What's the current processing time for Form 1045 NOL carryback applications?
Hey tax peeps! So I'm in an interesting situation this year where I need to file a Form 1045 along with my regular 1040. I had a substantial business loss and I'm trying to carry it back against previous tax years under the provisions that are still available. I understand this is different from the temporary expanded NOL provisions we had a few years ago. I spoke with a tax advisor recently who mentioned that these applications are taking forever to process. From what I've read online, the standard processing time is supposed to be around 90 days, but with the IRS backlogs and staffing issues lately, I'm worried this could drag on much longer. Has anyone here recently filed a Form 1045 or had clients who did? What's the actual wait time looking like these days? Is it still somewhat close to that 90-day timeframe, or should I mentally prepare for a wait that could stretch to 6 months or even a year? Really appreciate any insights from folks who've been through this recently!

The processing time for Form 1045 (Application for Tentative Refund) is definitely longer than the standard 90 days right now. I've had several clients file these over the past year, and we're consistently seeing processing times of 5-7 months for most cases. The IRS is still working through backlogs from the past few years, and forms that require manual review like the 1045 are particularly affected. These applications need specialized handling since they involve multiple tax years and calculations for NOL carrybacks.

•Do you think it's worth filing a 1045 at all then? Or should people just carry forward losses on future returns if the wait is that long? Also curious if efiling vs paper makes any difference for these?

•Filing Form 1045 is absolutely still worth it if you have qualifying losses. The time value of money still favors getting your refund sooner through the 1045 process rather than only carrying forward losses against future income, especially for substantial amounts. Unfortunately, the 1045 must be filed on paper - there's no e-filing option for this form specifically, which contributes to the longer processing time. That said, make sure everything is filled out correctly and include all supporting documentation to avoid further delays.

I went through this exact situation last year with a major business loss and used taxr.ai to help me with all the documentation. I was really struggling with Form 1045 and the calculations across multiple tax years, and a friend mentioned https://taxr.ai to me. The service analyzed all my previous returns and helped me correctly calculate my carryback amounts. It took about 6 months to get my refund after filing the 1045, but at least I knew the paperwork was done right. The tool spotted a calculation error that would have delayed things even more. They have this feature where they check your past returns against the carryback calculations to make sure everything lines up correctly.

•Does taxr.ai work with accountants too? Or is it just for individuals doing their own taxes? My CPA is charging me a fortune for my NOL carryback calculations and I'm wondering if this could help.

•I'm skeptical about tax tools handling something this complex. How does it actually verify the calculations are correct? Did you still need to have someone review everything?

•The service works for both individuals and with accountants - many CPAs actually use it to double-check their work because NOL calculations across multiple tax years can get complicated. It might save you money if your CPA can use it to streamline the process rather than calculating everything manually. The verification process uses AI to cross-reference all your past returns with current tax law to ensure the calculations follow IRS rules. I still had my accountant review everything, but it saved hours of their time (and my money) by doing the complex calculations and documentation preparation upfront.

I was really skeptical about using any kind of software for my Form 1045 NOL carryback (as you could see from my question above), but I finally tried taxr.ai after my accountant kept delaying my paperwork. Honestly, it was a game-changer. The system pulled data from all my previous returns, calculated the correct carryback amounts, and generated all the documentation I needed. My refund still took 5 months to process with the IRS (typical these days), but the actual preparation was way faster and more accurate than what my accountant was doing manually. The best part was that it flagged an issue with my 2019 income calculation that could have caused problems. Definitely worth checking out if you're filing a 1045.

After reading this thread, I realized I was having the same issue waiting for my 1045 to process. After 4 months of radio silence, I decided to try contacting the IRS directly using https://claimyr.com and watched their demo at https://youtu.be/_kiP6q8DX5c. Instead of waiting on hold for hours, they got me connected to an IRS agent in about 20 minutes. The agent was actually able to see that my form was stuck in processing due to a simple verification issue. They resolved it on the spot, and my refund was approved within a week after that call. Without that service, I'd probably still be waiting in the dark, not knowing there was an easy fix.

•How does this actually work? Doesn't everyone have to wait on the IRS phone lines regardless? I've tried calling about my business loss carrybacks at least 10 times and never got through.

•Yeah right. There's no way to "skip the line" with the IRS. Sounds like you just got lucky with timing or something. I've been waiting 7 months for my 1045 processing and there's no way to speed it up.

•It works because they have a system that continuously calls the IRS and navigates through the phone tree, then alerts you once they've reached an agent. You don't have to sit on hold - you just get a call back when there's an actual person ready to talk. It saved me hours of frustration. I definitely wasn't just "lucky" - I had already waited over 4 months with zero progress. The IRS agent specifically told me my form needed additional verification and was sitting in a queue. Once they flagged it in their system during our call, it moved forward immediately. It's not about "skipping the line" but actually getting to talk to someone who can look up your specific case.

I have to eat my words about Claimyr from my skeptical comment above. After another month of waiting (now 8 months total for my Form 1045 processing), I broke down and tried the service. Got connected to an IRS agent in about 15 minutes, which was shocking after my previous failed attempts. Turns out my NOL carryback application had been flagged for a missing schedule that I definitely included with my original submission. The agent was able to make a note in the system and actually transferred me to the specific department handling 1045 forms. They found my missing schedule in their system and removed the hold. Just got my refund approved yesterday - would have been waiting indefinitely if I hadn't made that call. For anyone dealing with Form 1045 delays, it's worth trying to get a human on the phone who can actually check your specific situation.

