Social Security Planning for Dentists: When to File and How Much to Expect

Most dentists assume Social Security is an afterthought — a small check compared to practice income and retirement savings. That assumption is expensive. A dentist who earns at or above the Social Security wage base for 35+ years and claims at age 70 instead of 62 collects up to $5,181/month vs. $2,969/month in 2026 dollars — a $26,544 annual difference, tax-adjusted, for life. Over a 20-year retirement, that timing decision alone is worth $350,000–$500,000 in lifetime income.

The decision is more complex than the brochure version. Dentists face tax exposure on SS benefits that salaried employees often avoid, because practice sale proceeds and required minimum distributions tend to push provisional income well above the taxation thresholds. Getting the timing right — relative to your practice sale, Roth conversion strategy, and spouse's benefit — can materially reduce the tax hit on top of the timing gain.

1. How dentists build Social Security credits

Every dentist with self-employment income — whether operating as a sole proprietor, PLLC, or PC — pays self-employment (SE) tax of 15.3% on net earnings: 12.4% goes to Social Security (OASDI) and 2.9% to Medicare. The Social Security portion only applies up to the annual wage base ($184,500 in 2026). Income above that still gets Medicare tax, but doesn't increase your SS record.

S-corporation dentists pay SS tax only on their W-2 salary, not on distributions — which is one of the main S-corp tax advantages. But it also means that if your W-2 salary is set too low, you may be building a weaker SS record than you realize. The IRS requires "reasonable compensation," and most dental S-corps pay $120,000–$180,000 in W-2 wages, which is enough to build a near-maximum SS record for most of a career.

You earn Social Security credits by working. In 2026, you earn one credit for every $1,810 in covered earnings, up to four credits per year.¹ You need 40 credits (10 years of work) to qualify for retirement benefits. Most dentists earn their 40 credits long before retirement; after that, additional credits don't unlock more eligibility — only the level of your lifetime earnings record matters.

SS calculates your benefit from your highest 35 years of inflation-adjusted earnings. For dentists who earned at or above the wage base for most of their career, the benefit calculation is effectively maxed out. Extending your career by a few more years generally won't move the needle much — but when you claim moves it dramatically.

2. The claiming age decision: 62 vs. 67 vs. 70

Your Full Retirement Age (FRA) is the benchmark. For anyone born in 1960 or later, FRA is 67. You can claim as early as 62 or delay as late as 70, and each choice locks in a permanent benefit level.

Source: SSA, 2026 figures. Max benefit applies to workers with maximum taxable earnings throughout career. Most dentists will be near (not exactly at) the maximum.

Break-even analysis

If you claim at 62 instead of 70, you collect $2,969/month for 8 years while your age-70 counterpart collects nothing — that's $284,990 in payments received before age 70. But after age 70, the delayed claimer receives $2,212/month more ($5,181 vs. $2,969). Divide $284,990 by $2,212: you break even at roughly 129 months past age 70 — around age 80 to 81.

If you live past 81, delaying to 70 produces more lifetime income. The SSA's own actuarial tables show average life expectancy at age 62 in reasonably good health is approximately 84–87. Most dentists who are still in clinical practice at 62 are in above-average health — putting the average break-even well within life expectancy. The actuarial bet almost always favors delay.

Important caveat: this is a pre-tax calculation. Once you layer in the SS taxation rules (Section 3 below), the case for delay gets even stronger for high-income dentists, because taxable income management around the timing of your claim can reduce the effective tax rate on your benefits.

3. The Social Security taxation trap

Up to 85% of Social Security benefits are taxable as ordinary income — but only if your "provisional income" (adjusted gross income + tax-exempt interest + half of SS benefits) exceeds certain thresholds. These thresholds have not been inflation-adjusted since 1983–1993:²

For single filers the thresholds are $25,000 and $34,000. Given how low these thresholds are, nearly every dentist with any investment income, RMDs, or part-time practice income in retirement will have 85% of their SS benefit taxed as ordinary income. At a 22% marginal bracket, your effective SS benefit is reduced by roughly 18.7% (85% × 22%).

This makes the pre-claim period a critical planning window. In the years before you claim SS — if you've already sold or wound down the practice — your income can drop substantially. That gap is the ideal time for Roth conversions: you're filling lower brackets, reducing your future pre-tax account balances (and thus future RMDs), and shrinking the provisional income base that will trigger SS taxation later. A Roth conversion strategy that depletes $500,000–$1M in pre-tax accounts before you claim SS can save $30,000–$80,000 in lifetime taxes on Social Security alone.

4. WEP and GPO: good news for VA, military, and academic dentists

Before 2025, dentists who split their careers between private practice (paying Social Security) and government employment (covered by a separate pension — VA, military, federal, or some state university positions) were penalized by two rules:

• Windfall Elimination Provision (WEP): Reduced SS benefits for workers who also receive a non-covered government pension.
• Government Pension Offset (GPO): Reduced spousal/survivor SS benefits when the non-covered spouse receives a government pension.

