North Carolina 1099 Tax Calculator (2026)
North Carolina taxes income at a flat 3.99% for 2026— down from 4.50%, and falling again next year — with no brackets and no local income tax anywhere in the state. So your bill is three layers and only three: federal self-employment tax, federal income tax, and one state rate. The calculator below is already set to $55,000 of 1099 income, filing single, state = NC. Change any field to match your own numbers.

Want to tweak this scenario in the full stacking calculator (including W-2 wages)? Open it prefilled for North Carolina. One warning about its North Carolina line: the widget applies 3.99% to federal taxable income, which gives $989. The real D-400 charges the same rate on a base built its own way, so the figure to plan against is the $1,531 above — the section after next shows exactly where the gap comes from.
What this result means in North Carolina
The federal half comes first, and it is identical in every state. Self-employment tax applies to 92.35% of net earnings — $50,793 × 15.3% = $7,771, being $6,298 of Social Security and $1,473 of Medicare. Half of that, $3,886, comes back off your income. After the $16,100 federal standard deduction and the 20% QBI deduction (worth $10,223 here), federal income tax on what is left lands near $2,727.
North Carolina is the third layer and, as state taxes go, an unusually plain one. One rate, no brackets, no county or city surtax, and a single across-the-board subtraction: the $12,750state standard deduction. Your D-400 starts from federal adjusted gross income — $51,114here, being profit less the deductible half of your self-employment tax — takes off that $12,750, and charges 3.99% of the $38,364 left. That comes to $1,531.
All three together come to $12,029, an effective rate of 21.9% of gross — and that is the whole bill, because no North Carolina city or county levies an income tax. The state layer is worth 13% of it. Put another way, of every dollar of tax you send anywhere, about 87 cents goes to Washington.
Figures assume no business expenses, no credits, and the standard deduction on both returns. Every deductible expense you track cuts all three layers at once, because it shrinks the net profit they all start from; run yours through the deduction estimator.
The rate on this page is not the rate you paid last year
This is the part most North Carolina tax advice gets wrong, and it is worth checking before you copy a number off anywhere else. North Carolina’s flat rate has fallen every January since 2022 under a schedule written into S.L. 2023-134. Anything still quoting 4.50% is describing 2024; 4.25% was 2025. For 2026 it is 3.99%.
Two more step-downs are already in the statute, each conditional on General Fund net revenue clearing a trigger amount rather than on a fresh vote. Revenue cleared the trigger for 2027, so 3.49% is set; 2028’s step to 2.99% depends on the next trigger. The base below never changes — only the rate does — so the same $55,000 of profit is easy to price in each year.
| Tax year | Flat rate | NC tax on $55,000 | Status |
|---|---|---|---|
| 2022 | 4.99% | $1,914 | Past |
| 2023 | 4.75% | $1,822 | Past |
| 2024 | 4.50% | $1,726 | Past |
| 2025 | 4.25% | $1,630 | Past |
| 2026 | 3.99% | $1,531 | Current — 2026 |
| 2027 | 3.49% | $1,339 | Scheduled, revenue trigger cleared |
| 2028 | 2.99% | $1,147 | Scheduled, trigger pending |
Read the third column as the practical consequence: a freelancer at this profit is paying $384 less to Raleigh than in 2022, and stands to pay another $192less in 2027. It also means the standard advice to “just pay what you paid last year” systematically overshoots here — more on that in the quarterly section below.
What the 3.99% is actually charged on
The rate is the easy half. The base is where North Carolina and the IRS part company — the D-400 starts from federal adjusted gross income, not federal taxable income, and then applies its own deduction instead of the federal ones.
| Step | Federal | North Carolina |
|---|---|---|
| Schedule C net profit | $55,000 | $55,000 |
| Half of self-employment tax | −$3,886 | −$3,886 |
| Adjusted gross income | $51,114 | $51,114 (D-400 starts here) |
| Standard deduction | −$16,100 | −$12,750 |
| QBI deduction | −$10,223 | no equivalent |
| Income actually taxed | $24,791 | $38,364 |
| Income tax charged on it | $2,727 | $1,531 |
Two lines do all the work. The half of self-employment tax doescarry over, because it is an above-the-line adjustment that is already inside AGI before North Carolina ever sees the number — and the same is true of every other above-the-line deduction a freelancer has, including SEP-IRA and solo 401(k) contributions and HSA contributions. Each $1,000 of them is worth $39.90 of North Carolina tax on top of the federal saving.
The QBI deduction does not, because it sits below the AGI line and North Carolina has no §199A equivalent. That one omission is most of why North Carolina taxes $38,364 where the federal brackets see $24,791— about 1.5× as much income — even though its own standard deduction is only $3,350 smaller than the federal one.
