Reduces federal income tax but NOT FICA. 2026 limit: $24,500
Section 125 deductions reduce BOTH federal tax AND FICA
2026 FICA breakdown
FICA is the payroll tax that funds Social Security and Medicare. For 2026, the rates and limits are:
| Tax | Rate | Wage base | Max tax |
|---|---|---|---|
| Social Security (employee) | 6.2% | $184,500 | $11,439 |
| Medicare (employee) | 1.45% | No cap | No max |
| Additional Medicare | 0.9% | Over $200K single / $250K MFJ | No max |
| Employer SS + Medicare | 7.65% | Same caps | Match |
| Total combined FICA | 15.3% | Same caps | $22,878 |
The combined 15.3% is what self-employed people pay (they are both the employee and the employer). Self-employed people get to deduct half of the SE tax as a business expense, which roughly equals the employer match.
The 401(k) trick that does NOT save FICA
One of the most common payroll tax misconceptions: contributing to a 401(k) reduces both federal income tax and FICA. It does not reduce FICA.401(k), 403(b), and 457 contributions reduce your federal taxable income, which lowers your federal income tax bill, but they do NOT reduce your FICA wages. You still pay 7.65% FICA on every dollar of your salary, including the portion that goes to your 401(k).
What actually reduces both federal tax and FICA:Section 125 cafeteria plan deductions. These include employer-sponsored health insurance premiums, dental, vision, FSA, dependent care FSA, and HSA contributions made through payroll. Every dollar you put into one of these accounts saves you 7.65% in FICA on top of your marginal federal income tax savings.
This is why HSAs are called triple tax-advantaged.Contributions made through payroll deduction are tax-free (federal + FICA), the money grows tax-free, and qualified medical withdrawals are tax-free. No other account in the US tax code has this combination.
Three real take-home pay scenarios
1. The $60,000 single earner
Sarah earns $60,000 gross with no pre-tax deductions, files single. Federal tax on $43,900 taxable: $5,020. FICA: 7.65% × $60,000 = $4,590. Total taxes: $9,610. Take-home: $50,390/year, or about $4,200/month, $1,940/biweekly, $970/week. Effective combined tax rate: 16.0% of gross.
2. The $120,000 earner with $10K in 401(k)
Marcus earns $120,000 gross, contributes $10,000 to his 401(k), files single. Federal taxable income: $93,900 ($120K - $10K - $16,100). Federal tax: about $14,200. FICA on full $120,000 (because 401(k) does NOT reduce FICA): $9,180. Total taxes: $23,380. Take-home after taxes and 401(k): $86,620/year, or about $7,220/month. Effective combined tax rate: 19.5% of gross.
3. The $250,000 high earner
Lisa earns $250,000 gross single, no pre-tax deductions. Federal tax on $233,900 taxable: about $52,900. Social Security capped at $184,500: $11,439. Medicare on full $250,000: $3,625. Additional Medicare on $50,000 over $200K: $450. Total taxes: about $68,400. Take-home: $181,600/year, or about $15,130/month. Notice she hits the SS wage base mid-year, getting a small "raise" in her paychecks for the last few months of the year as SS withholding stops.
Common take-home pay mistakes
1. Assuming your 401(k) contribution saves FICA
It does not. 401(k) only reduces federal income tax, not the 7.65% FICA. Section 125 deductions like health insurance are the ones that save both.
2. Forgetting state income tax
Depending on where you live, state income tax adds anywhere from 0% (Texas, Florida) to 13.3% (California top rate). This calculator shows federal only.
3. Confusing your withholding with your actual tax
What your employer withholds is just an estimate based on your W-4. Your actual tax is calculated when you file. Refunds and balances due are the difference.
4. Negotiating salary in net terms
Always negotiate gross. Net depends on too many variables (filing status, deductions, state) that the employer cannot know. Gross is the universally comparable number.
5. Targeting a large refund as a "savings strategy"
The average tax refund is over $3,000 — meaning the average taxpayer overwithholds by $250+/month and gives the IRS an interest-free loan. Adjust your W-4 to break even and put that money to work.
Frequently asked questions
How is my take-home pay calculated?
Take-home pay (also called net pay) starts with your gross salary, then subtracts: (1) pre-tax deductions like 401(k), health insurance, HSA, and FSA contributions, (2) federal income tax based on your taxable income and filing status, (3) FICA taxes including Social Security (6.2% on the first $184,500 in 2026) and Medicare (1.45% on all wages), and (4) any state and local income taxes if applicable. This calculator covers federal income tax and FICA. State taxes are not included since they vary widely.
What is FICA and how much is it in 2026?
FICA (Federal Insurance Contributions Act) is the payroll tax that funds Social Security and Medicare. For 2026, employees pay 6.2% Social Security on the first $184,500 of wages (the wage base), capping at $11,439, plus 1.45% Medicare on all wages with no cap. Total employee FICA is 7.65% on most wages. Employers match this for an additional 7.65%, bringing the combined burden to 15.3% — which is what self-employed people pay themselves. High earners pay an additional 0.9% Medicare on wages over $200,000 (single) or $250,000 (married joint).
