You turn 63 this year, and the mail keeps showing up. A Social Security postcard. A Medicare brochure. A flyer from a financial advisor who somehow already has your address. All of it is circling the same question: when do you actually claim.
The average retired worker collects $2,071 a month in 2026, and the maximum benefit at full retirement age tops out at $4,152. Where you land in that range depends almost entirely on decisions made in the twelve months before you file, not after. Once your first payment lands, several of those decisions are locked in for good.
None of this is intuitive. Social Security runs on its own vocabulary, and a wrong guess is hard to undo once benefits start.
Your earnings record comes first. Get that wrong and every other number on this list is wrong too.
Pull your earnings statement and check it for gaps
Create a free my Social Security account if you don't already have one, then open your Social Security Statement and read the earnings history line by line. Your benefit is calculated from your highest 35 years of earnings, so a year that's missing or shows the wrong amount doesn't just look messy. It can permanently shrink your monthly check, sometimes by a meaningful amount if it replaces a high-earning year with a zero.
Errors show up more often than people expect, especially after a job change, a period of self-employment, a name change from marriage or divorce, or simple payroll mistakes that never got caught. Compare each year on the Statement against your own W-2s or tax returns going back as far as you've kept them. Self-employed people should double check that their reported net earnings match what they actually paid Social Security tax on, since underreporting in a low-cash-flow year is common and easy to miss.
If you find a discrepancy, gather your proof first: old W-2s, tax returns, pay stubs, anything dated. Errors can take time to correct, and the earlier in your final working year you catch one, the more likely it is to be fixed before it affects your benefit calculation.
Settle on the claiming age that actually fits your situation
If you were born in 1960 or later, your full retirement age is 67. Claim at 62 and your benefit is cut by roughly 30% for life. Wait until 70 and you collect delayed retirement credits worth about 8% more for every year past full retirement age, on top of any cost-of-living increases along the way.
There's no universally right answer, but there is a wrong way to decide: guessing. The right inputs are your health, your family's longevity, whether you have other income to bridge the gap if you wait, and whether you're still working.
People in poor health or with a family history of shorter lifespans often come out ahead claiming earlier, since they may not live long enough for delayed credits to pay off the years of smaller checks they skipped. People in good health with savings to draw from in the meantime often come out ahead waiting, since Social Security is one of the only guaranteed, inflation-adjusted income sources most retirees will ever have. If you're married, this decision gets more complicated and more important, since it also sets the floor for what your spouse could eventually receive as a survivor.
Find out what you could get as a spouse or survivor
If you're married, you could be eligible for up to half of your spouse's benefit at their full retirement age, even if you have little or no work history of your own. Social Security pays whichever is higher, your own benefit or the spousal amount, never both stacked together. If you're divorced, you may still qualify on an ex-spouse's record as long as the marriage lasted at least 10 years and you haven't remarried, and your ex doesn't even need to know you've applied.
Survivor benefits work differently and are worth understanding now, not after a spouse has died. A surviving spouse can receive between 71.5% and 100% of the deceased spouse's benefit, depending on the survivor's age when they claim, with the full amount available at the survivor's own full retirement age. This is one of the strongest arguments for the higher-earning spouse in a couple to delay claiming as long as possible: that decision sets the ceiling for what the surviving spouse can eventually collect, sometimes for decades.
If any of this applies to you, ask your spouse or ex-spouse for their estimated benefit amount, or use your own my Social Security account to run the comparison before you file. Filing without checking can mean leaving money on the table permanently.
Run the numbers if you're claiming early and still working
Planning to claim before full retirement age while you're still earning a paycheck? Social Security will temporarily withhold part of your benefit if you earn over a set amount. For 2026, that limit is $24,480 a year, or $2,040 a month, for anyone who'll be under full retirement age for the entire year. Earn more than that and Social Security withholds $1 in benefits for every $2 you make above the limit.
The rule loosens in the calendar year you actually reach full retirement age. The limit jumps to $65,160 for that year, and the withholding rate drops to $1 for every $3 over the limit, applying only to earnings in the months before your birthday. Once you hit full retirement age, the earnings test disappears entirely and you can earn any amount without losing a dollar of benefits.
