AMD RSU Tax Planning for AMD Employees (2026)

Advanced Micro Devices has gone from a company trading near its all-time lows in 2018 to one of the leading semiconductor stocks in the world, powered by EPYC server CPUs and Instinct MI300-series AI accelerators. For AMD employees who received RSU grants during or before this run-up, the result is significant equity wealth — and significant tax complexity. The 22% federal supplemental withholding rate is deeply mismatched with real marginal rates for most AMD employees in California, and long-tenured employees may hold AMD shares with very low cost basis. This guide covers the withholding gap, concentrated-AMD-stock risk, the ESPP, Austin-vs.-California state tax math, and the planning moves that matter most in 2026.

How AMD RSUs work

AMD issues restricted stock units under a standard four-year vesting schedule for most employees. Key mechanics:

• Vest schedule: AMD RSUs typically vest 25% after the first year (cliff), then 6.25% per quarter for years 2–4. Refresh grants and retention grants may have different structures. Verify your specific grant terms in your AMD equity portal or grant agreement.
• Tax event at vest: RSUs are not taxable at grant. Under IRC § 83(a), they become taxable when restrictions lapse at vest, at the fair market value of AMD shares on the vesting date.¹ That FMV amount is ordinary income subject to federal income tax, California income tax, and FICA.
• Sell-to-cover: AMD typically uses a sell-to-cover mechanism at each vest. A portion of the vesting shares is automatically sold to cover the 22% federal supplemental withholding plus Social Security (up to the $184,500 wage base²), Medicare, and applicable California supplemental withholding. The remaining shares are deposited to your Fidelity or other brokerage account. The sell-to-cover shares appear on your 1099-B with a cost basis equal to the vest-day FMV, so the capital gain or loss on those shares is near zero.
• Trading windows: AMD maintains quarterly blackout periods around earnings. Employees with access to material non-public information may only trade during open windows or under a pre-approved 10b5-1 plan. Open windows typically begin two trading days after AMD's quarterly report. Plan any sell or diversification activity around this schedule.

The withholding gap at AMD income levels

The federal supplemental withholding rate is 22% on the first $1,000,000 of supplemental wages from one employer in a calendar year, and 37% above that threshold.³ For most AMD employees, RSU vest income is withheld at 22%.

A worked example for a Senior Software Engineer in Santa Clara:

This excludes the 0.9% Additional Medicare Tax (applies above $200K single / $250K MFJ), bonus, ESPP gain, and California's separate supplemental withholding mechanics. Staff and principal engineers with larger grants face proportionally larger gaps. Use the RSU tax calculator to model your specific numbers.

The withholding gap by level — Santa Clara and Austin:

Texas has no state income tax, so Austin-based AMD employees only face the federal withholding gap (22% withheld vs. 37% real). California employees face the compounded shortfall. In both cases, the gap is real and accumulates across quarterly vests. The RSU W-4 withholding guide explains how to close it using W-4 Step 4(c) adjustments, and the estimated tax guide covers the quarterly safe-harbor math.

Concentrated AMD stock: the multi-year appreciation problem

AMD shares traded below $20 as recently as early 2019. By 2023 the stock exceeded $100 and has continued its run driven by EPYC data-center adoption and the MI300X AI accelerator competing directly with NVIDIA's H100 and B100 series. For AMD employees who received grants when the stock was at $5–$25 and didn't sell the shares at each vest, the result is a low-cost-basis position worth multiples of the original grant value.

