Difference between W-8BEN and W9 forms for H1B visa holder - which one to submit to my bank?
Hey everyone, I recently moved to the US on an H1B visa and I'm working at a government research facility. Just got a letter from my bank asking me to fill out either a W-8BEN or W9 form and send it back to them. I'm confused about which form I should complete. From what I understand, these are tax forms, but my employer is already deducting income tax from my paycheck every month. Does anyone know which form is appropriate for my situation as a non-US resident on an H1B working at a government institution? I don't want to mess anything up with my taxes or banking situation. Thanks in advance for any help!

You should definitely fill out the W-8BEN form. This is the correct form for non-US residents/non-citizens. The W-9 is specifically for US citizens and resident aliens (green card holders or those who pass the substantial presence test). The W-8BEN certifies that you're a foreign person not subject to certain US tax withholding. Your bank needs this on file to properly report your account to the IRS. Even though your employer is already withholding taxes from your salary, the bank needs this documentation separately for their own reporting requirements. As an H1B visa holder, you're generally considered a non-resident alien for tax purposes in your first year, unless you meet the substantial presence test. The bank is just doing their due diligence to ensure they have the proper documentation for your account.

•Thanks for the explanation, but I'm a bit confused - if OP is working in the US on an H1B visa, aren't they considered a resident alien for tax purposes? I thought working on an H1B would automatically make someone a resident alien since they're living in the US. Is that not right?

•The H1B status alone doesn't automatically make someone a resident alien for tax purposes. It depends on how long they've been physically present in the US. For tax purposes, someone becomes a resident alien if they meet the "substantial presence test," which generally means they've been in the US for 183 days or more during the current year, or through a weighted formula counting days over a 3-year period. If this is their first year on H1B in the US, they would typically be considered a non-resident alien unless they meet that test. That's why the W-8BEN is most likely the appropriate form. However, if they've been in the US long enough to meet the substantial presence test, they might need to file as a resident alien, which could affect which form is appropriate.

After struggling with similar tax document confusion when I came to the US on a work visa, I found this amazing tool called taxr.ai (https://taxr.ai) that literally saved me from making a huge mistake with my tax documentation. It analyzes your specific visa situation and tells you exactly which forms you need to file. I uploaded the letter from my bank and my visa details, and it immediately clarified that as an H1B holder I needed the W-8BEN, not the W-9. It also explained why the bank was asking for this documentation even though my employer was already withholding taxes. The best part was that it explained everything in simple language and gave me step-by-step instructions for filling out the form correctly. No more tax anxiety!

•Does this tool actually explain how to fill out all the fields on the W-8BEN? I'm in a similar situation but I'm confused about the tax treaty benefits section and whether I should be claiming any treaty benefits. Does it cover that kind of specific detail?

•Sounds interesting but I'm skeptical about sharing my personal tax info with some random website. How secure is it? I mean, these are pretty sensitive documents with my SSN and everything. Do they store your data or is it just an analysis tool?

•The tool definitely walks you through every field on the W-8BEN, including the tax treaty section. It asks about your country of citizenship and then tells you if there's an applicable tax treaty and what benefits you might be eligible for. It even explains which parts you can leave blank if they don't apply to you. As for security concerns, I was worried about that too at first. They use bank-level encryption and don't store your actual documents after analysis. They have a whole section explaining their security measures and privacy policy. You can also use it without uploading actual documents by just inputting your visa type and answering questions if you're uncomfortable sharing documents.

Just wanted to follow up about taxr.ai that someone mentioned earlier. I was super skeptical at first about sharing any tax info, but I was desperate with my W-8BEN form so I gave it a try. Honestly, I'm glad I did. The site actually doesn't store your documents, and they explain exactly what information they need and why. I used it to figure out my tax residency status based on my entry dates to the US and my visa type. It confirmed I needed the W-8BEN and walked me through every box on the form. The specific guidance on the tax treaty section was incredibly helpful - turns out I was eligible for certain benefits from my country's tax treaty that I had no idea about. Definitely saved me from leaving money on the table.

