North Carolina state income tax — ITIN filer guide

North Carolina taxes income at a flat 3.99% (tax year 2026), administered by the North Carolina Department of Revenue (NCDOR). This guide covers who must file, how filing with an ITIN works, whether the state EITC applies to you, and when refunds arrive.

FLAT rate: 3.99%

  • State return form: Form D-400 (Individual Income Tax Return)
  • Deadline (tax year 2026): April 15, 2027
  • Who must file: Must file if gross income exceeds the NC standard deduction for your filing status (exact TY2026 amounts on ncdor.gov — not captured this session).
  • State sales tax: 4.75%
  • Scheduled change: Statutory phase-down: 3.99% (2026) -> 3.49% (2027-2029) -> 3.14% (2030-2032) -> 2.99% (2033-2034) under the May 2026 budget deal, with further trigger-based cuts possible after 2034.

North Carolina refund timing

  • E-filed returns: NCDOR publishes no fixed timeframe; says e-filed returns with direct deposit process fastest.
  • Paper returns: NCDOR: 'It may take longer to receive your refund check if you requested a paper check or filed a paper return.'
  • Check your North Carolina refund status

Filing with an ITIN

Your ITIN is fully accepted on the North Carolina state return — states accept the IRS-issued taxpayer number, the same one you use federally. The flow is always the same:

  1. Complete your federal return first (Form 1040 + ITIN)
  2. Transfer your federal figures to Form D-400 (Individual Income Tax Return)
  3. Apply state-specific deductions and credits
  4. E-file — NCDOR ’eFile for Free’ program via approved vendor offers (income/eligibility limits) — current vendor list not re-verified this session.
  5. Or visit a VITA site for free in-person preparation

North Carolina state EITC — do ITIN filers qualify?

The federal EITC requires valid SSNs for you, your spouse, and qualifying children — ITIN filers can never claim it. What varies is the STATE credit:

North Carolina has no state earned income tax credit (EITC). The federal EITC requires a valid SSN — ITIN filers cannot claim it in any state.

State child tax credit: No state CTC; NC instead allows a per-child deduction (not a credit) against taxable income.
