If you were born in 1965, your full retirement age for Social Security is 67. You’ll hit that milestone in 2032, and claiming your benefit at that point pays 100 percent of what Social Security calculated from your lifetime earnings. Claim any earlier and the monthly check shrinks permanently. Wait past 67 and it grows by 8 percent a year up to age 70. Medicare, meanwhile, still starts at 65, which creates a two-year planning gap that catches many people off guard.
What Claiming Before 67 Costs You
You can start collecting as early as 62, but the reduction is steep. Social Security cuts your benefit by 5/9 of one percent for each of the first 36 months you claim early, then 5/12 of one percent for each additional month.1Social Security Administration. Early or Late Retirement Filing at 62 puts you 60 months early, which works out to a 30 percent cut.
In dollars, a full benefit of $2,000 at 67 becomes roughly $1,400 at 62. That reduced amount is what you receive for the rest of your life, adjusted only by annual cost-of-living increases.2Social Security Administration. Retirement Age and Benefit Reduction The haircut is permanent, not something you eventually work off.
You can also file at any month between 62 and 67 with a smaller reduction the longer you wait. Filing at 64 costs less than filing at 62 because you’re 36 months early instead of 60. Each month of delay simply trims the penalty a little more.
What Waiting Past 67 Earns You
Every month you delay claiming after 67 adds a delayed retirement credit of 2/3 of one percent, or 8 percent per full year.3Social Security Administration. Delayed Retirement Credits Waiting until 70 makes your monthly check 24 percent larger than it would have been at 67.
Using the same example, delaying to 70 lifts a $2,000 benefit to about $2,480 a month. That higher baseline also anchors every future cost-of-living adjustment, so the gap between claiming at 67 and 70 widens over time. Credits stop building at 70, so there’s no financial reason to wait longer.4Social Security Administration. 20 CFR 404.313 – What Are Delayed Retirement Credits and How Do They Increase My Old-Age Benefit Amount?
The choice between 67 and 70 usually comes down to health and cash flow. If you’re in good shape and can cover expenses without the benefit for a few more years, the boost is hard to beat. If you have serious health concerns or need the income now, locking in at 67 makes more sense. The math generally favors waiting for anyone who lives past roughly 80.
Working While Collecting Before 67
If you claim before 67 and keep working, an earnings test applies. In 2026, you can earn up to $24,480 with no effect on your benefits. Above that, Social Security withholds $1 for every $2 you earn over the limit.5Social Security Administration. Receiving Benefits While Working
A more generous rule takes over in the calendar year you turn 67. In 2026 that limit climbs to $65,160, and only $1 is withheld for every $3 over. Earnings after the month you actually reach 67 don’t count at all.6Social Security Administration. How Work Affects Your Benefits
Once you’re 67, the earnings test disappears. You can earn any amount without a benefit reduction. The withheld money isn’t lost either. Social Security recalculates your monthly benefit at full retirement age to credit back the months payments were withheld, so your ongoing check goes up.5Social Security Administration. Receiving Benefits While Working The withholding feels like a penalty, but it functions more like a forced deferral.
Medicare Still Starts at 65
This is where people born in 1965 most often stumble. Full retirement age for Social Security is 67, but Medicare eligibility begins at 65. They are separate programs on separate timelines, and treating them as one leads to permanent premium penalties.
Your Medicare initial enrollment period runs from three months before you turn 65 through three months after your 65th birthday month.7Medicare.gov. When Can I Sign Up for Medicare? Miss that window without qualifying for an exception and you’ll pay a Part B late enrollment penalty of 10 percent for each full 12-month period you could have been enrolled but weren’t. That penalty stays on your premium for as long as you have Part B.
The main exception is being covered by an employer group health plan through your own or your spouse’s active job at 65. That lets you delay Part B without penalty and sign up in a special enrollment period within eight months of the job ending or the coverage ending.8Social Security Administration. When to Sign Up for Medicare Individual marketplace coverage and self-employment insurance don’t qualify. If that’s your situation, enroll at 65 even if Social Security is still two years away.
How Your Claim Age Affects a Spouse
The maximum spousal benefit is 50 percent of your full benefit at 67, and your spouse gets that full 50 percent only by claiming at their own full retirement age.9Social Security Administration. Benefits for Spouses A spouse who claims at 62 receives about 32.5 percent of your full benefit instead.
Survivor benefits follow a different schedule. A surviving spouse can start reduced survivor benefits at 60, or at 50 with a qualifying disability.10Social Security Administration. Survivors Benefits Waiting until their own full retirement age can pay up to 100 percent of what you were collecting or entitled to collect. At 60, the payment starts at 71.5 percent and rises with each month of delay.11Social Security Administration. What You Could Get From Survivor Benefits
One consequence often missed in planning: claiming early at a reduced amount can permanently lower your surviving spouse’s check. Take the 30 percent cut at 62 and the survivor benefit is based on that reduced number. Delaying to 70 doesn’t only raise your own payment; it also raises the floor for your spouse later.
Taxes on Your Benefits
Social Security benefits are not automatically tax-free. Federal tax depends on your “combined income,” which is adjusted gross income plus nontaxable interest plus half of your Social Security benefits. The thresholds have never been indexed to inflation, so they capture more retirees each year.
Single filers with combined income between $25,000 and $34,000 have up to 50 percent of benefits taxable, and above $34,000 up to 85 percent becomes taxable. For married couples filing jointly, the brackets are $32,000 to $44,000 and above $44,000.12Office of the Law Revision Counsel. 26 U.S.C. 86 – Social Security and Tier 1 Railroad Retirement Benefits Married filing separately while living with your spouse at any point in the year makes up to 85 percent taxable regardless of income.
“Up to 85 percent taxable” doesn’t mean an 85 percent tax rate. It means that portion of your benefit gets added to taxable income and taxed at your normal marginal rate. If you plan to work part-time or draw from retirement accounts alongside Social Security, the combined income test can pull more of your benefit onto the return than you expect. Some retirees file IRS Form W-4V to have taxes withheld directly from their Social Security payments.
If You Claim and Regret It
Start benefits and change your mind quickly, and Social Security lets you withdraw your application within 12 months of your first month of entitlement. You can do this only once.13Social Security Administration. 20 CFR 404.640 – Withdrawal of an Application Every dollar paid out on your record has to be returned, including any spousal benefits collected during that stretch.
Once the withdrawal is approved, Social Security treats the application as if it never existed, and you can refile later at a higher amount. After the 12-month window closes, the only tool left is suspending payments after you reach 67. Suspension lets delayed retirement credits build until you resume or turn 70, but it doesn’t undo the early-claiming reduction on months you already collected before 67.
