Restricted stock units can look straightforward in an offer letter, but the practical process spans several separate events. Your employer grants an award, the award vests under its plan terms, shares or their cash value are delivered, and payroll withholding is handled before you decide whether to sell or hold.

In short, how do rsus work? The grant is a promise of future stock, not stock you own immediately. When units vest, the vested amount generally becomes compensation reported through payroll, while the shares you receive create records you will need to track through a later sale. Your award agreement controls the schedule, cliffs, installments, and forfeiture terms.
For California employees, keeping the lifecycle clear helps separate employer withholding from your eventual tax position and helps prevent missing records when shares are sold. Start with the grant documents and follow each decision point from the original award through vesting and delivery.
How Do RSUs Work From Grant to Vesting?
RSUs are a form of equity-based compensation. The IRS describes equity compensation as pay based on the value of specified stock and lists restricted stock units among its examples. The practical process begins with an award, then moves through vesting before shares are delivered under the employer’s plan.
- Review the grant. The company issues an award that identifies the number of units, the relevant stock, and the conditions attached to the award. The California Franchise Tax Board’s Publication 1004 uses grant date to mean the date the company grants the award or option. Your award agreement, rather than a general description of RSUs, controls the specific terms. Check the grant date, number of units, vesting conditions, expiration or cancellation provisions, and treatment if your employment changes.
- Identify the vesting schedule. Vesting is the process by which you satisfy the conditions for the award. A schedule may use a cliff, periodic installments, or another arrangement. There is no universal RSU schedule, so record each vesting date shown in the agreement and confirm whether continued employment or other conditions apply. The FTB discusses vesting date terminology in its equity-compensation materials, but the precise event depends on the award type and plan language.
- Reach each vesting date. When the applicable conditions are met, the corresponding portion of the award vests. Keep the vesting confirmation, transaction record, and the number of shares or units involved. If a date changes, or a portion is withheld or canceled under the plan, retain the employer’s explanation with your records.
- Receive the shares or their equivalent. After vesting, the plan administrator delivers shares, or handles the award according to the agreement. Delivery may involve withholding or retaining some shares under the employer’s process. Review the account statement and payroll records so the units granted, units vested, shares delivered, and any shares withheld can be reconciled.
At this stage, focus on creating a complete timeline. Tax reporting and withholding are separate parts of the lifecycle and depend on the applicable facts and employer process.
What Happens on the Vesting Date?
The vesting date is the point when the portion of the award scheduled for that date is reviewed under the employer’s plan terms. Start by checking the equity platform or award statement for a confirmation that the tranche vested. The record should show the number of units released, the vesting date, and any shares withheld or sold to cover payroll obligations.
What happens next depends on the plan’s settlement process. Some employers deliver shares to the employee’s brokerage account shortly after vesting. Others automatically retain or sell a portion of the shares to address withholding, with the remaining shares delivered to the account. The award agreement and plan administrator’s instructions control the timing and mechanics. Do not assume that every employer uses the same settlement method.
How do RSUs work from grant through vesting and delivery of shares?
At vesting, the units generally move from an unearned promise under the award to a settled compensation event, subject to the specific plan terms. Review the confirmation against the original award agreement, especially if the schedule includes multiple installments, a cliff, performance conditions, or special rules for a leave of absence. A discrepancy is best raised with the plan administrator while the transaction details are readily available.
For an employee, the compensation connected with an equity plan may be reported through Form W-2. The IRS advises confirming that compensation from applicable plans is reported to the recipient and that appropriate employment taxes are withheld and paid. See the IRS discussion of equity-based compensation for the reporting context: IRS equity compensation information.
Keep the vesting confirmation, settlement statement, and payroll records together. Those documents help reconcile the shares received with the amount reported through payroll and provide a clear starting point for tracking the shares after delivery. Detailed tax treatment at vesting and sale is a separate analysis from the mechanics of the vesting event.
How Does Payroll Withholding Fit Into RSU Vesting?
When RSUs vest, the value treated as compensation generally moves through payroll. The employer must address the applicable employment taxes on equity-plan compensation. And the IRS says RSU income can be treated as wages for federal income-tax withholding in the specific circumstances described in its Chief Counsel memorandum. The exact amount withheld depends on the employer’s payroll process and the applicable plan and tax rules.
