When your equity starts turning into real money, taxes can feel more stressful than exciting. A big RSU vest can bump your income far higher than you expected. A stock option exercise can trigger new taxes you have never dealt with before. It often feels like the moment you finally gain financial momentum, the IRS shows up at the exact same time.
One tool many tech professionals do not realize they have is charitable giving. Not in the usual “write a check in December” sense, but in the form of donating appreciated shares. When used thoughtfully, this approach can lower your tax bill, increase the impact of your giving, and give you more control over years where your equity income lands at the top of your tax return.
At KB Financial Advisors, we talk about this strategy often because it blends two things most clients care deeply about: smart planning and meaningful generosity. Below is a guide that explores how charitable giving to offset RSU fits you and your stock option strategy.
Why Charitable Giving Matters In High Equity Years
Once your RSUs vest or your stock options are exercised and you hold those shares, they can start building long-term capital gains. If you eventually sell them, you pay capital gains tax on that growth. When you donate shares directly instead of selling them, you avoid that gain entirely and still receive a charitable deduction from your income based on the fair market value of the shares.
This creates a double benefit. You support a cause you believe in, and you use shares with built-in gain to potentially reduce your taxable income in a year where you might really need it. Think of it as redirecting tax dollars toward something more meaningful.
How Charitable Giving Works With RSUs
RSUs create ordinary income when they vest. Once the shares settle and you continue holding them, any future increase in value becomes a capital gain. This is where charitable giving can help. If you donate those shares after holding them long enough to qualify for long-term treatment, you may be able to deduct the fair market value and avoid tax on the appreciation.
This makes RSU giving particularly helpful in years where multiple vests push your income higher than usual or limit how much you can withhold through payroll. Donating appreciated shares gives you another lever to pull when you need to control the final numbers at tax time.
A Simple Example To Show How This Works With RSUs
Imagine one tranche of RSUs vests at a value of $100,000. On the day they vest, that full amount is treated as ordinary income. Even if you hold the shares and do nothing, the IRS counts that value as part of your wages for the year. That part is unavoidable.
Now imagine you hold the shares for more than a year and the stock grows to $120,000. If you sold the shares, the extra $20,000 of growth would normally be taxed as a capital gain.
But if you donate the shares instead of selling them, something interesting happens. You avoid paying capital gains tax on that $20,000 increase, and you may still receive a charitable deduction for the full fair market value of the shares at the time of the donation, which in this example is $120,000.
You have already paid tax on the original $100,000 at vest, but by donating the appreciated shares instead of selling them, you remove the tax that would have applied to the growth and potentially get credit for the full appreciated amount. It is one of the few situations where the tax rules work in your favor when you plan ahead.
How Charitable Giving Works With Stock Options
Stock options behave differently, but the idea is similar once the shares are yours. With Nonqualified Stock Options (NSOs), you create ordinary income at exercise. With Incentive Stock Options (ISOs), you create a potential Alternative Minimum Tax (AMT) impact at exercise and then manage holding periods to qualify for favorable tax treatment. After the exercise, once the shares have settled in your account and you meet the required holding period, you can donate the appreciated shares for the same type of benefit you see with RSUs.
The timing works a little differently with stock options. When you exercise NSOs, the spread between the strike price and the market price is treated as ordinary income. With ISOs, the spread can show up in AMT in the year you exercise. That tax cost is the main reason most people exercise options only when they plan to sell. Selling right away gives them the cash to cover the tax, so they are not left with a bill and no liquidity.
Because of this, many people never build long-term capital gain on their option shares. They exercise and sell immediately, which means there is no appreciation to donate later. If charitable giving is something you want to incorporate into your equity plan, you need to think ahead and consider exercising earlier than you normally would. You still pay the tax at exercise, but holding the shares long enough to qualify for long-term treatment can create appreciated stock that you can donate in a future year. It takes planning and cash flow awareness, but it can open the door to gifts that reduce future capital gains and support causes you care about.
An Example Of How This Works With Stock Options
Let’s say you have non-qualified stock options (NSOs) with a strike price of $10. The company’s stock is now worth $30. If you exercise the options today, the $20 spread is treated as ordinary income.
Imagine you exercise 1,000 options:
- Strike price: $10
- Market price: $30
- Spread: $20
- Ordinary income created: $20,000
You owe tax on that $20,000 in the year of exercise, even if you do not sell the shares. This is why most people only exercise when they plan to sell immediately. Selling gives them the cash to cover the tax bill.
But if you were considering charitable giving, this is how it would look.
Suppose you decide to exercise today and hold the shares. You pay the tax on the $20,000 of income out of pocket. A year later, the stock price rises from $30 to $40. Now your shares are worth $40,000.
If you donated the shares at this point, two things would happen:
- First, you avoid paying capital gains tax on the $10,000 of appreciation that occurred after exercise.
- Second, you may receive a charitable deduction for the fair market value of the donated shares, which is $40,000 in this example.
You still had to pay the tax created at exercise, but by holding the shares long enough to build long-term gain, you created appreciated stock that can be donated in a future year to offset income or support your charitable goals.
Trade-offs To Be Aware Of
Charitable giving of appreciated stock can be a smart tool, but it works best in specific situations. It is not a strategy you want to use on autopilot. It is something to apply thoughtfully, especially when your tax year is already running high.
It can also be helpful when you are holding more company stock than you feel comfortable with. Many tech professionals accumulate shares simply because vests and exercises keep happening in the background. Donating appreciated stock gives you a way to reduce that concentration risk without realizing capital gains and without needing to use cash.
But it is important to understand the tradeoffs, especially with stock options. If you want to build long-term gain on option shares, you usually need to exercise early and hold the stock. That means paying tax upfront on the income created at exercise, even though you have not sold anything. If the stock rises after you exercise, the strategy can work well because you avoid capital gains and may receive a deduction for the full fair market value. But if the stock falls, you still owe the tax from the exercise year, and you have a less valuable asset in your hands. You cannot undo the tax even if the stock price cuts in half. This risk is the main reason most people wait to exercise until they plan to sell.
This means charitable giving of appreciated stock is best suited for people who have both the financial cushion and the risk tolerance to exercise before they sell, or for those whose RSUs have already grown significantly without any extra cost to them. It works less well for anyone who would struggle with the upfront tax or who feels uncomfortable holding shares that could fluctuate in value.
It can also be helpful when you want to give but prefer to protect your cash flow. Donating shares instead of writing a check allows you to support a cause without impacting your monthly budget, but the tradeoff is that you must be sure the shares are truly excess to your needs and that you are not relying too heavily on a single stock.
