What Actually Gets Taken Out of My Paycheck? Every Deduction Explained

You earn $5,000 every two weeks — but only $3,800 shows up in your bank account. Where did the other $1,200 go?

The answer: a layered stack of mandatory taxes, statutory payroll contributions, and voluntary deductions that your employer withholds before your net pay is calculated. Some are required by federal law. Some are required by your state. And some are deductions you elected — even if you don’t remember choosing them.

This guide is a complete, itemized reference to every single thing that gets taken out of a paycheck in 2026 — organized by category, with the exact rates, caps, and thresholds you need to know.

Key Takeaways

• Your paycheck passes through three mandatory tax layers (federal income tax, Social Security, Medicare) and potentially a fourth (state/local tax) before reaching your bank account.
• FICA taxes alone take 7.65% of every dollar you earn (up to the Social Security wage cap). This is non-negotiable and cannot be reduced by filing status or deductions.
• Federal income tax withholding is an estimate based on your W-4 — it’s not your final tax bill. You can adjust it at any time.
• Voluntary deductions — 401(k), health insurance, HSA, FSA — come out of your paycheck, but many of them reduce your taxes and effectively pay you back.
• Most American workers take home 70%–85% of their gross pay, depending on income level, state of residence, and benefit elections.

The Two Categories: Mandatory vs. Voluntary

Everything taken from your paycheck falls into one of two buckets:

Mandatory deductions are calculated by your employer’s payroll system based on your W-4, your earnings, and the tax laws of your state. You can influence the amount of federal withholding by adjusting your W-4, but you cannot opt out of taxes entirely.

Voluntary deductions are benefits you elected during enrollment — and many of them are pre-tax, meaning they reduce your taxable income and save you money on taxes.

Let’s walk through every item.

1. Federal Income Tax Withholding (FIT / FWT)

What it is: The largest variable deduction on most paychecks. Your employer estimates how much federal income tax you’ll owe for the year and withholds a portion from each paycheck, remitting it directly to the IRS on your behalf.

How it’s calculated: Based on three inputs from your IRS Form W-4:

1. Your filing status (single, married filing jointly, head of household)
2. Any additional income or deductions (Step 2 and Step 4 of the W-4)
3. Tax credits (Step 3 — e.g., child tax credits)

Your employer uses IRS Publication 15-T to calculate the per-period withholding amount by annualizing your paycheck, applying the 2026 progressive tax brackets, and dividing back down to your pay frequency.

2026 Federal Tax Brackets (Single Filer):

Key detail: Federal income tax withholding is an estimate — not your final tax bill. When you file your 1040 in April, the IRS calculates your actual liability and either refunds the overage or bills you for the shortfall. If you consistently get large refunds, you’re overwithholding — use the IRS Withholding Estimator to adjust your W-4 and get more in each paycheck.

How to reduce it (legally):

• Increase pre-tax 401(k) or HSA contributions (lowers taxable income)
• Update your W-4 to claim eligible credits (child tax credit, dependent care)
• Claim the 2026 overtime deduction if you work overtime hours

2. Social Security Tax (OASDI)

What it is: A mandatory payroll tax that funds the Social Security retirement and disability insurance program. On your pay stub, it may appear as “OASDI,” “SS,” “Soc Sec,” or simply “Social Security.”

The rate: 6.2% of your gross wages — flat, no brackets. Your employer pays an additional matching 6.2%, for a combined 12.4%.

The cap: Social Security tax only applies to the first $176,100 of your earnings in 2026 (the “contribution and benefit base”). Once your year-to-date earnings pass this threshold, Social Security stops being withheld for the rest of the calendar year. You’ll notice your paychecks get slightly larger in late fall or winter if your salary exceeds this cap.

Example: On a $100,000 salary, you pay $100,000 × 6.2% = $6,200 in Social Security tax for the year.

Can you reduce it? No — Social Security tax is calculated on gross wages before most deductions. However, employer-sponsored health insurance premiums under a Section 125 cafeteria plan are exempt from FICA, which does reduce your Social Security tax slightly.

3. Medicare Tax (HI)

What it is: A mandatory payroll tax that funds the federal Medicare hospital insurance program. It appears on your stub as “Medicare,” “Med,” or “HI.”

The rate: 1.45% of all gross wages — no cap, no ceiling. Unlike Social Security, Medicare tax never stops.

Additional Medicare Tax: If your wages exceed $200,000 (single) or $250,000 (married filing jointly) in a calendar year, an extra 0.9% surtax kicks in under the Affordable Care Act. Your employer does not match this additional 0.9%.

Example: On a $100,000 salary, you pay $100,000 × 1.45% = $1,450 in Medicare tax. On a $250,000 salary (single), you pay ($200,000 × 1.45%) + ($50,000 × 2.35%) = $2,900 + $1,175 = $4,075.

