We reconcile brokerage Form 1099-B data to correct adjusted cost basis figures and model exercise scenarios to mitigate Alternative Minimum Tax (AMT) exposure.

Do you handle California Pass-Through Entity (PTE / AB 150) Tax elections?

Fixing Charles Schwab 1099-B Basis Errors for Alphabet Employees

Alphabet distributes Google Stock Units (GSUs)—Google’s version of Restricted Stock Units—through Charles Schwab. When your GSUs vest on the 25th of the month, the fair market value of those shares is immediately added to your W-2 wages. However, when you liquidate shares through Schwab, IRS custodian regulations require Schwab to report the cost basis as $0 or leave it unadjusted on Form 1099-B.

If you import your Schwab tax forms directly into DIY tax software without manual adjustments, the IRS taxes your equity income a second time as a phantom capital gain. At Moontree Tax Service, we specialize in Alphabet tech compensation. We pull your Schwab Supplemental Information statements and apply Form 8949 (Code B/O) adjustments directly through our RSU & GSU cost basis hub, protecting Googlers in Mountain View, Sunnyvale, and Palo Alto.

The Google Monthly Vest Withholding Shortfall

Monthly Vesting Schedule: Google GSUs vest on the 25th of every month. For an L6 SWE, a monthly vest might equal $20,000 in GSUs.
Automatic Sell-to-Cover: Google automatically withholds shares at the standard federal supplemental rate of 22%.
The Tax Bracket Shortfall: High-earning tech households with combined incomes over $450k face marginal federal tax rates of 32%, 35%, or 37%.
The Cumulative Gap: A 10% to 15% withholding shortfall across 12 monthly vests creates a $24,000 to $36,000 tax bill at year-end—along with IRS Form 2210 underpayment penalties if not managed proactively.

Navigating Alphabet-Specific Equity Mechanics

Google’s equity structure has distinct features that require tailored tax execution:

1. Monthly GSU Vest Schedules

Unlike annual or quarterly vest tech companies, Google’s monthly vesting schedule creates 12 distinct cost-basis tranches per year. We reconcile all 12 vest events against your Schwab supplemental trade confirms.

2. Mega Backdoor Roth & 401(k) Maximization

Google offers one of the best 401(k) plans in Silicon Valley, including 50% employer matching and after-tax in-plan Roth conversions (Mega Backdoor Roth). We integrate your GSU cash flow to maximize these contributions.

Frequently Asked Questions for Google Employees

Why does Charles Schwab report $0 basis on my Google 1099-B?

Federal law prevents stock custodians from automatically adjusting cost basis for non-statutory equity awards on 1099-B forms. Schwab reports gross proceeds and leaves basis unadjusted. We extract your Schwab Supplemental Statements to report the exact fair market value at vest on IRS Form 8949.

Should I sell my Google GSUs as soon as they vest on the 25th?

Selling GSUs immediately upon vest triggers almost zero capital gains tax because the sale price closely matches the vest-date fair market value already taxed on your W-2. Holding shares increases single-stock concentration risk in your broader portfolio.

How does Google’s 401(k) Mega Backdoor Roth impact my overall tax picture?

Google allows up to $70,000+ in total annual 401(k) contributions through employee pre-tax, employer match, and voluntary after-tax contributions. Converting after-tax contributions immediately to Roth inside the plan creates tax-free future growth that complements your taxable GSU liquidations.