It's not lost money forever. Once you reach full retirement age, Social Security recalculates your benefit going forward to credit you for the months it withheld. But the cash flow hit happens now, while the credit shows up later, so it's worth mapping out whether claiming early while still working actually makes financial sense for your specific year, or whether it's smarter to wait those last few months.
Line up Medicare before your birthday catches up with you
Medicare and Social Security run on separate clocks, and missing the Medicare one is expensive and permanent. Your Initial Enrollment Period runs seven months: it starts three months before the month you turn 65, includes your birthday month, and ends three months after. Miss that window without qualifying coverage from a current employer, and you can face a late enrollment penalty added to your Part B premium for as long as you have Medicare.
If you're already collecting Social Security when you turn 65, enrollment in Medicare Part A and Part B happens automatically. If you haven't filed for Social Security yet, you'll need to sign up for Medicare on your own, even if you're not ready to claim retirement benefits. The standard Part B premium for 2026 is $202.90 a month, with a $283 annual deductible, and higher earners pay more under the income-related surcharge.
If you're still covered by a current employer's group health plan when you turn 65, you may be able to delay Part B without a penalty, but the rules depend on the size of the employer and whether the coverage counts as primary. This is worth confirming with your HR department directly rather than assuming, since getting it wrong can mean a permanent premium increase.
Figure out how much of your benefit the IRS will want
Social Security isn't automatically tax-free. Whether yours is taxed depends on your “combined income,” which is your adjusted gross income plus any tax-exempt interest plus half of your annual benefit. If that combined figure tops $25,000 filing individually or $32,000 filing jointly, a portion of your benefit becomes taxable, up to 85% at higher income levels. These thresholds haven't budged in decades, so more retirees get pulled into them every year as benefits rise with inflation.
There's a new wrinkle worth knowing about for 2026: taxpayers 65 and older can now claim an additional $6,000 deduction, on top of the regular standard deduction, through tax year 2028. It phases out above $75,000 in modified adjusted gross income for individuals and $150,000 for joint filers. It doesn't change how Social Security itself gets taxed, but it can lower your overall taxable income enough to matter, especially if you're close to one of the combined-income thresholds.
If a tax bill at filing time would catch you off guard, you can ask Social Security to withhold a percentage of your monthly benefit for federal taxes instead of paying it all at once the following spring.
Get your real benefit estimate, not the projected one
The numbers on your paper Statement assume you keep earning at roughly your current pace until you claim. If you're planning to retire early, cut back your hours, or take a lower-paying job before you actually file, your real benefit could land meaningfully below the projection. Your my Social Security account lets you plug in different stop-working dates and claiming ages to see how the number actually moves, rather than relying on an estimate built on assumptions that no longer match your plan.
This is also where you can model out spousal numbers side by side, comparing your own benefit against a spousal benefit if you're married, or checking what a survivor benefit would look like if your spouse claims first. Run a few different ages, from 62 through 70, and look at the totals, not just the monthly amount. A smaller monthly check claimed five years earlier can still add up to less lifetime income than a larger check claimed later, depending on how long you expect to collect.
Decide if you need a financial advisor or just a calculator
Not everyone needs to pay for advice here. If your situation is simple, one income source, no pension, no complicated spousal timing, your own Social Security account and a few hours of research may be all you need. The math isn't secret, it's just unfamiliar.
Where it gets harder to do alone: you have a pension from work that didn't pay into Social Security, you're weighing claiming strategies across a marriage with a significant income gap, you're managing taxable retirement accounts alongside Social Security and want to coordinate withdrawals to control your tax bracket, or you simply don't trust your own math under pressure. In any of those cases, a financial advisor who specializes in retirement income can be worth the fee.
If you do bring someone in, confirm they're a fiduciary, meaning they're legally required to act in your interest rather than just recommend something “suitable.” You can check any advisor's licensing and background for free before you hand over your financial life. Paying for a single consultation to stress-test your own plan is often enough. You don't need a permanent advisory relationship just to make one good decision.
