Employee value proposition (EVP): A full guide

Employee value proposition (EVP)

When it comes to attracting and retaining top talent, competitive compensation is just the start. Today’s employees want to feel invested in their company’s growth—literally.

An employee stock purchase plan (ESPP) offers just that. ESPPs allow employees to buy company stock at a discount, giving them a direct investment in the business. For employers, stock purchase plans are a simple way to offer staff a meaningful stake in the company. For employees, they're an opportunity to build wealth while supporting the business they help shape.

In this guide, we’ll explain what ESPPs are, how they work, the benefits for employees and employers, and how they affect tax reporting.

What is an ESPP?

An ESPP allows employees to buy company stock at a discounted price—up to 15% off the market price, the maximum allowed under IRS Code Section 423. It’s one of several tools in the equity compensation playbook, alongside virtual stock options, restricted stock units (RSUs), and stock grants—all designed to align company success with employees’ long-term financial goals.

When employees enroll in the program, they select a contribution amount through payroll deductions from each paycheck. Payroll sets aside payments over a defined offering period—typically three to six months—and uses the accumulated funds to periodically purchase company stock on the employee’s behalf at the eligible discounted stock price. Once employees receive their ESPP shares, they can hold, sell, or manage them as they see fit.

Benefits of employee stock purchase plans

An ESPP strengthens the connection between compensation and company performance. When thoughtfully designed, ESPPs benefit both sides of the paycheck: Employees work toward long-term financial goals, and employers build a more invested, loyal team.

Here’s a closer look at how ESPPs support both employees and employers:

For employees

ESPPs are more than an attractive job perk. They create a structured path for employees to save, invest, and participate in the company’s success.

Built-in savings habit: Because contributions come directly from payroll deductions, employees steadily invest in their personal financial goals without extra effort. It’s an easy way to grow passive income while building financial discipline.
A stake in success: ESPPs give employees skin in the game. With each share, they’re not just earning a salary — they’re contributing to something they partially own. That alignment can bring greater meaning to daily work.
Discounted stock purchase: Buying shares at a discounted purchase price offers an instant financial win. It’s a rare opportunity to build long-term equity at below-market rates, adding value from the first payroll deduction.
Flexibility and control: Once employees receive ESPP stock, they can decide how to exercise stock options—hold, sell, or integrate them into a broader investment strategy. Many companies pair ESPPs with financial wellness benefits, like access to a financial advisor, to help employees make informed choices that align with long-term financial goals.

For employers

A well-structured ESPP is a big boost to a company’s compensation strategy, helping attract competitive global talent and retain them through long-term, equity-based incentives.

Retention with real value: When employees hold a tangible stake in the business, they’re more likely to take a future-focused view, both of their careers and their investments. ESPPs help foster that kind of commitment.
Increased engagement: Ownership can drive motivation. Employees who participate in ESPPs often view their performance, the company’s success, and their personal financial growth as closely connected.
Potential tax advantages: Depending on the ESPP’s structure and local tax regulations, companies may qualify for corporate tax deductions. For global organizations, Oyster helps companies design ESPP programs that deliver lasting value for both employees and employers.

How do employee stock purchase plans work?

Before jumping into the mechanics, let’s define the two ESPP types employers can offer under IRS Section 423: qualified and nonqualified plans.

Qualified ESPPs: These stock purchase plans meet specific IRS requirements under Section 423 of the tax code. Employees can purchase company stock at a discount—up to 15%—without owing taxes at the time of purchase. Many programs include a minimum holding period to help purchasers qualify for favorable capital gains tax treatment when they sell the stock.
Nonqualified ESPPs: These plans are more flexible and allow employers to design stock purchase programs without the same IRS restrictions, but they typically don’t offer the same tax advantages.

Whether the ESPP is qualified or nonqualified, the structure and purchasing process generally follow the same steps:

Enroll in the plan: Employees opt in during a designated enrollment period and select a contribution rate between 1% and 15% of their paycheck. For qualified ESPPs, the IRS limits purchases to $25,000 worth of stock per calendar year (based on the stock’s value when the company grants the option). IRS rules also prohibit participation by employees who own 5% or more of the company’s stock.
Make payroll deductions: Payroll withholds the selected amount from each paycheck during a set offering period. These payroll deductions accumulate over time and go toward periodic or one-time stock purchases.
Buy company stock: At the end of the offering period, the company uses the employee’s total contributions to purchase shares. Employers may offer a lookback provision, which applies the discount to the stock’s price at the beginning or end of the offering period, whichever is lower. This gives employees the advantage of both a discount and the lowest stock price available during that window.
Manage ESPP shares: Once the company purchases the stock, employees can choose to hold or sell it. Qualified plans may require a minimum holding period—typically one year after purchase and two years after the grant date—to preserve favorable tax treatment.

