Payroll Recordkeeping: A Technical Guide to Retention Compliance

Core Retention Standards for U.S. Employers

Payroll recordkeeping is governed by three primary federal bodies: the Internal Revenue Service (IRS), the Department of Labor (DOL) under the Fair Labor Standards Act (FLSA), and the Equal Employment Opportunity Commission (EEOC). Failure to maintain these records can result in significant penalties during audits or wage-and-hour litigation.

The 4-Year IRS Rule

The IRS requires that all records regarding employment taxes be kept for at least four years after the tax becomes due or is paid, whichever is later. This includes:

• Employer Identification Number (EIN).
• Amounts and dates of all wage, annuity, and pension payments.
• Amounts of tips reported.
• The fair market value of in-kind payments.
• Names, addresses, social security numbers, and occupations of employees and recipients.
• Dates of employment.
• Periods for which employees were paid while absent due to sickness or injury and the amount and weekly rate of payments.
• Copies of employees' income tax withholding certificates (Forms W-4, W-4P, W-4S, and W-4V).

The 3-Year FLSA and EEOC Rule

The DOL and EEOC require employers to keep basic payroll records for three years. This mandate covers data used to compute pay, including:

• Total hours worked each workday and each workweek.
• Total daily or weekly straight-time earnings.
• Total overtime pay for the workweek.
• All additions to or deductions from wages.
• Total wages paid each pay period.
• Date of payment and the pay period covered by the payment.

The 2-Year Supplemental Rule

Under the FLSA, you must keep records on which wage computations are based for two years. This includes time cards, piece work tickets, wage rate tables, and records of additions to or deductions from wages. This also applies to records explaining why you may pay different wages to employees of opposite sexes in the same establishment (e.g., seniority systems or merit systems).

State-Specific Variations

While federal law sets a baseline, several states require longer retention periods. For example, California and New York have statutes of limitations for wage claims that effectively necessitate keeping records for six years. Always default to the longest applicable retention period to mitigate legal risk.

Digital Storage Requirements

The IRS and DOL permit electronic recordkeeping provided the system ensures the integrity, accuracy, and accessibility of the data. The system must be able to produce legible hard copies upon request and must include a retrieval system that allows for easy indexing and searching of specific records.
