Money at Work: Understand Your Paycheck and Keep More of It
Where Did My Paycheck Go?
You worked 80 hours. You know your hourly rate. But when your paycheck arrives, it is much smaller than you expected. Where did all that money go?
Your pay stub has the answers. Learning to read it can help you catch mistakes, find money you did not know you had, and keep more of what you earn. Many workers also miss tax credits worth hundreds or even thousands of dollars simply because no one told them about them.
This post is part of the Money at Work series. It explains your paycheck and taxes in simple words, with easy math, so you can keep more of your money.
How to Understand Your Paycheck: Gross Pay vs. Net Pay
There are two numbers you need to know:
Gross pay: What you earned before anything was taken out.
Net pay: What you actually take home after taxes and deductions. This is sometimes called "take-home pay."
The difference between them is made up of taxes and deductions.
What Comes Out of Your Paycheck?
Here are the most common things you will see on a pay stub.
Taxes
Federal income tax: Money sent to the IRS based on your income and your W-4 form.
State income tax: Most states have one. A few states, like Texas and Florida, do not.
Local tax: Some cities and counties have their own income tax.
Social Security: 6.2% of your pay, up to a yearly limit.
Medicare: 1.45% of your pay.
Social Security and Medicare together are often called FICA, and they add up to 7.65%.
Pre-Tax Deductions
These come out before some or all taxes are figured, which lowers your taxes:
Health, dental, and vision insurance
HSA and FSA contributions
Traditional 401(k) or 403(b) retirement savings
Commuter benefits
After-Tax Deductions
These come out after taxes:
Roth retirement savings
Some life or disability insurance
Union dues
Wage garnishments, like child support or court-ordered payments
Let's Read a Pay Stub Together
Here is a made-up paycheck for someone paid every two weeks.
Gross pay: $1,600
Health insurance: −$60
401(k) (traditional): −$80
Federal income tax: −$110
Social Security and Medicare: −$118
State income tax: −$50
Now let's do the math: $1,600 − $60 − $80 − $110 − $118 − $50 = $1,182 take-home pay.
Why is Social Security and Medicare $118 and not $122? Because health insurance came out first, before those taxes. So FICA was figured on $1,600 − $60 = $1,540. And $1,540 × 7.65% = about $118.
Check Your Pay Stub for Mistakes
Payroll mistakes happen more often than people think. Every payday, check:
Your hours: Do they match what you worked, including overtime?
Your pay rate: Is it your current rate, including any raise?
Overtime and extra pay: Is overtime at time-and-a-half? Are shift differentials there?
Deductions: Are you being charged for benefits you did not sign up for, or the wrong amount?
PTO: Is your vacation and sick time being added and used correctly?
Year-to-date totals: These help you see the big picture.
If something looks wrong, contact payroll or HR right away. Keep your pay stubs, at least until you file your taxes for that year.
Your W-4: Big Refund or More in Your Paycheck?
When you start a job, you fill out a W-4 form. It tells your employer how much federal income tax to take out of each paycheck.
Many people love getting a big tax refund. But a big refund means you paid too much tax all year. It is like giving the government an interest-free loan.
Let's do the math. If you get a $2,400 refund and you are paid every two weeks:
$2,400 ÷ 26 paychecks = about $92 more per paycheck you could have had all year.
For someone living paycheck to paycheck, $92 every payday could pay for groceries, gas, or a bill.
On the other hand, if too little is taken out, you may owe money at tax time. The goal is to get close to even.
When to Update Your W-4
Update your W-4 when your life changes, such as:
Getting married or divorced
Having or adopting a baby
Starting a second job
A big raise or pay cut
Your spouse starting or stopping work
The IRS has a free Tax Withholding Estimator on IRS.gov that can help you figure out what to put on your W-4.
Two Jobs? Watch Your Withholding
If you work two jobs, or you and your spouse both work, you may not have enough tax taken out.
Each employer figures your taxes as if that job were your only income. When the two incomes are added together at tax time, you may owe money.
To help avoid a surprise bill, use the IRS Tax Withholding Estimator, or check the box on the W-4 for multiple jobs. Doing this once a year can save you from a big bill in April.
Your W-2 Explained
Each January, your employer sends you a W-2 form. It shows what you earned and what was taken out for the whole year. A few boxes to know:
Box 1: Your wages that are taxed for federal income tax. This may be less than your total pay because of pre-tax deductions, like health insurance and a traditional 401(k).
Box 2: The federal income tax taken out.
Boxes 3 and 5: Your wages for Social Security and Medicare.
Box 12: Codes for things like retirement savings and the cost of your health insurance.
Compare your W-2 with your last pay stub of the year. If something does not match, ask payroll before you file.
The Earned Income Tax Credit (EITC)
The Earned Income Tax Credit is one of the biggest tax breaks for working people with low to moderate income. It can lower the tax you owe, and you may get money back even if you owe no tax.
For tax year 2026, the largest EITC is $8,231 for families with three or more qualifying children.
Smaller credits are available for families with fewer children, and some workers with no children can qualify for a smaller amount.
