Your RSUs Are Not a Bonus: An Equity-Comp Field Guide for Salt Lake Professionals

A growing share of Wasatch Front pay arrives as stock — on a schedule, with a tax bill attached, and with a quiet concentration problem nobody mentions at the offer stage.

By Ryan Hammett · July 2026

The offer letter said "$120,000 in RSUs." What it didn't say: when it becomes taxable, why the default withholding is probably short, what the ESPP fine print is worth, or how five years of vesting quietly turns a diversified saver into a one-stock investor. Here's the field guide — educational, not advice.

I'm Ryan Hammett, an independent fiduciary in Layton who works with tech and professional households across the Salt Lake Valley and the Lehi corridor. Equity compensation is the most common thread in those conversations — and the most commonly misunderstood. Not because people aren't smart; because nobody teaches it, and the defaults are engineered for the company's convenience, not yours.

Vesting Is Income. Holding Is a Decision.

Start with the one sentence that reorganizes everything: when RSUs vest, you've been paid. The market value of the shares that vest is ordinary income on that day — it lands on your W-2 exactly as if it were salary, whether or not you sell a single share. There is no "waiting for long-term gains" on the vest itself; that clock only starts on growth after vesting.

Which exposes the default nobody questions: doing nothing. Keeping vested shares feels prudent — loyal, even. But since the tax is owed either way, holding is exactly equivalent to receiving a cash bonus and spending all of it on your employer's stock. Some people would do that deliberately, with a limit. Almost nobody would do it accidentally, forever — yet that's what "I just never sold" is.

The Withholding Gap: Why April Stings

22%
Standard federal supplemental withholding on RSU income up to $1 million (37% above that)
32–37%
Where many dual-income tech households actually land — the gap between this and 22% becomes an April tax bill
3.8%
Net investment income tax on investment gains above $200k single / $250k joint MAGI — the quiet add-on

Here's the mechanical trap: employers usually withhold RSU income at the IRS flat supplemental rate of 22%. If your household's marginal rate is 32% or higher — common for a dual-income couple with meaningful vests — every vest under-withholds by ten to fifteen points. On $150,000 of vesting income, that's a $15,000–$22,000 surprise, arriving all at once at filing time, sometimes with an underpayment penalty attached.

The discipline that fixes it: treat every vest date as a mini tax event. Know your real marginal rate, set aside or pre-pay the difference, and coordinate quarterly estimates with your CPA. Boring, mechanical — and it converts April from an ambush into a non-event.

The ESPP: Read the Fine Print, It's Usually in Your Favor

Employee stock purchase plans are the most underused benefit I see. A qualified Section 423 plan lets you buy company stock at up to a 15% discount, often with a lookback — the discount applies to the lower of the price at the start or end of the purchase period. In a rising stretch, the effective discount can be far better than 15%. Plans cap purchases (typically at $25,000 of stock value per year), and the tax treatment depends on how long you hold: a qualifying disposition generally requires holding two years from grant and one year from purchase.

The honest framing: the discount is close to the nearest thing compensation offers to free return — if you participate, and if the shares don't just pile up alongside your RSUs, deepening the same concentration. For many households, the pattern that works is participating fully and diversifying on a schedule, with the tax rules — not vibes — deciding the timing. Your CPA should bless the specifics.

Concentration: The Risk That Compounds Quietly

Now zoom out. Salary from the company. Bonus from the company. RSUs vesting quarterly. ESPP purchases twice a year. Maybe options. Five years in, it is completely ordinary for a third to half of a household's net worth to depend on one ticker — the same ticker that signs the paychecks. If the company stumbles, the job and the portfolio stumble together.

It is genuinely thrilling to watch your company's stock climb. Thrilling is not a plan. The professionals who navigate this well almost all converge on the same structure:

A concentration ceiling

A written limit — commonly 10–20% of investable assets in employer stock. Above the line, selling is automatic, not a debate with yourself.

A standing sell schedule

Sell-at-vest (simplest, no new tax beyond the vest itself) or a calendar-based schedule. For insiders, a 10b5-1 plan makes it rule-based and defensible.

A destination for proceeds

Diversified portfolio, mega-backdoor Roth if your plan allows it (the overall 2026 401(k) additions cap is $72,000), 529s, or the house fund — sold shares need somewhere purposeful to go.

A tax calendar

Vest dates, ESPP purchase dates, estimated-payment dates, and year-end on one calendar, shared between you, your advisor, and your CPA.

One thing this article is not: a prediction about any company's stock, including yours. The case for diversification doesn't depend on your company doing badly — it depends on the arithmetic that your salary already bets heavily on it doing well.

Is This the Kind of Help You're Looking For?

We may fit if

  • Equity is a meaningful slice of your pay and nobody has ever mapped the vesting, taxes, and concentration on one page.
  • You want a written sell-schedule and a destination for the proceeds — approved by you, trade by trade.
  • You want your advisor and CPA working the same plan instead of guessing at each other.

We probably don't if

  • You want validation for going all-in on your employer's stock. That's not advice; I won't dress it up as advice.
  • You want stock picks or market timing.
  • Your equity comp is small and sell-at-vest into an index fund honestly covers it — I'll tell you that in one call, free.

Common Questions

Why did I owe money at tax time even though my RSUs were withheld?

Employers typically withhold RSU income at the flat 22% supplemental rate (up to $1 million), while many professional households actually owe 32–37% on that income. The shortfall becomes an April bill. The fix is anticipating it — adjusted withholding, estimated payments, or setting the gap aside at each vest.

Should I hold my RSUs after they vest?

Holding is a choice, not a default. The tax is owed at vest regardless — so ask: if this had arrived as cash, would I buy my company's stock with it? Deliberate holding with a written limit is a strategy. Accidental holding with no limit is just concentration.

Is my ESPP worth participating in?

A qualified plan with a 15% discount — especially with a lookback — is often one of the strongest benefits you have, within the typical $25,000-per-year limit. The discount is real return; the risks are stacking more employer stock and fumbling the qualifying-disposition tax rules. Participate, then diversify on a schedule, with your CPA on the timing.

What is a 10b5-1 plan and do I need one?

A pre-arranged, rule-based schedule for selling company stock, established while you don't hold material non-public information. For insiders it provides an affirmative defense while diversification runs automatically. Whether you need one depends on your role and your company's trading policy — loop in your company's legal team.

Do you coordinate with my CPA?

Yes — this only works when the investment side and tax side agree. I build the vesting map and sell schedule; your CPA and I coordinate the estimates, elections, and year-end moves. No CPA yet? I'll tell you honestly when your situation needs one.
