Financial Planning for Couples in Their 70s: Distribution, Legacy & the RMD Decade

The 60s were the execution decade — Social Security timing, Medicare enrollment, Roth conversion window. By your 70s, most of those decisions are made. Required minimum distributions have started or are imminent. Both spouses are on Medicare. Social Security is flowing. The focus shifts decisively from building and converting to distributing and preserving — managing two mandatory withdrawal streams, avoiding Medicare surcharges that can add thousands per year, and structuring the estate that will eventually transfer to heirs or charity. The decisions that matter most now are less about growth and more about coordination: two sets of RMDs, two Medicare enrollments, two Social Security records, and eventually, what happens financially when one spouse dies.

RMD mechanics: two spouses, two schedules

Required minimum distributions are per-person obligations. Each spouse must take RMDs from their own traditional IRAs, 401(k)s, and other pre-tax accounts independently — there's no "couples RMD" or account combining across spouses.

The start age depends on birth year under SECURE 2.0:

• Born 1951–1959: RMDs begin at age 73.¹ If you or your spouse was born in this range, you reached (or are approaching) RMD age now.
• Born 1960 or later: RMDs begin at age 75.¹ A couple where one spouse is 73 and the other is 72 (born in 1953 and 1954) faces staggered RMD starts.

The first-year option and the two-RMD trap: Your first RMD can be taken by April 1 of the year after you reach RMD age — giving you extra time in year one. But if you delay the first RMD to April 1 of the following year, you must also take the second RMD by December 31 of that same year. That's two RMDs in one calendar year — doubling taxable income and potentially triggering a higher IRMAA tier for the year after that. For most couples, taking the first RMD in the year they turn 73 (or 75) avoids this bunching problem.

The RMD calculation: Divide your prior December 31 account balance by the IRS Uniform Lifetime Table divisor for your age. At age 73 the divisor is 26.5, at 75 it is 24.6, at 80 it is 20.2. A $700,000 balance at age 73 produces an RMD of about $26,400; at age 80 the same balance would produce about $34,700.¹ Both spouses calculate independently from their own balances.

Traditional IRA aggregation — 401(k) per-account rule: If either spouse has multiple traditional IRAs, the RMD can be calculated across all of them combined and withdrawn from any one account. 401(k) accounts do not aggregate — each former employer's 401(k) requires a separate RMD calculated and taken from that specific plan. Consolidating old 401(k)s into a single IRA before RMDs begin simplifies this substantially.

No lifetime RMDs from Roth accounts: Roth IRAs have never had lifetime RMDs. Roth 401(k) and Roth TSP accounts are also exempt from lifetime RMDs starting in 2024 (SECURE 2.0 § 325).¹ Roth balances can grow undisturbed for heirs.

QCD strategy: the most underused tool in the 70s

A Qualified Charitable Distribution (QCD) lets each spouse transfer up to $111,000 per year directly from a traditional IRA to a qualified 501(c)(3) charity.² For a couple, that's up to $222,000 per year in combined QCDs. The mechanics make this uniquely powerful:

• The amount counts toward your RMD for the year. If your RMD is $30,000 and you do a $30,000 QCD, you've satisfied the full RMD with no taxable income.
• The QCD is excluded from your gross income entirely. Unlike a regular charitable deduction (which reduces taxable income), a QCD never enters your MAGI at all. This matters for IRMAA: regular charitable deductions don't reduce MAGI; QCDs do.
• No itemizing required. Because the QCD is excluded from income rather than deducted, it benefits you even if you take the standard deduction — which most couples over 65 do.

QCD eligibility begins at age 70½ — you don't have to wait until RMDs begin at 73 or 75. This means a spouse who's 71 and charitably inclined can start QCDs even before their first mandatory distribution year, reducing the traditional IRA balance before RMDs begin.

QCD rules to know: The distribution must come directly from the IRA custodian to the charity — you can't take the money yourself and then donate it. A check made out to the charity, sent directly or via you, counts. QCDs cannot go to donor-advised funds (DAFs), private foundations, or supporting organizations; only to public charities. The $111,000 limit is per person per year and is indexed to inflation.²

IRMAA in the 70s: RMDs make it worse

By your 70s, IRMAA is no longer a risk to avoid — for many couples, it's a given to manage. RMDs are mandatory and add directly to MAGI. Social Security (likely both spouses now receiving) adds to MAGI. Investment income from a taxable portfolio adds. The question is which tier you're in and what tools you have to shift it.