Many people who qualify never claim it. If you work and your income is low or moderate, check whether you qualify. The IRS has a free EITC Assistant on its website.
Other Tax Credits and Breaks to Know
Child Tax Credit: A credit for families with qualifying children.
Child and Dependent Care Credit: Helps with child care costs so you can work.
The new overtime deduction: For 2025 through 2028, many workers can deduct part of their overtime pay.
The new tips deduction: For 2025 through 2028, many workers in jobs that get tips can deduct some of their qualified tips.
Standard deduction: For 2026, the standard deduction is $16,100 for single filers, $24,150 for heads of household, and $32,200 for married couples filing together. Most people take this instead of listing their deductions.
Saver's Credit and the New Saver's Match
If you have low to moderate income and save for retirement, the government may help you.
Saver's Credit: For retirement savings through 2026, you may get a tax credit for part of what you put into a retirement plan or IRA.
Saver's Match (starting in 2027): For 2027 contributions, the Saver's Credit is replaced by the Saver's Match. The government will put a match of 50% of the first $2,000 you save, up to $1,000, right into your retirement account.
For 2027, the match phases out and stops at income of $35,500 for single filers, $53,250 for heads of household, and $71,000 for married couples filing together. The match is bigger at lower incomes.
Let's do the math. If you qualify for the full match and save $2,000 for retirement in 2027:
$2,000 × 50% = $1,000 added to your account by the government
Total in your account: $2,000 + $1,000 = $3,000
Get Free Tax Help
You do not have to pay a lot to have your taxes done. Free help includes:
VITA (Volunteer Income Tax Assistance): Free tax help for people with low to moderate income, people with disabilities, and people who speak limited English.
TCE (Tax Counseling for the Elderly): Free help for people 60 and older.
IRS Free File: Free online tax software for many people.
MilTax: Free tax help for military members and their families.
Many free tax sites also help you find credits like the EITC.
Watch Out for Refund Loans and High Fees
Some tax preparers offer "refund advances" or charge high fees to get your money fast. Be careful. Ask about every fee before you sign anything. Free help is often available and can save you a lot.
What to Watch Out For
Keep your W-2. Your employer must send it by the end of January. You need it to file taxes.
Check your address with payroll. So your W-2 and other forms reach you.
Do not ignore IRS letters. Read them and respond on time. Scammers often pretend to be the IRS, so go to IRS.gov yourself instead of clicking links.
Save your pay stubs. They help you check your W-2 and spot mistakes.
Not Sure? Check With Your HR Department
If you have questions about your paycheck, deductions, or W-4, or about any benefit in the Money at Work series, check with your HR or payroll department. Ask them:
Can you explain each line on my pay stub?
Am I being charged the right amount for my benefits?
How do I update my W-4?
Where can I see my pay stubs and W-2 online?
Who do I contact if my paycheck looks wrong?
Small Steps to Keep More of Your Paycheck
Understanding your paycheck and taxes can feel overwhelming. The heart of Surviving Life Lessons is breaking big problems into small, manageable steps. Here are some SMART-style examples:
"On my next payday, I will check my hours, pay rate, and deductions line by line."
"This month, I will use the IRS Tax Withholding Estimator to check my W-4."
"Before tax season, I will look up whether I qualify for the Earned Income Tax Credit."
"This week, I will find a free VITA tax site near me."
"This month, I will start a folder for my pay stubs and tax papers."
If a step feels too big, make it smaller. If a time frame feels too short, give yourself more time.
Making These Steps Fit Your Life
Every paycheck and family is different. A single worker, a parent with kids, and someone with two jobs may all need different W-4 settings and may qualify for different credits. Look at your own life and choose the steps that fit right now. You can also learn from others. That is why we have free community groups, where people share what has helped them understand their money.
Frequently Asked Questions
What is the difference between gross pay and net pay?
Gross pay is what you earned before anything was taken out. Net pay is what you take home after taxes and deductions.
Why is my paycheck smaller than I expected?
Taxes, Social Security, Medicare, insurance, and retirement savings all come out before you get paid. Your pay stub shows each one.
Is a big tax refund a good thing?
A big refund means you paid too much tax during the year. You could have had that money in your paychecks instead. Many people adjust their W-4 to get closer to even.
What is the Earned Income Tax Credit?
It is a tax credit for working people with low to moderate income. For 2026, it can be worth up to $8,231 for families with three or more qualifying children.
What is the Saver's Match?
Starting with 2027 retirement savings, the Saver's Match can put up to $1,000 from the government into the retirement account of a worker with low to moderate income who saves.
Where can I get free help with my taxes?
VITA and TCE sites offer free tax help, and IRS Free File offers free online software for many people. Military families can use MilTax.
Why is my W-2 income lower than what I earned?
Pre-tax deductions, like health insurance, HSA or FSA money, and a traditional 401(k), lower the wages that are taxed. That is why Box 1 on your W-2 is often less than your total pay.
How long should I keep my pay stubs and tax papers?
Keep your pay stubs at least until you check them against your W-2 and file your taxes. The IRS generally suggests keeping tax records for at least three years after you file.