Worth knowing about that $12,750: it is generous next to what most flat-tax states allow, but it is not indexed for inflation and has not moved since 2022, while the federal figure is reset every year. The rate cuts are doing the work; the deduction is quietly shrinking in real terms. The Schedule C calculator gets you to the profit all of this is charged on, and how self-employment tax works covers the 15.3% layer North Carolina neither charges nor forgives.
Your North Carolina quarterly tax schedule
Two sets of estimated payments, one calendar. The IRS wants Form 1040-ES whenever you expect to owe $1,000 or more at filing. North Carolina wants Form NC-40 once the tax due on your return, less state withholding and credits, is $1,000or more. Same dollar figure, but measured against the much smaller state bill — so it bites far later. On this page’s assumptions the North Carolina liability alone does not reach $1,000 until around $40,500 of profit, well after the federal trigger. Both use the same four dates.
| Quarter | Income earned | Due | Federal 1040-ES | NC-40 |
|---|---|---|---|---|
| Q1 | Jan 1 – Mar 31 | April 15, 2026 | $2,625 | $383 |
| Q2 | Apr 1 – May 31 | June 15, 2026 | $2,625 | $383 |
| Q3 | Jun 1 – Aug 31 | September 15, 2026 | $2,625 | $383 |
| Q4 | Sep 1 – Dec 31 | January 15, 2027 | $2,625 | $383 |
| Year | $10,498 | $1,531 | ||
The falling rate changes which safe harbor you should aim at. North Carolina charges no interest on an underpayment if your timely payments reach the smaller of 90% of this year’s tax or 100% of last year’s — and, unlike the IRS, it applies no 110% step-up for higher-income filers, so 100% means 100% at every income level. But because the rate dropped from 4.25% to 3.99% this January, last year’s tax on the same profit was $1,630 against this year’s $1,531. Setting your four NC-40 checks by last year’s number hands Raleigh $100interest-free until you file. In a state whose rate falls every January, the current-year route is usually the cheaper safe harbor — the opposite of the usual advice.
One more North Carolina convenience: if you file your return and pay the balance in full by January 31, you can skip the January 15 installment entirely. The quarterly tax calculator sizes the four federal checks from your own income, and the estimated tax payments guide covers what skipping one costs federally.
North Carolina 1099 taxes at other income levels
Same assumptions — filing single, no W-2 wages, no business expenses, no credits. The North Carolina column runs the real D-400 arithmetic: federal AGI less the $12,750 state standard deduction, at 3.99%.
| 1099 income | SE tax | Federal | North Carolina | NC % of gross | Total | Set aside |
|---|---|---|---|---|---|---|
| $25,000 | $3,532 | $249 | $418 | 1.67% | $4,199 | 17% |
| $40,000 | $5,652 | $1,389 | $975 | 2.44% | $8,015 | 20% |
| $55,000 | $7,771 | $2,727 | $1,531 | 2.78% | $12,029 | 22% |
| $75,000 | $10,597 | $4,511 | $2,272 | 3.03% | $17,381 | 23% |
| $100,000 | $14,130 | $7,527 | $3,199 | 3.20% | $24,856 | 25% |
The North Carolina column is flat in rate but not in share: the $12,750 standard deduction is worth the same dollars at every income, so it shields a large slice of a small profit and a thin one of a large profit. That is why the state takes 1.67% of gross at $25,000 but 3.20% at $100,000— a flat rate that still behaves slightly progressively. Turn whichever figure is yours into a per-invoice habit with how much to set aside.
No city or county in North Carolina taxes your 1099 income
Worth stating plainly, because it is the question freelancers moving to Charlotte or the Triangle ask first: North Carolina law reserves the income tax to the state. Counties and municipalities cannot levy one. Charlotte, Raleigh, Durham, Greensboro, Winston-Salem and Asheville all charge $0 on income — there is no local return, no local rate to look up by address, and no fourth estimated payment schedule to track. Local governments raise their money from property and sales taxes instead.
That is not a given elsewhere. In Pennsylvania a resident earned income tax reaches Schedule C net profits statewide, with nobody withholding it; New York City adds a resident tax on top of the state’s. In North Carolina the $1,531above really is the entire state-and-local income tax bill on this page’s profit.
What North Carolina does charge a freelancer beyond income tax: sales tax, if you sell taxable goods or certain services — see sales tax for freelancers — and, if you form an LLC, a $200 Secretary of State annual report fee every April 15, which is the steepest routine LLC upkeep among the states on this site. LLC vs sole proprietorship weighs that against what an LLC actually changes about your tax, which is nothing.
