My RSUs Just Vested - Am I Now Locked Out of a Roth?

You checked your paycheck, and the numbers finally look the way you've always wanted them to. Your company just released a massive block of Restricted Stock Units (RSUs), and your compensation hit a completely new tier this year. So, doing the responsible thing, you max out your Roth IRA for the year to lock in some tax-free growth. If you're building a broader Roth conversion tax planning strategy, a direct contribution feels like the natural first step.

But there's a brutal piece of tax math nobody warns you about when you get your first big equity payout. When your RSUs vest, the IRS treats the gross value as ordinary income. That sudden spike in your Modified Adjusted Gross Income (MAGI) can instantly push you over the RSU Roth income limit, turning your perfectly legal Roth contribution into an illegal "excess contribution" overnight. And the penalty clock starts ticking immediately.

I see this trap catch equity-compensated employees every single year. Let's break down exactly how your RSUs poison your Roth eligibility—and how to fix it before you owe the IRS a penalty.

Does RSU vesting increase my MAGI for Roth IRA limits?

Yes. The most dangerous mistake you can make is assuming that because you didn't sell your RSUs, they don't count as income yet.

Under IRC §83(a), the moment your RSUs vest and are no longer subject to a "substantial risk of forfeiture," the entire fair market value of those shares is included in your gross income. It does not matter if you hold the stock for ten years or sell it the same afternoon. The vest itself is the taxable event.

That vested amount flows straight into your W-2 as supplemental wage income, which increases your Adjusted Gross Income (AGI) dollar-for-dollar. For 2026, the ability to contribute directly to a Roth IRA phases out entirely once your MAGI hits $165,000 (if you file Single) or $246,000 (if you're Married Filing Jointly). If your base salary is $130,000, you might feel safe. But if $50,000 worth of RSUs vest in November, your MAGI just spiked to $180,000. You are now officially locked out of the front door to a Roth.

The Supplemental Withholding Blindspot

Here is where the math gets even crueler. When your $200,000 RSU block vests, your employer will automatically withhold a chunk of those shares to cover taxes—usually at the statutory supplemental rate of 22%.

You might look at your brokerage account, see only $156,000 worth of "net" shares deposited, and assume that's the number the IRS cares about.

It isn't. The IRS calculates your MAGI based on the gross value of the shares that vested, before a single dollar was withheld for taxes. The full $200,000 is piled onto your income. The shares withheld to pay taxes were simply the mechanism you used to pay the bill; they don't reduce your gross income. If you are calculating your Roth eligibility using your net share deposit, you are almost certainly underestimating your MAGI.

The "Double Tax" Trap of an Excess Contribution

Let's say you contributed your $7,000 to a Roth IRA in January, completely unaware that a November RSU vest was going to push you over the 2026 income limit. What happens now?

You now have an "excess contribution." The IRS imposes a harsh 6% excise tax (under IRC §4973) on that $7,000 every single year it remains in the account. This isn't a one-time slap on the wrist; it's a compounding penalty that bleeds your account until you fix the error. You contributed after-tax dollars to avoid taxes in retirement, and instead, you bought yourself an immediate penalty.

If you catch the mistake early, the correction mechanism is straightforward: you must "recharacterize" the contribution (along with any earnings it generated) into a Traditional IRA, or withdraw the excess entirely by your tax filing deadline, including extensions. But if you don't realize your RSUs disqualified you until years later, the cleanup is painful and expensive. If you have already crossed this line, step-by-step triage is required to fix the backdoor Roth mistake and stop the bleeding.

I'm Married Filing Separately. Does the RSU limit still apply to me?

It's actually worse. A common edge case I see involves married couples who file separately—often to keep income-driven student loan payments low. One spouse earns $90,000 and has $15,000 in RSUs vest. They think, "I'm well under the $165,000 Single limit, so I'm fine."

They aren't. Under IRC §408A(c)(3)(B), if you are Married Filing Separately and you lived with your spouse at any time during the year, your Roth IRA contribution limit begins phasing out at the very first dollar you earn, and is completely gone at $10,000.

For these couples, the RSU vest is actually irrelevant to their Roth eligibility—they were locked out from day one. The vest just increased the tax liability on their already-disqualified income.

How to navigate the RSU Roth limit safely

For highly compensated employees receiving equity, the safest strategy is patience. Do not contribute to your Roth IRA in January. Wait until year-end, or after your final RSU vest of the year, to calculate your true MAGI. Only then should you make your contribution for that tax year (you have until April 15th of the following year to do so).

If you run the math in December and realize your RSUs have permanently locked you out of direct Roth contributions, you aren't out of options. You can pivot to a Backdoor Roth strategy, which involves making a non-deductible contribution to a Traditional IRA and immediately converting it to a Roth. Because there are currently no income limits on Roth conversions, your massive RSU vest won't stop you.

Just be incredibly careful. If you have any existing pretax money sitting in an old IRA, a Backdoor Roth will trigger the Pro Rata Rule, which taxes your conversion proportionally based on your total IRA balances. It can be just as punishing as an excess contribution penalty.
