Your pay stub contains crucial information — but most people just glance at the net pay and move on. Understanding every line helps you verify accuracy, optimize taxes, and catch errors (which happen more often than you’d think).
Anatomy of a Pay Stub (Main Sections)
Every pay stub has these core sections:
| Section | What It Shows |
|---|---|
| Personal/Company Info | Your name, address, SSN (last 4), employer name, pay period dates |
| Earnings | Gross pay (before deductions), overtime, bonuses, commission |
| Taxes | Federal income tax, FICA (Social Security + Medicare), state/local tax |
| Pre-Tax Deductions | 401(k), health insurance, FSA/HSA, commuter benefits |
| Post-Tax Deductions | Roth 401(k), disability insurance (some), garnishments |
| Net Pay | Take-home pay (what hits your bank account) |
| YTD (Year-to-Date) Totals | Cumulative amounts from Jan 1 to current pay period |
Section 1: Personal & Pay Period Info
Top of pay stub:
| Field | Example | What It Means |
|---|---|---|
| Employee Name | John Smith | You |
| Employee ID | 12345 | Internal company number |
| SSN | XXX-XX-6789 | Last 4 digits (for privacy) |
| Pay Period | 01/01/2026 - 01/15/2026 | Dates this paycheck covers |
| Pay Date | 01/20/2026 | When money hits your account |
| Pay Frequency | Biweekly (every 2 weeks) | 26 paychecks/year |
Pay frequencies:
| Frequency | Paychecks/Year | Example |
|---|---|---|
| Weekly | 52 | Every Friday |
| Biweekly | 26 | Every other Friday |
| Semi-monthly | 24 | 1st and 15th of month |
| Monthly | 12 | Last day of month |
Why it matters: If biweekly, you get 26 paychecks (not 24) → 2 months/year you get 3 paychecks. Budget accordingly.
Section 2: Earnings (Gross Pay)
This is your pay BEFORE deductions.
| Line Item | Current | YTD | Explanation |
|---|---|---|---|
| Regular Pay | $3,000.00 | $6,000.00 | Base salary for pay period |
| Overtime | $225.00 | $450.00 | Hourly rate × 1.5 × OT hours |
| Bonus | $0.00 | $5,000.00 | One-time bonuses (quarterly, annual) |
| Commission | $500.00 | $1,000.00 | Sales commissions |
| PTO Payout | $0.00 | $0.00 | Unused PTO cashed out |
| Other | $0.00 | $0.00 | Relocation, stipends, etc. |
| GROSS PAY | $3,725.00 | $12,450.00 | Total before deductions |
How Gross Pay is Calculated
Salaried employees:
Annual salary ÷ Pay periods = Gross pay
| Annual Salary | Pay Frequency | Gross Pay/Paycheck |
|---|---|---|
| $50,000 | Biweekly (26) | $1,923 |
| $75,000 | Biweekly (26) | $2,885 |
| $100,000 | Biweekly (26) | $3,846 |
| $50,000 | Semi-monthly (24) | $2,083 |
| $75,000 | Semi-monthly (24) | $3,125 |
Hourly employees:
Hourly rate × Hours worked = Regular pay
Hourly rate × 1.5 × Overtime hours = Overtime pay
Example:
- Hourly rate: $25/hr
- Hours worked: 80 regular, 10 overtime
- Regular pay: $25 × 80 = $2,000
- Overtime pay: $25 × 1.5 × 10 = $375
- Gross pay: $2,375
Verify Your Gross Pay
Check for errors:
| What to Verify | How | Why |
|---|---|---|
| Salary matches offer letter | $75k salary ÷ 26 = $2,885/paycheck | Companies make errors (wrong pay scale entered) |
| Hours accurate (hourly) | Compare to timesheet | Missed hours = missed pay |
| Overtime calculated correctly | Should be 1.5× regular rate | Sometimes miscalculated as regular rate |
| Bonuses/commissions | Match what was promised | Ensure you got full amount |
If gross pay is wrong, contact payroll immediately. Most companies have deadlines to correct (30-60 days).
