RSU Tax Strategies for Tech Workers: 2026 Guide
Your RSUs just vested. 500 shares dropped into your brokerage account. Then you look at your pay stub — the company withheld 22% for taxes, and you realize that's nowhere near enough.
If you're a tech worker at Google, Meta, NVIDIA, Apple, or any public company paying in restricted stock units, you're about to find out why RSU tax planning is the most expensive surprise in your compensation package — not because you're financially unsophisticated, but because RSU tax rules are genuinely counterintuitive and nobody in HR walks you through them.
This RSU tax guide covers how RSUs are actually taxed in 2026, the withholding trap that blindsides nearly everyone, and nine concrete RSU tax strategies to reduce what you owe.
How RSUs Are Actually Taxed
RSUs (Restricted Stock Units) are taxed twice:
At vesting — as ordinary income. The full fair market value of the shares on the vest date is added to your W-2 wages. It's taxed exactly like your base salary — federal, state, Social Security (up to the wage base), and Medicare all apply. See IRS Publication 525 for the official treatment.1
At sale — as capital gains or losses. Any change in price between vest and sale is taxed as capital gains: short-term rates if you held less than a year, long-term rates if you held more than a year.
Example: 500 shares of NVDA vest at $150/share. The $75,000 vest value is taxed as ordinary income immediately. You hold for six months, then sell at $180/share. The $15,000 gain ($30 × 500) is taxed as short-term capital gains — meaning at your ordinary income rate, not the lower long-term rate.
Long-term capital gains rates in 2026 cap at 23.8% (20% long-term rate + 3.8% Net Investment Income Tax) for high earners.3 Short-term rates can hit 37%. The gap is where most of the RSU tax savings live.
The 22% Withholding Trap
Here's where most tech workers get wrecked.
Your employer treats RSU vests as supplemental wages, and the IRS default withholding rate for supplemental wages is 22%.2 That sounds fine if you earn $100K. It's a disaster if you earn $400K+ plus RSUs.
Do the math on a realistic Bay Area engineer:
Base salary: $220,000
RSUs vesting in 2026: $300,000
Total comp: $520,000 — firmly in the 35% federal bracket (the top 37% bracket starts at $626,350 married filing jointly in 2026)
Your employer withholds 22% of the $300K RSU vest — that's $66,000. Your actual federal tax on that $300K is closer to 35% — $105,000.
Federal shortfall: $39,000. Before California's 13.3% state income tax ($39,900 more).
You owe $78,900 beyond what your company withheld. If you didn't set it aside, you're writing a check to the IRS in April.
The RSU tax fix — one of three options:
Adjust your W-4 to request additional federal withholding from each paycheck
Make quarterly estimated payments to the IRS (Form 1040-ES) and your state
Set the shortfall aside immediately when shares vest — park it in a HYSA and don't touch it until tax time
Most financial advisors recommend option 3 because you earn interest on the tax reserve rather than front-loading it into payroll.
9 Strategies to Reduce Your RSU Tax Bill in 2026
1. Max Out Pre-Tax Retirement Accounts
Every dollar you push into a pre-tax 401(k) reduces your taxable ordinary income — which is exactly how your RSUs are taxed. This is the single biggest lever for reducing your RSU tax burden.
2026 contribution limits:
Pre-tax 401(k): $24,500 (+$8,000 catch-up contribution if you're 50 or older)
HSA (if on a high-deductible health plan): $4,400 self / $8,750 family
Mega backdoor Roth: up to $70,000 total 401(k) contributions if your plan supports after-tax contributions with in-service conversions4
Stacking all of these in a vest-heavy year can knock $30,000+ off your taxable income — roughly $10,500 in RSU tax savings at a 35% marginal rate.

2. Time Your Sales for Long-Term Capital Gains
Your vest-price basis is already taxed as ordinary income — that's locked in. But any gain above the vest price is taxed as capital gains, and the rate depends on how long you hold.
Held less than 1 year after vest: short-term capital gains = ordinary income rate (up to 37%)
Held more than 1 year after vest: long-term capital gains = 15% or 20% federal (+3.8% NIIT for high earners)
The catch: this RSU tax strategy only makes sense if you actually want more concentration in your employer's stock.
For most tech workers already overexposed to a single company, the better move is to sell at vest and diversify — accepting the short-term treatment on the minimal gain (usually pennies) rather than holding for a tax break you'll never fully capture. Concentration risk is the silent killer of tech wealth. A 15% tax discount doesn't make up for a 60% stock drop.
3. Tax-Loss Harvesting
If you sell RSU shares at a gain and have other investments sitting at a loss, realize those losses in the same year to offset the gains.
Capital losses offset capital gains without limit
Excess losses offset up to $3,000 of ordinary income per year
Remaining losses carry forward indefinitely
Watch the wash-sale rule: don't repurchase the same (or "substantially identical") security within 30 days before or after the loss sale, or the IRS disallows the loss. You can sidestep the rule by buying a similar-but-not-identical ETF for the 30-day window.
4. Use a Donor-Advised Fund (DAF) for Charitable Giving
If you give to charity anyway, give appreciated RSU shares instead of cash. You get:
An itemized deduction equal to the full fair market value of the shares (not your basis)
No capital gains tax on the appreciation
The ability to bunch multiple years of giving into one high-income year to exceed the standard deduction threshold
A donor-advised fund lets you front-load a big deduction in a heavy vest year while distributing grants to charities over time. For someone with a $300K vest in the 35% bracket, donating $20K of appreciated shares saves roughly $9,000 in federal RSU tax versus donating cash after selling.
5. Leverage Nonqualified Deferred Compensation (NQDC) Plans
Larger tech employers — Meta, Google, NVIDIA, Apple, Microsoft — often offer NQDC plans that let you defer a portion of base salary or cash bonus into future years. You can't defer the RSU income itself, but deferring other compensation in a heavy vest year pushes that income into a future, lower-income year.
The risk: NQDC dollars sit on your employer's balance sheet as an unsecured creditor claim. If the company goes bankrupt, you stand in line with other creditors. Not a real concern for Apple or Microsoft. Potentially one for a pre-IPO startup.
6. Phased Selling + Direct Indexing
Instead of dumping all your vested shares at once, sell on a pre-committed schedule aligned with your vesting events. Then reinvest the proceeds into a direct indexing strategy — where you hold the individual stocks that make up an index like the S&P 500 instead of the index fund itself.
Why direct indexing? Because it generates hundreds of individual tax lots. Whenever any one stock drops, you can harvest the loss to offset future RSU gains while maintaining the same market exposure. It's the most tax-efficient way to diversify a concentrated RSU position, and it compounds every year you hold.

