How to Read Your Paycheck: Withholdings, Deductions, and Take-Home Pay Explained

The salary in your offer letter and the amount that actually lands in your bank account are almost never the same number, and the gap can be a genuine shock the first time you see it. Between the two sits your paycheck: a dense grid of abbreviations, tax lines, and deductions that most people glance at once and never decode. That is a missed opportunity, because your pay stub is one of the most useful financial documents you own. It shows exactly where your money goes before you ever see it, whether you are withholding the right amount of tax, and how much your benefits really cost. This guide walks through every major part of a US paycheck: gross pay, the taxes taken out, pre- and after-tax deductions, and the take-home pay at the bottom, so you can read yours with confidence.

Gross pay vs. net pay: the two numbers that matter

Every paycheck tells a story that runs from top to bottom, and it begins with gross pay: your total earnings for the pay period before anything is subtracted. For a salaried worker, gross pay is your annual salary divided by the number of pay periods in the year (for example, a $60,000 salary paid twice a month is $2,500 of gross pay per check). For an hourly worker, it is your hourly rate times hours worked, plus any overtime, bonuses, tips, or commissions.

At the very bottom of the stub is net pay, often labeled "take-home pay." This is what remains after every tax and deduction has been removed, and it is the amount actually deposited in your account. The distance between gross and net is where the real education happens. For many workers, net pay lands somewhere around 70% to 85% of gross, but the exact figure depends on your tax situation, your state, and how much you route into benefits. Learning to read the lines in between is what turns a confusing stub into a budgeting tool, because your take-home pay, not your salary, is the number your budget should actually be built on. That is why popular frameworks like the 50/30/20 budget start from your real, after-tax income rather than the headline salary.

The taxes withheld from every paycheck

The largest bite out of most paychecks is taxes, and they arrive in a few distinct forms.

Federal income tax is withheld from each check as an estimated prepayment toward your annual federal tax bill. Your employer calculates the amount using the information on your Form W-4 and the IRS withholding tables. Because it is only an estimate, the goal is to have your total withholding for the year land close to what you actually owe.

FICA taxes fund Social Security and Medicare, and they are not optional. Under the Federal Insurance Contributions Act, they split into two parts. The IRS summarizes the current rates in Topic No. 751:

• Social Security tax of 6.2% of your wages, up to an annual wage base limit that the Social Security Administration adjusts each year. Earnings above that cap are not subject to Social Security tax; confirm the current limit on the SSA's contribution and benefit base page.
• Medicare tax of 1.45% of all your wages, with no cap.
• An Additional Medicare Tax of 0.9% applies to wages above $200,000 in a calendar year. Employers begin withholding it once your pay crosses that threshold, regardless of your filing status, as explained in the IRS's Additional Medicare Tax guidance.

State and local income taxes may also appear, depending on where you live and work. A handful of states levy no income tax at all, while some cities and counties add a local tax of their own. These lines follow the same logic as federal withholding: an estimated prepayment toward a year-end bill.

Tax	Rate (employee share)	Applies to	Annual cap
Social Security	6.2%	Wages up to the wage base limit	Yes, adjusts yearly
Medicare	1.45%	All wages	No cap
Additional Medicare	0.9%	Wages over $200,000	Applies only above the threshold
Federal income tax	Varies (set by your W-4)	Taxable wages	No fixed cap

Your Form W-4 controls the withholding

If your refund or tax bill each spring feels random, your Form W-4 is usually the reason. This is the form you complete when you start a job, and can update anytime, that tells your employer how much federal income tax to withhold. Since a 2020 redesign, the W-4 no longer uses "allowances." Instead it asks about your filing status, whether you hold multiple jobs or have a working spouse, dependents you can claim, other income, deductions, and any extra amount you want withheld. The IRS explains each step on its About Form W-4 page.

The key idea is balance. Withhold too little and you may face a bill, and possibly an underpayment penalty, when you file. Withhold too much and you hand the government an interest-free loan all year, only to get it back as a refund. A large refund feels good, but it means your paychecks were smaller than they needed to be every single pay period. To dial it in, run your numbers through the free IRS Tax Withholding Estimator, especially after a raise, marriage, new child, or second job, then submit an updated W-4 if needed. Getting this right is a quiet but powerful part of learning how to automate your finances, because it keeps more of your own money working for you throughout the year instead of parked with the IRS.

Pre-tax deductions: benefits that lower your taxable income

After taxes, the next cluster of lines covers deductions: money routed to benefits and savings before your check is finalized. The most valuable of these are pre-tax deductions, which are subtracted from your gross pay before income tax is calculated, lowering the wages that get taxed.

