Key points
- You qualify for a retirement benefit with 40 Social Security credits, about 10 years of work. The amount comes from your highest 35 years of earnings, adjusted for wage growth.
- You can start at any age from 62. With a full retirement age of 67, starting at 62 pays 70% of your full benefit and waiting until 70 pays 124%, the most. The cut for starting early is permanent.
- A spouse can get up to 50% of the worker’s full benefit. A widow or widower at full retirement age generally gets 100% of the worker’s benefit, including any delayed credits.
- Benefits rise 3.6% in January 2027, and up to 85% of them can be taxable. The 2026 Trustees Report projects that once the reserves of the trust fund for retirement and survivor benefits run out in late 2032, incoming taxes would cover 78% of scheduled benefits, if Congress does nothing.
Social Security pays monthly benefits to people who paid Social Security tax long enough, and to their spouses, former spouses, children and survivors. Nearly 72 million people get them, according to the Social Security Administration (SSA).
This guide covers the whole system briefly and links to deeper guides on each question. It covers federal rules, not state income tax.
We checked every rule and figure on October 27, 2026 against SSA’s publications, actuarial pages and operations manual, the Social Security Act and regulations (20 CFR part 404), the tax code, IRS Publication 915, Public Law 118-273, the 2026 Trustees Report and Medicare.gov. They are listed at the end. To run your own numbers, use our Social Security calculator.
How Social Security benefits work
Social Security is paid for mainly by payroll tax. Employees pay 6.2% of wages up to a yearly cap, and employers pay the same. The cap is $184,500 for 2026 and $192,300 for 2027. Self-employed people pay 12.4%. So in 2027 a worker earning $192,300 or more pays $11,922.60, and the employer pays the same.
Paying it earns credits toward benefits for you and your family. The main monthly benefits are:
- Retirement benefits on your own work record, from 62.
- Spouse and divorced spouse benefits, up to half of the worker’s full benefit.
- Survivor benefits for a widow or widower, children and dependent parents.
- Disability benefits for workers who cannot work because of health problems. SSA says the amount “is the same as a full, unreduced retirement benefit,” and it becomes a retirement benefit at full retirement age.
Social Security replaces part of your pay: SSA estimates that a benefit started at 67 replaces about 42% of a medium earner’s average wages, as much as 78% for very low earners and about 28% for high earners.
Your earnings record and benefit estimates are in a personal “my Social Security” account at ssa.gov/myaccount, where you can “see the effects of different ages to begin receiving retirement benefits.”
Who qualifies: Social Security credits
You need 40 credits to qualify for retirement benefits on your own record. That is 10 years of work at the maximum of four credits a year.
A credit is a set amount of covered earnings (wages or net self-employment income). The amount rises each year:
| Year | Earnings for one credit | Earnings for the maximum four |
|---|---|---|
| 2026 | $1,890 | $7,560 |
| 2027 | $1,970 | $7,880 |
You can earn at most four credits a year, however much you earn. Credits stay on your record if you stop working, and SSA adds new ones if you go back.
Credits decide only whether you qualify. In SSA’s words: “The number of credits does not affect the amount of benefits you receive.” Your earnings set the amount.
Work that did not pay Social Security tax, such as some state and local government jobs, earns no credits. More in our guide to Social Security credits.
How is your Social Security benefit calculated?
SSA first works out one number: your primary insurance amount (PIA). That is your monthly benefit if you start at your full retirement age. Early and late claiming, spouse benefits and survivor benefits are all percentages of it.
- Index your earnings. Each year’s earnings, up to that year’s taxable maximum, are adjusted for the growth in average wages up to your indexing year. That is the second year before the year you turn 62, so the year you turn 60. Earnings from then on count at face value.
- Take your highest 35 years. SSA adds your 35 highest indexed years and divides by the months in them (420). If you worked fewer than 35 years, the missing years count as zero. The result, rounded down to the dollar, is your average indexed monthly earnings (AIME).
- Apply the formula. Your PIA is 90% of the first slice of your AIME, plus 32% of the middle slice, plus 15% of the rest. The dividing lines, called bend points, depend on the year you turn 62.
| Year you turn 62 | 90% of AIME up to | 32% of AIME from there to | 15% of AIME above |
|---|---|---|---|
| 2026 | $1,286 | $7,749 | $7,749 |
| 2027 | $1,340 | $8,077 | $8,077 |
The PIA is rounded down to the next 10 cents. From December of the year you turn 62, it also gets each year’s cost-of-living increase, whether or not you have started benefits.
