Social Security retirement benefits kick in the month after the start month you choose on your application, and you can pick any month from age 62 through age 70. Age 62 is the earliest, but claiming then locks in a permanently reduced payment. Your full retirement age — somewhere between 66 and 67, depending on the year you were born — is the point at which you get 100 percent of your calculated benefit. Waiting past that adds credits until you hit 70, where the increases stop.
The Earliest You Can Claim Is 62
You can file for retirement benefits as soon as you reach 62, provided you have enough work history to qualify. Filing that early comes at a cost. The Social Security Administration reduces your benefit by five-ninths of one percent for each of the first 36 months you claim before your full retirement age, and by five-twelfths of one percent for each additional month beyond that.1Social Security Administration. Benefit Reduction for Early Retirement
For someone whose full retirement age is 67, claiming at 62 means filing 60 months early, which produces a 30 percent reduction from the full benefit amount.2Social Security Administration. Benefits Planner: Retirement Age and Benefit Reduction That reduction is permanent. It becomes the base your future cost-of-living adjustments are calculated from.
Full Retirement Age by Birth Year
Full retirement age (FRA) is the point at which you qualify for your full calculated benefit with no reduction and no bonus. It has drifted upward over the decades and now depends entirely on when you were born.3eCFR. 20 CFR 404.409 – What Is Full Retirement Age?
- Born 1943–1954: FRA is 66.
- Born 1955: FRA is 66 and 2 months.
- Born 1956: FRA is 66 and 4 months.
- Born 1957: FRA is 66 and 6 months.
- Born 1958: FRA is 66 and 8 months.
- Born 1959: FRA is 66 and 10 months.
- Born 1960 or later: FRA is 67.
One quirk: if your birthday falls on January 1, the SSA treats you as if you were born the prior year. Someone born January 1, 1960, has an FRA of 66 and 10 months, not 67.4Social Security Administration. Retirement Benefits
Waiting Past FRA Boosts Your Payment Until Age 70
Delaying past your full retirement age earns delayed retirement credits worth two-thirds of one percent per month, or 8 percent per full year. Those credits stop accumulating at 70, so there is no financial reason to wait longer.5Social Security Administration. Delayed Retirement Credits
For someone with an FRA of 67, waiting until 70 produces a monthly payment equal to 124 percent of the full benefit. Whatever amount you lock in becomes the base for future cost-of-living adjustments. The 2026 COLA, for example, is 2.8 percent and applies to every beneficiary regardless of when they claimed.6Social Security Administration.

Age Alone Doesn’t Qualify You — You Need 40 Work Credits
Reaching 62 is only half of what it takes. To collect retirement benefits, you must also be “fully insured,” which under federal law generally means 40 quarters of coverage.7Office of the Law Revision Counsel. 42 US Code 414 – Insured Status for Purposes of Old-Age and Survivors Insurance Benefits You can earn up to four credits per year, so the minimum is roughly ten years of covered work.8Office of the Law Revision Counsel. 42 USC 402 – Old-Age and Survivors Insurance Benefit Payments
In 2026, you earn one credit for every $1,890 in covered earnings, so it takes $7,560 in annual earnings to collect all four credits for the year.9Social Security Administration. Quarter of Coverage Once you hit 40 credits, you stay insured for retirement purposes even if you never work another day.
How to Apply and When Your First Check Arrives
Nothing happens automatically at 62, 67, or 70. You have to file an application. The SSA recommends applying up to four months before you want your first payment to arrive, and you can apply online, by phone, or at a local field office.10Social Security Administration. How Do I Apply for Social Security Retirement Benefits?
You will need to provide:
- Your Social Security number.
- Proof of age — an original birth certificate or a certified copy from the issuing agency. Photocopies and notarized copies are not accepted.
- Citizenship or immigration documents if you were not born in the United States.
- Discharge papers if you served in the military before 1968.
- Your most recent W-2 or self-employment tax return.
The SSA advises applying even if you are missing a document, because waiting can cost you benefits you are owed.11Social Security Administration. What Documents Do You Need to Apply for Retirement Benefits? Payments must go out electronically, either through direct deposit or a Direct Express debit card, with only rare Treasury exceptions.12Social Security Administration. Direct Deposit
Your First Payment Comes the Month After Your Start Month
On your application you pick a start month. Your first payment arrives the following month, because Social Security pays in arrears — the check you receive in any given month covers the prior month’s benefit.13Social Security Administration. Timing Your First Payment Pick January as your start month, and your first deposit lands in February.
The specific day of the month depends on your birthday:14Social Security Administration. Schedule of Social Security Benefit Payments 2026-2027
- Born on the 1st–10th: second Wednesday of the month.
- Born on the 11th–20th: third Wednesday of the month.
- Born on the 21st–31st: fourth Wednesday of the month.
Two exceptions apply. If you first became entitled to Social Security before May 1997, or you also receive Supplemental Security Income, your payment comes on the 3rd of the month instead of a Wednesday.15Social Security Administration. Code of Federal Regulations 404.1807 – Monthly Payment Day When a scheduled date falls on a weekend or federal holiday, the SSA sends the payment on the preceding business day.
Retroactive Payments If You’re Past FRA and Haven’t Filed
If you have already passed your full retirement age and never filed, the SSA can pay you up to six months of retroactive benefits when you apply. Retroactive payments cannot cover any month before you reached FRA.5Social Security Administration. Delayed Retirement Credits
Taking retroactive benefits lowers your ongoing monthly amount, because the SSA treats your start date as the earlier month. Someone who files at 68 and requests six months of back pay has their monthly benefit calculated as though they started at 67 and a half.
Medicare Doesn’t Wait for Your Social Security Decision
If you are already receiving Social Security when you turn 65, the SSA enrolls you automatically in Medicare Part A and Part B. Coverage begins the month you turn 65, or the prior month if your birthday is on the first.16Social Security Administration. Medicare
If you have delayed your Social Security claim past 65, you have to sign up for Medicare yourself. Your initial enrollment period runs from three months before the month you turn 65 through three months after it — a seven-month window.17Medicare. When Can I Sign Up for Medicare Missing it can trigger a late-enrollment penalty that permanently raises your Part B premium, so keep the Medicare date on the calendar even if your Social Security date is years away.
