Social Security claiming alongside your FERS annuity
Your Social Security claiming age is a separate choice from when you retire, and you can claim any time from 62 to 70. Claiming early means a smaller monthly check for life; waiting means a larger one. The decision also interacts with your FERS pension and the SRS.

When can you claim Social Security?
You can start Social Security any time between ages 62 and 70, and that’s separate from when you retire from federal service. You could retire at your Minimum Retirement Age and still wait years to claim Social Security.
Three dates often get confused. Your retirement date is when you leave your job, and your Special Retirement Supplement bridges you to 62. Your Social Security claiming age is a third, independent choice.
The claiming age sets your benefit for life. The month you first claim fixes your monthly amount, with only inflation adjustments after that. It’s one of the few retirement decisions that follows you for the rest of your life.
Three things shape the choice: how the age changes your check, how it fits with the SRS, and what you’re weighing it against. None of them points to one age for everyone, so this lesson names no age.
Quick answers
When can I claim Social Security?
You can claim Social Security retirement benefits any time from age 62 to age 70. The age you choose is separate from when you retire from your federal job. Claiming earlier gives you a smaller monthly benefit for life; waiting gives you a larger one. There’s no gain from waiting past 70, when the increases stop.
Is my Social Security claiming age the same as my retirement date?
No. They’re independent choices, so you can retire from federal service at your MRA and delay Social Security for years. In the meantime, you live on your FERS pension, the Special Retirement Supplement, and your TSP. The claiming age only sets when Social Security starts and how large the monthly benefit is (the pension and supplement run on their own clocks).
How does your claiming age change your benefit?
Your claiming age changes your monthly benefit a lot. Full retirement age (FRA) is the anchor: claim then and you get 100% of your benefit. For people born in 1960 or later, FRA is 67.
Claiming early cuts the benefit. Claim at 62 with an FRA of 67, and your benefit is reduced about 30%, for life. The reduction shrinks the closer you claim to your FRA.
Waiting past FRA raises it. Delayed retirement credits add about 8% for each year you wait, up to age 70. At 70, the benefit is about 124% of your FRA amount, and after that the credits stop.
So the spread is wide: between 62 and 70, your monthly benefit can nearly double (70% of the full amount at one end, 124% at the other). The chart shows the benefit at each age as a share of your full retirement amount.
Your benefit by claiming age
A bar chart of the Social Security benefit at each claiming age from 62 to 70, as a share of the full retirement age benefit, for someone whose full retirement age is 67. Claiming at 62 gives about 70%, a 30% reduction. The age 67 bar is the full benefit reference. Claiming at 70 gives about 124%, a 24% increase. Each year of waiting adds roughly 8%.
Quick answers
How much does claiming early reduce my Social Security?
Claiming before your full retirement age permanently reduces your monthly benefit. With a full retirement age of 67, claiming at 62 cuts it by about 30%. Claim at 65, and the reduction is smaller, around 13%. The reduction is set when you first claim and lasts for life, apart from inflation adjustments.
How much does waiting past full retirement age add?
Waiting past your full retirement age earns delayed retirement credits, about 8% for each year. With a full retirement age of 67, waiting until 70 raises your benefit to about 124% of the full amount. The credits stop at 70, so there’s no gain from waiting beyond that, and the higher amount then lasts for life.
What is full retirement age for FERS employees?
Full retirement age is a Social Security term, not a FERS one, and your birth year sets it. For anyone born in 1960 or later it’s 67, the age at which you receive 100% of your benefit, with no early reduction and no delayed credit. Your FERS retirement eligibility is separate and uses different ages.
How does Social Security interact with the SRS?
The Special Retirement Supplement and Social Security are connected but separate: the SRS bridges you from retirement to 62, then stops. At 62, you decide on your own whether to claim Social Security or keep waiting.
The SRS ends at 62 no matter what. Your supplement stops at the end of the month you turn 62, whether or not you apply for Social Security. It doesn’t roll over into your Social Security check.
The SRS isn’t your Social Security. It approximates the Social Security you earned from FERS service, but OPM pays it. Claiming or delaying Social Security doesn’t change your SRS, and the SRS doesn’t change your Social Security benefit either.
So a gap can open at 62. If your SRS ends and you wait to claim Social Security, you’ll cover that stretch from your pension and savings. The SRS earnings test can also reduce the supplement before 62 if you work.
Quick answers
Does the Special Retirement Supplement turn into Social Security at 62?
No. The supplement simply stops at the end of the month you turn 62. It doesn’t convert into your Social Security benefit or get added to it. At 62, you separately decide whether to claim Social Security. The supplement was only a bridge from your retirement to age 62, standing in for the Social Security part of your FERS benefit.
If my SRS stops at 62, do I have to claim Social Security then?
No. The supplement ends at 62 regardless, but you aren’t required to claim Social Security at 62. Many federal retirees let the supplement stop and delay Social Security to grow the benefit, covering the gap with their FERS pension and TSP. Waiting raises your monthly Social Security for the rest of your life.
Does claiming Social Security early affect my FERS pension or SRS?
No. Your FERS pension and the supplement are computed separately from Social Security. Claiming Social Security early or late doesn’t change your pension, and it doesn’t change the supplement you already received. The three income sources are calculated on their own rules, even though they overlap in time.
Does your FERS pension reduce your Social Security?
No. Your FERS pension doesn’t reduce your Social Security. FERS work is covered by Social Security, so you pay into the system and earn benefits like any other worker. The old penalties for government pensions don’t apply to FERS.
