Are shift differentials taxed?

Yes. Differentials are wages and are taxed and FICA-taxed like regular wages.

How is overtime calculated when I have multiple rates?

FLSA requires a weighted-average regular rate including all non-discretionary differentials and bonuses. Overtime is 1.5x that weighted rate.

Why is my overtime more than 1.5x base?

Because it includes shift differentials. 1.5 times (base plus $4 differential) is bigger than 1.5 times base alone.

Nurse Paycheck Guide (Shifts, Overtime, Travel Nurse)

Nurse pay can look unusual. Multiple rates per shift, weekend and holiday uplifts, mandatory overtime in some hospitals, and (for travel nurses) tax-free stipends layered on top of taxable wages. Here is how each maps onto a stub.

PayslipIQ is not a CPA firm, law firm, financial advisor, payroll provider, or tax authority. Always verify your paycheck, deductions, withholdings, and tax position with your employer's payroll department, a qualified CPA, the IRS, your state tax authority, or another appropriately qualified professional. Calculations are estimates; your actual paycheck may differ based on factors specific to your employer, location, benefits elections, and personal tax situation.

Shift differentials

Hospitals pay extra for evening, night, weekend and holiday shifts. The differential is either a flat dollar amount per hour or a percentage. Differentials count for FLSA overtime: a 12-hour night shift with a $4 differential has overtime calculated at 1.5 times (base + $4), not 1.5 times base.

Mandatory overtime

Some states (CA, NY, NJ, IL, MN, OR, PA, RI, WV) restrict mandatory overtime for nurses. Voluntary overtime is paid at FLSA-required rate (1.5x weighted regular rate above 40 per week, plus state daily-OT rules where applicable).

Travel nurse stipends

Travel nurses often earn a low taxable hourly rate plus tax-free stipends for housing, meals and incidentals. The IRS allows tax-free stipends only if the nurse maintains a separate tax home and the assignment is genuinely temporary (under 12 months). Misuse triggers audit risk. Talk to a CPA before structuring travel nurse pay.
