Fair Labor Standards Act (FLSA): The Complete Employer’s Guide for Small Businesses

The Fair Labor Standards Act is the federal law that most directly affects how you pay your employees. It sets the floor for wages, determines who gets overtime, dictates what records you must keep, and restricts when minors can work. Every employer with employees is affected by it. And yet, the Department of Labor estimates that a significant percentage of employers are not in full compliance.

The reason is not that employers want to break the law. It is that the FLSA is deceptively complex. It covers five major areas, each with its own rules, exceptions, and state-level interactions. The exempt versus nonexempt classification alone has generated more employment litigation than almost any other area of HR law. And for small business owners without an HR department, navigating it without a guide is a recipe for expensive mistakes.

This guide covers what the FLSA requires of employers, how to determine whether your employees are exempt or nonexempt, what records you must keep and for how long, what the penalties are for violations, and how FLSA compliance connects to the onboarding workflow. I built FirstHR to manage the employee profiles, document storage, and onboarding paperwork that FLSA recordkeeping demands, but this guide is about understanding the rules so you can comply with confidence.

What Is the Fair Labor Standards Act (FLSA)?

The Fair Labor Standards Act is a federal law enacted in 1938 that establishes minimum wage, overtime pay, recordkeeping, and child labor standards for employees in the private sector and in federal, state, and local governments. It is administered and enforced by the Wage and Hour Division of the U.S. Department of Labor.

Three things the FLSA does not do that employers commonly assume it does: it does not define full-time or part-time employment (that is left to the employer), it does not require breaks or meal periods (some states do), and it does not limit the number of hours an adult employee can work in a week (it only requires overtime pay after 40 hours).

When the FLSA Was Passed and Why It Exists

President Roosevelt signed the Fair Labor Standards Act on June 25, 1938 (Public Law 75-718, 52 Stat. 1060), and it took effect that October 24. It was the last major piece of New Deal legislation, written after a decade in which federal wage floors and hour caps had been struck down in the courts or left entirely to the states.

The original Act set a minimum wage of 25 cents an hour, capped the workweek at 44 hours before overtime was owed (stepping down to 40 hours by October 1940), and set 16 as the general minimum age for employment. Everything since has been amendments to those same four levers: the wage floor, the hour threshold, who is exempt, and what minors may do.

That history explains the shape of the law you comply with today. The FLSA is old, narrow, and specific. It says nothing about paid leave, health benefits, scheduling notice, or remote work, because none of that was in scope in 1938 and Congress never added it. Those obligations come from the states instead, which is why the state layer matters as much as the federal one.

Who Is Covered by the FLSA

The FLSA covers employers through two types of coverage: enterprise coverage and individual coverage. If either applies, the employer must comply with the FLSA for covered employees.

The 5 Core Provisions of the FLSA

The FLSA governs five areas of employment. Each creates specific obligations for employers, and each carries penalties for noncompliance. Understanding all five is essential because violations in one area often trigger investigations across all five.

The five provisions interact. An employer who miscalculates overtime (provision 2) will also have incorrect records (provision 3), which means a DOL audit finds two violations instead of one. An employer who employs a 15-year-old for 25 hours during a school week (provision 4) has also failed to maintain proper records of the minor's hours (provision 3).

Minimum Wage: Federal vs State vs Local

The federal FLSA minimum wage is $7.25 per hour, unchanged since July 24, 2009. However, more than 30 states and dozens of cities have set higher minimum wages. The rule is simple: the employer must pay whichever minimum wage is highest among federal, state, and local rates.

For small businesses operating in a single state, the practical action is straightforward: look up your state minimum wage, compare it to $7.25, and pay the higher rate. For multi-state employers, each employee must be paid at least the minimum wage of the state (and city) where they work. The DOL state minimum wage page maintains the current rate for every state.

One qualification on the local rate: in much of the country, cities and counties are not allowed to set one. Many states have passed preemption statutes that void local wage ordinances outright, so the "check your city" step ends before it begins. Iowa is the clearest example: HF 295, signed March 30, 2017, voided the five county minimum wage ordinances then in effect and reverted those workers to $7.25, and it barred local leave, scheduling, and benefit mandates in the same stroke. Before you build payroll around a city rate, confirm your state permits the city to set one at all.

Overtime Pay: The 40-Hour Rule

The FLSA requires employers to pay nonexempt employees at least 1.5 times their regular rate of pay for every hour worked beyond 40 in a single workweek. This is the provision that generates the most litigation and the most expensive mistakes.

The DOL Fact Sheet #17A provides the complete overtime rules including the regular rate calculation. The DOL overtime hub covers additional resources including exemption guidance and compliance assistance. A few states add additional overtime requirements: California requires overtime after 8 hours in a single day (not just 40 in a week), Alaska requires daily overtime after 8 hours for employers with 4+ employees, and Colorado requires overtime after 12 hours in a day. Part-time classification does not change any of this: a part-time employee who works 45 hours in a week still earns 5 hours of overtime.

