Introduction
If your company offers you equity, you might have to choose between RSU vs stock options: Which One Is Better for You? Both are ways companies give you a piece of the business. But they work very differently.
RSU stands for Restricted Stock Unit. Stock options give you the right to buy shares at a set price. Which one is better? It depends on your situation.
In this guide, you will learn:
- What RSUs and stock options are
- How each one works
- The pros and cons of both
- How taxes affect each one
- Which one might be right for you
Let’s break it down in simple terms.

What Are RSUs?
An RSU (Restricted Stock Unit) is a promise from your company to give you shares of stock. But you don’t get them right away. You have to wait until they vest.
Vesting means you earn the shares over time. Most companies use a vesting schedule. For example, you might get 25% of your RSUs after one year. Then you get the rest slowly over the next three years.
The best part? You don’t pay anything to get RSUs. When they vest, you simply receive the shares. You own them. You can hold them or sell them.
RSUs are very common at public companies and late-stage startups.
How RSUs Work: A Simple Example
Let’s say your company gives you 1,000 RSUs. The stock is worth $10 per share. Your RSUs vest over four years.
- Year 1: You get 250 shares (worth $2,500)
- Year 2: You get another 250 shares
- Year 3: You get another 250 shares
- Year 4: You get the final 250 shares
Each time your RSUs vest, you get actual shares. You can sell them or keep them.
What Are Stock Options?
Stock options are different. They don’t give you shares right away. Instead, they give you the right to buy shares at a fixed price in the future.
This fixed price is called the strike price or exercise price. The company sets this price when they grant you the options.
Here’s the key: You only make money if the stock price goes above the strike price. If the stock price stays flat or goes down, your options could be worth nothing.
Stock options are more common at early-stage startups. They offer more risk but also more potential reward.
How Stock Options Work: A Simple Example
Your company gives you 1,000 stock options. The strike price is $10 per share.
- Scenario 1: The stock price goes up to $50. You can buy shares at $10 and sell them at $50. You make $40 per share. That’s $40,000 profit!
- Scenario 2: The stock price stays at $10. You break even. No profit, no loss.
- Scenario 3: The stock price drops to $5. Your options are “underwater.” They are worthless. You wouldn’t buy shares at $10 when they are only worth $5.
Types of Stock Options
There are two main types:
- Incentive Stock Options (ISOs) – Usually only for employees. They can offer better tax treatment.
- Non-Qualified Stock Options (NSOs) – Can be given to employees, contractors, and advisors.
The main difference is how they are taxed. We’ll cover that later.
RSU vs Stock Options: Key Differences
Here is a simple comparison of RSU vs stock options:
| Feature | RSUs | Stock Options |
|---|---|---|
| What you get | Actual shares when they vest | The right to buy shares at a set price |
| Do you pay to get them? | No | Yes, you pay the strike price |
| When do they have value? | Always have some value (if stock > $0) | Only valuable if stock price > strike price |
| Risk level | Lower risk | Higher risk |
| Common at | Public companies, late-stage startups | Early-stage startups |
| Taxes | Taxed when they vest | Taxed when you exercise or sell |
The biggest difference is simple: RSUs are free shares. Stock options are the right to buy shares.
Pros and Cons of RSUs
Pros of RSUs
✅ No upfront cost – You don’t pay anything to get your shares.
✅ Always have value – As long as the stock is worth more than $0, your RSUs have value.
✅ Simple to understand – You get shares. That’s it.
✅ Predictable – You know exactly how many shares you will get.
Cons of RSUs
❌ Less upside – You don’t get as many shares as you might with options.
❌ Taxes at vesting – You owe taxes when you get the shares, even if you don’t sell them.
❌ No control over tax timing – You can’t choose when to pay taxes. It happens when your RSUs vest.
Pros and Cons of Stock Options
Pros of Stock Options
✅ More upside – If the company grows a lot, you can make much more money than with RSUs.
✅ More control over taxes – You can choose when to exercise your options.
✅ Potential tax benefits – ISOs can offer lower tax rates if you hold them long enough.
Cons of Stock Options
❌ You have to pay to exercise – You need money to buy the shares.
