How your paycheck is taxed in North Carolina
A North Carolina paycheck is reduced by federal income tax, Social Security (6.2%), Medicare (1.45%), and a flat 3.99% state income tax. The federal side uses the 2026 standard deduction of $16,100 (single) or $32,200 (joint) and seven brackets from 10% to 37%. The state side is described below. The standard deduction is $12,750 (single) and $25,500 (joint) and is not indexed.
Formula
Net pay = Gross pay - Pre-tax deductions - Federal income tax - Social Security - Medicare - North Carolina income tax - After-tax deductions. Federal taxable income is gross minus pre-tax deductions minus the standard deduction. North Carolina taxable income is wages minus the state standard deduction.

Worked examples: single filer, paid biweekly
Each row is a single filer with no pre-tax deductions, using the 2026 federal tables and the North Carolina rules above. The $75,000 example: federal taxable income is $58,900 after the $16,100 standard deduction, giving $7,670.00 of federal tax (10% on the first $12,400, 12% up to $50,400, 22% on the rest). Social Security is 6.2% of $75,000 = $4,650.00, Medicare is 1.45% = $1,087.50, and North Carolina tax on $62,250 of state taxable income is $2,483.78. Net pay is $59,108.73 a year, or $2,273.41 every two weeks.
| Salary | Federal tax | Social Security | Medicare | North Carolina tax | Net per year | Net per paycheck |
|---|---|---|---|---|---|---|
| $50,000 | $3,820 | $3,100 | $725 | $1,486 | $40,869 | $1,571.87 |
| $75,000 | $7,670 | $4,650 | $1,088 | $2,484 | $59,109 | $2,273.41 |
| $100,000 | $13,170 | $6,200 | $1,450 | $3,481 | $75,699 | $2,911.49 |
Effective total tax rates in these examples run from 18.3% at $50,000 to 24.3% at $100,000. Married filers with the same household income pay less federal tax because the joint standard deduction and brackets are twice as wide.
How a flat tax changes with income
Because every dollar of taxable income is taxed at 3.99%, North Carolina tax rises in a straight line once you are past the deduction and exemption. In the examples above it is $1,486 at $50,000 (2.97% of gross), $2,484 at $75,000 (3.31%), and $3,481 at $100,000 (3.48%). The federal side is what makes the total effective rate climb faster than that, since federal brackets step from 12% to 22% at $50,400 of taxable income and to 24% at $105,700.
Hourly pay in North Carolina
Hourly workers are annualized the same way: rate x hours per week x 52. At $20 an hour for 40 hours, gross pay is $41,600 a year or $800 a week. Federal income tax is $54.08 a week, Social Security $49.60, Medicare $11.60, and North Carolina tax $22.14, leaving $662.59 per weekly paycheck. Overtime raises the annualized figure and can push a few dollars into the next federal bracket, but only those dollars are taxed at the higher rate.
Married filing jointly on $75,000
A married couple filing jointly with $75,000 of combined wages gets the $32,200 joint standard deduction and brackets twice as wide, so federal income tax falls to $4,640.00 from $7,670.00 for a single filer, and North Carolina tax is $1,975.05 instead of $2,483.78. Social Security and Medicare do not change with filing status. Take-home pay for the couple is $62,647.45 a year, or $2,409.52 per biweekly paycheck.
