The widow’s limit rule, known inside the Social Security Administration as RIB-LIM, caps a surviving spouse’s benefit when the deceased worker started collecting retirement benefits before full retirement age. The cap is the higher of two numbers: 82.5% of the worker’s full benefit (the primary insurance amount), or the reduced monthly check the worker was actually receiving.1Social Security Administration. Social Security Act 202 – Old-Age and Survivors Insurance Benefit Payments Whichever number is larger becomes the ceiling on what the survivor can be paid, no matter how long the survivor waits to file.
What the Cap Is Doing
Without this rule, a surviving spouse who files at their own full retirement age would receive 100% of the deceased worker’s primary insurance amount. The rule blocks that when the worker took a permanent reduction by filing early. Social Security won’t pay the survivor more than the worker was collecting, with one important cushion: the 82.5% floor.2Social Security Administration. POMS RS 00615.320 – Computation of Monthly Benefits Amounts
That floor matters most when the worker filed at 62, the earliest possible age. A worker with a 30% early-filing reduction is collecting only 70% of their full benefit, but their survivor is still guaranteed at least 82.5% of that full amount.3Social Security Administration. The Widow(er)’s Limit Provision of Social Security The wider the gap between what the worker took and what they earned, the more the floor does the work.
A Worked Example
A worker has a primary insurance amount of $2,400 and a full retirement age of 67. Filing at 62 knocks the benefit down 30% to $1,680 a month. The 82.5% floor is $2,400 × 0.825 = $1,980. Since $1,980 is higher than $1,680, the RIB-LIM cap is $1,980.3Social Security Administration. The Widow(er)’s Limit Provision of Social Security
Change the facts. Same worker, same $2,400 full benefit, but they filed at 65 instead of 62. That’s a 24-month reduction of about 13.34%, leaving the worker with roughly $2,080 a month. Now $2,080 beats the $1,980 floor, so the cap sits at $2,080. The later the worker filed, the higher the ceiling for the survivor.
Both figures in the comparison move with annual cost-of-living adjustments, so the cap isn’t frozen at the value it held on the day the worker died.5Social Security Administration. The Widow(er)’s Limit Provision of Social Security
When the Rule Applies to You
One question decides it: did the deceased worker start collecting retirement benefits before their full retirement age? If yes, the cap applies. If the worker waited until full retirement age or later, there’s no cap, and the survivor can be paid up to 100% of the worker’s benefit.4Social Security Administration. Social Security Act 202 – Old-Age and Survivors Insurance Benefit Payments
Because a large share of workers file at 62 to get income sooner, the widow’s limit rule is triggered in a lot of cases. Check the deceased worker’s Social Security statement or award letter for the month benefits started, and compare it to their full retirement age based on birth year.6Social Security Administration.

Your Own Filing Age Changes the Check
The cap is a ceiling. Your own filing age can put you well below it. A surviving spouse can file as early as 60, but doing so means a permanent reduction: about 71.5% of the full survivor amount at 60, climbing month by month to 100% at survivor full retirement age.7Social Security Administration. What You Could Get From Survivor Benefits
Note that full retirement age for survivor benefits runs on a different schedule than the one for retirement benefits. Survivors born from 1945 through 1956 have a survivor FRA of 66, rising for those born from 1957 through 1961, and reaching 67 for anyone born in 1962 or later.8Social Security Administration. Survivors Benefits
Social Security compares your age-reduced benefit to the RIB-LIM cap and pays whichever is lower. Back to the earlier example: cap of $1,980, worker’s full benefit of $2,400. A survivor filing at 60 gets 71.5% of $2,400, which is $1,716. That’s under the cap, so the survivor collects $1,716. Here the binding constraint isn’t the widow’s limit; it’s the survivor’s own early filing.
The Crossover Month
As you wait past 60, your age-reduced survivor amount climbs each month. At some point it reaches the RIB-LIM cap. After that month, waiting longer doesn’t add anything to your check, because the cap won’t rise with you. Delaying past that point costs you months of income for no additional benefit.
Social Security can calculate the exact crossover month for your case.9Social Security Administration. POMS GN 00204.045 – Determining the Month of Maximum Widow Insurance Benefits Ask for it directly when you apply. It’s the single most useful number in the whole calculation.
Switching Between Survivor and Your Own Retirement Benefit
If you have your own work record, the “deemed filing” rule that forces you to take all available benefits at once does not apply to survivor benefits.10Social Security Administration. Filing Rules for Retirement and Spouses Benefits You can claim one type of benefit now and switch to the other later.
A common sequence: claim the survivor benefit at 60 or a bit later (accepting the RIB-LIM cap and any age reduction), and leave your own retirement benefit alone so it keeps earning delayed retirement credits up to age 70. At 70, switch to your own retirement benefit if it’s now higher. The reverse can also work when your own record is strong: take a reduced retirement benefit at 62 and let the survivor benefit grow to its own peak at survivor FRA. Which order wins depends on the size of each benefit and how long you expect to live.
Divorce, Remarriage, and Disability
A surviving divorced spouse qualifies for the same benefits, cap and all, if the marriage lasted at least 10 years before the divorce.11Social Security Administration. Code of Federal Regulations 404.336 – How Do I Become Entitled to Widow’s or Widower’s Benefits as a Surviving Divorced Spouse Payments to a surviving divorced spouse don’t reduce what a current surviving spouse receives.
Remarrying before age 60 generally ends survivor eligibility, but if that later marriage ends through death, divorce, or annulment, eligibility can be restored. Remarrying at 60 or later doesn’t affect survivor benefits at all.12Social Security Administration. Will Remarrying Affect My Social Security Benefits?
A surviving spouse with a qualifying disability can file as early as age 50. The marriage must have lasted at least nine months before the worker’s death, and the survivor must not have remarried before age 50.13Social Security Administration. Who Can Get Survivor Benefits
If You’re Still Working
Survivors who keep working and haven’t reached full retirement age face an earnings test. In 2026, Social Security withholds $1 in benefits for every $2 earned above $24,480.14Social Security Administration. Receiving Benefits While Working In the year you reach full retirement age, the threshold rises to $65,160, and the withholding rate drops to $1 for every $3 above that.15Social Security Administration. Exempt Amounts Under the Earnings Test
The reduction is temporary. Once you hit full retirement age, the earnings test ends and the withheld amounts are added back into your monthly payment going forward. Still, in the early 60s, earning a few thousand over the threshold can noticeably cut your check for the year, so it’s worth mapping out before you file.
Applying
You can’t apply for survivor benefits online. Call Social Security at 1-800-772-1213 or visit a local office. Expect to provide proof of the worker’s death, your marriage certificate (or the final divorce decree for a surviving divorced spouse), proof of your age, and your most recent W-2 or self-employment tax return.16Social Security Administration. Form SSA-10 – Information You Need to Apply for Widow’s, Widower’s, or Surviving Divorced Spouse’s Benefits
Ask two things while you have the representative on the line. First: what is my crossover month, the point at which delaying my claim stops raising my payment because of the RIB-LIM cap? Second: does it make sense to take the survivor benefit now and switch to my own retirement benefit later, or the other way around? Both answers depend on numbers the agency already has on your record. Getting them before you file protects you from leaving months of benefits behind.
