How Are RSUs Taxed? What to Know Before Your Restricted Stock Units Vest
Updated: Sep 16
Receiving restricted stock units as part of your compensation can feel straightforward: your employer grants you company equity, and shares become available over time. The tax consequences, however, may not become clear until a vesting date appears on your calendar—or until you receive a tax bill that is larger than expected.
Are RSUs taxable when they are granted? What happens when RSUs vest? Why are taxes withheld when shares vest? What happens if you keep the shares and sell them later?
A useful way to understand how RSUs are taxed is to separate the process into four stages:
Grant → Vest/Settlement → Hold → Sell
Each stage can have different tax implications. In a typical arrangement, the grant is generally not the primary taxable event. Compensation income generally arises when the RSUs vest and are settled, and a later sale of the shares may create a separate capital gain or loss.
What Are Restricted Stock Units (RSUs)?
An RSU is generally an employer's promise to provide company stock—or, depending on the plan, an equivalent cash value—after specified vesting requirements are satisfied. Those requirements may involve continued employment, performance conditions, or other terms in the award agreement.
An RSU grant is not the same as immediately owning unrestricted shares. Before vesting, you generally do not have the same ownership rights as someone who already holds delivered company stock. The details depend on the employer's plan and settlement terms, so the award agreement is an important source document.
The basic tax question is not simply whether you received an RSU grant. It is when the award becomes taxable under the terms of the arrangement and what happens after shares are delivered. For a broader look at where RSUs fit alongside stock options and ESPPs, see Equity Compensation and Taxes: What High-Income Earners Should Know.
Are RSUs Taxed When They Are Granted?
In a typical RSU arrangement, receiving the grant generally does not itself create current taxable income. The employee has received a promise of future stock or value, but not yet unrestricted shares or cash.
The later vesting and settlement process matters because compensation income generally arises when the employee receives the shares or cash under the terms of the award. In many conventional RSU arrangements, vesting and settlement occur at or near the same time, but the exact timing depends on the plan. This distinction between the grant date and the vesting/settlement date is central to understanding RSU taxes.
The precise result can depend on the plan, whether the award is stock-settled or cash-settled, and the facts of the transaction. For a broader discussion of equity compensation and tax planning, readers can review tax planning for high-income earners. That resource discusses equity compensation alongside other issues that may affect a higher-income taxpayer's overall tax picture.
What Happens When RSUs Vest?
When RSUs vest and are settled, the value delivered to the employee is generally treated as compensation income. In a conventional stock-settled arrangement, this usually means the fair market value of the shares delivered at the relevant settlement event is included in taxable wages, subject to the plan terms and applicable tax rules.
RSU compensation is generally processed through payroll and reported with other wage income on Form W-2. The employer also generally has withholding obligations when the compensation is recognized.
This is the first major taxable event in the typical RSU lifecycle. It is separate from any gain or loss that occurs after you receive the shares.
A Simple RSU Vesting Example
Assume an employee has 500 RSUs vest and settle when the company's stock is worth $100 per share.
500 shares × $100 per share = $50,000 of value
In a simplified, stock-settled example, approximately $50,000 may be treated as compensation income when the shares are delivered, subject to the actual plan and the employee's circumstances. The employer may withhold some shares or sell some shares to help satisfy required withholding, so the employee may receive fewer than 500 shares in the brokerage account.
Suppose the employee receives the remaining shares and later sells them for $120 per share. The initial $100-per-share value was associated with the compensation event. The increase from $100 to $120 is a separate change in value after the shares were acquired and may result in a capital gain when the shares are sold.
This example is simplified and educational. It does not calculate an individual's final tax liability or account for every possible plan or transaction detail.
How Are Taxes Withheld From RSUs?
Employers generally must withhold taxes when taxable RSU compensation is recognized. The method used depends on the employer's plan, payroll procedures, and applicable requirements. Common approaches may include:
Withholding a portion of the shares that vested
Selling enough shares to cover required withholding
Processing withholding through payroll or another method permitted by the plan
For example, an employee might see 500 RSUs vest but receive fewer than 500 shares in the brokerage account because some shares were withheld or sold to cover required taxes and other amounts. The exact number depends on the withholding calculation and the plan's procedures.
The number of shares withheld does not, by itself, determine the employee's final tax liability. It represents an amount paid toward taxes through withholding. The employee's complete tax return will take into account total income, deductions, credits, filing status, and other relevant facts.
Why RSU Withholding May Not Equal Your Final Tax Liability
“My employer withheld taxes when my RSUs vested. Why could I still owe money?”
Employer withholding is a prepayment, not a final calculation of the tax shown on your return. It is possible for withholding to cover the eventual liability, exceed it, or fall short of it, depending on the taxpayer's overall circumstances.
Your annual tax picture may include more than one source of income, such as:
Salary and bonuses
Multiple RSU vesting events
Stock options or other equity compensation
Interest, dividends, or other investment income
Capital gains from selling investments or company stock
Income from a business, partnership, rental property, or other source
A substantial vesting event can increase taxable compensation for the year. Several vesting events may also occur during the same year, potentially changing the amount of tax that should be paid through withholding or estimated payments.