FYI for everyone dealing with Form 1045 - make sure you're aware of the timing limitations. You have to file within 1 year of the end of the tax year in which your NOL occurred. So if your NOL was in 2023, you have until December 31, 2024 to file Form 1045 for the quick refund procedure. If you miss that window, you can still carry back or forward the loss by filing amended returns (Form 1040-X) for each applicable year, but you lose the expedited refund benefit of Form 1045.

•Does this timing requirement also apply to disaster-related losses? I have a business loss from a federally declared disaster area and thought there might be different rules.

•For federally declared disaster losses, you actually have some special provisions available. In these cases, you can elect to claim the loss on the prior year's return, which can get you a refund faster. This is done by filing an amended return (1040-X) for the previous year rather than waiting to claim it on your current year return. The timing requirements can be different for disaster losses, and in some cases, you may have extended deadlines. You should verify the specific disaster provisions that apply to your situation since the IRS often issues special guidance for particular disaster declarations.

Has anyone worked with the IRS Taxpayer Advocate Service when dealing with long Form 1045 processing times? I'm going on 9 months now and wondering if that's an option.

•I used the Taxpayer Advocate Service after waiting 10 months for my 1045 processing. They can help, but only if you can demonstrate a financial hardship due to the delay (like facing eviction, utilities shutoff, can't afford medications, etc). Otherwise, they'll just tell you to keep waiting.

•Thanks for sharing your experience. I'm not in a financial hardship situation yet, but it's getting frustrating having such a large refund in limbo. I might try the Claimyr service mentioned above first to see if I can at least get some information about where my form is in the process.

I filed my Form 1045 in June 2024 for a significant NOL from my consulting business that shut down. After reading this thread, I'm now at about 6 months which seems to align with what everyone else is experiencing. One thing I want to add that hasn't been mentioned - make sure you keep detailed records of everything you submit. I sent mine certified mail and kept copies of every single page. My accountant also recommended attaching a cover letter explaining the situation clearly, which might help the processor understand the case faster. The waiting is brutal, especially when you're counting on that refund, but it sounds like most people are eventually getting their money. I'm going to try calling using one of those services mentioned here if I don't hear anything by month 8.

I'm currently dealing with a Form 1045 situation myself and this thread has been incredibly helpful. Filed mine in August 2024 after a major business loss, so I'm about 5 months in now. Based on what I'm reading here, it sounds like I should expect at least another month or two before seeing any movement. The frustrating part is the complete lack of communication from the IRS - you just have to sit and wait with no updates. One question for those who've been through this: did any of you receive any kind of acknowledgment letter or notice that your Form 1045 was received and being processed? I sent mine certified mail but never got anything back confirming they actually have it in their system. Also curious if anyone tried checking the "Where's My Refund" tool online - does that even work for 1045 applications or is it only for regular tax returns?

•I went through the same thing last year with my Form 1045 - you won't get any acknowledgment letter that they received it, which is really frustrating. The IRS doesn't send confirmation notices for 1045 applications like they do for regular returns. The "Where's My Refund" tool unfortunately doesn't work for Form 1045 either - it's only designed for regular tax return refunds. So you're basically flying blind until they either send your refund or contact you if there's an issue. Since you sent it certified mail, at least you have proof of delivery. That's really important because if it gets lost in their system, you'll need that tracking info. I'd recommend keeping that certified mail receipt handy - you might need it if you have to call them later to track down your application. The radio silence is definitely the worst part of this whole process. Most people I know who filed 1045s didn't hear anything until their refund check showed up or they got a notice asking for additional information.

I'm about 7 months into waiting for my Form 1045 processing after filing in September 2024. Reading through everyone's experiences here is both reassuring and frustrating - at least I know I'm not alone in this endless waiting game. One thing I learned the hard way is to make absolutely sure you include every single supporting document when you file. I initially forgot to include one of my K-1 schedules from a partnership loss, and when I realized the mistake a few weeks later, I had to send an amended 1045 which basically reset my processing clock back to zero. For anyone just starting this process, my advice would be to triple-check everything before mailing it in. Have someone else review your calculations and documentation because any missing piece can add months to an already lengthy process. Also, keep meticulous records of exactly what you sent and when. I created a checklist of every form, schedule, and supporting document, plus took photos of the complete package before sealing the envelope. If you end up having to call the IRS later, you'll need to be able to tell them exactly what was included in your original submission. The wait is excruciating, especially when it's a substantial refund, but based on what I'm seeing here, most people do eventually get their money. Just prepare yourself mentally for 6-8 months minimum.

•This is really helpful advice about the documentation - I'm just starting to prepare my Form 1045 and hadn't thought about creating a detailed checklist like that. The idea of taking photos of everything before mailing is brilliant too. Quick question - when you had to send the amended 1045, did you have to start completely over or were you able to reference your original submission somehow? I'm worried about making a similar mistake and want to understand what happens if you need to correct something after filing. Also, did the IRS ever acknowledge that they received your amended version, or was it the same radio silence as the original filing?
