Social Security & Medicareintermediate3 answers · 6 min readUpdated February 28, 2026

Quick Answer

Most government employees hired after 1983 pay Social Security taxes at the standard 6.2% rate on wages up to $176,100 (2026). However, some federal employees in CSRS and certain state/local workers may be exempt from Social Security taxes but still pay Medicare taxes at 1.45%.

How Social Security tax works for FERS employees


If you're a federal employee hired after December 31, 1983, you're automatically enrolled in the Federal Employees Retirement System (FERS) and pay full Social Security taxes just like private sector employees. You'll see 6.2% deducted from your paycheck for Social Security on wages up to $176,100 in 2026, plus 1.45% for Medicare on all wages.


Example: FERS employee earning $95,000


Let's break down the payroll taxes for a GS-13 federal employee earning $95,000 annually:


  • Social Security tax: $95,000 × 6.2% = $5,890 per year ($226.54 per biweekly paycheck)
  • Medicare tax: $95,000 × 1.45% = $1,378 per year ($53 per biweekly paycheck)
  • Total FICA taxes: $7,268 per year ($279.54 per paycheck)

  • This is identical to what a private sector employee earning $95,000 would pay.


    FERS vs. CSRS: The key difference


    The major distinction is your hire date:



    What this means for your retirement


    As a FERS employee paying Social Security taxes, you're earning credits toward Social Security benefits. You need 40 quarters (10 years) of covered employment to qualify. In 2026, you earn one credit for each $1,810 in wages, up to 4 credits per year.


    Your retirement will come from three sources:

    1. FERS pension: Based on years of service and high-3 average salary

    2. Social Security: Based on your 35 highest-earning years

    3. Thrift Savings Plan (TSP): Your 401(k)-style account with government matching


    Special situations for government employees


    High earners: If you earn over $176,100 in 2026, you'll stop paying Social Security tax on wages above this amount, but you'll continue paying Medicare tax on all income. If you earn over $200,000 (single) or $250,000 (married filing jointly), you'll pay an additional 0.9% Medicare tax.


    Multiple jobs: If you have a federal job plus outside employment, both employers will withhold Social Security tax up to the annual limit. If your combined wages exceed $176,100, you may get a refund when filing taxes.


    State and local employees: Rules vary significantly. Some participate in Social Security, others don't. Check with your HR department about your specific pension system.


    What you should do


    Review your pay stub to confirm Social Security and Medicare taxes are being withheld if you're in FERS. If you're unsure about your retirement system or see unexpected withholding, contact your HR office immediately. Use our paycheck calculator to verify your deductions are correct and understand your true take-home pay.


    Key takeaway: FERS employees pay the same Social Security taxes as private sector workers (6.2% up to $176,100) and earn full Social Security benefits, while most CSRS employees are exempt from Social Security taxes but receive higher pension benefits.

    Key Takeaway: FERS employees pay standard Social Security taxes (6.2% up to $176,100) and earn full Social Security benefits, creating a three-legged retirement stool with pension, Social Security, and TSP.

    Best for federal employees hired before 1984 who participate in the Civil Service Retirement System

    CSRS employees and Social Security exemption


    If you were hired as a federal employee before 1984 and remained in the Civil Service Retirement System (CSRS), you generally don't pay Social Security taxes on your federal wages. However, you still pay Medicare tax at 1.45% on all earnings.


    Example: CSRS employee earning $85,000


  • Social Security tax: $0 (exempt)
  • Medicare tax: $85,000 × 1.45% = $1,233 per year ($47.42 per biweekly paycheck)
  • CSRS retirement deduction: $85,000 × 7% = $5,950 per year ($228.85 per paycheck)

  • Your total federal retirement-related deductions are $7,183 annually—less than what FERS employees pay in FICA taxes alone.


    The trade-off: Higher pension, limited Social Security


    CSRS provides a more generous pension formula (typically 2% per year of service vs. 1% for FERS), but you won't earn Social Security credits from your federal employment. If you worked in Social Security-covered employment before or after federal service, those earnings may qualify you for Social Security benefits, but they could be reduced by the Windfall Elimination Provision (WEP).


    What you should do


    Track any non-federal employment where you paid Social Security taxes. Even part-time or seasonal work counts toward your 40 quarters needed for Social Security eligibility. Consider whether the higher CSRS pension outweighs the loss of Social Security benefits in your retirement planning.


    Key takeaway: CSRS employees save money on payroll taxes (no 6.2% Social Security tax) but may face reduced Social Security benefits if they qualify through other employment.

    Key Takeaway: CSRS employees don't pay Social Security tax on federal wages, saving 6.2% in payroll deductions but potentially losing Social Security benefits that could be worth $20,000+ annually in retirement.

    Best for state, county, city, and local government employees with varying Social Security participation

    State and local government Social Security participation


    Unlike federal employees, state and local government workers have widely varying Social Security participation. Some states opted their employees into Social Security, others didn't, and some allow individual choice.


    Examples by state type


    Full participation states (like California, New York): All state and local employees pay Social Security taxes and earn full benefits, just like private sector workers.


    Non-participating states (like Ohio teacher pensions, some Texas municipal plans): Employees don't pay Social Security taxes on government wages but may be subject to WEP/GPO if they have other Social Security-covered employment.


    Mixed participation: Some employee groups participate, others don't, often based on hire date or employee choice.


    What this means for your paycheck


    If your state/local government participates in Social Security:

  • You pay 6.2% Social Security tax + 1.45% Medicare tax
  • You earn Social Security credits
  • Your government pension won't trigger WEP/GPO reductions

  • If your government doesn't participate:

  • You pay only 1.45% Medicare tax (no Social Security tax)
  • You don't earn Social Security credits from government work
  • Any Social Security benefits from other jobs may be reduced by WEP/GPO

  • What you should do


    Check your pay stub and contact HR to confirm your Social Security participation status. If you're not participating, track any private sector employment carefully—those earnings become crucial for Social Security eligibility and benefit calculations.


    Key takeaway: State and local government Social Security participation varies dramatically by location and employee group—check your specific situation to understand your retirement planning needs.

    Key Takeaway: State and local government Social Security participation varies by jurisdiction—some pay full FICA taxes and earn full benefits, others pay only Medicare tax and face potential WEP/GPO benefit reductions.
