Overtime & Paycheck Guides
Whether you are an hourly worker checking a weekly paycheck, a salaried employee unsure if you qualify for overtime, or a taxpayer confused by withholding spikes or W-2 Box 12 Code TT, these reference guides clarify how overtime works under statutory labor law. Across each guide, we explore the federal 40-hour rule, state daily overtime and double-time standards, executive and administrative exemption tests, payroll tax withholding mechanics, and the new 2025–2028 federal overtime deduction. Every guide breaks down the governing labor regulations in plain English and links onward to a dedicated calculator that runs the exact mathematical formulas for your paycheck.
Federal rules
Under the Fair Labor Standards Act (FLSA), covered non-exempt employees must receive overtime compensation at 1.5 times their regular rate for all physical hours worked beyond 40 in a designated workweek. The regular rate is not simply base hourly pay—it must factor in non-discretionary bonuses and shift differentials divided across actual hours worked, while excluding non-working hours like PTO and holidays. Master the statutory math and common payroll errors before reviewing your check.

State spotlight
California maintains some of the nation's most stringent wage protections under California Labor Code § 510. Non-exempt workers earn 1.5× overtime for hours exceeding 8 in a workday and double time (2.0×) after 12 daily hours, plus additional premiums on a 7th consecutive workday. Strict anti-pyramiding statutes dictate how daily and weekly hours interact without double-counting the same premium hours.

Who qualifies
Earning an annual salary does not automatically make an employee exempt from overtime pay under federal labor regulations. To be lawfully classified as exempt, an employee must satisfy the salary-basis test, clear the federal salary-level floor of $684 per week ($35,568 per year), and perform specific executive, administrative, or professional job duties. Learn how to verify your job classification and calculate overtime if you are a non-exempt salaried worker.
Paycheck & tax
When overtime hours cause a paycheck to jump, payroll withholding tables annualize that single pay period as if you earned that amount all year, often withholding taxes at a temporarily higher bracket. However, progressive tax brackets ensure you always take home more total pay, with your true tax liability reconciling at year-end between your marginal and effective tax rates. Under the 2025–2028 OBBBA rules, qualifying workers can deduct the 0.5× overtime premium up to $12,500 for single filers or $25,000 for married joint filers using Form W-2 Box 12 Code TT on Schedule 1-A.
