North Carolina's Flat 3.99%, and Still Falling
North Carolina finished phasing its flat income tax down to 3.99% on January 1, 2026, from 4.25% in 2025, and statutory triggers can push it lower toward 2.99% if state revenue targets are met. The state pairs that low rate with a genuine standard deduction, $12,750 for single filers and $25,500 for married couples. A single filer earning $80,000 shelters $12,750, owes about $2,683 in state tax, and lands at an effective rate near 3.35%, among the lightest wage-tax burdens of any state that taxes income at all.
A Real Standard Deduction Keeps the Effective Rate Low
Unlike Pennsylvania, which taxes from the first dollar, North Carolina's $12,750 single / $25,500 married standard deduction meaningfully lowers what you actually pay. On $80,000 the effective rate (3.35%) sits well below the 3.99% headline because the first $12,750 is shielded entirely. The combination of a flat low rate and a flat deduction makes North Carolina one of the simplest states to estimate: subtract the deduction, multiply by 3.99%, and you have your state tax.
North Carolina Does Tax Retirement Income
One contrast worth knowing: unlike Illinois or Georgia, North Carolina taxes most retirement income at the same flat 3.99%, pensions and 401(k)/IRA withdrawals are generally included. The notable exception is the Bailey settlement, which exempts certain federal, state, and local government pensions for workers vested before August 1989. For most private-sector retirees, though, North Carolina's retirement income is taxed like wages, so the low rate does some of the work that an exemption does elsewhere.
No Local Income Tax
No North Carolina city or county levies a local income tax, so the flat 3.99% plus the standard deduction is the entire sub-federal picture on your wages. There is no Ohio-style municipal tax and no Pennsylvania-style local Earned Income Tax to track. Property tax is moderate by national standards, which means North Carolina's overall tax profile is genuinely on the lighter side once you account for everything, not just the income line.
Planning Around a Low, Flat Rate
With a flat 3.99% and no brackets to manage, timing income in North Carolina will not shift your state rate, a bonus or Roth conversion is taxed at the same 3.99% as your salary. A traditional 401(k) dollar saves that 3.99% in state tax plus your federal bracket. Because the state rate is so low, the federal side dominates your take-home math here; the calculator above lets you see how each pre-tax dollar splits between federal and state savings.
The Bailey Exemption: Why Some North Carolina Retirees Pay Zero
North Carolina's standout retirement feature is the Bailey exemption, the result of a state Supreme Court settlement. Federal, North Carolina state, and local government retirees, including military, who had at least five years of creditable service vested before August 12, 1989, owe no North Carolina income tax on those retirement benefits at all. For a long-tenured federal civil servant or a military careerist who started service before that date, that can mean a pension taxed at 0% by the state for life. Retirees who do not meet the Bailey vesting date pay the flat 3.99% on pension, 401(k), and IRA income like everyone else, since North Carolina otherwise taxes retirement income. North Carolina has also broadened relief for military retirement pay in recent years, so career servicemembers should check current rules before assuming their pension is taxable.
The Rate Is Still Coming Down
North Carolina's flat rate has been falling on a schedule: 4.5% in 2024, 4.25% in 2025, and 3.99% for 2026. Under the 2023 budget law, the rate drops further whenever General Fund revenue clears statutory thresholds. Collections have cleared the bar for the next step, so the rate is set to fall to 3.49% on January 1, 2027, and the law allows additional reductions through 2034 that could carry it toward 2.49% if revenue keeps pace (NCDOR; Tax Foundation). For planning, treat 3.99% as a ceiling that is likely to keep dropping, which makes North Carolina one of the more predictable low-tax states to project multi-year take-home pay in.
Setting Withholding and Filing: NC-4 and D-400
You set North Carolina withholding on Form NC-4 (or the simpler NC-4 EZ), which determines your state allowances independently of the federal W-4. Residents file Form D-400 by April 15, e-filed through the NCDOR portal. Because the rate is flat, there is no bracket management at filing; the standard deduction ($12,750 single, $25,500 married) does most of the work of keeping the effective rate below 3.99%. If you are a government or military retiree, the most important filing step is confirming whether your benefits qualify for the Bailey exemption, since that single determination can zero out your state tax on retirement income.
Social Security and Medicare (FICA) are federal, so they come out the same in North Carolina as in every other state. The main Paycheck Calculator walks through the full federal side, including the Social Security wage base and the Additional Medicare surtax.