Those penalties were WEP and GPO. The Windfall Elimination Provision and Government Pension Offset once reduced Social Security for some retirees. They hit people with a pension from work not covered by Social Security, mainly CSRS employees. FERS was never the target, because FERS is covered.
And they’re now repealed: the Social Security Fairness Act ended WEP and GPO for benefits payable starting January 2024. So even retirees who were affected, like CSRS annuitants, no longer face the reduction.
In simple terms, your pension and your Social Security stand on their own. Neither one shrinks the other, and the repeal removes any lingering worry about an offset.
Quick answers
Does a FERS pension reduce your Social Security benefit?
No. FERS employees pay Social Security taxes, so their federal work is covered and counts toward Social Security like any job. The Windfall Elimination Provision and Government Pension Offset, which reduced benefits for non-covered pensions, never applied to FERS. The Social Security Fairness Act also repealed those provisions, so they no longer reduce anyone’s benefit.
What was the difference between FERS and CSRS for Social Security?
FERS is covered by Social Security, and FERS employees pay into it and earn benefits directly. CSRS wasn’t covered, so CSRS employees didn’t pay Social Security on that work. The old WEP and GPO rules could then reduce any Social Security they earned elsewhere. The Social Security Fairness Act has since repealed those rules for everyone.
Do WEP and GPO still exist?
No. The Social Security Fairness Act repealed both the Windfall Elimination Provision and the Government Pension Offset. The change applies to benefits payable for January 2024 and later. For FERS retirees, this is mostly moot, since FERS was always covered by Social Security. With that said, it fully removes the offset for affected CSRS retirees and others.
What if you claim while still working?
If you claim Social Security before your full retirement age and keep working, an earnings test can hold back part of your benefit. Social Security withholds some benefits if your earnings top an annual limit. The held-back money isn’t lost.
The test only applies before FRA. If you’re under full retirement age for the whole year, Social Security holds back 1 dollar for every 2 you earn above the limit. In the year you reach FRA, the holdback is smaller, and from your FRA on there’s no earnings test at all.
Withheld benefits come back later, because at your full retirement age Social Security recomputes your benefit to credit the months it withheld. So the earnings test delays benefits rather than erasing them. Keep in mind that only earned wages count, not your pension or TSP withdrawals.
Taxes are a separate issue. Depending on your total income, up to 85% of your Social Security can be subject to federal income tax. Your FERS pension and TSP withdrawals add to the income that decides how much is taxed.
Quick answers
Does working reduce my Social Security if I claim early?
It can, temporarily. If you claim before full retirement age and earn above the annual limit, Social Security holds back part of your benefit. The holdback is 1 dollar for every 2 you earn over the limit, and only wages from work count, not your FERS pension or TSP withdrawals. After your full retirement age, the test no longer applies, and the withheld benefits are credited back.
Are the withheld benefits from the earnings test lost?
No. The earnings test withholds benefits, but it doesn’t erase them. When you reach full retirement age, Social Security recalculates your benefit to give credit for the months it held back, and your monthly amount goes up to reflect them. So the test mainly shifts the timing of the income, not the total.
Does the earnings test punish me for retiring mid-year?
Usually not, thanks to a special rule for your first year. Social Security can pay you a full benefit for any whole month it considers you retired, no matter what you earned earlier in the year. A federal employee who works most of the year and then retires can still collect for the remaining months. From the second year on, only the annual limit applies.
Does my lump-sum annual leave payout count against the earnings test?
It shouldn’t, but your payroll office has to say so. A leave payout is a special wage payment: you earned it in earlier years even though it lands after you separate. Payroll reports it on form SSA-131 so that it isn’t counted in the year you receive it. This matters most if you retire late in the year and claim at the same time, since the payout can take several months and often lands in the next calendar year.
Is my Social Security benefit taxed?
It can be. Depending on your combined income, up to 85% of your Social Security benefit may be subject to federal income tax. Your FERS pension and TSP withdrawals count toward the income that determines this. Some states tax Social Security and others don’t, and a tax professional can help you estimate the effect for your situation.
How to weigh the claiming decision
Your health, your other income, and your spouse all bear on the claiming age, which is why no one age suits everyone. Claiming early gives you smaller checks sooner, while waiting gives you larger checks later if you can bridge the gap. The factors below are what you’d weigh between the two.
A few factors carry the most weight. Your expected longevity, your need for income before the larger benefit starts, and whether a spouse will rely on your benefit all pull the decision in different directions.

Then confirm your estimate with your personalized record at the Social Security Administration.
- Longevity. Waiting pays off more the longer you expect to live, since the larger benefit lasts for life.
- Income gap. Delaying means covering the years from your SRS ending until your benefit starts, from your pension and TSP.
- Spouse. A higher benefit can raise the survivor benefit your spouse receives if you die first.
Quick answers
What is the best age to claim Social Security?
No one age is best for everyone. Claiming at 62 gives smaller payments that start sooner, while waiting toward 70 gives larger payments for life, if you can cover the years in between. The main factors are your expected longevity, your need for income now, and whether a spouse will depend on your benefit. Those factors decide it, so this lesson doesn’t name an age.
How does my claiming age affect my spouse?
A higher benefit can mean a higher survivor benefit. If you die first, a surviving spouse may step up to your Social Security amount if it’s larger than their own. Claiming later, which raises your benefit, can therefore protect your spouse as well as you. This is one reason couples often coordinate their two claiming decisions.
Should I claim Social Security as soon as my SRS ends?
Not necessarily. The supplement ends at 62, but you can still delay Social Security to grow the benefit. The question is whether your pension and savings can cover the gap until you claim. That turns on your income needs and your outlook on longevity, so this lesson lays out the trade-off without naming a date.
