How an Employee Stock Purchase Plan (ESPP) Is Taxed

One common question from employees with employee stock purchase plans is if there’s an employee stock purchase plan tax. While you’ll typically owe taxes based on the profits when you sell those shares later on, when and how much you’ll owe will be based on the specific nature of your plan. Under a qualified employee stock purchase plan (ESPP), you typically don’t owe any taxes when you purchase shares. However, under a non-qualified ESPP, you’ll owe taxes on any discount you get when you purchase shares. Those are just the basics; let’s take a deeper look at how the employee stock purchase plan tax works.

Want to know how an employee stock purchase plan fits into your financial or retirement planning? Consider reaching out to a financial advisor.

What Is an Employee Stock Purchase Plan (ESPP)?

An employee stock purchase plan is a form of stock option offered by employers as a benefit to their employees. Under this benefit, an employee can purchase shares of company stock through their employer. 

An ESPP works through direct withholding. When you enroll in a plan, you select the percentage of your paycheck you want to contribute to your stock purchase. Your employer directly withholds that amount, and uses the money to purchase company stock on your behalf. Those shares are then placed in a portfolio that you own and control. So if you contribute 3% of your paycheck to your ESPP, your employer would withhold 3% from each of your paychecks and put it toward the purchase of stock on your behalf.

In an employee stock purchase plan, you directly own the shares of stock. They are yours to hold, sell, or otherwise control as you see fit. However, it’s important to note that some companies may require a holding period, which is a minimum amount of time that you must hold the stock before you can sell it.

While employers are free to structure their plan schedule as they see fit, most ESPPs follow three stages:

• Enrollment period: The period in which you declare if you’re enrolling in the ESPP and, if so, state the amount you want withheld.
• Withholding period: Your employer withholds money from your paycheck.
• Purchase: At the end of the withholding period, your employer uses the total amount withheld to purchase stock on your behalf.

For example, an employer might run a quarterly ESPP:

• Enrollment period during the month of January: You have from January 1 until January 31 to enroll in the ESPP.  
• Withholding period through February and March: If you enrolled for this quarter, your employer would withhold your contributions from your paycheck through February and March.
• Purchase period of March 31: Your employer purchases stock on your behalf on March 31.

Under a typical employee stock purchase plan, you can choose to enroll in each purchase period regardless of your past or future participation. You can also choose to adjust your contributions, increasing or reducing your participation for any given enrollment period. Again, this is just a typical structure; employers can design their ESPP withholding and purchase schedule as they see fit.

Value of an Employee Stock Purchase Plan

Under an ESPP, it’s common for companies to offer stock at a discount. This is usually one of the most valuable aspects of an employee stock purchase plan. You can buy company stock at a premium, allowing you to potentially profit from both the company’s future success and the advantaged price you received.

Typically, this discount comes in one of two ways:

• Flat rate: You receive a simple percentage off the stock’s fair market value. For example, your company might offer an ESPP with shares at 10% off the current market price.
• Lookback rates: You receive a lookback rate based on the stock’s market price on a specific date, typically the start of the withholding period. At the time of the purchase, you receive the lower of either the current market price or the lookback price. 

An employee stock purchase plan also has the value of withholding. By automatically deducting your contributions and making this purchase on your behalf, the company simplifies the process of saving and investing. You don’t need to worry about the mechanics of opening a stock portfolio, or plan your finances around money you never receive. 

Taxes on an Employee Stock Purchase Plan

The tax treatment of your plan depends on whether it’s qualified or non-qualified under IRS Code Section 423. ¹

A qualified plan is one that meets the requirements of Section 423. This requires shareholder approval, the plan generally has to be offered to employees on an equal basis and the purchase price cannot be less than 85% of the stock’s market price, effectively limiting the discount to 15%.

If the plan meets Section 423’s requirements, there is generally no tax event when you purchase the shares. Plan participants do not owe taxes at that point based on the discount or other favorable share price.

A non-qualified plan is one that does not meet the requirements of Section 423. This offers employers more flexibility, including the ability to offer discounts greater than 15%. However, non-qualified plans do not receive Section 423’s special tax treatment, and the timing and amount of taxable compensation can depend on how the plan is structured.

For example, say the company’s stock is selling at $20 per share, but your ESPP offers it for $15. Under some non-qualified arrangements, some or all of the $5-per-share discount may be treated as taxable compensation.

Taxes can also apply when you sell ESPP shares, and the tax treatment is not determined solely by whether you held the stock for more or less than one year. With a qualified Section 423 plan, favorable tax treatment generally requires you to hold the shares until at least two years after the option was granted and one year after the stock was transferred to you. Depending on whether you meet these holding periods, part of the proceeds can be taxed as ordinary income and any remaining gain may be treated as a capital gain.

In all cases, the income you dedicate to an ESPP is after-tax income. You will still include that money in your taxable income, and your company will withhold income taxes accordingly.

Tips for Investing in an ESPP

An employee stock purchase plan (ESPP) can be a powerful way to build wealth, giving you the chance to buy company stock at a discount and potentially profit as the business grows. But like any investment tied to your employer, it’s important to approach it with strategy and awareness of both risks and tax implications. Here are some smart ways to make the most of your ESPP while protecting your financial goals.

• Take full advantage of the discount: The biggest benefit of an ESPP is the opportunity to buy company stock below market value, often at a 10% to 15% discount. That discount alone provides an instant return, even before the stock appreciates. If your budget allows, contributing the maximum permitted by your employer helps you capture as much of that built-in gain as possible.
• Understand the holding period rules: The timing of when you sell your ESPP shares affects how your gains are taxed. Holding the stock for at least one year after purchase and two years after the offering date qualifies for favorable long-term capital gains tax rates. Selling too early could mean higher ordinary income taxes on some or all of your profits, so plan your sales carefully.
• Diversify your portfolio: While owning company stock can be rewarding, putting too much of your portfolio into one company, especially your employer, can be risky. Market downturns, company performance issues or job changes could impact both your income and investment value. Maintain a healthy mix of other assets, such as mutual funds or index ETFs, to balance your risk exposure.
• Plan for taxes and cash flow: Because ESPPs are funded through payroll deductions, it’s important to ensure your monthly budget can accommodate the contribution amount. You’ll also want to set aside funds for any taxes due when you sell your shares, particularly if your gains don’t qualify for long-term treatment. Keeping organized records of purchase and sale dates can make tax time much easier.

An ESPP can be a valuable part of your overall compensation and investment strategy, but only if used wisely. Understanding the tax rules, managing risk and maintaining diversification are key to maximizing your returns. A financial advisor can help you create a plan for how and when to sell your shares, so your ESPP becomes a smart, intentional piece of your long-term wealth-building strategy.

Bottom Line

An employee stock purchase plan (ESPP) is a benefit offered by some companies. If you have a qualified plan, you typically won’t owe taxes when you buy the stock. If you have a non-qualified plan, you typically will owe taxes based on the value of the discount you receive. Whether your plan is qualified or non-qualified, you should be prepared to pay taxes on any gain when you sell your shares.

“ESPPs can be a valuable part of your employment. However, the biggest risk that I see clients take is not wanting to sell their accumulated shares of employer stock. In general, I would advise people to consider selling their shares because you don’t want a large portion of your net worth AND your income tied to the same company,” said Matthew Hofacre, MSPFP, CFP®, EA.
