Why timing and spousal benefits matter

Social Security is designed as an insurance-and-income program. For married couples, claiming decisions aren’t independent: when one spouse files affects the options and potential income available to the other. A purposeful timing strategy can increase joint lifetime benefits, protect the lower-earning spouse, and improve survivor benefit outcomes if one spouse dies first.

In my practice as a CPA and CFP®, I commonly see couples claim benefits early without running simple scenarios — and lose tens of thousands of dollars over a joint lifetime. This article explains the rules that govern spousal benefits, practical strategies, key tradeoffs, and next steps you can use to test options for your household.

Spousal benefit basics (quick primer)

  • Eligibility: A spouse generally qualifies for a spousal benefit if the marriage lasted at least one year and the worker is eligible for Social Security retirement benefits. A divorced spouse can qualify if the marriage lasted at least 10 years and the claimant is unmarried.
  • Amount: The spousal benefit can be up to 50% of the worker’s Primary Insurance Amount (PIA) at the spouse’s Full Retirement Age (FRA). If claimed before FRA, the spousal benefit is reduced.
  • Interaction: A spouse who is eligible for their own worker benefit will receive whichever amount is higher — their own benefit or the spousal benefit (not both).
  • Survivor benefits: When one spouse dies, the surviving spouse can often receive up to the deceased worker’s benefit amount (subject to eligibility and age rules).

Core rules that drive optimization

  1. Delayed retirement credits: For those born in 1943 or later, every year you delay past FRA up to age 70 increases your benefit by about 8% per year (these are delayed retirement credits). Delaying increases both the higher earner’s benefit and the potential spousal/survivor amounts tied to that earnings record.

  2. Full Retirement Age (FRA): FRA depends on birth year (typically age 66–67 for most current retirees). Spousal payments are based on the worker’s PIA measured at the worker’s FRA.

  3. Earnings test and reductions: If you claim before FRA and continue to work, benefit payments may be reduced by the SSA’s earnings test until you reach FRA. Those withheld amounts are converted into higher benefits at FRA, but the timing and cash flow impact matter.

  4. Survivor math: The larger the higher-earning spouse’s benefit at death, the larger the survivor benefit. Maximizing the higher earner’s benefit (by delaying to 70) often protects the surviving spouse’s standard of living.

  5. Taxation: Combined household income can make a portion of Social Security benefits taxable. Claim timing interacts with taxable income and required minimum distributions (RMDs) from retirement accounts, so coordinate with tax and cash-flow planning.

Practical strategies for couples

  1. Identify the higher earner and treat their record as the primary lever.
  • If one spouse has a substantially higher PIA, delaying that spouse’s claim to 70 often raises the survivor benefit and increases the spousal maximum. In my experience, this is the most effective lever for many couples.
  1. Consider a split-claiming approach only when it’s allowed.
  • Note: Restricted application for spousal benefits (filing just for spousal benefit while letting your own benefit grow) was largely eliminated for new claimants born after January 2, 1954. Check your eligibility before assuming a restricted application is available. (SSA site)
  1. Use filing timing to protect the lower earner’s cash flow.
  • If the lower earner needs income early, they might claim at 62 while the higher earner delays. But be careful: an early claimant’s benefit is permanently lower and could be smaller than a spousal benefit available later.
  1. Delay the higher earner when longevity and portfolio planning support it.
  • If both spouses are healthy and the couple has other income sources for the 60s, delaying the higher earner to 70 often maximizes joint lifetime benefits and survivor protection.
  1. Run break-even and life-expectancy scenarios.
  • Break-even analysis compares cumulative benefits if you claim early vs. delay and depends on assumed life spans and discounting. In practice, run multiple scenarios (e.g., one spouse to age 85, 90, 95) to see which filing ages maximize joint lifetime income.
  1. Factor in taxes and Medicare costs.
  • Claiming early increases taxable Social Security exposure in years when other taxable income (pensions, wages, Roth withdrawals) exists. Coordinate claiming with tax planning to avoid unexpected taxable thresholds.
  1. Don’t forget divorced-spouse and survivor rules.
  • A divorced spouse who meets the 10-year marriage rule can claim spousal benefits based on an ex’s record even if the ex has remarried. Survivor benefits can change the calculus dramatically: if a higher-earning spouse dies early, a survivor who had a protected larger benefit will be better positioned.

Realistic example (illustrative)

Consider a couple where Partner A’s PIA at FRA is $3,000 and Partner B’s own PIA is $900. If A delays to 70, A’s benefit grows to about $3,720 (8% per year × three years beyond FRA — illustrative). B’s spousal benefit at FRA could be up to 50% of A’s PIA (about $1,500 at FRA), though actual amounts depend on B’s claiming age and whether B claimed early.

If A claims at 62, both A’s own benefit and potential survivor benefit are permanently lower. Over a couple’s joint life, delaying A can often produce higher cumulative payments and better survivor support for B, especially if B has limited work history.

Note: These numbers are illustrative. Run personalized estimates using the SSA calculators and your actual statements.

Common mistakes I see

  • Treating Social Security as an individual decision rather than a household decision.
  • Assuming the highest initial monthly check equals the best lifetime outcome.
  • Failing to confirm eligibility for restricted applications or divorced-spouse rules before making decisions.
  • Ignoring tax interactions and the earnings test when claiming before FRA.

Action checklist (what to do next)

  1. Pull recent Social Security statements for both spouses (create an SSA account at ssa.gov if you don’t have one). (SSA: Retirement Planner)
  2. Identify each spouse’s PIA and FRA, and note any pensions or earned income that may affect taxes or the earnings test.
  3. Run multiple claiming scenarios: (a) both claim early, (b) one delays to 70 while the other claims early, (c) both delay to FRA or 70. Compare joint lifetime totals under different longevity assumptions.
  4. Consult a fee-only financial planner or tax advisor to model tax impacts and coordinate distributions from retirement accounts with Social Security timing.
  5. Revisit your plan annually or when major life changes occur (health, job, divorce, or death).
