Understanding US Overtime Rules: FLSA Exempt vs Non-Exempt
The Fair Labor Standards Act (FLSA) is the federal law that sets minimum wage, overtime pay, and record-keeping rules for US businesses. At the center of FLSA compliance is a single, critical decision: classifying each of your employees as either exempt or non-exempt. That classification determines whether they're owed overtime pay.
Get this wrong, and you're looking at back pay, liquidated damages, attorney's fees, and a regulatory headache. Get it right, and you've got a clear, defensible framework for paying your team fairly — and protecting yourself.
This guide explains how.
Why Exempt vs. Non-Exempt Matters
Here's the fundamental rule: non-exempt employees get overtime pay. Exempt employees don't.
Under the FLSA, any non-exempt employee who works over 40 hours in a week must be paid 1.5 times their regular hourly rate for the extra hours. Exempt employees receive a fixed salary, regardless of how many hours they work. No overtime, period — no matter if they work 45 hours or 60.
The critical part: the default is non-exempt. Every employee is presumed to be owed overtime unless they meet specific, strict criteria for an exemption. The burden of proof is entirely on you — the employer. You cannot assume an employee is exempt just because they have a "manager" title or work on salary.
And here's why this matters so much: misclassification is one of the most expensive employment law mistakes a business can make. If you're paying someone a salary and assuming they're exempt when the FLSA says they should be non-exempt, you owe back overtime for every week they were misclassified. That can be years of unpaid wages plus liquidated damages — often doubling what you actually owe.
The good news: the rules are clear. You just have to apply them carefully.
The Three Tests for Exempt Status
To classify an employee as exempt, they must pass all three of these tests. Fail even one, and they're non-exempt.
1. Salary basis test
The employee must be paid a fixed, predetermined salary that doesn't fluctuate based on how much work they do or how well they do it.
The key word is "predetermined." The salary must be paid in full for any week in which the employee performs any work (with narrow exceptions). If you dock their pay because a project wrapped early or because you think they didn't produce enough, you've just violated the salary basis test — and made them non-exempt.
Deductions that break the rule: Partial-day absences for personal reasons, partial-day sick leave, or docking for poor quality work.
Deductions that are fine: Full-day absences for personal reasons, full-day sickness or injury (if you have a bona fide sick-leave plan), disciplinary suspensions of a full day or more, or absences for unpaid leave like FMLA.
(If this feels oddly specific, remember: the rule exists to prevent employers from punishing salaried workers for minor time off. The spirit is that exempt employees get a stable paycheck, not an hourly calculation disguised as a salary.)
2. Salary level test
The employee must earn at least the minimum salary threshold set by the Department of Labor. This threshold changes periodically — sometimes substantially — so you need to check the current DOL overtime rules before classifying anyone.
As of 2026, this threshold has increased multiple times in recent years and will likely continue adjusting. (The salary floor keeps rising because DOL wants the exemption to mean something — not to become a workaround for avoiding overtime pay.)
One exception: Highly compensated employees earning well above a much higher annual threshold can sometimes qualify for exemption under a relaxed duties test — but they still need to actually do some exempt work.
3. Duties test
The employee's primary duty must fit one of the recognized exemptions. Primary duty means the most important responsibility or the one that takes the most time.
This is where most misclassifications happen — because "duties" is genuinely nuanced and context-dependent.
The Five Main Exemption Categories
Executive exemption
Who qualifies: The employee's primary duty is managing the business or a department. They customarily and regularly direct at least two full-time employees (or equivalent). They have actual authority to hire, fire, or promote — or their recommendations on hiring and firing carry real weight.
Common roles: Department managers, store managers, team leads with genuine supervisory power.
Common misclassification: An employee with "manager" in their title who still does 70% of the same work as their team. If your "manager" is spending most of their time doing individual-contributor work and only a fraction managing, they're not exempt. Title is irrelevant. Actual duties are everything.
