Social Security Timing: Getting It Right for You

Quick Takeaways

  • You can file as early as 62 or wait until 70; after your Full Retirement Age (FRA, ~66–67 by birth year), benefits grow roughly 8% per year until 70.
  • Claiming earlier can reduce the need to sell investments during downturns.
  • Claiming later can improve lifetime after-tax income and create a larger, more secure base – especially for the higher earner in a couple.
  • The “right” answer depends on health, longevity, cash-flow needs, taxes, and spousal coordination. Not just the biggest monthly check.

1) Start with the math

  • Before FRA → reduced monthly benefit.
  • After FRA → delayed credits (~8%/yr) up to age 70.

Think in lifetime dollars, not just the monthly check: bigger checks later = fewer total checks; smaller checks earlier = more months paid.

Rule of thumb: If you expect average or better longevity and don’t need the income today, waiting often wins. If health is uncertain or cash flow is tight, earlier can be prudent.

2) Portfolio risk: why earlier can help

The first 5–10 years of retirement are most vulnerable to sequence-of-returns risk. If markets fall while you’re drawing from the portfolio, you may lock in losses.

Starting Social Security earlier can:

  • Reduce withdrawals during a downturn,
  • Keep more shares invested for a recovery,
  • Provide a steady “paycheck” that helps you stick to the plan.

3) Taxes: why later can help

Up to 85% of benefits can be taxable depending on combined income (AGI + nontaxable interest + ½ of benefits). Delaying can open a tax “window” in your 60s to:

  • Draw from IRAs/401(k)s or do Roth conversions at lower brackets,
  • Shrink future RMDs,
  • Potentially reduce how much of Social Security is taxed once you do claim.

4) Spouses & survivors: coordinate on purpose

  • A surviving spouse generally keeps the higher benefit.
  • Often, the higher earner delaying (even to 70) maximizes the survivor benefit; the lower earner can file earlier if cash is needed.
  • Consider ages, health, and who would be most impacted financially.

5) Personal levers that tip the decision

  • Health & family longevity: shorter outlook → earlier; strong longevity → later.
  • Working before FRA: the earnings test may temporarily reduce benefits (with make-up later).
  • Cash reserves: more savings = more flexibility to delay; thin margins may argue for earlier.

Common playbooks we see:

  1. Safety-first (62–65): Minimize portfolio withdrawals and sleep at night. This is useful if health is uncertain.
  2. Middle path (at FRA): Start once the earnings test ends and avoid the full early-claim haircut.
  3. Max longevity insurance (wait to 70): Larger inflation-adjusted base for life (and survivor), with room for pre-claim tax moves.
