Modera Wealth Management on ESPP planning: when each lot sells and where the cash lands

A 15 percent discount buys a 17.6 percent head start

Most ESPP buyers believe the plan is free money, so they max it out and never sell. The rule is narrower. A 15 percent discount is a 17.6 percent gain on the money you put in (1 ÷ 0.85 = 1.176), but only if you sell near the purchase date and the price doesn't fall. Every share you keep is simply more single-stock risk.

For someone 10 to 15 years from retirement, the pile grows fast. Buying the yearly maximum of $25,000 of stock for 15 years adds $375,000 of company stock at purchase value, before any growth, on top of RSUs and options. The usual family we see has ESPP lots stacking up at the plan broker for years, never sold. Meanwhile bond funds and cash sit in the taxable account while the pre-tax accounts hold the stock funds. That placement is backwards for taxes, and Modera Wealth Management looks at it first.

How does Modera Wealth Management run ESPP planning in four steps?

Modera Wealth Management runs ESPP planning in four steps: collect your plan paperwork, tag every lot with its key dates, price each possible sale against your income, then decide where the cash goes. You end up with a written playbook that lists sale dates and your next enrollment choice. Each step is below.

One habit comes from our view that placement matters as much as picking investments. Before we suggest selling a lot, we write down which account the cash will enter and what that account should hold. A sale with no destination is only half a decision.

What you send in step one

Where the cash goes in step four

• Step 1: send plan document, Forms 3922, lot export
• Step 2: tag long-term and qualifying dates
• Step 3: price each sale against this year's and next year's income
• Step 4: pick the account for the cash

Is an ESPP gain long-term once you've held the shares a year?

Not always. A gain is long-term after one year, but the discount you got at purchase is still ordinary income unless the sale is a qualifying one. A sale qualifies only when it's more than two years from the offering date and more than one year from purchase. Many buyers assume a year of holding makes the whole gain long-term; the IRS rules say otherwise.

A plan under Section 423 limits you to $25,000 of stock per calendar year, valued at the offering-date price, and the discount can be up to 15 percent. Your Form 3922 shows the dates and prices, and the sale is reported on IRS Form 8949. The basis on your 1099-B for ESPP shares often leaves out the discount you already paid tax on, so your CPA has to correct it.

For illustration (hypothetical): Shane and Celeste, 29 and 31, are newly married and both work at a pre-IPO startup. They carry student loans and want to give to charity. A $300,000 tender offer on about $650,000 of startup shares lands this year, which lifts their tax rate. Celeste also holds 400 ESPP shares from an earlier public-company job, bought 10 months ago at $85 when the market price was $100. The shares now trade at $125, so the lot is worth $50,000.

Sold today, the whole $16,000 gain is ordinary income: $6,000 of discount plus $10,000 of short-term gain. At an assumed 32 percent, that's $5,120. Two months later the $10,000 turns long-term: $6,000 × 32 percent = $1,920, plus $10,000 × 15 percent = $1,500, for a total of $3,420. Waiting saves $1,700.

But a $2,000 drop (4 percent of $50,000) would cancel that, since the drop costs $2,000 but cuts the tax by only $300. The decision rule: wait for a lot's one-year mark only when the tax you'd save is bigger than the after-tax loss from the price drop you're willing to risk. Here the breakeven is a fall of about 4 percent. A windfall year, like a tender offer, a bonus or an inheritance, is the year to check lot dates before selling.

Two dates decide the label

Does ESPP planning change if you also hold RSUs or ISOs?

Yes, whenever they land in the same tax year. ESPP disqualifying income adds to the same tax return as RSU vest income, which RSU tax planning covers. It can also shrink the AMT headroom used in ISO exercise planning. ESPP shares count toward the single-stock total that concentrated stock diversification works down.

Five people touch one ESPP sale

You enroll, set the contribution and approve each sale. Modera Wealth Management builds the sale schedule and decides which account receives the cash. The CPA confirms the ordinary income figure and the adjusted basis on the return. An attorney is involved only if shares move into a trust or an estate plan. The plan broker, which is the custodian, holds the lots, carries out the sale and issues the 1099-B.

Can you run ESPP planning on your own while you sell at every purchase?

Yes, if you sell each lot right after purchase. Enroll at every window, save each Form 3922 and check that the year's ordinary income shows up on your W-2. That covers most of what a sell-immediately buyer needs, and it costs nothing.

It's worth calling Modera Wealth Management when lots are held across several years, when a windfall year arrives, when you plan to leave within three years, or when ESPP shares, RSUs and options together make up a large share of what you own. The honest limit: ESPP planning can't take away price risk while you hold shares, and the tax saved by timing a sale is often small next to a normal swing in a single stock. It also doesn't value private startup shares or judge a tender-offer price.

The firm doesn't publish a phone number, so the request form is how you reach us. Fees are set out in a written agreement before any lot is reviewed. Modera Wealth Management works with families nationwide by video call or phone, and the firm's minimum is $500K in investable assets.
