Amazon RSU Tax Planning: What AMZN Employees Need to Know (2026)

Amazon's equity compensation structure is deliberately unusual. Most tech companies vest RSUs evenly — 25% per year. Amazon doesn't. Its standard schedule front-loads nothing and back-loads everything: 5% in year one, 15% in year two, and 40% in each of years three and four. That design is intentional retention engineering. The tax consequence is a sudden, large income spike in years three and four that most employees are completely unprepared for. This guide covers the withholding math, Washington state's unique tax treatment, concentration planning, and the planning moves that matter most for Amazon employees.

How Amazon RSUs work

Amazon issues restricted stock units on a non-standard vesting schedule that differs materially from every other major tech employer. Understanding the mechanics is the first step to managing the tax consequences:

• The 5-15-40-40 vest schedule: Amazon RSUs vest over four years on a back-loaded schedule — 5% of the total grant in year one, 15% in year two, 40% in year three, and 40% in year four.¹ This means 80% of your total grant value delivers in the final two years. At most other large tech employers (Google, Microsoft, Meta), the schedule is a flat 25% per year with quarterly vesting throughout.
• Vest dates: Vesting occurs semi-annually in years one and two (typically around May and November) and quarterly in years three and four (typically around February, May, August, and November). The exact dates are stated in your grant agreement — check the actual document rather than relying on estimates.
• Tax event at vest: Like all RSUs, Amazon RSUs are not taxable when granted. They become taxable when they vest, at the fair market value of AMZN shares on the vesting date, under IRC § 83(a).² The vest-day FMV is ordinary income — not capital gain — and appears in Box 1 and Box 12 (Code V) of your W-2.
• Sell-to-cover withholding: Amazon typically withholds taxes by selling a portion of your vesting shares at the vest-day price. The company sells enough shares to cover the federal 22% supplemental rate, Medicare (1.45%), and any applicable state income tax. The sale proceeds go to the IRS and state; the remaining shares are deposited into your brokerage account. This sell-to-cover transaction appears on your year-end 1099-B with a cost basis equal to the vest-day FMV, typically resulting in a $0 capital gain (or a small rounding difference).
• No ESPP: Amazon does not offer an employee stock purchase plan (ESPP) with a purchase discount under IRC § 423.³ There is a Direct Stock Purchase Plan (DSPP) through Computershare that allows you to buy AMZN shares at market price, but this is not a discounted ESPP and has no preferential tax treatment. Unlike Nvidia, Google, or Microsoft employees, Amazon employees cannot benefit from ESPP qualifying-disposition planning.
• RSU-to-cash election (2026): Amazon added a cash conversion option in 2026. Eligible employees can elect during an annual enrollment window to receive 75% of their RSU vesting as shares and 25% as a cash equivalent, based on a fixed conversion price announced by Amazon. The cash portion is treated identically to RSU income — ordinary income at delivery — so it doesn't change the tax character of your compensation. It does mean some employees receive cash directly rather than needing to sell shares to cover concentration or liquidity needs.

The year-3 income spike and the withholding gap

The single most important thing to understand about Amazon RSU taxation is the income asymmetry between year one and year three. The federal supplemental withholding rate is 22% on all RSU vest income, regardless of how large the vest is.⁴ That rate doesn't change when your vesting income triples. Your effective marginal tax rate does.

Here is what the withholding math looks like for a representative Seattle-based SDE III (L6) with a $600,000 four-year grant and $214,000 base salary:

The gap in year three and four is driven entirely by the gap between the 22% withholding rate and the 35% federal marginal rate on income at that level. In Washington state, there is no state income tax on ordinary income — so Amazon employees in Seattle face only the federal gap. Amazon employees in California offices face an additional 9.3–13.3% California gap on top of the federal shortfall, which can push the total underpayment above $60,000 in a high-vest year.

The fix: Adjust your W-4 Step 4(c) starting no later than Q1 of your second year, or make quarterly estimated payments via EFTPS before each vest. The RSU W-4 withholding guide and estimated tax guide walk through both approaches with specific calculation steps.

Note: year-four vesting often coincides with RSU refresh grants from prior performance cycles beginning to vest simultaneously. Total vesting income in year four can exceed the year-three number, potentially pushing into the 37% federal bracket (above $626,350 for single filers in 2026).⁴

Washington state tax: the good news and the catch

Amazon's Seattle headquarters means most Amazon employees are Washington residents. Washington has no state income tax — a significant benefit for Amazon RSU holders that is frequently underappreciated:

• No income tax on RSU vesting income: Unlike California (13.3% top rate) or New York (10.9%), Washington does not tax ordinary income. Your RSU vest income is subject only to federal income tax and FICA. An Amazon employee in Seattle with $240,000 of RSU vesting income saves up to $31,920 in state income tax compared to an equivalent employee in California.
• No income tax on salary: Washington also imposes no income tax on your $200,000+ base salary. The total state income tax savings vs. California can easily exceed $50,000–$70,000 per year at senior Amazon compensation levels.

