Paying taxes on RSUs three times - am I getting triple taxed?
As someone who didn't grow up with much financial education, I'm really confused about how the taxes on my RSUs work. I could use some help understanding why it feels like I'm getting taxed multiple times. Here's what's happening: 1. When my RSUs vested, my company did a sell-to-cover to pay taxes 2. Then the RSUs showed up as income on my W2, and I paid income tax on them 3. Now I sold a couple of my remaining shares and I'm being told I need to pay taxes again Why am I paying taxes on these RSUs three separate times? This doesn't seem right. I was told by my company that sell-to-cover was the best option because I'd "pay tax on the current value and not have to later if I sold them." They made it sound like this would cover capital gains too, which I now realize was too good to be true. I don't understand why they appear on my W2 as income when I thought the sell-to-cover was handling the taxes. I've both lost the sell-to-cover portion AND paid income tax on what vested. And now with the sale, I'm paying taxes again (at least on gains). Can someone explain how these are represented on my 1099? I only see cost basis and proceeds listed there. Any help is really appreciated since I'm trying to figure this out on my own.

You're not actually being triple-taxed, though I completely understand why it feels that way! Let me break this down: 1. Sell-to-cover: This isn't a tax itself, but a mechanism where your company automatically sells enough shares to cover the withholding taxes due when RSUs vest. This is just withholding, like what happens with your paycheck. 2. W-2 reporting: When RSUs vest, they become income to you at the fair market value on the vesting date. This is reported on your W-2. The withholding from the sell-to-cover is credited against this tax obligation. You're not paying this twice - the withholding was just an estimate of what you'd owe. 3. Capital gains: When you sell shares later, you're only taxed on any appreciation since vesting. Your cost basis is the fair market value when they vested (what was reported on your W-2), so you're only taxed on gains above that amount. On your 1099, the cost basis should be the value of the shares when they vested. The proceeds are what you received from selling. You only pay capital gains tax on the difference.

•But if they sold shares to cover the taxes at vesting, why do I still have to pay income tax on the full value that shows up on my W2? Doesn't that mean I'm paying income tax twice? Also, on my 1099-B it doesn't clearly show what part is the original value and what part is gains. It just shows proceeds and cost basis. How do I know what portion is actually being taxed as capital gains?

•The shares that were sold to cover were just to handle tax withholding, similar to how your employer withholds taxes from your paycheck. That withholding gets credited against your total tax bill when you file your return. You're not paying income tax twice - the withholding is just an advance payment toward the income tax that will eventually be due on your W-2 income. On your 1099-B, the cost basis is the value of your shares when they vested (what was included as income on your W-2). The proceeds are what you received when you sold. The difference between these two numbers is your capital gain or loss, and that's the only amount being taxed in the third step. If your proceeds are higher than your cost basis, you have a gain. If lower, you have a loss.

I went through exactly the same confusion last year! After struggling to understand RSUs, I found this amazing tool called taxr.ai (https://taxr.ai) that helped me sort through all my stock compensation documents. It analyzes your W-2, 1099-B, and even your company's equity statements to give you a clear picture of what's happening with your RSUs. For me, the tool confirmed what the previous commenter explained - we're not actually being taxed three times. It showed me exactly how my sell-to-cover shares were just handling my withholding, how the vested value appeared on my W-2, and then calculated my actual capital gains when I sold some shares. The visual breakdowns really helped me understand the flow of money and taxes.

•Does taxr.ai work with multiple employers? I have RSUs from my previous job and my current one, and they each handled things differently. One did sell-to-cover and the other made me pay out of pocket for the taxes. Would the tool be able to handle both scenarios?

•I'm skeptical about using yet another financial tool. How does it actually access your tax documents? Is it secure? I'm always worried about giving my financial info to random sites.

•Yes, the tool works with multiple employers! I actually had RSUs from two different companies myself. It handles different tax withholding methods, whether they did sell-to-cover or if you paid the taxes yourself. You just upload the relevant documents from each employer. Regarding security, I was hesitant too. They use bank-level encryption and don't store your documents after analysis. You can upload PDFs directly or take photos of your documents, and the system just extracts the necessary information to do the calculations. I felt comfortable with it after reading their privacy policy and seeing they're focused specifically on stock compensation confusion.

