A clear look at your Social Security full retirement age dates

If you were born in 1960 or later, your full retirement age is 67. That is the whole answer to the question most people arrive with, and no chart is going to change it.

Where you go from here depends on your situation:

• Born 1960 or later — your age is 67. What matters on this page is what that date decides, not the date itself.
• Born 1955 through 1959 — you have a row of your own, somewhere between 66 and 2 months and 66 and 10 months.
• Born 1954 or earlier — your date has already passed. Section four covers back payments.
• Claiming as a widow or widower — you may have a second, earlier date. Section six.
• Still working — a third date governs when your wages stop reducing your check.

Nearly every page on this subject stops at the birth-year table, and most of them get the table right. The table is the easy part. What follows is the exact month your date falls in, the four birth-date rules that can shift it, and the handful of rules that switch on when you arrive.

What full retirement age actually decides

Full retirement age is the age at which Social Security pays your benefit with no early reduction and no delayed increase.

The federal regulation that defines it, 20 CFR 404.409, sets it as the age for unreduced old-age, wife’s, husband’s, widow’s, and widower’s benefits. Five benefit types, one term. That is precisely why one person can end up holding more than one of these dates, which section six unpacks.

The four things that change on that date

1. Your benefit reaches 100% of your primary insurance amount — the monthly figure Social Security derives from your earnings history. Our guide to how Social Security calculates your benefit from your best 35 years walks through that arithmetic, and the bend points that turn a career average into a monthly figure explains the formula that produces it.
2. The earnings test ends. Beginning with that month, wages no longer reduce your payment, no matter how much you earn.
3. Delayed retirement credits begin. Waiting past the date increases your benefit until age 70.
4. Retroactive payment becomes possible. Social Security cannot pay you for any month before you reached this age.

🔍 How It Works: Your primary insurance amount is calculated once, from your earnings record, and is not tied to any age. Full retirement age is simply the point on the scale where the multiplier applied to it equals exactly 1.00 — below that date the multiplier is under 1, above it the multiplier climbs until 70.

Why it is not the day you stop working

Nothing happens automatically on your full retirement age. It is a date on a calculation, not an event.

You do not have to file that month, stop working that month, or notify anyone. Plenty of people reach it while still employed and never notice.

Find your full retirement age by birth year

Social Security publishes one table, and it has seven rows.

Source: Social Security Administration, Retirement Age and Benefit Reduction chart, certified September 2024, verified August 2026. Percentages are approximate due to rounding, per SSA’s own footnote.

Turning a row into a month

A row gives you a birth year. Your date is a month, and the month is what the arithmetic in the next section runs on.

Add your row’s offset to your birthday month. Someone born in March 1958 reaches 66 in March 2024 and their full retirement age eight months later, in November 2024. You can estimate your own benefit at that date once you know which month it is.

Why the table has stopped growing

The 1983 law that created this schedule raised the age gradually, beginning with people born in 1938 and finishing at 67 for everyone born in 1960 or later. That phase-in is now ending.

The 1959 group — the last with an age below 67 — reaches it across late 2025 and 2026. The first people to reach 67 under the final rule are the 1960 group, in early 2027. By our reading of SSA’s own table and birth-date rules, the closing weeks of 2026 are effectively the seam between the two, with almost nobody arriving at a full retirement age in that window.

What each month before or after that date is worth

The reduction for filing early is not a flat annual rate, which is why two people the same age can face different percentages.

The two-tier reduction

Social Security reduces your benefit by five-ninths of 1% for each of the first 36 months before your full retirement age, then five-twelfths of 1% for every additional month.

🔍 How It Works: Five-ninths of 1% is about 0.556% a month, or roughly 6.67% a year. Five-twelfths of 1% is about 0.417% a month, or roughly 5% a year. For someone whose age is 67, filing at 62 means 36 months at the higher rate of reduction plus 24 at the lower one — 20% plus 10%, which is where the 30% in the table comes from.

Spouse’s benefits use their own scale. A spouse’s maximum is half the worker’s unreduced amount, and SSA states that where full retirement age is 67, a spouse claiming at 62 receives 32.5% of the worker’s figure rather than 50%.

The 8% that stops at 70

For anyone born in 1943 or later, delaying past full retirement age adds 8% a year — two-thirds of 1% for each month — and the increase stops at 70. There is nothing to gain by waiting past 70.

Whether those percentages produce a large or small dollar change depends entirely on your record, which is why what retired workers actually receive and the years missing from your record matter more than the multiplier does.

Two timing rules that surprise people

⚠️ Costly Mistake: If you file between your full retirement age and 70, some of your delayed credits are not applied until the January after your benefits start. SSA’s own example: someone reaching 67 in June who files at 69 initially receives credits only through the year before their 69th birthday, with the rest added the following January. The money is not lost, but a lower first payment is not an error to call about.

