What Is the SSR Deduction on My Paycheck?

Many individuals find their pay stubs filled with various abbreviations and codes, one of which is often “SSR.” This deduction represents a fundamental part of how earnings contribute to broader social programs. Understanding what “SSR” signifies on a paycheck helps clarify how a portion of gross wages is allocated before funds reach an employee. This article explains the “SSR” deduction, its components, calculation, and reporting.

Understanding Social Security and Medicare Taxes

The “SSR” deduction on your paycheck refers to Social Security and Medicare taxes, collectively known as Federal Insurance Contributions Act (FICA) taxes. These taxes fund two federal programs. Social Security provides benefits for retirees, individuals with disabilities, and survivors of deceased workers. Medicare is the federal health insurance program for people aged 65 or older, younger people with certain disabilities, and those with End-Stage Renal Disease.

Both employees and their employers share the responsibility for funding these programs. Each party contributes a specific percentage of an employee’s wages. This shared contribution model ensures the stability and availability of these benefits.

How Social Security and Medicare Taxes are Calculated

The calculation of Social Security and Medicare taxes involves specific rates and limits. For 2025, the employee’s Social Security tax rate is 6.2% of their gross wages. This tax applies up to a certain income threshold, known as the Social Security wage base limit. For 2025, this limit is $176,100, meaning any earnings above this amount are not subject to Social Security tax.

The Medicare tax rate for employees is 1.45% of all earned income. There is no wage base limit for Medicare tax, so every dollar an employee earns is subject to this tax. A 0.9% Additional Medicare Tax applies to individual wages exceeding $200,000 in a calendar year. Employers are responsible for withholding this additional tax once an employee’s wages surpass the $200,000 threshold.

Reporting and Withholding

Employers withhold “SSR” deductions directly from an employee’s gross wages. These withheld amounts are then remitted to the U.S. Treasury on behalf of the employee. This process ensures consistent funding for Social Security and Medicare programs throughout the year.

At the end of each year, the total amounts withheld for Social Security and Medicare taxes are reported on an employee’s annual Form W-2, Wage and Tax Statement. Social Security wages and the tax withheld are shown in Box 3 and Box 4, respectively. Medicare wages and the tax withheld are reported in Box 5 and Box 6. This annual statement provides a clear record of an individual’s contributions to these federal programs.
