- North Carolina has a flat 3.99% state income tax for 2026. Flat rate: 4.5% for 2024, 4.25% for 2025, and 3.99% for tax years beginning after 2025 (S.L. 2023-134).
- State estimated tax

Same dates as federal (April 15, June 15, September 15, January 15). The January installment is not required if you file and pay in full by January 31. Farmers and commercial fishermen (at least two-thirds of income) may pay by January 15, or skip estimates by filing and paying by March 1. Form NC-40.

Federal rules for 2026
W-2 or 1099 changes everything
On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.
Tools and equipment
Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.
Overtime deduction for W-2 workers
Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
A worked example
| Self-employment tax | $9,891 |
|---|---|
| Self-employment tax per quarter | $2,473 |
| SEP IRA maximum | $13,011 |
| Solo 401(k) maximum | $37,511 |
