Claiming Social Security is one of the few retirement decisions that is both irreversible in practice and worth six figures over a lifetime. It is also easy to make by default, because someone stopped working and the money was there.

How it works
The basic mechanics
Your benefit is based on your highest 35 years of indexed earnings. Fewer than 35 years of earnings means zeros are averaged in, which is why a few additional working years can matter more for someone with an interrupted career than for someone with a continuous one.
Three ages matter:
- 62 is the earliest you can claim, at a permanently reduced amount.
- Full retirement age is 67 for anyone born in 1960 or later, and between 66 and 67 for those born earlier. This is where you receive your primary insurance amount with no adjustment.
- 70 is the last age at which delaying still increases the benefit. Waiting past 70 gains you nothing.
Between full retirement age and 70, delayed retirement credits increase the benefit for each month you wait. Before full retirement age, the reduction runs the other way.
What a break-even calculation leaves out
A break-even calculation asks at what age waiting pays off. That framing treats Social Security as an investment, which it is not.
Social Security is inflation-adjusted longevity insurance backed by the federal government. Nothing else in your portfolio does that job. The right question is not “will I come out ahead on average” but “what happens if I live to 95,” because that is the scenario that actually damages a retirement, and delaying is the cheapest available protection against it.
That said, delaying is not free. It can mean spending down other assets in the interim, and for someone in poor health or without other resources, claiming earlier can be entirely correct. The point is to make the decision deliberately.

Married couples: the decision is joint, not individual
This is where the decision is largest.
When one spouse dies, the survivor keeps the larger of the two benefits, not both. The household income drops, but the higher earner’s claiming decision permanently sets the survivor’s floor.
The practical implication: for a couple, the higher earner delaying can have value well beyond that person’s own lifetime, because it is simultaneously buying a larger survivor benefit for whoever lives longer. The lower earner’s claiming age matters much less.
Spousal benefits allow a lower-earning spouse to receive up to half of the higher earner’s primary insurance amount at full retirement age. Note that spousal benefits do not earn delayed retirement credits, so there is no reason for a spouse claiming purely on the spousal record to wait past full retirement age.
Divorced spouses married at least 10 years may claim on an ex-spouse’s record, and doing so does not affect the ex-spouse or their current spouse. This benefit goes unclaimed constantly because people assume the divorce ended it.
Working, taxes and claiming
If you keep working
Claiming before full retirement age while still working triggers the earnings test, which withholds part of your benefit above an annual earnings threshold. The withheld amount is not lost; your benefit is recalculated upward at full retirement age to account for it. But the cash flow effect in the interim surprises people.
The earnings test disappears at full retirement age. After that you can earn any amount with no reduction.
The Social Security Fairness Act, stated honestly
The Act, signed January 5, 2025, repealed the Windfall Elimination Provision and the Government Pension Offset for benefits payable from January 2024 forward.
If your employment had Social Security taxes withheld, this changes nothing for you. WEP and GPO only ever applied to pensions earned in non-covered employment. Most New Jersey public employees, including TPAF teachers and PERS county employees, are in covered employment and were never affected.
Check Box 4 of your W-2. If Social Security tax was withheld, there is no back payment coming and nothing to file.
Two groups genuinely benefit: people with a pension from non-covered public work in another state, and people with federal CSRS service.
New Jersey public employment is generally covered by Social Security. PERS and TPAF members pay Social Security tax on their public salary and earn credits in the ordinary way, so the state pension and the Social Security benefit are separate and neither reduces the other. If you spent your whole career in New Jersey public service, this section is unlikely to affect you. It matters if you also worked in a state whose public employees are outside Social Security, or if you have federal CSRS service.
Taxes on your benefit
Federally, up to 85% of Social Security can be included in taxable income, depending on your combined income. The thresholds are not indexed for inflation, which means more people cross them every year.
New Jersey does not tax Social Security at all. It is excluded from New Jersey gross income by statute, so there is no provisional income calculation and no level of other income at which any part of it becomes taxable. Railroad Retirement benefits are treated the same way.
This creates a planning point worth noticing: the federal treatment depends partly on your other income, so the order in which you draw from accounts can change how much of your Social Security is taxed.
Before you claim
- Create an account at ssa.gov and check your earnings record. Errors happen, and they are far easier to correct with old W-2s and pay stubs than without.
- Confirm you actually have 35 years of earnings, and see what a partial year would do.
- For couples, run the decision jointly and look explicitly at the survivor outcome.
- Coordinate with Medicare enrollment at 65, which has its own deadlines and its own penalties.

Earnings thresholds, tax thresholds, and benefit figures change; full retirement age depends on your year of birth. Confirm your own record and figures with the Social Security Administration at ssa.gov before acting.
Your own figures. We do not publish a Social Security calculator, because your my Social Security account estimates your benefit at every claiming age from your real earnings record. Our calculators cover the decisions around it.
This page is general. Your situation is not.
For a married couple the claiming decision is joint, and the survivor benefit outlives whichever of you claims first. It is worth working out together rather than one at a time. We can cover it in a short conversation, at no charge and with no obligation.