❌ Can become worthless – If the stock price drops below the strike price, your options are worth nothing.
❌ More complex – There are more rules to understand.
❌ Expiration – Options expire after a certain date, usually 10 years.
How Taxes Work for RSUs and Stock Options
Taxes are a big part of the RSU vs stock options decision. Here’s how each one is taxed.
RSU Taxes
When your RSUs vest, the value of the shares is treated as ordinary income. Your company reports this on your W-2.
Example: Your 250 RSUs vest when the stock is $10 per share. That’s $2,500 of income. You pay taxes on that $2,500, just like your salary.
If you sell the shares later:
- If you sell within one year, you pay short-term capital gains (same as your income tax rate).
- If you hold for more than one year, you pay long-term capital gains (usually a lower rate).
Stock Option Taxes
Taxes depend on the type of option:
Non-Qualified Stock Options (NSOs):
- You pay ordinary income tax on the difference between the strike price and the current stock price when you exercise.
- Then you pay capital gains tax when you sell.
Incentive Stock Options (ISOs):
- No ordinary income tax when you exercise (but you might owe Alternative Minimum Tax).
- If you hold the shares long enough, you pay lower long-term capital gains tax when you sell.
Which One Is Better: RSU or Stock Options?
There is no single right answer. It depends on your situation.
RSUs are usually better if:
- The company is public or stable.
- You want lower risk.
- You prefer simplicity.
- You don’t have extra cash to buy shares.
Stock options are usually better if:
- The company is early-stage with high growth potential.
- You can handle more risk.
- You have cash to exercise the options.
- You understand the tax rules.
Important: Most of the time, you won’t get a choice. Your company will offer either RSUs or stock options. But it’s still good to understand what you’re getting.
Common Mistakes to Avoid
1. Not understanding the tax bill
With RSUs, you owe taxes when they vest—even if you don’t sell the shares. Make sure you have cash to pay the tax bill.
2. Holding too much company stock
It’s risky to have all your money in one company. Consider selling some shares and diversifying.
3. Letting options expire
Stock options have an expiration date. If you don’t exercise them in time, you lose them.
4. Forgetting about the 90-day rule
If you leave the company, you usually have about 90 days to exercise your vested options. After that, you lose them.
5. Not knowing your option type
ISOs and NSOs are taxed very differently. Know which one you have.
Frequently Asked Questions (FAQ)
What is the main difference between RSU and stock options?
The main difference is ownership. RSUs give you actual shares when they vest. Stock options give you the right to buy shares at a set price.
Which is better: RSU or stock options?
It depends. RSUs are safer and simpler. Stock options have more risk but also more potential reward.
Are RSUs better than stock options for taxes?
Not necessarily. RSUs are taxed as ordinary income when they vest. Stock options may offer better tax treatment if you have ISOs and hold them long enough.
Do I have to pay for RSUs?
No. RSUs are free. You don’t pay anything to receive them.
Do I have to pay for stock options?
Yes. You pay the strike price to exercise your options and buy the shares.
What happens to my RSUs if I leave the company?
You usually keep any RSUs that have already vested. You lose any that haven’t vested yet.
What happens to my stock options if I leave the company?
You usually have about 90 days to exercise your vested options. After that, you lose them. Unvested options are lost immediately.
Can stock options become worthless?
Yes. If the stock price drops below the strike price, your options are “underwater” and worth nothing.
Can RSUs become worthless?
RSUs always have value as long as the company’s stock is worth more than $0.
Why do startups offer stock options instead of RSUs?
Startups offer options because they expect high growth. Options give employees more upside if the company succeeds. They also cost the company less upfront.
Conclusion
Choosing between RSU vs stock options comes down to your personal situation and the company you work for.
RSUs are simple and safe. You get free shares. You don’t pay anything. But you have less upside potential.
Stock options are riskier. You have to pay to buy shares. They can become worthless. But if the company grows a lot, you can make much more money.
Both can be great ways to build wealth. The key is to understand what you’re getting and plan for the taxes.
Talk to a financial advisor if you’re not sure which is better for you. And always read the fine print on your equity grant.
