We’re mortgage-free: At 67 with a $100,000 income, should I start collecting $30,000 in Social Security or wait?

‘We own our home outright’: I am 67 and earn $100,000. Do I take my $30,000 Social Security now or wait?

If you’re 67, earning $100,000, and your Social Security benefit would be about $30,000 a year today, you’re right at a pivotal decision point. The short answer for many in your position: if you don’t need the income and expect average or better longevity, waiting—ideally to age 70—often pays meaningfully in lifetime, inflation-adjusted income and survivor protection. Here’s how to think it through.

What changes at 67
– You’re at or past full retirement age (FRA). For those born in 1960, FRA is 67; for 1959, it’s 66 and 10 months. Either way, the earnings test that withholds benefits for high earners no longer applies. You can keep working and collect benefits without penalty.
– Delayed retirement credits. For every month you delay after FRA, your benefit rises by about 0.67% (8% per year) until age 70. Credits stop at 70.

The key trade-off in plain numbers
– If your benefit is $30,000 at 67, waiting to 70 raises it by roughly 24% to about $37,200 per year, plus cost-of-living adjustments (COLAs).
– You forgo about $90,000 in payments between 67 and 70 in exchange for an extra ~$7,200 per year for life thereafter.
– Simple break-even (ignoring taxes and investment returns): $90,000 ÷ $7,200 ≈ 12.5 years. You come out ahead around age 82½. With taxes and the fact that much of today’s benefit would be taxed while you’re still working, the break-even can arrive sooner.

Taxes and Medicare considerations while working
– Income taxes: With $100,000 in wages, up to 85% of your Social Security would be taxable. That makes each dollar of benefit less valuable while you’re still employed.
– Medicare IRMAA: Medicare premiums are based on your modified adjusted gross income from two years prior. Adding Social Security now (up to 85% counted for IRMAA) could push a single filer over the first IRMAA threshold, increasing Part B and D premiums by hundreds to over a thousand dollars per year. Married couples filing jointly have higher thresholds, so this may be less of an issue.
– Bottom line: If you’re still earning $100,000, delaying Social Security can reduce current taxes and the risk of IRMAA surcharges while boosting your eventual benefit.

Longevity, inflation, and risk
– Social Security is a lifetime, inflation-adjusted annuity with no market risk. Delaying effectively “buys” more guaranteed income that keeps up with COLA.
– The value of delaying rises if you:
– Expect to live into your 80s or beyond (family history, good health).
– Prefer insurance against outliving assets or high late-life costs.
– Have a spouse who might outlive you (higher survivor benefit if you delay).

Spousal and survivor implications
– Survivor benefits: If you’re the higher earner, delaying increases what a surviving spouse will receive.
– Spousal benefits: A spouse cannot receive a spousal benefit on your record unless you’ve filed. If your spouse needs that spousal benefit now and cash flow matters, filing sooner can make sense.
– “Restricted application” and file-and-suspend strategies are largely gone for those your age; voluntary suspension after FRA is still allowed, but suspending stops any benefits paid off your record.

Working longer can help either way
– Continued earnings can replace lower-earning years in your 35-year Social Security calculation, slightly raising your benefit whether you claim now or later.
– If you do claim now, your check can be recomputed upward automatically if new earnings boost your record.

How being mortgage-free factors in
– With housing costs lower and less pressure on current cash flow, you’re well-positioned to delay without sacrificing lifestyle. That strengthens the case for waiting to 70.

When claiming now can still be right
– Health concerns or shortened life expectancy.
– You genuinely need the income to avoid high-interest debt or depleting savings too quickly.
– Your spouse needs a spousal benefit immediately and the household cash flow benefit outweighs the long-run gains from waiting.
– You plan to invest every dollar of today’s benefit at attractive, after-tax, risk-adjusted returns that you believe will exceed the value of the larger, guaranteed benefit later (a high bar).

A practical path forward
1. Verify your actual FRA and benefit amounts. Check your my Social Security account to confirm your Primary Insurance Amount (PIA), your benefit at 67, and the projected amount at 70.
2. Map the tax and Medicare picture. Estimate how claiming now would affect:
– Federal and state taxes (up to 85% of SS taxable).
– IRMAA exposure two years later (especially if single).
3. Consider retirement timing. If you expect to stop working before 70, you could:
– Delay Social Security until you retire, then reassess whether to file or keep delaying to 70.
– Use the years between retirement and claiming to manage taxes (for example, Roth conversions) without Social Security increasing your income.
4. Run a break-even and longevity stress test. Compare total lifetime income if claiming at 67 vs 70 under different lifespans (age 78, 82, 88, 92). Include taxes and any IRMAA impact.
5. Factor in your spouse. If married, compare outcomes for survivor benefits and whether spousal benefits now are material.
6. Keep flexibility. If you claim now and change your mind, you can:
– Within 12 months: withdraw the application, repay benefits, and reset as if you never filed.
– After FRA: voluntarily suspend to earn delayed credits until 70 (but any spousal/auxiliary benefits on your record also stop during suspension).

A simple recommendation for your facts
– You’re 67, earning $100,000, and you don’t have a mortgage. If you don’t need the income today and your health is average or better, waiting—ideally to age 70—will likely improve after-tax lifetime income, reduce near-term tax and Medicare frictions while you’re still working, and increase protection for a surviving spouse. If you plan to retire before 70, consider claiming then or still aiming for 70 depending on your cash flow and tax bracket in those years.

This is one of the most valuable levers you control in retirement planning. A one-hour session with a fee-only planner to model your tax, Medicare, and survivor outcomes can help you lock in the best choice with confidence.
