North Carolina Payroll Taxes Guide →Short Answer
This North Carolina paycheck calculator estimates net take-home pay after federal income tax withholding, Social Security (6.2%), Medicare (1.45%), and North Carolina income tax withheld at a flat 4.35% for 2025 (the 4.25% flat rate plus a 0.1% NC-30 buffer) applied after the North Carolina standard deduction and $2,500 allowances. For a single filer earning $65,000 per year paid biweekly with no allowances, gross pay is $2,500.00 per period and North Carolina net take-home is approximately $1,993.87. North Carolina has no employee unemployment contribution and no local city wage tax, so the only income taxes on your stub are federal and the flat 4.35% state line.
Key Takeaways
- North Carolina withholds a flat 4.35% for 2025. That is the 4.25% flat individual income tax rate plus a deliberate 0.1% buffer built into the NC-30 tables, so most workers are not under-withheld and reconcile to 4.25% on Form D-400.
- The rate is falling on a schedule: the individual rate is 4.25% for 2025, 3.99% for 2026 (4.09% withholding), and 3.49% for 2027. Withholding always runs 0.1 point above the income tax rate.
- Like Georgia, North Carolina builds a real standard deduction into withholding: $12,750 for single, married, or surviving spouse, and $19,125 for head of household. Each NC-4 allowance removes another $2,500.
- Because of that deduction, the effective North Carolina rate is well below 4.35% at low and moderate incomes.
- A traditional 401(k) deferral reduces North Carolina tax. NC income tax starts from federal adjusted gross income, so a deferral already excluded from federal wages is excluded from NC wages too. A $7,800 deferral saves about $339 of North Carolina withholding.
- Section 125 cafeteria-plan medical premiums reduce federal wages, North Carolina wages, and Social Security and Medicare wages.
- North Carolina has no employee-paid unemployment tax and no local city income tax. There is no Charlotte or Raleigh earnings tax, and unemployment insurance is funded entirely by employers.
- Bonuses and supplemental wages follow separate federal withholding rules (flat 22% or aggregate method) and the same flat North Carolina rate. For supplemental pay use the Bonus Tax Calculator and see the Bonus Tax Withholding Guide.

How This Calculator Works
Hourly Mode: Gross Pay Per Period
Gross pay per period equals the hourly rate multiplied by hours worked per week, then scaled to the pay period. For biweekly pay: hourly rate × hours per week × 2. For weekly: hourly rate × hours per week. For semi-monthly and monthly: hourly rate × hours per week × (52 ÷ periods per year).
Salary Mode: Gross Pay Per Period
Gross pay per period equals annual salary divided by the number of pay periods per year. Weekly: ÷ 52. Biweekly: ÷ 26. Semi-monthly: ÷ 24. Monthly: ÷ 12.
Which Wages North Carolina Taxes
North Carolina income tax begins with your federal adjusted gross income, so the wages North Carolina withholds on are the same wages that are subject to federal income tax withholding. That has a clean, practical result on a paycheck:
- Federal taxable wages = gross − Section 125 medical − 401(k) elective deferral.
- North Carolina taxable wages = the same base as federal, then further reduced by the North Carolina standard deduction and $2,500 per allowance before the rate is applied.
- FICA wages (Social Security and Medicare) = gross − Section 125 medical. The 401(k) deferral does not reduce FICA.
Because North Carolina starts from federal income, a traditional deferral lowers the state line as well as the federal line, which is why the calculator shows a small North Carolina tax saving whenever you enter a 401(k) amount.
Social Security Tax
Social Security is 6.2% of annualized FICA wages up to the $176,100 wage base for 2025. The per-period amount is the annualized Social Security tax divided by pay periods. This calculator does not track year-to-date cumulative wages, so for workers approaching the wage base, actual withholding will stop mid-year once the limit is reached.
Medicare Tax
Standard Medicare is 1.45% on all FICA wages. The calculator adds the 0.9% Additional Medicare Tax on annualized FICA wages above $200,000, matching the employer withholding rule in IRS Topic 560: withholding starts once wages exceed $200,000 in a calendar year regardless of filing status. Final liability on Form 8959 uses filing-status thresholds ($200,000 single/HOH, $250,000 MFJ, $125,000 MFS).
Federal Income Tax Withholding
The calculator follows IRS Publication 15-T Worksheet 1A (Percentage Method for Automated Payroll Systems) for 2025:
- Annualize the per-period gross pay (multiply by pay periods per year).
