Estimates use 2026 US federal figures (IRS Rev. Proc. 2025-32): self-employment tax of 15.3% (12.4% Social Security up to the $184,500 wage base + 2.9% Medicare) plus federal income tax on your net profit after the standard deduction. State and local taxes are only included if you set a state rate above. Simplified estimate for planning only — not tax advice.
Guide: Self-employment tax in North Carolina — one flat rate
North Carolina keeps it simple: a single flat income tax rate on top of your federal bill. For 2026 the rate is 3.99% (2025: 4.25%; 2024: 4.50%), with further trigger-based reductions possible from 2027. The 2026 standard deduction is $12,750 for single filers (also married filing separately), $25,500 joint, and $19,125 head of household — and $0 if you are not eligible for the federal standard deduction. There is no local income tax, and no extra state self-employment tax: the professional privilege licence was repealed July 1, 2024, except for loan agencies, pawnbrokers, and check cashers.
The federal layer is the same in every state. Self-employment tax is 15.3% (12.4% Social Security + 2.9% Medicare) on 92.35% of your net profit, and it applies once your net earnings reach $400. The Social Security wage base is $184,500 for 2026; Medicare is uncapped. The deduction for half of your SE tax lowers your income tax only — it does not lower your net earnings or your SE tax.
Because the rate is flat, the North Carolina math is just one subtraction and one multiplication: subtract the standard deduction, then apply 3.99%. There are no brackets to climb and no local rate to stack on top, which makes North Carolina one of the easiest states to estimate — and one where the federal bill is usually the bigger number.
Worked example. Take a single freelancer with $60,000 of net profit. Federal SE tax is $60,000 x 92.35% = $55,410, x 15.3% = $8,477.73. North Carolina tax is ($60,000 - $12,750) x 3.99% = $47,250 x 3.99% = $1,885.28. Your total state-plus-SE bill on that profit is $10,363.01, before federal income tax.
North Carolina estimated payments use Form NC-40, due April 15, June 15, and September 15, and January 15. Estimates are required if the tax due after withholding and credits is $1,000 or more.