North Carolina 1099 Questions
How much tax does a 1099 contractor in North Carolina pay on $55,000?
Filing single with no business expenses, about $7,771 of self-employment tax, roughly $2,727 of federal income tax, and $1,531 of North Carolina income tax — around $12,029 in all, or 22% of gross. The North Carolina piece is 3.99% of $38,364: your profit less the deductible half of self-employment tax, less the $12,750 North Carolina standard deduction. No county or city adds anything on top.
Is North Carolina's income tax rate still 4.50%?
No — that was the 2024 rate, and it is the single most common stale figure in North Carolina tax advice. The rate has fallen every January under S.L. 2023-134: 4.75% for 2023, 4.50% for 2024, 4.25% for 2025, and 3.99% for 2026. On this page's profit the difference between the 2024 rate and today's is $196 a year. Two further step-downs are written into the statute and conditional on General Fund revenue clearing a trigger: 3.49% for 2027, which the revenue has already cleared, and 2.99% for 2028.
Does North Carolina charge its own self-employment tax?
No. The 15.3% self-employment tax is federal, funds Social Security and Medicare, and does not vary by state. North Carolina taxes the same Schedule C profit through its individual income tax instead, at one flat rate, on top of the federal bill rather than in place of any of it. North Carolina does give you partial credit for paying it, though, in a way some states do not: because the D-400 starts from federal adjusted gross income, the deduction for one-half of your self-employment tax — $3,886 here — is already inside the number North Carolina taxes.
Why is the North Carolina tax on this page higher than the site's calculator shows?
Different bases, same rate. The 50-state comparison table applies 3.99% to federal taxable income, which has already been cut by the $16,100 federal standard deduction and the 20% QBI deduction, giving $989. The real D-400 starts from federal AGI and subtracts North Carolina's own $12,750 standard deduction instead — there is no state QBI deduction — so it taxes $38,364 where the federal brackets see $24,791, about 1.5 times as much, and the bill is $1,531. Set money aside against the figure on this page.
Do North Carolina freelancers have to make state estimated payments?
Yes, once the state bill is big enough. Form NC-40 is required when the tax due on your return, less North Carolina withholding and credits, comes to $1,000 or more — the same dollar trigger the IRS uses, but measured against the much smaller state liability, so it bites much later. On this page's assumptions the North Carolina bill alone does not reach $1,000 until roughly $40,500 of profit. Payments are due April 15, June 15, September 15, and January 15; file the return and pay in full by January 31 and you can skip the January 15 installment.
Do I owe a city or county income tax anywhere in North Carolina?
No. North Carolina law reserves the income tax to the state — counties and municipalities cannot levy one. Charlotte, Raleigh, Durham, Greensboro, Winston-Salem and Asheville all charge freelancers $0 on income, and there is no local return to file and no local estimated payment to remember. That is a real simplification compared with states where a resident earned income tax or a city net profits tax lands on Schedule C income with nobody withholding it. North Carolina's local governments raise their money from property and sales taxes instead.
Does a SEP-IRA or solo 401(k) contribution cut my North Carolina tax?
Yes — fully, dollar for dollar. Self-employed retirement contributions are above-the-line deductions, so they come out of federal adjusted gross income, and AGI is exactly where the D-400 starts. On this page's profit, net earnings of $51,114 support a SEP-IRA contribution of up to $10,223, or up to $34,723 with a solo 401(k). Every $1,000 contributed takes $39.90 off the North Carolina bill on top of the federal saving. Health savings account contributions work the same way for the same reason.
Should a North Carolina freelancer itemize on the state return?
Usually not, and the North Carolina answer is independent of the federal one — you can itemize on one return and take the standard deduction on the other. North Carolina's itemized list is short and capped: qualified mortgage interest and real estate property taxes together are limited to $20,000, plus charitable contributions, medical and dental expenses, and repayment of claim of right income. There is no state deduction for state taxes paid and nothing resembling the full federal Schedule A. Against a $12,750 standard deduction, most freelancers without a substantial mortgage come out ahead taking it. Business expenses are a separate question entirely: they come off Schedule C profit before any of this, so you get them either way.
Does forming an LLC change what a North Carolina 1099 contractor pays?
Not the income tax. A single-member LLC is a disregarded entity federally and for North Carolina, so the profit still lands on your D-400 and is still taxed at 3.99%. What it adds is a fixed annual cost: every North Carolina LLC owes the Secretary of State an annual report with a $200 fee, due April 15 each year no matter which month the LLC was formed, with a late fee on top if you miss it. That is the highest routine LLC maintenance fee among the states this site covers, and it is worth weighing against the liability protection before filing.
