Social Security decisions can shape more than one person’s future.

Claiming early means a smaller monthly retirement benefit.

Your full retirement age (FRA) depends on your birth year. It is 67 for people born in 1960 or later. Retirement benefits can generally start at 62, with a reduction for starting before FRA. That early-claiming reduction generally continues; reaching FRA does not automatically restore the unreduced amount.

For someone with FRA 67, claiming at exactly 62 gives about 70% of the full retirement benefit. Starting at 67 gives 100%. Waiting past FRA earns delayed retirement credits until age 70—8% a year, credited monthly, for people born in 1943 or later. Waiting beyond 70 earns no additional delayed credits.

A larger monthly payment is not automatically the best choice for every household. Consider income needed now, health, other resources, work plans, and protection for a surviving spouse.

You can work and receive retirement benefits.

Before FRA, an earnings test can temporarily withhold benefits. These limits are for 2026 and change annually:

• Under FRA throughout the year: $1 withheld for every $2 earned above $24,480.
• The year you reach FRA: $1 withheld for every $3 above $65,160, counting only earnings before the month FRA is reached.
• From the month you reach FRA: no earnings-test limit.

The test generally counts wages and net self-employment earnings, not pensions, annuities, or investment income. A special monthly rule may help in the first retirement year. At FRA, SSA adjusts the benefit calculation for months withheld because of earnings; this is not an immediate lump-sum refund. Additional work can also increase benefits if it improves the earnings record used in the calculation.

The earnings test is different from income taxes or Medicare IRMAA. Disability benefits have separate work rules. Report work changes to SSA.

Spousal benefits: a living spouse’s work record

A spouse generally may qualify at 62 or older, or at any age while caring for the worker’s qualifying child under 16 or with a disability. The worker generally must be entitled to retirement or disability benefits. A one-year marriage requirement usually applies, with exceptions.

At your FRA, a spousal benefit can be up to 50% of the worker’s full-retirement-age benefit—not half of their larger age-70 payment. Starting early generally reduces the spousal amount. Spousal benefits do not earn delayed retirement credits after your FRA.

You do not receive your full retirement benefit plus a full spousal benefit. SSA pays your own benefit first and, if eligible, a spousal supplement. Early claiming can affect the combined result. For most current claimants, applying for retirement or spousal benefits means applying for both when eligible; you generally cannot take only spousal benefits while letting your own grow to 70.

Divorced? Ask about your former spouse’s record.

A marriage lasting at least 10 years may create eligibility for divorced-spouse benefits. Age, remarriage, your own benefit, and the former spouse’s eligibility matter. In some cases an ex-spouse need not have filed if you have been divorced at least two years. Ask SSA to check rather than assuming divorce erased all rights.

Survivor benefits: a different set of choices

A surviving spouse may qualify from age 60, or age 50–59 with a qualifying disability. Marriage generally must have lasted nine months, with exceptions; caring for the deceased worker’s eligible child can create other rights. A qualifying former spouse may also be eligible after a marriage of at least 10 years.

Remarriage before 60 generally affects eligibility, with different rules for disabled survivors; remarriage at 60 or later generally does not prevent survivor benefits on the prior spouse’s record. Let SSA review the specific marriage and disability history.

A survivor benefit may start around 71.5% and reach up to 100% at survivor FRA. Survivor FRA can differ from retirement FRA. The deceased worker’s claiming history and other rules affect the amount; do not assume it is simply their last deposit.

You generally do not keep both full checks after a spouse dies. Eligible people can sometimes claim survivor benefits first and switch to their own larger retirement benefit later, or use the reverse sequence. Unlike your own retirement benefit, survivor benefits do not increase for waiting past survivor FRA. The retirement earnings test can apply before retirement FRA.

A household may lose substantial income after a death while housing and other bills continue. Include that possibility in your insurance and retirement conversations.

Which disabilities can lead to Medicare before 65?

A diagnosis alone does not automatically qualify someone for SSDI or Medicare. Social Security Disability Insurance generally requires enough recent covered work and a medically supported impairment that prevents substantial gainful work, is expected to last at least 12 months, or is expected to result in death. SSA considers whether you can do past work or adjust to other work. This differs from a private disability policy’s definition.

Potentially qualifying impairments include severe musculoskeletal disorders, heart or lung disease, neurological disorders such as multiple sclerosis or Parkinson’s disease, certain cancers, serious mental disorders, immune-system disorders including HIV, and vision or hearing impairments. Severity, functional limits, treatment evidence, duration, and other rules matter. A condition need not exactly match a listed impairment to qualify under SSA’s full evaluation.

Why people say Medicare begins in “month 25”

For most people under 65 qualifying through Social Security disability benefits, Medicare begins after 24 months of benefit entitlement—normally the first day of the 25th entitlement month. The clock is not simply 24 months from diagnosis, application, approval, or the day the first check arrives. Retroactive entitlement can count, so an approval letter may establish an earlier start to the clock.

For example, if January 2025 is entitlement month 1, December 2026 is month 24 and Medicare generally starts January 1, 2027, assuming continuing eligibility and no applicable exception.

SSDI generally has a separate five-full-month cash-benefit waiting period before entitlement begins. It is not the same as Medicare’s 24-month period. Verify the entitlement and Medicare dates on your SSA notice. Most eligible disability beneficiaries are enrolled automatically in Parts A and B; review the welcome package, Part B premium, and drug-coverage choices before coverage starts.

Important exceptions and distinctions

• ALS: Medicare can start when entitlement to Social Security disability benefits begins, without the usual 24-month Medicare wait. Special rules also remove the SSDI cash waiting period for qualifying ALS claims.
• End-Stage Renal Disease (ESRD): permanent kidney failure requiring dialysis or a transplant has a separate Medicare pathway. Dialysis coverage usually starts in the fourth month, with earlier starts possible under specific home-dialysis training or transplant rules and other eligibility conditions.
• SSI: Supplemental Security Income alone does not start this Medicare clock. It may connect a person to Medicaid, subject to state rules.
• Private disability benefits: receiving a payment from an employer or individual disability policy does not itself qualify you for Medicare.

Some disabled adult children and disabled surviving spouses qualify through another person’s Social Security record. Ask SSA which entitlement rules apply. Do not assume private insurance, SSI, SSDI, and Medicare use identical definitions.
