Three taxes on side income

Federal self-employment tax: 12.4% Social Security (on combined wages and self-employment earnings up to $184,500 in 2026) plus 2.9% Medicare, figured on 92.35% of your net profit. Half of it is deductible (IRS: self-employment tax; SSA 2026 fact sheet).
Federal income tax at your regular bracket, after business expenses.
North Carolina income tax at a flat 3.99% for 2026. NC starts from your federal adjusted gross income, so business expenses and the deductible half of self-employment tax lower your NC tax too (NCDOR: tax rate schedules).

A quick example

Say you net $10,000 from DoorDash or Etsy on top of a W-2 job that already uses up your NC standard deduction.

Self-employment tax: $10,000 × 92.35% × 15.3% ≈ $1,413
NC income tax: ($10,000 − $706, the deductible half) × 3.99% ≈ $371
Federal income tax: depends on your bracket and deductions, so add it on top.

Rounded illustration only. Your numbers depend on your full return.

Paying as you go: NC-40 and withholding

NC estimated tax: if the NC tax due on your return, after NC withholding and credits, is expected to be $1,000 or more, NCDOR expects estimated payments with Form NC-40 or online (NCDOR: estimated income tax).
2026 due dates (calendar year): April 15, June 15 and September 15, 2026, and January 15, 2027. You can skip the January payment if you file your D-400 by January 31 and pay the balance in full.
Have a day job? Instead of NC-40 payments, you can ask for extra NC withholding on Form NC-4. Our NC paycheck calculator shows the effect.
Federal estimates work the same way, with Form 1040-ES (IRS: estimated taxes).

Gig drivers and delivery

Expect a 1099-NEC or 1099-K from each app, but report all of your income even if a form never arrives.
Your phone, the business share of your data plan, insulated bags and parking (not tickets) are common deductions.

Online sellers: NC sales tax basics

Selling on Etsy, eBay, Amazon or Poshmark: a marketplace facilitator that's engaged in business in NC collects and sends in the sales tax on sales through its platform, so you generally don't collect it on those sales (NCDOR: marketplace FAQ).
Selling directly (your own website, in person, at markets or by invoice): if you're based in NC, register with NCDOR (no fee) and collect the state 4.75% rate plus the local rate where the sale is sourced, such as 7% total in New Hanover County or 6.75% in Brunswick (NCDOR: business registration; NCDOR: county rates).
Out-of-state sellers must collect NC sales tax once their NC-sourced gross sales top $100,000 in the current or prior calendar year; the old 200-transaction test was repealed July 1, 2024 (NCDOR: Directive 24-1).
Returns are filed on Form E-500, monthly or quarterly depending on how much tax you collect (NCDOR: guidance for newly registered taxpayers).

Frequently asked questions

What is the North Carolina income tax rate for 2026?

A flat 3.99% of North Carolina taxable income for tax years beginning in 2026, set by Session Law 2023-134. It applies to side income the same way it applies to wages.

Do I have to make NC estimated tax payments on side income?

If the NC tax due on your return, after withholding and credits, is expected to be $1,000 or more, NCDOR expects quarterly estimated payments with Form NC-40. Raising your NC-4 withholding at a day job is another way to cover it.

When are North Carolina estimated taxes due for 2026?

For calendar-year filers: April 15, June 15 and September 15, 2026, and January 15, 2027. You can skip the January payment if you file your 2026 D-400 by January 31, 2027 and pay the balance in full.

Do Etsy and eBay sellers in North Carolina collect sales tax?

On sales through a marketplace facilitator engaged in business in NC, the marketplace collects and sends in the sales tax. On direct sales, such as your own website or in-person sales, an NC-based seller registers with NCDOR and collects the state rate plus the local rate.

Does self-employment tax apply in North Carolina?

Yes. Self-employment tax is federal, so it applies the same in every state: 15.3% on 92.35% of net profit (12.4% Social Security up to the $184,500 wage base for 2026, plus 2.9% Medicare). North Carolina's 3.99% income tax is separate.
