Estimates only. Not financial advice.
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 BLK today.
Most diversification frameworks would advise against a purchase that size in a single name; the right answer depends on your conviction in BLK. Holding past one year converts the gain to LTCG.

Sell every share at vest; invest the after-tax cash at the market return for 1 yr, then liquidate. Diversified — no single-stock concentration risk.
Hold 1 yr
| Vest value (shares × price) | $80,000 |
| Vest tax (federal + state + FICA) | |
| 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.