How to Calculate FLSA Overtime

FLSA overtime is calculated on the regular rate, which is total straight-time pay for the workweek divided by total hours worked in that week. It is not the base hourly wage whenever the employee also receives a non-discretionary bonus, a shift differential, or a commission. The Wage and Hour Division sets out what goes into the rate and what may be excluded in Fact Sheet 56A.

Take a nonexempt employee paid $20 an hour who works 46 hours in one workweek and earns a $200 production bonus tied to output. The bonus is non-discretionary, so it enters the regular rate, and the overtime owed changes with it.

Two rules the arithmetic depends on. Each workweek stands alone, so hours are never averaged across a two-week pay period. And a bonus that covers several weeks is allocated back across those weeks, with the overtime recomputed for each of them rather than settled in the week the bonus is paid.

If you pay any bonus, commission, or shift differential to a nonexempt employee, the arithmetic above has to happen week by week rather than once a pay period. The column-by-column version of that calculation, with a worksheet to run it on, is in the guide to overtime pay.

Exempt vs Nonexempt: The Classification That Matters Most

Every employee covered by the FLSA must be classified as either exempt or nonexempt. This classification determines whether the employee is entitled to overtime pay. Getting it wrong is the single most common and most expensive FLSA violation.

The 3-Part Exemption Test

To classify an employee as exempt from overtime, the employer must demonstrate that the employee meets all three parts of the exemption test. If any one part is not met, the employee is nonexempt and entitled to overtime.

The salary level threshold is the most frequently litigated element because it changes (or almost changes) periodically. The current threshold of $684/week has been in effect since January 1, 2020. The DOL's 2024 attempt to raise it to $1,128/week was vacated by the Eastern District of Texas in November 2024. Employers should monitor DOL rulemaking because future increases are likely.

Where the Federal Overtime Rule Stands Now

The threshold is $684 per week, and the attempt to raise it is formally over. The Department of Labor published a final rule on May 15, 2026 that strikes the vacated 2024 text out of the regulations and restores 29 CFR Part 541 to the version that existed before it, which is the version employers have been operating under since the courts vacated the rule.

The practical version for a small business: nothing changed in what you owe. The salary level stays at $684 per week, the highly compensated threshold stays at $107,432 a year, and the duties tests are untouched. If you raised salaries to stay ahead of the announced $1,128 threshold, those raises were never required, and clawing them back now buys a morale problem that costs more than the payroll it saves.

What this should change is how you read overtime news. A salary threshold moves through notice-and-comment rulemaking and then through litigation, so an announced number is not an obligation until it survives both. Watch for a published final rule with an effective date, then check whether your state sets a higher threshold, because several do and those numbers move on their own schedule.

The 5 White-Collar Exemption Categories

The duties test (part 3 of the exemption test) requires the employee's primary duty to fall into one of five white-collar categories. Each category has a specific duties test with distinct requirements.

Whatever you conclude for a given position, write the conclusion down while the reasoning is fresh. In an audit or a lawsuit, an exemption you can explain in a dated one-page record is a very different position from an exemption you have to reconstruct from memory three years later. Use one record per position, not per person.

Misclassification: The Most Expensive FLSA Mistake

Misclassification occurs when an employer classifies a nonexempt employee as exempt, thereby failing to pay required overtime. This is the most common and most costly FLSA violation for small businesses.

The financial exposure is significant because FLSA damages are doubled by default. If an employee is owed $10,000 in back overtime, the employer pays $10,000 in back wages plus $10,000 in liquidated damages (unless the employer can prove the violation was in good faith and based on reasonable grounds), plus the employee's attorney fees. For a small business with 3 misclassified employees over 2 years, the total exposure can easily reach $50,000 to $150,000.

FLSA Recordkeeping: What You Must Keep and for How Long

The FLSA requires employers to maintain specific records for every employee. These records must be accurate, complete, and available for inspection by the Wage and Hour Division. The DOL Fact Sheet #21 details every required data element.

The recordkeeping obligation is non-negotiable and non-delegable. Even if a third-party payroll provider processes your payroll, the employer is responsible for ensuring the records exist and are accurate. During a DOL audit, the investigator will request these records. If they do not exist or are incomplete, the investigator assumes the violation occurred and calculates damages based on the employee's account of hours worked.

At FirstHR, employee profiles store the identification data elements (name, address, DOB, occupation, classification) and document management retains signed acknowledgments and policy documents with timestamped audit trails. This does not replace payroll records (you need a payroll system for wage and hour data), but it covers the employment-record side of the FLSA requirement.

Child Labor Standards

The FLSA restricts the hours and types of work that employees under 18 can perform. These rules apply to all covered employers, including small businesses. The DOL child labor page provides the full list of prohibited occupations and hour restrictions.

