Your RSUs After a Layoff: Tax Deadlines You Can't Miss

The email comes on a Tuesday. Your role is eliminated. Your mind jumps to severance, health insurance, the next job. But buried in the separation paperwork is a set of deadlines that could cost you hundreds of thousands in unnecessary tax if you miss them. The RSU withholding shortfall that surprised you in April is just the beginning — now the same math applies to severance, unvested shares, and a ticking clock on your stock options.\n\nIf you've been relying on your employer's RSU withholding to cover your tax bill, a layoff changes everything. A severance payment taxed at the supplemental withholding rate, forfeited unvested shares, and a short window to decide what to do with your stock options all hit at once. Here is the order of operations.\n\n## What Happens to Your RSUs When You Are Laid Off\n\nThe answer splits in two: vested and unvested.\n\nVested RSUs are yours. Any restricted stock units that have already settled into shares belong to you. The shares are in your brokerage account. The layoff does not take them back. But there is a catch: if a chunk of RSUs vested right before the layoff as part of a separation agreement, you may have an unexpectedly large tax bill coming from those shares. Your employer withheld at the standard 22% supplemental rate (or 37% above $1 million), but that may not cover your actual marginal rate, the extra 0.9% Medicare tax on high earners, and California's top rate of 12.3%. (The 3.8% net investment income tax doesn't apply when RSUs vest. It only applies later, to any gain when you sell the shares.) This is the same RSU withholding gap that surprises tech employees every April, only now you have no future payroll to adjust against.\n\nUnvested RSUs are almost always forfeited. When you leave, any RSU grant that has not reached its vesting date disappears. There is no tax consequence for losing unvested shares — you never owned them — but the forfeited value is gone. If you were counting on those future vesting events to fund a planned move or a major purchase, that timeline just changed.\n\nOne thing worth checking: your severance agreement may include an acceleration clause that vests a portion of unvested RSUs. Some companies, particularly during broader layoffs, will negotiate this as part of the separation package. It is the single most valuable thing to ask for.\n\n## Stock Options After Termination: The 90-Day Clock\n\nStock options are different from RSUs, and the rules are tighter.\n\nWhen you leave, your incentive stock options (ISOs) and non-qualified stock options (NSOs) enter a post-termination exercise period. The standard window is 90 days, though some companies give 30 days and a few give as long as 12 months. Check your plan document. If you do not exercise within that window, the options expire worthless.\n\nThe exercise window creates a painful choice for ISOs. Exercising ISOs within 90 days of leaving means you keep the shares and a shot at long-term capital gains treatment. But the spread between the grant price and the fair market value at exercise triggers the alternative minimum tax (AMT), and in a layoff year you may not have the cash to pay it. If you cannot exercise, or choose not to, the ISO shares convert to NSO treatment — or vanish if the window closes.\n\nFor NSOs, the calculation is simpler. Exercising within the window creates ordinary income on the spread, taxed at your marginal rate. The withholding at exercise can be significant. If you plan to exercise, make sure you understand the cash needed for the tax.\n\nUnderstanding how RSUs and options reshape your overall tax picture before the layoff hits is the best defense, but even post-layoff the order you handle these decisions matters.\n\n## Severance and RSUs: What to Negotiate\n\nYour severance agreement may reference your equity. Read that section carefully.\n\nSome companies include a provision that accelerates a portion of unvested RSUs or extends the option exercise window beyond 90 days. Neither is standard, but both are negotiable — especially in a reduction in force where the company is trying to make the package acceptable.\n\nOn the tax side: severance pay is treated as supplemental wages. Your employer withholds at the 22% flat rate (or 37% if the severance pushes you over $1 million for the year). That is probably too low for your actual combined federal and state rate if this was a high-income year before the layoff. You may need to make an estimated tax payment to avoid an underpayment penalty.