What Does an RSU Tax Accountant Do?
An RSU-focused tax accountant helps employees properly report the compensation recognized when RSUs vest and reconcile that compensation with the subsequent sale of shares. The work can include reviewing W-2 equity income, brokerage Forms 1099-B, supplemental equity statements, cost basis, Form 8949 adjustments, estimated taxes, California taxes, ESPPs, stock options, and the timing of equity sales.
RSU Tax Preparation for San Jose & Silicon Valley
Restricted Stock Units can create several different tax reporting events during the same year. When RSUs vest, the value generally becomes compensation income. When the resulting shares are later sold, the sale is reported as a capital transaction. Your tax return therefore needs to connect the compensation reported at vest with the basis used when those shares are sold.
That reconciliation becomes particularly important when your brokerage statement does not reflect the basis you need to use for tax reporting. The IRS explains that Form 8949 is used to reconcile transactions reported on Form 1099-B with the amounts reported on your tax return, and that an incorrect basis may require an adjustment on Form 8949.
Moontree Tax works with San Jose-area technology professionals who have complex equity compensation and want their tax return prepared with the equity transactions understood as part of the larger tax picture—not treated as isolated brokerage transactions.
How RSUs Are Taxed: Vesting, Withholding & Selling Shares
A common source of confusion is treating an RSU vest and an RSU sale as one tax event. They are generally separate events that need to be reported correctly.
RSUs Vest
The value associated with vested shares is generally treated as compensation income. Your employer typically reports the applicable compensation on your W-2 and withholds taxes according to its payroll process.
Shares Are Withheld or Delivered
Your employer or brokerage may sell or withhold shares to satisfy tax obligations. The amount withheld should be reviewed against your overall federal and California tax position.
Shares Are Sold
A later sale creates a capital gain or loss based on the applicable adjusted basis and sale proceeds. The tax return must reconcile the brokerage reporting with the correct tax basis.
1099-B & RSU Cost Basis Reconciliation
One of the most important technical areas in equity compensation tax preparation is reconciling brokerage reporting with the tax basis that should be used on the return.
The IRS instructions for Form 8949 specifically address situations where the basis shown on Form 1099-B is incorrect. Depending on how the transaction was reported, taxpayers may need to enter the correct basis or make a corresponding adjustment using the applicable Form 8949 code.
Moontree Tax reviews the relevant brokerage and employer equity records rather than assuming the imported brokerage data is automatically the complete tax picture.
Example: How an RSU Sale Can Create a Basis Reconciliation
$100,000 of compensation value
$105,000 proceeds
$5,000 capital gain
The example is simplified and assumes no other basis adjustments, transaction costs, or special tax circumstances. Actual reporting depends on the taxpayer’s documents and transaction history.

Frequently Asked Questions About RSU Taxes
How are RSUs taxed when they vest?
RSUs generally create compensation income when the shares vest and become transferable under the applicable plan terms. The employer generally reports the relevant compensation through payroll, with the applicable withholding reflected in payroll records.
Why doesn’t my 1099-B match the basis I expected for my RSUs?
Brokerage reporting and tax-return basis can require reconciliation. The IRS Form 8949 instructions specifically provide procedures for correcting an incorrect basis reported on Form 1099-B. The appropriate treatment depends on whether the basis was reported to the IRS and the details of the transaction.
Do I pay tax twice when I sell RSU shares?
The compensation recognized at vest and the later capital gain or loss on a sale are separate tax calculations. If the correct basis is reflected on the return, the later capital gain generally represents the change in value after the applicable basis was established. A basis reconciliation is therefore important when brokerage reporting does not reflect the correct amount.
Should I sell my RSUs immediately when they vest?
There is no universal tax answer. Selling shortly after vest can limit the amount of additional price appreciation exposed to capital gains or losses, while holding shares creates continued exposure to the stock’s future price movement. The appropriate decision depends on your tax position, investment objectives, liquidity needs, and risk tolerance.
Why can I still owe tax if shares were withheld at vest?
Equity withholding is not necessarily the same as your final tax liability. Your ultimate federal and California liability depends on total income, deductions, credits, filing status, and other tax items. An RSU-focused tax plan can compare payroll withholding and estimated payments with the broader return.
Can an RSU tax accountant help with ESPP and stock options too?
Yes. RSUs, ESPPs, ISOs, and NSOs have different tax rules and reporting requirements. Moontree Tax coordinates these equity compensation types when they appear together on the same tax return.
