When Should the Lower-Earning Spouse Claim Social Security?

For most couples, the lower-earning spouse should claim Social Security at or before full retirement age, while the higher-earning spouse delays as close to 70 as possible. That split works because the lower earner’s monthly check is partly built on the higher earner’s record, and the spousal portion stops growing once you hit full retirement age. Meanwhile, every month the higher earner waits directly raises the survivor benefit that will protect whichever spouse lives longer. The average retired worker collects about $2,071 per month in 2026, and the gap between a well-timed claim and a poorly timed one runs into hundreds of dollars every month for life.¹

Why the Lower Earner Claims First

The strategy rests on two features of the benefit formula that pull in opposite directions.

First, the spousal benefit caps at full retirement age. A spousal benefit tops out at 50 percent of the higher earner’s primary insurance amount, and it earns no delayed retirement credits.² Whatever the lower earner is going to get from the spousal top-off, they get it at full retirement age. Waiting longer adds nothing to that piece.

Second, the survivor benefit does keep growing. When one spouse dies, the survivor can step into up to 100 percent of what the deceased was receiving, including any delayed retirement credits the higher earner banked by waiting past full retirement age.³ So the higher earner’s delay pays off twice: a bigger check now, and a bigger check for the survivor later. The lower earner’s delay past full retirement age only grows their own work-record piece, which is small by definition.

Put those two facts together and the pattern falls out. The lower earner claims early enough to get cash flowing without permanently forfeiting much. The higher earner waits, because their delay does the real work of protecting the household.

How Full Retirement Age Sets the Baseline

Full retirement age anchors every reduction and every bonus in the system. For anyone born in 1960 or later, it’s 67. For those born between 1943 and 1954, it was 66, with a sliding scale for the birth years in between.⁴ Claim before that age and your monthly payment shrinks permanently. Claim after it, up to age 70, and it grows permanently. Both changes stick for life.

What Claiming Early Costs the Lower Earner

You can start your own retirement benefit as early as 62, but the discount is steep. For someone with a full retirement age of 67, claiming at 62 cuts the monthly payment by 30 percent. The reduction runs at 5/9 of one percent for each of the first 36 months before full retirement age, plus 5/12 of one percent for every additional month.³ A $1,000 full-retirement-age benefit becomes $700 at 62.⁵

Spousal benefits get hit harder. The spousal reduction runs at 25/36 of one percent for each of the first 36 months before full retirement age, then 5/12 of one percent for additional months. A lower-earning spouse with a full retirement age of 67 who claims at 62 sees the spousal benefit drop from 50 percent of the higher earner’s primary insurance amount to 32.5 percent.²

Social Security doesn’t make you pick between your own benefit and the spousal benefit. It pays your own first, then adds a supplement to lift you to the spousal amount if that’s higher. You get one combined check.⁶ And note the base: the spousal benefit is calculated on the higher earner’s primary insurance amount, not their actual check. If the higher earner delays to 70, those delayed retirement credits go into the higher earner’s own payment and into the survivor benefit later, but they do not raise the spousal benefit.²

The Higher Earner Has to File First

You generally cannot receive spousal benefits until the higher earner has filed for their own retirement. The regulation is direct: you’re entitled to spousal benefits only if the worker “is entitled to old-age or disability benefits.”⁷ So if the higher earner is still working at 66 and hasn’t claimed, the lower earner can only collect on their own record, even if the lower earner has already reached full retirement age.

This is the mechanics behind the staggered approach. The lower earner files first and collects a reduced benefit on their own record. Once the higher earner eventually files, the lower earner’s payment is recalculated to include the spousal supplement. The household gets some income early without permanently giving up the spousal top-off.

Deemed Filing Blocks the Old Workaround

Anyone born January 2, 1954, or later is subject to deemed filing. When you apply for either your retirement benefit or a spousal benefit, Social Security treats you as having filed for both, and you receive whichever produces the higher payment.⁸ You cannot file for just the spousal piece while letting your own benefit grow with delayed credits.

