The best age to take Social Security is the one that fits your health, your work plans, your spouse’s situation, and how long you expect to live. You can start as early as 62 or wait as late as 70. Filing at 62 locks in a permanently reduced check. Waiting past your full retirement age adds 8% for every year you delay, up to age 70. Everything else, from the earnings test to survivor benefits to income taxes, flows from that one choice.
What Each Filing Age Actually Pays
Your benefit is built around your Primary Insurance Amount, which is what you’d collect at full retirement age with no reduction and no bonus. For anyone born in 1960 or later, full retirement age is 67. Born between 1955 and 1959, it slides in two-month steps from 66 and two months up to 66 and ten months. Born 1943 to 1954, it’s 66.1eCFR. 20 CFR 404.409 – What Is Full Retirement Age?
File before that age and the SSA cuts your monthly check by 5/9 of 1% for each of the first 36 months early, then 5/12 of 1% for every additional month.2Social Security Administration. 20 CFR 404.410 – How Does SSA Reduce My Old-Age Benefits? If your full retirement age is 67 and you file at 62, that’s 60 months early and a permanent 30% cut. File at 63 and you lose about 25%. File at 65 and you lose about 13.3%.3Social Security Administration. Benefits Planner – Retirement Age and Benefit Reduction
Wait past full retirement age and you earn delayed retirement credits of 2/3 of 1% per month, or 8% a year.4eCFR. 20 CFR 404.313 – What Are Delayed Retirement Credits and How Do They Increase My Old-Age Benefit Amount? Someone with a full retirement age of 67 who waits until 70 collects 24% more for the rest of their life than they would have at 67. The maximum possible monthly check for someone filing at 70 in 2026 is $5,181, and that assumes taxable-maximum earnings in every working year since age 22.5Social Security Administration. What Is the Maximum Social Security Retirement Benefit Payable?
Credits stop accumulating at 70. There is no reason to wait past that birthday. File shortly before it if you’ve been holding out.
The reduced or increased rate is permanent. Cost-of-living adjustments apply on top of it, but the percentage is applied to your locked-in base, so an early filer never catches up. The 2026 COLA is 2.8%.6Social Security Administration. Social Security Announces 2.8 Percent Benefit Increase for 2026 A $2,000 monthly benefit picks up $56 from that increase; a $2,480 benefit picks up about $69. Small each year, meaningful across decades.
The Break-Even Question
Early filers collect smaller checks for more years. Late filers collect larger checks for fewer years. The point where the delayed filer’s total dollars pass the early filer’s is the break-even, and for most people it lands somewhere between ages 78 and 81.
If you live past that crossover, waiting wins. If you don’t, filing early does. Nobody knows their own date, so the decision comes down to what you can reasonably expect. Family longevity, your current health, and whether you have a chronic condition all belong in the calculation.
When Filing Early Makes Sense
Claiming at 62 is the right call for some people. Serious health problems that shorten life expectancy tip the math toward early filing. So does the absence of other savings, if the alternative is running up high-interest debt to cover living expenses in your 60s. Money in hand at 62 can outweigh a bigger check that arrives years later you may not see.
If you’re still working full-time and thinking about filing early just to start collecting, be careful. The retirement earnings test may take back much of what you claim.
The Earnings Test
File before full retirement age and keep working, and the SSA withholds part of your check once your wages cross a threshold. In 2026, the limit is $24,480 for anyone who won’t reach full retirement age during the year. For every $2 you earn above it, $1 in benefits is withheld.7Social Security Administration. Exempt Amounts Under the Earnings Test
In the calendar year you actually reach full retirement age, a looser rule applies to the months before your birthday month: the limit rises to $65,160, and the withholding drops to $1 for every $3 above it.7Social Security Administration. Exempt Amounts Under the Earnings Test Starting the month you hit full retirement age, the test disappears and you can earn any amount.
Withheld money isn’t lost. Once you reach full retirement age, the SSA recalculates your benefit to credit the withheld months. But if you plan to keep earning a strong salary, the test is a good reason to wait until full retirement age rather than file at 62 and watch checks vanish.
When Waiting Pays Off
Delay works best when you’re healthy, expect a long retirement, and have a way to cover expenses in the meantime, whether that’s continued work, savings, or another income source. The 8% annual increase from delayed credits is a guaranteed return you cannot match reliably in the market, and it compounds through future COLAs.
If you’re past full retirement age and haven’t filed yet, you can claim up to six months of retroactive benefits when you do apply, though the SSA won’t pay retroactively for any month before you reached full retirement age.8Social Security Administration. Delayed Retirement Credits
How a Spouse Changes the Decision
If you’re married, your filing age isn’t just about you. When one spouse dies, the survivor keeps the higher of the two benefits. A worker who delayed to 70 and locked in a 24% larger check hands that larger check to their surviving spouse.9eCFR. 20 CFR 404.338 – Widow’s and Widower’s Benefits Amounts A worker who filed early at a reduced amount caps the survivor benefit at that reduced level, subject to a minimum floor. In a couple where one spouse earned significantly more, having that spouse delay as long as possible protects the survivor for the rest of their life.
Spousal benefits work differently. A spouse can collect up to 50% of the worker’s Primary Insurance Amount, reduced if the spouse files before their own full retirement age.10Social Security Administration. Benefits for Spouses Spousal benefits do not earn delayed retirement credits, so there is no reason to wait past full retirement age to claim one.
Divorced spouses qualify on an ex’s record if the marriage lasted at least ten years, they’re at least 62, and they’re currently unmarried. The same 50% cap and early-filing reduction apply, and claiming does not affect the ex-spouse or their current spouse.11Social Security Administration. Can Someone Get Social Security Benefits on Their Former Spouse’s Record?
Taxes and Medicare
Social Security checks can be taxed federally. The IRS looks at “combined income,” which is your adjusted gross income plus any nontaxable interest plus half your benefits. Single filers with combined income between $25,000 and $34,000 may see up to 50% of benefits taxed; above $34,000, up to 85%. For joint filers, the brackets are $32,000 to $44,000 and above $44,000.12Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits These thresholds have not been adjusted for inflation since 1993.
Your filing age feeds into this. Delaying to 70 produces a larger check that may push more of your benefits into the taxable range. Filing early with substantial pension or 401(k) income can also trigger partial taxation. Most states do not tax Social Security, though some still do.
Medicare has its own timing. If you’re already collecting Social Security at 65, you’re automatically enrolled in Medicare Part A and Part B.13Centers for Medicare & Medicaid Services. Original Medicare (Part A and B) Eligibility and Enrollment If you’re delaying Social Security past 65, you need to sign yourself up during your initial enrollment period, which starts three months before your 65th birthday. Missing it can mean permanent late-enrollment penalties on your Part B premium. Delayers get billed directly for Part B rather than having it withheld from a check.14Medicare.gov.

If You File and Regret It
You get one narrow chance to undo an early filing. Within 12 months of your first month of entitlement, you can withdraw the application by submitting a written request. You have to repay every dollar of benefits paid on your record, including anything paid to family members.15Social Security Administration. Can I Withdraw My Social Security Retirement Claim and Reapply Later? Do that and it’s as if you never filed. Miss the 12-month window and the reduced rate is yours for life.
