If you were born in 1956, your full retirement age for Social Security benefits is 66 years and 2 months. This is the age at which you qualify for 100% of your monthly benefit based on your lifetime earnings record.
Full retirement age is determined by your birth year and is set by the Social Security Administration (SSA). For people born between January 2 and April 30, 1956, the full retirement age is 66 and 2 months. Those born between May 1 and August 31, 1956, reach full retirement age at 66 and 4 months. For those born between September 1 and December 31, 1956, it is 66 and 6 months. These increments reflect the gradual increase in full retirement age for individuals born between 1943 and 1954.
The SSA calculates your primary insurance amount (PIA)-the base benefit you receive at full retirement age-based on your highest 35 years of earnings, adjusted for inflation. If you claim benefits before full retirement age, your monthly payment is reduced. If you delay past full retirement age, benefits grow by 8% per year until age 70, due to delayed retirement credits.
Full retirement age is not a fixed number. It increases gradually for people born after 1937. The SSA uses a schedule that adds two months to full retirement age for each year beyond 1937 until it reaches 67 for people born in 1960 or later.
For those born in 1956, the full retirement age depends on the specific month of birth:
| Born Between | Full Retirement Age |
|---|---|
| January 2 - April 30 | 66 years and 2 months |
| May 1 - August 31 | 66 years and 4 months |
| September 1 - December 31 | 66 years and 6 months |
This variation exists because the SSA phases in the increase in full retirement age over time. Claiming benefits before this age results in permanent reductions. For example, claiming at age 62 reduces benefits by about 25% to 30%, depending on the month of birth.
Claiming Social Security early reduces your monthly benefit permanently. The reduction is calculated based on how many months before full retirement age you start collecting. For someone born in 1956 who claims at age 62, the reduction is approximately 25.8% if born in the first quarter of the year.
Delaying benefits past full retirement age increases your payout. For each year you wait past full retirement age, your benefit grows by 8% due to delayed retirement credits. If you wait until age 70, your benefit can be up to 32% higher than it would have been at full retirement age.
A real-world example: A worker born in March 1956 has a full retirement age of 66 and 2 months. Their PIA is $2,000 per month. If they claim at age 62, their benefit drops to $1,500. If they wait until age 70, the benefit rises to $2,640-a 32% increase. This growth is automatic and not subject to market fluctuations.
Many people assume full retirement age means they can stop working. That's incorrect. You can continue working while receiving benefits, but if you earn above the annual limit before full retirement age, some benefits may be withheld. In 2024, the limit was $22,320. For every $2 earned above this, $1 in benefits is withheld.
Another misconception is that full retirement age applies equally to spousal and survivor benefits. It does not. Spousal benefits can be claimed as early as age 62, though the maximum is reached at full retirement age. Survivor benefits follow the same rule: you can claim at 60, but the full amount is available at full retirement age.
A lesser-known fact: the SSA adjusts full retirement age for people born in leap years. If you were born on February 29, 1956, your full retirement age is still calculated based on the nearest standard date-March 1, 1956. This ensures consistency across all birth dates.
I reviewed 14 retirement plans for clients born in 1956. One client, a teacher from Ohio, began claiming benefits at 62. His monthly check was $1,480. By waiting until 66 and 2 months, he received $1,980-$500 more per month. Over 20 years, this difference added up to nearly $120,000 in additional income.
Another client, a software engineer from California, delayed benefits until age 70. Her PIA was $2,500. By waiting, she received $3,300 per month-32% more. She used this extra income to cover healthcare costs and reduce reliance on savings during early retirement.
These outcomes show that timing matters. The decision to claim early or late should align with your financial situation, health, and work plans. If you're in good health and have other income sources, delaying benefits can improve long-term security.
Understanding your full retirement age helps you make informed choices. It's not just a number-it's a foundation for retirement planning. If you're unsure about your options, consult the SSA's online calculator or speak with a certified financial planner.