The Social Security Fairness Act, signed in January 2025, repealed both WEP and GPO entirely.³ Dentists who worked for the VA, military, or a state university dental school — and who receive or will receive a government pension — now get their full Social Security benefit, unreduced. If you were already claiming and had benefits reduced by WEP, SSA has been processing retroactive payments and benefit increases.

If you're a VA dentist, military dentist, or dental school faculty who worked under a non-covered government pension, revisit your SS estimate on SSA.gov — it may be meaningfully higher than a pre-2025 projection showed.

5. Spousal benefit strategies

If you're married, your claiming strategy affects both spouses. Key mechanics:

• Spousal benefit: A spouse who worked little or earns a much lower SS benefit can claim up to 50% of your FRA benefit (not your age-70 delayed benefit). The spousal benefit tops out at 50% of your FRA amount regardless of when you claim. This means your delayed credits (the extra 8%/year from 67 to 70) accrue only to you, not to the spousal benefit calculation.
• Survivor benefit: When one spouse dies, the survivor receives the higher of their own benefit or the deceased spouse's benefit. This is where your delayed credits fully transfer. If you have the higher lifetime earnings and you claim at 70, your $5,181/month becomes the survivor's benefit after your death — for life. For a younger spouse, this is often worth far more than the spousal benefit math suggests.
• Sequencing: A common strategy for two-income couples: the lower-earning spouse claims at 62 (to bring in income while assets are still appreciating), while the higher-earning spouse delays to 70 to maximize both the personal benefit and the survivor benefit.

For a dentist who is the primary earner with a spouse who worked part-time or not at all, the survivor benefit often drives the delay decision more than the break-even analysis does. A 70-year-old dentist leaving a $5,181/month survivor benefit to a 67-year-old spouse who might live to 92 is potentially providing $1.5M in present value — an insurance function that no other planning tool replicates.

6. Working while collecting: the earnings test

If you claim SS before your Full Retirement Age and continue working (in your practice or part-time elsewhere), SSA applies an earnings test that temporarily reduces your benefit:

Source: SSA, 2026 earnings test exempt amounts. Withheld benefits are not lost — SSA recalculates your benefit upward at FRA to credit the months you weren't paid.

For most active dentists earning $200,000–$500,000+ in clinical income, claiming SS before FRA makes almost no sense — you'd lose nearly the entire benefit to the earnings test. The earnings test is another reason why delaying to 70 is the right call for dentists still in practice through their mid-60s.

After FRA (month you turn 67 and beyond), you can earn any amount with zero benefit reduction — there is no earnings limit. A dentist who scales back to one day per week at age 67 can claim SS without penalty on the days-worked income.

7. Coordinating SS with your practice sale

The year you sell your practice is typically a high-income year even with careful tax planning — goodwill proceeds, installment income, possible earnout payments, and any equipment recapture. Adding SS benefits on top of that income in the sale year would push 85% of SS into a high marginal bracket (possibly 32–37%).

Practical sequencing for a dentist planning to sell between ages 62 and 70:

1. Sell the practice. Complete the asset sale, installment election, or DSO deal. This year's income will be high — don't add SS to it.
2. Use the post-sale income gap for Roth conversions. If installment payments are spread over 5–7 years, you'll have years with lower income — fill those brackets with conversions from your solo 401(k), SEP-IRA, or cash balance plan rollover.
3. Claim SS at 70. By then, RMDs haven't fully kicked in yet (RMD age is 73 for anyone born 1951–1959; 75 for born 1960+, per SECURE 2.0). Your first few years of SS may have a lower provisional income than later years when RMDs compound.

The optimal sequence — practice sale → Roth conversion window → SS at 70 — requires modeling several years of projected income, Roth conversion amounts, and bracket thresholds simultaneously. This is one of the highest-value planning exercises a fee-only advisor does for dentists approaching retirement.

8. What your SS benefit actually looks like

You can see your own estimated benefit at my Social Security (SSA.gov). The projection tool shows estimates at 62, FRA, and 70 based on your actual earnings record. It also flags if you haven't yet paid in 35 years of covered earnings (which would lower your benefit — each zero year in the 35-year average pulls the average down).

The SSA estimate assumes you'll continue earning at your current level until claiming. For a dentist planning to sell the practice at 63 and stop working, the SSA projection will overstate the benefit slightly — but for dentists with 30+ years of maximum-wage-base earnings, the effect is marginal. A few zero-earnings years in a 35-year average with 30 years at the maximum barely move the calculation.

9. The financial advisor's role in SS planning

Social Security strategy doesn't exist in isolation — it interacts with Roth conversions, RMD planning, estate planning, Medicare IRMAA brackets, and practice sale timing. A fee-only financial advisor who works with dental practice owners will model:

• Your break-even age given your health history, family longevity, and financial resources
• Year-by-year provisional income projections from now through your 80s, including RMD growth
• The optimal Roth conversion amount each year to minimize lifetime SS taxation
• The interaction with Medicare IRMAA — Roth conversions in the wrong year can trigger $1,000+/month in Medicare premium surcharges (see our Roth conversion guide for IRMAA thresholds)
• Spousal benefit coordination, including the survivor benefit value of delay
• How your practice sale structure (installment note vs. lump sum vs. DSO earnout) changes the timing math
