Summary: RSU vs Stock Options
Restricted stock units (RSUs) and stock options are very different forms of equity compensation. RSUs are awarded, whereas employees must buy shares if they have stock options. When RSUs meet all vesting requirements, the full value of the shares is taxable ordinary income – automatically. With options, virtually nothing is automated, so employees must take initiative or risk leaving money on the table. Employees have a lot more control over how their stock options are taxed, which can result in a lower tax bill and more upside, but with greater financial risk. Whether RSUs vs stock options are better often comes down to the stage of the company, the employee’s risk appetite, and their desire (sometimes ability) to do any stock option tax and financial planning.
RSU vs Stock Options: Key Differences
See our article on how employee stock options work and what to know about RSUs: vesting and taxes for reference material.
Grant vs Award
Stock options: Companies issue stock options in the form of a grant. A stock option grant gives the employee the right to buy a certain number of shares of company stock at a set price. Unless the employee leaves the company, a grant is usually exercisable for 10 years.
RSUs: Restricted stock units are called full value awards because when they vest, the employee receives the full fair market value of the vesting shares at no cost. Because RSUs have no purchase price, they are granted as a stock award. This is a key difference between RSUs vs options.
Issuance: Public vs Private
Stock options: Options are typically used in startups and private companies. It is common for public companies to transition to RSUs after the IPO.
RSUs: Due to the tax implications (discussed later), RSUs are more common at public companies and late-stage private companies preparing to IPO (like Anthropic). In recent years it has become more common for private companies to use restricted stock units.
Vesting
Stock options: Options are time-vested. Employees with vested options can exercise their right to buy the stock. Stock options can also have early exercise provisions, allowing employees to exercise before vesting for tax planning.
RSUs: At private companies, RSUs typically have double-trigger vesting, which is usually time-based plus a triggering liquidity event. At public companies, vesting is often time-based. Performance units (PSUs) are another flavor of RSU vesting requirements.
Taxes: RSU vs Stock Options
Stock options: Stock options come in two flavors: incentive stock options (ISOs) and non-qualified stock options (NSOs). How stock options are taxed depends on the type of option you have, the spread at exercise relative to the current value, and your ultimate holding period before sale. Unlike RSUs, employees control the timing and amount of stock options exercises. And because the purchase price of the stock equals the value of the shares when they’re granted, if the value of the company hasn’t changed much or the options are exercised shortly after grant, the tax due could be minimal, even zero.
RSUs: The entire value of RSUs is taxable as ordinary income when the shares vest. Regular W-2 income is subject to federal, state, and local taxes in addition to payroll taxes from Medicare and Social Security. Non-qualified stock options are subject to these same taxes, but only on the spread and with much more control. Due to the tax rules with RSUs, tax planning is more challenging. Unlike restricted stock awards, there is no 83(b) tax election for restricted stock units.
Tax Withholding and Net Holdings
Stock options: Non-qualified stock options have required tax withholding at exercise. Employees can pay for the shares and tax with cash or by selling some of their shares to cover it. Employees can elect to receive the net shares left or net cash and no shares.
RSUs: RSUs also have required tax withholding at vesting, which can be paid with cash or by selling shares. Most RSUs will net settle in stock but cash settlement may be a choice too.
If You Quit or Leave
Stock options: With options, employees usually have 90 days (sometimes longer) to exercise their vested options before losing them. The company may have repurchase rights. You stop vesting when you leave.
RSUs: Like options, time-vested RSUs will stop vesting when you quit or leave the company. RSUs that have already vested (single trigger) are already yours (cash or shares). Double-trigger RSUs usually have different rules. You’ll likely be able to keep your time-vested RSUs while you wait for the second trigger, usually up to 7 years from the original grant date.
Risk vs Upside: RSUs vs Stock Options
Risk
Because employees don’t have to pay for shares of RSUs they’ve been granted, there’s much less financial risk compared to stock options. Unless the stock goes to zero, RSUs will always be worth something. With RSUs, the main risk is paying ordinary income tax on a higher value than you ultimately receive when the stock is sold.