4. FICA: The Combined Payroll Tax

FICA stands for the Federal Insurance Contributions Act. It’s not a separate tax — it’s the combined total of Social Security (6.2%) and Medicare (1.45%):

This 7.65% comes out of every single paycheck with very few exceptions. It is the most predictable deduction on your stub because it has no brackets and no filing-status variations (until the Additional Medicare Tax threshold).

Annual FICA on common salaries:

*Social Security caps at $176,100 × 6.2% = $10,918.20. No Social Security is withheld on earnings above $176,100.

5. State Income Tax

What it is: If you live or work in a state that levies income tax, your employer withholds an estimated amount from each paycheck — similar to federal withholding, but based on your state’s brackets and rules.

Who pays it: Workers in 41 states plus D.C. pay state income tax. Nine states have zero state income tax: Alaska, Florida, Nevada, New Hampshire (wages only), South Dakota, Tennessee, Texas, Washington, and Wyoming.

How much: Rates vary wildly — from a flat 2.5% in Arizona to a top marginal rate of 13.3% in California. Some states use flat rates (Illinois: 4.95%, Indiana: 3.05%), while others have progressive brackets similar to the federal system.

How to find yours: Use our 50-State Paycheck Calculator to see your exact state withholding for any salary. You can also compare the Texas, Florida, or Nevada zero-tax calculators to see the difference.

6. Local and City Income Taxes

What it is: Some cities and municipalities levy their own income tax on top of federal and state taxes. This is less common, but it affects millions of workers.

Notable examples:

• New York City: 3.078% – 3.876% on residents
• Philadelphia, PA: 3.75% city wage tax (residents), 3.44% (non-residents)
• Detroit, MI: 2.4% on residents
• Ohio cities: Many Ohio municipalities levy 1%–3% local income taxes

Most states do not have local wage taxes. If your pay stub shows a line labeled “City Tax,” “Local Tax,” or “Municipal Tax,” you’re in one of the areas that does.

7. 401(k) / 403(b) / 457(b) Retirement Contributions

What it is: Money you’ve elected to contribute to your employer-sponsored retirement plan. These deductions appear as “401k,” “Retirement,” or the specific plan name.

Pre-tax vs. Roth: Traditional (pre-tax) contributions reduce your taxable income — you pay less federal income tax now, but you’ll pay taxes when you withdraw in retirement. Roth contributions come from after-tax dollars — no tax break now, but withdrawals in retirement are tax-free.

2026 contribution limits:

• Under 50: $24,500 per year
• Age 50–59 or 64+: $32,500 ($24,500 + $8,000 catch-up)
• Age 60–63: $35,750 ($24,500 + $11,250 super catch-up)

See the official IRS 401(k) limit announcement.

Tax impact: A traditional 401(k) contribution is one of the most powerful deductions available. If you contribute $500 per paycheck pre-tax and you’re in the 22% bracket, you save $110 in federal income tax per paycheck — meaning the $500 contribution only “costs” you $390 in take-home pay.

8. Health Insurance Premiums

What it is: Your share of employer-sponsored medical, dental, and vision insurance. Most employers cover 70–85% of the premium; you pay the remainder through payroll deductions.

Tax treatment: Under a Section 125 cafeteria plan, employer health insurance premiums are deducted pre-tax — meaning they bypass federal income tax, Social Security, and Medicare. This makes health insurance premiums one of the most tax-efficient deductions on your paycheck.

Typical amounts: According to the Kaiser Family Foundation, the average employee contribution for employer health insurance in 2025 was approximately:

• Single coverage: $130/month ($60/biweekly)
• Family coverage: $530/month ($245/biweekly)

Your actual amount depends on your employer’s plan and the tier (single, employee + spouse, family).

9. Health Savings Account (HSA)

What it is: A tax-advantaged savings account available to employees enrolled in a high-deductible health plan (HDHP). Contributions are deducted from your paycheck pre-tax.

Triple tax advantage: HSA contributions are exempt from federal income tax and FICA taxes. Investment growth inside the HSA is tax-free. Withdrawals for qualified medical expenses are also tax-free. No other account in the U.S. tax code offers this triple benefit.

2026 contribution limits:

• Self-only: $4,400
• Family: $8,750
• Catch-up (55+): Additional $1,000

10. Flexible Spending Account (FSA)

What it is: An employer-sponsored account that lets you set aside pre-tax dollars for healthcare expenses (Healthcare FSA) or dependent care (Dependent Care FSA).

2026 limits:

• Healthcare FSA: $3,300
• Dependent Care FSA: $5,000 (or $2,500 if married filing separately)

Key difference from HSA: FSA funds generally follow a “use it or lose it” rule — unused funds at year-end are forfeited, though some plans allow a $640 rollover or a 2.5-month grace period. HSA funds roll over indefinitely.

