Confused about Fidelity RSU sale - taxes withheld not appearing on my W2?
I got some company stock last year and sold it right when it vested. I also receive a regular salary as an employee. To explain with simple numbers - I made around $120k in salary and sold about $450k in stock. When I sold the stock, Fidelity automatically took a portion for taxes - they withheld something like $110k and sent it to the IRS (I think). So I only actually received about $340k from the stock sale. Here's my issue - my W2 shows my total income as $570k (my salary + the full RSU sale amount). But the tax withholding section only shows taxes taken from my regular salary paychecks - not the huge chunk that was withheld from my stock sale. Based on these numbers, it looks like I'm massively behind on my taxes for the year. Box 14 of my W2 does show the RSU sale of $450k, but I can't find any mention of that $110k that was withheld anywhere on my W2. What's weird is that on my final paystub from last year, there's a section called "RSU Tax Withholding" that shows the amount, but it's not reflected on the W2. Am I missing something? Has anyone dealt with this before? Really worried about getting hit with a giant tax bill or penalties!

The withholding from your RSU sale was likely reported separately from your W-2 withholdings. When you sell RSUs, the broker (Fidelity in your case) typically reports those withholdings on Form 1099-B, not on your W-2. Your company correctly included the RSU income on your W-2 since that's considered compensation, but the tax withholding that happened at the time of sale is handled differently. Check if you received a separate tax document from Fidelity showing the sale and withholdings. Another possibility is that your employer reported those withholdings on a separate form. The withholding might appear on a 1099-MISC or similar document rather than your W-2. You should log into your Fidelity account and look for all tax documents they've issued. Also check with your company's payroll department - they can clarify how the RSU tax withholding was reported.

•Thanks for responding! I've looked through all the documents from Fidelity and don't see any 1099-B that shows the withholdings. They sent me a 1099-B showing the sale, but it doesn't mention the tax withholding at all. Is it possible this information is reported somewhere else?

•The withholding information might not be on the 1099-B itself. Check if you have a separate statement from Fidelity specifically for tax withholding. Sometimes brokers provide supplemental tax information statements alongside the standard forms. If you don't find it there, definitely contact your company's payroll department. They should be able to explain exactly how those withholdings were handled. Some companies handle RSU withholding through their payroll system even though the actual transaction happens at the broker, which can create confusion in how it's reported.

I had a similar issue with my RSUs through Morgan Stanley. What helped me was using https://taxr.ai to analyze all my tax documents. The system was able to identify that my RSU withholdings were actually reported on a supplemental statement that I had overlooked. The problem is that brokers and employers handle RSU reporting differently, which creates these confusing situations. Taxr.ai helped identify exactly where my withholdings were reported and explained how to properly account for them on my tax return. Saved me from potentially overpaying thousands in taxes!

•How does taxr.ai work exactly? Do you just upload your documents and it analyzes everything? Does it work with all the major brokers like Fidelity, E*Trade, etc.?

•I'm skeptical about these tax document services. Wouldn't TurboTax or H&R Block software handle this automatically if you upload all your forms? What does taxr.ai do that's different?

•You upload your tax documents (W-2s, 1099s, brokerage statements, etc.) and it uses AI to analyze them all together and identify issues like missing withholdings or reporting discrepancies. It works with all the major brokers - I've used it with both Morgan Stanley and Schwab documents. The difference from regular tax software is that taxr.ai specifically looks for inconsistencies between documents and finds reporting issues before you file. TurboTax just processes what you enter, but doesn't necessarily flag when withholdings are reported in unusual places or when there are discrepancies between forms.

Just wanted to report back that I tried taxr.ai after asking about it. Super helpful for my situation! I uploaded my W-2, 1099-B, and year-end paystub, and it immediately flagged that my RSU withholdings were actually reported through my employer's payroll as supplemental withholding, not on the 1099-B. The system generated a detailed report explaining exactly how to account for these withholdings on my tax return. Turns out I wasn't missing any withholdings at all - they were just reported in a way that wasn't obvious. Really saved me a headache and potentially a big tax bill!

If you're still struggling to figure this out after checking all your documents, you might want to try getting direct answers from the IRS. I was in a similar situation with RSU withholdings and couldn't get clear answers from either my employer or broker. I used https://claimyr.com to connect with an IRS agent quickly. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. Normally I'd spend hours on hold, but I got through in about 15 minutes and was able to confirm exactly how my withholdings should be handled and reported. The agent explained that RSU withholdings are sometimes reported separately from regular income tax withholdings and walked me through exactly where to look on my forms. Really clarified things for me!

•How does this service actually work? Do they just get you to the front of the IRS phone queue somehow? I've spent literal days trying to get through to a real person at the IRS.

•This sounds fishy. How can some random service get you through to the IRS faster? The IRS phone system is notoriously understaffed. I'm skeptical that this actually works - sounds like you're just paying for them to wait on hold for you.