Administrative exemption
Who qualifies: The primary duty is office or non-manual work directly connected to managing the business or its operations (or the customers' operations). The role requires regular exercise of discretion and independent judgment on matters of real significance.
Key phrase: "directly connected to management or general operations." This includes finance, accounting, budgeting, quality control, purchasing, marketing, compliance, legal, HR, and similar functions. It does NOT include production work, service delivery, or routine operational tasks.
Common roles: HR managers, finance professionals, marketing managers, compliance officers, executive assistants with serious decision-making power.
Common misclassification: A receptionist or administrative assistant filing paperwork, scheduling meetings, and answering phones. Routine clerical work doesn't meet the "discretion and independent judgment" requirement, even if the job title says "office coordinator."
Professional exemption
Two types:
Learned professionals: Primary duty requires advanced knowledge in a specialized field — science, engineering, law, medicine, teaching, architecture. The knowledge is intellectual, not just technical skill or routine application of established methods.
Creative professionals: Primary duty is invention, imagination, originality, or talent in a recognized artistic field.
Common roles: Doctors, lawyers, engineers, architects, teachers, scientists, writers, graphic designers.
Common misclassification: A technician who applies established procedures, or a para-professional who assists professionals. Just because the work requires formal education doesn't mean it's exempt.
Computer employee exemption
Employees in certain tech roles may be exempt if their primary duties include systems analysis, software development, testing, modification of programs or operating systems, or a mix of these.
This exemption also has both a salary threshold and an alternative hourly rate threshold.
Common misclassification: Help desk technicians, IT support staff, and hardware repair people. Troubleshooting tickets and maintaining equipment are not the same as systems analysis or software development.
Outside sales exemption
Who qualifies: Primary duty is making sales or obtaining orders or contracts. The employee customarily and regularly works away from your office or place of business.
Unique feature: This exemption has no salary threshold. A commissioned salesperson can be exempt at any pay level.
Common misclassification: Inside sales reps or customer service reps who take orders by phone, email, or video. They're not "outside" salespeople, so the exemption doesn't apply — even if they're 100% commission-based.
Classifying Your Team: A Four-Step Process
Step 1: List every distinct position
Don't list individual people. List the job roles. "Customer service representative," "junior accountant," "warehouse lead," "part-time bookkeeper."
Step 2: Check salary and basis
Is the person paid a fixed salary on a salary basis? (Not hourly, not bonuses, not fluctuating.) If the answer is no, stop. They are non-exempt, regardless of duties.
Step 3: Analyze actual, day-to-day duties
Read the job description, but then set it aside. Duties testing is based on reality, not documentation.
Observe what the person actually does. What is the primary duty — the most important responsibility or the one taking the most time? Does it genuinely fit one of the five exemption categories above?
Be honest. If someone's job title is "manager" but they spend 70% of their time doing the same work as their team, that's not an executive exemption. Duties are what matter, not titles.
Step 4: Document your reasoning
For every position you classify as exempt, write down:
- Which exemption applies (executive, administrative, professional, etc.)
- How the duties test is satisfied (what primary duties fit the exemption)
- The salary amount and the date of classification
This documentation is your evidence if the classification is ever audited or challenged.
Record Keeping and Overtime Pitfalls
What you must track for non-exempt employees
The FLSA requires you to maintain accurate records:
- Hours worked each day and total hours per week
- How wages are paid (hourly, salary, piece rate, etc.)
- Straight-time earnings each day and week
- Overtime compensation each week
- Total wages paid each period and payment dates
An integrated timesheet and payroll system ensures hours are captured accurately, overtime is calculated correctly, and payroll reflects actual time worked — reducing disputes, compliance risk, and your exposure to back-pay claims. (Spreadsheets and manual entry are where overtime calculations go wrong.)
For exempt employees, detailed hour records aren't required by federal law — though many employers track hours for project management, client billing, or workload analysis.
