The $500,000 Tripwire: When Federal Wage and Overtime Law Starts Covering Your Business

In fiscal year 2025, the U.S. Department of Labor's Wage and Hour Division recovered more than $259 million in back wages for nearly 177,000 workers — an average of about $1,465 per worker. Many of those dollars came out of the pockets of small business owners who had no idea federal wage law applied to them at all. Their most common defense? "We're too small for that law."

If your business just crossed $500,000 in annual sales, that defense probably expired without anyone notifying you. There is no letter, no registration, no certificate. One day you are outside the Fair Labor Standards Act's enterprise coverage; the next day every nonexempt employee you have is covered by federal minimum wage, overtime, recordkeeping, and child-labor rules — and you owe up to two years of back pay (three if the violation is willful) plus an equal amount in liquidated damages if you get it wrong.

Here is how the tripwire works, the second tripwire almost nobody knows about, and the compliance checklist to run the moment you cross it.

There Is No Employee-Count Threshold in the FLSA​

Most federal employment laws have a headcount trigger you can count on one hand: the Family and Medical Leave Act generally applies at 50 employees, the Affordable Care Act's employer mandate at 50 full-time equivalents, Title VII at 15. Owners naturally assume wage law works the same way.

It does not. The Fair Labor Standards Act has no minimum employee count. A three-person shop can be fully covered, and a thirty-person shop can (rarely) fall outside enterprise coverage. Coverage depends on what the business does and how much business it does — not how many people it employs. There are two independent routes to coverage, and either one is enough.

Route 1: Enterprise Coverage and the $500,000 Test​

An enterprise is covered if it meets both of these conditions:

1. It has employees engaged in commerce or in the production of goods for commerce, or employees handling, selling, or otherwise working on goods or materials that have been moved in or produced for commerce by any person.
2. It has at least $500,000 in annual gross volume of sales made or business done.

In practice, condition 1 is satisfied by almost every business in America. Goods or materials that "have been moved in" commerce include everyday items: the cleaning supplies shipped from another state, the point-of-sale hardware, the coffee beans, the packaging. If your team handles anything that crossed a state line at any point, condition 1 is met — and condition 2, the dollar threshold, becomes the only question that matters.

What counts toward the $500,000​

The key word is gross. This is not profit, not net income, not "what the business cleared." It is the total annual dollar volume of sales made or business done — essentially your top line. A restaurant doing $520,000 in food sales with $8,000 in net profit is over the threshold. A retailer with $600,000 in revenue and a loss for the year is over the threshold.

For most small businesses, the practical test is simple: look at last year's gross receipts. If the number starts with a 5 followed by five more digits, or anything larger, enterprise coverage applies. Track it the same way you track revenue for estimated taxes — because this is one more number where your books determine your legal obligations.

Who is covered with no dollar threshold at all​

Certain enterprises are covered regardless of their dollar volume:

• Hospitals and institutions primarily engaged in the care of the sick, aged, mentally ill, or people with disabilities who reside on the premises
• Schools — preschools, elementary and secondary schools, and institutions of higher education
• Federal, state, and local government agencies

Run a small private preschool, a home-health agency with live-in clients, or a tutoring center? The $500,000 test never enters the picture. You are covered from dollar one.

Route 2: Individual Coverage — The Tripwire Nobody Sees​

Here is the part that surprises owners of businesses well under $500,000: even if the enterprise is not covered, individual employees can be covered on their own. Any employee who personally engages in interstate commerce — or in producing goods for interstate commerce — is covered by the FLSA as an individual.

The Department of Labor interprets "engaged in interstate commerce" broadly. Covered activities include:

• Processing credit card transactions (the authorization travels across state lines)
• Taking or placing interstate phone calls, emails, or orders
• Shipping, receiving, or transporting goods across state lines
• Ordering supplies or inventory from out-of-state vendors
• Handling or transmitting paperwork, payments, or data that moves between states

Think about a typical five-person business under $400,000 in sales: the cashier runs customer credit cards through a processor, the owner orders inventory from a distributor two states away, the assistant books freight from an out-of-state carrier. Under the Labor Department's longstanding interpretation, those employees are individually covered — which means the minimum wage, overtime, and recordkeeping rules apply to them even though the business flunks the $500,000 enterprise test.

The honest takeaway: if your business accepts cards, orders anything from out of state, or ships anything anywhere, assume at least some of your workforce is individually covered, and run payroll as if the FLSA applies. The corner case where truly nobody is covered — a purely local, cash-only business using only in-state inputs — is vanishingly rare in a card-and-internet economy.

What Coverage Actually Requires of You​

Crossing into coverage changes five obligations at once:

1. Federal minimum wage​

Covered nonexempt employees must be paid at least $7.25 per hour. That is the federal floor; your state's minimum is often higher, and the higher number always wins. Coverage means you must satisfy both and pay whichever is greater.

