How Are RSUs Taxed in 2026?
Quick Answer: RSUs are taxed as ordinary income when they vest. The vest-date value becomes both your taxable wage and your cost basis.
RSUs feel like a gift. However, the IRS treats them as pay. When your shares vest, the full market value counts as ordinary income. As a result, it lands on your Form W-2 just like a bonus. For 2026, this income can push you into the top 37% federal bracket. Therefore, understanding the timeline matters a lot.
Many clients confuse vesting with selling. In fact, these are two separate tax events. First, vesting triggers ordinary income tax. Later, selling triggers capital gains or losses. The IRS explains this split in IRS Publication 525 on taxable income. Good RSU tax planning strategies manage both moments.
Why Withholding Often Falls Short
Most employers withhold 22% on supplemental wages. Yet high earners often owe 37%. Consequently, a gap appears at tax time. For example, say $500,000 in RSUs vest. Your company withholds $110,000. However, your true rate may demand $185,000. That leaves a $75,000 shortfall. Therefore, plan for extra estimated payments.
How Cost Basis Works at Vesting
Your cost basis equals the vest-date value. In other words, you already paid tax on that amount. Later gains are measured from that basis. Furthermore, holding shares over one year earns lower long-term capital gains rates. The IRS Topic 409 on capital gains confirms these holding-period rules.
Pro Tip: Set aside the gap between 22% withholding and your real rate. This avoids a shock at filing time.
How Does Tax-Lot Selection Lower RSU Taxes?
Quick Answer: Specific tax-lot selection lets you choose which shares to sell. Selling high-basis lots first minimizes your taxable gain.
Tax-lot selection is one of the most powerful RSU tax planning strategies. Each vesting date creates a separate lot with its own basis. Therefore, you can pick which lot to sell. Most brokers default to FIFO, meaning first-in, first-out. However, FIFO often sells your lowest-basis shares. As a result, you trigger the biggest gain. Instead, use specific identification.
Recently vested RSUs make the best starting point. Their basis equals current value. Consequently, selling them creates little or no gain. In contrast, older lots carry large embedded gains. This proactive tax strategy approach turns a routine sale into a savings event.
Comparing Lot Methods for 2026
The table below shows how method choice changes your tax. Assume you sell $100,000 of stock. The results differ sharply.
| Method | Shares Sold | Taxable Gain | Est. Tax |
|---|---|---|---|
| FIFO (oldest first) | Low-basis lot | $60,000 | ~$12,000 |
| Specific ID (high basis) | Recent vest | $5,000 | ~$1,000 |
| HIFO (highest cost) | Highest-basis lot | $3,000 | ~$600 |
Figures are illustrative estimates for 2026. Verify your actual rates at IRS.gov.
How to Elect Specific Identification
- Log in to your brokerage before placing the trade.
- Switch the cost-basis method from FIFO to specific ID.
- Pick the exact lots you want to sell by date.
- Confirm the lot selection on your trade confirmation.
How Does Capital Loss Harvesting Help RSU Holders?
Quick Answer: Loss harvesting sells losing positions to offset gains. Excess losses offset up to $3,000 of ordinary income yearly.
Loss harvesting pairs well with RSU sales. First, you sell a loss position. Then, that loss cancels out capital gains from your RSUs. Moreover, any leftover loss offsets up to $3,000 of ordinary income each year. Unused losses then carry forward indefinitely. The IRS capital gains and losses guidance explains this limit clearly.
High earners often hold diversified portfolios. Therefore, some positions sit at a loss each year. Selling them creates valuable tax losses. For example, imagine $40,000 of RSU gains and $40,000 of stock losses. As a result, your net taxable gain drops to zero. This is why many investors who also hold real estate coordinate all sales together.
Watch the Wash-Sale Rule
The wash-sale rule can block your loss. Specifically, you cannot rebuy the same security within 30 days. If you do, the IRS disallows the loss. Therefore, wait 31 days or buy a similar but not identical fund. This keeps your harvested loss valid.
A Worked Harvesting Example
Suppose you realize $80,000 in RSU gains. You also hold a tech fund down $50,000. First, you sell the fund. Next, your net gain falls to $30,000. Then, you reinvest in a similar fund after 31 days. Consequently, you stay invested while cutting your 2026 tax bill.
Did You Know? Carried-forward losses never expire. You can use them in future years to offset RSU gains.
How Do Retirement Accounts Reduce Your RSU Tax Bill?
Quick Answer: Maxing pre-tax retirement accounts lowers taxable income in high RSU years. The mega backdoor Roth adds even more room.
Retirement maximization is often the biggest lever. In a big vesting year, your income spikes. Therefore, pre-tax contributions offer strong value. For 2026, the 401(k) elective deferral limit is about $24,500. Please verify current limits at IRS.gov. These deferrals lower your taxable wages dollar for dollar.
The mega backdoor Roth is a powerful add-on. Some plans allow large after-tax contributions. Then you convert them to Roth. As a result, future growth becomes tax-free. The IRS 401(k) contribution limit rules describe the overall cap. Working with an ongoing tax advisory partner helps you time contributions well.