However, Washington enacted a capital gains tax that adds complexity for Amazon employees who hold AMZN shares after vesting:

Washington's capital gains tax (2026)

Washington's capital gains tax was upheld by the state Supreme Court in 2023 and applies to long-term capital gains realized by Washington residents. For 2026, the structure is:⁵

• Annual deduction: Approximately $278,000 per return (inflation-indexed). Capital gains below this threshold are not taxed.
• 7% tier: Gains above the deduction, up to $1,000,000 above the deduction, are taxed at 7%.
• 9.9% tier: Gains above $1,000,000 above the deduction are taxed at 9.9% (a 2.9% surtax on top of the 7% base rate, enacted effective tax year 2025 via ESSB 5813).

This tax applies to capital gains only — not to ordinary income like RSU vesting income. Here is how it interacts with Amazon RSU planning:

• Selling AMZN immediately at vest: If you sell shares within days of vesting, there is essentially no capital gain (your cost basis is the vest-day FMV, and the stock hasn't moved meaningfully). No Washington capital gains tax applies. This is the simplest approach and eliminates WA cap gains exposure entirely.
• Holding AMZN shares 12+ months for LTCG treatment: If you hold vested shares for more than one year before selling, any appreciation above the vest-day FMV becomes a long-term capital gain. Federal LTCG rates are 0%, 15%, or 20% depending on income (plus 3.8% NIIT above $200,000/$250,000). Washington then taxes any gains above $278,000 at 7%–9.9%. For employees in the 20% federal LTCG bracket with WA gains above $278,000, the combined rate on capital gains is 23.8%–29.7% — still meaningfully lower than the 35–37% federal ordinary income rate, but no longer the "zero state tax" picture that applies to the vest event itself.

Amazon employees at other locations

If you work at Amazon offices outside Washington — in California, New York, Virginia, Texas, or elsewhere — your state tax picture differs significantly:

• California (AWS, Cupertino; Amazon, San Francisco; Amazon Alexa/Ring): California taxes all RSU vesting income at up to 13.3%, treats all capital gains as ordinary income (no LTCG rate), and applies allocation rules to RSUs granted while you were a California resident even if you've since moved. See the RSU state taxes guide for the FTB Publication 1100 workday-allocation formula.
• Virginia (HQ2, Arlington): Virginia income tax applies at up to 5.75% on RSU vesting income. Lower than California but still meaningful on $240,000 of year-three vesting (~$13,800). Virginia conforms to federal LTCG rates.
• Texas (Amazon, Austin): No state income tax and no capital gains tax. Texas Amazon employees face only the federal gap — the same effective position as Washington, except Texas has no capital gains tax at all.
• New York (Amazon NYC): New York City is the highest combined income tax environment for Amazon employees, with a state rate up to 10.9% and an additional NYC rate up to 3.876%. An NYC employee with $240,000 of RSU vesting in year three could face over $35,000 in state and city income tax above what's withheld — in addition to the federal gap.

AMZN concentration risk

The back-loaded vesting schedule creates a secondary problem beyond the withholding gap: concentration. By the time an Amazon employee finishes a four-year grant cycle, they've received 80% of their equity value in the final two years — and if they've held any of those shares (rather than selling at each vest), their AMZN position has grown rapidly while the rest of their financial plan may not have kept pace.

A typical SDE III at four years of tenure might hold:

• Vested shares from the current grant (years 3–4)
• Shares still vesting from prior performance cycle grants and refresh grants
• Unvested shares still subject to forfeiture if they leave

At AMZN price levels, the vested-share balance from a single 4-year grant cycle can represent $300,000–$600,000 in a single equity position. If an employee has been at Amazon for 6–8 years with multiple grant cycles and has sold minimally, the concentration can be substantially higher.

The standard rule of thumb is to actively plan around concentration when a single stock exceeds 15–25% of total investable net worth. Strategies include:

• Systematic sell-at-vest: Selling all or most shares immediately at each vest event eliminates both capital gains risk and concentration growth. The cost basis equals the vest FMV, so no capital gain accrues. For Washington employees, this also eliminates WA capital gains tax entirely.
• 10b5-1 plan for insiders: Amazon employees with access to material non-public information — which typically includes anyone at L7+ or in certain functional roles — must execute AMZN sales through a pre-established 10b5-1 plan or during designated open trading windows. The SEC's 2023 rule amendments require a 90-day cooling-off period (120 days for officers) after plan adoption before the first trade, so setup must happen well in advance of when you need to sell.
• Donor-advised fund (DAF) donation: For Amazon employees who make charitable contributions, donating long-term appreciated AMZN shares directly to a DAF generates a full fair-market-value charitable deduction while eliminating the capital gains tax on the donated shares. The higher the combined federal + WA cap gains rate, the greater the tax savings from in-kind donation vs. selling and donating cash. See the charitable giving with appreciated stock guide.
• Staggered sales for WA cap gains management: If you have substantial unrealized gains, spreading sales across multiple years to keep annual realized gains near the $278,000 WA deduction reduces or eliminates the Washington capital gains tax bite year by year.