Example. You turn 62 in 2027 (born in 1965) and your AIME is $6,000. Your PIA is:
- 90% of the first $1,340: $1,206.00
- 32% of the next $4,660 (from $1,340 to $6,000): $1,491.20
- nothing at 15%, because $6,000 is below $8,077
PIA: $2,697.20 a month, before cost-of-living increases from December 2027 on. The first dollars of AIME are replaced at 90% and the last at 15%, so the formula replaces a larger share of pay for lower earners.
Two related figures:
- The maximum benefit for a worker retiring at full retirement age is $4,152 a month in 2026 and $4,188 in 2027. SSA’s worked example of a top earner assumes maximum-taxable earnings in every year since age 22. See the maximum Social Security benefit.
- The average retired worker gets an estimated $2,095 a month before the 2027 increase and $2,170 after it. See the average Social Security check.
The full method, step by step, is in how Social Security is calculated.
Full retirement age by birth year
Your full retirement age is when you can get 100% of your PIA. For anyone born in 1943 or later it is between 66 and 67.
| Year of birth | Full retirement age |
|---|---|
| 1943 to 1954 | 66 |
| 1955 | 66 and 2 months |
| 1956 | 66 and 4 months |
| 1957 | 66 and 6 months |
| 1958 | 66 and 8 months |
| 1959 | 66 and 10 months |
| 1960 and later | 67 |
Two quirks. If you were born on January 1, use the previous year. And if you were born on the 1st of any month, SSA figures your benefit as if your birthday were in the month before.
Survivor benefits use a different full retirement age: 66 for survivors born from 1945 to 1956, rising to 67 for those born in 1962 or later. More in our guide to full retirement age.
Claiming at 62, 67 or 70: how much you get at each age
You can start retirement benefits in any month from 62 on. Starting before full retirement age cuts the benefit. Starting after it adds delayed retirement credits, up to 70; waiting past 70 adds nothing more.
- Early: the cut is 5/9 of 1% for each of the first 36 months before full retirement age and 5/12 of 1% for each month beyond that. The Social Security Handbook is plain about it: “This reduction is permanent.”
- Late: for anyone born in 1943 or later, each month you wait past full retirement age adds 2/3 of 1%, which is 8% a year.
With a full retirement age of 67 (born in 1960 or later), the percentages are:
| Start at | Your own benefit, % of your PIA | Spouse benefit, % of the worker’s PIA |
|---|---|---|
| 62 | 70% | 32.5% |
| 63 | 75% | 35% |
| 64 | 80% | 37.5% |
| 65 | 86.7% | 41.7% |
| 66 | 93.3% | 45.8% |
| 67 | 100% | 50% |
| 68 | 108% | 50% |
| 69 | 116% | 50% |
| 70 | 124% | 50% |
The spouse column goes by the spouse’s own age when the spouse benefit starts. Spouse benefits earn no delayed credits, so they stop growing at full retirement age.
Two timing rules. You must be 62 for the whole month to get a benefit for that month, so a start at 62 pays exactly 70% only if you were born on the 2nd of a month; for anyone else the first month at 62 is one month closer to full retirement age, with a slightly smaller cut. And if you start after full retirement age but before 70, the credits earned in the year you start are added the following January.
Example. You were born on March 2, 1965, so your full retirement age is 67, and your PIA is $2,000. In today’s dollars your monthly check would be:
- $1,400 starting at 62
- $2,000 starting at 67
- $2,480 starting at 70
Run these numbers in the calculator.
Waiting means fewer checks, but bigger ones. The break-even age is when the total from waiting catches up with the total from starting earlier. Here, starting at 67 instead of 62 catches up at 78 and 8 months. Starting at 70 instead of 67 catches up at 82 and 6 months. Counting every check up to age 85, the totals are $386,400 starting at 62, $432,000 at 67 and $446,400 at 70. These totals add the checks; they leave out cost-of-living increases, taxes and any return on checks you save.
A break-even age means something only next to how long you might live. Our life expectancy calculator uses Social Security’s own period life table.

Spousal benefits: up to half of your spouse’s full benefit
A husband or wife can get a benefit on the other’s record of up to 50% of the worker’s PIA. In general:
- the worker has filed for their own benefit
- the spouse is 62 or older, or any age while caring for the worker’s child who is under 16 or disabled and gets benefits on the worker’s record
- the marriage has lasted at least a year, with some exceptions.