The 2026 IRMAA tiers for married filing jointly, based on 2024 income:³

Note: surcharge amounts above reflect Part B only. Part D surcharges range from $14.50/month (Tier 1) to $91.00/month (Tier 5) per person — add approximately $348 to $2,184 per person per year. Table reflects CMS 2026 announcement. Two-year lookback: 2026 premiums are based on 2024 income.

The primary tools for IRMAA management in the 70s:

1. QCDs. As described above — reduces MAGI directly, unlike charitable deductions.
2. Roth conversions above the RMD. Counterintuitive: paying more tax now to reduce future RMDs shrinks MAGI in future years. A $500,000 traditional balance at 73 becomes a $630,000 balance by 78 at 6% growth, generating larger and larger RMDs. Converting $50,000–$80,000 per year above the RMD compresses future forced income.
3. Asset location review. If the taxable portfolio holds high-yield bonds generating ordinary income, consider whether those positions should be moved to IRAs (offset by holding more tax-efficient assets in taxable). Ordinary income from dividends and interest adds to MAGI; long-term gains from appreciated stock do not until sold.
4. IRMAA appeal (SSA-44). If your income dropped significantly — due to retirement, sale of a business, or a one-time distribution in a prior year — you can file SSA Form SSA-44 to appeal the IRMAA determination using your current, lower income. Qualifying life-changing events include retirement, divorce, and death of a spouse. Act promptly; IRMAA surcharges are applied based on prior-year income and require affirmative action to adjust.

Roth conversions in the 70s: still worth doing

Many couples assume Roth conversions are only for the 60s window before RMDs begin. That's wrong. Even after RMDs start, there's often a case for converting above your RMD if:

• Your pre-tax balance is still large. A $900,000 IRA at 73 generates a $33,962 RMD (at the 26.5 divisor). If you're in the 22% bracket and the IRMAA Tier 1 ceiling allows more income before crossing $218,000, converting an additional $50,000–$80,000 above the RMD can permanently reduce the future forced distribution burden — and the tax rates and Medicare costs that come with it.
• One spouse has a significantly larger pre-tax balance than the other. The heavier-balance spouse's RMDs will grow fastest. Systematic conversions from that account reduce the asymmetry and lower survivor-period IRMAA exposure (see below).
• You want to leave Roth assets to heirs. Non-spouse heirs who inherit a traditional IRA must take the full balance within 10 years and pay ordinary income tax on every dollar. A Roth IRA inherited by an adult child is also subject to the 10-year rule — but the distributions are tax-free. Paying tax on a conversion now at your bracket can save your heirs significantly more at their brackets.

One strict rule: you cannot convert your RMD itself to Roth. You must take the full RMD for the year before doing any conversion. The RMD comes first and must be taken as a distribution; only amounts above the RMD can be converted.

Capital gains harvesting: the window narrows but still exists

The 0% long-term capital gains rate applies to the first $98,900 of combined taxable income for MFJ in 2026.⁴ With RMDs, Social Security, and possibly pension income all contributing to taxable income, many couples in their 70s find the 0% bracket fully consumed or close to it.

But "narrow" doesn't mean "zero." If your combined taxable income — after the standard deduction — is $60,000 (RMDs + SS + investment income), you have $38,900 of room in the 0% capital gains bracket. Tax-gain harvesting (selling appreciated stock, rebuying it) permanently resets the cost basis at zero capital gains tax. The step-up in basis at death will reset it again for your heirs, but harvesting gains during your lifetime eliminates the tax on appreciation that happened while you were alive.

Harvesting gains in the 70s also makes tactical sense when:

• You're rebalancing a taxable portfolio that has drifted heavily toward equities after a bull run.
• You want to simplify holdings before estate transfer — selling a position with a $200,000 gain at 0% tax is far better than leaving a complex position for heirs to manage.
• One spouse is ill and the couple expects to file as a single filer soon — acting while MFJ brackets and thresholds apply can harvest gains that would otherwise be taxed at the narrower single-filer brackets.

The new senior deduction: $6,000 per person for ages 65+

Starting in 2025 (and running through 2028 under OBBBA), taxpayers age 65 or older can claim an additional $6,000 deduction per person.⁵ For a couple where both spouses are 65 or older, that's $12,000 in additional deductions on top of the regular standard deduction ($32,200 MFJ) and the existing per-person over-65 addition ($1,650 each, or $3,300 combined). Combined, a couple where both are over 65 can deduct up to $47,500 in 2026 if both qualify for the enhanced deduction.