If you're struggling to get through to the IRS to confirm which form you should file (like I was for WEEKS), try Claimyr.com (https://claimyr.com). They got me connected to an actual IRS agent in under 15 minutes when I had been trying for days on my own. I had the exact same confusion between W-8BEN and W-9 with my bank when I first got here on my H1B. The IRS agent I spoke to confirmed I needed the W-8BEN and explained exactly how to fill it out correctly for my specific situation. They also explained how my tax situation would change if I stayed in the US long enough to become a resident alien for tax purposes. Check out their demo video to see how it works: https://youtu.be/_kiP6q8DX5c. Honestly, it was worth it just to stop the anxiety of wondering if I was doing something wrong.

•How exactly does this service work? Do they just call the IRS for you? Couldn't I just do that myself? The IRS phone lines are definitely a pain but I'm not sure I understand what this service actually does.

•Yeah right. Nobody gets through to the IRS in 15 minutes. I've tried calling them multiple times about my tax situation and the shortest wait time I've had was 2 hours before the call dropped. This sounds like a scam to me.

•They don't just call for you - they use some kind of technology that navigates the IRS phone system and holds your place in line. When they actually reach an agent, you get a call to connect with them. It basically eliminates the hours of waiting on hold. No, this isn't a scam. I was skeptical too, but the difference is they have a system that can stay on hold indefinitely and navigate all those annoying phone menus. I tried calling myself multiple times and always gave up after an hour on hold. With their service, I got a call back when they reached an agent, and I was connected immediately. The whole process took about 15 minutes from when I signed up until I was talking to a real IRS person.

I need to follow up about the Claimyr service someone mentioned. I was the one who called it a scam because it sounded too good to be true. Well, I was absolutely wrong and I owe them an apology. After struggling for weeks to get through to the IRS about my W-8BEN vs W-9 confusion, I got desperate and tried it. Unbelievably, I was connected to an actual IRS agent in about 17 minutes. The agent confirmed I needed the W-8BEN as an H1B holder and walked me through the entire form. What would have been another day wasted on hold turned into a 20-minute productive call that solved my problem. The service actually works exactly as advertised. Crazy to think how many hours of my life I wasted trying to do this myself.

Just to add another perspective - I'm also on H1B and had to fill these forms when I opened my bank account. The key difference is: W-8BEN: For non-US citizens/residents who DON'T live in the US most of the time W-9: For US citizens, permanent residents, or non-citizens who DO pass the substantial presence test Since you're already working here on H1B and have been for some time (sounds like), you might actually need the W-9, not W-8BEN. It depends on how long you've been physically present in the US. Check if you pass the substantial presence test: count all days in current year + 1/3 of days in previous year + 1/6 of days from year before that. If it's 183+ days, you're a resident alien for tax purposes and need the W-9.

•Wait, this contradicts what the first commenter said about needing the W-8BEN. Now I'm even more confused! So which is it? W-8BEN or W-9? Does it depend on how long OP has been in the US on the H1B?

•You're right that it might seem contradictory, but that's because tax residency can be complicated. The first commenter assumed the person was new to the US, but we don't know that for sure. The key factor is the substantial presence test. The default for a new H1B holder is to use the W-8BEN. However, if they've been in the US long enough to pass the substantial presence test (generally 183+ days using that weighted formula I mentioned), then they would be considered a resident alien for tax purposes and would need the W-9 instead. This often happens in the second year of being on an H1B.

Does anyone know if filling the wrong form will cause issues with the IRS? I think I may have accidentally filled out a W-9 instead of W-8BEN when I first arrived. Been on H1B for about 7 months now.

•You should contact your bank ASAP and ask to correct it. Filing the wrong form could potentially lead to incorrect tax withholding. If you've only been here 7 months, you're likely still a nonresident alien for tax purposes, so the W-8BEN would be the correct form.

