Retirement income planning
When to Take Social Security: 62, 67, or 70?
Claim at 62 and your monthly check shrinks by roughly 30 percent for life. Wait until 70 and it grows by roughly 24 percent over your full retirement age amount. The gap between the earliest and latest claim can easily top $1,000 a month, every month, for the rest of your life. So which is right? It depends on your health, your taxes, your spouse, and what those in-between years could otherwise do for your Roth conversions.

The short version
- The tradeoff: with a full retirement age of 67, claiming at 62 pays about 70% of your full benefit for life; waiting until 70 pays about 124%.
- Breakeven: 62 vs. 67 breaks even around age 78; 67 vs. 70 breaks even around 82 or 83. Outlive those ages and waiting wins.
- Taxes: benefits become taxable based on provisional income, with thresholds ($25k single, $32k joint) that have never been indexed for inflation.
- Spouses: spousal benefits pay up to 50% of the worker's benefit; survivor benefits can reach 100%, which makes the higher earner's delay especially valuable.
- The hidden cost of claiming early: benefit income in your 60s fills up low tax brackets that Roth conversions could have used instead.
What claiming early or late actually pays
Your benefit is calculated from your 35 highest-earning years, adjusted for wage inflation. That produces your primary insurance amount (PIA), which is what you receive if you claim at exactly your full retirement age (FRA). For anyone born in 1960 or later, FRA is 67. Claim earlier or later and the monthly amount is adjusted permanently:
| Claiming age | Monthly benefit (vs. FRA) | On a $2,000 FRA benefit |
|---|---|---|
| 62 (earliest) | About 70% | $1,400 |
| 67 (full retirement age) | 100% | $2,000 |
| 70 (latest) | About 124% | $2,480 |
Claiming at 62 with an FRA of 67 means a 30% haircut: 20% for the first 36 months early, plus 10% for the next 24. Delaying past FRA earns delayed retirement credits of 8% per year until 70. There is no benefit to waiting past 70. Cost-of-living adjustments (2.8% for 2026) apply on top of whichever base you lock in, so delaying also compounds against a larger number.
The breakeven age, and why it is not the whole story
Breakeven analysis asks a simple question: at what age do total lifetime benefits from claiming later overtake total benefits from claiming earlier? The rough answers:
- 62 vs. 67: breakeven lands around age 78.
- 67 vs. 70: breakeven lands around age 82 to 83.
If you live well past those ages, waiting pays more in total. Die earlier and claiming early wins. The problem is that breakeven math pretends this is the only question, and it ignores three things that often matter more:
- Taxes. Benefit income interacts with IRA withdrawals, capital gains, and Medicare premiums. A dollar of Social Security is not taxed the same as a dollar of IRA withdrawal.
- Your spouse. Breakeven for a single person and breakeven for a couple are different calculations, because survivor benefits extend the payoff of delaying.
- What the money does meanwhile. Claiming early means withdrawing less from your portfolio; delaying means drawing the portfolio down faster in your 60s. Which is better depends on your balances and tax brackets.
Your health and family longevity history deserve more weight than the breakeven spreadsheet. Someone in excellent health with long-lived parents is making a very different bet than someone with a serious diagnosis.
How Social Security gets taxed
Whether your benefits are taxed depends on "provisional income": your adjusted gross income (excluding benefits), plus any tax-exempt interest, plus half of your Social Security benefits. The thresholds:
| Filing status | Provisional income | Taxable share of benefits |
|---|---|---|
| Single | Under $25,000 | None |
| Single | $25,000 to $34,000 | Up to 50% |
| Single | Over $34,000 | Up to 85% |
| Married filing jointly | Under $32,000 | None |
| Married filing jointly | $32,000 to $44,000 | Up to 50% |
| Married filing jointly | Over $44,000 | Up to 85% |
Two things make this nastier than it looks. First, these thresholds were set in 1984 and 1993 and have never been indexed for inflation, so every COLA and every raise pushes more retirees over them. Second, there is the "tax torpedo": in the phase-in ranges, an extra $1,000 of IRA withdrawal can make an additional $850 of Social Security taxable too, so that $1,000 withdrawal adds $1,850 to your taxable income. One new softener: for tax years 2025 through 2028, filers 65 and older get an extra $6,000 senior deduction, which shrinks the income these thresholds are measured against.
