Social Security for Physicians: How a Late Career Start Shapes Your Benefit

You spent your twenties in lecture halls, call rooms, and on night shifts. While college friends were building careers and paying into Social Security on full salaries, you were paying tuition. By the time your first attending paycheck arrived, you may have been 31, 33, or older. That timing shapes a lot of your financial life, and Social Security is one of the places it shows up in ways that aren't obvious.

Social Security can be easy to overlook when you're planning for retirement. The benefit can look small next to a 401(k) or 403(b) balance, and the formula looks intimidating. Still, it's an inflation-adjusted income stream that lasts as long as you do, and for a married couple it can last as long as the longer-lived spouse. That makes it worth understanding as one piece of your broader retirement planning as a physician.

This article walks through how your benefit is calculated, how a late career start shows up in the formula, how the wage-base cap interacts with an attending income, what changes between claiming at 62, full retirement age, and 70, and how spousal and survivor benefits work. That last piece carries extra weight if your household runs mostly on one income, a setup with its own set of money conversations when one spouse earns most of the income.

How Social Security Calculates Your Retirement Benefit

The calculation has three steps, and the Social Security regulations lay out how average indexed monthly earnings are computed.

• Indexing your earnings. Each year's earnings are adjusted for growth in the national average wage, up through the year you turn 60. A resident salary from 15 years ago gets scaled up to reflect how much wages have grown since then. Earnings after 60 count at face value.
• Averaging your top 35 years. Social Security takes your 35 highest indexed years, adds them up, and divides by 420 (the number of months in 35 years). The result is your average indexed monthly earnings, usually shortened to AIME. If you have fewer than 35 years of earnings, the missing years count as zeros.
• Applying the benefit formula. Your AIME runs through a progressive formula that produces your primary insurance amount, or PIA. That's the monthly benefit you'd receive if you claimed at your full retirement age.

The third step is where physician incomes get interesting. For people first eligible in 2026, the benefit formula bend points work like this: 90 percent of the first $1,286 of AIME, plus 32 percent of AIME between $1,286 and $7,749, plus 15 percent of AIME above $7,749. The formula is weighted to replace a larger share of income for lower earners. As your earnings history climbs, each additional dollar of AIME adds less to your benefit.

There's also a ceiling on how much of your income counts at all. Social Security tax and benefit credit apply only up to the contribution and benefit base, which is $184,500 for 2026. Earnings above that line aren't taxed for Social Security and don't raise your future benefit.

How a Late Career Start Shows Up in the 35-Year Average

Here's the part that speaks to the training path. A common physician timeline includes a few years of modest earnings in college or before medical school, four years of medical school with little or no wage income, then three to seven years of residency and fellowship before attending life starts. If you finish training at 32 and work full time until 60, you'd have 28 attending years. Add your residency and fellowship years and you may land close to 35, or a few years short of it.

Residency and Fellowship Years Usually Count

Full-time residents generally don't qualify for the student exception to Social Security tax under the Treasury regulations, so resident and fellow salaries are typically treated as wages subject to that tax. After wage indexing, a resident salary from years ago may look somewhat larger than it did on your paystub, though it usually stays well below what you earn as an attending. Those years still count toward your 35, and they matter more if your attending career ends up on the shorter side.

Zero Years and Low Years

If your record has fewer than 35 years with earnings, Social Security fills the gaps with zeros. A zero pulls your average down the same way a low year does, only more. Each year of attending-level earnings you add later can push one of those zeros or low years out of your top 35. That's why an extra year or two of work late in a career, even part time, may nudge the benefit up for someone with a shorter earnings record. For someone who already has 35 strong years, the same extra year may change very little.

What This Often Looks Like in Practice

Picture two hypothetical physicians who each earn above the wage base throughout attending life. One finished training at 30. The other finished at 36 after a long surgical fellowship. Both plan to stop working at 62. The first has 32 capped attending years plus residency. The second has 26 capped years plus a longer stretch of training-level pay, and possibly a zero year or two from medical school.