- Subtract annualized Section 125 medical premiums and 401(k) elective deferrals to get federal taxable wages.
- Add Step 4a other income; subtract Step 4b additional deductions.
- Subtract the line 1g allowance: $12,900 for married filing jointly or $8,600 otherwise. If the W-4 Step 2 box is checked, subtract $0 instead. The result is the Adjusted Annual Wage Amount.
- Apply the Annual Percentage Method table for the W-4 filing status - the STANDARD schedule, or the Step 2 Checkbox schedule when the Step 2 box is checked - then divide the tentative annual withholding by pay periods.
- Subtract Step 3 dependent credits divided by pay periods, then add Step 4c extra withholding.
North Carolina Income Tax (Form NC-30 Annualized Method)
North Carolina follows the Annualized Wages Method in Form NC-30. The employer annualizes the wages, subtracts the standard deduction for the employee's Form NC-4 marital status, subtracts $2,500 for each allowance claimed, and multiplies the remainder by the withholding rate:
NC tax = 4.35% × ( annual wages − standard deduction − ($2,500 × allowances) )
The standard deduction is $12,750 for single, married, or surviving spouse employees, and $19,125 for a head of household. North Carolina's key twist is the rate itself: the flat individual income tax rate for 2025 is 4.25%, but the NC-30 tables withhold at 4.35%, a deliberate 0.1-point buffer so most workers are not under-withheld given rounding and mid-year changes. You reconcile to the true 4.25% liability when you file Form D-400. Because a real deduction sits inside the formula, the effective North Carolina rate is lower than 4.35% at low and moderate incomes and can reach zero for a lower earner with several allowances. Any extra North Carolina withholding you requested on Form NC-4 is added on top.
No North Carolina Employee Unemployment or Local Tax
North Carolina collects no employee unemployment contribution; the entire cost of North Carolina unemployment insurance falls on employers through the NC Division of Employment Security. North Carolina also has no local income taxes anywhere in the state, so there is no Charlotte or Raleigh city line comparable to an Ohio municipal tax or the Philadelphia Wage Tax. That leaves a North Carolina paycheck with only two income-tax lines, federal and the flat 4.35% state tax, plus FICA.
Real-World Paycheck Scenarios
Scenario 1: Salaried Single Filer in Charlotte
Devin earns $65,000 per year at a Charlotte logistics firm, paid biweekly, filing single with a standard federal W-4 and no allowances on Form NC-4. He has no 401(k) deferral and no cafeteria-plan premiums. His biweekly gross is $65,000 ÷ 26 = $2,500.00.
North Carolina detail: Devin's annual wages of $65,000 are reduced by the $12,750 standard deduction to $52,250, times 4.35% = $2,272.88 annual, divided by 26 = $87.42 per period. His effective North Carolina rate is only about 3.50% of gross, below the 4.35% withholding rate and even below the 4.25% statutory rate, because the standard deduction shelters the first $12,750. A worker in Georgia at the same salary pays a headline 5.19%, so North Carolina lands noticeably lighter.
Scenario 2: The 401(k) Deferral That Cuts North Carolina Tax
Renee earns $85,000 per year in Raleigh, paid biweekly, filing single with no allowances. She defers $300 per period to a traditional 401(k) ($7,800 per year). Because North Carolina starts from federal income, the deferral lowers her North Carolina line as well as her federal line.
Renee's federal and North Carolina wages are both $77,200 (gross less the $7,800 deferral), while her FICA wages stay at $85,000 because a 401(k) deferral never reduces Social Security and Medicare. Her North Carolina tax of $107.83 comes from ($77,200 − $12,750) × 4.35% ÷ 26. If she stopped the deferral, her North Carolina tax would rise to $120.88, so the deferral saves $7,800 × 4.35% = $339.30 per year of North Carolina withholding now, taxed later when she draws the retirement income; see the Pension and Annuity Income Tax Guide for how distributions are treated at the back end.
Practitioner Insight
The North Carolina detail that confuses people every year is the two-rate structure. The number they read in the news is 4.25% for 2025, but the number on their pay stub calculates to 4.35%. Both are correct. North Carolina deliberately withholds a tenth of a point higher than the income tax rate so that a typical worker is not left owing at filing time, and the difference washes out on the Form D-400 return. When a client swears the payroll department used the wrong rate, this is almost always what they are seeing.
