Overview
- Federal rules set the mechanics: people born in 1960 or later have a full retirement age of 67, benefits can start at 62 with up to a ~30% permanent cut, and delayed‑retirement credits of about 8% per year raise benefits until age 70.
- Many people in physically demanding jobs or with thin savings cannot wait for higher checks because poor health, lost pay and short COBRA or insurance gaps force earlier exits from work.
- Claiming timing has big tax and Medicare effects because up to 85% of benefits can be taxed, the taxable‑benefit thresholds have not been inflation‑adjusted since 1984, and prior‑year income can trigger IRMAA surcharges.
- Household choices matter: spousal and survivor rules can change the optimal filing age for couples and a key tactic older generations used — restricted applications for spousal benefits — is no longer available to most claimants.
- Because filing is largely irreversible, recent pieces urge modeling household scenarios, coordinating Roth conversions and withdrawals in low‑income years, and exploring SSDI or other bridge options when work ends early.
