Have you ever looked at your paycheck and wondered why a portion of your income disappears under something called FICA? Most people see the deduction every month, yet very few stop to ask what it actually means or how the amount is calculated.
That question becomes even more important in 2026 because the updated Social Security wage base changes how much employees contribute and how much employers owe. A small miscalculation or a missed deposit deadline can lead to penalties that pile up quickly, which is why understanding what is FICA is more than just a payroll formality.
This guide breaks down the entire picture in a simple, practical way so employees can read their pay stubs with confidence, employers can stay fully compliant, and self-employed professionals can plan their taxes without surprises. As you read, you will also see how FICA tax connects to benefits, thresholds, reporting rules, and the updates that many businesses are still adjusting to.
2025 FICA Cheat Sheet: Rates and Limits at a Glance
Below is the updated summary for 2025.
2025 FICA Rates Table
| Component | Employee Rate | Employer Rate | 2025 Wage Base Limit |
|---|---|---|---|
| Social Security | 6.2 percent | 6.2 percent | 176,100 dollars |
| Medicare | 1.45 percent | 1.45 percent | No Limit |
| Additional Medicare | 0.9 percent | 0 percent | Thresholds apply |
A simple way to interpret these numbers is to compare them to what are the tax brackets for federal income taxes. While the two systems are separate, employees often evaluate both together to understand how their income will be taxed throughout the year.
For Employees: How FICA Shows Up on the Paycheck
Employees often see multiple abbreviations for the same deduction. This creates confusion, especially for those reviewing their pay stubs closely or planning for year end taxes. Understanding how FICA appears and how it is calculated helps reduce that uncertainty.
Understanding Pay Stub Terms
Pay stubs may list FICA under labels such as OASDI, SS Tax, FICA SS, Medicare, or FICA Med. These are simply different names for Social Security and Medicare contributions. If someone ever asks what is FICA, the easiest answer is that it is the combined deduction that funds retirement, disability, survivors benefits, and Medicare Part A.
How Much Employees Pay in 2025
- Social Security for employees is 6.2 percent of wages up to 176,100 dollars.
- Example: A salary of 50,000 dollars results in a 3,100 dollar FICA Social Security contribution.
- Example: Someone earning 200,000 dollars pays Social Security only on the first 176,100 dollars.
- Medicare is 1.45 percent with no cap.
- Example: A 200,000 dollar salary results in 2,900 dollars in Medicare tax.
- Higher earners may owe an additional 0.9 percent Medicare surtax once wages cross 200,000 dollars. Many employees compare this threshold with what are the tax brackets, since income planning usually considers both.
What FICA Funds
FICA benefits include retirement payments, disability income, survivors benefits, and Medicare Part A. As of mid 2025, the average retirement benefit is about 2,008 dollars per month. Someone retiring at 70 may receive more than 5,100 dollars per month.
Who Is Exempt From FICA
- Students working for their university
- Certain visa holders such as F1 or J1
- Specific religious groups that file Form 4029
Outside of these categories, FICA generally applies to all earned wages.
For Employers: FICA Responsibilities, Deposits, and Compliance
Employers not only withhold FICA from employee wages but also match a large portion of it. Following are the employer responsibilities understand what to plan for throughout the year.
Employer Matching Requirements
Employers match the employee share of FICA, covering 6.2 percent for Social Security and 1.45 percent for Medicare. For example, when a business employs someone earning 100,000 dollars, the employer pays 7,650 dollars in FICA contributions on top of salary.
Understanding Deposit Schedules
- Deposit schedules depend on the IRS lookback period.
- Monthly depositors have 50,000 dollars or less in payroll tax liability.
- Semi weekly depositors have more than 50,000 dollars.
- The next day deposit rule applies when liabilities reach 100,000 dollars in a single day.
Why Late Deposits Become a Trap
Withholding funds correctly is only part of the responsibility. Depositing them on time prevents penalties that can reach 15 percent. Many businesses use bookkeeping outsourcing services to stay ahead of deposit schedules and avoid timing mistakes.
Quarterly Reporting With Form 941
Employers file Form 941 every quarter to report wages and FICA details. The deadlines fall at the end of April, July, October, and January.
New for 2025: Expanded FICA Tip Credit Under OBBB
This update is especially relevant for industries that rely on tipped income. The expansion provides new tax savings opportunities, but only if tracked and reported correctly.
This is one of the most practical changes introduced for 2025.
What Changed Under the New Law
The 45B FICA Tip Credit previously benefited mostly restaurants and beverage service. In 2025, it now includes beauty service businesses such as salons, spas, and barbers. This credit reduces tax liability directly, making it highly valuable for service driven industries.
How Businesses Claim It
To use the credit, employers need accurate tracking of tipped wages and FICA contributions. This is where bookkeeping outsourcing services often support businesses by ensuring tip reporting is consistent, accurate, and audit ready.
High Earners and the Additional Medicare Tax
High earning employees face a separate surtax beyond regular Medicare withholding. This often comes as a surprise, especially when combined with increasing income levels or bonus payouts.
How the Surtax Works
Once an employee’s wages exceed 200,000 dollars, the employer must begin withholding an additional 0.9 percent Medicare tax. This applies even if the employee’s filing status or spouse’s income suggests they may not owe the full surtax. The employer is required to withhold regardless.

Self employed professionals often pay more attention to FICA once they realize they pay both the employee and employer portions. This section explains the mechanics in a way that helps freelancers, consultants, and small business owners plan ahead.
These rules matter especially for tax and entity planning.

Self employed taxpayers pay 12.4 percent for Social Security and 2.9 percent for Medicare. Half of this amount is deductible when filing an income tax return. Some owners consider S Corporation structures to adjust how FICA applies to their income.
