Navigating Stock Compensation: How Are RSUs Taxed When Sold in 2026?

Roughly 7 to 10 million U.S. employees get equity compensation. That statistic includes far more than just executives. Restricted stock units (or RSUS) have become a standard tool for building wealth.

But here’s the real problem. From our experience, most people hand over extra money to the IRS simply because they miss how the two‑stage tax structure works. 

So, how are RSUs taxed when sold?

This article walks you through the vesting event, the sale itself, and the tax implications that catch so many off guard. You’ll learn exactly what triggers income tax at vesting versus capital gains later so you can lower your total tax liability from stock compensation.

We’ve covered how RSUs are taxed in a previous article. Next up, you’ll see our guide on RSU finance. And for a discussion on a specific industry, check out the main post on restricted stock units tax strategy for oil and gas.

What Actually Happens When Your RSUs Vest

Let’s clear up the biggest point of confusion first. The grant date is when your company promises you shares. That day means nothing for taxes. The vesting date is when those shares actually become yours. That’s the day the IRS cares about.

When your RSUs vest, the total value of those vested shares gets treated as ordinary income. Think of it like a cash bonus. Your company calculates the fair market value on that vesting date.

Then they report that amount as RSU income (which is a type of supplemental income). You’ll see it on your W-2.

Most companies use a method called “sell to cover.” They automatically sell a chunk of your shares right at vesting. That sale covers your tax withholding for federal income taxes and other payroll taxes. The remaining shares land in your brokerage account.

Simple, right? But here’s the trap.

“A lot of equity holders mess this up,” says an equity compensation expert. “They think that just because their company automatically withholds some shares at vesting, they’re all set with the IRS. But here’s the thing—that standard withholding is usually based on lower tax rates.

“If you’re a high earner, it often doesn’t come close to what you actually owe. So come tax season, you could be staring at a pretty unwelcome bill.”

Why the Standard 22% Withholding May Not Be Enough

The IRS treats RSU withholding like a bonus. The flat federal rate is 22%. That works fine if your tax bracket is 22% or lower. But what if you sit in the 24%, 32%, or 35% bracket? You’ll owe ordinary income tax on the difference come tax time.

Let’s run a real example. You have a big vesting worth $50,000. Your company withholds 22% or $11,000. But your actual bracket is 32%. You owe $16,000. That leaves a $5,000 gap when you file taxes.

We’ve seen people get crushed by this surprise. One client owed an extra $12,000 because they didn’t plan ahead. So what can you do? Make estimated payments to the IRS each quarter. That penalty is avoidable.

A good rule of thumb: set aside an extra 10% to 15% of each vesting in a separate savings account.

How Are RSUs Taxed When Sold?

Now we answer the core question: how are RSUs taxed when sold? The answer depends entirely on what the stock price does after the vesting date. You already paid ordinary income tax on the value at vesting.

That value becomes your cost basis. Cost basis is simply the fair market value (or fair market for short) of the shares on the vesting day.

Think of cost basis as your purchase price for capital gains purposes. When you sell shares later, you only pay tax on the difference between that sale price and the cost basis. That difference is either a taxable gain or a capital loss.

The tax treatment changes based on your timing. Let’s break it into two clear scenarios.

When the Stock Price Goes Up (Taxable Gain)

Say your shares’ fair market value at vesting was $50 each. Six months later, you sell at $70 each. That $20 difference is a capital gain. You owe tax on that $20 gain per share, not on the full $70. Many people misunderstand this and overpay. Don’t be one of them.

When the Stock Price Goes Down (Capital Loss)

Prices move down too. Imagine the same $50 vesting price but you sell later at $40 per share. That $10 drop is a capital loss.

Losses can offset other gains. If your total losses exceed gains, you can deduct up to $3,000 against your regular taxable income each year. The rest carries forward.

A quick note: RSUs are taxed differently depending on the sale. But the RSU taxation rules are consistent. Learn them once and save money for years.

Short-Term vs. Long-Term Capital Gains: Why Timing Your Sale Matters

The clock starts ticking at the vesting date, not the grant date. That distinction makes all the difference for your capital gains tax rate. Hold the shares for one year or less and you face short-term capital gains rates.

Wait more than a year, and you get the much lower long-term capital gains rates.