Section 3: Taxes (Federal, FICA, State)
This is where most of your money disappears.
| Tax | Current | YTD | Rate | What It Funds |
|---|---|---|---|---|
| Federal Income Tax | $406.00 | $1,360.00 | 10-37% | IRS, federal government operations |
| Social Security | $230.95 | $772.00 | 6.2% | Social Security benefits (retirement) |
| Medicare | $54.01 | $181.00 | 1.45% | Medicare (healthcare for 65+) |
| State Income Tax | $186.25 | $623.00 | 0-13% | State government (varies by state) |
| Local Tax | $37.25 | $125.00 | Varies | City/county (not all areas) |
| TOTAL TAXES | $914.46 | $3,061.00 | ~25% |
Federal Income Tax Withholding
How much is withheld depends on:
- Your gross pay
- W-4 form (filing status, dependents, additional withholding)
- Tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%)
2026 Federal Tax Brackets (Single):
| Income | Tax Rate | Tax Owed |
|---|---|---|
| $0 - $11,600 | 10% | $1,160 |
| $11,601 - $47,150 | 12% | + $4,266 |
| $47,151 - $100,525 | 22% | + $11,743 |
| $100,526 - $191,950 | 24% | + $21,942 |
| $191,951 - $243,725 | 32% | + $16,568 |
| $243,726 - $609,350 | 35% | + $127,969 |
| $609,351+ | 37% | + additional |
Example (Single, $75,000 salary):
- $11,600 × 10% = $1,160
- ($47,150 - $11,600) × 12% = $4,266
- ($75,000 - $47,150) × 22% = $6,127
- Total federal tax: $11,553/year (~15.4% effective rate)
- Per paycheck (biweekly): $11,553 ÷ 26 = $444
If your withholding is off:
| Your Situation | Action |
|---|---|
| Owe $5,000+ at tax time | Increase withholding (fill new W-4, claim fewer allowances) |
| Get $5,000+ refund | Decrease withholding (you’re giving IRS interest-free loan) |
| Target: Owe $0-$1,000 | Optimal (not huge refund, not huge bill) |
Update W-4 anytime: Ask HR for new form, adjust allowances.
FICA Tax (Social Security + Medicare)
FICA = 7.65% of gross pay (up to Social Security wage base).
| Tax | Rate | 2026 Wage Base | Max Annual | Per Paycheck (biweekly) |
|---|---|---|---|---|
| Social Security | 6.2% | $168,600 | $10,453 | $402 max |
| Medicare | 1.45% | No limit | Unlimited | Varies |
| Additional Medicare (high earners) | 0.9% | Over $200k (single) / $250k (married) | Varies | On income over threshold |
Key facts:
- You pay 7.65%, employer pays 7.65% (total 15.3%)
- Social Security caps at $168,600 (in 2026) → If you earn $168,600+, you stop paying SS tax mid-year
- Medicare has NO cap → Paid on all income forever
Example ($75,000 salary):
- Social Security: $75,000 × 6.2% = $4,650/year ($179/paycheck)
- Medicare: $75,000 × 1.45% = $1,088/year ($42/paycheck)
- Total FICA: $5,738/year ($221/paycheck)
FICA is NOT refundable → Unlike federal income tax (which can be refunded), FICA is gone forever.
State Income Tax
Varies by state:
| State Type | States | Tax Rate |
|---|---|---|
| No income tax | AK, FL, NV, SD, TN, TX, WA, WY | 0% |
| Low tax | ND, PA, IN | 2-4% |
| Moderate tax | CO, IL, MI, OH | 4-6% |
| High tax | CA, NY, NJ, HI MN | 7-13% |
Example (California, $75,000 salary):
- CA tax: ~$4,500/year (~6% effective)
- Per paycheck: $173
If you live in one state, work in another:
- Usually pay tax to work state
- File returns in both states
- Get credit in home state for taxes paid to work state
Local Income Tax
Some cities/counties have additional tax:
| Location | Local Tax Rate | Example |
|---|---|---|
| New York City | 3-4% | On top of NY state 4-10% |
| Philadelphia | 3.8% | On top of PA 3% |
| San Francisco | 0% | No local tax (but high state) |
| Most of US | 0% | No local income tax |
Check your pay stub: If you see “Local” or “City” tax, that’s it.
Section 4: Pre-Tax Deductions (Reduce Taxable Income)
These come OUT of your paycheck BEFORE taxes are calculated → Lower your taxable income.
