Restricted stock units (RSUs) are a great way to share in your company’s success, but the taxes can feel like a puzzle. This
RSU tax withholding guide
explains the key rules every employee needs to know in 2025, using simple, easy-to-read words. We’ll cover what RSUs are, how tax withholding works, and how tools like online calculators can help you plan without stress. Whether you’re a tech worker, a startup employee, or new to RSUs, understanding these rules will help you manage your taxes and avoid surprises.
What Are Restricted Stock Units (RSUs)?
RSUs are shares of your company’s stock given as part of your pay. You don’t own them right away; they vest over time, often based on how long you stay or if you meet specific goals. For example, if you’re granted 1,000 RSUs vesting over four years, you might get 250 shares each year.
In 2025, RSUs are popular in industries like tech, finance, and startups because they tie your earnings to the company’s stock price. If the stock price rises, your RSUs grow in value, which is awesome for building wealth. But when they vest, the IRS treats their value as regular income, and your employer withholds taxes. This RSU tax withholding guide will break down the key rules to help you stay on top of your taxes.
Why RSU Taxes Are Complicated
RSU taxes can be tricky because:
Withholding Mismatch: The standard federal withholding rate (22%) might not match your actual tax rate, which depends on your total income.
Multiple Taxes: You pay federal, Social Security, Medicare, and state taxes, each with different rules.
Stock Price Swings: The tax amount depends on the stock price when RSUs vest, which can change quickly.
Bracket Jumps: Multiple vestings, like quarterly or monthly schedules, can push you into a higher tax bracket.
For example, if you earn $140,000 and $40,000 in RSUs vest, your income jumps to $180,000, possibly moving you from the 22% to the 24% federal bracket. Knowing the rules helps you plan and avoid surprises.
Key Rule 1: How RSU Taxes Work in 2025
When RSUs vest, their market value is added to your income, like a bonus. For example, if 100 shares vest at $80 each, that’s $8,000 taxed as income. Your employer withholds taxes as “supplemental wages.” Here’s how it breaks down in 2025:
Federal Taxes: Withheld at 22% for amounts under $1 million (37% above). For $8,000, that’s $1,760.
Social Security: 6.2% on income up to $176,100 total for the year. For $8,000, that’s $496, unless you’ve hit the cap.
Medicare: 1.45% with no cap, plus 0.9% if your total income is over $200,000 (single) or $250,000 (married). For $8,000, that’s $116.
State Taxes: Vary by state—0% in Texas, up to 13.3% in California. In California, $8,000 might mean $720 withheld.
The 2025 federal tax brackets for singles are: 10% ($0-$11,925), 12% ($11,926-$48,475), 22% ($48,476-$103,350), 24% ($103,351-$197,300), 32% ($197,301-$250,525), 35% ($250,526-$626,350), and 37% (over $626,350). Married filers have roughly double these ranges. If your income lands in a higher bracket, the 22% withholding might not cover your full tax bill.
When you sell RSU shares, you pay capital gains tax on any profit—long-term (0%, 15%, or 20%) if held over a year, or your regular rate if sold sooner. This guide focuses on vesting taxes, where withholding happens.
Key Rule 2: How RSU Tax Withholding Works
When your RSUs vest, your employer calculates their value based on the stock’s market price that day. They withhold taxes by:
Selling Shares: Most employers sell some vested shares to cover taxes, leaving you with “net” shares or cash.
Using Cash: Some take money from your paycheck instead.
Applying Rates: Federal (22% or 37%), Social Security (6.2% up to $176,100), Medicare (1.45% plus 0.9% if applicable), and state taxes.
For example, if $10,000 in RSUs vest, your employer might withhold $2,200 (federal), $620 (Social Security, if under cap), $145 (Medicare), and $900 (state, e.g., 9% in California), totaling $3,865. You’d get $6,135 in shares or cash.
Key Rule 3: Why Withholding Might Not Be Enough
The standard 22% federal withholding is a flat rate, but your actual tax rate depends on your total income, including salary, RSUs, and other earnings. If your income puts you in a higher bracket (like 24% or 32%), the 22% withholding won’t cover your full federal tax bill, and you could owe more at tax time. For example, a $150,000 earner with $50,000 in RSUs ($200,000 total) might be in the 24% bracket, meaning the $11,000 federal withholding falls short by $1,000.
Additionally, if your income exceeds $200,000 (single) or $250,000 (married), the extra 0.9% Medicare tax applies. State taxes also vary, and high-tax states like California can add significant withholding.
Key Rule 4: The Social Security Cap
Social Security tax (6.2%) only applies to income up to $176,100 in 2025. If your total income (salary plus RSUs) is above this cap, you stop paying Social Security tax for the year. For example, if you earn $160,000 and $30,000 in RSUs vest, only $16,100 of the RSUs is subject to Social Security tax ($998), not the full amount.
Key Rule 5: State Taxes Vary Widely
State income taxes depend on where you live. Some states, like Texas and Florida, have no income tax, so you pay 0% on RSUs. Others, like California (up to 13.3%) or New York (up to 10.9%), take a big chunk. For example, $20,000 in RSUs in California could mean $1,800-$2,660 in state taxes, while Texas means $0. Knowing your state’s rules is crucial for accurate planning.
Key Rule 6: Stock Price Volatility Affects Taxes
The tax amount is based on the stock price when RSUs vest. If the price is $100 per share on vesting day, 100 shares equal $10,000 in taxable income. If the price drops to $80 after vesting, you still pay taxes on $10,000, which can feel like a loss. Planning for price swings is key, especially in 2025’s volatile markets.

