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 OMC today.
Most diversification frameworks would advise against a purchase that size in a single name; the right answer depends on your conviction in OMC. 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% | $4,451 |
| Cap-gain tax on diversified gain — LTCG (federal + state + NIIT) | −$1,251 |
| Net at year 1 yr | $47,709 |
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.

Formed by a three-way agency merger in 1986, the company holds advertising, media-buying, and public-relations agencies that serve large multinational clients under a holding-company structure. Media buying concentrates client spend into negotiating power with the platforms, while creative agencies provide the relationships that make a client hard to dislodge. The industry's pressure comes from clients moving spend to platforms that sell directly and from consultancies entering the same procurement conversations. Agency headcount is the primary cost, so utilization drives margin. Headquarters are in New York.

Omnicom (OMC) RSUs vest as ordinary income at the price on vest day. The decision is whether to sell at vest and reinvest, or hold the shares through the 12-month LTCG cliff. This calculator runs both paths through the same after-tax math so you can compare like-for-like.
Example: 500 Omnicom (OMC) RSUs vesting at $86.31 per share is $43,155 of ordinary income on vest day. After roughly 32% combined federal + state + FICA (~$13,810), the post-tax share value is ~$29,345. Holding 12 months for long-term capital-gains treatment then only matters for the price change between vest and sale; the ordinary income at vest is already locked in. The calculator runs both paths through the same after-tax math.
