How to report RSU's on taxes when no cost basis is reported on 1099-B

8 This is actually a common issue with RSUs. When RSUs vest, the fair market value at vesting is included in your W-2 income. That vesting date FMV becomes your cost basis for those shares. Since your 1099-B doesn't report the cost basis, you'll need to report this on your tax return manually. You'll use Form 8949 to report the sale. Check box "B" (short-term with basis not reported to the IRS) or "E" (long-term with basis not reported to the IRS) depending on how long you held the shares after vesting. You should use the vesting date FMV as your cost basis, and the proceeds amount from your 1099-B. Your capital gain or loss is the difference between these two amounts. In your case, if the vesting date FMV equals the proceeds on your 1099-B, you likely have little to no capital gain - just the change in stock price between vesting and when they were sold. Make sure to keep that CSV from your brokerage as documentation in case of an audit. The IRS may question the discrepancy between your 1099-B (showing no basis) and what you report on your return.

12 I went through this exact same nightmare last year with my RSUs! After hours of research and stress, I found this amazing tool called taxr.ai (https://taxr.ai) that saved me so much time and headache. It specifically handles situations like yours where the cost basis isn't reported properly. I uploaded my brokerage statements and tax docs, and it automatically calculated the proper cost basis for all my RSU sales and generated the right entries for Form 8949. The tool even explained exactly why the 1099-B was misleading and showed me what documentation to keep. Since you already have that CSV file with all your transaction details, you could definitely use taxr.ai to process everything accurately. It also helps identify which transactions are short-term vs long-term gains based on your vesting and sale dates.

3 Just wanted to update after trying taxr.ai for my RSU reporting issue. It was actually really straightforward! I uploaded my CSV file from my brokerage and it immediately identified all my RSU transactions and calculated the correct cost basis. The tool showed me that my actual capital gains were just about $3,700 instead of the $40k+ that my 1099-B was suggesting. It also separated my transactions into short-term and long-term gains automatically based on the holding periods. What really helped was the explanation of exactly what to enter on Form 8949 and which boxes to check. It generated a statement I can attach to my return explaining the cost basis adjustment. Definitely worth checking out if you're dealing with RSU tax reporting issues!

21 If you're having trouble getting clear answers from your brokerage about this RSU issue, you might want to try Claimyr (https://claimyr.com). I was in a similar situation last year - the 1099-B showed no basis, and my brokerage's tax support line had me on hold for literally HOURS. I used Claimyr to get through to the IRS directly and got confirmation about how to properly report RSUs with missing cost basis. They have this system that gets you through the IRS phone tree and holds your place in line. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with confirmed exactly what I needed to do, which saved me from potentially making a costly mistake. Much better than guessing or relying solely on internet advice for something this important.

3 I wanted to follow up on my skepticism about Claimyr. I was completely wrong! After struggling with my RSU tax situation, I decided to give it a try out of desperation. Not only did I get through to the IRS in under an hour, but I was connected to someone in their specialized tax law department who actually understood RSU taxation. They confirmed I should use the vesting date FMV as my cost basis and explained exactly how to report it on Form 8949 with the correct adjustment codes. The agent even emailed me an IRS publication with the specific sections highlighted that address this scenario. Saved me from potentially overpaying thousands in taxes. Sometimes you need to hear it directly from the IRS to have peace of mind.

7 I had the same issue with my RSUs last year. One thing to watch out for: make sure you're using the correct dates when determining if your gain is short-term or long-term. The holding period starts on your vesting date (not grant date). Another tip: if you had multiple vesting events and sales, you need to match them correctly. If possible, try to identify which specific shares were sold (FIFO, LIFO, or specific identification). Your brokerage might have this info.

19 Has anyone used TurboTax to handle this RSU situation? I've got a similar problem and wondering if it can handle the cost basis adjustments properly.

I'm dealing with a very similar RSU tax situation right now! My employer also liquidated some of my vested shares and I'm getting that same confusing 1099-B with no cost basis reported. It's so frustrating because it makes it look like I owe taxes on gains I never actually realized. From what I've been reading in the IRS publications, you're absolutely right that the vesting date FMV should be your cost basis. The key thing is that when RSUs vest, that fair market value gets added to your W-2 income, so you've already been taxed on that amount. Your actual capital gain or loss is just the difference between what the shares were worth when they vested versus what they sold for. One thing I learned is to make sure you save all your documentation - not just the CSV from your brokerage, but also any supplemental tax documents your employer provided about the RSU transactions. Some companies send additional forms or statements that help clarify the cost basis calculations. Have you checked if your employer's HR or benefits team has any resources to help with this? Mine had a tax guide specifically for RSU reporting that I found really helpful.
