FLSA Overtime Rules Explained: A Complete 2026 Guide

The Fair Labor Standards Act (FLSA) is the 1938 federal law that sets the overtime rule most American workers live under. It requires employers to pay non-exempt employees at least 1.5 times their regular rate for every hour worked over 40 in a single workweek.

Misunderstanding or misapplying this one rule costs workers an estimated $15 billion in unpaid overtime each year. The mechanics are not complicated once you break them down, and knowing them is how you tell whether your own paycheck is right.

Who the FLSA covers

The FLSA applies to employers engaged in interstate commerce or with gross revenues above $500,000 a year, which in practice covers nearly every private business. Individual employees are also separately covered if their work touches interstate commerce, and using a phone, processing credit cards, or handling goods that crossed state lines all qualify under broad court interpretation.

Every employee is either non-exempt, meaning entitled to overtime, or exempt, meaning not. The exemption is the exception, not the rule. Most workers are non-exempt, including nearly all hourly workers and many salaried ones.

The 40-hour workweek rule

Overtime is calculated per workweek, a fixed and recurring period of seven consecutive days. Hours cannot be averaged across pay periods. If a biweekly pay period has one 50-hour week and one 30-hour week, overtime is owed for the 10 hours over 40 in the first week; the quiet second week does not cancel it out.

Paid time off and holidays you did not actually work do not count toward the 40. The threshold is hours worked, not hours paid. For a hands-on walkthrough, see how to calculate overtime pay.

The regular rate: the correct overtime base

Overtime is 1.5x the regular rate, which is not simply your hourly wage. The regular rate is your total cash compensation for the week, including wages, nondiscretionary bonuses, commissions, and shift differentials, divided by total hours worked.

An employer who pays time and a half on the base wage but ignores a production bonus is underpaying overtime. Example: $20 an hour plus a $200 weekly bonus over 50 hours yields a regular rate of $24, so overtime should be $36 an hour, not $30. The overtime calculator handles these blended-rate cases automatically.

Exemptions: the three-part test

The most common exemption is the white-collar exemption for executive, administrative, and professional employees. Three conditions must all be met. First, the employee must be paid a fixed salary, the salary-basis test. Second, that salary must be at least $684 a week, or $35,568 a year, the current federal threshold. Third, the actual primary job duties must satisfy the relevant duties test.

A title does not create an exemption. A store manager who spends 90% of their time stocking shelves alongside hourly staff, with no real power to hire or fire, does not meet the executive exemption no matter what the business card says. The burden is on the employer to prove the exemption applies. The exempt salary calculator checks the salary side for you.

Other exemptions to know

The FLSA also exempts outside sales employees, computer professionals earning above $27.63 an hour or $684 a week on salary, and highly compensated employees earning over $107,432 a year who perform at least some exempt duties. Narrow partial exemptions exist for police, firefighters, and hospital workers under specific calculation methods.

These are fact-specific and easy to get wrong, which is exactly why misclassification is so common. If you are salaried and unsure, exempt vs non-exempt employees breaks the categories down further.

State rules can go further

The FLSA is a floor. Several states layer daily overtime or higher salary thresholds on top. California requires overtime after 8 hours in a day and double time after 12, and sets a much higher exempt salary floor than federal law.

Alaska, Nevada, and Colorado also have daily overtime in some form. If you work in one of those states, applying only the federal rules can badly undercount what you are owed. The full breakdown is in overtime rules by state.

What violations cost employers

When the WHD finds a violation, it orders back wages for up to two years, three for willful, plus equal liquidated damages, doubling the payout. Civil money penalties reach $2,451 per violation in 2026 for repeat or willful violators.

Private lawsuits under 216(b) let employees sue individually or as a collective, and the employer pays the attorney fees if the worker wins. That fee-shifting is what makes FLSA cases economically viable even for modest claims, and you can read more in how to file a Department of Labor complaint.

Frequently asked questions

Does a salary mean I never get overtime? No. A salary alone does not make you exempt. You must also clear the salary threshold and meet the duties test. Many salaried workers are non-exempt and owed overtime.

Can my employer offer time off instead of overtime pay? In the private sector, no. Comp time in place of cash overtime is illegal for private employers, though public agencies can use it under strict limits. See comp time vs overtime.

Does overtime apply to weekends and holidays automatically? Not by itself. The FLSA only requires overtime for hours over 40 in a week. Weekend or holiday premiums are a matter of employer policy unless those hours push you past 40.

Check your own overtime

The FLSA is only useful to you once you apply it to your real hours and rate. That is where a vague suspicion turns into a number you can act on.

Run a week through the overtime calculator, and if you are salaried, confirm your status with the exempt salary calculator. This is general information, not legal advice, but it is the fastest way to see whether your paycheck follows the law.