| Deduction | Current | YTD | Annual Limit (2026) | Tax Savings |
|---|---|---|---|---|
| 401(k) Traditional | $500.00 | $2,000.00 | $23,500 | Pay no taxes on this now |
| Health Insurance | $150.00 | $600.00 | N/A | Save ~30% in taxes |
| Dental Insurance | $15.00 | $60.00 | N/A | Pre-tax |
| Vision Insurance | $5.00 | $20.00 | N/A | Pre-tax |
| FSA (Flexible Spending) | $125.00 | $500.00 | $3,200 | Pre-tax medical expenses |
| HSA (Health Savings) | $200.00 | $800.00 | $4,150 (individual) / $8,300 (family) | Triple tax-advantaged |
| Commuter Benefits | $100.00 | $400.00 | $315/month | Pre-tax transit/parking |
| TOTAL PRE-TAX | $1,095.00 | $4,380.00 | Saves $300-$400 in taxes |
401(k) Contributions
Traditional 401(k):
- ✅ Reduces taxable income NOW
- ✅ Grows tax-deferred
- ❌ Taxed when you withdraw (in retirement)
Roth 401(k):
- ❌ Doesn’t reduce taxable income now
- ✅ Grows tax-free
- ✅ Withdrawals tax-free (in retirement)
2026 Limits:
| Account | Limit | Catch-Up (age 50+) |
|---|---|---|
| 401(k) | $23,500 | + $7,500 |
| IRA (separate) | $7,000 | + $1,000 |
How much to contribute:
| Strategy | Contribution | Why |
|---|---|---|
| Minimum | Match only (e.g., 4%) | Free money from employer |
| Good | 10-15% | Solid retirement savings |
| Aggressive | 20%+ or $23,500 max | Retire early, build wealth fast |
Example:
- Salary: $75,000
- Contribute: 15% = $11,250/year
- Per paycheck (biweekly): $433
Tax savings:
- $11,250 not taxed at 22% bracket = $2,475 saved in taxes
Health Insurance
Premiums often deducted pre-tax.
Typical costs (2026):
| Plan Type | Employee Cost (Monthly) | Annual |
|---|---|---|
| Individual | $100-$300 | $1,200-$3,600 |
| Family | $400-$800 | $4,800-$9,600 |
Shows on pay stub as:
- Medical: $150 (per paycheck, biweekly = $300/month)
Verify:
- Does amount match plan you chose during open enrollment?
- Did premiums increase (usually Jan 1)?
FSA & HSA (Medical Savings Accounts)
| Account | What It Is | Limit (2026) | Tax Benefit |
|---|---|---|---|
| FSA | Flexible Spending (use-it-or-lose-it) | $3,200 | Pre-tax contributions, pre-tax spending |
| HSA | Health Savings (rolls over forever) | $4,150 (individual) / $8,300 (family) | Pre-tax contributions, tax-free withdrawals, tax-free growth |
HSA = Best tax deal:
- Contribute pre-tax (save ~30%)
- Grow tax-free (invest it!)
- Withdraw tax-free (for medical expenses)
Example (HSA):
- Contribute $4,150/year
- Tax savings (22% bracket): $913
- Invest in S&P 500 (10%/year)
- 30 years: $4,150 → $68,000 (tax-free for medical)
Section 5: Post-Tax Deductions
These come OUT of paycheck AFTER taxes are calculated → Don’t reduce taxable income.
| Deduction | Current | YTD | Why Post-Tax |
|---|---|---|---|
| Roth 401(k) | $200.00 | $800.00 | Already taxed, grows tax-free |
| Disability Insurance (some) | $15.00 | $60.00 | Optional add-on coverage |
| Life Insurance (voluntary) | $10.00 | $40.00 | Above employer-provided $50k |
| Union Dues | $50.00 | $200.00 | Required if in union |
| Loan Repayment (401k loan) | $100.00 | $400.00 | Repaying loan from your 401k |
| Garnishment | $250.00 | $1,000.00 | Court-ordered (child support, debt) |
| Charitable Giving | $25.00 | $100.00 | Payroll donation to charity |
| TOTAL POST-TAX | $650.00 | $2,600.00 |
Garnishments (Court-Ordered Deductions)
If you see “Garnishment” on pay stub:
| Type | What It Is | Limit |
|---|---|---|
| Child support | Court-ordered support for children | Up to 50-65% of disposable income |
| Student loan (default) | Federal student loan in default | Up to 15% of disposable income |
| Tax levy | IRS or state tax owed | Varies (can be large) |
| Creditor garnishment | Court judgment from lawsuit | Up to 25% of disposable income |
Disposable income = Gross pay - required deductions (taxes, SS, Medicare)
Can’t stop garnishment without:
- Paying debt in full
- Negotiating settlement
- Filing bankruptcy
- Proving financial hardship (rare)
Section 6: Net Pay (Take-Home Pay)
This is what hits your bank account.
| Calculation | Example |
|---|---|
| Gross Pay | $3,725.00 |
| - Taxes | -$914.46 |
| - Pre-Tax Deductions | -$1,095.00 |
| - Post-Tax Deductions | -$650.00 |
| = NET PAY | $1,065.54 |
Net pay is typically 60-80% of gross pay.
| Gross Pay | Typical Net Pay (70-75%) | After All Deductions |
|---|---|---|
| $3,000 | $2,100-$2,250 | ~70-75% |
| $4,000 | $2,800-$3,000 | ~70-75% |
| $5,000 | $3,500-$3,750 | ~70-75% |
Factors that lower net pay %:
- High tax state (CA, NY: ~65% net)
- High 401(k) contribution (15-20%: ~60-65% net)
- Expensive health insurance (family plan: ~60-70% net)
- Garnishments: ~50-60% net
Section 7: Year-to-Date (YTD) Totals
Running totals from January 1 to current pay period.
