Ask Tim: Taxes Get Weird With Startup Equity

For a long time, equity compensation sounded like something reserved for Silicon Valley founders, early employees, and the occasional person who somehow knew what a cap table was before the rest of us. Now, stock-based compensation shows up in more offer letters, bonus plans, 401(k)s, and executive benefit packages, which means more people are being asked to make tax decisions before they fully understand what they own.

That can get strange fast. A grant that feels like “future money” may trigger choices today. A benefit meant to build wealth can quietly concentrate risk in the same company that signs your paycheck. And one missed deadline, especially around an 83(b) election, can change the tax math in a very real way.

This week, we are looking at two equity compensation questions: one from a new startup employee trying to understand restricted stock and 83(b) elections, and another from a public-company executive weighing RSUs, stock options, deferred compensation, and company stock inside a 401(k). Let’s dive in.

Why does startup equity come with tax choices before any cash ever hits my pocket?

Dear Tim,

I just accepted an offer with an AI startup, and while the salary feels solid, a big piece of the package comes in equity that currently carries a stated value of $0. Everyone around me talks like those shares could become very valuable once the next funding round lands and, down the road, an IPO enters the picture. That all sounds exciting, though it also feels like I am being handed a puzzle with half the pieces still in the box.

What really threw me was hearing from HR that I may want to look at an 83(b) election right as I begin. I always assumed taxes showed up when shares get sold, so the idea of making a tax decision at grant feels strange. Equity compensation seems to come with its own language, its own calendar, and its own set of traps, and I am trying to figure out why something that sounds like a benefit feels so complicated.

This is my first experience with equity benefits and I am hoping for a plain-English explanation of what an 83(b) election actually does, why timing matters so much, and what risks come with making the wrong move early. More than anything, I want to understand how to think about startup stock in a way that fits the bigger picture of my finances instead of just trusting the buzz around future value.

- Caught in Cap Tables

Dear Caught in Cap Tables,

Equity compensation and benefits come with a myriad of nuances, considerations, tax decisions, and long-term impacts to your financial picture. It’s understandable to be confused as you dive head-first into this arena for the first time!

This sounds like a clear example of Restricted Stock Awards (RSAs) – which can turn into a material driver for wealth accumulation if the startup takes off. The decision before you is an important one and hopefully, I can provide some clarity on why this is being thrown at you so quickly.

To start things off, it’s important to understand how equity compensation, specifically RSAs, work and how they’re treated by the IRS.

It sounds like you received a meaningful grant of restricted stock upon joining the company with potential for more to be received over time. This GRANT simply means that you’re entitled to shares if certain conditions are met. Typically, this is tied to a vesting schedule dictating a certain portion of the shares to be released to you periodically as you stay with the firm.

It’s important to note that by default the GRANT of restricted stock is not seen as an income event by the IRS. It may be part of your compensation but they’re not really yours until they vest!

However, as they VEST and become yours — the IRS treats the FMV of the shares at vestiture as income received by you. Since they're taxed at that value, the FMV of the shares at vestiture also becomes your basis — from which the value may increase/decrease to dictate your capital gain/loss at the time of sale.

To summarize, by default restricted stock is typically held to the following:

Now back to your inquiry on the 83(b) Election and why HR is throwing this decision at you so quickly. The IRS requires this election to be filed within 30 days of receiving the GRANT of restricted stock to be effective.

This is truly time-sensitive, and a decision should be made and sent accordingly to ensure it is received by the IRS before this deadline. If elected, the 83(b) Election filing will change the above tax treatment of the restricted shares received.

Instead of dictating the taxable value at vest, the election allows you to treat the FMV at Grant as taxable income in the year received – effectively setting the basis and holding period to the date of Grant as well.

To summarize, by utilizing the 83(b) Election the restricted stock would be held to the following:

Here is the heart of it: with equity compensation, taxes can arrive when value is received or when vesting happens, rather than waiting until a sale. An 83(b) election lets a person choose to include the value of restricted stock in income at transfer rather than later when the stock becomes vested.