If it starts before the spouse’s own full retirement age, the spouse benefit is cut, to as little as 32.5% of the worker’s PIA at 62 when full retirement age is 67 (see the table above).
The spouse benefit is not added in full on top of the spouse’s own benefit. SSA pays your own retirement benefit first. If half the worker’s PIA is more than your own PIA, it adds the difference, which SSA’s manual calls the excess spouse’s benefit. Each part is cut for age on its own: your own benefit for the month you started it, the excess only for months it is paid before your full retirement age. An early cut to your own benefit stays, so the total can end up below the full spouse amount (third case below).
Deemed filing. If you were born on or after January 2, 1954 and qualify for both your own benefit and a spouse benefit, applying for one counts as applying for both. You cannot take one and leave the other to grow.
The worker’s delayed credits do not raise a spouse benefit. The cap stays at half the worker’s PIA, not half of a larger check earned by waiting. (They do raise a survivor benefit; see below.)
Example. You were born on March 2, 1965 with a PIA of $2,400. Your spouse, born on September 2, 1965, has a PIA of $700 of their own. Both full retirement ages are 67.
- Both start at 67. You get $2,400. Your spouse gets their own $700 plus $500 on your record, $1,200 in all. Household: $3,600 a month.
- You wait until 70; your spouse starts at 67. You get $2,976 from 70. Your spouse gets $700 from 67 and the $1,200 total only from when you claim at 70. Household from then on: $4,176 a month.
- You wait until 70; your spouse started their own benefit at 62. Your spouse’s own check is $490 (70% of $700). The $500 excess is added in full from when you claim, because your spouse is past full retirement age by then, but the early cut stays: $990 a month, not $1,200.
Run this couple in the calculator, then change your claiming age to 67 to see the first case, or your spouse’s to 62 to see the third.
A family as a whole has a limit, the family maximum. Social Security says it varies between 150% and 180% of the worker’s benefit. If the spouse and children are due more, their benefits are reduced; the worker’s is not. More in Social Security spousal benefits.
Divorced spouse benefits
You can get a spouse benefit on a former husband’s or wife’s record if:
- the marriage lasted at least 10 years before the divorce became final
- you are not married now
- you are 62 or older
- your own PIA is less than half of your ex’s PIA, the full spouse benefit.
Your ex does not have to have claimed, as long as you have been divorced for at least 2 years and your ex is at least 62 and has the work credits to qualify for retirement benefits.
Your benefit does not reduce what your ex or your ex’s current spouse gets. The deemed filing rule applies to divorced spouses too. More in divorced spouse Social Security.
Survivor benefits
When a worker dies, a widow or widower can get:
- generally 100% of the worker’s benefit at the survivor’s own full retirement age (66 to 67)
- 71.5% at 60, the earliest age, rising for each month the survivor waits
- reduced benefits from 50 if the survivor is disabled
- 75% at any age while caring for the worker’s child who is under 16 or disabled.
The survivor benefit is figured from the worker’s benefit. If the worker waited past full retirement age, the delayed credits carry over to the survivor. If the worker started early, the survivor benefit is limited to the larger of what the worker was getting or 82.5% of the worker’s PIA.
Example. Take the couple above. If you waited until 70 and then died, your spouse, at full retirement age, would get $2,976 a month in place of their $1,200; the survivor note under the couple link above shows it. If you had started at 62 with $1,680, your spouse at full retirement age would get $1,980, which is 82.5% of your $2,400 PIA, because that is larger than your check. Run the start at 62 in the calculator: its survivor note shows the $1,980.
Other survivor rules:
- One benefit, not two. If you qualify for a survivor benefit and your own retirement benefit, SSA pays one, not both added together. You can switch later: for example, take the survivor benefit first and switch to your own at 70. Deemed filing does not apply to survivor benefits.
- Marriage length. Generally at least 9 months before the death. A surviving divorced spouse needs a marriage of at least 10 years.
- Remarriage. Remarrying before 60 (50 if disabled) usually ends eligibility. Remarrying after that age does not.
- A one-time $255 payment can go to a surviving spouse or child who meets SSA’s rules and applies within 2 years of the death.
More in Social Security survivor benefits.
Working while collecting: the earnings limit
If you start benefits before full retirement age and keep working, SSA holds back benefits when your earnings pass a yearly limit. This is the retirement earnings test.
| When | 2026 limit | 2027 limit | Benefits withheld |
|---|---|---|---|
| Under full retirement age all year | $24,480 | $25,560 | $1 for every $2 over |
| Year you reach full retirement age, months before it | $65,160 | $67,920 | $1 for every $3 over |
| From the month you reach full retirement age | None | None | None |
Only wages and net self-employment income count. Pensions, investment earnings, interest, annuities and capital gains do not.
