Retirement planning for couples is fundamentally different from planning for individuals. You're coordinating two Social Security claiming strategies, two sets of retirement accounts, potentially different retirement dates, and a survivor scenario that will eventually leave one spouse managing everything alone. The decisions you make together can mean a difference of $200,000+ in lifetime income — but most couples plan in silos.

Key Takeaway

The most impactful decision for most couples is Social Security coordination: the higher earner should almost always delay to 70 (increasing the survivor benefit by up to 76%), while the lower earner may claim earlier to bridge the income gap. This single decision can be worth $100,000-$200,000 in lifetime household income.

Why Couples Planning Is Different

Individual retirement planning asks: "Will I have enough?" Couples planning asks a much more complex set of questions:

  • When should each spouse retire? — Different ages, different savings, different career trajectories
  • How do we coordinate Social Security? — Four possible claiming ages to optimize
  • What happens when one spouse dies? — The survivor keeps the higher benefit but loses the lower one, and moves to single-filer tax brackets
  • Whose accounts should we draw from first? — Tax-efficient withdrawal order gets more complex with two sets of accounts
  • How do we handle the age gap? — A 3-5 year age difference changes Medicare timing, RMD timing, and Social Security optimization

Social Security: The Biggest Decision

For most couples, Social Security coordination is the single highest-value planning decision. The key principles:

The Higher Earner Should Delay to 70

When one spouse dies, the surviving spouse keeps the higher of the two Social Security benefits. The lower benefit disappears entirely. By having the higher earner delay to 70, you're maximizing the survivor benefit — which could support the surviving spouse for 10-20+ years.

  • At 62: Higher earner gets 70% of PIA
  • At 67 (FRA): 100% of PIA
  • At 70: 124% of PIA — this becomes the survivor benefit

The difference between the survivor receiving 70% vs. 124% of PIA can easily be $1,000-$1,500/month — or $180,000-$270,000 over 15 years of widowhood.

The Lower Earner Can Claim Earlier

If the higher earner is delaying to 70, the lower earner may benefit from claiming earlier (62-67) to provide household income during the delay period. The lower earner's benefit has less impact on the survivor benefit (which is based on the higher benefit), so the cost of claiming early is smaller.

Important Consideration

If you were previously married for 10+ years before divorcing, you may qualify for divorced spouse benefits on your ex's record — which could be higher than your own benefit. This doesn't affect your current spouse's benefits at all.

The Survivor Scenario: Planning for One

Every couple will eventually become a single-person household. The financial impact is severe and often underestimated:

Income Drops, Expenses Don't

  • Social Security: The household goes from two checks to one (the higher benefit). Income drops by 33-50%.
  • Expenses: Housing, utilities, insurance, and property taxes don't change. Food and some discretionary costs drop, but total expenses typically only fall 20-30%.
  • Tax brackets: The survivor moves from "married filing jointly" to "single" — which means higher tax rates on the same income. This is the "widow's tax penalty."

How to Protect the Survivor

  • Maximize the higher earner's Social Security (delay to 70)
  • Build Roth balances — Roth withdrawals don't count as income, helping the survivor manage the widow's tax penalty
  • Consider life insurance for the higher earner if the income gap is large
  • Model the scenario explicitly — Don't just plan for "both alive." Model what happens at year 5, 10, and 15 after one spouse dies.

Coordinating Retirement Dates

Couples often retire at different times. A common pattern: one spouse retires at 60-62 while the other works until 65-67. This creates planning opportunities and challenges:

The Bridge Period

When one spouse retires early:

  • Health insurance: The retired spouse may go on the working spouse's employer plan (cheapest option) until Medicare at 65
  • Income gap: The household has one salary instead of two. Draw from savings or have the retired spouse do part-time work.
  • Roth conversion opportunity: If the retired spouse has low individual income, this may be an ideal window for Roth conversions in lower brackets

Both Retire at the Same Time

If both spouses retire simultaneously:

  • Household income drops to zero earned income immediately — budget for this
  • Both may need individual health insurance if under 65 (expensive)
  • The upside: larger Roth conversion window since household income is very low

Tax Planning as a Couple

The Married Filing Jointly Advantage

Married couples filing jointly get wider tax brackets than single filers. For example, in 2026 the 12% bracket extends to ~$96,950 for joint filers vs. ~$48,475 for single. This means couples can withdraw nearly twice as much from tax-deferred accounts before hitting the 22% bracket.

Use this advantage while both spouses are alive: do Roth conversions that fill the 12% or 22% brackets, and manage your withdrawal order to stay in favorable brackets.

RMD Coordination

If both spouses have traditional IRAs/401(k)s, both will face RMDs starting at 73-75. Combined RMDs can push the couple into higher brackets. Strategies:

  • Convert before RMDs start — Reduce the tax-deferred balance that drives RMDs
  • Stagger drawdowns — If one spouse is younger, focus conversions on the older spouse's accounts first (RMDs start sooner)
  • Use the Roth — For spending needs above what RMDs provide, use Roth withdrawals to avoid adding to taxable income

Common Mistakes Couples Make

  1. Both claim Social Security at the same age — Couples often default to "we'll both claim at 62" or "we'll both wait." The optimal strategy almost always involves different claiming ages for each spouse.
  2. Ignoring the survivor scenario — Planning only for "both alive" and never modeling what happens when one spouse dies leads to nasty surprises for the survivor.
  3. Not coordinating accounts — Each spouse manages their own 401(k) and IRA independently, missing opportunities for tax-efficient coordination across all accounts.
  4. Underestimating the widow's tax penalty — The jump from married filing jointly to single filer can increase effective tax rates by 5-10 percentage points on the same income.

Using Bullseye for Couples Planning

Bullseye is designed for couples planning from the ground up:

  • Separate profiles for each spouse — Track different ages, retirement dates, Social Security benefits, and account balances for both spouses
  • Combined tax modeling — Bullseye calculates your joint federal and state taxes based on combined income from all sources
  • Social Security optimization — Model different claiming ages for each spouse and see the impact on lifetime household income
  • Survivor scenarios — Use Bullseye's Scenarios feature to model what happens to household finances if one spouse passes at different ages
  • IRMAA tracking — See how combined income affects Medicare surcharges for both spouses

Bottom Line

Couples have more planning levers than individuals — but also more ways to leave money on the table. The highest-impact decisions are: (1) coordinate Social Security claiming to maximize the survivor benefit, (2) plan explicitly for the survivor scenario, (3) use the wider married filing jointly brackets for Roth conversions and withdrawal optimization, and (4) model both spouses' accounts as one coordinated plan. Start by running your combined projection in Bullseye and testing different Social Security claiming combinations.
