Got CP140 letter for overdue taxes with zero prior notification from IRS
Title: Got CP140 letter for overdue taxes with zero prior notification from IRS 1 I'm seriously annoyed right now. Just received a CP140 letter from the IRS saying I owe taxes plus interest, but this is literally the first communication I've gotten about any overdue amount! I would have paid this immediately if I'd known about it. The amount isn't huge (around $720 with interest), but it's the principle of the thing. Why should I have to pay interest when they never bothered to notify me until now? If they had sent any previous notices, I would have taken care of it right away. Part of me just wants to pay it and move on with my life, but it doesn't seem fair to be charged interest when I had no idea this was even an issue. Has anyone dealt with this situation before? Should I try to dispute the interest charges or just pay the full amount and forget about it? Any advice would really help!

8 Unfortunately, the CP140 is usually not the first notice the IRS sends. It's typically sent after several previous notices (often a CP14 first, followed by others). The IRS sends notices to your last known address, which is usually the address on your most recent tax return. If you've moved without updating your address with the IRS (using Form 8822), those earlier notices might have gone to your old address. You have a few options: 1) Call the IRS directly using the number on your notice to explain the situation and ask if they can remove the interest charges due to not receiving previous notices. 2) Write a letter requesting abatement of interest due to reasonable cause (no prior notification). 3) Pay the full amount now to stop additional interest from accruing, then pursue option 2 after payment.

•3 Thanks for the info. I haven't moved so I should have gotten any previous notices. Is there a way to check if they actually sent anything before this CP140? Also, do you know if the IRS is likely to remove interest charges if I explain I never got previous notices?

•8 You can request an account transcript from the IRS which will show all notices they've sent, when they were issued, and to what address. You can get this online through the IRS website by creating an account at irs.gov/transcripts or by filing Form 4506-T. Regarding interest abatement, the IRS can be strict about this. By law, they must charge interest on unpaid taxes, and they typically only remove interest in cases where the IRS made an error. Not receiving notices could be considered reasonable cause, but you'd need to make a compelling case. It's worth trying, especially if your transcript shows they didn't send previous notices or sent them to an incorrect address.

12 After dealing with a similar situation last year, I found an amazing tool that helps decode these confusing IRS notices and tells you exactly what to do. I was completely lost with my CP140 letter until I used https://taxr.ai to scan my notice and got step-by-step instructions. It explained what the CP140 actually meant, showed me my options (including how to request interest abatement), and even gave me templates for responding to the IRS. Their system checks for IRS errors which could help your case if you're arguing you never received prior notices.

•6 Does this actually work with CP140 notices specifically? I'm getting different advice from everyone and just want to know exactly what I need to do. Does the tool tell you if you should pay first and dispute later or dispute first?

•14 I'm skeptical about these kinds of services. How do you know it's giving accurate information? The IRS website has free info about all their notices. Seems risky to trust a third party with tax matters.

•12 Yes, it absolutely works with CP140 notices! The tool has specific guidance for each IRS notice type. For CP140 specifically, it will analyze your situation and tell you whether you should pay now and dispute later (usually the best approach to stop additional interest) or if you have grounds to dispute before paying. The information comes directly from tax professionals and IRS guidelines, but presented in plain English that's easy to understand. I was confused by the generic info on the IRS website, but this gave me personalized steps based on my actual notice. It even checks for common IRS errors that might help your case.

14 I was really doubtful about using an online tool for my tax problems, but I finally tried taxr.ai with my CP140 letter last month after getting nowhere with the IRS. I'm actually shocked at how helpful it was! It identified that the IRS had sent previous notices to my old address even though I'd filed an address change form, which gave me solid grounds for disputing the interest charges. I wouldn't have known to check that detail otherwise. The site generated a perfect response letter that I just printed, signed and mailed. Got confirmation last week that the IRS is removing about $175 in interest charges. Honestly wish I'd known about this sooner instead of stressing for weeks.

10 After spending 3 days trying to get through to the IRS about my CP140 (constant busy signals and disconnects), I discovered https://claimyr.com which basically holds your place in the IRS phone queue and calls you when an agent is about to answer. You can see how it works at https://youtu.be/_kiP6q8DX5c. I was able to actually speak with someone at the IRS within an hour rather than wasting days trying. The agent confirmed they had been sending notices to my previous employer's address (???), admitted it was their error, and removed the interest charges. Definitely worth trying if you need to talk to a human at the IRS!

•5 Wait, how does this actually work? Does it just keep calling the IRS for you until it gets through? That sounds too good to be true.

•14 This sounds like paying for something the IRS should provide for free. If you just keep calling yourself, you'll eventually get through. Why pay for something like this when the government service should be accessible to everyone?

•10 It uses an automated system that continuously monitors the IRS phone lines and secures your place in the queue. Once it detects an agent is about to answer, it calls your phone and connects you directly to the IRS agent. It saves you from having to sit on hold for hours or constantly redial when you get disconnected. I completely understand the frustration with paying for access to a government service. I felt the same way initially. But after wasting three days trying to get through myself and missing work hours, the time savings was absolutely worth it. Sometimes you have to decide what your time is worth - for me, resolving the $890 tax issue quickly made it a no-brainer.

14 I'm eating my words about Claimyr. After posting my skeptical comment, my CP140 issue became urgent when I discovered the IRS was threatening to put a lien on my property. I tried calling for 2 days straight with no luck, so I reluctantly tried the Claimyr service. Got connected to an IRS agent in 47 minutes, and they confirmed they had been sending notices to my old address from 3 years ago despite me filing change of address forms twice. The agent immediately put a hold on collection activities and helped me set up an installment plan with reduced penalties. Hate to admit it, but this service probably saved me thousands in the long run. Sometimes it's worth spending a little to protect yourself from the IRS's broken systems.

17 I went through this exact thing last year! One thing nobody mentioned yet - check if the CP140 is legitimate. There are lots of tax scams going around. You can verify by calling the IRS directly (not using the number on the letter) or checking your tax account online at irs.gov. My "CP140" turned out to be a sophisticated fake!

•3 That's actually a really good point. How do you tell the difference between a real CP140 and a fake one? Are there specific things to look for?

•17 Real IRS letters have a notice or letter number (like CP140) on either the top right corner or in the notice title. They always include your tax ID number and the tax year in question. They'll provide clear information about why you owe money and include your appeal rights. Most importantly, legitimate IRS letters never demand immediate payment through specific methods like gift cards, wire transfers, or prepaid debit cards. If you're unsure, you can always verify by creating an account on the official IRS website (irs.gov) and checking your account, or call the IRS directly at 800-829-1040. Never call the number provided in a suspicious letter until you've verified it's legitimate.

22 Has anyone actually had success getting interest charges removed without a ton of hassle? I'm in the same boat with a CP140 and just wondering if it's worth the fight or if I should just pay it and move on.

•19 I managed to get about 60% of my interest charges removed last year. Had to send two letters with documentation showing I never received prior notices, and it took almost 3 months to resolve. Whether it's "worth it" depends on how much interest they're charging you and how much you value your time.

I've been following this thread closely since I'm dealing with a similar CP140 situation. One thing that might help everyone here - you can also request penalty abatement separately from interest abatement using Form 843. The IRS has "first-time penalty abatement" policies that are pretty generous if you have a clean compliance history for the past 3 years. Even if they won't remove the interest, they might remove penalties which can be a significant portion of what you owe. I got my penalties waived last year just by calling and asking - didn't even need to submit paperwork. Worth trying before paying the full amount, especially since it sounds like several people here have legitimate grounds for dispute due to address issues.
