ESPP Tax Treatment for Medtech Executives: What Is Taxed at Purchase and at Sale
By Matt Hightower · October 14, 2026
The mechanics
How Does a Qualified ESPP Work?
A qualified ESPP is one that meets Section 423 of the Internal Revenue Code. It lets employees buy employer stock, usually through payroll deductions, at a discount. Contributions build up during an offering period, and on each purchase date the plan uses the accumulated cash to buy shares. Three features drive the tax result, and each is set by your plan document.
Offering period. This is the window in which contributions accumulate. It may include one or more purchase dates. The first day of the offering period is typically treated as the grant date, and the grant date starts one of the two holding-period clocks discussed below.
Purchase discount. Section 423 requires the option price to be no less than the lesser of 85% of the stock’s fair market value at grant or 85% of its fair market value at purchase. That is why qualified plans commonly offer a discount of up to 15%. Your plan may offer less.
Lookback. Many plans, though not all, apply the discount to the lower of the grant-date price and the purchase-date price. If the stock rose during the offering, the discount is effectively measured from the earlier, lower price, which can make the real discount larger than 15% of the price on the day you buy.
Eligibility also depends on the plan. Section 423 allows a plan to exclude certain highly compensated employees, so an executive may find that the plan available to colleagues is not open to them. Check the plan document before building a decision around it. To see how ESPPs sit alongside RSUs and options, including when each grant type is taxed, our equity compensation guide is a useful companion to this article.
At purchase
Is ESPP Tax Due When You Buy the Shares?
Generally, no. As of October 14, 2026, the IRS states that when you receive a grant or exercise your option to buy stock under a Section 423 plan, you do not include any amount in your gross income. When you sell, you may have to report compensation on your Form 1040 and a capital gain or loss on Schedule D and Form 8949 (see the IRS answer on reporting an employee stock purchase plan).
The deductions that fund the purchase are generally taken from after-tax pay, so an ESPP is not pre-tax the way a traditional 401(k) deferral may be. The amount you pay for the shares is generally your starting cost basis, and your holding period for the shares begins the day after you buy them (see IRS Publication 525).
Payroll taxes work differently from income tax. According to IRS Publication 15-B (2026), wages for social security, Medicare, and FUTA purposes do not include remuneration from exercising an ESPP option or from selling the stock, and federal income tax withholding is not required on the income from a disqualifying disposition or on the discount portion of a qualifying one. In practice, that means little or no tax may be withheld when the income is recognized, so the bill may arrive at filing. State treatment varies.
Holding periods
What Is the 2-Year Rule for ESPP Shares?
The rule has two clocks, and both must run out. As of October 14, 2026, IRS Publication 525 says you satisfy the holding period requirement if you do not sell until the end of the later of:
- 1 year after the stock was transferred to you, or
- 2 years after the option was granted.
A sale that meets both tests is a qualifying disposition. A sale before either clock runs out is a disqualifying disposition.
Which clock is later depends on plan design. If shares are bought less than a year after the offering starts, the two-year-from-grant test is generally the later one, so you may need to hold well beyond one year after purchase. If shares are bought more than a year after the offering starts, the one-year-from-purchase test is generally the later one. Your plan document and Form 3922 show the grant and purchase dates that apply to your shares.
The split
How Is the ESPP Discount Split Between Ordinary Income and Capital Gain?
Qualifying disposition. When the option price was less than 100% (but not less than 85%) of fair market value at grant, Publication 525 says the compensation you report is the lesser of two amounts: the excess of the grant-date value over the option price, or the excess of the value at sale over the amount you paid. Any further gain is capital gain. If the sale produces a loss, it is a capital loss and there is no ordinary income. When the option price was not fixed at grant, as in a lookback plan, Publication 525 figures it as if the option had been exercised at grant.
Disqualifying disposition. Your ordinary income is the amount by which the stock’s value on the purchase date exceeded what you paid. Publication 525 notes this ordinary income is not limited to your gain from the sale. You add it to your basis, and the difference between that higher basis and the sale price is capital gain or loss.
A hypothetical medtech director. Consider a director whose plan offers a 15% discount with a lookback. The stock is $100 on the first day of the offering and $120 on the purchase date six months later, so the plan price is 85% of the lower figure, or $85. She buys 100 shares for $8,500, which are worth $12,000 on the purchase date. For the $25,000 limit discussed below, those shares count as $10,000 (100 shares at the $100 grant-date price). To compare outcomes, assume she sells at $130 a share in each case, once 3 months after purchase and once 20 months after purchase. For the later sale, both clocks have run out: 20 months after purchase is more than 26 months after the offering began.
| Hypothetical result | Disqualifying disposition | Qualifying disposition |
|---|---|---|
| Sale proceeds (100 shares at $130) | $13,000 | $13,000 |
| Amount paid (100 shares at $85) | $8,500 | $8,500 |
| Total gain | $4,500 | $4,500 |
| Ordinary income (compensation) | $3,500 ($12,000 value at purchase less $8,500 paid) | $1,500 (the $15 per share discount at grant, times 100) |
| Capital gain | $1,000, short-term (sold 3 months after purchase) | $3,000, long-term (sold 20 months after purchase) |
The total gain is the same in both columns by construction. What changes is its character: in this example, $2,000 more of it could be taxed as ordinary income in the disqualifying case, which may carry a higher federal rate than long-term capital gain. Actual results depend on bracket, state tax, and other income. The prices are assumptions for illustration, not forecasts, and the figures exclude state tax and any other taxes. If the stock had instead fallen after purchase, the disqualifying sale could still carry $3,500 of ordinary income alongside a capital loss. Hypothetical example for illustration only. Results not guaranteed.