Withholding is a payment toward your tax obligation, not a final calculation of what you owe for the year. Your final liability can depend on your total income, filing status, deductions, credits, other investment activity, and state-specific rules. For California employees, it helps to evaluate vesting income alongside your other wages. See the explanation of California tax on W-2 wages for related state-income-tax context.
How shares or cash may cover withholding
Your award agreement or employer platform will usually specify how withholding is handled. One common process is sell-to-cover: the plan administrator sells enough newly delivered shares to help fund the required withholding and sends the proceeds to the employer or tax authority. You receive the remaining shares, subject to the plan’s terms and the actual value used for the transaction.
Some plans instead use cash withholding, which may require funds from your paycheck or another approved source. Other plans can use a combination of methods. Do not assume that every employer permits sell-to-cover, that the number of shares sold will be identical across plans, or that withholding fully covers your eventual tax bill. Review the award documents and the vesting statement to confirm the shares delivered, shares withheld or sold, and amounts reported through payroll.
A practical vesting workflow is to save the vesting confirmation, payroll record, and year-end Form W-2 together. Compare the compensation reported with your records, then account for the shares you retained and their later sale separately. This keeps the payroll event distinct from the investment decision that follows.
What Is the Tax Basis of Vested RSU Shares?
Tax basis is the amount of your investment in property for tax purposes. For vested RSU shares, it is the record you use to connect the share delivery event with a later sale. The basis is not simply a number to rely on from memory. It should be supported by the employer’s transaction records, payroll information, and brokerage statements.
Start a record for each vesting event. Save the vesting date, the number of shares delivered, the number withheld or sold to cover obligations. The number deposited into your brokerage account, and the per-share value shown in the employer or brokerage record. Also retain the relevant pay statement and Form W-2. The IRS says taxpayers must keep accurate records of items affecting basis so they can make the required computations. See IRS Publication 551 for the recordkeeping rule.
How basis connects to a later sale
When you sell vested shares, the basis becomes an input in determining the gain or loss on that disposition. The basic workflow is to identify the specific shares sold, confirm the sale proceeds and transaction costs, and compare those amounts with the basis recorded for the shares. The holding period and tax treatment can require additional analysis, but that calculation should begin with complete, lot-level records.
Do not assume that a brokerage statement alone tells the full story, especially when shares moved between accounts or when a later statement reports incomplete basis information. Reconcile the vesting confirmation, payroll record, and brokerage lot details while the transaction is recent. For the distinction between the vesting event and the later sale, see our RSU tax treatment at vesting and sale. If the shares are sold while you are a California taxpayer, the related state considerations may also matter; our page on California capital gains tax provides additional context.
Good records make the later filing process easier and help prevent a mismatch between reported proceeds and the basis you are entitled to use.
What Happens to RSUs When You Leave a Job?
When employment ends, the result depends on the terms of the equity plan and your individual award agreement. There is no universal rule that applies to every employer, job change, resignation, or termination. Review the agreement before assuming that shares will be forfeited, accelerated, or delivered.
Vested RSUs
RSUs that vested before your final employment date generally need to be handled according to the plan’s settlement and administrative procedures. Depending on the plan, the shares may already have been delivered to your brokerage account, or the employer may still need to complete settlement. Check your equity portal, pay statements, and brokerage records to confirm the following.
- Which awards vested before your employment ended
- Whether shares were delivered, withheld, or sold to cover applicable obligations
- The number of shares you actually received
- The date and value recorded for the settlement
Keep these records with your tax documents. They can help reconcile your Form W-2, brokerage reporting, and later transactions.
Unvested RSUs
Unvested awards are usually the most plan-specific part of the analysis. The award agreement may address forfeiture at termination, treatment after retirement, continued vesting under a severance arrangement, or special treatment following a merger or other corporate event. Those provisions can differ based on whether you resign, are terminated, retire, or meet a defined change-in-control condition.
Before leaving, ask the employer or plan administrator for the applicable agreement, your vesting history, and the deadline for any required election or action. Compare the documents with your final pay and equity statements. If the outcome affects a major compensation decision, have the agreement reviewed before relying on an assumption about your shares.
How Are RSUs Different From Stock Options?
