North Carolina Sales Tax Penalties and Interest
Checklist
What This Issue Means
Sales tax penalties and interest are additional charges assessed when businesses fail to file returns or pay collected sales and use tax on time. Penalties are fees imposed for late filing or late payment under NC law, while interest charges accrue on unpaid tax amounts from the due date until full payment is made. These charges increase the total amount owed and continue to grow until the underlying sales and use tax debt is resolved.
Why the State Issued This Assessment
The North Carolina Department of Revenue assesses penalties and interest to encourage timely compliance with sales tax filing and payment requirements under G.S. § 105-236. When businesses miss filing deadlines, submit tax payments late, or fail to pay the full amount owed, the state applies these charges under North Carolina General Statutes Chapter 105. The
Secretary of Revenue sets the interest rate at 7% per year, through December 31, 2025.
What Happens If This Is Ignored
Ignoring penalties and interest notices causes the total amount owed to increase as interest charges continue to accrue daily on the unpaid balance. The state may escalate collection efforts by sending additional notices, placing tax liens on business assets, or pursuing legal collection actions. Delinquent accounts can eventually lead to serious consequences, including a Collection Assistance Fee of 20% on amounts unpaid for 60 days after becoming collectible, as well as potential impacts on business operations.
Step-by-Step Checklist
Step 1: Review All Related Documents
Locate the penalties and interest notice from the North Carolina Department of Revenue and identify the notice date, tax period covered, and total amount assessed. Gather all prior sales tax notices, tax payment confirmations, and correspondence to create a complete record of your account history and filing period details.
Step 2: Verify the Assessment Details
Confirm that the notice was issued to your current business address and that the tax account number matches your Certificate of Registration records. Check that the tax period dates listed correspond to periods when your business operated and verify the business identification information is accurate on the NCDOR website.
Step 3: Review Your Filing History
Locate copies of all Form E-500 sales and use tax returns filed for the period in question and gather payment receipts or bank statements showing tax payments made to the state.
Document the date each return was filed based on your filing frequency and each payment was submitted, noting whether submissions were timely or late.
Step 4: Understand the Calculation
Identify the original sales and use tax amount owed separately from penalties and interest on the notice you received from the Department of Revenue. The late filing penalty is 5% of the net tax due per month, up to a maximum of 25%, while the late-payment penalty is currently 5% of the unpaid tax.
Step 5: Determine Late Filing or Payment Dates
Compare the return due date to your actual filing date, and the payment due date to your actual payment date, to determine how many days late each submission was. Document whether returns were filed, UT tax payments were late, or whether no returns were filed at all for the covered filing period.
Step 6: Prepare Supporting Documentation
Document any business circumstances that led to late filing or payment, such as illness, staffing changes, accounting errors, natural disasters, or impacts from the COVID-19 outbreak that affected your operations. Gather evidence supporting reasonable cause claims, noting whether this was your first late filing or payment for this business, and documenting any pattern of prior timely compliance.
Step 7: Review Penalty Relief Options
Visit the NCDOR website to review the three types of penalty waivers available under the official
Penalty Waiver Policy for waiving penalties effective July 8, 2025. Good Compliance: waivers allow one waiver per tax type every three years; Automatic waivers apply for death, serious illness, or natural disaster within three months; and Special Circumstances waivers provide tax relief in limited situations.
Step 8: Contact the Department of Revenue
Call the Department of Revenue Business Tax Section to ask questions about the notice and request written confirmation of any information provided by phone. Ask the representative to
explain how the penalty charge and interest rate were calculated and inquire about payment arrangements or tax relief options available for your specific situation.
Step 9: Submit a Penalty Waiver Request
If you qualify for penalty relief, complete Form NC-5500 Request to Waive Penalties or write a letter containing the same information requested on the form. Include all supporting documentation, reference the specific notice number and tax period, and submit the request to the address listed on the form within applicable statute of limitations timeframes.
Step 10: Address the Underlying Tax Debt
Determine the exact amount of original sales and use taxes owed, without penalties or interest, and decide whether to pay in full or arrange a payment plan. Contact the Department of
Revenue to inquire about installment agreement options, understanding that the annual interest charge continues to accrue on past due balances throughout the payment period until the debt is paid.
Step 11: Monitor for Follow-Up Communications
Watch for responses to any penalty waiver request, and check for additional notices or account statements after making tax payments to verify proper crediting. Document the date you receive any follow-up communication and verify that payments are applied correctly to your account to prevent further collection action on delinquent accounts.
