Tech Employer Equity & RSU Directory

Compare stock plan brokerages, vesting schedules (frontloaded 33/33/22/12, uniform 25% quarterly or semi-annual, and backloaded 5/15/40/40), and supplemental tax withholding election rules across major tech employers.

Stock Plan & Vesting Schedule Comparison

While every U.S. employer is subject to the same 22% federal supplemental withholding rate under IRC § 3402(g), the timing and size of your April tax shortfall depend on your company's vesting cadence and whether your brokerage portal lets you raise your withholding rate:

Vesting Cadence & Release Dates: 5% Year 1, 15% Year 2, 40% Year 3, 40% Year 4 (Semi-annual in Y1-2, quarterly/semi-annual in Y3-4) (Typically May 15 and November 15 (plus February 15 and August 15 for quarterly grants in Years 3–4).)

Brokerage & Withholding Elections: Morgan Stanley at Work (Shareworks) / Fidelity — Inside the Amazon Stock Portal (via Morgan Stanley at Work or Fidelity NetBenefits), navigate to Tax Withholding Elections prior to the open trading window preceding your May 15 or November 15 vest. If your plan permits supplemental rate overrides, increase federal withholding from 22% to 32% or 35%. Note that withholding rate changes cannot be modified once an insider trading blackout window closes or within 10 business days of a scheduled release.

Multi-Year Tax Risk Profile: The primary tax trap at Amazon is the Year 2 to Year 3 transition. In Years 1 and 2, your W-2 is largely base salary + monthly cash bonus, making payroll withholding relatively predictable. In Year 3, 40% of your initial grant vests in two or four concentrated spikes—plus any stock appreciation since your hire date. If AMZN appreciates 30% between Year 1 and Year 3, your taxable W-2 income surges far above prior-year levels. Relying on the 110% prior-year IRS Safe Harbor is critical during Year 3 so you are not penalized before April.

Vesting Cadence & Release Dates: Frontloaded 33% Year 1, 33% Year 2, 22% Year 3, 12% Year 4 (Monthly vesting; quarterly for certain international/legacy grants) (25th of each month (settling into Schwab/Morgan Stanley within 2–3 trading days). Annual refreshers stack each March/April.)

Brokerage & Withholding Elections: Charles Schwab / Morgan Stanley — Google allows U.S. employees to adjust their federal supplemental tax withholding rate directly inside Charles Schwab Equity Award Center (under Account Settings -> Tax Withholding Elections). Because GSUs vest monthly, updating your rate to 32%, 35%, or 37% early in Q1 applies to all remaining monthly vests for the calendar year—eliminating the need to mail manual quarterly Form 1040-ES checks.

Multi-Year Tax Risk Profile: Because Google grants frontloaded initial awards (33% in Years 1 and 2) and stacks annual equity refreshers every spring, Year 2 and Year 3 represent peak overlapping vest velocity (33% of initial grant + 25% of Refresher 1 + 25% of Refresher 2). Furthermore, because performance bonuses pay out in Q1, Googlers who hit the $184,500 Social Security cap by spring see their take-home pay rise mid-year while their true marginal income tax bracket climbs into the 35%–37% tier.

Meta Platforms

Vesting Cadence & Release Dates: Uniform 25% per year, vesting quarterly in February, May, August, and November (no 1-year cliff for standard new-hire grants) (February 15, May 15, August 15, and November 15 each calendar year.)

Brokerage & Withholding Elections: Charles Schwab Stock Plan Services — Meta is one of the most flexible tech employers for supplemental tax elections, permitting employees to elect any custom federal withholding percentage between 22% and 37%. You must submit your updated rate election prior to the quarterly cutoff date (typically around the 1st of the vest month—February 1, May 1, August 1, or November 1) for it to apply to that quarter’s release.

Multi-Year Tax Risk Profile: Meta’s annual refresher grants (awarded in March, first vesting in May) stack rapidly when performance ratings ("Exceeds" or "Redefines") apply multipliers. By Year 3 or Year 4, an E5 or E6 engineer often has four simultaneous grants vesting on the 15th of each quarter. If cumulative supplemental wages (March bonus + four quarterly vests) cross $1,000,000 in Q3 or Q4, Schwab automatically jumps federal withholding from 22% to 37% on the excess, while the first $1,000,000 remains underwithheld by up to $150,000.

Apple

AAPL Ref FMV: $235 • Publicly Traded
Open Apple Calculator →

Vesting Cadence & Release Dates: Semi-annual vesting (25% per year split into two 12.5% tranches every 6 months) (April 15 and October 15 (new-hire grants may vest on the 1st or 15th of the 6-month anniversary month; annual October refreshers vest April 15 & October 15).)

Brokerage & Withholding Elections: E*TRADE by Morgan Stanley — Log in to E*TRADE Stock Plan (or Apple’s internal people portal) at least 2–3 weeks before April 15 or October 15 to verify whether supplemental tax withholding rate elections are open for your grant type. In addition, Apple employees participating in the Employee Stock Purchase Plan (ESPP) with a 15% lookback discount should account for disqualifying disposition ordinary income on their W-2.