The catch: the enhanced $6,000 senior deduction phases out above $75,000 of AGI for single filers and $150,000 for MFJ. For couples with significant RMD income, it may phase out partially or entirely. It's still worth calculating, especially early in the RMD decade when balances are lower and QCDs are reducing taxable income.

Social Security: what's still left to manage

For most couples in their 70s, Social Security claiming decisions are already made. But several SS-related issues remain active:

If either spouse hasn't claimed yet

While rare, some couples delay Social Security past 70 — there's no additional credit for waiting beyond 70, so claiming at 70 strictly dominates waiting longer. If either spouse is past 70 and hasn't claimed, claim immediately. Delayed claiming only makes sense up to age 70.

Survivor benefit planning

The surviving spouse receives 100% of the higher earner's benefit — and only that benefit (not both). If the higher earner has already claimed at 70, the survivor benefit is the higher of: the delayed benefit or 82.5% of the higher earner's FRA benefit (if the higher earner dies before 62 — complex edge case). For most couples, the survivor receives the higher earner's full delayed-to-70 benefit. Planning for this income level — and the tax implications when one benefit disappears — is discussed below.

Social Security taxation and the MAGI threshold

Up to 85% of Social Security benefits are taxable when combined income (AGI + half of SS benefits) exceeds $44,000 for MFJ filers.⁶ Most couples with significant RMD income are well above this threshold. Unlike IRMAA, there's no way to reduce SS benefit taxation directly — the 85% inclusion is baked in once you're above the threshold. QCDs reduce MAGI below the line, which is one more reason they're valuable.

The widower's financial trap: when one spouse dies

The death of a spouse triggers several simultaneous financial changes, and most surviving spouses are not prepared for how dramatically their tax situation deteriorates. A fee-only advisor can help a couple plan for this scenario before it happens — because the preparation (Roth conversions, account titling, beneficiary designations) must happen while both spouses are alive.

Tax filing status shift

The year of death: file as MFJ if the deceased died during the year (or married and living together for any part of the year). Years 1–2 after death: if the surviving spouse has a dependent child, they may file as Qualifying Surviving Spouse (QSS) with MFJ-equivalent brackets. Year 3 onward: single filer. For couples without dependent children, single-filer status begins immediately the year after death.

The bracket compression

Single filer brackets are roughly half the MFJ amounts. A surviving spouse with $100,000 in income who previously filed as MFJ in the 22% bracket may find that same income in the 24% bracket as a single filer. The income hasn't changed; the tax has.

IRMAA single-filer cliff

The IRMAA Tier 1 threshold for single filers is $109,000 — compared to $218,000 for MFJ. A surviving spouse with $130,000 in income (RMDs + Social Security) who was comfortably below the MFJ threshold is now $21,000 over the single-filer threshold. Medicare surcharges increase by roughly $1,949/year beginning two years after the death year.³

Estate portability: the 9-month deadline

The federal estate exemption in 2026 is $15M per person ($30M for a couple).⁷ If the first spouse to die doesn't use their full exemption, the surviving spouse can inherit the unused portion — called the Deceased Spousal Unused Exclusion (DSUE). To do this, the executor must file Form 706 within 9 months of death (or 15 months with an extension) specifically to elect portability, even if no estate tax is owed. Failing to file forfeits the DSUE permanently.

At $15M per person, federal estate tax is not a concern for most couples. But the portability election costs nothing to make and preserves maximum flexibility for the survivor's estate. File the 706 regardless of estate size.

Inherited IRA rules for the surviving spouse

A surviving spouse has unique options when inheriting an IRA — options no other beneficiary has:

• Spousal rollover (treat as own): The surviving spouse rolls the inherited IRA into their own IRA. RMDs are calculated based on their own age and the Uniform Lifetime Table. This is almost always the better choice for spouses who are younger than the deceased — they get lower RMDs under their own schedule.
• Beneficiary IRA (keep as inherited): The surviving spouse keeps the account as an inherited IRA. RMDs are calculated using the Single Life Table based on the survivor's age. This provides earlier penalty-free access if the survivor is under 59½ — useful in a small number of situations.
• Hybrid approach: Take some distributions as needed from the inherited IRA to avoid early-distribution penalties, then roll the remainder into the surviving spouse's own IRA after 59½.

Non-spouse beneficiaries (children, other heirs) who inherit a traditional IRA are subject to the 10-year rule: the full balance must be distributed within 10 years. If the deceased was past their required beginning date, annual RMDs are required during the 10-year period (T.D. 10001, July 2024).⁸ Roth IRA heirs face the same 10-year distribution window but no income tax.

