Colorado Supplemental Tax Regulations for Databricks RSUs
Colorado levies a flat 4.40% income tax rate on all taxable income. Employers withhold at 4.40%, meaning state withholding closely tracks true state liability.

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 Colorado's statutory supplemental rate of 4.40% combined with the federal supplemental rate (22% on up to $1M). Because top earners in Colorado reach marginal brackets exceeding these rates, you will face an incremental shortfall on April 15.