The concentration risk that follows is structural:

• Employment correlation: If AMD's competitive position weakens — for example, NVIDIA defends its AI-accelerator market share, or x86 loses ground in data center to ARM-based chips — the same headwinds that compress AMD's stock price are likely to slow hiring, freeze refreshes, and shrink bonuses. Your financial capital and your human capital are exposed to the same semiconductor-market factor.
• Insider trading constraints: Employees with MNPI cannot sell AMD shares during blackout windows. If you need liquidity during a closed window — to cover a large quarterly tax bill, fund a real estate purchase, or respond to a market move — there is no path to sell unless you have a pre-established 10b5-1 plan. Setting one up requires an open window and takes 90–120 days to activate. See below.
• California's no-LTCG-preference rule: For California residents, holding AMD shares for 12 months to qualify for the federal long-term capital gains rate provides no state tax savings. California taxes all capital gains as ordinary income at up to 13.3%, regardless of holding period. Every dollar of AMD appreciation you hold unnecessarily remains exposed to a combined federal + California rate of up to 23.8% + 13.3% = 37.1% on exit — or more if you're still in the 37% federal bracket at disposition.

The 10b5-1 solution for AMD employees

A Rule 10b5-1 trading plan lets you pre-commit to a specific sell schedule — by date, price trigger, or quantity — during a period when you don't possess MNPI. Once adopted, the plan executes automatically, including during otherwise-closed blackout windows.

After the SEC's December 2022 amendments, new plans require a 90-day cooling-off period for non-officer employees or 120 days for directors and executive officers before the first trade executes.⁴ You must establish the plan well before you need liquidity — not in response to an approaching blackout.

A well-designed 10b5-1 plan for an AMD employee typically:

• Times sell orders to execute shortly after each quarterly vest event, systematically reducing AMD concentration
• Sequences proceeds to align with quarterly estimated-tax due dates (April 15, June 16, September 15, January 15) to cover EFTPS and FTB payments without a separate liquidity event
• Includes a minimum-price condition if concentration is being managed over multiple years and the employee is comfortable accepting some timing risk
• Layers in charitable giving of appreciated shares for long-held lots eligible for the long-term holding period

See the 10b5-1 trading plans guide for the full SEC rule analysis and plan design considerations.

AMD ESPP

AMD operates an Employee Stock Purchase Plan (ESPP) qualified under IRC § 423. The ESPP allows eligible employees to purchase AMD shares at a discount through payroll deductions. Key mechanics (verify current terms in your AMD equity portal, as plan details can change):

• Purchase discount: Shares are purchased at a discount to market price. Plans qualifying under § 423 can offer up to a 15% discount.
• Tax treatment — qualifying disposition: If you hold ESPP shares for more than two years from the offering date and more than one year from the purchase date, the gain is split: the discount element is ordinary income; any appreciation above the discount is taxed at long-term capital gains rates. In California, this distinction matters for federal purposes only — California taxes all gains as ordinary income regardless.
• Tax treatment — disqualifying disposition: If you sell within these holding periods, the entire spread at purchase is ordinary income in the year of sale. Selling ESPP shares immediately after purchase is often the correct choice in California, where there is no preferential LTCG rate to protect. Holding to qualify only makes sense if you believe AMD will appreciate significantly and your federal LTCG rate is meaningfully lower than your federal ordinary rate.
• Form 3922 and cost basis: AMD (or its transfer agent) will send a Form 3922 after each ESPP purchase. The correct cost basis for your 1099-B is the purchase price — the price you actually paid — not the market price at purchase. Many custodians report ESPP cost basis incorrectly. See the ESPP tax guide for a full explanation of the Form 3922 basis trap.

State tax for AMD employees

AMD's major U.S. offices are in Santa Clara CA (headquarters), Austin TX, Bellevue WA, and Boxborough MA. The state tax treatment of RSU vest income differs significantly across these locations.

