Timesheet Retention: Use a U.S. Schedule Starting at 4 Years

Federal law requires you to keep timesheets used for wage calculations for at least 2 years, and basic payroll records for at least 3 years. The IRS wants employment tax records for at least 4 years. Our practical advice: keep timesheets at least 4 years, or follow the longest rule that applies to you, and longer where your state or industry demands it.

TL;DR:

• The FLSA separates basic payroll records, retained for 3 years, from supporting wage calculations such as timecards, retained for 2 years.
• Records supporting certain payroll tax credits may need 6 years, while OSHA injury logs require 5 years and medical or exposure records last employment plus 30 years.
• State rules can extend federal periods, with New York requiring at least 6 years for certain payroll records; employers should verify each state annually.
• Electronic timesheets are acceptable when they remain accessible, legible, retrievable, and reproducible, with audit trails, exports, backups, and retrieval tests supporting inspection readiness.
• A discrimination charge or lawsuit suspends routine deletion of relevant records until final disposition, so employers should disable automated deletion and notify record owners.

What does the FLSA require you to keep, and for how long?

The Fair Labor Standards Act splits records into two buckets, and mixing them up is the most common mistake we see. Basic payroll records, the ones showing total wages paid, must be preserved for at least 3 years. Supporting wage-calculation records, such as time cards, timesheets, work schedules and wage rate tables, must be kept for at least 2 years, as the Department of Labor’s Fact Sheet #21 lays out. The federal regulation on preserving records draws the same line between basic records and supplementary ones.

In practice, a payroll register showing each employee’s gross pay belongs in the 3-year bucket. The daily start and stop times behind that pay, plus any hourly timecards, belong in the 2-year bucket. Think of the first as the answer and the second as the work shown.

Those records also have to be ready when someone asks. The Department of Labor can inspect them, and your files must be available and transcribable on request. The agency’s recordkeeping guidance treats this as a burden-of-proof issue: if you cannot produce records during an investigation, that can create a presumption of non-compliance and expose you to penalties.

How do IRS rules affect how long you keep timesheets?

Tax rules often outlast wage rules. The IRS says to keep employment tax records for at least 4 years after the tax becomes due or is paid, whichever is later, as its guidance on how long to keep records explains. Its page on employment tax recordkeeping restates that baseline.

What does the IRS expect to see? Payroll tax filings such as Forms 941, records of wages paid and taxes withheld, dates of employment, and documentation behind any credits you claimed. Timesheets matter here because they substantiate the wages those filings report.

One detail trips up many small employers. The same IRS guidance notes that records supporting certain payroll tax credits, including some COVID-related credits, may need to be kept for at least 6 years. If you claimed one, your timesheets and payroll files need to stay available for that longer window. Because the IRS limit is longer than the 2-year FLSA minimum for timesheets, deleting them at the 2-year mark can leave your tax filings without support.

Which OSHA and specialized records need even longer retention?

Safety and medical records run on much longer clocks than timesheets. OSHA requires employers to retain the injury and illness log (OSHA 300) and incident reports (OSHA 301) for 5 years following the end of the calendar year they cover. Employee medical and exposure records must be preserved for the duration of employment plus 30 years.

OSHA’s retention and updating rule adds a wrinkle: you may need to update stored logs during the retention period if a newly discovered recordable injury or a classification change comes to light.

Other regimes can stretch retention further. FMLA regulations require specified payroll and identifying employee data to be kept for no less than 3 years, and records kept in computer form must be transcribable or copyable. Other rules may affect how long you need to keep records, so check which requirements apply to your organization.

The fix is an inventory. List every record type you hold, note each rule that touches it, and schedule it for the longest applicable period.

Why do state laws change your retention period?

Federal minimums are a floor, not a ceiling. States can require longer retention, and when they do, the longer rule governs. California commonly requires 3 years for certain hours-and-wage records, and New York requires at least 6 years for certain payroll records. Both exceed the 2-year federal timesheet minimum, and the Department of Labor’s Fact Sheet #21 points employers to state requirements for exactly this reason.

If you employ people in more than one state, you may be subject to several different periods at once. A restaurant group with locations in two states can’t assume one location’s rule covers the other.

Verifying your state takes four steps:

1. Open your state labor department’s recordkeeping page and note the stated period for hours and wage records.
2. Compare it to the federal periods and write down the longer one.
3. Add that period to your written retention schedule.
4. Record the source and the date you checked it, so you can show your work later.

Recheck once a year, since state rules change.

What retention schedule can you adopt today?

