How Does an S Corp Affect Social Security Benefits for Solos

Electing S Corp status can lower your tax bill by letting you take part of your business profit as a distribution instead of wages. What’s less talked about: that same distribution doesn’t count toward your Social Security earnings record, which can shrink your future benefit. Here’s how much that actually matters, and how to check the real number for your situation.

The Social Security portion of self-employment tax is 12.4% (Medicare adds another 2.9%, for a combined 15.3% under current law). That 12.4% only applies up to an annual limit called the wage base.

The wage base resets every year and applies per person, to income earned that calendar year. It’s not a lifetime cap and it doesn’t carry over. Earn above it in a given year, and the excess simply isn’t taxed for Social Security or counted toward your benefit for that year.

The wage base also isn’t fixed. It’s adjusted annually for wage growth, and the Social Security Administration typically announces the coming year’s figure each October:

Year	Social Security Wage Base
2024	$168,600
2025	$176,100
2026	$184,500

Check the Social Security Administration’s current wage base before using a figure in your own planning, since it changes most years.

Three things determine your future benefit: work credits, your average lifetime wages, and a formula that converts those wages into a monthly payment.

Work credits. You need 40 credits over your career to qualify for retirement benefits. You can earn up to 4 credits a year, and the amount of wages needed per credit adjusts annually. In 2026, $1,890 in wages earns one credit, so $7,560 earns the maximum four:

Earnings needed to reach 1 through 4 Social Security credits in 2026 Earnings Needed for Social Security Credits (2026) $1,890 1 credit $3,780 2 credits $5,670 3 credits $7,560 4 credits (max)

Most solopreneurs clear the four-credit threshold well before year end, so credits are rarely the part of this equation an S Corp election puts at risk.

Average Indexed Monthly Earnings (AIME). Your 35 highest-earning years, adjusted for wage growth, get averaged into a monthly figure.

Primary Insurance Amount (PIA). Your AIME runs through a formula with two income thresholds called bend points. In 2026, those are $1,286 and $7,749 a month. Earnings up to the first bend point convert to benefits at 90%. Earnings between the two bend points convert at 32%. Earnings above the second bend point convert at only 15%. Bend points adjust annually and depend on the year you become eligible, so treat any specific figure as a current snapshot rather than a fixed rule.

How an S Corp Election Changes Your Earnings Record

Only wages count toward AIME. Distributions don’t. Here’s what that looks like for a business with $100,000 in annual profit, comparing an SMLLC to an SMLLC with S Corp status:

	SMLLC	SMLLC + S Corp Status
Business profit	$100,000	$100,000
Wages counted for Social Security	$100,000	$60,000 (reasonable salary)
Distribution (not counted)	$0	$40,000
Work credits earned this year	4 of 4	4 of 4
Monthly wage figure feeding into AIME	$8,333	$5,000
Bend point tiers this wage reaches (2026 thresholds)	90%, 32%, and 15% tiers	90% and 32% tiers only

The $40,000 difference between the two scenarios mostly falls in the 32% tier, with only a small slice in the lowest-weighted 15% tier. So while the wage gap is large, the resulting gap in monthly Primary Insurance Amount is smaller than the dollar difference suggests, since none of that $40,000 was converting at the full 90% rate to begin with.

The Bottom Line

An S Corp election could reduce your future Social Security benefit, and it’s worth knowing that going in rather than being surprised by it later. In practice, the reduction is often smaller than the dollar amount moved into distributions, because that income tends to fall in the lower-weighted portion of the benefit formula. For most solopreneurs, the payroll tax savings available now are large enough that this tradeoff is a factor to plan around, not a reason to avoid the election.

Setting a defensible reasonable salary and keeping payroll consistent is exactly the kind of ongoing work that’s easy to get wrong without support.