California (Santa Clara)

The majority of AMD's senior technical and leadership workforce is concentrated in the Santa Clara headquarters area. California rules that affect RSU holders most:⁵

• No preferential LTCG rate: California taxes all capital gains as ordinary income at up to 13.3%. Holding AMD shares for 12+ months after vest provides no California tax advantage.
• 13.3% top rate: Applies to taxable income above $1,000,000 for single filers. Senior and staff engineers at AMD whose salary plus RSU vesting reaches this threshold pay a combined federal + state rate of 50.3% on the marginal dollar of RSU income.
• Nonresident grant allocation: If you moved out of California while AMD grants awarded during your California employment remain unvested, California asserts a claim on the income based on the ratio of California workdays from grant date to vest date — the grant-to-vest apportionment formula per FTB Publication 1100. Moving to Texas or Washington does not eliminate California's claim on prior grants; it reduces it proportionally. For AMD engineers who relocated during or after the pandemic, this is a commonly missed exposure. See the RSU state tax guide.

Texas (Austin)

Texas has no state income tax. AMD employees at the Austin campus pay federal tax only on RSU vest income — roughly 37% at the top federal bracket — versus 50.3% in California. The effective annual difference on $150,000 of RSU vesting is approximately $20,000 in avoided state tax. However, employees who moved from California to Austin and still have unvested California-granted RSUs will owe California nonresident tax on those vests until the grants are fully vested. Texas also has no capital gains tax, making it favorable for holding and eventually selling appreciated AMD shares.

Washington (Bellevue)

Washington has no state income tax, so Bellevue-based AMD employees pay federal tax only on RSU vest income. However, Washington's capital gains excise tax — effective 2023 — imposes a 7% rate on annual long-term capital gains exceeding approximately $278,000 and a 9.9% rate above a higher threshold. AMD employees who relocated from California to Washington see a large reduction in RSU vest tax, but face the Washington capital gains tax when selling appreciated AMD shares held after establishing Washington domicile.

Massachusetts (Boxborough)

Massachusetts has a flat income tax rate of 5% (plus a 4% surtax on income over $1,000,000 effective 2023, creating a combined 9% top rate on high income).⁶ Massachusetts does provide a preferential capital gains rate of 8.5% for long-term gains, which is meaningfully lower than the ordinary income rate — unlike California. This means holding AMD shares for 12+ months after vest has some state tax value in Massachusetts, unlike in California.

Special situation: former Xilinx employees

AMD completed its acquisition of Xilinx in February 2022 for approximately $49 billion in stock. Xilinx shareholders received 1.7234 AMD shares for each XLNX share they held at closing. Former Xilinx employees who held XLNX RSUs or restricted stock through the merger received AMD RSUs in exchange, with adjusted share counts and a carryover vesting schedule.

Key tax considerations for former Xilinx employees now at AMD:

• Cost basis in converted RSUs: AMD RSUs received in exchange for XLNX RSUs in a § 368 reorganization carry over the tax attributes of the original XLNX awards. The tax event still occurs at vest, at the FMV of AMD shares on the vest date — no tax was triggered by the conversion itself.
• AMD shares received in the merger (from XLNX stock): Xilinx shareholders who received AMD shares in the merger have a cost basis equal to the FMV of AMD shares received (approximately $143–$160/share depending on the closing date). AMD's subsequent price movement creates capital gain or loss relative to that basis, not relative to any original Xilinx cost basis. If you rolled your XLNX stock into AMD shares in a qualifying reorganization, consult a tax professional to confirm your specific basis.
• Grant date reset: The holding period for LTCG purposes on AMD shares acquired in the merger began on the merger closing date (February 14, 2022), not the original Xilinx grant date. Shares held since then are likely already long-term.

