How to Pay Your North Carolina State Income Tax
Where and how to pay North Carolina state income tax
North Carolina accepts state income tax payments through three main channels: online through the Department of Revenue website, by mail, or through an authorized payment processor. The online method is fastest and gives you immediate confirmation. If you file a return, you can pay when you file, or make a separate payment anytime before the deadline. Payments made online typically post within one business day.
The state also allows payments by phone through an authorized third-party processor, though this method charges a convenience fee. Mail payments take longer to process—typically 7 to 10 business days—so if you are close to a deadline, online or phone payment is safer. The mailing address for checks is on the Department of Revenue website and changes based on what type of payment you are sending.
Key Takeaways
- Online payment through the North Carolina Department of Revenue website is free and posts within one business day.
- The state income tax deadline is the same as the federal deadline—April 15 in most years, or the next business day if April 15 falls on a weekend or holiday.
- If you owe tax when you file, you can pay at the same time you submit your return, or pay separately before the deadline.
- Payments by phone or through a third-party processor charge a convenience fee; paying online through the state website does not.
- If you cannot pay by the deadline, you can still file your return on time to reduce penalties, and then pay what you owe as soon as possible.
Paying online through the North Carolina Department of Revenue
The North Carolina Department of Revenue website has a payment portal where you can pay by bank account (ACH transfer) or credit or debit card. To use it, you will need your Social Security number or federal employer identification number, the tax year you are paying for, and the amount owed. The portal generates a confirmation number immediately after payment, which you should save for your records.
ACH payments (direct from your bank account) are free and typically post within one business day. Credit and debit card payments are also accepted but are processed through a third-party payment processor that charges a fee—usually between 2 and 3 percent of the payment amount. The processor discloses the exact fee before you complete the transaction, so you know the total cost before you commit.
Paying by mail or check
If you prefer to mail a check, write it to the North Carolina Department of Revenue and include your Social Security number on the check itself. The mailing address depends on whether you are paying income tax, sales tax, or another type of tax—the Department of Revenue website lists the correct address for each. Mail your payment so it arrives by the tax deadline; the postmark date is what counts, not the date it is received.
Mailed payments take 7 to 10 business days to post to your account after they arrive at the Department of Revenue office. If you are paying close to the deadline, this delay means your payment may not show as received until after the deadline has passed. For this reason, the state recommends online payment if you are near the deadline. Keep a copy of your cancelled check or a photo of the front and back as proof of payment.
Payment deadlines and what happens if you miss them
North Carolina state income tax is due on the same date as federal income tax: April 15 in most years. If April 15 falls on a Saturday, Sunday, or federal holiday, the deadline moves to the next business day. The state also observes Emancipation Day (June 19) as a holiday, which can shift deadlines in some years—check the Department of Revenue website for the exact date each year.
If you do not pay by the deadline, the state charges interest on the unpaid balance starting the day after the deadline. The interest rate is set quarterly and varies. The state also imposes penalties: a failure-to-pay penalty of 0.5 percent per month (up to 25 percent total) if you do not pay by the deadline, and a separate failure-to-file penalty if you do not file a return. Filing your return on time, even if you cannot pay, reduces the failure-to-file penalty and gives you time to arrange payment.
Estimated tax payments and quarterly deadlines
If you are self-employed, own a business, or have income that is not subject to withholding, North Carolina requires you to make estimated tax payments four times a year. These are due on April 15, June 15, September 15, and January 15 of the following year. You can make estimated payments through the same online portal used for regular tax payments, or by mail using the same process.
Underpayment of estimated tax can result in interest and penalties, even if you end up paying the full amount owed when you file your annual return. The Department of Revenue website has a worksheet to help you calculate how much to pay each quarter based on your expected income. If your income changes during the year, you can adjust your remaining quarterly payments.
What to do if you cannot pay in full by the deadline
If you owe tax but cannot pay the full amount by April 15, file your return anyway. Filing on time stops the failure-to-file penalty and gives you more time to pay. You will still owe interest on the unpaid balance, but the penalty is smaller if you file before the deadline than if you file late.
North Carolina does not publish a formal payment plan program on its website the way some states do, but you can contact the Department of Revenue to discuss options. The state may allow you to pay in installments, though interest continues to accrue on the unpaid balance. Paying even a partial amount before the deadline is better than paying nothing, because it reduces the total interest you will owe. Contact the Department of Revenue's taxpayer assistance line for guidance on your specific situation.
Frequently Asked Questions
Can I pay my North Carolina state tax through my bank's bill pay system?
Some banks allow you to pay the Department of Revenue through their bill pay system, but this is not the fastest or most reliable method. The state recommends using the Department of Revenue's online payment portal instead, which posts within one business day. If you use your bank's bill pay, allow extra time and confirm the payment has posted before the deadline.
What if I filed my federal return but have not filed my North Carolina return yet?
North Carolina has its own separate filing deadline, which is the same date as the federal deadline. You must file a North Carolina return if you owe state tax, even if you do not owe federal tax. File and pay as soon as possible to avoid penalties and interest.
Do I need to pay if I had taxes withheld from my paycheck?
Not necessarily. If your employer withheld enough tax throughout the year, you may not owe anything when you file. You will know after you complete your return. If you overpaid, you can receive a refund instead of making a payment.
What happens if I pay late but before the Department of Revenue contacts me?
Interest and penalties begin accruing the day after the deadline, regardless of whether the state has contacted you. Paying late does not erase the interest and penalties already owed, but it stops them from continuing to grow. Pay as soon as you can.
Can I pay someone else's North Carolina state tax?
Yes. You can pay another person's tax if you have their Social Security number and the amount they owe. Use the Department of Revenue's online portal and enter their information. The payment will be credited to their account.
