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 32.6%, owing $26,065. Expect to settle the $8,465 gap at tax time.
The hidden purchase
Tax was paid at vest either way. Holding is mathematically equivalent to taking $44,615 in after-tax cash and buying $44,615 of HAWK today.
Most diversification frameworks would suggest no, but the right answer depends on your conviction in HAWK. Holding past one year converts the gain to LTCG.
Sell + invest
Best payout| Vest value (shares × price) | $80,000 |
| Federal | |
| State | |
| Medicare | −$1,160 |
| Additional Medicare | −$720 |
| Market gain over 1 yr at 10.0% | $4,462 |
| Cap-gain tax on diversified gain — LTCG (federal + state + NIIT) | −$1,254 |
| Net at year 1 yr | $47,823 |
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 | $42,830 |
Sold 442 shares to cover vest tax (net-settled); kept 558 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.
