Schedule 15-Min Safe Harbor Review

Colorado Supplemental Tax Regulations for Meta Platforms 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.

Colorado Safe Harbor & Underpayment Penalties

Pay 100% of prior year or 70% of current year Colorado liability.

Employer Stock Plan Specifics: Charles Schwab Stock Plan Services

Meta vests quarterly on the 15th of February, May, August, and November. With META trading at elevated fair market values, single quarterly vests can easily exceed $50,000–$100,000. If you do not proactively adjust your supplemental withholding rate in Schwab to 37%, you will owe thousands in underpayment penalties.

When vesting at Meta Platforms, Charles Schwab Stock Plan Services 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.