Spousal and survivor benefits
If you are married, the claiming decision is a joint one:
- Spousal benefits pay up to 50% of the higher earner's full retirement age benefit, reduced if the spouse claims before their own FRA. A spouse with little or no earnings history still qualifies.
- Survivor benefits pay up to 100% of what the deceased worker was receiving (or entitled to). This is why the higher earner's delay is the most valuable move a couple can make: delaying to 70 permanently raises the surviving spouse's income for the rest of their life.
The common optimal pattern for couples: the lower earner claims earlier to bring income in, while the higher earner delays to 70 to maximize the survivor benefit. It is longevity insurance for whoever lives longest.
The gap years: claiming early vs. Roth conversions
Here is the tradeoff most articles skip. The years between retirement and age 70 are usually the best Roth conversion window of your life: no paycheck, no RMDs yet, and (if you manage it) no Social Security. Every dollar of Social Security you collect in those years fills up low tax brackets at ordinary rates, brackets that could otherwise have been filled with Roth conversions at 10 or 12%.
Run the comparison honestly. Claiming at 62 might pay you $1,400 a month, but if it displaces $16,800 a year of Roth conversions that would have saved 10+ percentage points of tax later, the "extra" income is partly an illusion. On the other hand, if you have little traditional IRA balance to convert, or you need the cash flow to avoid selling investments in a down market, claiming earlier can be the right call. This is a year-by-year optimization problem, which is exactly what a tax-aware planner is for.
When claiming early makes sense
- Health is poor or family longevity is short. Bird in the hand.
- You need the money to avoid high-interest debt or selling portfolio assets at bad prices.
- You are single with no survivor concerns and the breakeven math is genuinely unfavorable.
- You are still working past 62 is actually a reason to wait, not claim (see the earnings test above).
When waiting usually wins
- You are healthy with long-lived relatives. Longevity is the single best predictor that delaying pays.
- You are the higher earner in a couple. Your delay is your spouse's survivor benefit.
- You are doing Roth conversions in your 60s and want low-bracket room for them.
- You can fund the gap years from taxable savings or part-time work without stress.

What is my full retirement age?
It is 67 if you were born in 1960 or later, and 66 years and 10 months if you were born in 1959. Claim at exactly that age and you receive 100% of your calculated benefit (your primary insurance amount).
Is Social Security going to run out?
No, but benefits could be reduced. The 2026 Trustees Report projects the retirement trust fund's reserves run short in late 2032; after that, incoming payroll taxes would cover roughly 78% of scheduled benefits unless Congress changes the law. Planning your retirement on 75 to 80% of promised benefits is a reasonable stress test.
Can I change my mind after claiming Social Security?
Within 12 months of starting benefits, you can withdraw your application one time, repay everything you received, and reset the clock as if you never claimed. After reaching full retirement age, you can also voluntarily suspend benefits and earn delayed retirement credits until 70.
Does my claiming age affect my spouse's survivor benefit?
Yes, directly. A surviving spouse can receive up to 100% of the deceased worker's benefit amount, so when the higher earner delays to 70, the survivor benefit is permanently larger. For couples, this is often the strongest argument for delaying.
Will I pay tax on my Social Security benefits?
It depends on your provisional income: AGI plus tax-exempt interest plus half your benefits. Below $25,000 (single) or $32,000 (joint), benefits are not taxed. Above $34,000 single or $44,000 joint, up to 85% of benefits becomes taxable. These thresholds are not indexed for inflation.
Should both spouses delay Social Security to 70?
Not necessarily. The highest-value delay is the higher earner's, because it sets the survivor benefit. The lower earner claiming at 62 or at FRA can provide useful income while the higher earner's benefit keeps growing at 8% per year.