The second physician's PIA will usually come out lower. The gap is real, but the progressive formula softens it. At a physician-level AIME, the marginal dollars sit in the 15 percent tier of the formula, so swapping a few capped years for training years shrinks the benefit by less than you might guess from the earnings difference alone.

The Wage-Base Cap and Your Attending Income

For an attending earning $350,000 or $600,000, the wage-base cap does a lot of the work. Once your earnings pass $184,500 in 2026, the extra income doesn't raise your benefit. A hospitalist earning $300,000 and a surgeon earning $800,000 in the same year get the same Social Security credit for that year.

That has a few practical consequences worth knowing about:

• Your attending years tend to look alike on your record. Once you're at the cap, a raise or a large RVU bonus usually doesn't move your future benefit.
• Your Social Security tax has a ceiling too. With a single employer, you'll see the 6.2 percent Social Security withholding stop once your wages for the year pass the cap. If you work for two employers in the same year and too much Social Security tax is withheld, you may be able to claim the excess as a credit on your income tax return, as the IRS explains in its topic on excess Social Security tax withheld.
• Medicare tax is different. The Medicare portion of payroll tax has no wage cap, and an additional 0.9 percent Medicare tax applies to wages above certain income thresholds. So you'll keep seeing Medicare withholding all year.
• 1099 income can count. Self-employment income from locums work or moonlighting is subject to Social Security tax up to the contribution and benefit base, reduced by any W-2 wages you were paid that year. If your W-2 wages already reach the cap, additional self-employment income isn't subject to the Social Security portion of self-employment tax.

To put rough numbers on it: a single year at the cap adds about $439 to your AIME when it replaces a zero year ($184,500 divided by 420 months). At the 15 percent tier of the formula, that works out to roughly $66 per month of PIA in today's dollars, before cost-of-living adjustments and any claiming-age changes. Replacing a low-earning year instead of a zero adds less. These figures are illustrative, not a projection of your benefit. They show the shape of it: each extra year counts, and at a physician income each one adds a modest amount.

Claiming at 62, Full Retirement Age, or 70

Your full retirement age (FRA) depends on your birth year. For anyone born in 1960 or later, it's 67. You can start benefits as early as 62 with a reduction, or wait past 67 and earn delayed retirement credits of 2/3 of 1 percent per month, which works out to 8 percent per year, until 70. Credits are earned only through the month you turn 70. The Social Security regulation on delayed retirement credits sets out the rate by birth year.

The table below shows what each claiming age means for someone born in 1960 or later. The middle column is your own benefit as a share of your PIA. The right column is the most a spouse can receive on your record if the spouse starts the spousal benefit at that same age.

Two details stand out. The spread between the earliest and latest claiming ages is wide: a benefit started at 70 is about 77 percent larger than one started at 62 (124 divided by 70). And the spousal column stops growing at full retirement age. Delayed retirement credits raise your own benefit, but they don't raise the spousal benefit your spouse can draw on your record.

The Trade-Offs That Come Up in This Decision

• Longevity. Claiming later means fewer checks, each one larger. In a simple comparison that ignores taxes and investment growth, cumulative benefits from claiming at 70 catch up to claiming at 62 around age 80, and catch up to claiming at 67 around age 82 or 83. Your own health and family history shape how you weigh those ages.
• How you'd fund the gap years. If you stop clinical work at 60 and wait until 70 to claim, you're drawing more from savings for a decade. That's a cash-flow question as much as a Social Security one.
• Inflation adjustments. Benefits receive annual cost-of-living adjustments (the increase announced for 2027 was 3.6 percent). A larger starting benefit means each future adjustment applies to a larger base.
• The earnings test if you're still working. If you claim before full retirement age and keep earning above an annual limit, Social Security may withhold some or all of your benefits for that year. The earnings test applies only to months before you reach full retirement age.
• Your spouse's situation. In a married household, your claiming age also helps set the survivor benefit, which the next section covers.

Spousal Benefits in a Single-Earner Physician Household

If you're the primary earner and your spouse stepped back from paid work to raise kids or run the household, two provisions matter a great deal: the spousal benefit and the survivor benefit. They work differently, and they're easy to mix up.

