North Carolina's Income Tax Structure

North Carolina has a single state income tax rate that applies to all residents, regardless of income level. As of 2024, that rate is 4.99 percent. This is a flat tax, meaning everyone pays the same percentage of their taxable income to the state, unlike the federal system where rates increase as income rises.

The state also taxes certain types of income differently. Wages and salaries are taxed at the standard 4.99 percent rate. Interest, dividends, and capital gains follow the same rate. However, some income sources—like certain retirement distributions and Social Security benefits—may be partially or fully excluded from state taxation, depending on your age and total income.

North Carolina residents also pay federal income tax on top of state tax. The federal rate depends on your income bracket and filing status, and it is separate from what you owe the state. Your employer typically withholds both federal and state taxes from your paycheck.

Key Takeaways

  • North Carolina's state income tax rate is a flat 4.99 percent for all income levels as of 2024.
  • The flat rate applies to wages, salaries, interest, dividends, and capital gains.
  • Some retirement income and Social Security benefits may be excluded from state taxation depending on your age and total income.
  • You pay North Carolina state tax in addition to federal income tax, and both are usually withheld from your paycheck.
  • The state tax rate can change year to year, so checking the current rate before filing is important.

How the Flat Tax Rate Works in Practice

Because North Carolina uses a flat tax, your tax burden grows proportionally with your income. If you earn $30,000, you owe roughly $1,497 in state income tax. If you earn $60,000, you owe roughly $2,994. The percentage stays the same; only the dollar amount changes.

This differs from the federal system, where higher earners move into higher tax brackets. Federal tax brackets mean that as your income increases, only the income in the higher bracket gets taxed at the higher rate. North Carolina's flat structure is simpler to calculate but does not reduce the tax burden for higher earners the way bracket-based systems can.

Income Sources Taxed at the Standard Rate

Most income you receive is subject to the 4.99 percent state tax. This includes W-2 wages from an employer, self-employment income, interest earned on savings accounts and bonds, and dividends from stocks or mutual funds. If you sell an asset at a profit, that capital gain is also taxed at the standard rate.

Rental income, income from a side business, and income from freelance work all fall under the standard rate as well. If you receive a bonus, commission, or overtime pay, that counts as regular income and is taxed the same way.

Retirement Income and Special Exclusions

North Carolina offers partial tax breaks for certain types of retirement income. If you are 59½ or older, you can exclude up to $35,000 per year of retirement income from state taxation. This includes distributions from IRAs, 401(k)s, pensions, and annuities. The exclusion applies only to you—if you are married filing jointly, your spouse can also exclude up to $35,000 of their own retirement income.

Social Security benefits are not taxed by North Carolina, regardless of your age or income level. This is one of the few income sources completely exempt from state tax. However, if you receive other income alongside Social Security, that other income is still taxed normally.

Military pensions and certain other government pensions may also may have access to for partial or full exclusion, depending on when you retired and the type of pension. Check with the North Carolina Department of Revenue if you receive a government pension to confirm your exclusion amount.

How Withholding Works on Your Paycheck

Your employer withholds North Carolina state income tax from each paycheck based on the W-4 form you complete when hired. The withholding is calculated to estimate what you will owe at the end of the year. If too much is withheld, you receive a refund when you file your return. If too little is withheld, you owe money.

You can adjust your withholding at any time by submitting a new W-4 to your employer. This is useful if your life circumstances change—for example, if you get married, have a child, or take on a second job. Adjusting your withholding can help you avoid a large refund or a large bill at tax time.

If you are self-employed, you do not have an employer to withhold taxes. Instead, you are responsible for paying estimated taxes quarterly to both the federal government and North Carolina. These quarterly payments help you stay current with your tax obligations throughout the year.

Changes to the Tax Rate Over Time

North Carolina's income tax rate has changed several times in recent years. In 2021, the rate was 4.99 percent. The state legislature periodically adjusts the rate, so it is worth checking the current rate before you file your return or estimate your tax burden for the year.

The Department of Revenue website publishes the current tax rate and any changes that take effect during the year. If you are planning your finances or estimating taxes owed, using the most recent rate ensures your calculations are accurate.

Filing Your North Carolina State Return

Most North Carolina residents file their state return using Form NC-40, the individual income tax return. You file this return with the North Carolina Department of Revenue, separate from your federal return. The important date is typically April 15, the same as the federal important date, though you can request an extension.

You can file by mail, online through the Department of Revenue website, or through a tax preparation service. If you use tax software, it usually handles both your federal and state returns. Many people file their federal and state returns at the same time to simplify the process.

Frequently Asked Questions

Is North Carolina income tax higher or lower than other states?

North Carolina's 4.99 percent flat rate is moderate compared to other states. Some states have no income tax, while others have rates ranging from 5 to over 13 percent. The overall tax burden also depends on property taxes, sales taxes, and other state and local taxes, so comparing just the income tax rate does not tell the full story.

Do I have to pay North Carolina income tax if I work remotely for an out-of-state company?

If you live in North Carolina and work remotely, you owe North Carolina state income tax on your wages, even if your employer is based elsewhere. The state taxes income earned by residents, regardless of where the employer is located. Your employer may not withhold North Carolina tax if they are out of state, so you may need to make estimated quarterly payments or adjust your withholding.

What if I move to North Carolina during the year?

You owe North Carolina income tax only on income earned after you become a resident. If you moved mid-year, you file a part-year resident return and report only the income you earned while living in the state. You will also file a return in your previous state for the income earned there.

Can I deduct state income tax on my federal return?

You can deduct state and local taxes (SALT) on your federal return, but only if you itemize deductions rather than take the standard deduction. The total SALT deduction is capped at $10,000 per year. Many people find the standard deduction is larger, so they do not benefit from itemizing.

Where do I find my North Carolina tax forms and instructions?

The North Carolina Department of Revenue website publishes all state tax forms, instructions, and current tax rates. You can read forms directly or order them by mail. The website also has a tax calculator to estimate your state tax liability and answers to common tax questions.