| Item | YTD | Why It Matters |
|---|---|---|
| Gross Pay | $72,500 | Verify you’re on track for annual salary |
| Federal Tax | $11,150 | Check withholding (should be ~15% for $75k earner) |
| Social Security | $4,495 | Monitor if approaching $168,600 wage base |
| Medicare | $1,051 | Always 1.45% of gross |
| 401(k) | $12,000 | Track toward $23,500 annual limit |
| HSA | $3,000 | Track toward $4,150 limit (individual) |
How to use YTD:
1. Verify Annual Salary on Track
Formula: YTD Gross ÷ Pay periods so far = Average per paycheck
Example (mid-year check):
- Expected salary: $75,000
- Pay periods so far: 13 (26 weeks into year)
- YTD gross should be: $75,000 ÷ 26 × 13 = $37,500
- If YTD shows $35,000 → You’re underpaid by $2,500 → Contact payroll
2. Check Tax Withholding
Estimate annual tax owed, compare to YTD withheld.
Example:
- Salary: $75,000 (single)
- Expected federal tax: ~$11,500
- Mid-year (13 paychecks): Should have withheld ~$5,750
- If YTD shows $7,000 withheld → Withholding too much → Update W-4 (or enjoy big refund)
- If YTD shows $4,000 withheld → Withholding too little → Increase withholding (or owe at tax time)
You want to owe $0-$1,000 at tax time (not get $5,000 refund = interest-free loan to IRS).
3. Monitor 401(k) Contribution Pace
Check if you’ll hit annual limit.
Example:
-Goal: Max 401(k) ($23,500)
- Pay periods: 26/year
- Need to contribute: $23,500 ÷ 26 = $904/paycheck
- Mid-year check: 13 paychecks × $904 = $11,752 YTD expected
- If YTD shows $8,000 → You’re behind → Increase contribution %
Common Pay Stub Errors (And How to Spot Them)
| Error | How to Spot | Example | Fix |
|---|---|---|---|
| Wrong hourly rate | Divide regular pay by hours | Should be $25/hr, calc shows $23/hr | Contact payroll, show math |
| Missed overtime | Check hours vs. OT pay | Worked 10 OT hours, only paid for 5 | Provide timesheet, request correction |
| Incorrect tax withholding | Compare to tax calculator | Withholding 30% but should be 20% | Submit new W-4 form |
| Double deduction | See same deduction twice | Health insurance $150 shows twice | Payroll error, request refund |
| Wrong pay period | Dates don’t match schedule | Paid for 1/1-1/15 but should be 1/16-1/31 | Notify payroll immediately |
| Missing bonus | Promised $5k, not on stub | No bonus line item | Email from manager re: bonus → send to payroll |
Payroll errors happen. Check every pay stub, especially:
- First paycheck (setup errors common)
- After promotion/raise
- After changing benefits
- After bonus/commission
Most companies have 30-60 day window to report errors. Don’t wait.
How to Calculate Your Effective Tax Rate
Effective rate = Total taxes ÷ Gross pay
Example ($75,000 salary):
| Tax Type | Annual Amount |
|---|---|
| Federal income tax | $11,500 |
| FICA (SS + Medicare) | $5,738 |
| State tax (say, 5%) | $3,750 |
| Total taxes | $20,988 |
Effective tax rate: $20,988 ÷ $75,000 = 28%
Compare to your paycheck:
- Gross: $3,000
- Taxes: $840
- Effective rate: $840 ÷ $3,000 = 28% ✅ Matches
If doesn’t match, investigate why.
Tax Withholding: How to Optimize
Goal: Owe $0-$1,000 at tax time (not huge refund, not huge bill).
If You Owe Money Every Year
You’re under-withholding.
How to fix:
- Submit new W-4 to employer
- Claim fewer allowances (or add extra $ withholding)
- Example: Add $100/paycheck extra withholding
If You Get Huge Refund Every Year
You’re over-withholding (giving IRS interest-free loan).
How to fix:
- Submit new W-4
- Claim more allowances
- Adjust so you owe ~$500 (or break even)
Better use: Invest that $5,000 refund monthly throughout year → Earn $300-$500 in market returns
Bottom Line
Your pay stub tells the story of where your money goes.
Key sections:
- Gross pay (salary ÷ pay periods)
- Federal tax (~10-25% depending on income)
- FICA (7.65% up to SS wage base)
- State/local tax (0-13% depending on state)
- Pre-tax deductions (401k, HSA, health insurance)
