Schedule 15-Min Safe Harbor Review

Massachusetts Supplemental Tax Regulations for Databricks 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: Carta / Shareworks

Databricks pre-IPO equity compensation involves RSUs that trigger tax upon liquidity events or structured tender offers. Knowing your exact supplemental gap ensures you reserve adequate cash when participating in company-sponsored secondary sales.

When vesting at Databricks, Carta / Shareworks 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.