\n\nIf you received a significant severance, consider how it interacts with the income you already earned this year. A large severance on top of several months of salary and a final RSU vest could push you into a bracket where every additional dollar is taxed at more than 50% when you add federal, state, and Medicare taxes together. Diversifying a concentrated stock position without triggering a tax catastrophe becomes even more important when your income is already high for the year.\n\n## The Gap Year: Your Best Tax Window\n\nIf you are laid off early enough in the year and do not land a new job immediately, you may have a low-income window that is the most valuable tax planning opportunity you will see for years.\n\nHere is what to consider doing in a gap year:\n\nRoth conversions. Your marginal rate may drop to 22% or even 12% for the year. Converting a portion of your pre-tax 401(k) to a Roth IRA at that rate instead of your usual 35% saves a significant amount over your retirement. The conversion is taxable as ordinary income, so keep the total within the bracket you are willing to pay.\n\nZero percent long-term capital gains. If your total taxable income for the year falls below $49,450 (single) or $98,900 (married filing jointly) for 2026, you pay 0% federal tax on long-term capital gains. If you've been holding appreciated shares from vested RSUs, this is a rare chance to sell them with no federal tax on the gain. California will still tax the gain, but you avoid the federal layer entirely.\n\nNet unrealized appreciation (NUA). If your 401(k) holds company stock, a lump-sum distribution after separation lets you pay ordinary income tax only on the cost basis. The appreciation stays as a long-term capital gain. In a low-income year, the ordinary income on the basis may be minimal. This strategy requires a full distribution of the 401(k) within one calendar year and is worth running the numbers on.\n\nLearn more about Roth conversions during a lower-income gap year and whether the math works for your situation.\n\n## When to Call a Strategist\n\nA layoff adds complexity to your tax picture at the worst possible time. You are already making decisions about health insurance, job search, relocation, and maybe a move out of California. The equity decisions have deadlines measured in weeks, not months.\n\nIf you hold stock options that require a decision within 90 days, or you are sitting on a large pile of vested RSU shares from years of vesting, talk to a tax strategist before the exercise window closes. We work with tech employees navigating exactly this — working with a tax strategist who understands equity compensation means you get the plan before the deadline, not after.\n\nBook a free 15-minute discovery call at (619) 280-2700 or email info@RoadmapTax.com to walk through your post-layoff equity decisions.\n\n## FAQ\n\n### What happens to unvested RSUs when I am laid off?\n\nThey are almost always forfeited and revert to the company. You do not owe tax on unvested shares you never received, but the value of those future vesting events is lost. Check your severance agreement for a possible acceleration clause.\n\n### How long do I have to exercise my stock options after leaving a job?\n\nThe standard window is 90 days from your termination date, but some companies give only 30 days. Check your stock plan document or grant agreement for the exact period. After it expires, unexercised options are forfeited.\n\n### Do I pay taxes on severance pay differently than regular income?\n\nSeverance is treated as supplemental wages and your employer withholds at 22% (or 37% above $1 million). If your actual marginal rate is higher, you may need to make an estimated tax payment to cover the difference and avoid an underpayment penalty.\n\n### What is the gap year strategy for tax savings?\n\nIf your income drops significantly after a layoff, you may qualify for a lower tax bracket. That creates opportunities to do Roth conversions at a reduced rate, sell appreciated shares in the 0% long-term capital gains bracket, and potentially use net unrealized appreciation on employer stock in your 401(k).\n\n### Should I sell my vested RSU shares after being laid off?\n\nIf you hold a concentrated position in your former employer's stock, a layoff is a natural moment to consider diversification. Selling now may mean a lower capital gains rate depending on your total income for the year. Talk to a tax strategist about the timing.\n\n### Can I negotiate equity terms in my severance agreement?\n\nYes. Severance agreements are negotiable, especially during company-wide layoffs. The most valuable things to ask for are accelerated vesting of some unvested RSUs and an extended option exercise window beyond the standard 90 days.\n\n---\n\nThis article is for educational purposes only and does not constitute tax, legal, or investment advice.
