Confused about the CP24 I received from the IRS - what does it mean?
I filed my taxes using FreeTax USA this year, and I think I messed something up pretty badly. I was expecting around $1,500 back on my Federal refund but ended up only getting $9! Then I got this CP24 letter from the IRS that I honestly don't understand. I've been trying to reach someone at the IRS since I got the notice in early June, but it's literally IMPOSSIBLE to talk to a real person. I've called the number on the letter at least 15 times and just get stuck in an endless phone menu. The letter says I have until August 12th to appeal or respond, but I have no clue what I'm even responding to or how to fix this. I'm totally lost. Should I just redo my taxes? Is it worth paying H&R Block or someone at this point to figure this out? The IRS website help section is completely useless for my situation. Has anyone dealt with a CP24 before or know what it actually means? I'm freaking out a bit since I was counting on that refund money.

The CP24 is a fairly common notice that means the IRS made changes to your tax return that affected your refund amount. Usually, it's because there was a discrepancy between what you reported on your return and what the IRS has on file from your employers, banks, etc. First, carefully read the entire letter - it should explain exactly what changes they made. Common issues include missing income (maybe you forgot a W-2 or 1099), math errors, or claiming credits you weren't eligible for. The letter should have a breakdown of the specific adjustments they made. You don't necessarily need to redo your taxes or pay H&R Block. What you need to do depends on whether you agree or disagree with their changes. If you agree, you don't need to do anything. If you disagree, you need to respond with documentation supporting your original return.

•Thanks for explaining! I think I see the issue now. The letter shows they added some income from a side gig I did that I completely forgot about (it was only like $600). But wouldn't that make my refund even smaller rather than bigger? I'm still confused about where my expected refund went. Also, do I need to file an amended return now or is this letter basically doing that for me?

•Adding unreported income would indeed reduce your refund, not increase it. The CP24 is essentially the IRS amending your return for you, which is why your refund was less than expected. The $600 of additional income likely resulted in more taxes owed, reducing your original expected refund. You don't need to file an amended return if you agree with their assessment. The CP24 notice has already made the adjustment. However, if you believe they're incorrect, you should gather documentation proving your case and respond before the deadline.

After dealing with a similar CP24 situation last year, I discovered this service called taxr.ai (https://taxr.ai) that saved me so much time and confusion. I uploaded a picture of my CP24 notice to them, and they explained exactly what happened with my taxes in regular English - not IRS jargon. They showed me that the IRS had actually found a reporting error from one of my investment accounts that I hadn't caught. The explanation highlighted which line items were affected and even gave me options for how to respond. Way better than trying to decipher it myself.

•Does it work for other IRS notices too? I got something called a CP2000 last month and I'm totally confused.

•I'm kinda skeptical - how much does it cost? These tax help services usually end up being more expensive than just paying a pro to handle it for you from the start.

•Yes, it works for pretty much all IRS notices including CP2000s. It's especially helpful for those because CP2000s can be really complex with lots of different issues to address. The service is actually very affordable compared to paying a tax professional for a consultation. Plus, you get the analysis almost immediately rather than waiting for an appointment. They focus on explaining what the notice means and what your options are - which is exactly what most people need when these letters arrive.

I was super skeptical about taxr.ai when I first saw it mentioned here, but I was desperate after getting a similar notice. Uploaded a pic of my CP24 and got a detailed breakdown within minutes explaining that I had claimed a tax credit incorrectly. They highlighted exactly which lines on my return were problematic and gave me step-by-step instructions on how to respond. Ended up saving almost $800 of my refund by properly documenting my eligibility! The explanation made it clear what documentation I needed to send back to the IRS. Wish I'd known about this sooner instead of panicking for days.

After trying literally EVERYTHING to contact the IRS about my CP24 notice last tax season (calling daily for weeks, no joke), I finally found Claimyr (https://claimyr.com). They have this system that basically holds your place in the IRS phone queue and calls you when an actual human agent is about to answer. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was super dubious at first, but they got me connected to a real IRS person in about 45 minutes when I had been trying on my own for DAYS. The agent was able to explain my CP24 in detail and even helped me set up a payment plan since I had to pay some back taxes.

•Wait how does this actually work? Do they have some special connection to the IRS or something? I've been trying that stupid phone menu for weeks now.

•This sounds like total BS. If it was possible to "skip the line" with the IRS everyone would do it. The IRS phone system is deliberately designed to be impossible to navigate. I'll believe it when I see it.

