Individuals aged 64 can begin claiming Social Security benefits before retirement, though doing so affects monthly payment amounts and federal tax obligations [1, 2].

Deciding when to claim is a critical financial pivot because early withdrawals permanently reduce the monthly benefit amount while potentially pushing retirees into higher tax brackets [2, 3].

According to the Social Security Administration, benefits are reduced by approximately five-ninths of 1% for each month claimed before the full retirement age, which equates to roughly 6.7% per year [2]. While the earliest eligibility age is 62, the full retirement age typically ranges between 66 and 67 depending on the birth year [2, 3].

Tax implications depend on a beneficiary's combined income. If combined income exceeds $34,000 for single filers or $44,000 for those married filing jointly, up to 85% of the benefits may be taxable [3]. To manage this, beneficiaries can elect a federal tax withholding rate of up to 10%, or they may choose 0% withholding [2].

Some financial professionals suggest that early claiming provides necessary cash-flow flexibility. One certified public accountant said, "I advise my clients to claim early because it gives them cash‑flow flexibility and they can still work while receiving benefits" [4].

However, other experts warn against the long-term cost. An MSN Money article said, "You can sign up for benefits at any time after you turn 62, but claiming before your full retirement age (FRA) carries real costs" [2].

Claimants must balance the immediate need for liquidity against the permanent reduction in monthly income. Those who continue to work while claiming early must also monitor their income levels to avoid unexpected tax liabilities at the end of the year [2, 4].

Claiming before your full retirement age (FRA) carries real costs.

The decision to claim Social Security at 64 represents a trade-off between current liquidity and future security. While early access provides immediate capital, the permanent reduction in the monthly benefit, combined with potential federal tax liabilities, can diminish a retiree's long-term purchasing power. This highlights the necessity of coordinating Social Security timing with other income sources to avoid crossing tax thresholds.
