How do I manage the tax impact of RSU vesting?

Benefits & Compensationadvanced3 answers · 6 min readUpdated February 28, 2026

Quick Answer

RSU vesting creates ordinary income equal to the stock's fair market value on the vesting date. For a $150,000 salary with $50,000 in RSUs vesting, your effective tax rate on the RSUs could be 32-37% federal plus state taxes, requiring $16,000-$20,000+ in additional withholding or estimated payments.

How RSU vesting creates taxable income


When your RSUs vest, the IRS treats the fair market value of the shares as ordinary income, just like your salary. This income is subject to federal income tax, FICA taxes (if under the Social Security wage base), and state income tax. The challenge for high earners is that RSU income often pushes you into the highest tax brackets.


For 2026, if you're earning $200,000 in salary and have $80,000 in RSUs vest, that $80,000 is taxed at your marginal rate of 32% federal (plus 1.45% Medicare tax and state taxes). In California, your effective tax rate on those RSUs could exceed 45%.


Example: Managing a large RSU vesting event


Let's say you're a software engineer earning $180,000 base salary with $120,000 in RSUs vesting over the year ($30,000 per quarter):


Without planning:

  • Total income: $300,000
  • Federal tax bracket: 32% (income over $197,300 hits 32%)
  • Your RSU income of $120,000 is taxed at 32% federal + 1.45% Medicare = 33.45%
  • Plus California state tax of ~11% = 44.45% total
  • You owe approximately $53,340 in taxes on your RSU income alone

  • With proactive planning:

  • Increase 401(k) contribution to maximum $23,500 (reduces taxable income)
  • Make estimated quarterly tax payments of $13,335 each quarter
  • Consider timing discretionary stock sales to manage tax brackets
  • Review W-4 withholding after each vesting event

  • Key strategies for RSU tax management


  • Increase withholding immediately: Use Form W-4 line 4(c) to add extra withholding per paycheck. Calculate the annual RSU tax burden and divide by remaining paychecks.
  • Make quarterly estimated payments: If your employer's supplemental withholding rate (22%) is less than your marginal rate, make quarterly payments using Form 1040ES.
  • Maximize pre-tax deferrals: Contribute the maximum to your 401(k), HSA, and any other pre-tax accounts to reduce your taxable income base.
  • Time your stock sales: If you sell RSU shares immediately upon vesting, you minimize additional capital gains. If you hold them, plan the sale timing around your overall tax situation.
  • Consider state tax implications: Some states don't tax stock compensation, while others like California have rates exceeding 13%. This can influence timing decisions if you're relocating.

  • What happens if you don't plan ahead


    Many high earners get caught off-guard by RSU taxation. Your employer typically withholds at the supplemental rate of 22% federal, but if you're in the 32% or 37% bracket, this creates a shortfall. On $100,000 in RSU income:


  • Employer withholds: $22,000 (22%)
  • Actual tax owed (37% bracket): $37,000+
  • Shortfall: $15,000+

  • This leads to underpayment penalties and a large tax bill at filing time.


    What you should do


    1. Calculate your expected RSU income for the year: Review your equity compensation agreement to understand vesting schedules

    2. Determine your marginal tax rate: Use our paycheck calculator to understand where additional income will be taxed

    3. Adjust withholding or make estimated payments: Ensure you're withholding at your actual marginal rate, not the default 22%

    4. Review quarterly: RSU values fluctuate, so reassess your tax planning each quarter as shares vest

    Key takeaway: RSU vesting creates ordinary income taxed at your highest marginal rate. For high earners, this often means 35-50%+ total tax rates, requiring proactive withholding adjustments or estimated payments to avoid underpayment penalties.

    Key Takeaway: RSU vesting is taxed as ordinary income at your marginal rate, often 35-50% total for high earners, requiring proactive withholding adjustments to avoid underpayment penalties.

    Understanding RSU taxation basics


    When your RSUs vest, you immediately owe income tax on the full value of the shares, even if you don't sell them. This is different from stock options, where you only pay tax when you exercise and sell.


    Example for a typical employee


    If you earn $85,000 salary and have $15,000 in RSUs vest this year:

  • Your total taxable income becomes $100,000
  • The $15,000 RSU income is taxed at your marginal rate (22% federal in 2026)
  • You'll owe approximately $3,300 in federal taxes on the RSU income
  • Your employer typically withholds 22% ($3,300) automatically

  • Simple planning steps


  • Check your pay stub after vesting: Verify that taxes were withheld on the RSU income
  • Update your W-4 if needed: If you have large vesting events coming, increase withholding
  • Don't panic about the tax bill: Unlike bonuses, most employers handle RSU withholding correctly
  • Consider selling immediately: Many financial advisors recommend selling RSU shares upon vesting to avoid additional investment risk

  • Key takeaway: For most employees earning under $100,000, RSU taxation is straightforward—the income is taxed like a bonus at your regular tax rate, with proper withholding handled by your employer.

    Employees nearing retirement who need to coordinate RSU vesting with retirement planning and potential lower income years

    RSU timing strategies for pre-retirees


    If you're within 5 years of retirement, RSU vesting timing becomes crucial for tax planning. You may want to accelerate or defer vesting to align with lower-income retirement years.


    Consider your retirement income trajectory


    Many pre-retirees will drop from a $120,000+ working income to $60,000-80,000 in retirement income. This creates planning opportunities:


  • Defer RSU vesting if possible: Some companies allow you to defer vesting dates
  • Time your retirement: If you have significant unvested RSUs, consider working part-time to stay employed during vesting
  • Coordinate with 401(k) distributions: Balance RSU income with retirement account withdrawals to manage tax brackets

  • Medicare and Social Security considerations


    RSU income in the year you apply for Medicare can affect your premiums through IRMAA (Income-Related Monthly Adjustment Amount). If your income including RSUs exceeds $103,000 (single) or $206,000 (married), you'll pay higher Medicare Part B premiums.


    Similarly, if you're collecting Social Security while working, RSU income counts toward the earnings test limits.


    Estate planning implications


    Unvested RSUs typically don't transfer to beneficiaries, so coordinate with your estate planning attorney about timing.


    Key takeaway: Pre-retirees should coordinate RSU vesting with retirement timing to potentially capture the income in lower-tax retirement years, while considering Medicare premium impacts.