The second recurring item is workers arriving from Georgia or a no-income-tax state who misjudge the North Carolina line. They see the flat rate and assume it behaves like Pennsylvania's gross-times-rate tax, but North Carolina subtracts a $12,750 standard deduction first, so the effective rate on a moderate salary is closer to 3.5% than to 4.35%. We always model the effective rate, not the headline, when someone is comparing a North Carolina offer with a job in another state.
A third one worth flagging: the NC-4 allowance count is the lever, and the NC-4 worksheet is genuinely more involved than the federal W-4 because it asks the employee to estimate deductions and credits. A client who filled out NC-4 hastily and claimed zero allowances when they qualified for several is over-withholding all year. When a North Carolina refund is unusually large, a too-low NC-4 allowance count is the first thing we check.
When This Calculator Gives a Less Accurate Estimate
- Nearest-dollar rounding: The official NC-30 method rounds the per-period withholding to the nearest whole dollar. This calculator keeps cents for consistency with the federal and FICA lines, so a specific stub may differ by a few cents from the rounded NC-30 figure.
- Scheduled rate changes: This calculator uses the 2025 withholding rate of 4.35%. For 2026 the rate drops to 4.09% (a 3.99% income tax rate), and to 3.49% income tax for 2027, so a paycheck from a different year will use a different rate.
- Very low earners with several allowances: Once the standard deduction and $2,500 allowances exceed annual wages, North Carolina withholding is zero. The calculator floors the state line at zero, which is correct, but the exact break-even depends on your specific allowance count.
- Roth 401(k) contributions: A Roth deferral is a post-tax deduction. It reduces neither federal nor North Carolina taxable wages. Do not enter it in the 401(k) field, which models traditional pre-tax deferrals only.
- Multi-state and remote workers: North Carolina has no reciprocity agreements with other states, so a resident of another state working in North Carolina is generally subject to North Carolina withholding on North Carolina-source wages. This calculator assumes North Carolina resident withholding.
- Year-to-date tracking and variable hours: The calculator annualizes a single consistent pay period. Social Security stops mid-year at the wage base, overtime and seasonal hours vary, and bonuses use supplemental federal withholding rules.
Frequently Asked Questions
What is the North Carolina state income tax withholding rate for 2025?
North Carolina withholds state income tax at a flat 4.35% for 2025. That rate is the 4.25% flat individual income tax rate plus a deliberate 0.1% buffer built into the NC-30 withholding tables so most employees are not under-withheld across the year. For payroll withholding, employers apply 4.35% to annual wages after subtracting the North Carolina standard deduction and $2,500 for each allowance claimed on Form NC-4. The true rate you settle to when you file Form D-400 is 4.25%.
Why is the North Carolina withholding rate higher than the income tax rate?
North Carolina sets the withholding rate 0.1 percentage point above the flat income tax rate on purpose. For 2025 the individual income tax rate is 4.25%, but the NC-30 employer tables withhold at 4.35%. The extra tenth of a point is a buffer that keeps most workers from being under-withheld given rounding and mid-year changes, and you reconcile to the true 4.25% liability when you file your Form D-400 return. For 2026 the pattern continues: a 3.99% income tax rate with 4.09% withholding.
How much is the North Carolina standard deduction in the withholding formula?
For withholding, the NC-30 percentage method subtracts an annual standard deduction of $12,750 for single, married, and surviving spouse employees, and $19,125 for a head of household. Each withholding allowance claimed on Form NC-4 removes another $2,500 from annual taxable wages before the 4.35% rate is applied. A married couple filing jointly who expect the larger $25,500 return standard deduction claim the extra amount through additional NC-4 allowances rather than a separate withholding tier.
Do 401(k) contributions reduce North Carolina state income tax?
Yes. North Carolina income tax starts from your federal adjusted gross income, and a traditional 401(k) or 403(b) elective deferral is already excluded from federal taxable wages, so it is excluded from North Carolina taxable wages too. A worker deferring $7,800 to a traditional 401(k) reduces North Carolina taxable wages by $7,800 and saves about $339 of North Carolina withholding at the 4.35% rate. The deferral still does not reduce Social Security and Medicare wages, which are based on gross pay less only Section 125 medical premiums.
Does North Carolina have local city income taxes on wages?
