Restricted Stock Units: Vesting, Payroll Income, Basis, and Later Sales
The RSU filing path has two events to reconcile: compensation when shares are delivered or treated as wages, and a later sale recorded by the broker.
Source framework: plan documents and current official guidance.
Start with the two RSU events: compensation and later sale
Restricted stock units usually represent a future right to receive shares or cash after stated conditions are satisfied. The practical tax question begins when the company delivers shares or cash and treats the value as compensation through payroll. That event and a later brokerage sale are not the same transaction. A strong RSU file keeps the award agreement, vesting or settlement statement, paystub, W-2, broker record, and later sale confirmation together so the same value is not misunderstood or counted twice.
At a compensation event, the employer may report value through payroll and withhold taxes by cash deduction, share withholding, or a sale-to-cover process. The number of shares that remain in the account does not itself explain the wage calculation. The grant and settlement documents, payroll register, and W-2 should be compared to establish what the employer treated as compensation. If shares are sold later, the sale proceeds and basis information require a separate lot-by-lot reconciliation.
Build one timeline from grant through sale: award date, vest or settlement, payroll date, W-2 reporting, shares withheld or sold, broker delivery, and later sale. Compare the documents before entering data into software. A qualified review is appropriate if W-2 wages and the sale record cannot be reconciled, basis appears missing, multiple lots were sold, the records cross states or years, or the amount is material. The objective is to support the return with contemporaneous records.
Read vesting, delivery, and payroll records together
At a compensation event, the employer may report value through payroll and withhold taxes by cash deduction, share withholding, or a sale-to-cover process. The number of shares that remain in the account does not itself explain the wage calculation. The grant and settlement documents, payroll register, and W-2 should be compared to establish what the employer treated as compensation. If shares are sold later, the sale proceeds and basis information require a separate lot-by-lot reconciliation.
Retain the grant notice, equity plan, vesting or settlement statement, value used by the employer, withholding notice, paystub, W-2, broker trade confirmation, Form 1099-B, supplemental broker statement, and Form 8949 workpaper. Put the vest or settlement date, shares delivered, shares withheld or sold, payroll amount, and later sale date in one row. This is more defensible than relying on a broker screen that may not include employer compensation data.
A Form 1099-B can report a later sale even when the compensation value was already included in wages. That is why a zero or incomplete broker basis figure deserves document review, not automatic acceptance. The return-preparation work is to reconcile the sale record with the employer wage record and the actual lot history under current Form 8949 and Schedule D instructions. Do not choose an adjustment code or final basis from a generic article without matching it to the statements for the transaction.

Same-day sales, sell-to-cover, a broker supplemental statement, a cross-year sale, corporate actions, departure, private-company delivery, multistate work, or multiple lots can make an RSU record more complex. A withholding amount can be insufficient or excessive relative to the full return, and a broker form can have noncovered or adjusted basis information. These are reconciliation issues, not proof of an IRS problem by themselves.

Restricted Stock Units (RSUs) Tax Treatment FAQs
For “Are RSUs taxed twice when they vest and when I sell?,” the answer depends on the separate compensation and later-sale events, W-2 reporting, actual basis, and the lot documents.