I tried out taxr.ai after my skepticism and am honestly surprised how helpful it was. The tool immediately identified that my cost basis on my 1099-B matched the amount that was reported as income on my W-2, confirming I wasn't being double-taxed. It showed me a timeline view of my RSU vesting events, the associated withholding, and subsequent sales. The visualization made it crystal clear that sell-to-cover was just withholding (like from a paycheck), the W-2 reporting was the actual income tax event, and my later sale only triggered tax on the appreciation since vesting. What was most helpful was seeing exactly how much of my proceeds were actually taxable gains versus just recovering my already-taxed principal. Saved me hours of confusion!

If you're still confused after reading the explanations here, you might want to try contacting the IRS directly. I know it sounds terrible, but I finally got answers about my RSU situation by using Claimyr (https://claimyr.com) to get through to an actual human at the IRS. They have this video showing how it works: https://youtu.be/_kiP6q8DX5c I spent DAYS trying to get through the normal IRS phone line, just getting disconnected or waiting forever. With Claimyr, I got through in about 20 minutes and explained my RSU confusion to the agent. They walked me through exactly how the taxation works at each step and confirmed I wasn't being triple-taxed. They also explained how to properly read my 1099-B to identify what portion was actually subject to capital gains.

•Wait, how does this even work? The IRS never answers their phones. Are you saying this service somehow gets you to the front of the queue? That seems too good to be true.

•Sounds like a scam to me. Why would I pay some third party to call the IRS? And even if I do get through, most IRS agents don't understand the complexities of RSU taxation anyway. I talked to three different agents last year and got three different answers.

•It's not about getting to the front of the queue - they use a system that continuously redials until it gets through, then it calls you once it has an IRS agent on the line. I was skeptical too, but it works because it's just solving the "getting through" problem, not promising any special treatment once connected. You're right that not all IRS agents are experts on everything, but I got lucky with someone in their stock compensation department who was very knowledgeable. If you do call, I'd recommend specifically asking for someone who specializes in stock compensation or capital gains issues. You can always politely end the call and try again if you don't get someone knowledgeable right away.

I stand corrected about Claimyr. Despite my skepticism, I decided to try it yesterday after my accountant gave me conflicting information about my RSUs. The service actually worked! Got me through to an IRS specialist in about 30 minutes. The agent confirmed everything others have said here - the sell-to-cover is just withholding, not a separate tax. She also explained that my cost basis on the 1099-B should equal what was reported as income on my W-2, and I should only be paying capital gains tax on any appreciation after vesting. The agent even directed me to Publication 525 which has a section specifically about stock compensation that cleared up a lot of my confusion. Saved me from potentially overpaying my taxes because my accountant was calculating things incorrectly.

I went through the exact same thing last year! Just to add to what others have said - make sure your cost basis is reported correctly on your 1099-B. Sometimes brokers don't report the correct cost basis to the IRS for RSUs, which can make it look like your entire proceeds are gains (which would be bad). If the cost basis on your 1099-B doesn't match what was included in your W-2 income when the shares vested, you'll need to make an adjustment on your tax return. Look at Form 8949 - there's a code "B" you can use to indicate an adjusted basis. Also check if your broker is using "first-in, first-out" (FIFO) for calculating which shares were sold. This can affect your gains calculation if you received RSUs at different times with different vesting prices.

•Thank you for mentioning this! I just checked my 1099-B and I think this might be part of my problem. The cost basis seems lower than what I remember the shares being worth when they vested. How exactly do I use this Form 8949 to make the adjustment?

•You'll need to complete Form 8949 with your tax return. In column (a), enter the description of the property (your company stock). In columns (b) through (g), enter the information from your 1099-B. Then in column (g), enter the correct amount of gain or loss using your actual cost basis (the FMV on vesting date). In column (f), check box B to indicate you're reporting a basis different from what was reported to the IRS. You'll also need to attach an explanation statement to your return that explains why you're adjusting the basis - something like "Adjusting cost basis to fair market value at RSU vesting date, which was included as income on my W-2.

One thing nobody has mentioned yet - check if your company has an ESPP (Employee Stock Purchase Plan) in addition to the RSUs. Those have completely different tax rules and might be adding to your confusion if you're participating in both programs. Also, some companies provide statements that break down all your equity compensation events for the year. Ask your HR or benefits department if they provide a supplemental equity statement that might help clarify things.

•Great point! I mixed up my RSUs and ESPP shares last year and almost reported everything wrong. ESPP shares are WAY more complicated tax-wise because of the discount and lookback provisions. What helped me was downloading a detailed transaction history from my company's stock administrator (like E*TRADE, Fidelity, Morgan Stanley, etc.) and looking at the transaction types. RSUs will show as "RSU Release" or similar when they vest, while ESPP purchases will show as "ESPP Purchase.
