Payroll documents fall into four groups: forms a new hire completes before the first paycheck, records the employer generates during employment, tax filings sent to federal and state agencies, and contractor paperwork. Every U.S. employer needs each group, and each has its own retention rule. Get the collection right on day one and the filings follow a predictable calendar; miss a form and the penalties compound quickly.
New Hire Forms Before the First Paycheck
Three federal documents belong in the file before wages are paid.
Form W-4 tells the employer how much federal income tax to withhold based on the worker’s filing status, dependents, and any additional adjustments.1Internal Revenue Service. About Form W-4, Employee’s Withholding Certificate The employee fills in legal name, Social Security number, home address, and withholding elections.2Internal Revenue Service. Form W-4 – Employee’s Withholding Certificate
Form I-9 verifies identity and authorization to work in the United States.3U.S. Citizenship and Immigration Services. I-9, Employment Eligibility Verification The employee completes Section 1 on or before the first day. The employer reviews acceptable identity and work-authorization documents within three business days of the hire date. Two mistakes account for most I-9 penalties: accepting photocopies instead of originals, and letting the three-day window slip.
A direct deposit authorization form captures bank routing and account numbers, usually paired with a voided check or bank verification letter. Many states also require their own withholding certificate for state and local income tax. Complete all of these before the first pay period runs and you avoid delayed paychecks and corrected filings.
New Hire Reporting to the State
Federal law requires every employer to report each new hire to a State Directory of New Hires. The report includes the employee’s name, address, Social Security number, and first date of paid services, plus the employer’s name, address, and federal employer identification number.4Office of the Law Revision Counsel. 42 USC 653a – State Directory of New Hires States set their own deadlines, but no state can require the report later than 20 days after hire. Employers reporting electronically may submit two monthly batches spaced 12 to 16 days apart.
Penalties are modest on paper: up to $25 per missed report, or up to $500 if the employer and employee conspired to avoid reporting.4Office of the Law Revision Counsel. 42 USC 653a – State Directory of New Hires They add up fast for a company onboarding dozens of workers at once.
Records Kept During Employment
Time and Hours
For every non-exempt employee, employers must record the time and day each workweek begins, hours worked each day, and total hours each workweek.5eCFR. 29 CFR Part 516 – Records to Be Kept by Employers Records must also show the regular hourly rate for any week in which overtime applies, total straight-time earnings, and total overtime premium pay.6U.S. Department of Labor. Fact Sheet 21 – Recordkeeping Requirements under the Fair Labor Standards Act No specific method is mandated. Paper timesheets, digital punch systems, and badge scanners are all fine, provided the records are complete and accurate.
For exempt employees, the burden is lighter. Keep the name, address, occupation, pay basis, and total compensation per pay period. Detailed daily hour tracking is not required.
Pay Stubs and Wage Statements
There is no federal law requiring pay stubs. The Fair Labor Standards Act requires employers to keep payroll records but not to hand employees a statement with each paycheck. Most states do require a wage statement in some form, with specifics that vary from mandatory delivery to availability on request. In practice, nearly every payroll system generates them automatically.
A typical pay stub shows gross wages and then each deduction: federal and state income tax withholding, Social Security tax (6.2% on wages up to $184,500 in 2026), Medicare tax (1.45% with no wage cap), health insurance premiums, retirement contributions, and any court-ordered garnishments.7Social Security Administration. Contribution and Benefit Base Net pay should be clearly distinguishable from gross.
Independent Contractor Paperwork
Contractor documentation is separate from employee payroll and equally important. Before making any payment, collect a completed Form W-9, which captures the contractor’s name, address, taxpayer identification number, and entity type.8Internal Revenue Service. Instructions for the Requester of Form W-9 Without a valid W-9, the business may be required to apply backup withholding to payments.
At year end, the business files Form 1099-NEC for each contractor who received at least the reporting threshold in nonemployee compensation during the calendar year.9Internal Revenue Service. Am I Required to File a Form 1099 or Other Information Return? For payments made on or after January 1, 2026, the One, Big, Beautiful Bill Act raised the threshold from $600 to $2,000. Starting in 2027, the threshold adjusts annually for inflation. Late-filing penalties for 1099-NECs match those for W-2s.
Payroll Tax Filings
Quarterly: Form 941
Form 941 is due every quarter and reports federal income tax withheld from wages plus both the employee and employer shares of Social Security and Medicare taxes.10Internal Revenue Service. About Form 941, Employer’s Quarterly Federal Tax Return For 2026, the Social Security rate is 6.2% each for employer and employee on wages up to $184,500, and Medicare is 1.45% each with no wage cap.11Internal Revenue Service. Instructions for Form 941 Most employers also deposit these taxes on a semiweekly or monthly schedule during the quarter, not only when the 941 itself is filed.
