Understanding Your First Paycheck

Your first paycheck can be smaller than the wage or salary in your offer. That often comes from deductions: federal income tax, Social Security tax, Medicare tax, state or local tax, and benefits you chose.

Who This Guide Is For#

Use this if you are starting a job, internship, campus job, training role, or salaried position and need to understand why your take-home pay is different from the amount in the offer.

This guide fits employees. If a company says you are an independent contractor, freelancer, or 1099 worker, your taxes and protections may work differently. Read W-2 Versus 1099 for a short comparison of employee and contractor pay.

What Payroll Needs Before You Start#

Most employers need a few items before they can pay you correctly:

Your employer may also ask for emergency contact information, state tax withholding forms, local tax forms, or benefit enrollment forms.

Paycheck Terms To Know#

The IRS says Form W-4 helps your employer withhold the correct federal income tax from your pay. The IRS also lists the 2026 employee rates for Social Security and Medicare taxes as 6.2% and 1.45%, with wage-base and additional Medicare rules that can change. Treat these rates as current reference points, not permanent numbers. Check the current IRS page if the rate matters for a decision.

W-4, I-9, And Direct Deposit Basics#

Form W-4#

Form W-4 tells your employer how to calculate federal income tax withholding. It does not decide your final yearly tax by itself. When you file a tax return, your actual tax is compared with what was withheld.

Common beginner mistakes:

• Choosing random entries because you want the form done fast.
• Copying another person's W-4.
• Assuming a refund means the form was "right."
• Forgetting to update the form after marriage, a second job, a child, or a major income change.

Use the IRS Form W-4 page and withholding estimator if you are unsure. Nonresident aliens may have special W-4 instructions, so international students and temporary workers should ask a qualified tax resource before guessing.

Form I-9#

Form I-9 is the employment eligibility verification form. You complete your part, and the employer checks documents that prove identity and authorization to work. The employer should not demand more or different documents than the I-9 process requires because of your citizenship, immigration status, accent, or country of origin.

Use the official USCIS Form I-9 page if you need the current form or acceptable document lists.

Direct Deposit#

Direct deposit sends your pay to a bank account. Payroll usually asks for:

• Bank name.
• Routing number.
• Account number.
• Account type, usually checking or savings.
• A direct deposit form, voided check, or bank letter if required.

How To Read Your First Pay Stub#

Use the pay stub to answer three questions: what period is covered, what you earned, and what came out.

1. Check your name, address, employee ID, and employer name.
2. Check the pay period and pay date.
3. Confirm hourly rate, salary amount, hours worked, overtime, bonus, commission, or stipend line.
4. Compare gross pay with the offer letter, timesheet, or work schedule.
5. Review taxes withheld: federal, state, local, Social Security, and Medicare.
6. Review benefit deductions, such as health insurance, dental, vision, retirement, transit, or union dues.
7. Confirm net pay matches the bank deposit or paper check.
8. Save the pay stub as a PDF or screenshot in a secure folder.

Common Mistakes#

Decision Rules#

Costs / Timing#

Payroll timing depends on the employer. Common pay schedules include weekly, every two weeks, twice a month, or monthly. The pay date may come several days after the pay period ends because payroll needs time to process hours, taxes, benefits, and bank transfers.

Your first payment may be delayed or different if:

• You started after the payroll cutoff.
• Direct deposit was not set up in time.
• Payroll needs an SSN, tax form, address, or bank correction.
• The employer pays the first check by paper check.
• A benefit deduction starts immediately.
• You worked only part of the pay period.

Keep a simple record of hours worked, schedule changes, tips, commissions, reimbursement promises, and payroll messages. Those records help if the first check is wrong.

What To Do Next#

1. Confirm your pay schedule and first pay date before you start.
2. Set up direct deposit only through the employer's official payroll process.
3. Complete Form W-4 carefully and ask a qualified tax resource if your situation is unusual.
4. Bring acceptable I-9 documents, not random extra documents.
5. Read your first pay stub before spending the money.
6. Save pay stubs and tax forms for future apartment, loan, tax, and immigration paperwork.
7. Ask payroll about errors in writing and keep copies.
