Taxes typically take about 20% to 35% out of a paycheck in NC, depending on your income, filing status, and any pre-tax deductions. Three things are pulled from every check: federal income tax (10% to 37% on a sliding scale), a flat 3.99% North Carolina state income tax, and FICA taxes totaling 7.65% for Social Security and Medicare. No North Carolina city or county adds a local income tax, so those are the only government deductions on your stub.
North Carolina State Income Tax
North Carolina uses a flat income tax rate, so every resident pays the same percentage regardless of what they earn. For tax year 2026, that rate is 3.99%.1NCDOR. Tax Rate Schedules The rate has been coming down (4.5% in 2024, 4.25% in 2025), and further reductions are possible depending on state revenue triggers.
Your employer calculates the state withholding using tables published by the North Carolina Department of Revenue, applying the allowances and filing status you list on Form NC-4.2North Carolina General Assembly. North Carolina Code 105-163.2 – Employers Must Withhold Taxes Before the 3.99% is applied, the state subtracts its own standard deduction. For 2025 those amounts were $12,750 for single filers, $25,500 for married filing jointly, and $19,125 for head of household; the 2026 figures typically tick up slightly.
If you never file an NC-4, your employer must withhold as if you are single with zero allowances, which usually pulls more than necessary out of each check.3NCDOR. NC-4 Employee’s Withholding Allowance Certificate
Federal Income Tax
Federal income tax is usually the largest line on your pay stub. Your employer withholds it based on your earnings and what you put on Form W-4.4Office of the Law Revision Counsel. 26 USC 3402 – Income Tax Collected at Source The system is progressive: higher slices of your income are taxed at higher rates. The 2026 brackets:
- 10%: up to $12,400 single / $24,800 joint
- 12%: $12,401 to $50,400 single / $24,801 to $100,800 joint
- 22%: $50,401 to $105,700 single / $100,801 to $211,400 joint
- 24%: $105,701 to $201,775 single / $211,401 to $403,550 joint
- 32%: $201,776 to $256,225 single / $403,551 to $512,450 joint
- 35%: $256,226 to $640,600 single / $512,451 to $768,700 joint
- 37%: over $640,600 single / over $768,700 joint
These rates hit taxable income, not gross pay. For 2026 the federal standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.5Internal Revenue Service.

Form W-4 tells your employer your filing status, dependents, and whether you hold a second job.6Internal Revenue Service. About Form W-4, Employee’s Withholding Certificate If you don’t submit one, the employer must withhold as single with no adjustments, which generally overwithholds.7Internal Revenue Service. Withholding Compliance Questions and Answers Update your W-4 after a marriage, a new child, or a second job to keep withholding close to your actual tax bill.
Social Security and Medicare (FICA)
Every paycheck also has FICA deductions for Social Security and Medicare. These are separate from income tax and fund retirement, disability, and health benefits. The employee share:
- Social Security: 6.2% of gross wages, up to a 2026 wage base of $184,500. Once your year-to-date pay passes that cap, Social Security tax stops for the rest of the year.8Social Security Administration. Contribution and Benefit Base
- Medicare: 1.45% of all gross wages, no cap.9Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax
Combined, that’s 7.65% off your gross pay until you hit the Social Security cap. Your employer pays a matching 7.65%, but that doesn’t show up as a deduction on your stub.
Additional Medicare Tax for Higher Earners
An extra 0.9% Medicare tax applies to wages above certain thresholds, and employers do not match it. The thresholds are $200,000 for single filers and heads of household, $250,000 for married filing jointly, and $125,000 for married filing separately. Your employer starts withholding the extra 0.9% once your wages pass $200,000 for the calendar year regardless of filing status; joint filers reconcile on their tax return.10Internal Revenue Service.

Why Bonus Checks Look Smaller
Bonuses, commissions, overtime, and vacation payouts count as supplemental wages and are often withheld at flat rates. Federal rules let your employer withhold a flat 22% from supplemental pay instead of running the regular bracket calculation.11Internal Revenue Service. 2026 Publication 15-T – Federal Income Tax Withholding Methods Above $1 million in supplemental wages for the year, the rate jumps to 37% on the excess.
For state tax, employers can withhold a flat 4.09% on supplemental wages paid separately from your regular check.12NCDOR. 2026 Income Tax Withholding Tables and Instructions for Employers FICA still applies at the standard rates. A $5,000 bonus in North Carolina typically loses roughly $1,500 to $1,800 to withholding before it hits your account.
Pre-Tax Deductions That Shrink Your Withholding
Some voluntary deductions come out before taxes are calculated, which lowers what’s withheld. The common ones:
- 401(k) or 403(b) contributions reduce federal and state taxable income, but FICA still applies to that money.
- Health insurance premiums paid through a Section 125 cafeteria plan come out pre-tax.
- HSA contributions made through payroll are excluded from federal income tax, state income tax, and FICA.
- FSA contributions for healthcare or dependent care reduce wages for both income tax and FICA.
The tax savings mean a $500 monthly 401(k) contribution doesn’t drop your take-home by a full $500. For a worker in the 22% federal bracket, the actual reduction in net pay lands closer to $350 to $400 once lower federal and state withholding are factored in.
A Worked Example
Consider a single filer in North Carolina earning $60,000 a year with no pre-tax deductions, paid every two weeks. Gross pay is roughly $2,308 per check. Withholding comes out approximately:
- Federal income tax: about $230
- North Carolina income tax: about $70
- Social Security: about $143
- Medicare: about $33
Net pay lands near $1,832 per paycheck. Your exact figures will shift with your W-4 and NC-4 elections, any pre-tax retirement or health contributions, and any extra withholding you’ve asked for. Your stub should break each deduction into its own line, and comparing it to the numbers above is the fastest way to catch an error before it compounds over a year.