Year-end planning moves for AMD employees

The fourth quarter is the highest-leverage window for tax planning. Key actions before December 31:

1. Maximize 401(k) contributions: The 2026 employee 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).⁷ Pre-tax contributions reduce AGI, shifting RSU vest income out of the top federal and California brackets.
2. Mega backdoor Roth: If AMD's 401(k) plan allows after-tax contributions and in-plan Roth conversions, the 2026 § 415(c) total annual additions limit is $72,000. After deferral and employer match, there may be $35,000–$47,000 of after-tax contribution space. Verify your AMD plan documents — not all plans support the mega backdoor feature. See the mega backdoor Roth guide.
3. Quarterly estimated tax check: After the Q3 vest (typically September), compare year-to-date withholding against your projected full-year tax liability. An EFTPS payment to the IRS and an FTB payment to the California Franchise Tax Board before January 15 can close a shortfall without underpayment penalty if you meet the prior-year safe harbor (110% of prior-year tax for AGI over $150K). See the estimated tax guide.
4. Tax-loss harvesting: Identify unrealized losses in your broader portfolio to offset AMD gains realized during the year. Be alert to the wash-sale rule: if you hold AMD in a taxable account, newly vested AMD shares acquired within 30 days of a loss sale in AMD create a wash-sale situation. See the wash-sale guide.
5. Donate appreciated AMD shares: If you hold AMD shares acquired at a lower vest-day FMV that have appreciated over the past 12+ months, donating them to a donor-advised fund before December 31 locks in a deduction at full FMV and eliminates capital gains recognition entirely. For California residents, the combined avoided capital gain rate is up to 13.3% state + 23.8% federal on the gain — a 37.1% savings on gains you never recognize. See the charitable giving guide.
6. Review or establish a 10b5-1 plan: If you want to execute AMD sales in 2027 open windows — or execute during blackout periods — you need to establish the plan during an open window in Q4 2026. The 90-day cooling-off period means a plan adopted in early November can begin executing in early February. Don't wait until the window is closing.
7. NQDC election deadline: If AMD offers a non-qualified deferred compensation plan for eligible employees, the election to defer 2027 compensation must typically be made by December 31, 2026. NQDC can materially reduce current-year W-2 income for very high earners. See the NQDC guide.
8. ISO exercise window (if applicable): Long-tenured AMD employees who received incentive stock options when the stock was at low prices may still hold in-the-money ISOs. Exercising before year-end starts the 12-month LTCG clock and the 2-year from grant date qualifying disposition clock, but may trigger AMT in the exercise year. Run the AMT calculation before exercising. See the ISO AMT calculator and the stock option exercise timing guide.

When AMD employees need an equity compensation specialist

Several AMD-specific scenarios benefit significantly from a specialist advisor:

• Cliff vest approaching: If you're nearing the first anniversary of an AMD new-hire grant — receiving 25% of the total award in one quarter — you need W-4 and estimated-tax planning before the vest date. A single cliff vest at senior AMD levels can generate $100,000–$300,000 of ordinary income in one quarter.
• AMD position exceeds 20% of net worth: Long-tenured AMD employees who held shares through the company's run from $5 to $150+ are holding significant single-ticker concentration. A specialist can model systematic sell plans, direct indexing replacement strategies, charitable options, and exchange funds to reduce exposure in a tax-efficient sequence.
• California relocation planning: If you're considering moving from Santa Clara to Austin or Bellevue, the interaction of California's nonresident allocation on unvested grants, the AMD capital gains embedded in shares you hold, and Washington's capital gains excise tax requires careful sequencing before the move. See the RSU state tax guide.
• ISO/AMT planning for long-tenured AMD employees: AMD employees who received option grants before the shift to RSU-heavy compensation may still hold ISOs or NSOs. Exercising ISOs with large spreads triggers Alternative Minimum Tax in complex ways that interact with RSU ordinary income. See the ISO AMT calculator.
• Former Xilinx employee basis questions: The tax mechanics of AMD-for-XLNX share conversions and subsequent AMD RSU vesting are complex. If you're unsure about your cost basis in AMD shares received in the merger, or how your Xilinx-era equity was converted, an advisor who understands § 368 reorganizations and RSU compensation can clarify before you file.
• Leaving AMD: Unvested RSUs typically forfeit at termination. If you're negotiating an exit package or a layoff, unvested equity may be a negotiating point. Vested AMD shares need documented cost basis before departure. See the layoff equity guide.
