Massachusetts Supplemental Tax Regulations for Google (Alphabet) RSUs

Massachusetts withholds supplemental RSU wages at the standard 5.0% flat income tax rate. However, under the Massachusetts Fair Share Amendment (Article 44), total annual taxable income exceeding the inflation-adjusted ~$1,000,000 threshold is subject to an additional 4.0% surtax (9.0% total marginal rate), creating an automatic 4.0% state withholding deficit on large equity vests.

Massachusetts Bracket Architecture: 5.0% flat rate on earned wages and long-term capital gains; 9.0% total rate on taxable income over ~$1,000,000; 8.5% on short-term capital gains.

Massachusetts Safe Harbor & Estimated Tax Vouchers (Massachusetts Form 1-ES (Estimated Income Tax Voucher))

Massachusetts requires quarterly estimated payments (Form 1-ES / MassTaxConnect) equal to 80% of current-year tax or 100% of prior-year tax if unpaid state tax exceeds $400.

Multi-State Relocation & Nonresident Sourcing Rules in Massachusetts

Under 830 CMR 62.5A.1, Massachusetts sources nonresident RSU income based on the ratio of Massachusetts workdays to total workdays between the grant date and vest date.

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.
