North Carolina filing notes
Do not mix filing season with tax year: 2025 returns due April 15, 2026 use 4.25%, while tax year 2026 uses 3.99%. Social Security is fully exempt. NC does not allow the same standard deduction amount as the federal return, so use the NC standard deduction or NC itemized deductions rules separately.
Common mistakes: Not amortizing costs over $5,000; Including ongoing expenses.