Estimated-tax rules and safe-harbor provisions may be relevant, but they depend on the taxpayer's prior-year tax, current-year income, withholding, and other facts. These issues deserve a calculation rather than an assumption that the withholding shown on a vesting statement is sufficient. For a deeper discussion of this issue, see Why Equity Compensation Can Leave You With an Unexpected Tax Bill.
What Happens If You Hold the Shares After Your RSUs Vest?
After the RSUs vest and shares are delivered, you generally own company stock. From that point forward, the value of those shares can rise or fall.
That later change in value is distinct from the compensation income recognized at vesting. If the shares increase in value after delivery, the increase may contribute to a capital gain when you sell. If the shares decline, the decrease may contribute to a capital loss, assuming the sale and basis are properly reported.
Whether to retain or sell company stock is an investment decision. Florence Tax LLC can explain potential tax consequences, but does not recommend whether an employee should hold or sell shares.
What Happens When You Sell Vested RSU Shares?
Selling shares acquired through an RSU award can create a second taxable event. The general calculation compares the sales proceeds with the shares' adjusted tax basis:
Sales proceeds − adjusted basis = capital gain or loss
The holding period also matters. Depending on how long the shares were held after acquisition, the resulting gain or loss may be classified as short-term or long-term under applicable tax rules. The tax treatment of a sale can also depend on transaction details and the taxpayer's overall circumstances.
Returning to the simplified example, suppose the shares had a value of $100 each when they were delivered and were later sold for $120 each. The $20-per-share increase may represent a capital gain. The $50,000 recognized as compensation at vesting is not simply taxed again as compensation when the shares are sold; instead, the later sale generally concerns the change in value after acquisition, assuming the basis is correctly established.

Why Cost Basis Matters With RSU Shares
Cost basis is generally the amount used to measure gain or loss when property is sold. With RSU shares, basis can be confusing because compensation income was already recognized when the shares vested.
In a typical stock-settled RSU arrangement, the value included in compensation when the shares are delivered generally becomes part of the tax basis of those shares. If that amount is not properly reflected, a later sale could appear to produce an inaccurate gain or loss. This is one reason it is important not to rely automatically on a single tax form without comparing the available records.
Relevant documents may include:
Form W-2 showing wage income
Form 1099-B reporting the stock sale
Brokerage statements
Vesting confirmations
Trade confirmations and transaction details
Brokerage reporting and tax-document presentation can vary. A Form 1099-B may not always present basis in the way a taxpayer expects, or additional adjustments may be needed when preparing the return. The IRS provides guidance on basis and sales reporting in materials such as Publication 550, Investment Income and Expenses and the Instructions for Form 8949.
Comparing the vesting value, payroll records, brokerage information, and sale records can help identify discrepancies before the return is filed.
What Records Should You Keep for RSUs?
Consider retaining the following records, where applicable:
RSU grant or award agreement
Vesting schedule
Vesting confirmations
Statements showing the fair market value when shares were delivered
Payroll records
Form W-2
Brokerage statements
Form 1099-B
Sale confirmations
Cost-basis information
These documents may be especially important when shares are sold in a later tax year. A vesting event and a sale may appear on different tax returns, so records from the original vesting year can help explain how the basis was determined.
When Should You Discuss an Upcoming RSU Vest With a Tax Professional?
A tax-planning conversation may be useful before a significant vesting event, particularly when:
A substantial number of RSUs will vest
Several vesting events are scheduled during the same year
RSU income will materially increase annual compensation
You also receive bonuses or other equity compensation
You are concerned about withholding
You have already experienced an unexpectedly large tax balance
A major vesting event will occur near year-end
You expect to sell a significant amount of company stock
The purpose of the conversation is not to assume that one tax strategy fits every RSU holder. It is to understand how the upcoming vesting event may affect your broader tax picture. It is to understand the potential tax consequences while there may still be time to review withholding, estimated payments, cash flow, recordkeeping, and the effect of multiple tax years.
This is consistent with Florence Tax LLC's proactive tax-planning approach. Reviewing an important financial decision before it occurs can provide more useful planning context than discovering the consequences during tax-return preparation. The firm's article on why tax planning should be a year-round conversation explains why these discussions do not need to wait until tax season.
Understanding Your RSUs Before They Vest
The RSU tax lifecycle is easier to follow when the events remain separate:
Grant → Vest/Settlement → Hold → Sell
The main points are:
The RSU grant itself generally is not the primary taxable event in a conventional arrangement.
Vesting and settlement can create compensation income.
Employer withholding is a payment toward tax liability, not the final tax calculation.
Holding the resulting shares introduces potential investment gains or losses.
Selling the shares can create a separate capital gain or loss.
Accurate cost-basis records matter when shares are sold.
If a substantial vesting event is approaching, reviewing the potential tax consequences beforehand may help you understand the year's overall tax picture and identify questions while there is still time to address them.
Have a Significant RSU Vesting Event Coming Up?
Substantial RSU vesting can affect taxable income, withholding, cash flow, and year-end tax planning. Florence Tax LLC helps individuals and high-income employees understand the tax consequences associated with equity compensation and evaluate relevant tax-planning considerations before and during the year.
To discuss your circumstances, request a consultation. The conversation can focus on tax treatment and reporting considerations without making an investment recommendation about whether you should hold or sell company stock.
