Equity Compensation for Software Engineers: How to Evaluate an Offer
Posted on July 29, 2023 in Guide
Equity can make an offer look dramatically better than it is. A recruiter can put an impressive dollar figure next to salary, while the actual value depends on what you receive, when it vests, whether there is a market for it, and what tax event arrives before you have cash to pay the bill.
That does not make equity a scam. It makes it compensation with a different risk profile from cash. Treat it as a contingent part of the offer until you understand the grant agreement and can explain the terms back to yourself without using the word "upside" as a substitute for arithmetic.
This is a decision framework for U.S.-based software engineers. It is educational material, not tax, legal, or investment advice. A CPA or tax attorney who can read your actual grant documents is worth involving when the numbers are meaningful.
Start With The Instrument, Not The Recruiter's Dollar Figure
"Equity" can mean several very different things.
| Instrument | What you receive | Typical decision point | Main surprise |
|---|---|---|---|
| RSUs | A promise to deliver shares after vesting | Whether to hold or sell after settlement | Taxable wages can arrive before you choose to keep the shares |
| Restricted stock | Actual shares subject to forfeiture or transfer restrictions | Whether an 83(b) election is appropriate | The election deadline is short and the downside is real |
| ISOs or NSOs | A right to buy shares at a strike price | Whether and when to exercise | Exercise, sale, and AMT can create different tax outcomes |
| Phantom stock or SARs | A contractual right tied to company value | Payout timing and plan terms | It may be deferred cash compensation, not ownership |
Do not collapse restricted stock and restricted stock units into one category. Restricted Stock and RSUs for Software Engineers explains the distinction. The short version: restricted stock is property now with restrictions; an RSU is usually a future promise to deliver property. An option gives you a choice to buy; phantom stock gives you a contractual payout, not a shareholder vote.
The Five Questions To Ask Before You Compare Offers
1. What Exactly Is The Grant?
Ask for the plan name, grant type, number of shares or units, strike price if there is one, and a sample grant agreement. If the company is private, ask which share class you would receive and what its rights are relative to preferred stock. An offer that says "$300,000 in equity" is not enough information to evaluate.
For an option grant, calculate the number of shares and strike price. For an RSU grant, confirm whether the value is a fixed share count or a target dollar value that will be converted later. For a private-company grant, understand that a 409A valuation is a tax valuation, not a promise about a future acquisition or IPO price.
2. When Does It Vest, And What Happens If You Leave?
The familiar four-year vesting schedule with a one-year cliff is only the start. Read the agreement for:
- The vesting cadence after the cliff: monthly, quarterly, or annual.
- What happens to unvested awards when you resign, are laid off, or are fired.
- Whether a change in control accelerates vesting, and whether it is single- or double-trigger acceleration.
- The post-termination exercise window for options. It can be much shorter than the original option term.
- Whether a leave of absence or an internal transfer changes the schedule.
An equity grant that requires you to stay four years should not quietly become the reason you remain in a job that stopped being right after eighteen months.
3. What Would It Cost To Get Liquid?
Public-company equity is easier to model because you can sell shares after any company trading windows and policies are satisfied. Private-company equity may have no buyer, company repurchase rights, transfer restrictions, or only an occasional tender offer.
Ask whether employees have had tender offers, whether early exercises are allowed, and who approves a secondary sale. Then model the unattractive case: you leave, need to exercise options, and cannot sell the shares for years. If that scenario would force a loan, a tax surprise, or an uncomfortable concentration in one employer, adjust the value you assign to the grant.
4. When Is The Tax Event?
The tax rules are instrument-specific. The IRS notes that stock-based compensation may create income at grant, exercise, vesting, settlement, or sale, depending on the award. IRS Publication 525 is a useful starting reference, but it cannot interpret your plan for you.
For employees, vested restricted stock and settled RSUs are generally wages reported on Form W-2. The withholding may not cover the final federal and state tax bill, especially after a sharp price increase. Stock options have different rules: ISOs and nonqualified stock options are not interchangeable, and the IRS stock-option overview explains why exercise and sale dates matter.
The practical rule is simple: before an exercise or a large vest, know the estimated tax, your withholding method, and where the cash will come from. Do not assume that selling shares will be possible at the moment the tax is due.
5. How Much Employer Stock Do You Already Own?
Your salary, bonus, health insurance, and career momentum may already depend on the company. Holding a large additional position in the same employer can turn a job problem into a personal-balance-sheet problem.
This does not dictate an automatic sell decision. It does mean you should choose an exposure limit in advance rather than deciding during an earnings blackout, after a price spike, or while reading optimistic Slack messages. A written rule such as "sell enough at each vest to cover taxes, then keep no more than X months of expenses in company stock" is more useful than a vague plan to diversify later.
A Practical Offer-Comparison Worksheet
Compare offers using three columns: certain cash, probable equity value, and speculative upside.
- Put base salary, expected bonus, and benefits in certain cash.
- Put the portion of public-company RSUs you would reasonably expect to vest in the next two years in probable equity value; discount private-company equity for liquidity and execution risk.
- Put IPO or acquisition outcomes in speculative upside, not in the number you use to decide whether you can pay rent or fund retirement accounts.
For a private-company option offer, write down the number of options, strike price, current 409A value, vesting schedule, and estimated exercise cost. That does not tell you the eventual value, but it reveals whether you are being asked to take a financial risk that is wildly out of proportion to the salary.
Documents Worth Reading Before You Sign
The offer letter is a summary. Request and save:
- The equity incentive plan and your grant agreement.
- The stock-option exercise agreement, if applicable.
- The current capitalization or share-class explanation the company is willing to provide.
- The company policy on trading windows, blackout periods, and 10b5-1 plans for public-company employees.
- The change-in-control and post-termination provisions.
If a company cannot answer basic questions about the instrument, vesting, and liquidity, do not fill in the gaps with the rosiest possible interpretation.

The Bottom Line
Equity is valuable when it improves an already sound cash offer and you understand the instrument, liquidity constraints, tax timing, and concentration risk. It is a poor substitute for cash when the company is asking you to accept an opaque valuation and assume costs you cannot comfortably carry.
Ask specific questions, save the documents, and model the boring outcome before you spend time imagining the extraordinary one.
