New York Supplemental Tax Regulations for Google (Alphabet) RSUs

New York State Department of Taxation and Finance prescribes an 11.70% statutory supplemental withholding rate (plus up to 4.25% for New York City residents if local withholding is configured). For NYC tech workers, combined NYS marginal rates (6.85% to 10.90%) and NYC resident income tax (3.876%) create a combined marginal burden of 10.73% to 14.78%, frequently resulting in municipal and state shortfalls.

New York Bracket Architecture: Progressive state brackets up to 10.9% (6.85% for $215,400–$1,077,550; 9.65% up to $5M), plus 3.078%–3.876% New York City local resident income tax.

New York Safe Harbor & Estimated Tax Vouchers (NYS Form IT-2105 (Estimated Income Tax Payment Voucher))

Requires quarterly Form IT-2105 vouchers if New York tax owed after withholding exceeds $300. High-income filers (NY AGI > $150,000) must remit 110% of prior-year NY/NYC tax or 90% of current-year liability.

Multi-State Relocation & Nonresident Sourcing Rules in New York

Under 20 NYCRR § 132.24 and NYS Technical Memorandum TSB-M-07(7)I, New York allocates RSU income for nonresidents and part-year residents based on the ratio of New York workdays to total workdays during the "grant-to-vest" measurement period, strictly enforcing the "convenience of the employer" rule for remote workers assigned to a Manhattan office.

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.
