Being self-employed in North Carolina offers flexibility, independence, and the ability to control how and when you earn. But it also comes with added responsibility especially when it comes to taxes. Freelancers, independent contractors, gig workers, consultants, and small business owners must handle their own federal and state tax obligations without employer withholding.
If you earn income on your own in the state, understanding North Carolina self-employed taxes for 2025–2026 is essential to staying compliant, avoiding penalties, and reducing your overall tax burden. From federal self-employment tax to North Carolina’s flat income tax, quarterly estimated payments, deductions, and sales tax requirements, this guide explains everything step by step in plain English.
Who Is Considered Self-Employed in North Carolina?
You are considered self-employed in North Carolina if you earn income outside of a traditional employer-employee relationship. This includes individuals who:
- Work as freelancers or independent contractors (1099 workers)
- Operate as sole proprietors or single-member LLC owners
- Earn gig income from rideshare, delivery, or task-based platforms
- Run online businesses or provide consulting services
- Have side hustles alongside a W-2 job
If your net self-employment income is $400 or more, federal law requires you to file a tax return and pay self-employment tax.
How Self-Employed Taxes Work in North Carolina
Self-employed individuals in North Carolina are responsible for paying:
- Federal taxes, including self-employment tax and federal income tax
- North Carolina state income tax
Unlike employees, no taxes are automatically withheld from your earnings. You must calculate and pay these taxes yourself throughout the year.
Federal Self-Employment Tax Explained
Federal self-employment tax covers your Social Security and Medicare contributions. When you work for yourself, you pay both the employee and employer portions.
For the 2025–2026 tax years, the rates are:
- Social Security tax: 12.4% on net earnings up to the annual limit
- Medicare tax: 2.9% on all net earnings
- Additional Medicare tax: 0.9% if income exceeds
- $200,000 for single filers
- $250,000 for married filing jointly
The standard combined self-employment tax rate is 15.3%.
A key benefit for self-employed taxpayers is that 50% of your self-employment tax is deductible, which reduces your adjusted gross income and lowers your federal income tax bill.
North Carolina State Income Tax for Self-Employed Workers
North Carolina uses a flat income tax system, which simplifies state tax calculations.
For 2025–2026:
- North Carolina state income tax rate: 4.75%
This flat rate applies to your taxable income after deductions and adjustments. North Carolina does not impose local or county income taxes, so you only pay state-level income tax.
Do Self-Employed Individuals in North Carolina Need to Pay Quarterly Estimated Taxes?
Yes. If you expect to owe $1,000 or more in total taxes for the year, you are required to make quarterly estimated tax payments.
Estimated taxes apply to:
- Federal self-employment and income taxes
- North Carolina state income tax
Quarterly Estimated Tax Deadlines
Estimated tax payments are generally due on:
- April 15
- June 15
- September 15
- January 15 (of the following year)
Missing a payment or paying late can result in penalties and interest, even if you pay your full balance when filing your return.
How to Calculate Quarterly Estimated Taxes
Quarterly estimated taxes are advance payments made throughout the year to cover taxes that aren’t withheld from your income. For self-employed individuals in North Carolina, these payments usually include federal self-employment tax, federal income tax, and state income tax. Calculating them correctly helps you avoid penalties and large tax bills later.
Estimate Your Total Annual Business Income
Start by estimating how much your business will earn for the entire year before expenses. This includes all income from freelancing, consulting, gig work, or business sales. If your income fluctuates, use what you’ve earned so far and make a realistic projection based on current contracts, clients, or seasonal trends.
Identify Business Deductions and Expenses
Next, estimate your deductible business expenses. Common expenses include supplies, software, advertising, insurance, professional fees, home office costs, and business mileage. Keeping track of these throughout the year gives you a clearer picture of how much income is actually taxable.

Calculate Net Self-Employment Income
Subtract your estimated business expenses from your total projected income. The result is your net self-employment income. This number is critical because it’s used to calculate both self-employment tax and income tax.
Calculate Federal Self-Employment Tax
Federal self-employment tax covers Social Security and Medicare. It’s generally calculated at 15.3% of your net self-employment income. Even if you don’t expect to owe much in federal income tax, self-employment tax often represents a significant portion of what you owe each year.
Estimate Federal Income Tax
After accounting for deductions and adjustments, estimate your federal income tax based on your filing status and income level. Many self-employed individuals look at their prior year’s federal tax return to see how much income tax they paid and then adjust that amount based on whether income is expected to increase or decrease.
Add North Carolina State Income Tax
North Carolina uses a flat state income tax rate, which makes estimating state taxes more straightforward. Apply the state rate to your taxable income to estimate how much you’ll owe to North Carolina. Be sure to include this amount in your total estimated tax calculation.
Determine Your Total Annual Estimated Tax
Once you’ve calculated federal self-employment tax, federal income tax, and North Carolina state income tax, add them together. This total represents your estimated tax liability for the year.
Divide Into Quarterly Payments
Divide your total estimated annual tax by four to determine your quarterly payment amount. These payments are typically due in April, June, September, and January of the following year. If your income changes during the year, you can recalculate and adjust future payments to better match what you actually owe.
Use Last Year’s Return as a Reference
Many self-employed workers use their previous year’s tax return as a starting point because it provides a realistic baseline. This method works well if your income is relatively stable. If you experience significant changes in income, reviewing and updating your estimates midyear can help prevent underpayment penalties.
Staying proactive and revisiting your numbers throughout the year makes quarterly estimated taxes more manageable and helps you stay compliant without unnecessary stress.