Year-end planning for Amazon employees

Because Amazon's heaviest vesting lands in years three and four, and because year-end is when several planning elections must be made, the final calendar quarter is the most important planning window for most Amazon RSU holders:

1. Maximize 401(k) contributions: Pre-tax 401(k) contributions directly reduce your taxable W-2 income. The 2026 elective deferral limit is $24,500 ($32,500 for ages 50–59 and 64+; $36,000 for ages 60–63 via the SECURE 2.0 super catch-up).⁶ Every dollar deferred at a 35–37% marginal rate saves 35–37 cents in federal tax. Amazon's 401(k) includes employer matching — confirm the match schedule to ensure you're not leaving matching dollars on the table.
2. Mega backdoor Roth: Depending on your 401(k) plan design, after-tax contributions beyond the standard deferral limit may be allowed, up to the 2026 § 415(c) total cap of $72,000.⁶ After-tax contributions converted to Roth (the "mega backdoor Roth") permanently shelter future growth from tax. At Amazon income levels, this is one of the few tax shelters available that doesn't require holding more AMZN stock. See the mega backdoor Roth guide.
3. NQDC election deadline: If Amazon offers a non-qualified deferred compensation (NQDC) plan, elections to defer 2027 income must typically be made before December 31, 2026. Deferring a portion of your year-four RSU vesting income into an NQDC can shift it to a future year when your marginal rate may be lower (e.g., after you've left Amazon or retired). See the NQDC guide for the 409A rules and timing requirements.
4. Q4 estimated tax check: After each vest event, recalculate your projected year-end federal tax liability vs. withholding-to-date. If you're short, make an additional EFTPS payment before January 15 of the following year to close the gap under the safe harbor rules and avoid underpayment penalties.
5. AMZN shares: sell, hold, or donate decision: Before December 31, decide whether any holdings have appreciated enough to make charitable donation or loss harvesting worthwhile. Long-term appreciated AMZN shares donated to a DAF generate a deduction at FMV and eliminate capital gains. Unrealized losses elsewhere in your portfolio can be harvested to offset gains — but watch the wash-sale rule if Amazon vest dates land within 30 days of the loss harvest.
6. 2027 10b5-1 plan setup window: If you want a 10b5-1 plan in effect for 2027 sales, you must adopt it during an open trading window in Q3–Q4 2026, accounting for the 90–120 day cooling-off period. See the 10b5-1 trading plan guide for the 2023 SEC rule requirements.

The "golden handcuffs" effect of years 3 and 4

The 5-15-40-40 schedule is not a coincidence — it is a deliberate retention mechanism. An Amazon employee who has completed year two has delivered 20% of their grant value and has 80% still outstanding. The financial cost of leaving at that point is enormous.

But the golden handcuffs calculation requires getting the after-tax math right. The "walk-away cost" is not the face value of the unvested grant — it is the unvested grant multiplied by your after-tax retention rate. If you're in the 35% federal bracket with no state income tax (WA), keeping an extra $240,000 of year-three vesting is worth $240,000 × (1 − 35%) = $156,000 after federal tax. That is still a large number, but it is the right number to use when evaluating a competing offer.

Competing employers that offer front-loaded vesting schedules or large signing bonuses structured to replace year-three/four Amazon income are compensating specifically for this dynamic. The golden handcuffs guide walks through the after-tax walkaway calculation in detail.

When Amazon employees need an equity specialist

Not every Amazon RSU question requires a specialist, but several situations substantially benefit from one:

• Approaching your year-three cliff: If year-three vesting will materially exceed anything you've seen in prior years, W-4 and estimated-tax planning needs to be done before the first vest of the year — not after you file in April and see a large balance due.
• AMZN position exceeds 20–25% of net worth: The combination of a back-loaded schedule, appreciation in AMZN, and a tendency to hold rather than sell can accumulate a dangerously concentrated position. An advisor can model a tax-efficient diversification path that accounts for WA cap gains, the annual deduction, and your overall financial plan.
• Considering leaving Amazon: The walkaway-cost calculation involves vested shares, unvested shares, state tax treatment of the transition, any ISO 90-day windows from earlier employers, and whether your unvested grants at Amazon include any double-trigger acceleration. Getting the full picture before resigning is worth doing.
• Moving into or out of Washington: Establishing or abandoning WA residency involves timing considerations around vest dates, unrealized gains, and California allocation rules if you've held prior CA Amazon employment. The planning window is often narrow and the stakes are high.
• Pre-IPO equity from prior startups: Amazon employees who held ISOs or QSBS at a prior employer and still have decisions to make — exercise, hold-to-five-year, or sell — need that analysis done in the context of Amazon's compensation income, which will affect AMT headroom and marginal rate calculations.