That timing choice matters because early-stage stock may carry a very low fair market value, sometimes even no value at all, as you’re experiencing. If a founder-style or early employee stock grant is taxed while the value is tiny, future appreciation may shift into capital gain territory when shares are later sold, rather than ordinary income at each vesting date. On the other hand, if the company struggles, or if shares are forfeited before vesting is satisfied, a person may have paid tax early on value that never turns into usable wealth.

For example, say you do elect the 83(b) Election. You’d have a tax event but on paper, you shouldn’t generate a tax liability since the following would occur: $0 of ordinary income and a basis set at $0 per share. At Vest, it may be worth $10 per share but you wouldn’t have a tax event until you sold it at the capital gains rate.

If you choose not to file the 83(b) Election, or do so too late, you wouldn’t have a tax event generated during the Grant of the stock. However, you would realize the $10 per share as ordinary income at vest and then you’d have another tax event when the shares are sold at the capital gains rate.

My take: equity feels complicated because it blends compensation law, tax timing, liquidity risk, and startup uncertainty into one package. A good 83(b) decision can be very helpful in the right case, though the right case depends on exactly what landed in your offer letter and what it is worth today.

We see these cases on a regular basis – it’s worth having a qualified wealth manager and tax professional weigh in if you’re still feeling unsure.

How should I weigh company stock in my 401(k) against RSUs, stock options, and deferred compensation?

Dear Tim,

I work for a public company that offers more equity-related benefits as you move higher in the organization, and I have reached the point where several choices are sitting in front of me at once. Inside my 401(k), I’ve been allocating to the Company Stock Fund with a portion of each contribution, and for my newly available bonus I can choose one of Restricted Stock Units, Non-Qualified Stock Options, and Deferred Compensation. I care about the business, I have grown here over the past decade, and I could easily picture finishing my career with this firm rather than bouncing around every few years.

That loyalty makes these decisions feel more personal, because I am drawn to the idea of building wealth alongside the company. At the same time, I realize that each choice likely carries different tax treatment, different levels of risk, and a different effect on my overall balance sheet. What looks generous on paper can also become concentrated exposure, future tax complexity, or a planning headache if I pick based on instinct instead of strategy.

I am trying to get a cleaner handle on what each of these benefits actually does, what tradeoffs matter most, and how each one fits into my broader financial life. I want to think through compensation, retirement savings, taxes, liquidity, and long-term wealth planning as one connected picture rather than treating each election like a separate form to fill out during benefits season.

- Loyal but Learning

Dear Loyal but Learning,

When several equity choices show up at once, the key driver is usually concentration risk versus tax timing. Loving your company and loving your personal balance sheet are two separate jobs. Incorporating these into your broader financial picture and finding the right investment mix to fund your future goals can get tricky fast.

Let us break down the choices and highlight some of the opportunities and considerations within each.

A Company Stock Fund in a 401(k) gives you retirement exposure tied to the same employer already providing your salary and future bonuses. It’s easy to automate the contributions and can even be assigned as Tax-Deferred or Roth.

The opportunities make up a double edged sword. Both of the following can be true, and yet provide you pause to consider where to invest/divest in company equity:

1. The 401(k) will be the easiest place to divest from the company stock to make room for future shares received through bonuses depending on which method you elect to take. This is purely due to the fact that re-allocating your 401k account doesn’t generate taxable activity.
2. Company stock in the 401k can open the door to a clever strategy called Net-Unrealized Appreciation (NUA) Distributions. These allow 401(k) participants to pay ordinary income taxes on the BASIS of their company stock investment and transfer the shares out in-kind to a taxable brokerage account when they retire. Future liquidations are treated as capital gains. This differs as the FMV would otherwise end up in a Rollover IRA with distributions treated as ordinary income and subject to future RMD requirements.

We commonly see clients shed their Roth shares of the company stock in the 401k while retaining the tax-deferred shares to maintain the option of an NUA-styled distribution when they retire. Especially when they need to trim exposure to their employer over time.

Restricted Stock Units (RSUs) generally create ordinary income and set their basis when they vest, and those amounts are usually wages subject to withholding; after vesting, any further gain or loss runs through the capital gain rules when shares are sold.