Common pre-tax deductions include:

• Traditional 401(k) or 403(b) contributions. Money you defer into a traditional workplace retirement plan is not subject to federal income tax now; you pay tax later when you withdraw in retirement. One subtlety worth knowing: these contributions still have Social Security and Medicare tax taken out. The IRS's 401(k) contribution limit page lists the annual maximums, which change over time. Whether pre-tax or Roth is the better home for your savings is its own decision, covered in our guide to Roth vs. traditional accounts.
• Health, dental, and vision insurance premiums. When paid through an employer's Section 125 plan, these typically come out pre-tax, often escaping both income and FICA taxes.
• Health Savings Account (HSA) and Flexible Spending Account (FSA) contributions. Payroll HSA contributions can be exempt from income and FICA taxes, one reason the account is so tax-efficient; see our explainer on what an HSA is. The IRS covers the rules in Publication 969.

Because these deductions shrink your taxable wages, they lower your income tax bill while directing money toward retirement, healthcare, or savings. That is why funding them is often the most tax-efficient move on the entire stub.

After-tax deductions and the other line items

Not everything comes out before taxes. After-tax (post-tax) deductions are subtracted from your pay after taxes have already been calculated, so they do not reduce your taxable income. Common examples include:

• Roth 401(k) contributions, made with after-tax dollars in exchange for tax-free qualified withdrawals later.
• Union dues, some insurance premiums (such as certain life or disability coverage), and charitable contributions made through payroll.
• Wage garnishments: court-ordered deductions for obligations like child support or unpaid debts, which employers are legally required to withhold.

You will also see year-to-date (YTD) columns next to many lines. These running totals, YTD gross, YTD taxes, YTD deductions, are more useful than they look. They let you verify you are on track with retirement contributions, see how close you are to the Social Security wage cap, and gather the numbers you need at tax time. Glancing at your YTD figures once a quarter is a simple habit that catches payroll errors before they compound.

How to read your pay stub line by line

Put it all together and a pay stub follows a predictable structure, even though every employer's format looks a little different. From top to bottom, you will generally find:

1. Earnings: your gross pay for the period, often broken into regular, overtime, bonus, and similar categories, with hours listed for hourly workers.
2. Taxes withheld: federal income tax, Social Security, Medicare, and any state or local taxes.
3. Deductions: pre-tax items (retirement, health premiums, HSA/FSA) and after-tax items, each on its own line.
4. Net pay: the take-home amount deposited to your account.
5. YTD totals: running annual figures for earnings, taxes, and deductions.

A few things are worth checking every so often. Confirm your filing status and name are correct, make sure your retirement contributions match what you elected, and watch for any deduction you do not recognize. If something looks off, your employer's HR or payroll department is the right first stop. Reading your stub this closely a couple of times a year is one of the easiest ways to catch mistakes and to genuinely understand where your money goes each month before it ever reaches your checking account.

Key takeaways

• Your gross pay is your total earnings; your net (take-home) pay is what lands in your account after taxes and deductions, and your budget should be built on the take-home figure.
• Mandatory FICA taxes are 6.2% Social Security (up to an annual wage cap) and 1.45% Medicare (no cap), plus a 0.9% Additional Medicare Tax on wages over $200,000.
• Your Form W-4 controls federal income tax withholding; aim to withhold close to what you owe rather than chasing a big refund, and revisit the IRS Tax Withholding Estimator after major life changes.
• Pre-tax deductions (traditional 401(k), health premiums, HSA/FSA) lower your taxable income; after-tax deductions (Roth 401(k), garnishments) do not.
• Review your year-to-date totals a few times a year to catch payroll errors and track your retirement and tax progress.

Frequently asked questions

Why is my take-home pay so much lower than my salary?

Because several layers come out before you ever see the money: federal income tax, Social Security and Medicare (FICA) taxes, any state and local income taxes, and your own elected deductions for retirement, health insurance, and similar benefits. Together these commonly reduce a paycheck to roughly 70% to 85% of gross pay, though your exact take-home depends on your state, income, and how much you contribute to pre-tax benefits.

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

Pre-tax deductions come out of your pay before income tax is calculated, so they lower your taxable wages and reduce your tax bill; traditional 401(k) contributions and employer health premiums are common examples. After-tax deductions come out after taxes are figured, so they do not reduce your taxable income. Roth 401(k) contributions and wage garnishments fall into this second group.

How do I change how much tax is withheld from my paycheck?

Submit an updated Form W-4 to your employer. To find the right numbers, use the free IRS Tax Withholding Estimator, which factors in your income, filing status, and any other jobs or income. It is smart to revisit your W-4 after a raise, a marriage or divorce, a new child, or taking on a second job, since each of these changes what you will owe.

What does FICA mean on my pay stub?

FICA stands for the Federal Insurance Contributions Act, the law that funds Social Security and Medicare through payroll taxes. Your share is 6.2% for Social Security (up to an annual wage base limit) and 1.45% for Medicare (on all wages), with an extra 0.9% Medicare tax on very high earnings. Your employer pays a matching amount for Social Security and regular Medicare that does not appear on your stub.
