Google RSUs (GSUs): What to Do When They Vest
Google's GSUs vest front-loaded and often monthly, which creates its own tax and timing traps most guides skip. Here's what to do when they vest.

Google calls its equity grants GSUs instead of RSUs, but the mechanics work the same way. A GSU, or Google Stock Unit, is a promise from Google to give you a share of Alphabet stock on a future date, as long as you're still employed there when that date arrives. Once a GSU vests, it converts into an actual share, and that share is yours to sell, hold, or fold into a broader financial plan.
The vesting itself is the starting line, not the finish line. What happens in the weeks and months after that is where most of the financial upside, and most of the financial risk, lives. This guide walks through the decisions that matter most once your GSUs vest, including one timing trap that catches Google employees more than almost anyone else because of how often their grants pay out.
When a GSU vests, Google often sells a portion of the shares to cover the tax withholding, without any action on your part. This is called sell-to-cover. The shares that are left after that sale land in your brokerage account as Alphabet stock you own outright.
That's the mechanical part. The real question is what to do with the shares you're left holding, and that decision depends on your income, your existing exposure to Alphabet stock, your other financial goals, and how much risk you're comfortable carrying in a single company. There's no universal answer, but there is a clear way to think through it, which is the next question.
A useful way to frame this decision is to ask yourself whether you'd use that same amount of cash to buy Alphabet stock today, on purpose, as a new investment. Running the numbers through our RSU calculator can help put a dollar figure behind that question before you decide. If the answer is yes, holding the shares can make sense. If the answer is no, that's often a signal to sell and redirect the proceeds toward goals that are already part of your plan, like retirement contributions, a home down payment, or diversified investments outside of Alphabet.
This framing matters because RSU and GSU shares can feel different from a deliberate stock purchase, even though the financial reality is the same. The shares showed up as compensation, not as an investment decision, so it's easy to hold them by default rather than by choice. Treating vested shares as new money you're choosing to invest, rather than money you already have and don't want to touch, tends to lead to clearer decisions.
Selling doesn't mean giving up on Google or on Alphabet as a company. It means separating your paycheck from your portfolio, so a downturn in one doesn't hit both at once.
Unvested GSUs are forfeited if you leave Google before they vest, whether you resign or are let go. Vesting is tied to continued employment, and Google does not pay out unvested equity when someone departs. This is standard across most RSU and GSU programs, not unique to Google, but it's worth confirming against your specific grant documents before making any career decision that hinges on an upcoming vest date.
If you're weighing a job change and have a meaningful amount of unvested equity on the table, the vest date itself can be worth factoring into your timeline, alongside compensation, role, and everything else that goes into that decision.
Google's standard vesting schedule weights the earlier years of a four-year grant more heavily than the later years. That's the opposite of a back-loaded schedule like Amazon’s, where later years carry more weight.
This distinction matters if you're comparing offers or thinking about how long to stay somewhere. A front-loaded schedule, like Google's, delivers more of the total grant value earlier in the four-year period. A back-loaded schedule delivers more of that value later, which can create a stronger incentive to stay through the full grant period. Neither structure is better in every case, but understanding which one you're working with can change how you think about timing a departure or evaluating a competing offer.
This is the question most guides skip, and it's the one that can cost Google employees real money. Many Google GSU grants vest on a monthly or quarterly cadence rather than once or twice a year, and vesting cadence has historically scaled with the size of the grant, with larger grants tending to vest more often, according to Levels.fyi. That frequency creates a specific tax problem.
The common advice for RSUs and GSUs is to sell shares as soon as they vest, since there's often little to gain by holding stock you already own for compensation reasons alone. That advice holds up in most cases, but it comes with a caveat that matters when vesting happens monthly. A wash sale occurs when you sell a security at a loss and buy a substantially identical security within 30 days before or after that sale. The IRS then disallows the loss for tax purposes.
Here's where the overlap happens. If your Alphabet stock dips in value between one vest date and your sale of shares from an earlier vest, selling at that lower price can trigger a wash sale, because the new vest is in effect a purchase of the same stock within that 30-day window. The loss gets disallowed, and it gets added to the cost basis of the new shares instead of disappearing, which can create confusion later when it's time to file. This is easy to miss because most people don't think of a scheduled vest as a "purchase," even though the IRS treats it that way for wash sale purposes.
Monthly vesting makes this scenario more likely than annual or semiannual vesting because there are more vest dates in play, and more chances for a sale and a subsequent vest to land inside that 30-day window during a period when the stock is moving. Tracking vest dates alongside sale dates, rather than treating each sale in isolation, is the clearest way to avoid an unexpected wash sale.
There's no fixed percentage that's right for everyone, but as a general rule, our CFP® professionals typically recommend no more than 5% of net worth in any single company's stock or other concentrated position. If Alphabet has a rough year, a portfolio concentrated in one stock can take a hit at the same time your compensation and job security may feel less certain, which compounds the exposure rather than spreading it out.
Diversifying doesn't have to mean an all-at-once sale that creates a large tax bill in a single year. Tax-loss harvesting and direct indexing are two tools that can help spread out the tax impact of diversifying a concentrated position over time, rather than absorbing it all at once. A flat-fee financial plan that looks at your full financial picture, rather than asset management alone, can help you sequence that diversification in a way that fits your income and your other goals, without an assets-under-management fee working against you the whole way.
Vested GSU shares are taxed as ordinary income based on the value of the shares on the vest date, and that income shows up on your W-2. The gap most people miss is the withholding rate. Google, like most employers, withholds federal taxes on supplemental wages like vested equity at a flat 22% rate. GSUs can be taxed at rates up to 44.65% once federal, state, and additional Medicare taxes are factored in for higher earners, according to figures cited by Carta and Empower's The Currency. That gap between the 22% withheld and the rate you may owe is where a lot of people get an unwelcome surprise at tax time.
Setting aside additional funds beyond the automatic withholding, adjusting withholding elsewhere in your finances, or increasing your sell-to-cover percentage at vest can help close that gap before it becomes a bill you weren't expecting. The sell-to-cover adjustment matters most if you're not planning to sell shares right away: if the stock value drops after vest, you can end up holding shares worth less than the tax bill they generated, with little liquidity to cover it. Selling more at vest avoids that mismatch. Our equity comp tax webinar walks through this gap in more detail, along with a few of the other tax traps built into vesting equity.
Once you've decided to sell some or all of a vest, the next question is where that cash goes. For many Google employees, maxing out tax-advantaged retirement accounts is a priority, and a mega backdoor Roth strategy, where available through your 401(k) plan, can allow for more after-tax retirement contributions than a standard 401(k) alone permits. Since 401(k) contributions come out of your paycheck rather than from a separate pool of cash, maxing one out means smaller take-home pay throughout the year. GSU proceeds can help cover that gap, giving you a cushion for regular expenses while more of your paycheck goes toward retirement contributions. For 2026, the total combined limit across employee and employer contributions to a 401(k) is $72,000 for those under 50, per IRS Notice 2025-67, which is the ceiling that mega backdoor Roth contributions work within alongside your regular deferrals and any employer match.
Beyond retirement accounts, proceeds from vested GSUs often go toward a home down payment, paying down high-interest debt, or building out a diversified investment portfolio outside of Alphabet stock. The right mix depends on your full financial picture, which is the kind of thing a comprehensive plan is built to sort out.Google’s standard vesting schedule