Short-term gains get taxed like your regular paycheck. That means ordinary income taxes at your top tax rate. For a high earner, that could be 32% or 37%. That’s an “ouch” right there! Long-term capital gains rates run at 0%, 15%, or 20%. That gap is huge.

Here’s a concrete numbers example. You have a $10,000 gain on your remaining shares after vesting. Sell within one year at a 32% bracket. You owe $3,200. Wait 13 months and assume a 15% long-term rate. You owe $1,500.

That’s a $1,700 difference for doing nothing but waiting. (One more scenario: sell immediately at vesting. There’s no gain. There’s not any tax on the sale at all. That’s a clean exit strategy.)

Selling Within One Year (Short-Term)

Short term means 365 days or fewer from the vesting date. Your gain gets added to your total income. This can push you into an even higher bracket. We see people do this when they need cash fast. Just know the cost.

Holding More Than a Year (Long-Term)

The vesting schedule of your RSUs might give you multiple batches. Each batch has its own clock. Track each vesting period separately and use a simple spreadsheet. That way, you know exactly when each share turns “long term.”

Two Tax Traps That Can Quietly Cost You More

Most people mess up equity compensation at tax season in one of two ways. Both are easy to fix once you know about them. Let’s walk through each trap so you can avoid them.

The 1099-B Double Taxation Problem

You sell some RSU shares. Your brokerage sends a Form 1099-B. That form reports the sale proceeds. Here’s the dirty secret: Many brokers show a cost basis of $0 on that form.

If you don’t fix it, the IRS thinks you paid nothing for those shares. They’ll tax you on the full sale amount.

But you already paid ordinary income tax on the fair market value at vesting. That means you get double taxed on the same money.

Fix this by reporting the correct cost basis on Schedule D. Use the vesting date FMV as your true cost basis. This isn’t optional. It’s the difference between paying what you owe and paying twice.

The Wash Sale Rule and RSU Vestings

Here’s a sneaky one. You sell RSU shares at a capital loss to lower your tax bill. Great move! But then, within 30 days before or after that sale, you buy company stock again. That could be through a new RSU vesting or an employee stock purchase plan (ESPP).

That triggers the wash sale rule.

The IRS says you can’t claim that loss. It gets added to the cost basis of the new shares instead. So your intended tax savings vanish.

Plan your sales around your vesting calendar. If a vesting lands inside that 30 day window, wait to sell your losing positions until after the window closes. This is an easy adjustment that protects your taxable income reduction.

RSU Tax Strategies Worth Knowing Before Your Next Vesting

You made it through the technical stuff. Now for the payoff. These three moves turn knowledge into real savings. Each strategy works best for a specific financial situation. Pick the one that fits your goals.

Diversify After Vesting

Holding too much company stock is risky. Imagine 40% of your net worth tied to one employer. A bad quarter hits your job and your portfolio at the same time, and you can lose both.

Sell some RSUs right after vesting. Use that cash flow to build a balanced investment portfolio. Think low-cost index funds or a mix of sectors. Direct proceeds into retirement savings like a 401(k) or a Roth IRA.

Here’s a rule of thumb we use: keep single company stock below 10% of your total investments.

Time Large Vestings Around Your Tax Bracket

Your vesting schedule might drop a huge chunk of shares in one quarter. That single event could push your taxable income into a higher bracket for federal taxes.

What can you do? Talk to a tax professional before the vesting date. They might recommend accelerating deductions or deferring a bonus to another year.

One client deferred a $30,000 bonus by two weeks. It kept them in the 24% bracket instead of jumping to 32%. That saved $2,400.

Map out your RSU vesting dates at the start of every year, and that calendar becomes your best defense against unexpected tax bracket jumps.

Use Charitable Giving for High-Income Vesting Years

Got a massive RSU income year? Donate appreciated shares directly to a donor advised fund (DAF). You avoid paying capital gains tax on the appreciation.

Plus you get a charitable giving deduction that lowers your taxable income in that same calendar year.

Here’s a real example. You have $20,000 of RSU shares that grew from $10,000. Donate the shares. You skip capital gains tax on the $10,000 gain. You also deduct the full $20,000 if you itemize.

That double benefit softens the blow of a high income year. (Check with your tax professional first. Not everyone itemizes.)
