Schedule 15-Min Safe Harbor Review

Massachusetts Supplemental Tax Regulations for Nvidia RSUs

Massachusetts withholds at the standard 5.0% flat income tax rate. However, under the Massachusetts Fair Share Amendment, taxable income above $1,000,000 is subject to an additional 4% surtax (total 9.0%), creating a 4% withholding shortfall on multi-million dollar vests.

Employer Stock Plan Specifics: E*TRADE by Morgan Stanley

Due to Nvidia's dramatic stock appreciation, refresher and historical grants produce astronomical vest values. Once your cumulative supplemental wages cross $1,000,000 within a calendar year, E*TRADE increases withholding from 22% to 37%, creating an intra-year cash flow whipsaw.

When vesting at Nvidia, E*TRADE by Morgan Stanley calculates automatic sell-to-cover withholding using Massachusetts's statutory supplemental rate of 5.00% combined with the federal supplemental rate (22% on up to $1M). Because top earners in Massachusetts reach marginal brackets exceeding these rates, you will face an incremental shortfall on April 15.
