Yes, North Carolina has a state income tax
North Carolina taxes your income at the state level. As of 2024, the state income tax rate is a flat 4.99% on all taxable income, regardless of how much you earn. This rate applies to wages, self-employment income, investment gains, and other sources of taxable income.
The state collects this tax through withholding from paychecks, quarterly estimated payments if you're self-employed, and annual filings with the North Carolina Department of Revenue. You'll file both a federal return and a separate North Carolina return each year.

How the 4.99% tax rate works
North Carolina uses a single flat tax rate rather than tax brackets. This means whether you earn $30,000 or $300,000 per year, the state taxes your income at the same 4.99% rate. The rate applies only to income above your standard deduction.
For the 2024 tax year, the standard deduction is $10,750 for single filers and $21,500 for married couples filing jointly. You subtract this amount from your total income before calculating the 4.99% tax. For example, if you're single and earn $50,000, you'd pay tax on $39,250 ($50,000 minus $10,750), which equals $1,956.69 in state income tax.
North Carolina also allows you to claim a dependent exemption of $2,500 per dependent, which further reduces your taxable income. These deductions stack with your standard deduction.
Who must file a North Carolina tax return
You must file a North Carolina return if you live in the state and your income exceeds the filing threshold. For 2024, that threshold is generally the same as your standard deduction—$10,750 for single filers and $21,500 for married couples filing jointly. If you earn more than these amounts, you're required to file.
You must file even if you don't owe state tax in some situations: if you had state income tax withheld from your paychecks, you may be due a refund. If you're self-employed, you must file to pay self-employment tax and estimated taxes. If you received certain credits or deductions, filing may be necessary to claim them.
North Carolina residents who work out of state may still owe North Carolina tax on income earned in the state, depending on where the income was earned and your residency status. If you moved to or from North Carolina during the year, you may file as a part-year resident.
Withholding and paycheck deductions
Your employer withholds North Carolina state income tax from your paycheck based on the W-4 form you complete. The withholding amount depends on your filing status, the number of dependents you claim, and any additional withholding you request. You can adjust your withholding at any time by submitting a new W-4 to your employer.
If too much tax is withheld, you'll receive a refund when you file your return. If too little is withheld, you'll owe when you file. To avoid a large bill at tax time, you can increase your withholding on your W-4, or if you're self-employed, make quarterly estimated payments.
The North Carolina Department of Revenue provides a withholding calculator on its website to help you determine whether your current withholding is correct. This is especially useful if you have multiple jobs, a spouse who works, or significant non-wage income.
Self-employment and quarterly estimated taxes
If you're self-employed or have income not subject to withholding, you must make quarterly estimated tax payments to North Carolina. These payments cover both state and federal taxes and are due on April 15, June 15, September 15, and January 15 of the following year.
To calculate your estimated payment, you estimate your total income for the year, subtract deductions, and calculate 4.99% of the result. You then divide that amount by four and pay one quarter each due date. If you underestimate significantly, you may owe penalties and interest when you file your annual return.
Many self-employed workers use tax software or work with a tax professional to calculate estimated payments accurately. The North Carolina Department of Revenue website has worksheets to help you calculate these payments yourself.
Tax credits and deductions available in North Carolina
Beyond the standard deduction and dependent exemption, North Carolina offers several credits that reduce your tax bill dollar-for-dollar. The Dependent Care Credit helps if you pay for childcare or elder care to enable you to work. The Education Credit applies to tuition and fees paid for higher education. The Property Tax Credit reduces tax for homeowners and renters with low to moderate income.
North Carolina also allows deductions for contributions to certain retirement accounts, such as traditional IRAs and self-employed SEP-IRAs. If you paid property taxes or made charitable donations, you can deduct those on your state return if you itemize deductions instead of taking the standard deduction.
Military members and veterans may may have access to for additional credits. If you received unemployment benefits during the year, a portion may be excluded from your taxable income. Review the North Carolina Department of Revenue website or speak with a tax professional to determine which credits and deductions explore to your situation.
Filing your North Carolina tax return
You can file your North Carolina return electronically or by mail. Most people file electronically because it's faster and reduces errors. You can use tax software, file through a tax professional, or use free filing options if your income is below a certain threshold.
The North Carolina Department of Revenue offers free tax preparation information through the Volunteer Income Tax information (VITA) program for low-income residents. You can find a VITA site near you on the IRS website. Many libraries and community organizations also offer free tax preparation during tax season.
Your North Carolina return is due on the same date as your federal return—typically April 15. If you file for an extension, your state return is also extended. File your return as early as possible if you expect a refund, since refunds are processed in the order they're received.
Frequently Asked Questions
Do I have to pay North Carolina income tax if I work out of state?
It depends on where you work and where you live. If you live in North Carolina but work in another state, you generally owe tax to the state where you earned the income. However, North Carolina allows a credit for taxes paid to other states to avoid double taxation. If you live out of state but work in North Carolina, you owe North Carolina tax on that income. Speak with a tax professional if your situation is complex.

The North Carolina Department of Revenue can assess penalties and interest on unpaid taxes. If you owe a refund, you forfeit it if you don't file within three years. The state can also place a lien on your property or garnish wages for unpaid taxes. If you haven't filed in past years, contact the Department of Revenue about filing back returns.

No. North Carolina does not allow a deduction for federal income tax paid. However, you can deduct state income tax paid on your federal return if you itemize deductions. You cannot deduct both state and local taxes and sales taxes on your federal return—you must choose one or the other.
