New Hire Payroll Forms Checklist: What to Complete Before Your First Paycheck

Starting a new job should not require decoding every payroll acronym on your first day. Still, the forms you complete during onboarding affect how much tax is withheld, whether your employer can verify work authorization, where your pay is sent, and how quickly payroll can fix an error.

This guide is for U.S. employees who want to understand what they are being asked to sign before the first paycheck. It is also useful for small employers and HR teams who need a plain-language checklist to share with new hires. It is not tax or legal advice; when a form affects your specific tax situation, immigration status, or wage rights, follow the official instructions and your employer’s verified process.

Quick answer: the core new-hire payroll forms

Most employees will see some combination of these forms:

Form or request	What it does	Who normally receives it
Form W-4	Tells payroll how much federal income tax to withhold from wages.	Your employer or payroll provider.
Form I-9	Verifies identity and authorization to work in the United States.	Your employer keeps it on file; do not send it to Payroll Form Hub.
Direct deposit authorization	Gives payroll the bank, routing, and account details needed to send wages electronically.	Your employer, HR portal, or payroll provider.
State withholding form	Tells payroll how to withhold state income tax when your state uses a separate form.	Your employer or payroll provider.
Local tax forms	Covers city, county, school district, or other local wage taxes where applicable.	Your employer or payroll provider.
Benefits and deduction elections	Authorizes deductions for health coverage, retirement, commuter benefits, union dues, or other voluntary items.	HR, benefits administrator, or payroll provider.

If you only remember one rule, remember this: forms with your Social Security number, bank account, routing number, immigration document number, or identity documents should be submitted only through a trusted employer or official agency workflow.

Form W-4: federal income tax withholding

Form W-4 is the form employees use so their employer can withhold federal income tax from pay. The IRS says employees should consider completing a new W-4 each year and when personal or financial circumstances change, such as marriage, a second job, a new dependent, or a major change in deductions.

For a new hire, the practical goal is not to predict your exact refund. It is to avoid obvious withholding mismatches. Before you submit a W-4, gather:

Your filing status.
Whether you work more than one job or have a spouse who works.
Dependents and other credits you expect to claim.
Other income not subject to withholding, if relevant.
Deductions beyond the standard deduction, if you plan to itemize.
Any additional amount you want withheld each pay period.

The IRS Tax Withholding Estimator can help when your situation is more complex. It is especially useful if you have multiple jobs, a spouse with wages, significant self-employment income, or a prior-year balance due.

Common W-4 mistakes include using an old saved copy without checking the current revision, leaving Step 2 blank when multiple jobs are involved, adding extra withholding without understanding the per-paycheck effect, and treating a W-4 as a one-time task. Payroll can apply only the form you provide; it cannot infer your household tax picture.

Form I-9: employment eligibility verification

Form I-9 is different from a tax form. It is used to verify a new employee’s identity and employment authorization. USCIS states that employers must complete and retain Form I-9 for employees hired for employment in the United States, and I-9 Central explains the employee and employer sections in detail.

For employees, the most important timing rule is simple: Section 1 is completed by the employee no later than the first day of employment for pay. The employer or authorized representative completes Section 2 after reviewing acceptable documents, generally within three business days of the hire date.

As of May 26, 2026, USCIS lists Form I-9 with edition date 01/20/25, and also describes validity rules for certain 08/01/23 editions. Because I-9 editions and expiration dates can change, check the USCIS page before relying on a downloaded copy.

Practical I-9 checks:

Use the current USCIS form or the employer’s approved electronic I-9 system.
Review the acceptable documents list before your first day.
Bring original, unexpired documents unless the official instructions allow an alternative.
Do not provide more documents than required; employees choose which acceptable document combination to present.
Do not mail Form I-9 to USCIS or ICE; employers retain it according to the I-9 rules.

If you are completing an electronic I-9 remotely, confirm the link came from your employer or payroll provider. A real I-9 process may ask for sensitive identity information, which is exactly why the channel matters.

