NC's rate phase-down
Legislation passed in 2021 stepped NC's flat rate from 5.25% → 4.99% (2022) → 4.75% (2023) → 4.5% (2024) → 4.25% (2026) → 3.99% (2027). Plan multi-year tax decisions accordingly.
Research Triangle salary arbitrage
Raleigh/Durham tech salaries run roughly 15–20% below Bay Area for senior roles, but NC's 4.25% flat tax + lower COL nets a typical 25–30% improvement in disposable income at the $200K base level.
NC standard deduction is generous
$12,750 single / $25,500 joint matches federal — many states cap state deductions much lower. Combined with the flat rate, NC's tax code is genuinely simple.