Child labor violations carry the highest per-violation penalties in the FLSA: up to $15,138 per violation, and up to $68,801 if the violation causes death or serious injury to a minor. For small businesses in retail, food service, and agriculture that commonly employ minors, strict compliance with hour restrictions and prohibited-occupation rules is essential. Your onboarding checklist should include age verification and hour-restriction documentation for any employee under 18.

FLSA Compliance During Onboarding: The Overlooked Obligation

Most employers do not realize that onboarding activities are compensable work time under the FLSA. If the activity is mandatory, controlled by the employer, performed during the employer's normal working hours, and primarily for the employer's benefit, the employee must be paid for that time.

The practical implication: if your onboarding process takes 4 hours on Day 1 and you start paying the employee from hour 5, you owe 4 hours of back pay. If your onboarding includes a mandatory online training module that takes 2 hours to complete before the start date, those 2 hours are compensable. For nonexempt employees, this time also counts toward the 40-hour weekly overtime threshold.

State Wage and Hour Laws: Where They Override the FLSA

The FLSA sets the federal floor. Many states have wage and hour laws that exceed federal requirements. When state law is more generous to the employee than the FLSA, the state law applies. When the FLSA is more generous, the FLSA applies. The employer must comply with whichever standard benefits the employee more.

For multi-state employers, each employee must be paid under the rules of the state (and city) where they work. A company headquartered in Texas (no state overtime beyond FLSA, no paid sick leave, $7.25 minimum wage) with a remote employee in California must comply with California's daily overtime, $16.50 minimum wage, paid sick leave, and meal/rest break requirements for that California employee.

Penalties for FLSA Violations

The liquidated damages provision is what makes FLSA violations particularly expensive: the default is that the employer pays double the back wages owed. The employer can avoid liquidated damages only by proving that the violation was in good faith and that the employer had reasonable grounds for believing the act or omission was not a violation. This is a high bar. For most small businesses, the practical exposure is back wages x 2 plus attorney fees. The retaliation guide covers the anti-retaliation provisions that protect employees who file wage complaints.

The FLSA Statute of Limitations

The FLSA statute of limitations is two years from the date each underpaid paycheck was due, extended to three years where the violation was willful. Willful means the employer knew the conduct violated the Act or acted with reckless disregard for whether it did, which is why an ignored complaint or a warning you filed away is often what turns a two-year case into a three-year one.

The clock runs paycheck by paycheck rather than from the original decision. A misclassification made five years ago is still live: every payday since sits inside its own window, and the exposure keeps rolling forward for as long as the classification stands. Filing a lawsuit also stops the clock only for the people named in it, since each additional employee in a collective action keeps accruing until their written consent to join is filed.

FLSA Audits and DOL Investigations

An FLSA audit is a Wage and Hour Division investigation of your pay practices, and many begin with a single confidential employee complaint rather than anything visible from the outside. The Division also runs directed investigations aimed at industries with a history of violations, which is how restaurants, construction, home care, and staffing companies get visited without any complaint at all.

The investigator does not have to tell you why they came, and the visit does not have to be announced. Section 11(a) of the Act gives Department of Labor representatives authority to enter the premises, inspect records, and question employees privately. The Division's Fact Sheet 44 describes the sequence: the investigator presents credentials and explains the process, examines the records that establish which laws apply, examines payroll and time records, interviews employees in private, then holds a final conference covering what was found and how to correct it.

There is no published timetable, so how long a Department of Labor investigation takes has no single answer. A narrow single-location case with clean records can close in a few weeks. One that expands across several years, multiple locations, or a contested classification routinely runs a year or more. The variable you control is records: complete payroll and time records shorten every stage, and their absence lets the investigator rely on the employees' account of the hours they worked.

Running Your Own Audit First

The cheapest FLSA audit is the one you run before anyone else does, using the same evidence an investigator would request. Pull every salaried classification and test it against the three-part test in writing. Recalculate overtime for any week a nonexempt employee received a bonus, a commission, or a shift differential. Confirm the records exist for the full retention period and that someone can actually read them.

Then fix what you find and date the correction. A violation you identified and corrected yourself, with a record of when and why, is the good-faith evidence that argues against liquidated damages. A violation an investigator finds first carries the doubling by default. The checklist below is the working version of that self-audit.

Steps 3 through 5 get much easier with a system that captures hours automatically, and the time clock rules for hourly employees spell out exactly what that system has to record.

FLSA vs FMLA: They Sound Similar but Are Completely Different

The FLSA and FMLA are the two most commonly confused federal employment laws, largely because their acronyms differ by only one letter. They govern entirely different aspects of employment.

The two laws intersect in one important area: hours worked under the FLSA determine FMLA eligibility. An employee must have worked 1,250 hours in the preceding 12 months to be eligible for FMLA leave. The FLSA defines what counts as "hours worked."
