Paycheck guide for nurses

Nursing paychecks are some of the hardest to predict. Shift differentials for evenings, nights, weekends, and holidays. Overtime that can kick in after 8 hours or 12 hours depending on your facility. Per diem assignments at different rates. Float pool pay. Multiple facility W-2s. Union dues. License renewals. Every variable changes your take-home differently, and they all stack on top of each other in a single pay period.

If you have ever looked at your pay stub after a busy stretch and thought “I worked 60 hours with night differential and somehow only took home $200 more than last period” — you are not alone. The problem is not that you are being cheated. The problem is that payroll math is layered, and every extra dollar you earn gets taxed at your marginal rate, not your average rate.

Why nurse paychecks are hard to predict

Most workers have one pay rate. Nurses can have four or five rates in a single pay period. Your base rate, plus an evening differential, plus a night differential, plus a weekend premium, plus overtime on top of whichever rate you were earning when the overtime kicked in. Each rate stacks into your gross pay, and your gross pay determines which tax bracket your withholding lands in.

On top of that, overtime thresholds vary by employer and state. Some facilities pay overtime after 8 hours per shift (common in California). Others use the standard 40 hours per week. Some pay double-time after 12 hours. If you pick up an extra shift, you need to know which rule applies to know what your overtime rate actually is — and how much of that overtime you actually keep.

Per diem and travel nursing add another layer. Per diem rates are typically $5 to $15 per hour higher than staff rates to compensate for no benefits, but the full amount is taxable income. Travel nursing stipends may be partially non-taxable (housing, meals), but the taxable portion still hits your withholding. And if you work at multiple facilities, each employer withholds independently — meaning each one may under-withhold because they do not see your total income picture.

What hits your paycheck

Here is every variable that can change your nursing take-home from one period to the next:

• Shift differentials: evening (+$3 to $5/hr), night (+$5 to $8/hr), weekend (+$4 to $6/hr), holiday (time-and-a-half or double-time at many facilities). These are added to your base rate before overtime calculations.
• Overtime: 1.5x your effective rate after 40 hours per week (or 8 to 12 hours per shift, depending on state law and facility policy). Double-time after 12 hours in some states. Your overtime rate includes differentials — if you are earning $38 base plus $6 night differential, your OT rate is $66/hr (1.5 × $44), not $57 (1.5 × $38).
• Per diem and travel premiums: higher hourly rates ($45 to $65/hr depending on specialty and market) but no employer-subsidized benefits. The full hourly rate is taxable.
• Certification pay: CCRN, CEN, CNOR, and other certifications often add $1 to $3/hr or a flat bonus per pay period.
• Union dues: typically $40 to $100 per month, deducted after tax. This is money that reduces your take-home but does not reduce your taxable income.
• License renewal fees: some employers deduct these from paychecks, either as a lump sum or spread across pay periods.
• Health insurance: single coverage vs. family coverage can differ by $200 to $500 per month. Hospital systems often offer multiple tiers (employee-only, employee + spouse, employee + children, family). Pre-tax deductions reduce your taxable income.
• Retirement contributions: hospital systems typically offer 403(b) plans (the nonprofit equivalent of a 401(k)). A traditional 403(b) contribution reduces your federal and state taxable income. A Roth 403(b) does not — it comes out after tax.

A realistic scenario

Let's walk through a real pay period. Say you are a staff RN earning $38/hr base, paid biweekly, single filer in a state with income tax. This period you worked:

• 72 regular hours at your $38 base rate = $2,736
• 8 overtime hours at $57/hr (1.5 × $38) = $456
• 16 night-shift hours with a $6/hr differential = $96 in additional differential pay
• 8 weekend hours with a $4/hr differential = $32 in additional differential pay

Your gross pay for this period: $3,320. That is before a single deduction.

