North Carolina uses a flat state income tax of 4.0% in 2026 — the same rate applies to every dollar of taxable income, which makes your paycheck easy to predict. On a $75,000 salary, a single filer pays about $2,993 in state tax and takes home roughly $58,600 a year (about 78.1% of gross) after federal, state, and FICA withholding.

North Carolina's 4.0% rate is below the 4.8% average among states that tax wage income. Because the rate is flat, a raise never pushes part of your income into a higher state bracket — every extra dollar is taxed at the same 4.0%, unlike the federal system where higher earnings hit progressively higher brackets.

Remember that FICA is separate from income tax and is not affected by your state. Every worker pays 6.2% for Social Security on the first $184,500 of wages (the 2026 wage base) plus 1.45% for Medicare on all wages. Pre-tax 401(k) and HSA contributions lower your federal and state income tax but do not reduce FICA — a detail that trips up a lot of first-time budgeters.

North Carolina's flat tax has been ratcheting down on a legislated schedule, with further cuts already written into law contingent on revenue triggers — the state has gone from a top rate near 7.75% in the early 2010s to one of the lower flat rates in the country. Combined with the Research Triangle and Charlotte banking sector's salary growth, the falling rate has made North Carolina a standout for real after-tax income gains over the past decade.