Separately, Social Security cannot pay retroactive benefits for any month before you reached full retirement age, and never more than six months back. Back payments received in one year for an earlier year have their own tax treatment, and the IRS explains the lump-sum election for benefits paid for a prior year.

✅ Action Step: Before filing, ask a Social Security representative one specific question: “In which month do I reach full retirement age, and how many months before or after it will my chosen start date fall?” That number, not your age in years, is what sets your percentage.

The birth-date rules that move your date

Your birth year sets the row, but three separate rules about your birth date decide the month — and one of them can move you into a different row entirely.

Born on 1 January. SSA determines your full retirement age using the previous year. Someone born on 1 January 1960 is treated as a 1959 birth, giving them 66 and 10 months rather than 67.

Born on the first of any month. SSA figures your benefit and your full retirement age as though your birthday fell in the previous month.

The 62 rule. You must be at least 62 for an entire month to receive a benefit for it, which is why a birthday late in the month pushes your first possible payment.

⚠️ Costly Mistake: A separate statutory line sits at 2 January 1954 and has nothing to do with full retirement age. Anyone born on or after that date is subject to deemed filing: applying for one of retirement or spouse’s benefits automatically applies for the other. People who have heard of “the January 2 rule” routinely attach it to the wrong thing.

One day of birth date, then, can be worth two months of full retirement age. It is worth checking rather than assuming, and your Social Security Statement lists benefit estimates at nine different ages so you can see the effect on your own record.

Why a widow or widower can have two full retirement ages

The survivor benefit runs on a different schedule from your own retirement benefit, and the survivor date usually arrives earlier — which is favourable, and which almost nobody is told.

Social Security publishes the survivor schedule separately: full retirement age for survivors is 66 for those born from 1945 through 1956, rises gradually for births from 1957 to 1962, and reaches 67 for anyone born in 1962 or later. Its own publication points out that this differs from the retirement schedule, which reaches 67 at 1960.

The practical result is that anyone born from the mid-1950s through 1961 has a survivor date that lands before their retirement date. Survivor benefits can start as early as 60 — 50 with a qualifying disability — paying between 71% and 99% of the worker’s amount before that date and 100% from it.

A note on precision: SSA now serves the year-by-year survivor table only through an interactive form, so this article publishes the endpoints it states in writing and does not print the intermediate rows. Confirm your own survivor date directly with SSA rather than working from any chart, including ours.

The window nobody mentions

Here is where the two dates collide. SSA applies the annual earnings test using your full retirement age for retirement benefits — and states plainly that although the survivor age may be earlier, the retirement age is the one used, and that this holds even for someone not entitled to retirement benefits at all.

So a widow who has reached her survivor date is receiving 100% of that benefit while her earnings can still reduce it, until her separate retirement date arrives. In 2026 the limit before that date is $24,480, with $1 withheld for every $2 above it.

💡 Expert Note: Social Security’s guidance is explicit that withheld months are not lost — it recalculates the benefit at full retirement age to give credit for them. That is the single most reassuring fact in this section for anyone still working.

✅ Action Step: If you are claiming as a survivor, ask Social Security directly: “Which of my two full retirement ages applies to the benefit I am claiming, and which one ends the earnings test for me?” Survivor claims also rest on the work credits the deceased earned, which a representative can confirm at the same time.

What full retirement age is not

Three confusions cost people real money, and the first is the most common.

Medicare still starts at 65

Medicare eligibility is age 65 and has never moved with full retirement age. Social Security tells people to sign up roughly three months before their 65th birthday even if they are not claiming benefits, because Part B and Part D can cost more permanently if you enrol late.

There are two wrinkles. If you are covered by a group health plan through your own or a spouse’s current employment, a Special Enrolment Period lets you delay Part B without penalty. And because premium-free Part A can be backdated six months, contributions to a health savings account should stop six months before you apply.

Nothing has changed since 1983

Under current law the full retirement age is 67 for everyone born in 1960 or later, and no change has been enacted since the 1983 amendments.

The Congressional Budget Office has costed an option that would raise it by two months per birth year for people born from 1964 through 1981, reaching 70. That is an analysed option, not a bill and not law — and it is worth knowing that its first affected group, births in 1964, is exactly the cohort turning 62 now, which is why the headlines feel current.

Reaching full retirement age also does not change how your benefits are taxed; the IRS thresholds for taxing Social Security benefits run on income, not age. For the years between leaving work and your date, the rule of 55 for 401(k) access and catch-up contributions in your fifties are the two levers most people have.

Common questions about full retirement age

Confirm your own date before you file

The birth-year table is the part everyone already has. The month is the part that decides your percentage, and the second date — survivor, spousal, or earnings-test — is the part that catches people out.

Two things are worth doing this week. Work out the exact month from your own birth date using the rules in section five, then confirm it with Social Security rather than any chart.

After that, the useful question stops being when and becomes what happens in between. Our retirement calculator models the gap between now and that date, and retirement savings benchmarks by age covers what to do with the years before you get there.