Now the deductions start. Federal withholding takes a cut based on annualizing that $3,320 over 26 pay periods — the system sees $86,320 annually and withholds accordingly. FICA takes 7.65% ($254). Your state takes its percentage. Then your pre-tax 403(b) contribution (say 6% of gross, about $199) reduces your federal and state taxable income but not your FICA taxable income. Your health insurance premium ($180 pre-tax) reduces all three. Union dues ($45 after-tax) come straight off the bottom.

By the time everything is subtracted, your $3,320 gross becomes somewhere around $2,300 to $2,500 in take-home depending on your state and filing status. That $552 in overtime and differentials? After taxes, you kept roughly $350 to $380 of it.

When your paycheck changes and you did not expect it

These are the most common reasons a nurse's paycheck changes without warning:

• Differential rate changed: your facility updated night or weekend premium rates. Even a $1/hr change across 16 differential hours means $16 less (or more) in gross, which after taxes moves your take-home by about $10 to $12.
• Overtime threshold changed: you moved to a facility that pays OT after 40 hours weekly instead of 8 hours per shift. Same hours, different overtime eligibility.
• Crossed a FICA wage base: if you earn enough, your Social Security tax (6.2%) stops once you hit $184,500 in 2026 year-to-date wages. When it stops, your take-home jumps by about $2.35 per hour on a $38 base. It resets in January.
• Union dues increased: annual increases are common and often take effect at the start of a fiscal year. A $10/month increase means about $5 less per biweekly paycheck.
• Insurance tier changed at open enrollment: adding a spouse or child to your plan can increase premiums by $150 to $400 per month. That hits your take-home hard even if your hours did not change.
• Picked up extra shifts that pushed withholding higher: three extra shifts in one period can push your annualized income into the next federal bracket, increasing the withholding percentage on every dollar that period. You may get some back as a refund, but the paycheck feels smaller per-hour than expected.
• 403(b) auto-escalation: many hospital plans automatically increase your contribution by 1% each year. If you contribute 6% and it jumps to 7%, that is roughly $33 more per biweekly paycheck going to retirement — which is good for your future, but it means less cash now.

What TakeHome IQ does for nurses

TakeHome IQ is built for workers whose pay changes every period. Here is how it handles the complexity of nursing pay:

• Models shift differentials as additional earnings: enter your night, evening, weekend, and holiday hours separately. The app adds each differential to your base rate and shows you the gross build-up and the tax impact of each component.
• Shows overtime impact after taxes: see how much you actually keep from each overtime hour — not just the gross rate. The app factors in your marginal federal rate, FICA, and state taxes to show the real net per OT hour.
• Tracks year-to-date for FICA caps: enter your YTD earnings and the app tells you when your Social Security tax will stop, and how much your per-hour take-home increases after that point.
• Compares this paycheck to last: see exactly which line moved. Was it fewer night hours? A higher insurance premium? An increased 403(b) contribution? The comparison view shows the delta for each line item so you know what changed and by how much.
• Handles pre-tax and after-tax deductions correctly: 403(b) contributions reduce your federal and state tax but not FICA. Union dues do not reduce any tax. The app gets this right so your take-home projection matches your actual pay stub.

If your pay changes every period — and as a nurse, it almost certainly does — you deserve to know what your next paycheck looks like before payday. Not a rough guess. The actual number, with every tax line and deduction accounted for.

Frequently asked questions

Are shift differentials taxed differently than base pay?

No. Shift differentials are ordinary income taxed at the same rates as your base hourly pay. They increase your gross for that period, which may push withholding into a higher bracket, but the underlying tax rate is the same.

Why did my paycheck drop even though I worked the same hours?

Common causes for nurses: a differential rate changed, your overtime threshold shifted, union dues increased, insurance premiums changed at open enrollment, or your 403(b) contribution auto-escalated. Any single change can move your take-home by $50 to $200 per pay period.

How does per diem nursing pay affect my taxes?

Per diem hourly rates are typically higher to compensate for no benefits. The full amount is taxable as ordinary income. Without employer-subsidized insurance or retirement, your gross is higher but you may pay more in taxes and out-of-pocket benefits costs.
