RSU Vesting Tax Strategy for Tech Employees

You Got a $200K RSU Grant Vesting Over 4 Years — Your First Vest Is Coming

A tech company granted you 500 RSUs at $400/share = $200,000 total value, vesting 25% per year over four years. In 12 months, 125 RSUs vest. If the stock is still at $400, that's $50,000 in RSUs hitting your paycheck.

Here's what surprises most tech employees: your company will withhold 22% flat on that $50,000 — which is $11,000. But if your total W-2 income is $180,000 (salary + RSUs), your marginal bracket is 32%. The difference — that extra 10% or $5,000 — is money you'll owe in April unless you adjust.

How RSU Vesting Creates Ordinary Income

RSUs vest when you meet a time or performance condition. At the moment of vesting, the IRS treats the full fair market value of the shares as ordinary income — the same as wages. It appears on your W-2 in Box 1.

Example: 125 RSUs vest when the stock price is $420/share.

• Income recognized: 125 × $420 = $52,500
• This $52,500 is added to your W-2 income
• Your cost basis in the shares is now $52,500 (not $0)

If you later sell those shares at $450, you have a $3,750 capital gain ($450 - $420 = $30/share × 125 shares) — not a $56,250 gain. The ordinary income tax was already paid at vesting.

The 22% Withholding Rate Problem

The IRS requires employers to withhold on supplemental wages (bonuses, RSUs) at a flat 22% for amounts under $1 million. This is a minimum withholding floor, not the rate you actually owe.

At a $180,000 total W-2 (including RSU income), your marginal bracket for 2026 is 24% on income between $100,525 and $191,950 for single filers. On that $52,500 RSU vest:

If your total income is higher — say $250,000 with RSUs — you're in the 32% bracket. The withholding gap balloons:

• 22% withheld on $52,500 = $11,550
• 32% actual rate = $16,800
• Gap: $5,250 — this appears as a balance due in April

Solution: File a new W-4 after each vest and add extra withholding in Step 4(c) to cover the gap. Or make a quarterly estimated tax payment in the same quarter the RSUs vest.

Sell-to-Cover vs Same-Day Sale vs Hold

Employers typically offer three options at vesting:

Sell-to-Cover The company automatically sells enough shares to cover the withholding tax. On 125 shares at $420 with 22% withholding: $52,500 × 22% = $11,550 owed. The company sells 27.5 shares ($11,550 ÷ $420 = 27.5, rounded to 28 shares) and deposits the rest (97 shares) in your brokerage account.

Result: you receive 97 shares with a $420/share cost basis. You own stock and have no immediate cash outlay.

Same-Day Sale (Cash Out) The company sells all 125 shares immediately and sends you the after-tax cash. At $420/share gross $52,500, minus 22% withholding $11,550, you receive $40,950 cash. No stock position to track, no future capital gains exposure.

Hold (No Sale) You pay the withholding tax from your regular paycheck or savings, and keep all 125 shares. Highest risk/reward: if the stock drops after vesting, you've already paid income tax on the higher value. But if it rises, your gains are taxed at the lower capital gains rate (0%, 15%, or 20%) rather than ordinary income rates.

The Hold Strategy's Hidden Tax Efficiency

Holding RSUs after vesting converts future appreciation from ordinary income to capital gains. The savings depend on how long you hold and how much the stock appreciates:

Year 1 after vesting: Stock rises from $420 to $480. You sell. Gain: $60/share × 97 shares = $5,820. Long-term capital gains rate (since you held over 1 year): 15% = $873 in tax.

Compare to if those same gains had been part of your RSU vesting income: $5,820 × 32% = $1,862 in ordinary income tax. Holding saves $989 in this example.

The hold strategy breaks down when companies underperform. An employee who held RSUs in a tech company that declined 50% paid full income tax at vesting on $420/share but now holds stock worth $210/share — a $210/share loss with no offset since the income tax can't be refunded.

Rule of thumb: Hold only if you'd buy the stock at today's price with your own money. If you wouldn't buy $52,500 worth of your company's stock on the open market today, sell at vesting and invest the proceeds in a diversified portfolio.

RSUs vs Stock Options: The Key Tax Difference

RSUs and non-qualified stock options (NQSOs) are both common tech compensation, but they're taxed differently.

With RSUs, you pay ordinary income tax when shares vest, regardless of whether you sell. You have no choice. If the stock is at $420 on vest date, $52,500 is taxable income.

With NQSOs, you pay ordinary income tax only when you exercise (buy) the options. If you have options with a $200 exercise price and the stock is at $420, exercising creates $220/share of ordinary income. You can choose when to exercise — spreading exercises across tax years to manage bracket exposure.

The tradeoff: NQSOs require you to spend money to exercise, and they expire (typically 10 years for employees, 90 days after termination). RSUs vest automatically and have no expiration or exercise cost.

For most tech employees, RSUs are simpler to manage. The calculator below handles the withholding gap calculation for any vest size, salary combination, and filing status.