How the Spousal Benefit Works

According to the Social Security regulation on spouse's benefits, a spouse's monthly benefit is one-half of the worker's PIA when the spouse claims at their own full retirement age. Claiming earlier reduces it, down to 32.5 percent at 62 for someone with a full retirement age of 67. A few rules shape how this plays out:

• If your spouse is eligible for both a spousal benefit and their own retirement benefit, a rule called deemed filing treats an application for one as an application for the other, as set out in the Social Security Act provision on deemed filing.
• The spousal benefit doesn't earn delayed retirement credits. Once your spouse reaches full retirement age, waiting longer doesn't raise it.
• The spousal amount is based on your PIA, not on the benefit you actually receive. If you delay to 70, your own check grows, but the spousal maximum stays at half of your PIA.

Social Security is one piece of retirement income for a non-earning spouse. A spousal IRA is a separate mechanism that lets a spouse without earned income build savings in an account in their own name, and the two often come up in the same planning conversation.

The Survivor Benefit and Why Your Claiming Age Reaches Past Your Own Lifetime

When one spouse dies, the surviving spouse keeps the larger of the two benefits, not both. The survivor benefit is equal to the deceased worker's primary insurance amount, and it can increase if the worker earned delayed retirement credits. Under the regulations, a surviving spouse who claims before their own full retirement age receives a reduced amount, and if the worker claimed early, the survivor amount may be reduced as well.

This is the piece that changes the claiming picture for a single-earner household. If you're the higher earner and you wait until 70, that larger check may keep going for your spouse after you're gone. Your claiming age is partly a decision about the longer of two lifetimes, not only your own. That's why the ages and health of both spouses, and the age gap between you, tend to come up early when you're weighing when to claim.

Here's what that can sound like at the kitchen table: "I'm not sure I'll live past 80, so why wait?" It's a fair question. In a household where your spouse is younger, or where longevity runs in your spouse's family, the answer may look different once the survivor benefit is part of the math.

How Claiming Fits With the Rest of Your Retirement Plan

Social Security timing doesn't sit on its own. It connects to when you stop clinical work, how you draw from your accounts, and how your taxes look year by year. If you retire at 60 and wait until 70 to claim, the years in between may have lower taxable income than your working years. That's one reason those years sometimes become a window for Roth conversions, which shift money from pre-tax accounts into Roth accounts while your bracket is lower.

Social Security benefits can be taxable, too. Depending on your other income, up to 85 percent of your benefits may be included in federal taxable income, a limit set in Section 86 of the Internal Revenue Code. In a physician household with sizable pre-tax retirement accounts, later withdrawals and required minimum distributions (the IRS-mandated withdrawals from pre-tax retirement accounts) can push more of your benefit into the taxable range. How those pieces fit together depends on your specific accounts and timeline, and it's worth reviewing with a CFP® professional or tax professional who can see your full picture.

These timing questions tend to pile up near the end of a career. Our pre-retirement checklist for the five years before you stop working covers Social Security alongside health coverage, withdrawal order, and the other decisions that cluster in that stretch.

A Note on the Program's Long-Term Financing

You've probably heard concerns about the long-term financing of the Social Security trust funds. Policy changes are possible, and nobody can say what they'll look like. Some households choose to run their retirement plan with more than one Social Security assumption, including a reduced one, so the plan doesn't lean on a single number.

Checking Your Own Earnings Record

Your benefit is computed from your earnings record, so the record is worth checking against your own W-2s and tax returns. With a physician's history in mind, a few things deserve a closer look:

• Residency and fellowship years, especially if you trained at more than one institution or moved between states.
• Years when you had two employers, such as a hospital job plus moonlighting, to confirm both sets of wages appear.
• Years with 1099 income from locums work or consulting, where self-employment tax was reported on your return.

Errors are generally easier to sort out while your paystubs and W-2s are still on hand.

Talking It Through

A late start to your career shapes your Social Security benefit, but probably not as much as the years of training might suggest. The wage-base cap and the progressive formula flatten the differences between physician earnings records. Claiming age, and how it interacts with your spouse's benefits and the rest of your retirement income, often matters more.
