North Carolina Supplemental Tax Regulations for Google (Alphabet) 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.

Employer Stock Plan Specifics: Google (Alphabet) (Charles Schwab / Morgan Stanley)

Google Stock Units (GSUs) follow a frontloaded 33% / 33% / 22% / 12% four-year schedule, vesting monthly on the 25th. While monthly vesting smooths out stock price volatility compared to quarterly cliffs, it creates a silent, compounding tax deficit: every single month, your GSU release is taxed at the 22% flat federal supplemental rate, plus your annual January performance bonus is also withheld at 22%. By December, L5+ Googlers routinely accumulate 12 consecutive months of 10%–15% federal underwithholding.

Withholding Election Guidance: Google allows U.S. employees to adjust their federal supplemental tax withholding rate directly inside Charles Schwab Equity Award Center (under Account Settings -> Tax Withholding Elections). Because GSUs vest monthly, updating your rate to 32%, 35%, or 37% early in Q1 applies to all remaining monthly vests for the calendar year—eliminating the need to mail manual quarterly Form 1040-ES checks.
