What's different here

The planning considerations that actually apply

Compensation in technology and engineering roles is often weighted heavily toward equity—restricted stock units (RSUs), incentive stock options (ISOs), or non-qualified stock options (NSOs)—creating a concentration problem a purely salaried employee does not have: a meaningful share of both a person's income and net worth can be tied to the same single company. RSUs are taxed as ordinary income when they vest, based on the stock's value at that moment, regardless of whether the shares are sold, which means a large vesting event can create a real tax bill even if the stock is later held rather than sold. Stock options add another layer of complexity: ISOs can qualify for more favorable long-term capital gains treatment if specific holding-period rules are met, but exercising them can trigger the alternative minimum tax (AMT) on the spread between the exercise price and fair market value, even without selling any shares, catching some employees off guard with a tax bill on paper gains not yet realized in cash. Early-stage employees granted restricted stock sometimes file an 83(b) election within 30 days of the grant, choosing to be taxed on the typically low value at grant rather than at vesting—a decision with a strict, unforgiving deadline and real tax consequences either way.

In practice

Two angles worth understanding

Concrete considerations specific to this situation, not a generic checklist with the audience name swapped in.

Managing concentration and liquidity timing

Liquidity events in tech careers often arrive in bursts rather than steadily—an IPO with a lockup period before shares can be sold, an acquisition with a vesting acceleration or a new vesting schedule at the acquiring company, or a secondary sale opportunity at a private company before any public listing exists. Company insiders with material nonpublic information are also subject to blackout windows around earnings releases, and many set up 10b5-1 trading plans to pre-schedule sales during allowed windows, providing a systematic way to diversify out of concentrated stock over time rather than trying to time individual sales around news and rumors. The general planning tension is straightforward to describe and hard to execute emotionally: employer stock that has performed well is exactly the position an employee is most reluctant to sell, and exactly the position that, mathematically, represents the most concentration risk relative to a paycheck already tied to the same company's fortunes.

Coordinating pay, portability, and timing

Frequent job changes, common in tech careers, raise practical questions around portable benefits—rolling over a 401(k) rather than leaving it with a former employer, understanding vesting schedules that reset or are forfeited when leaving a role, and evaluating a new offer's equity component using a realistic valuation rather than the headline number a recruiter quotes, since private-company equity is valued through a 409A appraisal that can differ substantially from the price implied by a later funding round. Health savings accounts (HSAs), when paired with a high-deductible health plan, offer a useful savings vehicle across job changes since the account stays with the individual rather than the employer. Income in these roles can also be lumpy—a large bonus or vesting event in one year followed by more modest years—making multi-year tax planning, rather than a single-year snapshot, the more useful frame for decisions like Roth conversions or charitable giving timing.

Not investment advice

Articles and calculators on this site are for learning. They are not a recommendation to buy or sell any security, and they are not tailored to your personal situation.

Education vs personal advice

If you work with an adviser, that relationship has its own agreements and disclosures. Reading here does not replace that.

No outcome guarantees

Markets are uncertain. We write to explain ideas and trade-offs—not to promise returns or timing.