Example. You turn 64 in 2027 (under full retirement age all year). Your benefit is $1,500 a month and you earn $35,560. That is $10,000 over the $25,560 limit, so SSA withholds $5,000. It does this by holding back whole checks from the start of the year, here the first four ($6,000), and paying the $1,000 it held back beyond the $5,000 the next year, the way SSA’s own example works.
The $5,000 is not refunded, but it is not lost: at full retirement age SSA raises your monthly benefit to account for the months it held back. And in one year, usually your first year of retirement, a monthly rule pays a full check for any month you earn no more than a monthly limit, whatever your earnings for the year. For people under full retirement age all year, that limit is $2,040 a month in 2026 and $2,130 in 2027.
More in the Social Security earnings limit. From full retirement age to 70 you can also pause your benefits to earn delayed credits; see suspending Social Security.
Is Social Security taxable?
Up to 85% of your benefits can be subject to federal income tax. Whether any part is depends on a figure SSA calls combined income and SSA’s researchers call provisional income:
Provisional income = your other income + tax-exempt interest + half of your Social Security benefits
| Filing status | Up to 50% taxable above | Up to 85% taxable above |
|---|---|---|
| Single, head of household or qualifying surviving spouse | $25,000 | $34,000 |
| Married filing jointly | $32,000 | $44,000 |
| Married filing separately, lived with your spouse at any time in the year | $0 | $0 |
Married people filing separately who lived apart all year use the single amounts. The thresholds are written into the tax code and are not adjusted for inflation; the Trustees note they “have never been changed.” SSA says about 40% of people who get Social Security pay income tax on their benefits.
Example. A single filer gets $30,000 of Social Security and has $25,000 of other income. Provisional income is $25,000 plus $15,000, or $40,000, which is over $34,000. Following the Publication 915 worksheet, $9,600 of the benefits is taxable: $4,500 from the 50% tier plus $5,100, which is 85% of the $6,000 above $34,000. That is 32% of the benefits. The other $20,400 is tax-free. The $9,600 goes into gross income and is taxed like other ordinary income.
You can have federal tax withheld from each check at 7%, 10%, 12% or 22% (IRS Form W-4V), or pay estimated tax instead.
For 2025 through 2028, people 65 and older can also take a new deduction of $6,000 each, phasing out above modified adjusted gross income of $75,000 ($150,000 for joint filers). It is a deduction, not a change to the test above: Publication 915 for 2025 returns keeps the same $25,000 and $32,000 base amounts.
Taxable withdrawals from IRAs and 401(k)s count as other income, so a required minimum distribution can make more of your benefits taxable; see how RMDs are taxed. Deeper guides: is Social Security taxable? and provisional income.
Social Security COLA for 2027: 3.6%
Benefits rise each year with a cost-of-living adjustment (COLA). For 2027 it is 3.6%, after 2.8% for 2026. It starts with the December 2026 benefit, which is paid in January 2027.
The COLA is the rise in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of the last year with a COLA to the third quarter of this year, rounded to the nearest tenth of a percent. For 2027 the average went from 317.265 in the third quarter of 2025 to 328.746 in the third quarter of 2026: a 3.6% rise.
On a $2,000 check, 3.6% adds $72, to $2,072. SSA estimates the average retirement benefit rises by $75 a month, from $2,095 to $2,170.
If you have Medicare Part B, the premium is generally deducted from your Social Security check, so the raise you see is the COLA minus any increase in the premium. The 2027 Part B premium had not been published on October 27, 2026; SSA says the 2027 amount will be in the “my Social Security” Message Center starting in late November.
More in the Social Security COLA.
The Social Security Fairness Act: WEP and GPO are gone
The Social Security Fairness Act (Public Law 118-273), signed on January 5, 2025, repealed two rules that cut benefits for people with a pension from work that did not pay Social Security tax:
- the Windfall Elimination Provision (WEP), which reduced their own retirement or disability benefit
- the Government Pension Offset (GPO), which reduced or wiped out spouse and survivor benefits.
The repeal applies to benefits payable for months after December 2023. Because benefits are paid a month behind, the January 2024 benefit was generally received in February 2024.
