Massachusetts Supplemental Tax Regulations for Nvidia 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: 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.