No. North Carolina does not allow cities, counties, or school districts to impose a local income tax on wages. Charlotte, Raleigh, Greensboro, Durham, and every other North Carolina jurisdiction collect no local wage or earnings tax, so there is no city line on a North Carolina pay stub comparable to the Ohio municipal income tax or the Philadelphia Wage Tax. The only income tax withheld from a North Carolina paycheck is the federal tax and the flat 4.35% state tax.
Do North Carolina employees pay state unemployment tax?
No. North Carolina unemployment insurance is funded entirely by employer contributions to the NC Division of Employment Security. Employees pay nothing toward North Carolina unemployment, so there is no employee unemployment line on a North Carolina paycheck. Employers pay State Unemployment Insurance on the first $34,200 of each worker's wages for 2026 (up from $32,600 in 2025), at a new-employer rate of 1.0% or an experience-rated rate between 0.06% and 5.76%. North Carolina also has no state disability insurance or paid-family-leave payroll tax deducted from wages.
How do I fill out Form NC-4 for North Carolina withholding?
Form NC-4 is North Carolina's employee withholding allowance certificate. You select a marital status, which sets your withholding standard deduction ($12,750 for single, married, or surviving spouse; $19,125 for head of household), and you enter the number of withholding allowances, each worth $2,500 in the NC-30 formula. The NC-4 allowance worksheet translates your expected deductions and credits into an allowance count; claiming more allowances lowers the North Carolina tax withheld from each paycheck. If you do not file a Form NC-4, the employer withholds as single with zero allowances.
Does North Carolina tax health insurance premiums paid through a cafeteria plan?
No. Employer-sponsored medical premiums paid through an IRC Section 125 cafeteria plan are excluded from federal taxable wages, and because North Carolina income tax begins with federal adjusted gross income, they are excluded from North Carolina taxable wages as well. Section 125 medical premiums also reduce Social Security and Medicare wages. In North Carolina, both a traditional 401(k) deferral and a Section 125 medical premium reduce the state taxable wage base.
What is the Social Security wage base for 2025?
The Social Security wage base for 2025 is $176,100. Social Security tax at 6.2% applies to wages up to this amount, and withholding stops once cumulative wages for the year exceed it. Medicare has no wage base limit and continues at 1.45% on all wages. Employers withhold an additional 0.9% Medicare surtax on wages above $200,000 regardless of filing status; final liability thresholds are $250,000 for married filing jointly and $125,000 for married filing separately.
How does a North Carolina paycheck compare to other states?
At the same gross salary, a North Carolina worker takes home less than a worker in Texas or Florida, which levy no state income tax, because North Carolina adds the flat state line. Compared with a graduated high-tax state like California or New York, North Carolina is simpler and often lighter because the rate never rises with earnings, and its standard deduction shelters the first slice of pay. North Carolina's 4.25% income tax rate is below Georgia's 5.19% and Illinois's 4.95%, and it is falling further on a legislated schedule. Compare directly with the Georgia, Texas, Florida, Illinois, and New York calculators.
Why does my actual North Carolina paycheck differ from this estimate?
This calculator estimates standard federal withholding, FICA, and the flat 4.35% North Carolina withholding after the NC standard deduction and allowances. Actual paychecks also reflect post-tax deductions such as Roth 401(k) contributions and garnishments, year-to-date cumulative Social Security tracking, the NC-30 nearest-dollar rounding, employer-specific payroll adjustments, mid-year W-4 or NC-4 changes, and any additional North Carolina withholding you requested on Form NC-4. The calculator assumes consistent pay each period and does not track cumulative wages across the year.
What To Do Next
Start by confirming two North Carolina-specific numbers before you trust any paycheck estimate. First, pull your most recent pay stub and check whether the state line calculates to about 4.35% of your wages after the North Carolina standard deduction, not 4.35% of gross with no deduction. If the number looks slightly higher than the 4.25% you read about, that is the deliberate NC-30 buffer, not an error. Second, check the allowance count on your NC-4 against the NC-4 worksheet, since each allowance is worth $2,500 off your North Carolina taxable wages.
If the allowance count is wrong, the fix is a new Form NC-4 submitted to your employer. Remember that the withholding rate runs a tenth of a point above the income tax rate, so a small year-end refund of North Carolina tax is the system working as designed.
For the full North Carolina employer picture, including the state unemployment wage base and filing frequencies, read the North Carolina Payroll Taxes guide.
