Can I start Medicare at 65 but delay Social Security until later?

Yes. Medicare and Social Security are separate programs, and you can enroll in Medicare without claiming Social Security. Most working Ohioans past 65 enroll in Part A at 65 (free), keep their employer plan, and don't claim Social Security until their full retirement age or later. The two enrollment timelines are independent.

Will my Social Security benefit be reduced by my pension from OPERS or STRS Ohio?

Possibly — through the Government Pension Offset (GPO) for spousal benefits, or the Windfall Elimination Provision (WEP) for your own benefit. WEP affects workers who paid into Social Security and a non-covered pension (like OPERS or STRS Ohio for years when Social Security wasn't withheld). The Social Security Fairness Act, signed into law in January 2025, eliminated WEP and GPO going forward, with retroactive adjustments to affected beneficiaries. If your benefit was previously reduced under WEP/GPO, the SSA has been processing recalculations. Check ssa.gov for the latest on your situation.

How does claiming Social Security at 70 affect IRMAA on Medicare premiums?

IRMAA — the income-related monthly adjustment that raises Medicare Part B and Part D premiums for higher-income beneficiaries — is based on your modified adjusted gross income from two years prior. Social Security benefits don't directly count as IRMAA income, but the taxable portion does. Combining delayed Social Security with traditional IRA withdrawals or Roth conversions could push you into higher IRMAA brackets. Coordinate with your tax advisor.

Should I retire from my Ohio pension before or after starting Social Security?

There's no universal answer. Each Ohio pension (OPERS, STRS Ohio, SERS, OP&F, HPRS) has its own retirement timing rules, age-and-service requirements, and benefit structures. Some retirees can retire from the pension at 55-60 with sufficient service credit and bridge to Social Security at 67 or 70 using pension income, HSA savings, and other assets. The pension's own rules about retiree health coverage (HRA, stipend, or group plan) also factor in. Work with a financial planner who knows Ohio pension specifics.

If I take Social Security at 62, can I switch to delayed credits later?

Generally no — once you claim Social Security, you're locked in at that benefit level (with annual cost-of-living adjustments). The exception: within 12 months of starting benefits, you can withdraw your application (Form SSA-521), repay everything you've received, and re-claim later. After 12 months, the only adjustment available is to voluntarily suspend benefits at FRA to start earning delayed retirement credits again — but you forfeit benefits during the suspension.

How does retiring affect my Medicare premiums and IRMAA?

Medicare Part B and Part D premiums are based on your modified adjusted gross income from two years prior. If you retired in 2024, your 2026 IRMAA is based on your 2024 income — which likely included your final working year's salary. As your post-retirement income drops, IRMAA can be reduced via the SSA-44 form (Medicare Income-Related Monthly Adjustment Amount — Life-Changing Event), which lets you report a major life event like retirement, work reduction, or income loss for a recalculation.

Three decisions, three timelines

Most Ohioans approaching retirement think of "retirement" as a single event. In federal benefits terms, it's three:

When you enroll in Medicare — Initial Enrollment Period around 65, or Special Enrollment Period after employer coverage ends.
When you claim Social Security — any time from 62 to 70, with different monthly benefit amounts.
When you actually stop working — your retirement date as the employer sees it.

These can happen on the same date, weeks apart, months apart, or years apart. The optimal sequencing depends on your finances, your employer's health coverage, your Social Security benefit amount, and what you want to do with your time.

Medicare at 65 (almost always)

Medicare eligibility starts at 65 (with rare exceptions for those qualifying through disability before 65). Your Initial Enrollment Period is the 7-month window straddling your 65th birthday month — 3 months before, the birthday month itself, and 3 months after.

For most Ohioans, the right move is to enroll in Part A at 65:

It's free for nearly everyone with 40 quarters of Medicare-covered work history.
It adds hospital coverage to whatever else you have.
There's no reason to skip it — the only exception is if you're contributing to an HSA through an HDHP, in which case Part A enrollment disqualifies you.

The Part B decision is more nuanced and depends on whether you have creditable employer coverage and how the math works out. See our employer coordination guide for the 20-employee rule and the case for delaying Part B.

Full Retirement Age for Social Security

Social Security's "Full Retirement Age" (FRA) is the age at which you get 100% of your earned Social Security benefit. It's based on your birth year:

Birth year	Full Retirement Age
1943 – 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 or later	67

So if you were born in 1960 or later — which includes everyone currently turning 66 in 2026 — your FRA is 67. Claiming earlier permanently reduces your benefit; claiming later (up to 70) permanently increases it.

Specifically:

Claiming at 62: roughly 70% of your FRA benefit (a 30% permanent reduction).
Claiming at 67 (FRA for 1960+): 100% of your FRA benefit.
Claiming at 70: roughly 124% of your FRA benefit (a 24% permanent increase).