The limit
How Is the $25,000 ESPP Purchase Limit Calculated?
The limit comes from the statute. As of October 14, 2026, Section 423(b)(8) of the Internal Revenue Code (see the text of 26 U.S.C. § 423) says a plan cannot let an employee’s rights to buy stock accrue at a rate above $25,000 of fair market value for each calendar year in which the option is outstanding. That value is determined when the option is granted, across all of the employer’s Section 423 plans.
Two points are easy to miss. The limit uses the grant-date stock price, not the discounted price you pay. And it is not a cap on your cash contributions. At a $100 grant-date price, $25,000 equates to 250 shares for a calendar year, and at an $85 plan price those shares would cost about $21,250. Plans may also set lower caps of their own, such as a percentage of pay, and offerings that span more than one calendar year can be counted differently, so your plan administrator can confirm how your limit is applied.
On the return
How Do You Avoid Being Taxed Twice on ESPP Shares?
The common trap is the basis. Your brokerage may report only what you paid as your cost basis, while the discount has already been counted as compensation. If the return uses the broker’s number unchanged, the same dollars can be taxed once as wages and again as capital gain. In the hypothetical above, a broker basis of $8,500 would make the gain look like $4,500 when the correct capital gain in the disqualifying case is $1,000.
A careful sequence generally looks like this:
- Gather the records. Form 3922 reports the grant date (Box 1), purchase date (Box 2), fair market value on each date (Boxes 3 and 4), price paid per share (Box 5), shares transferred (Box 6), and the date legal title transferred (Box 7). Box 8 may show the price as if the option had been exercised at grant, which is the figure that matters for the qualifying-disposition math in a lookback plan (see the Instructions for Forms 3921 and 3922). Pair it with your Form W-2 and Form 1099-B.
- Classify the sale. Use the two holding tests to decide whether it was qualifying or disqualifying, then work out the compensation amount for that case.
- Increase the basis. Publication 525 says to increase your basis by the ordinary income. Capital gain or loss is measured from that adjusted basis.
- Report the adjustment. The Form 8949 instructions say that when the basis was reported to the IRS, you enter the reported basis in column (e) and make any correction in column (g). If the basis was not reported to the IRS, you enter the correct basis in column (e).
- Confirm where the compensation shows up. The IRS says that if your Form W-2 does not include the amount in Box 1, it is reported on Schedule 1 (Form 1040), line 8k.
Return preparation is a tax-professional task, and the right treatment depends on your own records. The point of the sequence is to know what to ask your CPA for before filing.
Planning questions
When Might Selling Right Away or Holding Be Worth Discussing With a CPA?
There is no rule that fits everyone. Selling soon after purchase may convert the discount into ordinary income, but it also limits how long the shares sit in your portfolio. Holding to reach a qualifying disposition may change the tax character of part of the gain, but it keeps you exposed to the employer’s stock for longer. These are the questions that tend to matter in that conversation:
- How much of your net worth already depends on this one employer through salary, bonus, RSUs, and options?
- What is your expected marginal bracket in the year of sale, and how would the ordinary versus capital gain split change the federal and state bill?
- Would a sale in the same year as an RSU vest or an option exercise push more income into a higher bracket?
- Do you have cash set aside for the tax, given that little may be withheld when the income is recognized?
- Could a price drop during the holding period cost more than the tax difference you were trying to reach?
Working through those questions with your CPA, and with an advisor who can see your whole equity picture, helps turn a general rule into a decision that fits your situation.
Straight answers
Questions about ESPP tax treatment
Generally not. Payroll deductions that fund an ESPP purchase are typically taken from after-tax pay, so they may not reduce your taxable wages the way a traditional 401(k) deferral can. The amount you pay for the shares generally becomes your starting cost basis. Plan details vary, so confirm how your deductions are treated with your plan documents and payroll team.
Under a Section 423 plan, the IRS states that you do not include any amount in gross income when the option is granted or when you buy the stock. Tax generally arises when you sell, and the amount of compensation income versus capital gain depends on whether you met the holding period. State tax treatment may differ, so it is worth confirming with a tax professional.
Under IRS Publication 15-B (2026), wages for social security, Medicare, and FUTA purposes generally do not include remuneration from exercising an ESPP option or from a later sale of the stock. Federal income tax withholding also is not required on certain ESPP income. Because less may be withheld at the time, you could owe more at filing than your pay stubs suggested, which may be worth planning for.
An ESPP may add to the share of your net worth tied to your employer, since your pay, your bonus, and any RSUs or options already depend on the same company. Payroll deductions reduce take-home pay and the cash is tied up until the purchase date. The shares can also fall in value between purchase and sale, and selling early may convert more of the gain into ordinary income. Whether participating makes sense depends on your full picture.
Your employer generally sends Form 3922 when shares are transferred to you. It reports the grant date, the purchase date, the fair market value on each date, the price you paid per share, the number of shares, and the date legal title transferred. For plans with a lookback, Box 8 may show the price as if the option had been exercised on the grant date. Keep the form with your brokerage records until you sell.