The 2025 federal tax brackets for singles are: 10% ($0-$11,925), 12% ($11,926-$48,475), 22% ($48,476-$103,350), 24% ($103,351-$197,300), 32% ($197,301-$250,525), 35% ($250,526-$626,350), and 37% (over $626,350).

Key Rule 3: Why Withholding Might Not Be Enough
The standard 22% federal withholding is a flat rate, but your actual tax rate depends on your total income, including salary, RSUs, and other earnings. If your income puts you in a higher bracket (like 24% or 32%), the 22% withholding won’t cover your full federal tax bill, and you could owe more at tax time.

Additionally, if your income exceeds $200,000 (single) or $250,000 (married), the extra 0.9% Medicare tax applies. State taxes also vary, and high-tax states like California can add significant withholding.
Key Rule 4: The Social Security Cap
Social Security tax (6.2%) only applies to income up to $176,100 in 2025. If your total income (salary plus RSUs) is above this cap, you stop paying Social Security tax for the year. For example, if you earn $160,000 and $30,000 in RSUs vest, only $16,100 of the RSUs is subject to Social Security tax ($998), not the full amount.

Knowing your state’s rules is crucial for accurate planning.
Key Rule 6: Stock Price Volatility Affects Taxes
The tax amount is based on the stock price when RSUs vest. If the price is $100 per share on vesting day, 100 shares equal $10,000 in taxable income. If the price drops to $80 after vesting, you still pay taxes on $10,000, which can feel like a loss. Planning for price swings is key, especially in 2025’s volatile markets.

This RSU tax withholding guide is very well explained and makes the complex rules much easier to understand. The way you broke down federal, Social Security, Medicare, and state taxes with clear examples really helps employees see the bigger picture. I also like how you highlighted the impact of stock price swings and different vesting schedules, since those are often overlooked but can change tax outcomes a lot. When thinking about planning tools, it’s clear that calculators play a big role in simplifying these details. For example, just as an RSU tax calculator helps estimate withholding, an
online VAT calculator
is equally useful for businesses to quickly figure out tax amounts on transactions. Both make complicated tax rules more manageable and reduce the chance of mistakes.
