Deciding when to claim Social Security is one of the most consequential financial decisions a retiree makes - and it is irreversible once made. The core tradeoff is simple: claim early and get smaller checks for longer, or delay and get larger checks for fewer years. The crossover point (breakeven) where delaying pays off is typically around age 82-84. Tax treatment of benefits, spousal strategy, and the earnings test for those still working add additional layers that change the optimal answer for each individual.
Age 62: Earliest eligibility. Benefit permanently reduced by up to 30% from your full retirement age (FRA) benefit.
Full Retirement Age (FRA): Age 67 for anyone born in 1960 or later. 100% of your earned benefit.
Age 70: Maximum benefit. Every year you delay past FRA adds 8% per year (delayed retirement credits). No benefit to waiting past 70.
| Birth Year | Full Retirement Age |
|---|---|
| 1943-1954 | 66 |
| 1955 | 66 and 2 months |
| 1956 | 66 and 4 months |
| 1957 | 66 and 6 months |
| 1958 | 66 and 8 months |
| 1959 | 66 and 10 months |
| 1960 and later | 67 |
Breakeven is the age at which the total lifetime benefits from delaying equal the total lifetime benefits from claiming early. Ignoring taxes and investment returns, the breakeven for waiting from 62 to 67 is roughly age 78-79. The breakeven for waiting from 67 to 70 is roughly age 82-83. If you expect to live past 83, delaying to 70 almost always maximizes lifetime benefits. If you have reason to believe your lifespan will be shorter - family history, current health - earlier claiming may produce a higher lifetime total.
If you claim Social Security before FRA and continue working, your benefits are reduced if your earnings exceed the annual exempt amount. For 2026, the exempt amount is approximately $22,320 (below FRA for the full year). For every $2 of earnings above the limit, SSA withholds $1 of benefits. In the year you reach FRA, the limit is higher and the withholding is $1 for every $3 above the limit. After you reach FRA, there is no earnings test - you can earn as much as you want with no reduction.
Withheld benefits are not truly lost - after FRA, SSA recalculates your benefit upward to credit you for months benefits were withheld. But the recalculation is slow and complex. Claiming early while still working is usually a poor strategy.
Social Security benefits are included in taxable income based on your "combined income" (AGI + nontaxable interest + half of Social Security benefits). The thresholds have not been indexed for inflation since 1984 and now affect most middle-income retirees:
| Combined Income (Single) | Combined Income (MFJ) | % of SS Benefits Taxable |
|---|---|---|
| Under $25,000 | Under $32,000 | 0% |
| $25,000 - $34,000 | $32,000 - $44,000 | Up to 50% |
| Over $34,000 | Over $44,000 | Up to 85% |
Note: "up to 85% taxable" is the maximum inclusion rate, not the tax rate. If 85% of your benefits are included in income, you still pay your marginal income tax rate on that 85%. For a retiree in the 22% bracket, the effective tax rate on Social Security is at most 18.7% (85% x 22%).
A spouse who earned little or no Social Security credits can claim up to 50% of the higher-earning spouse's FRA benefit. The spousal benefit is reduced if claimed before the claiming spouse's own FRA. Importantly, the spousal benefit does not grow past FRA - no delayed retirement credits accrue on the spousal benefit. A lower-earning spouse should generally claim at or near FRA while the higher earner delays to 70.
Survivor benefit: When one spouse dies, the survivor receives the higher of the two benefit amounts. This makes it especially valuable for the higher-earning spouse to delay to 70 - the delayed, larger benefit becomes the survivor benefit that supports the remaining spouse potentially for decades. This is often the most important variable in the claiming decision for married couples.
