Your Paycheck
Social Security Cap Tracker
Social Security (6.2%) stops being withheld once your wages reach the annual SS wage base — $184,500 in 2026. After that paycheck, your take-home increases by exactly that 6.2% for every remaining check of the year. Enter your salary to see exactly which paycheck crosses the cap.
Informational only — not financial advice. Covers Social Security withholding only; Medicare (1.45%) continues all year with no wage cap.

How this calculator works
The SS wage base
Social Security is withheld at 6.2% of wages up to an annual ceiling called the contribution and benefit base — commonly called the SS wage base. For 2026 it is $184,500, announced by the SSA each October (SSA.gov). Once your cumulative SS-taxable wages for the year reach that ceiling, SS withholding stops for the remainder of the year.
Finding the crossover paycheck
The calculator computes SS-taxable wages per paycheck (gross minus any Section 125 pre-tax benefits), then finds the paycheck where the cumulative total crosses the wage base:
- Full periods: floor(SS wage base ÷ SS wages per check). Each of these paychecks has full SS withheld.
- Crossover paycheck: if there is a remainder after the full periods, the next paycheck has partial SS withheld (only on the remaining taxable wages up to the cap).
- After the cap: $0 SS withheld — take-home increases by the full 6.2% per paycheck for every remaining check of the year.
Section 125 and FICA-taxable wages
Pre-tax benefits under a Section 125 cafeteria plan (health, dental, vision, FSA, HSA) reduce the wages subject to FICA per IRC § 3121(a)(5). Because fewer wages are SS-taxable each paycheck, it takes more paychecks to reach the annual cap — moving the crossover date later. 401(k) pre-tax contributions do not reduce FICA-taxable wages (IRC § 3121(a)), so they are not included in this calculation.
What this calculator doesn’t cover
Medicare (1.45%) has no wage cap and is not tracked here — it continues on all wages for the full year. The Additional Medicare Tax (0.9%) applies above $200,000 in wages and is also separate.
Mid-year starts and pay changes are not modeled. The calculator assumes a full calendar year at the entered salary. If you started or changed pay mid-year, adjust your annual figure to reflect actual expected wages.

Frequently asked questions
What is the Social Security wage base?
The SS wage base is the annual earnings ceiling above which Social Security tax is no longer withheld. For 2026, that cap is $184,500. The SSA announces a new figure each October, adjusted most years to track the national average wage index.
What happens to my paycheck once I hit the SS cap?
Your gross pay is unchanged, but Social Security (6.2%) is no longer withheld — so your net take-home increases by exactly that 6.2% of your SS-taxable wages per paycheck. Medicare (1.45%) continues all year with no wage cap.
Does the Social Security cap affect both the employee and employer?
Yes. Both the employee (6.2%) and employer (6.2%) stop paying Social Security on wages above the wage base. After the cap, neither side owes SS on additional earnings — only Medicare continues for both.
Why do pre-tax health benefits move the cap date later?
Section 125 pre-tax benefits — health, dental, vision, FSA, HSA — reduce your FICA-taxable wages per paycheck. Lower SS-taxable wages per check means it takes more paychecks to accumulate enough taxable wages to hit the annual cap, pushing the crossover date later in the year.
