I'm currently going through the exact same Error 6000 situation and this entire thread has been absolutely invaluable! Got my identity verification letter three days ago and have been hitting the same wall every time I try to access the online verification system. It's incredibly frustrating that they send you an official government letter demanding you complete something online, but then their own system blocks you from doing exactly what they're requesting. Based on everyone's detailed experiences here, I now understand this is unfortunately a very common issue where the verification request and the system error are directly connected - your account gets flagged for manual review (which triggers the letter), but that same flag prevents online access until someone manually removes it. I'm definitely going to call the 800-830-5084 Identity Verification line first thing tomorrow morning at 7am EST with all my documents ready (SSN, verification letter, last year's return, address info). The consistent success stories from people who reached that specific department instead of the general help desk give me real hope that this bureaucratic nightmare actually has a solution. Thanks to everyone who took the time to share such detailed guidance - this community knowledge is a lifesaver when dealing with government systems that seem designed to confuse and frustrate taxpayers! I'll update once I get through and hopefully join the ranks of people who got this resolved quickly once they reached the right department.

I've been following this thread as someone who went through Error 6000 about 6 months ago, and I wanted to add a few things that might help others: First, you're absolutely right to focus on the 800-830-5084 Identity Verification line - that's the ONLY number that can actually remove these account blocks. I wasted days calling the general help desk before learning this. One thing I haven't seen mentioned much is that Error 6000 can sometimes be triggered by things you wouldn't expect - in my case, it was because I had claimed education credits for the first time and their system flagged it as unusual activity. So it's not just address changes or obvious red flags. When you do get through to an agent, they'll likely ask you to verify information from multiple years of returns, not just the most recent one. Have at least your last 2 years of returns handy if possible. Also, once they remove the block and you complete the online verification, screenshot everything and save confirmation numbers. I had to call back a month later because somehow the flag got re-added to my account (probably a system glitch), but having those confirmation numbers made the second call much shorter. The whole system is absolutely broken, but the identity verification specialists really do know how to fix these issues quickly once you reach them. Good luck to everyone dealing with this mess!

I just wanted to share my recent experience to add to all these helpful stories! I received a "TCS TREAS 449" deposit for $1,247 just two weeks ago and was completely baffled, especially since I had already gotten my regular refund back in March. After reading through this amazing thread, I followed everyone's advice and checked my IRS online account. It turns out it was an adjustment to my Child and Dependent Care Credit - apparently when they processed my return, their system calculated that I was eligible for significantly more than what I had originally claimed based on my dependent care expenses. What's really interesting is that I thought I had calculated everything correctly, but it seems like the IRS has access to additional verification data that allowed them to increase my credit amount. The online transcript showed exactly how they recalculated it and when the adjustment was processed. Like so many others mentioned, no advance notice whatsoever - just the deposit appearing out of nowhere, then the CP12 explanation letter arrived about 10 days later. It's definitely a weird way to handle things from a customer service perspective, but I'm certainly not complaining about unexpected money that's rightfully mine! For anyone still worried about these deposits: every single experience shared here has been positive, which really shows that the "TCS TREAS 449" code is reliable for legitimate IRS payments. Don't stress about it - just check your online account for peace of mind and enjoy your unexpected windfall!

I completely understand your confusion about this unexpected deposit! As someone who's also dealt with mysterious "TCS TREAS 449" deposits, I can tell you that reading through all these experiences has been incredibly reassuring. Based on everything shared here, it's clear that this Treasury code is specifically used for legitimate tax refunds and credit adjustments. Since you filed in February and already received your regular refund, this is almost certainly an automated adjustment where the IRS reviewed your return and found you qualified for additional credits. The amount of $837.42 seems very reasonable for a credit recalculation - could be related to the Child Tax Credit, American Opportunity Credit, or Earned Income Credit that you mentioned claiming. The IRS has been doing systematic reviews lately and frequently finds that taxpayers didn't claim everything they were entitled to. I'd definitely recommend checking your IRS online account first like everyone suggested - that's going to give you immediate answers about what triggered this adjustment. You can view your account transcript there which will show exactly what the payment represents and when it was processed. Don't stress too much about this! Based on all the positive experiences shared in this thread, you can feel confident this is probably legitimate money you're entitled to keep. The Treasury 449 code is specifically reserved for official tax payments, so that's actually a very good sign. You should get an explanation letter in the next week or two, but checking online will give you peace of mind right away. It's actually pretty nice when the IRS finds extra money for us instead of the other way around!

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.

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.

New member here and unfortunately dealing with the exact same nightmare! Filed my NY return on January 31st and been stuck in that completely useless "further review" status for about 5 weeks now. Was really counting on that refund to help cover some unexpected vet bills but looks like I'm joining the endless waiting game with everyone else. This thread has been such a godsend - I was starting to think I somehow screwed up my return but now I see it's just NY being completely dysfunctional this year. Huge thanks to @Sean Doyle for actually calling and getting that realistic (though brutal) 10-16 week timeline from them. At least now we have concrete expectations instead of that absolutely worthless "further review" message that tells us literally nothing. Definitely going to try calling that 518 number this week even though 90+ minutes on hold sounds like pure torture. Also thinking about trying that taxr.ai tool everyone keeps mentioning since anything has to be more informative than refreshing NY's garbage website hoping for updates that never come. Thanks @Lily Young for creating this thread - it's been infinitely more helpful than any official NY resource! Here's hoping we all start seeing some actual movement soon because this whole situation is absolutely insane 😤

Newcomer here and dealing with this exact same mess! Filed my NY return on February 12th and it's been stuck in that infuriating "further review" status for about 2.5 weeks now. Was really hoping to use that refund for some overdue credit card payments but looks like I'm settling in for the long haul with everyone else here. This thread has been incredibly helpful - I was starting to worry I made some mistake on my return but clearly this is just NY's complete system failure this year. Really grateful to @Sean Doyle for actually calling and getting that realistic 10-16 week timeline from them. It's absolutely brutal but at least gives us concrete expectations instead of that completely useless "further review" message that tells us nothing useful. Definitely going to try calling that 518 number this week even though spending hours on hold sounds miserable. Also considering that taxr.ai tool everyone keeps mentioning since literally anything has to be more informative than NY's worthless website. Thanks @Lily Young for starting this thread - it's been way more valuable than any official NY resource! Here's hoping we all start seeing some actual progress soon because this whole situation is beyond frustrating 😩

quick questions - do the payments actually need to match the profitability by quarter or can i just divide my total estimated taxes for the year into 4 equal payments? my s-corp has really seasonal income so some quarters have way more profit than others.

Great question about S Corp quarterly payments! Just to add some clarity - you're absolutely right to be thinking about this carefully. The key thing to remember is that as an S Corp owner, you wear two hats: employee (if you take a salary) and owner/shareholder. From the business account, you should pay: - Payroll taxes for your salary (employer portion of FICA, unemployment taxes, etc.) - Any business-specific taxes like state franchise fees From your personal account, you should pay: - Estimated quarterly payments for the income tax on your share of the S Corp profits - Your portion of self-employment tax equivalent (though S Corp profits aren't subject to SE tax, which is one of the benefits) Since this is your first profitable quarter, make sure you're also paying yourself a reasonable salary if you haven't been already - the IRS expects S Corp owner-employees to take W-2 wages before distributions. Congrats on the profit, and keep that business/personal separation clean for your records!