11. Life & Disability Insurance

What it is: Many employers provide basic group life insurance (often 1× your annual salary) at no cost. If you elected supplemental life insurance, accidental death & dismemberment (AD&D), or short-term/long-term disability coverage, those premiums appear as payroll deductions.

Tax treatment: Employer-paid group term life insurance up to $50,000 of coverage is tax-free to you. Coverage above $50,000 creates “imputed income” — a small taxable amount added to your gross pay (you’ll see it on your stub but it’s not actual cash).

12. Other Common Deductions

Beyond the major items above, you may see additional lines on your pay stub:

• Union dues — Required if you’re in a unionized workplace. Deducted post-tax.
• Commuter benefits — Pre-tax transit or parking deductions (up to $325/month in 2026).
• Student loan repayment — Some employers offer student loan repayment as a benefit, deducted from your paycheck.
• Charitable contributions — Payroll-deducted donations to United Way or similar organizations.
• Wage garnishments — Court-ordered deductions for child support, back taxes, or debt collection. These are mandatory and your employer has no choice but to comply.
• Roth IRA (payroll) — Some employers facilitate after-tax Roth IRA contributions directly via payroll.

Putting It All Together: A Real Paycheck Example

Let’s trace a complete paycheck for a worker earning $75,000/year in Texas (no state income tax), paid biweekly (26 paychecks), with a 6% traditional 401(k) contribution and single health insurance:

In this example, the worker takes home 73.4% of their gross salary. The biggest single chunk — federal income tax at $307/check — could be reduced by increasing the 401(k) contribution or adjusting the W-4.

Which Deductions Can You Actually Control?

Here’s a quick reference for what you can change — and what you’re stuck with:

How to Check If Your Deductions Are Correct

Payroll errors happen more often than you’d think — a wrong filing status on your W-4, a missed benefit election, or a duplicate deduction can cost you hundreds of dollars per year. Here’s how to audit your paycheck:

1. Compare your W-4 to your withholding. Does your pay stub filing status match what you filed? If you’re married but your stub shows “Single,” you’re overwithholding.
2. Verify your 401(k) percentage. Multiply your gross pay by your elected percentage. Does the deducted amount match?
3. Check health insurance against your benefits summary. Your benefits enrollment confirmation shows your per-pay-period premium — compare it to what’s on your stub.
4. Look for imputed income. If you see a line labeled “Group Life Imputed” or similar, it’s the taxable value of employer-provided life insurance above $50,000. It increases your gross but isn’t actual cash.
5. Watch for year-end changes. Social Security stops at $176,100, so your late-year paychecks may be larger. New calendar years reset all caps and may introduce new benefit rates.

Frequently Asked Questions

How much of my paycheck goes to taxes?

For most workers, mandatory taxes (federal income tax + FICA + state tax) consume 20–35% of gross pay. The exact percentage depends on your income bracket, filing status, and state. Workers in no-income-tax states like Texas, Florida, and Nevada pay only federal + FICA (~15–25%). Use our paycheck calculator for your exact number.

Why is so much taken out of my first paycheck?

First paychecks often look smaller because (1) you may have started mid-pay-period, so you’re only being paid for a partial period, (2) your W-4 may default to single with no adjustments, causing higher withholding, and (3) one-time benefit deductions (like first-month health insurance) can stack up. Read our full explanation: why is my paycheck lower than my salary?

Are pre-tax deductions worth it?

Yes — pre-tax deductions (401(k), HSA, health insurance) reduce your taxable income, which means you pay less in federal income tax and sometimes less in FICA. A $500/month pre-tax 401(k) contribution in the 22% bracket saves you $110/month in federal taxes alone. The money isn’t “gone” — it’s in your retirement account earning compound returns.

What is the difference between pre-tax and post-tax deductions?

Pre-tax deductions (401(k), health insurance, HSA, FSA) are subtracted from your gross pay before taxes are calculated, reducing your taxable income. Post-tax deductions (Roth 401(k), union dues, garnishments, some life insurance) are subtracted after taxes — they don’t reduce your current tax bill, but some (like Roth contributions) provide tax-free income later.

Can I stop my employer from taking out taxes?

No. Federal law requires employers to withhold federal income tax (based on your W-4) and FICA taxes (Social Security + Medicare) from every paycheck. State law requires state tax withholding where applicable. You can adjust federal withholding by updating your W-4, but you cannot eliminate it entirely if you earn taxable wages.

Bottom Line

Your paycheck is smaller than your salary because of a stack of mandatory taxes and voluntary benefit deductions that sit between your gross earnings and your bank deposit. The mandatory layer — federal income tax, Social Security (6.2%), and Medicare (1.45%) — is unavoidable. But the voluntary layer — 401(k), health insurance, HSA — is actually working in your favor by reducing your taxes and building long-term wealth.

The most valuable thing you can do is understand each line on your pay stub and make sure the amounts match your elections. Even small payroll errors compound over 26 paychecks.