•They don't have any special connection to the IRS - they use technology that navigates the phone system and stays on hold for you. It basically automates the process of calling, going through all the menu options correctly, and waiting on hold. When a human finally answers, their system conference calls you in. It's not about skipping the line - you still wait your turn, but their system does the waiting instead of you having to sit there with your phone for hours. It saved me from having to redial constantly or waste an entire day on hold. I was skeptical too, but it absolutely works.

I can't believe I'm saying this, but I tried Claimyr after posting that skeptical comment above. I was desperate after my third week of trying to reach the IRS about my notice. IT ACTUALLY WORKED. Got a call back in about an hour with an IRS agent on the line. The agent explained that my CP24 was issued because they found unreported interest income from a bank account I forgot about (only $85, but still triggered a review). They walked me through exactly what I needed to do to appeal since I had documentation showing I did include that income. Currently waiting on the results of my appeal, but at least I got it submitted before the deadline!

Before you pay H&R Block, try calling the Taxpayer Advocate Service at 1-877-777-4778. They're an independent organization within the IRS that helps people who are experiencing financial hardship or who haven't been able to resolve their tax issues through normal IRS channels. They might be able to help you understand the CP24 and figure out next steps.

•I actually tried calling them after my fifth failed attempt with the regular IRS number. They have a message saying they're not taking new cases unless you're facing "immediate financial hardship" which apparently means like imminent eviction or utility shutoff. Since I'm just confused about my refund, they wouldn't help me. The whole system feels designed to be impossible to navigate.

•That's unfortunate but not surprising these days. The TAS has been overwhelmed for years now. If the direct IRS route isn't working, another option is to check if you qualify for free help from a Low Income Taxpayer Clinic (LITC) or the Volunteer Income Tax Assistance (VITA) program. They can often help explain notices and what steps to take. If you made under $73,000 last year, you might qualify for their assistance. You can find locations on the IRS website under "Free Tax Return Preparation.

Just FYI - if you're using FreeTaxUSA or other self-prep software and get confused by notices like CP24, sometimes calling the software's customer support can help. I got a similar notice last year and FreeTaxUSA's support team actually explained what it meant and how to respond. Might be worth trying before paying for professional help.

•This is great advice! I worked in tax software support and most people don't realize we can help with post-filing issues. We can't represent you with the IRS, but we can definitely explain notices and help you understand what might have happened with your return.

I went through almost the exact same situation last year! Got a CP24 that slashed my expected refund and spent weeks trying to reach the IRS. Here's what I learned: First, don't panic about the August 12th deadline - that's plenty of time to figure this out. The CP24 should have a detailed explanation section that breaks down exactly what they changed. Look for a section that shows "Original Amount" vs "Corrected Amount" for different line items. In my case, they had found a 1099-INT from a savings account that I completely forgot about (only $23 in interest, but still). The extra income meant I owed a bit more in taxes, which came out of my refund. A few practical tips: - Check if you have all your tax documents. Log into your bank accounts, investment accounts, etc. and see if there are any 1099s or other forms you might have missed - The IRS usually gets copies of these forms directly from employers/banks, so they know about income even if you forgot to report it - If you agree with their changes, you don't need to do anything - just accept the smaller refund - If you disagree, you need to send documentation proving your case before the deadline Don't rush to pay H&R Block yet - try calling FreeTaxUSA support first as someone mentioned. They might be able to help you understand what happened for free.

•This is really helpful advice! I'm dealing with a similar CP24 situation right now and was getting overwhelmed by all the conflicting information online. Your point about checking all bank and investment accounts for missing 1099s is spot on - I just realized I might have missed a small 1099-DIV from an old investment account I barely use. One quick question - when you say "send documentation proving your case," what exactly does that look like? Do you just mail copies of the forms they say you're missing, or is there a specific format the IRS wants? I'm worried about messing up the response and making things worse.

•@Omar Hassan Great question! When responding to a CP24, you typically need to send a written response along with supporting documents. Here s'the format that worked for me: 1. Write a brief letter stating whether you agree or disagree with their changes 2. If you disagree, explain why and reference the specific line items 3. Include copies not (originals of) any supporting documents like missing 1099s, receipts, or other tax forms 4. Make sure to include your SSN and the tax year on every page 5. Send it to the address specified in the CP24 notice usually (different from where you normally file In) my case, I actually agreed with their changes once I found the missing 1099-INT, so I just sent a brief letter saying I "agree with the adjustments made along" with a copy of the form I had missed. Keep copies of everything you send for your records! The key is responding before the deadline - even if you re'not 100% sure, it s'better to respond with what information you have than to miss the deadline entirely.