2. Overtime at time-and-a-half​

Nonexempt employees must receive overtime pay at one-and-a-half times their regular rate for all hours worked over 40 in a workweek. Three points owners get wrong constantly:

• The workweek is a fixed, recurring 168-hour period. You cannot average two light weeks against one heavy week.
• Private-sector employers generally cannot offer compensatory time off instead of overtime pay. Comp time in lieu of overtime is largely a public-sector device.
• Paying someone a salary does not make them exempt. Exempt status requires passing a duties test (executive, administrative, professional, outside sales, or computer-employee duties) and the salary-basis and salary-level tests. Job titles decide nothing.

3. Child-labor restrictions​

The FLSA limits the hours and types of work for employees under 18 — particularly ages 14 and 15, who face strict caps on daily hours, weekly hours, and permissible times of day, plus a list of prohibited hazardous occupations for all minors. Summer hiring season is when small businesses most often trip over these rules.

4. Recordkeeping​

Covered employers must keep payroll records for at least three years — including employee identifying information, hours worked each day and week, wages paid, and deductions — and must preserve records on which wage computations are based (time cards, wage-rate tables, work schedules) for at least two years. These records must be available for inspection by Wage and Hour Division representatives. Poor timekeeping is not just sloppy; in a dispute, courts can credit employees' reasonable recollections of their hours over an employer's missing records.

5. The workplace poster​

Every covered employer must display the official FLSA poster explaining the Act in a conspicuous place. It is free from the Department of Labor, and failing to post it is its own violation.

The Mistakes That Cost Real Money​

"We're under $500,000, so we're exempt"​

As shown above, individual coverage usually fills the gap. Treat the $500,000 line as the point where everyone is covered via the enterprise — not the point where coverage begins.

Confusing revenue with profit​

Owners who "only made $60,000 last year" on $700,000 in sales are covered. The threshold measures what customers paid you, not what you kept.

Misclassifying workers as independent contractors​

Coverage questions and classification questions stack: a business can owe back wages to people it never considered employees at all. The Labor Department's worker-classification rulemaking has seesawed in recent years, but enforcement attention on misclassification has not. If someone works your schedule, on your premises, with your tools, get classification advice before treating them as a contractor.

Averaging hours across pay periods​

Overtime is weekly. A 50-hour week followed by a 30-hour week still contains 10 overtime hours, even though the two-week average is 40. Semi-monthly payroll does not change the 7-day workweek math.

Assuming state law is the same​

Many states set higher minimum wages, daily-overtime rules, stricter meal-and-rest-break requirements, and lower or no enterprise thresholds. Federal coverage is the floor. Always check your state's wage-and-hour rules on top — when they differ, the standard more protective of the employee controls.

Crossing $500,000? Run This Checklist​

If your trailing-twelve-month gross volume is approaching or has passed the threshold, work through these steps now rather than after an investigator calls:

1. Confirm the math. Pull gross sales or gross business done for the last four completed quarters from your books — not your tax return's net figures. Calendar the check quarterly going forward.
2. Audit every role's exempt status. List each position, its actual duties, and how it is paid. Salary alone exempts no one; verify the duties and salary tests for anyone treated as exempt.
3. Fix timekeeping before you need it. Move hourly workers to a real time-tracking system that records start, stop, and meal periods daily. Reconstructing hours from memory during an investigation is how small discrepancies become big liabilities.
4. Recompute overtime correctly. Verify the regular rate includes nondiscretionary bonuses and shift differentials, and that the multiplier applies past 40 hours in each single workweek.
5. Post the poster and keep the records. Display the federal poster, confirm state posters are current, and verify payroll records go back three years and wage-computation records two.
6. Check state law. Minimum wage, overtime thresholds, final-pay timing, and child-labor rules may all be stricter where you operate.
7. Mind retaliation rules. The FLSA prohibits retaliating against employees for asking about pay, filing a complaint, or cooperating with investigators — and retaliation claims can succeed even when the underlying wage claim does not.

What Noncompliance Costs​

The price structure is designed to make violations more expensive than compliance:

• Back wages for two years prior to the claim — three years if the violation is willful.
• Liquidated damages in an equal amount — effectively doubling the back-pay bill — unless the employer proves good faith.
• Attorney's fees and court costs on top, in employee lawsuits.
• Civil penalties per violation, higher for willful or repeated violations, plus separate child-labor penalties.
• Criminal exposure for willful violations, and personal liability for owners and officers involved in pay decisions — the company form does not reliably shield individuals here.

Against that, the cost of a timekeeping system, an hour of employment-counsel review, and a payroll audit is trivial.

Keep Your Payroll Records Audit-Ready From Day One​

Notice how many of these obligations come back to the same foundation: complete, contemporaneous records of hours, rates, and payments. Businesses that track every hour and every dollar as a matter of habit sail through wage-and-hour questions; businesses that reconstruct them afterward pay for the privilege.

That is fundamentally a bookkeeping discipline. Whether you cross the $500,000 threshold this year or three years from now, maintaining clean payroll and time records in a system you control means the coverage question is an administrative checkbox, not a forensic excavation.
