Quick Answer
For 2026 the Social Security wage base is $184,500, up from $176,100. Workers at or above it pay $520.80 more, for a maximum of $11,439.00; anyone under $176,100 pays nothing extra.
The Social Security wage base — the ceiling above which the 6.2% tax stops — rose from $176,100 in 2025 to $184,500 in 2026. Anyone earning above the old ceiling pays more this year on exactly the same salary.
The maximum any employee can pay in 2026 is $11,439.00, which is 6.2% of the wage base. Your employer pays the same again, invisibly.

The one place your marginal rate falls
Crossing $184,500 has a visible effect on a paycheck: Social Security stops for the rest of the year, so take-home jumps mid-year without anything else changing.
To see it cleanly you have to compare two salaries inside the same federal bracket, otherwise a bracket step hides the effect. In Texas, a single filer on $180,000 faces a marginal rate of 31.7% on the next dollar. At $195,000 — same 24% federal bracket, still below the Additional Medicare threshold — it is 25.4%. The whole 6.2% difference is Social Security switching off.
It does not stay that low. Keep going and the effect reverses: by $250,000 the marginal rate is back up to 34.4%, because the federal bracket has stepped to 32% and the 0.9% Additional Medicare surtax has started above $200,000. Passing the wage base is a dip, not a permanent discount.
The Additional Medicare thresholds have never been indexed for inflation since they were introduced. The wage base rises every year; that threshold does not. Each year it therefore catches more people.
For 2027: SSA has set the base at $192,300. What that changes, salary by salary, is in the 2027 wage base article.