Direct deposit: bank details and pay delivery

A direct deposit form or portal authorization tells payroll where to send your wages. Unlike Form W-4 or Form I-9, there is no single federal direct deposit form that every employer uses. Your employer may provide a PDF, a payroll platform screen, or a benefits/payroll onboarding workflow.

Before entering bank details, verify:

The routing number.
The account number, which is not always the number printed on a debit card.
Whether the account is checking, savings, payroll card, or prepaid card.
Whether you want the full paycheck in one account or split across multiple accounts.
Whether your employer requires a voided check, bank letter, or account verification step.

For prepaid cards, the Consumer Financial Protection Bureau notes that direct deposit usually requires the prepaid account number and the card provider’s routing number, and that the account number may not be the same as the card number. That distinction matters: entering a card number where an account number is required can delay pay.

Security tip: treat direct deposit setup like online banking. Do not submit bank information through a generic file upload, email attachment, text message, or link you cannot verify. If someone asks you to “confirm payroll” outside the employer’s normal channel, pause and contact HR through a known phone number or company system.

State and local withholding forms

Federal withholding is only part of payroll. Many employees also need a state withholding form, and some locations require local tax forms. The exact requirement depends on where you work, where you live, and how your employer handles multi-state payroll.

Examples of questions to ask:

Does my state use its own withholding certificate, or does it rely on federal W-4 data?
If I live in one state and work in another, does my employer need forms for both?
Does my city, county, or school district have a local wage tax?
Does remote work change the forms I need to complete?
Does the employer’s payroll provider supply the state form automatically?

State rules change more often than employees expect. Use your state revenue or tax department site as the final source, and check the year printed on any PDF. Payroll Form Hub can help you locate and understand forms, but the official state agency and your employer’s instructions control what you should submit.

What to finish before your first paycheck

Use this sequence if you want a clean payroll start:

Accept the job offer and confirm the official onboarding channel.
Complete Form I-9 Section 1 by your first day of work for pay.
Bring or upload I-9 acceptable documents only through the employer-approved process.
Complete Form W-4 after reviewing household jobs, dependents, and extra withholding.
Complete state and local withholding forms if your work or residence location requires them.
Set up direct deposit and double-check routing/account numbers.
Review benefit and deduction elections before the payroll cutoff.
Save confirmation receipts or screenshots that do not expose full SSN or bank details.
Check your first pay stub for legal name, address, tax withholding, deductions, hours, rate, and net pay.

The first pay stub is your best early warning system. If federal withholding is zero when you expected withholding, if the state is missing, if a deduction appears twice, or if direct deposit went to only one account when you requested a split, report it quickly. Payroll errors are usually easier to correct before several pay periods have passed.

What not to submit to random websites

Payroll forms often contain high-value identity and financial data. A helpful website should explain forms, link to official sources, and help you prepare questions. It should not ask you to upload sensitive new-hire paperwork unless it is actually your employer, payroll provider, benefits administrator, bank, or an official government agency.

Be careful with:

Full Social Security numbers.
Bank routing and account numbers.
Passport, green card, employment authorization, or I-94 details.
Driver’s license images.
Dates of birth combined with legal name and address.
Completed W-4, I-9, or state withholding PDFs.

If you are unsure, ask HR where to submit the form. A short verification step is much better than sending payroll data to the wrong place.

Employee vs. contractor: why the form set changes

This checklist is for employees. Independent contractors usually do not complete Form W-4 or Form I-9 for the company paying them. Contractors are commonly asked for Form W-9 and are often paid through accounts payable rather than payroll.

If a company calls you a contractor but controls your schedule, tools, training, and day-to-day work like an employee, the form mismatch may be a signal to ask questions. Worker classification affects taxes, wage rights, benefits, and reporting. Do not solve that question by guessing which form looks familiar; ask the company for clarification and consult official guidance when needed.

A simple rule for every payroll form

Every new-hire payroll form should answer four questions:

What is this form for?
Who is collecting it?
Which official source or employer policy supports it?
What sensitive information does it contain?

If you can answer those four questions, onboarding becomes much less stressful. You do not need to become a payroll expert before your first day. You just need to know which forms affect tax withholding, which forms prove work authorization, which forms route your pay, and which details deserve extra care before you press submit.