Annual: Form 940, W-2, W-3
Form 940 reports the employer’s federal unemployment tax (FUTA), calculated at 6.0% on the first $7,000 paid to each employee during the year.12Internal Revenue Service. Topic No. 759, Form 940 – Employers Annual Federal Unemployment (FUTA) Tax Return Most employers receive a credit of up to 5.4% for state unemployment taxes already paid, bringing the effective rate to 0.6% in most cases.
By January 31 of the following year, employers issue Form W-2 to each employee showing total wages, federal and state taxes withheld, Social Security and Medicare wages and taxes, and other compensation details for the prior calendar year.13Office of the Law Revision Counsel. 26 USC 6051 – Receipts for Employees Form W-3 is then filed with the Social Security Administration as a transmittal summarizing all W-2 data for that year.14Internal Revenue Service. About Form W-3, Transmittal of Wage and Tax Statements State unemployment and local income tax filings mirror these federal requirements, with forms and deadlines that vary by jurisdiction.
How Long to Keep Payroll Records
Federal retention rules overlap, so the safe approach is to follow the longest applicable period for each document type.
- Basic payroll records, three years. The Fair Labor Standards Act requires employers to preserve payroll records, including employee names, wages paid, and hours worked, for at least three years.6U.S. Department of Labor. Fact Sheet 21 – Recordkeeping Requirements under the Fair Labor Standards Act
- Supplementary wage records, two years. Time cards, wage rate tables, and work schedules must be kept for at least two years.6U.S. Department of Labor. Fact Sheet 21 – Recordkeeping Requirements under the Fair Labor Standards Act
- Employment tax records, four years. The IRS requires all employment tax records to be kept for at least four years after the tax becomes due or is paid, whichever is later. That covers W-2 copies, 941 filings, and records of wages, tips, and tax deposits.15Internal Revenue Service. How Long Should I Keep Records?
- Personnel records, one year. The EEOC requires personnel and employment records to be kept for one year from the date the record was made or the personnel action occurred, whichever is later. For involuntary terminations, records must be retained for one year from the termination date.16U.S. Equal Employment Opportunity Commission. Recordkeeping Requirements
Because the four-year IRS window is longest for most payroll paperwork, many businesses set a blanket four-year policy. Some extend it to six or seven years for state rules and extended audits. There is no penalty for keeping records longer than required, only for discarding them too early.
Electronic Storage
Neither the DOL nor the IRS requires paper originals. The FLSA sets no particular form for records, and employers may store them at the worksite or a central office as long as they remain complete, accurate, and available for DOL inspection.6U.S. Department of Labor. Fact Sheet 21 – Recordkeeping Requirements under the Fair Labor Standards Act
For IRS purposes, electronic records must meet Revenue Procedure 97-22. Every stored document must be legible and readable, and the system must include an indexing feature that cross-references source documents to the general ledger for a clear audit trail.17Internal Revenue Service. Revenue Procedure 97-22 During an examination, the employer must retrieve and reproduce any electronically stored record (including a paper printout if requested) and provide whatever hardware, software, or staff the agency needs. No license agreement can restrict IRS access.
Cloud-based payroll platforms meet these standards when you can export, search, and print on demand. The real risk with electronic storage is migration. When companies switch payroll providers, historical records sometimes get lost in transition. Before canceling any payroll service, export and independently archive every record you are required to retain.
Penalties for Missing or Late Payroll Documents
Late or missing W-2 and 1099-NEC filings carry tiered penalties that grow with the delay. For returns due in 2026, the penalty is $60 per form if filed within 30 days of the deadline, $130 if filed between 31 days late and August 1, and $340 if filed after August 1 or not filed at all. Intentional disregard doubles the maximum to $680 per form.18Internal Revenue Service. Information Return Penalties For a 50-employee company, filing W-2s two months late means $6,500 in penalties before anyone reviews the tax data.
Form I-9 violations run separately. Civil fines for paperwork violations, meaning failing to properly complete, retain, or make the form available, currently range from $288 to $2,861 per form. Because the fine is per employee, exposure scales quickly for a company that neglected I-9s across its workforce.
FLSA recordkeeping failures work differently. Rather than a fine per missing document, the DOL may use the absence of records as grounds to accept an employee’s account of unpaid wages during an investigation. When the employer cannot produce timesheets or pay records, proving the employee’s version wrong becomes the employer’s problem. That is where most wage-and-hour claims turn expensive: not from an assessed penalty, but from an employer who could not disprove the claim.