7. Use the New 2026 SALT Deduction Cap ($40,000)
This is the RSU tax angle nobody has caught up to yet.
The State and Local Tax (SALT) deduction cap was stuck at $10,000 from 2018 through 2025. For 2026, it's been raised to $40,000. That's a massive deal if you live in California, New York, or New Jersey and own property.
For a Bay Area engineer paying $15K in property taxes and $25K+ in state income tax, you can now deduct the full $40K — up from $10K before. That's a $30,000 larger itemized deduction, worth over $10,000 in federal tax savings at a 35% rate.
Bunching property tax payments into vest-heavy years can amplify this further. Talk to a CPA before assuming you qualify — there are phase-outs at very high incomes.
8. State Tax Planning and Relocation
California taxes RSU income at up to 13.3%. If you're considering moving to Texas, Florida, Washington, or Nevada — all no-income-tax states — the timing relative to your vest schedule matters enormously.
The catch: California does not let go easily. The Franchise Tax Board will pursue its share of RSU income earned while you were a California resident, even if you've already moved. Work with a CPA who has handled California exit audits. Clean documentation of your move date, new residency, and where work was performed is critical.
Moving the week before a major vest can save you six figures in RSU tax. Moving the week after saves nothing.
9. Shift Discretionary Income Away from Vest-Heavy Years
If you have any control over when you earn income — consulting, advisory fees, exercising NSOs, ESPP sales, real estate transactions — push those events out of years with heavy RSU vests. Every dollar of non-RSU income you defer reduces your marginal rate on the RSU income.
The inverse is also true: if you know a light vest year is coming (your grant schedule tapers, or you're between refresh grants), that's the year to exercise options or realize other large gains.

FAQ
How are RSUs taxed when they vest?
RSUs are taxed as ordinary W-2 income at the fair market value of the shares on the vest date. That amount is added to your wages and subject to federal income tax, state income tax, Social Security (up to the wage base), and Medicare. Your employer withholds a default 22% for federal taxes, which is usually not enough for high earners.
Why does my employer only withhold 22% on my RSUs?
Because the IRS sets 22% as the default withholding rate for supplemental wages, which includes RSUs, bonuses, and commissions. It's a one-size-fits-none rate. If your marginal federal tax rate is higher than 22% — which is true for anyone earning over roughly $103K single or $206K married — you'll owe additional RSU tax when you file. You can request additional withholding on Form W-4 or make quarterly estimated payments.
Should I sell my RSUs as soon as they vest?
For most tech workers, yes. The vest-price basis is already taxed as ordinary income — holding doesn't save you any tax on that portion. Selling immediately removes concentration risk in your employer's stock and frees you to diversify. The small gain between vest and sale (if any) is usually not worth the added risk of holding a single stock.
Can I avoid RSU taxes entirely?
No. RSU tax at vest is non-negotiable — the IRS treats vested shares as ordinary wages the moment they transfer to you. You can only reduce the amount you pay by lowering your taxable income through pre-tax retirement accounts, HSAs, charitable giving via a DAF, timing decisions, and state-of-residence planning.
What's the biggest RSU tax mistake tech workers make?
Not setting aside the tax shortfall. The 22% withholding looks like a complete tax payment on your pay stub, so workers assume they're square with the IRS until April — then get hit with a five-figure RSU tax bill they didn't plan for. The fix: the moment shares vest, move the withholding gap into a HYSA and leave it alone until taxes come due.
The Bottom Line
RSU tax planning rewards discipline and punishes passivity. The tech workers who keep the most of their equity are the ones who:
Know their marginal tax rate before the year starts
Set aside the 22% withholding gap the day shares vest
Max out pre-tax 401(k), HSA, and mega backdoor Roth in vest-heavy years
Sell at vest and diversify instead of holding for concentration
Use the new $40K SALT cap, DAFs, and direct indexing to compound RSU tax savings year over year
