This vest pushes your top federal rate from 24% to 35%. Hover the Federal value below for the bracket-by-bracket slicing.

Heads-up: under-withholding. Your employer withholds federal tax at the IRS supplemental rate (22.0% on this vest, ≈ $17,600). Your marginal federal rate on this vest is 32.7%, owing $26,171. Expect to settle the $8,571 gap at tax time.

The hidden purchase

Tax was paid at vest either way. Holding is mathematically equivalent to taking $44,509 in after-tax cash and buying $44,509 of BL today.

Most diversification frameworks would advise against a purchase that size in a single name; the right answer depends on your conviction in BL. Holding past one year converts the gain to LTCG.

Net at year 1 yr$42,728

Sold 444 shares to cover vest tax (net-settled); kept 556 shares 1 yr to qualify for long-term capital gains.

Social Security + Medicare are payroll taxes (collectively called FICA) — they apply because you're still employed at vest.

Both columns are stated in year-1 yr dollars. The sell side compounds at the market return; the hold side compounds at your single-stock expected return after a 20% volatility drag.

Estimates only. Assumes net-settled (sell-to-cover) vesting; double-trigger and pre-IPO RSUs are out of scope. Excludes multi-state moves, AMT interactions on other equity, and 83(b) elections. Not financial advice.

You evaluated one RSU vest. The beta plans every vest of every grant across years, with concentration and AMT in the loop.
