How the $27.00 is worked out

Half of $18 is $9.00. Add it to the $18 you already earn and the overtime rate is $27.00. The $9.00 half is the only part the 2025 no-tax-on-overtime deduction lets you subtract from taxable income, up to $12,500 a year. The deduction calculator turns your overtime hours into that figure.

When you're owed more than $27.00

If you also get a shift differential or a production bonus, your regular rate is higher than $18 and so is your overtime rate. California pays $36.00 after 12 hours in a day. See the blended rate calculator for mixed weeks and the double time calculator for 2x hours.