Survivor Benefits Do the Heavy Lifting

Survivor benefits are the reason the higher earner delays. When a spouse dies, the survivor can receive up to 100 percent of what the deceased spouse was receiving or would have been entitled to at death, including delayed retirement credits.³ If the higher earner delayed to 70 and locked in a $3,100 monthly benefit, the surviving lower earner steps into that $3,100. The household is going from two checks to one no matter what; making that remaining check as large as possible is the core payoff.

Surviving spouses can claim survivor benefits as early as age 60, or 50 with a qualifying disability.⁹ Claiming before full retirement age reduces the survivor amount by 19/40 of one percent per month, spread across the period from 60 to full retirement age.¹⁰ At 60, that reduction reaches roughly 28.5 percent.

One flexibility worth knowing: deemed filing does not apply to survivor benefits.⁸ A widowed spouse can take a reduced survivor benefit at 60 and switch to their own retirement benefit at 70 once delayed credits have maximized it, or claim their own reduced benefit early and switch to the full survivor benefit at full retirement age.¹¹

When Health and Longevity Change the Answer

Every claiming decision eventually turns on how long you live. The break-even point between claiming at 62 and waiting until 70 usually falls somewhere between 78 and 81, depending on your benefit amount and full retirement age.

For a lower earner, that math has a twist. Because the spousal piece caps at full retirement age, delaying past that point only grows your own work-record benefit, and if that benefit is small the extra dollars are small. A lower earner whose own benefit at 67 is $600 gains $144 per month by waiting to 70. That may not justify three years without a check. If the lower earner has health concerns pointing to a shorter life, claiming early makes even more sense. If both spouses are healthy and the higher earner has strong longevity prospects, protecting the survivor benefit matters most.

If the Lower Earner Keeps Working

Claiming early while still working triggers the retirement earnings test. In 2026, if you’re under full retirement age for the entire year, Social Security withholds $1 in benefits for every $2 you earn above $24,480. In the year you reach full retirement age, the threshold rises to $65,160 and withholding drops to $1 for every $3 above it.¹² Once you reach full retirement age, the earnings test disappears entirely.

Withheld money isn’t lost. After you reach full retirement age, Social Security recalculates your benefit to credit back the withheld months. But the cash-flow hit in the meantime is real. If most of your check would be withheld anyway, claiming early creates paperwork for little immediate gain.

Taxes and Medicare Take a Bite

Adding the lower earner’s benefit to household income can push Social Security into taxable territory. The IRS uses a “combined income” figure: half your household’s Social Security benefits, plus all other income, including tax-exempt interest.¹³ For married couples filing jointly:

Below $32,000: benefits are not taxed federally.
$32,000 to $44,000: up to 50 percent of benefits are taxable.
Above $44,000: up to 85 percent of benefits are taxable.

These thresholds have never been adjusted for inflation since they were set in 1983 and 1993.¹⁴ Most two-income households with any pension income, 401(k) withdrawals, or part-time earnings will land above $44,000. Timing the lower earner’s claim to a lower-income year, such as the gap between one spouse retiring and the other starting benefits, can soften the tax impact.

Medicare Part B premiums also come out of your Social Security check. The standard 2026 premium is $202.90 per month, with higher-income beneficiaries paying more.¹⁵ For a lower earner drawing a reduced $700 benefit at 62, that deduction starting at 65 eats nearly 29 percent of the gross. The net deposit is smaller than the benefit statement suggests.

When the Standard Advice Flips

The lower-earner-claims-first pattern fits most couples, but not all. If the lower earner has a strong enough work record that their own benefit at 70 would exceed the spousal amount, delaying makes more sense for them too. If both spouses have similar earnings histories, the “lower earner” label barely applies and each should evaluate independently. And if the higher earner has serious health issues, delaying their claim to build a survivor benefit they may not collect for long can lose more than it gains. The right answer depends on the gap between the two earnings records, both spouses’ health, household cash needs, and whether either spouse is still working.
