2026 FICA, Self-Employment Tax & Payroll Withholding: Complete Guide
Last updated: October 26, 2026 · Written by David Chen
What Is FICA Tax?
FICA stands for Federal Insurance Contributions Act. It's the payroll tax that funds Social Security and Medicare — the two biggest social safety net programs in the United States. If you've ever looked at your paystub, you've seen "FICA" or "SOC SEC" listed as a deduction.
Most workers pay FICA tax on every paycheck, starting from your very first dollar earned. There is no standard deduction or personal exemption for FICA — if you earn wages, you pay FICA.
2026 FICA Tax Rates
| Tax Type | Employee Share | Employer Share | 2026 Wage Base Limit |
|---|---|---|---|
| Social Security (Old-Age, Survivors, and Disability Insurance) | 6.2% | 6.2% | $168,600 |
| Medicare (Hospital Insurance) | 1.45% | 1.45% | No cap |
| Additional Medicare Tax (high earners) | 0.9% | 0% | Over $200,000 (single) |
| Total FICA | 7.65% | 7.65% |
The Social Security Wage Base Cap
One important detail: Social Security tax only applies to the first $168,600 you earn in 2026. Once you earn more than that, you stop paying the 6.2% Social Security tax for the rest of the year. That's why high earners see their paychecks go up in January — after they hit the cap, more money shows up in their take-home pay.
Medicare tax has no cap. No matter how much you earn, you always pay 1.45% (plus the extra 0.9% if you make over $200,000).
How FICA Appears on Your Paycheck
If you earn $50,000/year as a W-2 employee, here's how FICA breaks down on your paycheck:
- Gross monthly pay: $4,167
- Social Security (6.2%): $258
- Medicare (1.45%): $60
- Total FICA deduction: $318/month
- Employer matches another $318/month on your behalf
Your employer sends the combined $636/month to the IRS — your $318 plus their $318 match. That's where Social Security and Medicare funding comes from.
Self-Employment Tax (SE Tax)
If you're self-employed (1099, freelance, gig work, small business owner), you pay both the employee AND employer side of FICA. That's called self-employment tax, or SE tax.
2026 Self-Employment Tax Rate
| Component | Rate |
|---|---|
| Social Security | 12.4% (6.2% employee + 6.2% employer) |
| Medicare | 2.9% (1.45% employee + 1.45% employer) |
| Total SE Tax | 15.3% |
The 92.35% Rule
You don't pay SE tax on 100% of your self-employment income. The IRS lets you deduct half of your SE tax before calculating what you owe. That means you only pay 15.3% on 92.35% of your net self-employment earnings, not the full amount.
Example: If you make $100,000 net self-employment income in 2026:
- Step 1: $100,000 × 92.35% = $92,350
- Step 2: Social Security portion: $92,350 × 12.4% = $11,451
- Step 3: Medicare portion: $92,350 × 2.9% = $2,678
- Total SE tax: $14,129
You also get to deduct half of that ($7,065) from your federal income taxes, which softens the blow a bit.
Payroll Withholding Explained
Besides FICA, your employer also withholds federal income tax from your paycheck based on your W-4 elections. The amount withheld depends on:
- Your filing status (single, married filing jointly, etc.)
- How many allowances you claim on your W-4
- Your pay frequency (weekly, biweekly, monthly)
- Any extra withholding you specify

Common Questions
Do I pay FICA on tips?
Yes! Tips are considered wages and are subject to FICA tax. You have to report all tips over $20/month to your employer, and they'll be included on your W-2 at the end of the year.
What if I have two jobs?
If you have two W-2 jobs, both employers will withhold Social Security tax. But you only have to pay Social Security tax up to the $168,600 wage base limit. If you overpay, you'll get that extra money back as a credit when you file your tax return.
Do gig workers (Uber, DoorDash) pay FICA?
Yes! Gig workers are independent contractors, so they pay self-employment tax (15.3%) on their net earnings. You have to pay quarterly estimated taxes if you expect to owe more than $1,000 for the year.
How to Lower Your Self-Employment Tax
The biggest legal way to lower your SE tax is to deduct all your business expenses. Every dollar you deduct lowers your net self-employment income, which lowers your SE tax. Common deductions include:
- Home office deduction
- Mileage (67 cents per mile in 2026)
- Equipment, software, and supplies
- Health insurance premiums
- Retirement contributions (SEP-IRA, Solo 401k)