Multi-Year Tax Risk Profile: The semi-annual April 15 / October 15 schedule creates an acute IRS estimated tax timing mismatch. Specifically, IRS Q2 estimated taxes cover April 1–May 31 (due June 15), while Q3 covers June 1–August 31 (due September 15), and Q4 covers September 1–December 31 (due January 15). Because Apple’s vests occur in April (Q2 period) and October (Q4 period), employees have $0 vest income in Q1 and Q3 but huge spikes in Q2 and Q4.

Microsoft

MSFT Ref FMV: $420 • Publicly Traded
Open Microsoft Calculator →

Vesting Cadence & Release Dates: 25% annual vest on initial on-hire stock awards (quarterly after Year 1); 20% per year over 5 years (quarterly) on annual stock rewards (February 15, May 15, August 15, and November 15 (August 31 / September 15 for annual rewards cycle).)

Brokerage & Withholding Elections: Fidelity Investments (NetBenefits) — Inside Fidelity NetBenefits (or Microsoft’s payroll portal), employees can either adjust their federal W-4 Step 4(c) "Extra Withholding" per paycheck or, where enabled for specific stock plan tranches, adjust supplemental withholding percentages in Fidelity prior to the quarterly record date. Adjusting W-4 withholding is often preferred because payroll withholdings are treated by the IRS as paid evenly across all four quarters.

Multi-Year Tax Risk Profile: Because Microsoft’s annual stock awards vest over 5 years (5% per quarter across 20 quarters), years 4 and 5 produce the "five-grant stack" effect: you simultaneously vest tranches from five distinct grants every quarter. Combined with Microsoft’s September annual cash bonus (also withheld at the 22% supplemental rate), Q3 and Q4 cumulative supplemental income routinely pushes senior engineers from the 24%/32% bracket into the 35%/37% bracket.

Nvidia

NVDA Ref FMV: $135 • Publicly Traded
Open Nvidia Calculator →

Vesting Cadence & Release Dates: 4-year initial grant (25% Year 1 cliff, then 6.25% quarterly); annual focal grants vest 6.25% quarterly with no cliff (Typically the 3rd Wednesday of March, June, September, and December.)

Brokerage & Withholding Elections: E*TRADE by Morgan Stanley / Charles Schwab — Nvidia employees should review their supplemental withholding elections in E*TRADE / Schwab or via Nvidia Payroll prior to the March, June, September, and December vest dates. Even if your annual vests exceed $1,000,000 and trigger the mandatory 37% tier on the excess, the initial $1,000,000 tranche still creates an ~13%–15% federal gap (and a ~3.1% California gap above the 10.23% flat rate) unless you make quarterly estimated payments.

Multi-Year Tax Risk Profile: When a volatile high-growth stock like NVDA vests at an elevated FMV in March and June, you owe ordinary income tax locked in at that exact day’s share price—even if the stock subsequently pulls back 20%–30% later in the year. Failing to liquidate the incremental shares needed to cover your 15% tax shortfall on the vest date exposes you to the risk of owing taxes on peak share prices with depreciated shares.

Stripe

PRE-IPO Ref FMV: $42 • Late-Stage Private
Open Stripe Calculator →

Vesting Cadence & Release Dates: Quarterly vesting (historically double-trigger RSUs modified via company-sponsored liquidity and tender offer settlements) (Quarterly vest tranches paired with periodic company-sponsored tender offers and RSU tax-withholding liquidity settlements.)

Brokerage & Withholding Elections: Carta / Morgan Stanley at Work — Unlike public company employees who can log into Schwab or Fidelity any day and sell extra shares on the open market to pay the IRS in April, Stripe employees hold private shares that cannot be traded outside designated tender offer windows. Therefore, when a tender offer window opens on Carta / Morgan Stanley at Work, you must sell enough secondary shares (or set aside cash from your base salary) to cover the 13%–15% federal and state underwithholding gap.

Multi-Year Tax Risk Profile: The biggest danger with late-stage private RSUs is the "Illiquidity Tax Squeeze." If your RSUs vest and trigger W-2 ordinary income during a calendar year, the IRS demands cash payment by each quarterly estimated deadline (or April 15), regardless of whether you can sell the remaining private shares. Never rely on future tender offers happening before April 15 to fund prior-year tax shortfalls.

Vesting Cadence & Release Dates: Quarterly vesting following 1-year cliff, with company-sponsored RSU settlement and secondary tender liquidity events (Quarterly vest schedule paired with structured institutional liquidity rounds and tax-withholding net settlements.)

Brokerage & Withholding Elections: Carta / Morgan Stanley at Work (Shareworks) — Before participating in a Databricks liquidity event or RSU settlement election via Carta or Shareworks, check whether the election portal allows you to opt into maximum statutory withholding (up to 37% federal and top-bracket state rates) or calculate how many additional vested shares you must tender into the secondary offering to generate cash for your Form 1040-ES and California Form 540-ES vouchers.

Multi-Year Tax Risk Profile: When a private company waives the liquidity condition on multi-year accumulated service-vested RSUs all at once—or upon an eventual IPO lockup release—several years of equity grants can become taxable in a single calendar year. This multi-year bunching pushes almost the entire vest into the top 37% federal bracket and 13.3%+ California millionaire bracket, making accurate safe-harbor modeling essential.