How does the IRS tax ESPPs?

The tax implications of an ESPP depend on whether the company plan is qualified under Section 423 of the IRS tax code or nonqualified. This classification determines when employees pay taxes, how much they pay, and whether those taxes fall under ordinary income or capital gains.

Here’s how the two types of ESPPs compare:

Qualified ESPPs

Qualified plans offer the most favorable tax treatment but only if employees meet certain IRS conditions, including the required holding period. If employees meet those conditions, here’s how the IRS treats the purchase and sale of ESPP shares:

No taxes at purchase: Employees don’t owe taxes on ESPP shares until they sell them.
Taxes owed at sale: If employees meet the holding period requirement, the IRS taxes the discount as ordinary income, and any additional gain qualifies for capital gains treatment, which is usually at a lower income tax rate.
Disqualifying disposition: If employees sell before meeting the holding period requirement, the IRS taxes the entire gain as ordinary income.

Nonqualified ESPPs

Nonqualified plans don’t meet Section 423 requirements, so they don’t receive the same tax advantages. The IRS treats them more like a bonus or regular income. As a result, the tax treatment works differently at each stage:

Taxable at purchase: The IRS taxes the difference between the purchase price and the stock’s fair market value as ordinary income.
Taxes owed at sale: Employees pay capital gains tax on any change in value after purchase, since the IRS already taxed the discount portion as ordinary income.

FAQ’s

Is an employee stock purchase plan worth it, or is the discount a trap?

It can be worth it, but only if you treat an employee stock purchase plan like an investment decision—not “free money.” The discount and any lookback feature can create an attractive edge, but you’re still concentrating more of your financial life in one company: your paycheck, your benefits, and now your portfolio. Before you enroll, pressure-test your cash flow (can you handle the payroll deductions without carrying high-interest debt), your risk tolerance (how much of your net worth will end up in one stock), and your exit plan (whether you’ll sell quickly to reduce concentration or hold for longer-term goals). If you’re already overexposed to company equity through options or RSUs, an ESPP can be a great benefit, but it shouldn’t push you into a single-stock situation you’ll regret.

Should you sell ESPP shares immediately, or wait?

“Sell immediately” is a common strategy because it converts a concentrated position into cash and helps you avoid riding your employer’s stock up and down. Waiting can make sense if you’re intentionally investing in the company and you can afford the risk, but you’re taking on price volatility and potentially a meaningful tax trade-off depending on your plan type, your holding period, and your country’s rules. Here’s the thing: the “right” answer is often less about maximizing upside and more about avoiding a painful downside—especially if a stock drop lines up with layoffs or a hiring freeze. Many People teams also forget to warn employees about trading windows, blackout periods, and insider-trading policies, which can limit when you’re even allowed to sell.

What does an employee stock purchase plan example look like in real life?

A practical example: an employee elects a small percentage of each paycheck to be set aside during an offering period, then the plan purchases shares at the end of that period using a discounted price that may be based on a lookback. The employee ends up with shares in a brokerage account (or similar custody setup), and then has a decision to make—hold, sell some to cover taxes, or sell all to reduce single-stock exposure. What’s often missing from “textbook” examples is the operational reality: payroll needs to withhold correctly, the plan administrator needs clean employee data, and employees need clear communications about timelines, enrollment windows, and what happens if they go on leave or change countries mid-offering.

How do ESPPs work for global employees, including Canada?

This is where ESPPs get complicated fast. A plan designed around US rules and US tax timing doesn’t automatically “translate” to other countries, including Canada. You can run into country-specific securities requirements, payroll-withholding expectations, and different tax treatment of discounts and gains. You also have practical issues like funding purchases from local payroll in the right currency and ensuring employees receive the right documents for local tax filing. If you’re employing globally (through entities or an Employer of Record), don’t assume your equity administrator has solved the local compliance work—make it a deliberate part of your rollout plan and communications.

What should HR and Finance track to avoid payroll and reporting mistakes with an ESPP?

The biggest ESPP failures aren’t philosophical—they’re operational. You need clean enrollment data, correct contribution limits in payroll, a reliable feed between HRIS, payroll, and your plan administrator, and a clear owner for exception handling when an employee changes compensation, takes leave, terminates, or moves countries mid-cycle. Finance will also care about predictable expense recognition and reconciliations, and employees will care that payslips and end-of-year documents align with what actually happened. If you’ve ever had to unwind a benefit deduction error retroactively, you already know why this matters.
