Paying alternative minimum tax on an incentive stock option exercise is often not a permanent cost. Much of it can come back as a credit, but only slowly and only under the right conditions. An employee who exercises incentive stock options and holds the shares owes no regular income tax that year. The bargain element, meaning the difference between the fair market value at exercise and the strike price, is instead an adjustment for alternative minimum tax purposes, as descri

The NIIT was designed for high earners, but its thresholds have never been adjusted for inflation. For many Bay Area households, it now applies every year. When it took effect in 2013, the net investment income tax was aimed at a narrow slice of taxpayers. More than a decade of wage growth later, a two-income tech household in Santa Clara County can exceed the thresholds on salary alone. The tax is modest in rate but broad in reach, and it interacts with equity compensation,

Moving to a lower-tax state can be a legitimate financial decision, but California does not take a taxpayer's word for it. Here is how residency is determined and what documentation tends to matter. Conversations about leaving California often begin with tax rates. The state's income tax runs through nine brackets from 1% to 12.3%, plus a 1% surcharge on income over $1 million, and it taxes capital gains as ordinary income. For someone anticipating a large stock sale, the dif

RSU vesting, option exercises, and stock sales rarely have enough tax withheld. Understanding the safe harbor rules can turn an April surprise into a manageable plan. Most employees never think about estimated taxes because payroll withholding takes care of the bill. Equity compensation breaks that assumption. A large RSU vest, an ISO exercise, a tender offer, or a diversifying stock sale can generate income that is under-withheld or not withheld at all. In the Bay Area, the

Self-employment income opens the door to retirement contributions far larger than an employee's deferral limit. The two main vehicles differ in mechanics, paperwork, and who they suit. A growing number of Bay Area professionals earn income outside a traditional paycheck: a laid-off engineer consulting between roles, a product manager advising startups on the side. That income carries a tax burden, since the self-employment tax of 15.3% applies on top of income tax up to the S

An IPO, an acquisition, or an inheritance can change a family's finances overnight. The decisions made in the first year tend to matter more than the ones made in the first week. Sudden wealth arrives more often in the Bay Area than almost anywhere else. A lockup expires or a company is acquired, and an engineer who has spent a decade living on salary is suddenly holding a sum larger than everything earned to date. Friends and relatives have opinions, salespeople appear, and

The headline price of an acquisition is rarely the amount that arrives at closing. Understanding how holdbacks, earnouts, and stock consideration are taxed helps sellers plan for cash they cannot yet spend. The press release says the company sold for $200 million. The closing statement shows something smaller, with a portion held in escrow, another portion contingent on hitting targets over the next two years, and perhaps a slice paid in the acquirer's shares. Each piece has

The entity you form on day one shapes how profits are taxed, what investors expect, and whether a future exit can qualify for the qualified small business stock exclusion. Entity choice is one of the first decisions a founder makes and one of the hardest to reverse cheaply. The Silicon Valley default, a Delaware C corporation, fits most venture-backed startups, but a consulting practice or a profitable software tool with no plans to raise capital may be better served by an LL

Writing checks to friends' startups is a Silicon Valley tradition. Doing it without undermining the rest of a financial plan takes discipline about size, expectations, and taxes. At some point in a Bay Area tech career, the invitation arrives: a former colleague is raising a seed round and wonders whether you would like to participate. Angel investing offers a chance to support people you believe in and possibly earn a return that public markets rarely deliver. It also offers

The two most common early-stage instruments look similar on a term sheet but can be treated very differently by the tax code, especially when it comes to qualified small business stock. Most Bay Area angel investments no longer involve buying shares. They involve signing a SAFE, the simple agreement for future equity that Y Combinator introduced in late 2013, or a convertible note, and waiting for a priced round to turn that document into stock. According to Carta, SAFEs acco

Transferring private company stock to a trust while its value is still modest can move future appreciation out of a taxable estate. The technique is powerful, irreversible, and easy to get wrong. Estate planning tends to be an afterthought for founders and early employees until a banker mentions an IPO. Shares valued at a few dollars each under the company's latest appraisal may be worth many multiples of that within a year or two, and a gift made at today's value uses only t

An acquisition, a tender offer, or a personal need for cash can force a sale of qualified small business stock before the holding period is met. Section 1045 offers a way to keep the clock running. The qualified small business stock exclusion is one of the most valuable provisions in the tax code for Bay Area founders and early employees, but it comes with a waiting period. Stock acquired before July 5, 2025 must be held more than five years for any exclusion, and stock acqui

Selling a slice of founder stock before an exit can reduce personal risk, but the mechanics, the taxes, and the optics all require care. A founder who has spent six years building a company may hold tens of millions of dollars of paper wealth and very little cash. Selling a portion of that stock in a secondary transaction, often alongside a financing round, has become a normal part of the private company landscape. In the first half of 2026, Carta counted 71 tender offers on

Founders often underpay themselves for years while carrying Bay Area living costs. Here is how salary, entity type, and payroll taxes interact, and what a sustainable plan may look like. Most founders start a company with equity in mind and salary as an afterthought. Yet a founder who cannot cover rent, childcare, and health insurance is under a kind of pressure that tends to produce poor decisions. In a region where the median single-family home in Santa Clara County was rou

The grant notice is one page. The plan behind it can run fifty. A few of those pages decide what happens to your equity when the company is sold, when you leave, or when something goes wrong. Most employees read the grant notice, check the share count and vesting date, and file the rest away. That is understandable, but the plan document and award agreement contain terms that only matter at moments of high stakes: an acquisition, a departure, or a restatement of the company's

Leaving the state does not leave your California tax history behind. Equity earned while you worked here may remain partly taxable here for years after the move. Remote work and the cost of Bay Area housing have prompted many technology employees to relocate to states with lower or no income tax. A common assumption is that once you move, future RSU vesting and option exercises are taxed only by the new state. California's rules are more complicated than that. The Franchise T

Two offers with the same total grant can deliver very different amounts of stock in year one. The vesting schedule, not the headline number, determines what you actually receive. Equity compensation at Bay Area companies used to follow a nearly universal template: four years of vesting with a one-year cliff, then monthly or quarterly installments. That template still describes most startup grants, but public companies and late-stage private companies have introduced a wide ra

The number that sets your strike price is produced by a process most employees never see. Here is what it is, why it moves, and why it is not the same as what your shares are worth. If you hold options at a private company, your strike price was almost certainly set by a 409A valuation. The term comes from Section 409A of the tax code, which governs deferred compensation and imposes penalties when options are granted with a strike price below the fair market value of the unde

A headline share count tells you very little. The value of an equity offer lives in the details, and most of them are fair game to ask about. Equity is often the largest variable in a Silicon Valley job offer, and also the least understood. An offer of 40,000 options or $400,000 in RSUs sounds concrete, but its real value depends on the company's capital structure, the vesting terms, the tax treatment, and what happens when you leave. Asking good questions before you sign doe

Leaving a startup starts a timer on your vested options. Knowing how long you have, and what the tax code does at three months, can prevent an expensive surprise. When you leave a private company, your unvested options are gone, but your vested options survive for a limited time called the post-termination exercise period, or PTEP. For decades the standard has been 90 days. According to Carta's research on post-termination exercise periods, 82% of companies on its platform ha