I went through this exact same situation when I first arrived on my H1B! The confusion is totally understandable because both forms deal with tax documentation, but they serve different purposes. As others have mentioned, the key is determining your tax residency status. Since you mentioned you "recently moved" to the US, you're most likely still considered a non-resident alien for tax purposes, which means you should fill out the W-8BEN form. The bank needs this form regardless of what your employer is doing with payroll taxes - these are separate requirements. Your employer withholds income tax from your salary, but the bank needs the W-8BEN to properly report any interest income from your accounts to the IRS and to determine if they need to withhold any taxes on that interest. One thing to keep in mind: if you stay in the US long enough to pass the substantial presence test (usually by your second year), your tax status will change to resident alien, and you'll need to update your bank documentation to a W-9 at that point. For now, go with the W-8BEN, but make sure you understand which country's tax treaty benefits (if any) you might be eligible for when filling out that section of the form.

•This is really helpful! I'm in a similar situation as the original poster and your explanation about the bank needing separate documentation from what the employer does makes it much clearer. One quick question - when you mention understanding which country's tax treaty benefits you might be eligible for, is there an easy way to figure that out? I'm from Canada and I have no idea if there are any benefits I should be claiming on the W-8BEN form. I don't want to miss out on something I'm entitled to, but I also don't want to claim something incorrectly. Also, do you happen to know if the bank will notify you when your tax status changes and you need to switch from W-8BEN to W-9, or is that something you need to keep track of yourself?

•Great question about the Canada-US tax treaty! Yes, there are definitely benefits you should be aware of. The US-Canada tax treaty has provisions that can reduce or eliminate withholding taxes on certain types of income, including interest from bank accounts. For the W-8BEN form, you'll want to look at Article XII of the US-Canada tax treaty, which typically allows for reduced withholding on interest income. You should claim treaty benefits on line 9 of the W-8BEN by writing "Canada" as your country of residence and referencing the specific article that applies to your situation. As for the bank notifying you about status changes - unfortunately, no, they won't track this for you. It's your responsibility to monitor your days in the US and update your forms when your tax status changes. I'd recommend keeping a simple calendar or spreadsheet to track your presence. Most people on H1B visas become resident aliens for tax purposes sometime in their second year in the US. When that happens, you'll need to proactively contact your bank to submit a new W-9 form to replace the W-8BEN. The IRS takes tax residency status seriously, so it's worth staying on top of this!

I went through this exact same confusion when I first arrived on my H1B visa! The good news is that you're asking the right questions before submitting anything. Based on what you've shared - that you "recently moved" to the US on an H1B - you should almost certainly fill out the **W-8BEN form**. Here's why: The W-8BEN is for non-resident aliens (which you likely are in your first year), while the W-9 is for US citizens and resident aliens. Your tax residency status is determined by the "substantial presence test," not just your visa type. A few important points: - This bank requirement is completely separate from your employer's payroll tax withholding - The bank needs this form to properly report any interest income from your accounts to the IRS - Even though your employer is handling income tax, the bank has its own reporting obligations **Pro tip:** When filling out the W-8BEN, don't forget to check if your home country has a tax treaty with the US that could reduce withholding on interest income. Many countries do, and you don't want to leave money on the table! Also, keep track of your days in the US because you'll likely need to switch to a W-9 form once you become a resident alien for tax purposes (usually in your second year). The bank won't remind you of this - it's your responsibility to update them. Hope this helps clear things up! The tax system here can be overwhelming at first, but you're being smart by asking questions before acting.

•This is such a comprehensive explanation, thank you! I'm actually in my first month on H1B and was completely overwhelmed by this form request from my bank. Your point about the substantial presence test is really helpful - I had no idea that's how tax residency is determined. Quick question about the tax treaty benefits you mentioned - is there a reliable way to look up what specific benefits my country might have? I'm from Germany and I want to make sure I'm not missing out on any reductions I'm entitled to. Also, do you know if there are any penalties for initially filing the wrong form and then having to correct it later? The tip about tracking days in the US is gold - I'll definitely start keeping a spreadsheet. Better to be prepared for when I need to switch forms rather than scrambling later!