Delayed Retirement Credits: 67 to 70

Each month you delay claiming Social Security beyond your FRA, your eventual benefit grows by 2/3 of 1% — roughly 8% per year. This continues until age 70. After 70, additional delay produces no further benefit increase.

The 8% annual growth is risk-free, government-backed, and applies to your monthly benefit for life. Few investments match that risk-adjusted return for someone in their late 60s. For Ohioans with sufficient assets to cover living expenses between FRA and 70, delaying Social Security to 70 is often the single most valuable financial decision they make.

The break-even math: if you delay from 67 to 70, you give up 36 months of benefits. The increased benefit at 70 starts paying you 24% more per month. You "break even" around age 82-83 — meaning if you live past 82, delayed claiming wins; if you don't, claiming at 67 wins. Life expectancy for someone reaching age 65 in good health is well into the 80s, so the odds favor delayed claiming for most healthy Ohioans.

Delayed claiming and spousal benefits

Spousal Social Security benefits are based on the higher earner's FRA benefit, not their delayed-credit benefit. So delaying your own claim past FRA increases your own monthly benefit, but it doesn't increase the spousal benefit your spouse receives if their own work record produces a smaller benefit. Couples with a large earnings gap usually have the higher earner delay to 70 (which also creates the largest survivor benefit) and the lower earner claim at FRA or before.

Retiring at 66 vs. 67 vs. 68 vs. 70

Four common Ohio retirement-age scenarios:

Retire at 66 (early FRA):

Already on Medicare since 65 (with or without Part B, depending on employer coverage).
Below FRA — claiming Social Security at 66 means a permanent reduction (small, since FRA is 67).
If you have employer coverage from a 20+ employer, you might continue working and delay both Social Security and Part B another year or two.

Retire at 67 (FRA):

Medicare typically already in place from 65.
Social Security at FRA gives you 100% of your earned benefit, no penalty, no delayed credit.
For most Ohioans this is the conservative "normal" retirement timing.

Retire at 68 or 69:

You've earned 1-2 years of delayed retirement credits — 8%-16% higher Social Security benefit.
If you've been HSA-contributing past 65, you've added 3-4 years of HSA savings.
Continued earned income may keep you in higher tax brackets, partially offsetting the delayed-claiming gains.

Retire at 70:

Maximum delayed retirement credits — Social Security benefit is 124% of FRA amount.
If you've been working past 65, you may have added significant 401(k)/403(b) and HSA savings.
You must take Required Minimum Distributions (RMDs) from traditional IRAs and 401(k)s starting at age 73 (under SECURE 2.0), so the window between retirement at 70 and RMDs at 73 is brief.

Earnings test if you claim before FRA

If you claim Social Security before your Full Retirement Age and continue to earn income, the SSA earnings test can temporarily reduce your benefit:

Before FRA, calendar year before reaching FRA: For each $2 you earn over $23,400 (2026 limit, indexed annually), $1 is withheld from your Social Security benefit.
The year you reach FRA, but only earnings before FRA month: For each $3 you earn over $62,160 (2026 limit), $1 is withheld.
After you reach FRA: No earnings test. You can earn unlimited income without affecting Social Security benefits.

Withheld benefits aren't lost — they're added back to your monthly benefit after you reach FRA. But the cash-flow disruption matters if you're planning on Social Security for ongoing expenses while still working. Most Ohioans who claim before FRA and continue working should run the earnings test math before deciding.

Ohio cost-of-living context

Ohio's cost-of-living is moderate — generally below national average in most counties. This affects retirement timing decisions in a few ways:

Your Social Security benefit goes further in Ohio than in higher-cost states (California, New York, Massachusetts). The break-even math on delayed claiming may favor claiming earlier if your needs are modest and Ohio cost-of-living gives you cushion.
Property taxes in Ohio vary significantly — Cuyahoga County is among the highest in the country; Vinton, Pike, and Holmes counties are among the lowest. Where you retire affects your fixed-cost calculation.
Health care costs in Ohio's major metros (Cleveland, Columbus, Cincinnati, Dayton, Toledo, Akron) are competitive — Cleveland Clinic and OSU Wexner are nationally ranked, and Medicare Advantage premiums tend to be lower than in coastal states.
State income tax on retirement income — Ohio taxes Social Security benefits at the state level (with some senior exemptions and credits), as well as pension income, IRA distributions, and 401(k) withdrawals. Federal tax on Social Security depends on combined income; up to 85% can be taxable at higher income levels.

For most Ohioans, the moderate cost-of-living means retirement at FRA (67 for those born 1960+) is comfortable. Delayed claiming to 70 produces higher lifetime benefits, especially for the higher earner in a couple who wants to maximize survivor benefits.