RSUs and stock options are both forms of equity compensation, but they create different employee workflows. An RSU is generally a promise to deliver shares, or their value, after the award satisfies its vesting conditions. A stock option gives the holder the right to buy shares at a stated exercise price, subject to the plan and award agreement. The California Franchise Tax Board discusses these as distinct types of equity compensation, so the name of the award matters when you review your records and deadlines.
| Process point | RSUs | Stock options |
|---|---|---|
| Grant | The company grants units tied to a specified number of shares or value. | The company grants a right to purchase shares under stated terms, including an exercise price. |
| Vesting | Shares or share value generally become deliverable when the award’s vesting conditions are met. | The option becomes exercisable as it vests, but vesting alone does not purchase shares. |
| Exercise | There is typically no employee purchase step for the vested units. Review how the plan handles share delivery and withholding. | The employee must decide whether and when to exercise, follow the plan’s payment process, and confirm the shares are issued. |
| Process risks | Track vesting dates, delivery records, withholding, and the shares retained after any plan transaction. | Track vesting, expiration, exercise windows, payment requirements, and the possibility that exercising may not fit the employee’s objectives. |
For either award, start with the grant notice and governing plan documents. Confirm the number of units or options, vesting conditions, exercise window, and what happens if employment ends. Do not assume that one company’s schedule or process applies to another company’s award.
The practical distinction is that RSUs move from vesting toward share delivery, while options add an employee decision and transaction between vesting and ownership. Employees evaluating both awards can review California equity compensation planning for broader planning context.
What Should California Employees Track After Vesting?
Vesting is not the end of the recordkeeping process. Each vesting event creates information you may need when reviewing payroll, planning future sales, preparing your return, or changing jobs. Keep a separate record for every tranche rather than relying only on a brokerage summary at year-end.
- Vesting details: Save the award agreement, vesting date, number of shares released, and any plan-specific terms that affected delivery or forfeiture.
- Payroll records: Keep the pay statement showing the vesting event, shares withheld or sold for taxes, and compensation included in payroll. Confirm that the related compensation appears correctly on your Form W-2. The IRS notes that equity-plan compensation may be reported on Form W-2 and that appropriate employment taxes should be withheld and paid: IRS equity compensation resources.
- Share and basis records: Record the shares delivered, shares retained, acquisition information, and brokerage basis. IRS Publication 551 says basis is used to calculate gain or loss on a later sale and that taxpayers should keep accurate records of items affecting basis: Publication 551.
- Sale activity: Keep trade confirmations and note whether you sold immediately, held the shares, or sold in multiple transactions. Match each sale to the correct vesting lot before tax preparation.
Also note where you lived and worked during each relevant period. California’s treatment can depend on residency changes and the facts surrounding the compensation. The Franchise Tax Board’s Publication 1004 discusses equity compensation when residency status changes, but it does not replace a review of your award terms and work history. If you moved states, worked across state lines, or expect another large vesting event. Address the issue before filing rather than assuming one state’s rules apply to every tranche.

Frequently Asked Questions
How do RSUs work from grant through vesting and delivery of shares?
Your employer grants an award under a plan and award agreement that sets the vesting schedule, including any cliff, installments, or performance conditions. When a portion vests, the company generally delivers shares or their cash equivalent according to the plan. The grant itself is not the same as receiving unrestricted shares, so keep the agreement and vesting notices with your records.
What happens to RSUs when you quit your job?
The award agreement controls what happens when employment ends. Unvested units may be forfeited, while vested units may remain subject to a specific delivery or settlement process. Do not rely on a general rule. Review the agreement, the termination provisions, and your final equity statement before assuming that an award will continue or disappear.
Should I sell my RSUs immediately after they vest?
There is no universal answer. Consider your concentration in the employer’s stock, cash needs, investment allocation, trading restrictions, and tax records before deciding. Selling immediately can reduce single-stock exposure, while holding preserves market exposure and risk. Separate the investment decision from the payroll withholding decision, and review the detailed RSU tax treatment at vesting and sale before acting.
What should I keep for my RSU tax basis?
Keep the vesting confirmation, number of shares delivered, value reported as compensation, shares withheld for taxes, brokerage transaction history, and sale confirmation. The IRS defines basis as the amount of an investment in property for tax purposes and uses it to calculate gain or loss on a later sale. Accurate records help reconcile your Form W-2 with your brokerage reporting.