Four mistakes that create real liability
1. Automatic lunch deductions: If non-exempt employees are required to stay on-call or available during lunch, that time is compensable and must be paid. Automatically deducting 30 minutes without confirming they actually took an uninterrupted break is a classic path to unpaid overtime liability.
2. Off-the-clock work: An email checked at 10 p.m., work done before clocking in, a Slack message answered during a break — if a non-exempt employee is working, it counts. If you know or reasonably should know they're working off the clock, the time must be recorded and paid.
3. Averaging hours across weeks: The FLSA calculates overtime week by week, not across a pay period. If an employee works 50 hours one week and 30 hours the next, they're owed 10 hours of overtime for week one — even though the biweekly average is 40. You cannot average it out.
4. Ignoring state law: Many states have overtime rules stricter than the federal FLSA. Some require daily overtime (over 8 hours in a single day), some have lower salary thresholds for exemption, some mandate additional protections. You must comply with both federal and state law — whichever is more favorable to the employee. Check your state's wage-and-hour rules and consider US state-by-state minimum wage requirements as part of your overall compliance picture. If you have employees in multiple states, you might need different classifications for the same role depending on where they work.
Frequently Asked Questions
Q: Can an employee choose to be classified as exempt? A: No. Classification is not negotiable or optional. It's a legal determination based on the FLSA criteria. An employee cannot waive their right to overtime by agreement, even if both of you want to.
Q: What if I pay someone a salary but they work 50 or 60 hours a week? A: Salary doesn't automatically equal exempt. They must pass all three tests: salary basis, salary level, and duties. If they don't, they're non-exempt and legally owed overtime for all hours over 40 each week.
Q: Can I make someone exempt by putting it in their job offer or employee handbook? A: No. The classification is determined by law, not by documentation. If the job doesn't actually meet the exemption criteria, the employee is non-exempt regardless of what the offer letter or handbook says.
Q: How often should I review classifications? A: At a minimum, whenever a job changes significantly (different responsibilities, management duties added or removed, new skill requirements). Also review whenever the DOL raises the salary threshold — if a salary that was exempt-compliant last year is now below the threshold, you need to reclassify.
Q: What do I do if I discover I've been misclassifying someone? A: Correct it immediately. Reclassify them as non-exempt, implement time tracking going forward, calculate back overtime owed based on hours actually worked (to the best of your records), and consult an employment attorney about your liability and remediation options. Prompt, good-faith correction can reduce penalties significantly.
Q: Does "manager" in their title mean they're exempt? A: Absolutely not. Title is completely irrelevant. If someone has "manager" in their title but spends 70% of their time doing the same work as their team, they don't meet the executive duties test. Actual duties determine exemption, not the business card.
Q: Are all commissioned salespeople exempt? A: Only if they meet the outside sales exemption — meaning they're making sales and regularly working away from your office. Inside sales reps who take orders by phone, email, or video are not outside salespeople, so the exemption doesn't apply — even if they're 100% commission-based.
The Bottom Line
Exempt vs. non-exempt classification is a legal determination, not a title or a salary convention. The FLSA doesn't care what you call the role, how much you're paying, or what you've documented in your handbook. It cares about three things: Is the salary fixed and above the threshold? And do the actual, day-to-day duties fit one of the five recognized exemptions?
When in doubt, classify as non-exempt. The cost of paying overtime when due is always less than the cost of defending a wage-and-hour claim years later.
If you're managing payroll manually or across disconnected spreadsheets, it's easy to lose track of classifications, forget to record all hours worked, and mess up overtime calculations. An integrated time-tracking and payroll system cuts that risk dramatically. Accurate federal and state payroll tax compliance starts with accurate timekeeping and overtime calculation — two areas where most small-business owners feel the pinch.
Start with a clear, documented classification for every role on your team. Then set up automated timesheet tracking so the overtime calculations happen without error. That combination — clear decisions plus reliable systems — is what separates compliant payroll from a lawsuit waiting to happen.
