How do overtime pay and the overtime deduction fit together?
They answer different questions. Federal law requires at least 1.5 times your regular rate for every hour over 40 in a workweek, so at $20 an hour a 50-hour week pays $1,100. The time and a half calculator handles that paycheck math, including double time.
The no tax on overtime calculator works on your tax return instead. For tax years 2025 through 2028, you may deduct the premium part of qualified overtime, such as the extra half of time and a half, from federal taxable income. The no tax on tips calculator does the same for qualified tips. Both deductions lower federal income tax only. Social Security and Medicare taxes still apply, and both deductions have caps and income phase-outs, so ask a tax professional if your situation is complicated.
Which calculators help with time cards, raises and time off?
Payroll systems record hours as decimals, so 7 hours 45 minutes becomes 7.75 hours. The minutes to decimal hours converter handles one entry or a full weekly time card. For leave, the PTO accrual calculator divides your yearly PTO hours by your pay periods or by the hours you work. The salary increase calculator shows a raise as a percent and as new hourly and yearly pay.