What is the 2026 Social Security wage base?
The 2026 Social Security wage base is $184,500, up from $176,100 in 2025. This means only the first $184,500 of your wages are subject to the 6.2% Social Security tax. Wages above this amount are still subject to Medicare tax (1.45%) and the Additional Medicare tax (0.9% over $200K), but no more Social Security tax. For high earners, this creates a small "raise" in take-home pay later in the year once you cross the wage base. Maximum 2026 employee Social Security tax is $11,439.
Does my 401(k) contribution lower my FICA?
No. 401(k) contributions reduce your federal income tax (because they reduce your taxable income), but they do NOT reduce your FICA wages. You still pay the full 7.65% Social Security and Medicare on your gross salary including the 401(k) contribution. This is different from health insurance and HSA contributions through a Section 125 cafeteria plan, which DO reduce both federal income tax and FICA. The result: contributing to a 401(k) saves you 22-32% in income tax but $0 in FICA.
What pre-tax deductions reduce both income tax and FICA?
Section 125 cafeteria plan deductions reduce both federal income tax AND FICA wages: employer-sponsored health insurance premiums, dental, vision, FSA (flexible spending account), HSA contributions made through payroll, and dependent care FSA. By contrast, 401(k), 403(b), and 457 contributions only reduce federal income tax — they do not reduce FICA. This is why an HSA is sometimes called a "triple tax-advantaged" account: tax-free contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses, plus FICA savings on contributions.
How much does my employer pay in payroll taxes?
For every dollar you pay in FICA, your employer matches it. Your 7.65% becomes 15.3% combined. Employers also pay federal unemployment tax (FUTA) of 6% on the first $7,000 of wages (typically reduced to 0.6% with the state credit), plus state unemployment insurance which varies by state and the employer's claim history. So while you see 7.65% on your pay stub, your employer is paying roughly 8-10% on top for the right to employ you. This is why a $100,000 salary actually costs your employer about $108,000-$110,000.
What is the Additional Medicare Tax?
The Additional Medicare Tax is an extra 0.9% Medicare tax on wages above certain thresholds: $200,000 for single filers, $250,000 for married filing jointly, $125,000 for married filing separately. The thresholds are not indexed to inflation, so they have been the same since 2013. Only employees pay this tax — there is no employer match. Employers must begin withholding it once an employee's YTD wages exceed $200,000, regardless of filing status. You may owe more or less than what was withheld when you file your return.
How much state income tax will I pay?
It depends on where you live. Nine states have no state income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Other states range from flat rates around 3-5% (Pennsylvania, Indiana, Michigan, North Carolina) to graduated brackets reaching 13.3% top rate (California). Most states use brackets similar to federal but with different thresholds. This calculator does not include state tax — add an estimate based on your state's rates to get full take-home pay.
What is the difference between gross pay and net pay?
Gross pay is your salary before any deductions — what you negotiated when you took the job. Net pay (take-home pay) is what actually hits your bank account after federal income tax, FICA, state income tax, retirement contributions, health insurance, and any other payroll deductions are removed. The gap can be substantial: a $100,000 single filer in California might have a gross of $100,000 but a net of around $66,000-$68,000 — about a 33% reduction. Always negotiate gross, not net.
Why is my paycheck different from what this calculator shows?
A few common reasons: (1) you have state income tax that this calculator does not include, (2) your employer is withholding based on your W-4 elections, which may differ from actual tax owed, (3) you have additional pre-tax or post-tax deductions like garnishments, life insurance, or commuter benefits, (4) you receive supplemental wages like bonuses that are withheld at a flat 22% (37% over $1 million), or (5) you live in a state or locality with additional payroll taxes (NY SDI, CA SDI, etc.).
What is the W-4 form and how does it affect my take-home pay?
Form W-4 tells your employer how much federal income tax to withhold from each paycheck. The current version (revised in 2020) asks about other jobs, dependents, additional income, and adjustments. Claiming more allowances/dependents reduces withholding (more take-home now, potentially smaller refund or owe at tax time). Claiming fewer increases withholding (less take-home now, potentially larger refund). The goal is to match what you actually owe — neither overwithhold (giving the IRS an interest-free loan) nor underwithhold (potentially facing underpayment penalties).
Should I aim for a tax refund or break-even at tax time?
Mathematically, breaking even is best because it means you held your own money throughout the year instead of giving an interest-free loan to the IRS. The average refund is over $3,000, which means most Americans are overwithholding by $250+ per month. Adjusting your W-4 to break even would put that money in your paycheck immediately, where it could pay down debt, build emergency savings, or earn interest. That said, many people use refunds as a forced savings mechanism — if that is the only way you save, the math becomes more nuanced.