Estate and beneficiary audit

Couples in their 70s should complete a full beneficiary and estate audit at least every 3 years and after any major life event (death of a named beneficiary, divorce of a child, birth of grandchildren). The key items:

• All retirement account beneficiary designations. These override your will. Verify primary and contingent beneficiaries on every IRA and 401(k). If an adult child is named as primary on both spouses' accounts, consider whether per-stirpes distribution makes sense for grandchildren if that child predeceases you.
• Life insurance. If term policies purchased decades ago are still in force, verify that beneficiaries are current. If the coverage was purchased to replace income — and both spouses are now living on fixed income from SS and investments — the need may have ended. Don't pay premiums on coverage you no longer need.
• POA and healthcare directive. Review who is named. Confirm the named agents are still the right people, are still living, and still have capacity. An outdated DPOA can be challenged if it names someone incapacitated or estranged.
• Trust review. If you have a revocable living trust, verify it was properly funded — assets must be titled in the trust's name to avoid probate. A trust that exists on paper but wasn't funded is an administrative shell.
• Egelhoff rule compliance. Beneficiary designations on plan accounts override divorce decrees. If either spouse was previously divorced, confirm that ex-spouse beneficiary designations have been removed from all accounts (IRAs, 401(k)s, and life insurance policies), not just changed in your will.

HSA spending in the 70s

If either spouse enrolled in Medicare Part A, they can no longer contribute to an HSA. But you can spend existing HSA balances tax-free on Medicare premiums (Part B, Part D, Medigap, Medicare Advantage — but not Medigap premiums if paid pre-tax through an employer plan), dental, vision, hearing, and all other qualified medical expenses.⁹

An HSA balance in the 70s is one of the most tax-efficient assets in the portfolio: it grows tax-free, distributes tax-free for medical expenses, and can also be used for non-medical expenses after age 65 (taxed as ordinary income, like a traditional IRA, but without any penalty). If your HSA balance is significant and your medical expenses are rising with age, now is when the account earns its purpose. Don't let it sit unused while paying Medicare premiums out-of-pocket.

Long-term care: managing what you have, not what you wish you had

By the 70s, most couples have either purchased LTC coverage or self-insured by default. New LTC insurance policies for couples in their 70s are expensive and often medically unavailable — underwriting standards preclude coverage for many applicants over 72. The planning discussion shifts from "should we buy coverage" to "how do we use what we have or manage what we don't."

If you purchased LTC coverage: review the policy today. Know the daily benefit amount, the elimination period (typically 90 days you pay out-of-pocket before benefits begin), whether you have an inflation rider, the maximum benefit period, and exactly how to file a claim. Many couples have policies purchased 10–15 years ago and don't know the details. The claim process can take weeks to navigate under stress — understanding it in advance is the preparation that actually matters.

If you're self-insuring: the average length of a long-term care event is 3 years, but the high-cost tail is 5–7 years.¹⁰ A couple self-insuring should estimate their reserve: $8,000–$12,000/month for assisted living, $10,000–$15,000/month for memory care, $25,000–$35,000/month for skilled nursing (varies significantly by region). Home equity, Roth balances, and taxable accounts are the typical self-insurance pool. Understand what the pool would look like if both spouses required care simultaneously.

What a fee-only advisor does for couples in their 70s

The conversations in the 70s are different from earlier decades. Less "how do we grow this?" and more "how do we distribute this efficiently and protect the surviving spouse?" A fee-only advisor working with couples in their 70s is typically doing:

• Annual IRMAA look-ahead: projecting next year's MAGI (RMDs + SS + capital gains + Roth conversions) and identifying if a tier boundary is at risk of being crossed.
• QCD vs. regular charitable giving optimization: ensuring charitable intent is executed in the most tax-efficient form.
• Roth conversion above RMD: determining whether the remaining traditional balance justifies continued conversions and at what amount.
• Survivor income modeling: projecting what the surviving spouse's income, taxes, and Medicare costs look like under different death timing scenarios — and identifying what to do now to improve those outcomes.
• Estate and beneficiary audit on a rolling 3-year cycle.

The financial issues of the 70s are not hard to understand — they're hard to coordinate. Two RMD schedules, two Medicare enrollments, two Social Security records, a taxable portfolio, and an estate plan that covers multiple scenarios all interact with each other in ways that benefit from a single professional seeing the whole picture.
