If you were born in 1966 and are asking when you can retire, the anchor date is 2033: that’s the year you turn 67, your Social Security full retirement age, and the point at which you can collect 100% of your calculated benefit.1Social Security Administration. 20 CFR 404.409 – What Is Full Retirement Age But retirement isn’t a single date. It’s a set of milestones spread across roughly sixteen years, each opening up a different piece of your income: penalty-free savings withdrawals at 59½, earliest Social Security at 62, Medicare at 65, full Social Security at 67, maximum Social Security at 70, and mandatory withdrawals from tax-deferred accounts starting at 75.
Your Key Retirement Ages at a Glance
- 2025–2026 (age 59½): penalty-free withdrawals from 401(k) and traditional IRA accounts begin.
- 2026 (age 60): the SECURE 2.0 “super” catch-up contribution of up to $11,250 becomes available and runs through age 63.
- 2028 (age 62): earliest Social Security retirement benefits, with a permanent 30% reduction.
- 2031 (age 65): Medicare eligibility begins.
- 2033 (age 67): full Social Security retirement age; 100% of your calculated benefit.
- 2036 (age 70): maximum Social Security benefit, 24% above your full retirement amount.
- 2041 (age 75): required minimum distributions from traditional retirement accounts must begin.
Full Retirement Age Is 67, in 2033
For anyone born in 1960 or later, Social Security sets full retirement age at 67.1Social Security Administration. 20 CFR 404.409 – What Is Full Retirement Age Because you were born in 1966, you reach that age in 2033, and at that point you receive your full calculated benefit with no reductions and no delayed-retirement bonuses.
The benefit itself is based on your highest 35 years of earnings, adjusted for wage inflation.2Social Security Administration. Social Security Benefit Amounts If you worked fewer than 35 years, zeros fill in the gaps and pull your average down. Every additional year of solid earnings between now and when you claim can replace a zero or a low year and raise your monthly check.
Claiming Early at 62 in 2028
You don’t have to wait for 67. The earliest you can start Social Security retirement benefits is 62, which for you means 2028.1Social Security Administration. 20 CFR 404.409 – What Is Full Retirement Age The cost is significant: claiming at 62 with a full retirement age of 67 permanently reduces your monthly benefit by 30%.3Social Security Administration. Retirement Age and Benefit Reduction That reduction stays in place for life, and every future cost-of-living adjustment is calculated off the reduced amount.
If you claim between 62 and 67, the reduction scales. The formula works out to roughly 6.67% per year for the first three years before full retirement age, then about 5% per year for any additional early years.4Social Security Administration. Early or Late Retirement So claiming at 64 costs you less than claiming at 62, but still results in a permanently smaller check than waiting until 67.
Working While Collecting Early
If you claim before 67 and keep working, Social Security applies an earnings test. In 2026, if you earn more than $24,480 from wages or self-employment, Social Security withholds $1 in benefits for every $2 over the limit. In the year you actually reach full retirement age, the threshold rises to $65,160 and the withholding drops to $1 for every $3 over.5Social Security Administration. Receiving Benefits While Working
The withheld money isn’t lost. Once you hit full retirement age, Social Security recalculates your benefit upward to account for the months payments were withheld. What doesn’t come back is the 30% early-filing reduction; that piece is permanent. Investment income, pensions, and annuities don’t count toward the earnings test. Only wages and net self-employment income do.5Social Security Administration. Receiving Benefits While Working
Delaying Past 67 to 70 in 2036
Every year you postpone Social Security past 67, your benefit grows by 8%.6Social Security Administration. Effect of Early or Delayed Retirement on Retirement Benefits These delayed retirement credits stop the month you turn 70.7Social Security Administration. 20 CFR 404.313 – What Are Delayed Retirement Credits and How Do They Increase My Old-Age Benefit Amount For you, that ceiling year is 2036. Waiting all the way from 67 to 70 means a 24% larger monthly payment than your full retirement amount, guaranteed and inflation-adjusted.
Whether delaying makes sense depends on your health, other income sources, and whether you can cover expenses without the check. The breakeven point, where total lifetime benefits from waiting exceed what you’d have collected by starting earlier, typically lands in the early 80s.
Getting to Your 401(k) and IRA Money
Your private retirement accounts follow IRS rules, not Social Security dates. Withdrawals from a 401(k), 403(b), or traditional IRA before age 59½ generally trigger a 10% early withdrawal penalty on top of ordinary income tax.8Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Born in 1966, you reach 59½ in 2025 or 2026 depending on your birth month. After that, the 10% penalty is gone, though income tax on traditional account withdrawals still applies.
The Rule of 55
If you leave your job in or after the year you turn 55, you can withdraw from that employer’s 401(k) or 403(b) without the 10% penalty, even before 59½. The exception is written into IRC Section 72(t)(2)(A)(v).9Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts It applies only to the plan of the employer you just left. Old 401(k)s at prior employers don’t qualify, and money you’ve already rolled into an IRA doesn’t either.
