Restricted Stock Unit (RSU)

Q: Are RSUs better than stock options?

RSUs have value as long as the stock is worth anything; options are worthless if the stock price is below the exercise price. RSUs deliver more predictable value and are simpler — no exercise decision or exercise cash outflow. Options can produce larger gains if the stock appreciates significantly because of leverage (the spread between exercise price and market price). RSUs are generally preferred by employees at established companies; options at early-stage startups where large appreciation is the goal.

Q: When are RSUs taxed?

RSUs are taxed as ordinary income at the time of vesting — the date shares are delivered. The FMV on the vesting date is compensation income, included on your W-2, and subject to income and payroll taxes. There is no tax at grant. If you sell immediately after vesting, there is typically minimal capital gain (only price movement between vesting date and sale date).

Q: Can RSU income affect business loan applications?

Yes. RSU income shown on W-2s is often treated as variable income by underwriters (it depends on continued employment and company stock price). For personal loan or mortgage applications, lenders may average 2 years of RSU income shown on tax returns and may require evidence the grant is ongoing. Business lenders evaluating owner income may include or exclude RSU income depending on its stability and likelihood to recur.

Also known as: RSU, restricted stock units, vesting RSU

Definition

A Restricted Stock Unit (RSU) is an employer's promise to deliver company shares (or cash equivalent) to an employee on a future vesting date. RSUs are taxed as ordinary income at vesting under IRC Section 83 — the employee receives taxable compensation equal to the fair market value of shares on the vesting date.

Detailed explanation

RSUs are the dominant equity compensation form at public companies and late-stage private companies. Unlike stock options, RSUs have intrinsic value as long as the stock price is positive — they don't require the employee to 'buy in' at an exercise price.

## Tax Treatment (IRC Section 83) Under [IRC Section 83](https://www.irs.gov/pub/irs-drop/rr-2012-29.pdf), RSUs are not taxed at grant — there is nothing of value until vesting because the employee has no current ownership. At vesting, the FMV of shares on the vesting date is included in the employee's W-2 as ordinary income, subject to federal income tax, state income tax, Social Security (up to annual wage base), and Medicare taxes. The employer typically withholds tax by delivering fewer shares (withhold-to-cover method) or deducting from payroll.

## Cost Basis The tax paid at vesting establishes the employee's cost basis. If shares are held post-vesting and later sold, the gain or loss is capital in character (short-term if held < 1 year; long-term if held ≥ 1 year). Most employees sell immediately at vesting to cover taxes and diversify, resulting in minimal capital gain.

## RSUs as Business Income (Self-Employed / Owners) Business owners issuing RSUs to employees must understand [IRC Section 83](https://www.irs.gov/businesses/small-businesses-self-employed/equity-based-compensation) compliance. The employer deducts the compensation expense when the employee recognizes income — creating an alignment between deductibility and taxability timing.

◈ Worked example

4-year vesting RSU grant: employee receives 2,000 RSUs with 4-year annual cliff vesting. Year 1 vest: 500 shares at $40 FMV = $20,000 taxable income on W-2.
Tax withhold-to-cover: 500 RSUs vest at $40/share = $20,000 gross income. 37% federal + 5% state marginal rate = 42% total → employer withholds ~210 shares ($8,400) and delivers ~290 shares net.
RSU cost basis: shares delivered post-withholding have a basis equal to the FMV on the vesting date. Shares held 13 months and sold at $55 → $15/share long-term capital gain taxed at 15-20% LTCG rate.