This risk is the highest for double-trigger RSUs. For example, imagine an IPO at $30/share and you have 100,000 time-vested RSUs. Liquidity (the IPO) is the second trigger, so you have a significant tax event with $3M in RSU income. The company must sell a portion of your vesting shares for federal, state, and payroll tax withholding. The remaining shares are stuck in a post-IPO lockup. By the time you can sell the stock, the price is down to $18/share.
Stock options carry more financial risk for employees, but more possibilities for upside too. Employees must pay for the stock. Valuations don’t always increase, so if the company’s 409A valuation or stock price dips below the strike price when the option was granted, there are real implications. If unexercised, the grant is underwater and currently has no value. If exercised, the shares may have a capital loss if eventually sold for less than they were purchased for.
Option holders must also deal with the tax ramifications in the form of regular income at exercise for NSOs and the alternative minimum tax (AMT) for ISOs. Tax planning and tax reporting is much more complex with stock options. At private companies, which typically grant options, there may not be a market to sell stock right away…or ever. It’s an investment, subject to risk.
Upside
Stock options have a lot more upside compared to RSUs. Because employees have a lot of flexibility on when and how to exercise stock options, there’s an opportunity for tax planning that just doesn’t exist with RSUs. For example: planning exercises around tax brackets, spreads, the AMT, or exercising unvested shares with an 83(b) election when the taxable spread is low. Having stock options is often key for tax-free sales of qualified small business stock (QSBS).
Which is Better?
Whether RSUs vs stock options are better will depend on a number of factors, including the employee’s capacity and appetite for tax planning, risk tolerance, liquid assets and cash, the company stage/status, equity and vesting terms, strike price, other equity holdings with the company, and current valuation. If you’re able to negotiate your equity package or choose how you want to receive a bonus, consider all your equity/cash choices, not just stock options and RSUs. But if you are between the two, generally, here’s when restricted stock units or stock options have an edge.
Stock options may be better when:
- Startup to mid-stage private company
- Strike price and per share valuation is still low (a few dollars or less)
- If the company meets the QSBS qualification criteria
- Accelerated vesting provisions for change of control
- Employee-specific: desire to take initiative in stock option and pre-liquidity and pre-IPO planning strategies; has sufficient cash/liquidity to buy the stock; comfortable with risk and more complex equity structures
RSUs may be best when:
- Public, late-stage private company, or an early-to-mid-stage private company offering time-based vesting and net-settled RSUs
- Per share valuation is high and would be prohibitive to purchase as an option
- Employee-specific: desire for straightforward equity participation with fewest decision points; not very comfortable with risk; low liquidity from outside sources; already has significant equity from stock options
Conclusion: RSU vs Options
There’s no universal winner between RSUs and stock options. RSUs offer simplicity and less financial risk. Stock options carry more risk but far more upside and tax planning flexibility, especially at early-stage companies where the strike price is low. If you have meaningful equity, the decisions around exercising, holding, and selling in a tender offer or after an IPO matter, so it’s worth getting advice from a financial advisor for stock options and RSUs before a liquidity event, not after.

FAQ: Restricted Stock Units vs Stock Options
RSUs are shares given to you at no cost once they vest, while stock options give you the right to buy shares at a set strike price. RSUs are taxed automatically as ordinary income at vesting. Options let you control the timing of exercises, which directly impacts how much tax you pay.
Stock options tend to be better at startups to mid-stage private companies with a low strike price, especially if you plan exercises early and around QSBS. RSUs tend to be better at late-stage private or public companies where the share price is high and simplicity matters more than upside.
Vesting stops when you leave. Absent another negotiated agreement, vested stock options must usually be exercised within about 90 days or you lose them. The company may have repurchase rights on your held shares. You already own vested single-trigger RSUs in the form of common stock (or cash, if you already sold). Time-vested double-trigger RSUs can typically be held until the liquidity event, though that ability often expires 7 years from the grant date.
No. There is no 83(b) election for restricted stock units. The 83(b) election applies to restricted stock awards, not RSUs.
Stock options have more financial risk because you pay for the shares at exercise and there’s no guarantee they will ever be worth something. RSUs have less risk since grants have value unless the stock goes to zero. In either case, you can still owe tax on a higher value than you eventually receive.
