Open every beneficiary form. Retirement accounts, life insurance, and the taxable account’s transfer-on-death designation. Fix any that name a parent, a former partner, or nobody on the contingent line.
- Ask one insurance agent for one hybrid long-term care quote. That way the self-fund-or-insure decision is made with a real premium instead of a guess.
- Name your agent and your successor. Decide who holds the durable power of attorney and the health care proxy, and who steps in if that person cannot. Then book the attorney.

Frequently Asked Questions
How is retirement planning different for a single woman?
Four things change. The years before Social Security are funded from savings alone, so the cash reserve and withdrawal order need more margin. Claiming Social Security is decided on longevity alone, since there is no survivor benefit to protect. Roth conversions and required withdrawals land on single-filer brackets, where the 2026 Medicare surcharge line is $109,000 instead of $218,000. And the care plan and legal documents must be arranged in advance, because no one has default authority.
When should a single woman claim Social Security?
For most single women with other assets to live on, waiting until 70 is the stronger choice. The benefit grows 8% a year past full retirement age, to 124% of the full benefit at 70, and it is the one income that rises with inflation and lasts as long as she does. The exception is a material change in health. Run the break-even on your own statement before deciding.
How much can a single filer convert to Roth in 2026?
There is no legal limit; the practical limit is the bracket and the Medicare line. In 2026 a single filer with little other income can convert up to about $121,800 before the standard deduction and the top of the 22% bracket are used up ($105,700 plus $16,100). Once Medicare premiums are in view, from about age 63, the ceiling becomes $109,000 of modified adjusted gross income, because income above that line raises Part B and Part D premiums two years later.
What legal documents does a single woman need for retirement?
At minimum: a durable financial power of attorney, a health care proxy (called a proxy directive in New Jersey), an updated will, and current beneficiary designations on every retirement account, with transfer-on-death on taxable accounts. Name a first agent and a successor, and consider a professional fiduciary as the successor so the plan does not rest on one person.
Does New Jersey tax an inheritance left to a niece?
Yes. New Jersey’s inheritance tax applies to transfers to nieces and nephews (Class D beneficiaries) at 15% to 16%, and to siblings (Class C) above $25,000 at 11% to 16%. Retirement accounts payable to them are not exempt, so a Roth IRA left to a niece is tax-free federally but still taxed by New Jersey. Transfers to charities are exempt.
