Colorado Supplemental Tax Regulations for Nvidia RSUs

Colorado levies a flat 4.40% individual income tax rate based on federal taxable income, plus a 0.45% Colorado FAMLI (Family and Medical Leave Insurance) payroll premium up to the Social Security wage cap ($184,500). Because employers withhold state tax at the exact 4.40% flat statutory rate, your state-level RSU withholding closely matches your actual Colorado liability.

Colorado Bracket Architecture: 4.40% flat state income tax rate across all income brackets.

Colorado Safe Harbor & Estimated Tax Vouchers (Colorado Form DR 0104EP (Individual Estimated Income Tax))

Colorado requires quarterly estimated payments on Form DR 0104EP if net Colorado tax liability exceeds withholding by $1,000 or more (safe harbor: 70% of current-year or 100% of prior-year Colorado tax; 110% if federal AGI > $150,000).

Multi-State Relocation & Nonresident Sourcing Rules in Colorado

Colorado allocates nonresident and part-year resident equity compensation based on the percentage of business days worked inside Colorado during the vesting period.

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.