I had a CP24 last year that initially terrified me, but it turned out to be much simpler than I thought. The key thing to remember is that CP24 notices are actually pretty routine - the IRS processes millions of them every year when they find small discrepancies between what you reported and what they have on file. Here's my step-by-step approach that worked: 1. **Read the notice carefully** - There should be a section showing "per your return" vs "per our records" that breaks down exactly what changed 2. **Gather all your tax documents** - Go through bank statements, employer records, investment accounts, even that random side gig you mentioned 3. **Compare what you filed vs what they found** - In your case, sounds like they caught unreported income that reduced your refund The $1,500 to $9 drop suggests they found significant unreported income or you claimed a credit you weren't eligible for. Don't panic about the August deadline - that's actually a generous amount of time. Before paying for professional help, try calling FreeTaxUSA's support line. Most tax software companies will help explain notices for customers, and it's free. If you do need to respond to the IRS, keep it simple - either agree with their changes or provide documentation showing why they're wrong. The silver lining? Once this gets resolved, you'll be much better at catching these issues in future tax seasons!

•This is such great advice, especially about not panicking! I'm in a similar boat with my first CP24 and was convinced I'd done something terribly wrong. Your point about these being routine really helps put things in perspective. One thing I'm curious about - you mentioned that the $1,500 to $9 drop could be from claiming a credit you weren't eligible for. @Taylor Chen, did you claim any credits like the Earned Income Credit or education credits? Sometimes those get reversed if the IRS thinks you don't qualify, which can cause a huge swing in your refund amount. Also, totally agree about calling FreeTaxUSA first. I used TurboTax last year and their support was actually really helpful when I got confused about a notice. Way cheaper than going straight to a tax pro!

I've been through this exact situation! Got a CP24 that dropped my refund from $2,200 to about $150 - turns out I had completely forgotten about a 1099-MISC from some freelance work I did in January. Here's what I wish someone had told me when I was panicking: The CP24 is actually the IRS doing you a favor by catching the mistake before you get in bigger trouble later. They automatically adjusted your return and sent you whatever refund you were actually entitled to. The most important thing right now is to locate that CP24 letter and find the section that shows the line-by-line changes they made. It should clearly show what income they added or what credits they removed. Once you see exactly what they changed, you can decide if you agree or disagree. Since you mentioned a side gig, that's probably exactly what happened - the company that paid you sent a 1099 to the IRS, but you forgot to include it on your return. The added income means more taxes owed, which comes directly out of your refund. Don't stress about the August deadline - you have plenty of time. And honestly, if their changes are correct (which they usually are), you don't need to do anything at all. The adjustment is already final and you got the correct refund amount. Save yourself the H&R Block fee unless you find something genuinely wrong with their calculations!

•This is exactly what I needed to hear! I've been spiraling about this CP24 for days thinking I was going to owe thousands or get audited. Your explanation about it being the IRS "doing me a favor" really reframes the whole situation. I just went back and re-read my letter more carefully, and you're absolutely right - there's a section that shows they added $847 in income from what looks like a 1099-NEC. I completely spaced on reporting some app-based delivery work I did early in the tax year. The math actually makes sense now - that extra income bumped me into owing more taxes, which is why my refund got slashed. I'm honestly relieved it's something this straightforward rather than some complex audit situation. Thanks for the reality check about not needing H&R Block! I was about to drop $300+ on something I probably don't even need to respond to.

I've been helping people with CP24 notices for years, and I want to add a few important points that might help clarify things: First, that drop from $1,500 to $9 is actually pretty typical when unreported income is involved. The IRS likely found income that pushed you into a higher tax bracket or made you ineligible for certain refundable credits you claimed. Here's what you should do RIGHT NOW: 1. Look at the detailed breakdown in your CP24 - it will show exactly which line items changed 2. Check if they added income OR removed credits (both can cause massive refund reductions) 3. Gather all your 2023 tax documents, especially any 1099s from that side gig you mentioned The good news is that CP24s are usually straightforward corrections, not the start of an audit. The IRS gets copies of all the 1099s and W-2s issued in your name, so they can spot missing income pretty easily. If their changes are correct (which they usually are), you don't need to respond at all - just accept the corrected refund amount. If you disagree, you'll need to provide documentation proving your original return was accurate. Don't rush to pay a tax pro yet. Start by calling FreeTaxUSA's customer support - they can often explain exactly what happened with your return for free since you're their customer.
