If you work in tech or at a fast-growing company, chances are you’ve come across RSUs—Restricted Stock Units. They can be a valuable part of your compensation, but they also come with strings attached, especially when it comes to taxes and financial planning. Let’s break it all down so you can make the most of this benefit.
What Are RSUs and Why Do They Matter?
RSUs are shares of company stock that you earn over time. They’re a reward for staying with your employer and contributing to its success. Your company grants you RSUs, and once they vest (usually in increments over several years), they become actual company stock you can sell or hold onto.
This kind of compensation is especially common in tech and startup environments and can be a major wealth-building tool—if you understand how to manage it well.
The Vesting Schedule and "Golden Handcuffs"
Most RSUs vest over several years, encouraging you to stay with the company. For example, you might be granted 300 RSUs in 2025 that vest over three years—100 per year in 2026, 2027, and 2028.
This creates a rolling accumulation of shares, often referred to as "golden handcuffs" because each new grant makes it harder to walk away. Leaving the company early means forfeiting any unvested shares.
Tax Planning Essentials: What You Need to Know
Taxes on RSUs can catch people off guard. Unlike other forms of compensation, RSUs are taxed as ordinary income when they vest—regardless of whether you sell them.
Unfortunately, most companies only withhold taxes at a flat 22% rate, which may not be enough if you’re in a higher tax bracket. That can leave you with a surprise tax bill.
Here’s what to do:
- Work with a CPA to estimate your actual tax liability
- Consider setting aside additional funds to cover taxes
- Explore adjusting your withholding or making estimated payments
If you're married and both spouses receive RSUs, it's even more important to coordinate your tax planning. Combined income can push you into a much higher bracket.
Diversifying Your RSU Holdings
It can be tempting to hold onto company stock, especially if the price is rising—but too much exposure is risky. A common rule of thumb is to keep your company stock under 10% of your overall investment portfolio.
Since you're taxed when RSUs vest, selling them immediately doesn’t add additional tax liability. Reinvesting the proceeds into a diversified portfolio helps reduce risk and builds a more balanced financial future.
Tip: Consider setting up a 10b5-1 plan, which automates stock sales after vesting. This can help avoid emotional decision-making and sidestep blackout periods during earnings season.
Career Transitions and RSUs
If you're thinking about switching jobs, your RSUs should be part of the financial equation. Know your vesting schedule, and understand what you’re walking away from.
When negotiating a new offer:
Ask for a sign-on bonus or RSU replacement
Clarify the structure and timing of new equity awards
Know the difference between RSUs and stock options (RSUs are a gift; stock options are the right to buy stock)
Spreading compensation across tax years can help you manage your bracket, especially if you're receiving a windfall from both jobs.
Final Takeaways
RSUs can help you build wealth—but only if you understand how they work and plan accordingly.
Know your vesting timeline
Plan for taxes beyond default withholding
Diversify your holdings
Don’t leave money on the table during job transitions
With thoughtful strategy, RSUs can be more than just a perk—they can become a core part of your financial future.