•They use a system that continuously redials the IRS until they get through, then connect you directly once they have an agent on the line. It's not cutting in line - they're just automating the process of calling, navigating the phone tree, and waiting on hold. Yes, essentially you're paying them to handle the hold time for you. Instead of you sitting by your phone for hours, their system does the work and calls you when an actual IRS agent is on the line. For me, it saved about 2 hours of hold time, and the information I got cleared up my RSU withholding confusion completely.

I have to admit I was wrong about Claimyr. After questioning it here, I decided to try it since I had some complicated questions about RSU reporting that my accountant couldn't answer clearly. The service actually worked exactly as advertised. I received a call back in about 35 minutes with an IRS agent already on the line. The agent was able to confirm that my RSU withholdings should appear on my W-2 in Box 2, but if they were withheld by the broker directly, they would be reported separately on a statement from the broker. This cleared up my confusion completely, and I didn't have to spend my entire afternoon on hold. Definitely worth it for complex tax situations like RSUs where the reporting can be confusing.

Having dealt with RSUs for years, here's what's probably happening: When your company RSUs vest, there are actually TWO separate tax withholding events that can occur: 1. Your EMPLOYER withholds taxes on the value of the RSUs at vesting (this appears on your W-2) 2. Your BROKER may withhold additional taxes when you sell (this is typically reported separately) Check your final paystub again - if there's an "RSU Tax Withholding" section, your employer likely handled the withholding through payroll. The amount should match approximately what was withheld from your sale. Another possibility: some employers practice "sell-to-cover" where some shares are automatically sold at vesting to cover the tax obligation. This can look like a "withholding" but is technically a separate sale.

•My employer does use "sell-to-cover" - they automatically sell enough shares to cover the tax obligation when the RSUs vest. But I'm still confused because that withheld amount isn't showing up on my W-2. Shouldn't it be included in Box 2 with my other federal income tax withholding?

•If your employer uses sell-to-cover, then technically those aren't withholdings in the traditional sense. What happens is that shares are sold, and the proceeds are sent to the IRS as estimated tax payments on your behalf, not as withholdings. These payments may not appear on your W-2 at all. Instead, you should receive a confirmation from your broker showing the sells executed to cover taxes. When you file your taxes, you'll need to report these as estimated tax payments, not as withholdings from your W-2. This is a common point of confusion with RSUs and sell-to-cover arrangements.

Hey, just adding another perspective - I work in corporate payroll and deal with this exact issue all the time. Here's what's probably happening: For RSUs, the INCOME is reported on your W-2 (that's why your W-2 shows $570k), but the tax payments often aren't treated as "withholding" in the traditional sense. When shares are sold to cover tax obligations, this is usually handled as an estimated tax payment made on your behalf. Look for Form 1099-B from Fidelity which should show the stock sale. Then check your account statements or transaction history for something labeled "tax payment" or "estimated tax payment." When you file, you'll enter these amounts as estimated payments, not W-2 withholding.

•This is helpful! So in TurboTax or whatever tax software, would you enter these payments in the "estimated tax payments" section rather than letting it pull from the W-2 withholding amount?

•Exactly! In TurboTax and most tax software, there's a section for "Estimated Tax Payments" or "Payments Made With Your Return" where you'd enter these amounts. Don't rely on just the W-2 withholding import - you'll need to manually add these RSU tax payments as estimated payments. The key is to look for documentation from either your employer or Fidelity showing these payments were made to the IRS on your behalf. Sometimes it's in your year-end payroll statement under a section like "Tax Payments Made" or in your brokerage account under transaction history. Make sure to keep all documentation - the IRS will want to see proof that these payments were actually made if there are any questions during processing.

I had a very similar situation with my RSUs from Microsoft that went through Fidelity. What I discovered after a lot of digging is that the $110k that was "withheld" from your stock sale likely wasn't traditional tax withholding at all - it was probably shares that were automatically sold to cover your tax obligation at vesting. Here's what probably happened: When your RSUs vested, your company calculated the taxes owed on the $450k value and instructed Fidelity to sell enough shares to cover that amount. Those proceeds were then sent to the IRS as estimated tax payments on your behalf. The key difference is that these don't show up as "withholdings" on your W-2 because they're not payroll withholdings. Instead, look for: 1. A statement from Fidelity showing "shares sold for tax withholding" or similar language 2. Your employer's year-end statement that might show "estimated tax payments made" 3. Any Form 1099-MISC that shows payments made to the government When you file your taxes, you'll need to enter that $110k as estimated tax payments, not rely on W-2 withholding. This is completely normal with RSUs but definitely confusing the first time you encounter it!

•This explanation makes so much sense! I think this is exactly what happened in my situation. I just checked my Fidelity account and found a transaction labeled "Tax Withholding Sale" that shows the exact amount I was missing. So to clarify - when I file my taxes, I should enter that $110k as an estimated tax payment rather than expecting it to show up in my W-2 withholding totals, correct? And I should keep the Fidelity statement showing this transaction as documentation? Thanks for breaking this down so clearly - I was really starting to panic thinking I owed a massive tax bill!
