You got the job offer, you saw the salary number, and you did the mental math: divide by 26 paydays, and that’s what lands in your bank account. Then your first real pay stub arrives and it’s… smaller. Not a little smaller. Noticeably smaller.
That’s normal. Your gross pay and your take-home pay live in different worlds, and the gap between them is a line-by-line list of taxes and deductions. Let’s walk through every line on a real pay stub.
Gross pay vs. net pay: the two numbers that matter
Gross pay is the full amount earned before anything is taken out. On $65,000 a year paid biweekly (26 pay periods), gross per paycheck is $2,500.
Net pay (take-home pay) is what hits your bank account after taxes and deductions.
Federal income tax: the biggest variable
Your employer withholds an estimated amount from every paycheck based on your Form W-4. The tax is progressive: the 10% rate applies only to the first chunk of income, then 12%, then 22%, and so on. Moving into a higher bracket taxes only the dollars above the cutoff — not all your income.
Before brackets apply, you get the standard deduction ($15,000 for single filers in 2025 — the IRS adjusts this most years, so check the current figure).
FICA taxes: Social Security and Medicare
Social Security: 6.2%
6.2% of wages up to the annual wage cap ($176,100 for 2025). Your employer matches it out of their own pocket.
Medicare: 1.45%
A flat 1.45% of all wages — no cap. High earners pay an additional 0.9% surtax above $200,000 (single).
State and local taxes: it depends where you live
Texas, Florida, Washington and a few others have no state income tax — this line will be missing entirely. Others charge flat or progressive rates. City or county taxes can appear in certain metro areas.
Pre-tax vs. post-tax deductions: the order matters
Pre-tax deductions (before taxes are calculated)
- 401(k) contributions — lowers the income your federal tax is calculated on.
- Health, dental, and vision premiums — usually pre-tax through a cafeteria plan.
- HSA or FSA contributions — pre-tax as well.
Post-tax deductions (after taxes)
- Roth 401(k) contributions — taxed now, tax-free later.
- Supplemental life or disability insurance.
- Union dues, charitable giving, wage garnishments.
The full walkthrough: $65,000 salary, biweekly, single filer
Assumptions: $65,000 salary → $2,500 gross per paycheck; single, $15,000 standard deduction (2025 figure); pre-tax: 6% 401(k) + $90 health; state tax 5% sample rate; post-tax $18 dental/vision.
Step 1 — pre-tax off the top: 401(k) $150.00 + health $90.00 = $240.00. Pay after pre-tax: $2,260.00.
Step 2 — federal tax: annual taxable $65,000 − $3,900 − $2,340 − $15,000 = $43,760. Tax = 10% × $11,925 ($1,192.50) + 12% × $31,835 ($3,820.20) = $5,012.70/year → $192.80 per paycheck.
Step 3 — FICA: Social Security 6.2% × $2,500 = $155.00; Medicare 1.45% × $2,500 = $36.25. Total FICA: $191.25.
Step 4 — state + post-tax: state 5% × $2,500 = $125.00; dental/vision $18.00.
Step 5 — net pay: $2,500 − $150 − $90 − $192.80 − $125 − $155 − $36.25 − $18 = $1,732.95.
A $65,000 salary becomes about $1,733 every two weeks — roughly $45,057 a year take-home. Run your own numbers with our free paycheck calculator.
How to keep more of each paycheck (legitimately)
Max out pre-tax benefits. 401(k), HSA, FSA shrink taxable income dollar for dollar — and get the full employer 401(k) match.
Check your W-4. Huge refund = over-withholding (interest-free loan to the government). Owing every April = under-withholding. Try our US income tax calculator for the annual view.
Review your stub twice a year. Wrong state withholding after a move, lapsed HSA elections, premium increases — catch them early.

FAQs
Why is my first paycheck smaller than I expected?
Your offer quoted gross salary; your bank gets net pay after federal tax, FICA, state tax, and benefits. A $65,000 salary typically nets around $45,000 a year.
What’s the difference between pre-tax and post-tax deductions?
Pre-tax (traditional 401(k), health premiums) comes out before income tax is calculated, lowering your tax bill. Post-tax (Roth 401(k), union dues) comes out of already-taxed dollars.
How much are Social Security and Medicare per paycheck?
Social Security: 6.2% up to the wage cap; Medicare: 1.45% of all wages. On $2,500 biweekly: $155.00 + $36.25.
Can I reduce taxes taken from my paycheck?
Increase pre-tax contributions (401(k), HSA, FSA) and make sure your W-4 matches your situation. Review your stub twice a year.
Do all states take income tax?
No — Texas, Florida, Washington and others have none. State tax is a big reason the same salary feels different across states.
