Federal tax withholding rules for supplemental wages including overtime pay for payroll compliance
Methodology: Overtime Pay = (Regular Hourly Rate × OT Multiplier) × OT Hours. Regular Pay = Regular Hourly Rate × Regular Hours. Total Weekly Pay = Regular Pay + Overtime Pay. Annual Estimate = Total Weekly Pay × Weeks Per Year. Overtime rate defaults to 1.5x (federal FLSA standard) with options for 2.0x (California double time) and custom rates.

How to Calculate Overtime Pay
Overtime pay is extra compensation earned when an employee works beyond their standard hours in a given workweek. Under the federal Fair Labor Standards Act (FLSA), most non-exempt hourly and salaried workers are entitled to overtime pay at 1.5 times their regular hourly rate for every hour worked over 40 in a single workweek. Understanding how overtime is calculated can help you verify your paycheck and plan your earnings.
Total Weekly Pay = (Regular Hours × Rate) + (OT Hours × OT Rate)
Example: 40 regular hours + 10 OT hours at $20/hr:
Regular pay = 40 × $20 = $800
OT pay = 10 × $30 = $300 Total = $1,100
Federal FLSA Overtime Rules
The FLSA sets the national floor for overtime pay. Key rules include: overtime is calculated on a per-workweek basis (not per pay period or averaged), a workweek is any fixed 7-consecutive-day period established by the employer, and overtime cannot be waived even if an employee agrees to straight-time pay for OT hours. Employers cannot average two weeks together to avoid paying overtime.
State Overtime Laws
Some states provide greater overtime protections than federal law. California is the most notable — it requires daily overtime (1.5x after 8 hours in one day), double time after 12 hours in a day, and double time for the 7th consecutive workday. Alaska and Nevada also have daily overtime thresholds. Always check your state’s labor laws in addition to federal FLSA rules, as the more favorable law applies to you.

Who Is Exempt from Overtime?
Not all workers qualify for FLSA overtime. Exempt employees include those in executive, administrative, and professional roles earning at least $684 per week ($35,568 per year) as of the current DOL threshold. Highly compensated employees earning over $107,432 annually may also be exempt. Certain industries like agriculture, transportation, and fishing have specific rules. If you’re unsure of your status, your HR department or the DOL’s wage and hour division can clarify.
💡 Pro Tip: If your employer misclassifies you as exempt to avoid paying overtime, you may be entitled to back pay for up to 2 years (or 3 years for willful violations). The DOL’s Wage and Hour Division handles overtime complaints at no cost to the employee.
Frequently Asked Questions
Under the FLSA, overtime pay is calculated at 1.5 times your regular hourly rate for all hours worked over 40 in a workweek. Formula: Overtime Pay = (Regular Hourly Rate x 1.5) x Overtime Hours. For example, at $20/hour working 10 overtime hours: OT Pay = $20 x 1.5 x 10 = $300.
Time and a half means your overtime rate is 1.5 times your regular hourly rate. If you earn $18/hour, your overtime rate is $18 x 1.5 = $27/hour. This rate applies to all hours worked beyond 40 in a single workweek under federal FLSA law.
Under federal law (FLSA), overtime kicks in after 40 hours worked in a single workweek. Some states have different rules — California requires overtime after 8 hours in a single day, and Alaska and Nevada also have daily overtime thresholds. Always check your state law in addition to federal rules.
To calculate weekly overtime pay: 1) Determine your regular hourly rate. 2) Multiply total regular hours (up to 40) by your regular rate. 3) Multiply overtime hours (above 40) by your rate times 1.5. 4) Add both amounts for total weekly pay. Example: 50 hours at $20/hr = (40 x $20) + (10 x $30) = $800 + $300 = $1,100.
Overtime pay is calculated before taxes. Your gross overtime pay is determined by the 1.5x formula, then all applicable taxes (federal income tax, state income tax, Social Security, Medicare) are withheld from the total gross pay including overtime. Overtime can push you into a higher tax bracket temporarily.
Most hourly workers are eligible for overtime under the FLSA. Salaried employees earning less than $684 per week ($35,568/year) are also generally entitled to overtime. Exemptions apply to executive, administrative, and professional employees earning above the salary threshold. Some industries like agriculture and transportation have different overtime rules.
For non-exempt salaried employees, calculate the regular rate by dividing weekly salary by hours worked. Then apply 1.5x to hours over 40. Example: $800/week salary, 50 hours worked. Regular rate = $800/50 = $16/hr. Overtime premium = $16 x 0.5 x 10 hours = $80 additional. Total pay = $800 + $80 = $880. This is called the fluctuating workweek method.
Double time is overtime paid at 2 times your regular hourly rate. It is not required by federal law but is required in certain states. California mandates double time for hours worked over 12 in a single day and for all hours on the 7th consecutive day of work in a workweek. Some union contracts and employer policies also provide double time.
Overtime pay is taxed as regular income, not at a special higher rate. However, because overtime increases your total gross income for the pay period, your employer may withhold more taxes using the supplemental wages method, which can make it appear that overtime is taxed more heavily. Your actual annual tax rate is based on total annual income.
When an employee works at two or more rates in a workweek, the regular rate for overtime is the weighted average. Add total earnings from all rates, divide by total hours worked to get the weighted regular rate, then calculate overtime at 0.5x that rate (since you already received straight-time pay for all hours). This is the blended rate overtime method required by the FLSA.
