FLSA Overtime Rules Explained: A Complete 2026 Guide

The Fair Labor Standards Act (FLSA) is the 1938 federal law that establishes the overtime rule most American workers live under. It requires employers to pay non-exempt employees at least 1.5 times their regular rate of pay for every hour worked over 40 in a single workweek. Misunderstanding or misapplying this rule costs workers an estimated $15 billion in unpaid overtime each year.

Who the FLSA covers

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

Employees are either non-exempt (entitled to overtime) or exempt (not entitled to it). 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 under the FLSA is calculated per workweek — a fixed, recurring period of seven consecutive days. Hours cannot be averaged across pay periods. If a biweekly pay period contains 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 offset it.

Four states — California, Alaska, Nevada, and Colorado — layer daily overtime rules on top of the federal weekly rule. California is the strictest: overtime triggers after 8 hours in a day (not just 40 in a week) and double time kicks in after 12. The overtime calculator applies whichever state rule applies to your situation.

The regular rate: the correct overtime base

Overtime is 1.5× the regular rate of pay, which is not simply the hourly wage. The regular rate is total cash compensation for the week (wages, nondiscretionary bonuses, commissions, shift differentials) divided by total hours worked. An employer who pays time-and-a-half on the base wage while ignoring a production bonus is underpaying overtime. The overtime calculator handles blended-rate scenarios automatically.

Exemptions: the three-part test

The most widely used exemption is the 'white-collar' exemption covering 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/week ($35,568/year) — the 2026 federal threshold, reinstated after the 2024 rule that would have raised it was vacated. Third, the employee's actual primary job duties must satisfy the relevant duties test — the executive, administrative, or professional requirements.

A title does not make an exemption. A 'store manager' who spends 90% of their time stocking shelves alongside hourly employees, with no real authority to hire or fire, does not meet the executive exemption regardless of their job title or the salary they earn. When in doubt, the burden is on the employer to prove the exemption applies.

Other exemptions

The FLSA also exempts outside sales employees, computer professionals earning above $27.63/hour or $684/week on a salary, highly compensated employees earning over $107,432 annually (with at least some exempt duties), and certain agricultural workers. Partial exemptions exist for police, firefighters, and hospital workers under specific overtime calculation methods. These are narrow and fact-specific — employers cannot self-certify an exemption without applying the correct legal test.

Penalties for violations

When the WHD finds a violation, it orders back wages for up to two years (three for willful) and equal liquidated damages, doubling the payout. Civil money penalties reach $2,411 per violation in 2026 for repeat or willful violators. Private lawsuits under § 216(b) allow employees to sue individually or as a collective, and the employer pays attorney fees if the plaintiff wins — making FLSA cases economically viable even for modest claims.
