North Carolina has a state income tax that applies to most residents and workers

Yes, North Carolina charges state income tax on wages, retirement income, and other earnings. The tax rate is a flat 4.99% for the 2024 tax year, meaning everyone pays the same percentage regardless of income level. This is different from the federal income tax system, which uses tax brackets that increase with income.

The state also taxes certain types of investment income, including interest, dividends, and capital gains, though some retirement income sources are partially or fully exempt. North Carolina does not tax Social Security benefits, and certain military pensions receive preferential treatment under state law.

Who has to file a North Carolina state tax return

You must file a North Carolina state return if your income exceeds the filing threshold for your filing status. For the 2024 tax year, a single filer with gross income of $12,750 or more must file. The threshold is higher for married couples filing jointly, heads of household, and other filing statuses.

Even if your income falls below the threshold, you may want to file if you had taxes withheld from your paychecks or if you may have access to for state tax credits. Filing can result in a refund of overpaid taxes or allow you to claim credits like the Earned Income Tax Credit.

What income is taxed and what is exempt

North Carolina taxes W-2 wages, self-employment income, interest, dividends, and capital gains. Retirement account distributions from IRAs and 401(k)s are taxable, as are distributions from pensions — with some exceptions. The state also taxes income from rental properties, business ownership, and other sources.

Social Security benefits receive full exemption from state tax. Military pensions are exempt up to $35,000 per year for each may have access to veteran. Government employee pensions, including those from teachers and state workers, are taxable but may may have access to for a partial deduction depending on when you began receiving them. Certain disability payments and workers' compensation are also exempt.

How to file your North Carolina state return

You file North Carolina state taxes using Form D-400, which you submit to the North Carolina Department of Revenue. The form asks for your income from all sources, deductions, and credits. You can file by mail, electronically through the state's online system, or through tax software that supports North Carolina returns.

The deadline to file is April 15 of the year following the tax year, the same as federal taxes. If you need more time, you can request an extension, though this extends only the filing deadline — taxes owed are still due by April 15. The state charges interest and penalties on unpaid taxes after the deadline, even if you have filed an extension.

Tax withholding from your paycheck

Your employer withholds North Carolina state income tax from your paycheck based on the W-4 form you complete. The amount withheld depends on your income, filing status, and the number of dependents you claim. If too much tax is withheld, you receive a refund when you file your return. If too little is withheld, you owe when you file.

You can adjust your withholding at any time by submitting a new W-4 to your employer. This is useful if your income changes, you have a major life event, or you consistently owe money or receive a large refund. The state provides a withholding calculator on the Department of Revenue website to help you determine the correct amount.

Special situations: self-employment and quarterly taxes

If you are self-employed or have income that is not subject to withholding, you may need to pay estimated taxes to North Carolina quarterly. Estimated tax payments are due on April 15, June 15, September 15, and January 15. You calculate the amount based on your expected annual income and pay directly to the state.

Failure to pay estimated taxes when required can result in penalties and interest, even if you ultimately owe no tax or receive a refund. If your income is irregular or difficult to predict, you can adjust your quarterly payments as the year progresses. The Department of Revenue provides Form D-400ES to help you calculate estimated tax liability.

Frequently Asked Questions

Do I have to pay North Carolina income tax if I work in the state but live elsewhere?

Yes. North Carolina taxes income earned within the state regardless of where you live. If you work in North Carolina but live in another state, you may owe taxes to both states, though you can usually claim a credit on your home state return for taxes paid to North Carolina to avoid double taxation.

What is the difference between North Carolina's flat tax rate and federal tax brackets?

North Carolina charges everyone the same 4.99% rate on taxable income, so a person earning $30,000 pays the same percentage as someone earning $300,000. Federal taxes use brackets where your rate increases as your income rises. This means your federal tax burden changes with income, but your state burden does not.

Can I deduct federal income taxes from my North Carolina state return?

No. North Carolina does not allow a deduction for federal income taxes paid. You can deduct state and local property taxes up to $20,000 on your federal return, but this does not reduce your North Carolina state tax.

What happens if I do not file a North Carolina return when I owe tax?

The state charges penalties and interest on unpaid taxes. The penalty is typically 5% of the unpaid tax per month, up to 25%, plus interest that compounds daily. If you owe a significant amount, the state may place a lien on your property or garnish your wages to collect.

Are retirement distributions from a 401(k) or IRA taxed by North Carolina?

Yes. Distributions from traditional IRAs and 401(k)s are taxed as ordinary income at the 4.99% rate. Roth IRA distributions are not taxed if the account meets certain age and holding-period requirements. Some retirement income sources, like military pensions and certain government pensions, receive partial exemptions.