Roth IRA Withdrawals
Roth IRAs work differently. Your original contributions can come out tax-free and penalty-free at any age. Earnings require both that you’re at least 59½ and that the account has been open for at least five years, counted from January 1 of the tax year of your first Roth contribution. If your Roth was opened in 2020 or earlier, you’ll clear both hurdles once you hit 59½.
Catch-Up Contributions You Can Use Right Now
Turning 60 in 2026 opens a specific savings window. Under SECURE 2.0, workers aged 60 through 63 can make a “super” catch-up contribution of $11,250 to a 401(k) or 403(b), on top of the standard $24,500 employee limit, for a potential $35,750 in 2026.10Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Your plan has to allow the enhanced catch-up, so confirm with your employer before assuming you can use it.
For IRAs, the 2026 contribution limit is $7,500, with a $1,100 catch-up for anyone 50 or older, bringing the total to $8,600.10Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 The years right before retirement are your last real chance to load tax-advantaged accounts.
Medicare Starts at 65 in 2031
Medicare eligibility is set at 65, regardless of when your Social Security full retirement age falls.11Centers for Medicare & Medicaid Services. Original Medicare (Part A and B) Eligibility and Enrollment For you, that’s 2031. Your Initial Enrollment Period is a seven-month window: the three months before the month you turn 65, your birthday month, and the three months after.12Medicare. When Does Medicare Coverage Start Signing up in the three months before your birthday gets Part B coverage started the month you turn 65. Later sign-ups push the start date back.
Late Enrollment Penalties
Miss your Initial Enrollment Period without qualifying employer coverage, and Medicare adds a Part B late enrollment penalty of 10% for every full 12-month period you could have enrolled and didn’t. In 2026, the standard Part B premium is $202.90 per month.13Medicare. Avoid Late Enrollment Penalties A two-year delay adds about $40.58 per month, and that surcharge stays on your premium for as long as you have Part B.
The Healthcare Gap Before 65
If you retire before 65, you have a stretch to cover on your own. Retiring at 62 leaves a three-year gap. The usual options are COBRA continuation coverage from a former employer’s plan (up to 18 months, and you pay the full premium plus a 2% administrative fee), a spouse’s employer plan, or an Affordable Care Act marketplace plan.14U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers Budget for these premiums before you pick a retirement date; they’re one of the most underestimated costs of early retirement.
Required Withdrawals Kick In at 75, in 2041
Tax-deferred accounts don’t let you defer forever. Under the SECURE 2.0 Act, anyone born in 1960 or later must begin taking required minimum distributions at 75.15Congress.gov. Required Minimum Distribution (RMD) Rules for Original Owners of Retirement Accounts For you, that year is 2041. Your first RMD is due by April 1 of the year after you turn 75, so April 1, 2042 at the latest, and every subsequent RMD is due by December 31.
Skip an RMD and the IRS charges a 25% excise tax on the amount you should have withdrawn. Catch the mistake and take the distribution within two years and the penalty drops to 10%. Roth IRAs have no RMDs during the original owner’s lifetime, which is why Roth conversions before 75 have become a common planning move.
Taxes Follow You Into Retirement
Traditional 401(k) and traditional IRA withdrawals are taxed as ordinary income at your federal bracket. Roth withdrawals, if you meet the age and five-year rules, come out tax-free. That difference changes how much of your savings you actually get to spend.
Social Security benefits can also be taxed. The IRS uses “combined income,” which is adjusted gross income plus nontaxable interest plus half of your Social Security benefits. If that total tops $25,000 for a single filer or $32,000 for a married couple filing jointly, up to 50% of your benefits become taxable. Above $34,000 (single) or $44,000 (married filing jointly), up to 85% of benefits are taxable.16Social Security Administration. Income Taxes on Social Security Benefits A pension, 401(k) withdrawals, or investment income alongside Social Security will usually push a portion of your benefits into taxable territory. Some states tax Social Security; most don’t.
Spousal Benefits
If you’re married, you may be eligible for a spousal benefit worth up to 50% of your spouse’s full retirement amount, even with little or no work history of your own. Eligibility starts at 62 (or earlier if you’re caring for a qualifying child under 16). Claiming the spousal benefit before your own full retirement age of 67 reduces it, potentially to as little as 32.5% of your spouse’s benefit if you claim at 62.17Social Security Administration. Benefits for Spouses
If you qualify on both your own record and as a spouse, Social Security pays whichever is higher. You don’t collect both. Running the numbers on individual and spousal benefits, and coordinating when each spouse files, can add real money to lifetime household benefits.
How to Apply for Social Security
You can submit your application up to four months before you want benefits to start.18Social Security Administration.
