Quick Answer: How Premium Pay Works

Holiday pay, double-time, and shift differentials are all forms of premium pay. Your employer offers them by policy or union contract. Federal law does not require any of them.

The part that catches most workers off guard is that premium pay counts as ordinary taxable income. There is no special “premium tax rate.” Your holiday hours are taxed exactly like your regular hours. To see the net, the Paycheck Calculator shows your take-home after federal, state, and FICA taxes.

What Each Type of Premium Pay Means

“Premium pay” is an umbrella term for extra pay you earn for when or how you work, not for extra hours. Three kinds show up most often on pay stubs.

Holiday pay. Extra compensation for working on a designated holiday, such as Thanksgiving or the Fourth of July. Some employers pay time-and-a-half, others pay double-time, and some just pay your normal rate plus a bonus.

Double-time. Twice your regular hourly rate. It usually applies to holidays, to hours worked beyond a daily threshold, or to a seventh consecutive workday, depending on company policy or a union agreement.

Shift differential. A bump for working less desirable hours, like overnight, evening, or weekend shifts. Hospitals, factories, warehouses, and call centers use it to staff hard-to-fill schedules.

None of these is the same as overtime. Overtime is the one premium federal law actually requires, and we will get to how the two interact.

Is Any of This Required by Law?

At the federal level, no.

The Fair Labor Standards Act (FLSA) does not require payment for time not worked, such as holidays, and it does not require extra pay for weekend or night work or double-time. The U.S. Department of Labor is explicit: these benefits are a matter of agreement between an employer and an employee.

The one federal requirement is overtime. Non-exempt employees must be paid at least 1.5x their regular rate for hours worked over 40 in a workweek. Working on a holiday or a Saturday does not trigger overtime “as such,” only crossing 40 hours in the week does.

States can go further. California, for example, requires daily overtime and double-time in certain situations. If you work in a state with its own rules, check both. But federal law sets the floor, and that floor does not include holiday or shift premiums.

How to Calculate Each Premium

The math is simpler than it looks. Here is how each one works, with numbers.

Holiday premium

If your base rate is $22 per hour and your employer pays time-and-a-half on holidays, you earn $33 per hour for holiday work ($22 x 1.5). Work an 8-hour holiday shift and that is $264 instead of $176.

Double-time

Double-time is 2x your base rate. At $22 per hour, double-time is $44 per hour. An 8-hour double-time shift pays $352.

Shift differential

Differentials come in two flavors:

Flat amount: a set dollar figure per hour, commonly $0.50 to $1.25. A $1.00 night differential on a $22 base makes your night rate $23 per hour.
Percentage: a percentage of your base, commonly 5% to 15% (healthcare and weekends often run higher). A 10% night differential on $22 adds $2.20, for a $24.20 night rate.

A stacked example

Say you work a night shift on a holiday. Base is $22 per hour, your employer pays a $1.50 night differential and time-and-a-half for the holiday. One common approach: apply the differential first, then the holiday multiplier on the combined rate. That gives ($22 + $1.50) x 1.5 = $35.25 per hour. Policies differ on stacking order, so read your handbook or contract to confirm how your employer layers them.

To sanity-check hourly math against your regular paycheck, the Hourly Paycheck Calculator is a quick way to convert rates and hours into gross and net pay.

How Shift Differentials Change Your Overtime

This is the part many workers, and some employers, get wrong. When you earn a shift differential and also work overtime, your overtime is not based on your plain base rate.

Under the FLSA, shift differentials must be included in your “regular rate” before overtime is calculated. The regular rate is a blended, weighted average of everything you earned that week for hours worked, including night and weekend differentials. Your 1.5x overtime is then figured on that higher blended rate, not on base pay alone.

A simple version: you work 45 hours, all at a $22 base, and 20 of those hours carried a $2 differential. Your straight-time earnings are (45 x $22) + (20 x $2) = $990 + $40 = $1,030. Your regular rate is $1,030 / 45 = $22.89. The overtime premium you are owed is the extra half-time on your 5 overtime hours: 5 x ($22.89 x 0.5) = $57.23 on top of straight time.

So differentials push your overtime rate up. If your employer calculates overtime on base pay only, you may be underpaid. Our overtime deep dive in Overtime, Bonus, and Commission Take-Home walks through more examples.

How Premium Pay Is Taxed (The Myth-Buster)

Keep this section handy. Holiday pay, double-time, and shift differentials are ordinary taxable wages. Same federal income tax, same state income tax, same FICA as your base pay. There is no special premium tax bracket or penalty rate.

FICA still applies the usual way: 6.2% Social Security up to the annual wage base, 1.45% Medicare on all wages, plus the 0.9% Additional Medicare Tax over the filing-status threshold. For the full breakdown, see FICA Taxes Explained.

So why do big premium checks feel over-taxed? Withholding. When one paycheck is unusually large, payroll withholding tables can treat that period as if you earn that much all year, so a bigger slice is withheld for that check. It is not a higher tax rate. It evens out when you file your annual return.

Two wrinkles worth knowing:

Lump-sum premiums. If a premium is paid as a separately identified lump sum (a flat $200 holiday bonus rather than hours x rate), your employer may use supplemental withholding, a flat 22% federal rate in 2026. That is a withholding method, not a different tax. See Overtime, Bonus, and Commission Take-Home for how supplemental wages work.
No Tax on Overtime. The new deduction covers only the FLSA-required half-time (0.5x) portion of overtime pay. It does not cover double-time, holiday premiums, or shift differentials. If you assumed your holiday hours qualify, they do not. Our guide to the 2026 overtime tax deduction explains exactly what counts, and the No Tax on Tips post covers the sibling deduction for tipped workers.

Estimate Your Real Take-Home

Gross premium pay is easy to figure. What you actually keep depends on your state, your filing status, and your other deductions.

The fastest way to model it is to run your numbers per pay period. Enter your base hours, then add premium hours as an elevated rate or as taxable extra income, and check the net. Because state income tax varies widely, a night differential can land differently for a nurse in Texas than for one in Oregon.

Pay44 is built for exactly this. Model a heavy holiday week or a stretch of night shifts and see the per-paycheck take-home after federal, state, and FICA taxes. The Time-and-a-Half Calculator handles the overtime side, and you can download the app to run scenarios on your phone before you pick up that extra shift.

Frequently Asked Questions

Is holiday pay taxed differently than regular pay?

No. Holiday pay, double-time, and shift differentials are ordinary taxable wages, subject to the same federal and state income tax and FICA. There is no special premium tax rate.

Does the FLSA require my employer to pay extra for holidays, nights, or weekends?

No. Federal law only requires overtime at 1.5x for hours over 40 in a workweek. Holiday, night, and weekend premiums come from employer policy or a union contract, and some states add their own rules.

How do I calculate double-time pay?

Double-time is 2x your regular hourly rate for each qualifying hour. A $25 per hour base rate becomes $50 per hour for double-time hours.

How is shift differential calculated?

Either a flat amount per hour (commonly $0.50 to $1.25) or a percentage of your base rate (commonly 5% to 15%), added to base pay for the qualifying hours.

Does shift differential affect my overtime rate?

Yes. Differentials must be included in your FLSA regular rate, so overtime is calculated on the higher blended rate, not just your base pay.

Does No Tax on Overtime cover double-time or holiday pay?

No. Only the FLSA-required half-time (0.5x) overtime premium qualifies for the deduction. Double-time, holiday, and shift-differential premiums do not.

Why did my holiday or premium check feel over-taxed?

A larger gross in one pay period can push that period’s withholding higher, and it reconciles on your annual tax return. Nothing is taxed at a special premium rate.