Stacking Multiple Accounts
High earners can stack several accounts. For instance, you might combine a 401(k), an HSA, and a backdoor Roth IRA. Furthermore, business owners can add a solo 401(k). This layering shelters more income during RSU years. Delaware business owners weighing an entity move can use our Delaware LLC vs S-Corp Tax Calculator to compare structures.
Charitable Giving With Appreciated Shares
Donating appreciated RSU shares offers a double benefit. First, you skip the capital gains tax. Second, you get a deduction at fair market value. Therefore, charitable giving fits well in big income years. A donor-advised fund can also spread the timing.
Can State Residency Planning Cut RSU Taxes?
Free Tax Write-Off FinderQuick Answer: Yes. Moving to a no-income-tax state before a major vesting event can save large sums on RSU income.
State taxes add a hidden layer to equity compensation. High-tax states like California and New York take a big cut. In contrast, states like Texas and Florida charge no state income tax. Therefore, residency is now a planning variable. However, states apply source rules to RSUs earned while working there. Consequently, you cannot avoid all state tax simply by moving.
Timing matters a great deal here. Many states tax RSU income based on where you worked during the vesting period. As a result, a late move may only shield future grants. Still, the savings can be large over time. The California Franchise Tax Board publishes detailed sourcing rules worth reviewing.
State Tax Exposure Comparison
| State | Top Rate | Tax on $500K RSU |
|---|---|---|
| California | ~13.3% | ~$66,500 |
| New York | ~10.9% | ~$54,500 |
| Texas / Florida | 0% | $0 |
Rates are approximate for 2026 and exclude federal tax. Verify with each state agency.
Making a Move Defensible
A residency move must be real. Therefore, change your driver’s license, voter registration, and home base. Furthermore, spend most of your year in the new state. High-tax states audit aggressively. As a result, strong documentation protects you.
When Should You Sell Your RSU Shares?
Quick Answer: Sell enough at vesting to cover taxes and reduce concentration. Hold strategic lots for long-term capital gains rates.
Timing your RSU sales takes discipline. Many clients fall into concentration risk. In other words, too much wealth sits in one stock. Therefore, selling at vesting reduces that risk. Since basis equals vest-date value, selling then creates little gain. This is a core piece of strong RSU tax planning strategies.
Executives also face blackout windows. During these periods, selling is restricted. Consequently, a 10b5-1 plan helps. This plan schedules sales in advance. As a result, you trade on a set calendar, not on emotion. The U.S. Securities and Exchange Commission governs these insider-trading rules.
Short-Term vs Long-Term Rates
Holding shares over one year earns lower rates. Specifically, long-term gains top out at 20% for high earners in 2026. Short-term gains, however, hit your full 37% rate. Therefore, patience can cut your rate nearly in half. Still, weigh this against concentration risk.
Watch the Net Investment Income Tax
High earners also face the 3.8% Net Investment Income Tax. It applies above $250,000 for joint filers. Therefore, large RSU gains can trigger it. Planning sales across two years may reduce this surtax. This is where guidance built for high earners and owners pays off.
Uncle Kam in Action: A Tech Executive With Concentrated RSUs
Here is a hypothetical example of how this works in practice.
The Scenario: Picture a software executive in a high-tax state. She holds $600,000 in RSUs across three vest dates. Two lots are old with large gains. One lot vested last month.
The Challenge: She needs $150,000 in cash. However, her broker defaults to FIFO. Therefore, a routine sale would trigger a huge gain. Meanwhile, her 22% withholding left a tax gap from vesting.
How Uncle Kam Would Approach It: First, we switch her to specific tax-lot identification. Then she sells the recently vested lot. Since basis equals current value, the gain is tiny. Next, we harvest a $40,000 loss from a losing fund. That loss offsets older gains she sells later. Furthermore, we max her 401(k) and add a mega backdoor Roth.
Illustrative Numbers: Selling the recent lot creates roughly $5,000 in gain instead of $90,000. As a result, she could save roughly $17,000 in capital gains tax. Adding retirement deferrals could lower her taxable income by another $24,500. Combined, these moves could save her tens of thousands for 2026. These are estimates, not promised outcomes.
This example is illustrative only. See real outcomes on our documented client results page.

Frequently Asked Questions
What is the cost basis of RSUs at vesting?
Your cost basis equals the share value on the vesting date. You already paid ordinary income tax on that amount. Therefore, future gains are measured from that basis.
How does the $3,000 capital loss limit work?
First, losses offset your capital gains without limit. Then, any extra loss offsets up to $3,000 of ordinary income yearly. Finally, unused losses carry forward to future years.
Can I avoid state tax by moving before vesting?
Partly. Many states tax RSU income based on where you worked during the grant period. Therefore, a move may only shield future grants. Still, the long-term savings can be large.
What is a mega backdoor Roth?
It lets you make large after-tax 401(k) contributions. Then you convert them to Roth. As a result, future growth becomes tax-free. However, your plan must allow this feature.
Should I sell RSUs right away or hold them?
Selling at vesting reduces concentration risk with little gain. However, holding over one year earns lower long-term rates. Therefore, balance both goals with a written plan.
