Payroll records fall into a few categories, and each has different retention requirements. Missing documentation during an audit or employee dispute creates problems that are entirely avoidable with basic record-keeping.

Employee information documents include W-4 forms for federal withholding elections, state withholding forms, I-9 employment eligibility verification, direct deposit authorizations, and benefit enrollment forms. These establish who you employed and the terms under which you paid them.

Time and attendance records cover timesheets or time clock records, leave requests, and overtime calculations. If an employee ever disputes hours worked or overtime pay, these records are your only defense.

Payment records include payroll registers showing gross pay, deductions, and net pay for each period. Keep pay stubs or earnings statements and records of how employees were paid, whether by check or direct deposit.

Tax documents require the most careful attention. Keep copies of every W-2 you issue, quarterly 941 returns, annual 940 returns, and all state unemployment and withholding filings. These prove you withheld and remitted taxes correctly.

The IRS requires employment tax records for at least four years after the tax is due or paid. The Department of Labor requires three years for most payroll records. I-9 forms follow their own rule: keep them three years from date of hire or one year after termination, whichever is later.

The practical answer is to keep everything for seven years. Storage is cheap and audits can reach back further when problems are suspected. Working with virtual bookkeepers in New Mexico who understand these requirements helps ensure nothing falls through the cracks.

Digital records work for most payroll documents. Scan paper records and organize by employee and year. Original signed documents like W-4s and I-9s should be preserved, but digital copies of pay stubs and reports are acceptable.

Proper payroll system setup makes record retention automatic. Good payroll software stores everything digitally and organizes it in a way that makes retrieval straightforward when you need it. The goal is having documentation available without thinking about it, not scrambling to reconstruct records years later.