The law helps people with a pension from work not covered by Social Security: some teachers, firefighters and police officers in many states, federal employees under the Civil Service Retirement System, and people whose work was covered by a foreign social security system. SSA says about 72% of state and local public employees work in covered jobs, so their benefits do not change.
SSA reports that by July 7, 2025 it had sent over 3.1 million payments, totaling $17 billion, covering increases back to January 2024. Someone who never applied because of WEP or GPO needs to file an application, and the date of the application can affect when benefits begin. The law did not change the limits on back benefits: for some retirement and survivor claims, SSA says they are generally limited to six months before the month of the application.
More in the Social Security Fairness Act.
Is Social Security running out of money? The 2026 Trustees Report
Running out of reserves would not stop the checks. Payroll taxes keep coming in, and the Trustees project they would cover most scheduled benefits:
| Trust fund | Reserves projected to run out | Share of scheduled benefits payable then | Share by 2100 |
|---|---|---|---|
| Retirement and survivors (OASI) | Fourth quarter of 2032 | 78% | 62% |
| Retirement, survivors and disability combined (OASDI) | Third quarter of 2034 | 83% | 65% |
These are projections under current law, not cuts written into law. Congress can change taxes or benefits before then, and the Trustees “recommend that lawmakers address the projected trust fund shortfalls in a timely way.” The combined line assumes the law is changed to let the two funds share money; under current law, one trust fund cannot use the other’s money.
Example. For the $2,000 PIA above, the 78% projection applied from January 2033, the first full year after the projected depletion, would cut the check started at 67 from $2,000 to $1,560 a month, in today’s dollars. The calculator link above shows it. The calculator holds the cut at 78%; the Trustees project the payable share falling to 62% by 2100.

How and when to apply for Social Security
You can apply up to four months before you want benefits to start: online at ssa.gov, by phone at 1-800-772-1213, or by appointment at a local Social Security office.
SSA may ask for documents such as your birth certificate, last year’s W-2 forms or self-employment tax return and your bank details for direct deposit. SSA’s advice: “Don’t delay your application for benefits if you don’t have all the information.”
Four rules to know before you apply:
- Start month. Once you are past full retirement age, you can ask for back benefits, but not for months before full retirement age or more than six months in the past.
- Medicare is separate. You can sign up for Medicare without starting Social Security. SSA says that if you delay benefits past 65, “you should still apply for Medicare benefits within 3 months of your 65th birthday.”
- Changing your mind. You can withdraw a retirement application only once, within 12 months of your first month of benefits, and you must repay the benefits you and your family received. SSA’s web page counts the 12 months from approval; the regulation counts from the first month you are entitled, which can be earlier. More in suspending or withdrawing Social Security.
- Pausing. From full retirement age to 70 you can ask SSA to suspend payments and earn delayed credits. Payments restart automatically at 70. While yours are suspended, benefits to anyone else on your record are suspended too, except a divorced spouse’s.
More in how to apply for Social Security retirement.
When Social Security payments arrive
Benefits are paid a month behind. In SSA’s words: “We pay Social Security benefits the month after they are due.” So if your first month of benefits is March, your first payment comes in April.
Your payment day generally depends on the birth date of the person whose work record you are paid on: yours for your own retirement benefit, your spouse’s if you get benefits on your spouse’s work.
| Date of birth | Paid on |
|---|---|
| 1st to 10th | Second Wednesday of the month |
| 11th to 20th | Third Wednesday |
| 21st to 31st | Fourth Wednesday |
Social Security is paid on the 3rd instead if benefits on that work record started from an application filed before May 1997, or if you also get Supplemental Security Income (SSI), live outside the US, or have your Medicare premium paid by your state.
The 2026 and 2027 dates are in the Social Security payment schedule.
Key Social Security numbers for 2026 and 2027
| Item | 2026 | 2027 |
|---|---|---|
| Cost-of-living adjustment | 2.8% | 3.6% |
| Taxable maximum earnings | $184,500 | $192,300 |
| Earnings for one credit | $1,890 | $1,970 |
| Earnings limit, under full retirement age | $24,480 | $25,560 |
| Earnings limit, year you reach full retirement age | $65,160 | $67,920 |
| Maximum benefit at full retirement age | $4,152 | $4,188 |
| Bend points, by the year you turn 62 | $1,286 and $7,749 | $1,340 and $8,077 |
SSA recalculates all of these every year. It published the 2027 figures with the COLA on October 14, 2026. The tax thresholds ($25,000 and $34,000 single, $32,000 and $44,000 joint) do not change.