When rules overlap, follow the longest one that applies to the record. Here is the schedule we recommend as a safe starting point for most U.S. small employers, before you layer on state rules:

Why 4 years for timesheets when the federal floor is 2? Because the same hours feed your tax filings, and aligning timesheet retention with the 4-year IRS window means you never hold a payroll record whose supporting hours are already gone.

Tag each record with its retention period and a start date when it is created. Schedule archiving or deletion only after the window closes, plus a modest buffer, so a late audit request or an overlooked state rule does not catch you empty-handed. Our own guide to timesheet retention requirements walks through the 2- and 3-year distinction in more depth.

How should you store and manage digital timesheets?

Paper is not required. The Department of Labor confirms there is no legal requirement to keep timesheets on paper, as long as the records stay accessible, legible and retrievable for inspection. The EEOC takes the same view: its informal guidance confirms electronic records can satisfy the rules if the system captures and retains everything in the original documents and allows reproduction. The EEOC’s recordkeeping page adds that the real risk is not the format but being unable to substantiate an action when challenged.

A defensible digital setup includes:

• Timestamps and an audit trail showing who changed what, and when
• Payroll-ready exports you can generate on demand
• Secure backups stored separately from the primary system
• Role-based access controls and encryption
• Retention flags on each record
• Scheduled retrieval tests to prove you can actually pull old data

Our write-up on a timesheet audit trail covers how these pieces fit together.

For a workable routine, export records to an archive on a fixed schedule, keep versioned backups, and tag everything so it is searchable by employee and date range. Privacy matters too: some teams prefer tools that process sensitive data locally, as in this on-device privacy approach from a partner that builds private, on-device apps.

Pro Tip: Once a year, ask your system for one random employee’s timesheets from three years ago. If it takes more than a few minutes, fix your archive before an auditor asks.

When must you stop deleting records?

Your normal schedule pauses the moment legal trouble appears. If an employee files a charge of discrimination or a lawsuit, you must preserve all relevant records until final disposition, regardless of when they would otherwise expire. The EEOC’s summary of recordkeeping obligations states this plainly.

Put a legal hold into practice with four actions:

• Document the hold in writing, with the date and the matter it covers.
• Notify everyone who controls relevant records, including payroll, HR and IT.
• Suspend automated deletion in every system that touches those records.
• Centralize copies so counsel can review them.

Destroying records early, even by routine auto-delete, can look like spoliation and bring penalties. Involve legal counsel as soon as a charge arrives, and keep the hold in place until counsel releases it in writing.

How do you write a timesheet retention policy?

A good policy is short enough that people read it. Cover these components: scope, record categories, retention periods, preservation triggers, storage and access rules, the disposal process, who is responsible, and how often you review it.

Then work this checklist:

1. Map every place timesheets and payroll records live.
2. Assign an owner for each record type.
3. Configure your systems with retention tags and dates.
4. Run a retrieval test on old records.
5. Train the staff who handle payroll and HR.
6. Schedule an annual review.
7. Document the sources behind each retention period.

For a sample sentence to adapt in your handbook: “We retain employee timesheets and related payroll records for at least four years, or longer where federal, state or industry rules require, and we suspend deletion whenever a charge, audit or lawsuit is pending.” Our guide to audit-ready timesheets lists the three records small businesses most need on hand.

What mistakes do employers make most often?

The error I see most is treating the 2-year federal minimum as the target. It is a floor, and it leaves tax filings and state rules unsupported. The second is relying on a system nobody has tested, so records exist but cannot be produced quickly.

A time tracking system with exportable records and a clear audit trail may help reduce administrative work and make records easier to produce. Keeping overtime and break calculations with the relevant records may also help when someone questions a paycheck.

FAQ

How long should a company keep timesheets?

Federal law sets a floor of 2 years for timesheets used to calculate wages. We recommend at least 4 years so they line up with the IRS’s 4-year employment tax window. Follow your state’s rule if it is longer.

What is the 7 year retention policy?

It is a common company policy rather than a federal timesheet requirement. Some employers adopt a 7-year window as a conservative buffer that covers most tax and state rules. Check your state’s requirements before choosing it.

What are the federal record retention requirements for employers?

Payroll records must be kept for at least 3 years and timesheets for at least 2 years under the FLSA. Employment tax records need 4 years, and OSHA injury logs need 5 years. Medical and exposure records run for employment plus 30 years.

Can I keep timesheets electronically instead of on paper?

Yes. The Department of Labor says there is no requirement to keep paper timesheets, provided electronic records stay accessible, legible and retrievable for inspection. A system that can export clean records on request meets that test.