1. RSUs are not to be confused with RSAs described in the prior response, the 83(b) Election is typically not available for this type of equity compensation.
2. Due to vesting being a taxable event with the basis setting on the same day, clients typically face a decision between 3 options.

Of the three options, clients who pursue an immediate exit strategy typically have the flexibility of liquidating and reinvesting into a diversified portfolio, distributing proceeds for personal needs, or retaining some or all of the company shares at each vest. All determined by their circumstances and what reasonably complements their growing portfolio in that moment.

Non-Qualified Stock Options (NQSOs) usually create taxable compensation when exercised if the option lacks a readily determinable value at grant, and the spread can appear on Form W-2 and is also typically subject to withholding.

1. You don’t own the shares until the option is executed. Options expire if not executed.
2. Can be exercised with external cash, by cash-less exercise, or a combination of the two depending on the custodian facilitating the NQSO compensation plan.
3. Ordinary income tax event, basis setting, and holding periods all begin at time of execution.
4. Once shares are acquired through exercise, selling them is treated as capital gains.

NQSOs are a flexible tool but require you to go in and complete the transaction to acquire them.

Deferred compensation generally means choosing to push income into a future year, usually under a plan governed by Section 409A, which comes with strict timing and payout rules.

1. Can typically elect a set payout schedule (i.e. 5 years after contributed vs. at retirement)
2. Oftentimes operates as a retirement savings bucket beyond the 401(k).
3. Common miss? NQDC plans carry company credit risk. Those amounts are usually an unfunded promise to pay later, which means the account may look tidy on a statement while still depending on the employer’s ability to pay in the future.

So what changes the answer? Your current tax bracket matters. Your expected future bracket matters. Your confidence in the company matters. Your existing exposure matters a lot. If your paycheck, bonus, unvested equity, vested shares, and 401(k) all lean toward the same company, then your household may be far more tied to one corporate story than it first appears. That is usually where a smart compensation plan starts to look lopsided.

Here is a simple example.

Say your annual bonus opportunity is $100,000.

Choice A: take RSUs, vest next year, and assume the share value at vest still equals $100,000. That generally creates $100,000 of wage income then, and future movement after vesting becomes capital gain or loss after sale.

Choice B: take NQSOs with an exercise price equal to current fair market value. If the stock later rises and you exercise when the value reaches $160,000, the $60,000 spread is generally ordinary income at exercise to be withheld in addition to the funds spent (or shares liquidated) to cover the cost of the option. Future movement of shares held after exercise is then treated as capital gain or loss when sold.

Choice C: defer the $100,000 under a deferred comp plan into retirement, which may help if you expect a lower tax rate later, though you are also taking company credit risk and living inside a rigid payout framework.

Match any of the above with the fact that you could have, for example, $1M in Company stock in your tax-deferred 401(k) account with a decades-long basis of $200k. Which presents an enticing opportunity to transition those funds out of future ordinary income treatment and into capital gains treatment when eventually needed in retirement. However, systematically creating a concentrated position depending on how the rest of your portfolio shakes out over the course of your working career.

Here is how I would sort it out this week.

Start by building one master sheet that includes salary, bonus, RSUs, options, deferred comp balances, company stock inside the 401(k), and any shares sitting in taxable accounts.

Then estimate what percent of your household net worth is already tied to this employer.

After that, decide what job each benefit would perform if elected. Maybe the 401(k) handles broad diversification, RSUs become near-term wealth that gets sold on a disciplined schedule, options become upside capital with a risk budget, or deferred comp becomes a tax-smoothing tool for peak earning years. Each tool can be useful; each tool gets messy when it tries to do every job at once. Bonus if you can run a cost/reward estimate on each election option to help you determine the best choice for your unique circumstances.

My take: You’re absolutely right to be thinking about long-term overexposure and the weight that these decisions carry. If you’re looking for a more in-depth analysis, engaging a wealth manager to build out a comprehensive analysis for each option against your overall financial picture will cut down the confusion and provide the clarity you seek. No one option provides a clean “best solution” on face value. It’s most important to find the “best solution for you” during this exercise.
