Below is the 2026 tax withholding and April shortfall breakdown across sample Nvidia engineering levels for a Single filer in North Carolina (at a reference share price of $135/share via E*TRADE by Morgan Stanley / Charles Schwab):

North Carolina Supplemental Tax Regulations for Nvidia RSUs

North Carolina applies a flat individual income tax rate (scheduled at 4.25%–4.50% under current statutory reductions, with supplemental withholding set at 4.50% / statutory rate + 0.1%). Because North Carolina utilizes a flat tax structure, employer sell-to-cover withholding covers virtually 100% of your state RSU tax bill—meaning your April shortfall is driven almost entirely by the 22% vs. 35%/37% federal gap.

North Carolina Bracket Architecture: Flat state income tax structure (~4.25%–4.50%) with no municipal or local wage taxes.

North Carolina Safe Harbor & Estimated Tax Vouchers (NCDOR Form NC-40 (Individual Estimated Income Tax))

Form NC-40 estimated tax payments are required if you expect to owe $1,000 or more in North Carolina tax after withholding (safe harbor: 90% of current-year or 100% of prior-year NC tax).

Multi-State Relocation & Nonresident Sourcing Rules in North Carolina

North Carolina Department of Revenue taxes nonresidents on RSU income according to the ratio of North Carolina workdays to total workdays from grant date through vest date.

Employer Stock Plan Specifics: Nvidia (E*TRADE by Morgan Stanley / Charles Schwab)

Due to Nvidia’s multi-year stock appreciation and split-adjusted share counts, unvested initial grants and annual focal refreshers routinely generate large quarterly vest valuations. Under IRC § 3402(g), your brokerage withholds only 22% federal tax on the first $1,000,000 of supplemental wages each calendar year, before jumping to 37% on every dollar above $1,000,000. That leaves the first $1,000,000 of NVDA vests underwithheld by up to $150,000 federally.

Withholding Election Guidance: Nvidia employees should review their supplemental withholding elections in E*TRADE / Schwab or via Nvidia Payroll prior to the March, June, September, and December vest dates. Even if your annual vests exceed $1,000,000 and trigger the mandatory 37% tier on the excess, the initial $1,000,000 tranche still creates an ~13%–15% federal gap (and a ~3.1% California gap above the 10.23% flat rate) unless you make quarterly estimated payments.
