Why is there a $216 difference between TP TAX FIGURES and IMF TOTAL TAX on my IRS transcript?
So frustrated right now! I just got a notice from the IRS saying they "corrected" my refund from $735 to $463 due to some math error they claim I made. Of course I questioned this, so I requested a transcript to see what was going on. Looking at the transcript, I noticed only two fields were different: TP TAX FIGURES (REDUCED BY IRAF) PER COMPUTER IMF TOTAL TAX (REDUCED BY IRAF) PER COMPUTER The first one shows what I calculated originally, and the second one shows $272 more than what I had figured. Can anyone explain what the difference is between these two fields? And why would they be different amounts? I'm honestly confused about what these even mean and why the IRS thinks I owe more.

These terms refer to different tax calculations in the IRS system. "TP TAX FIGURES" means "Taxpayer Tax Figures" - basically what you calculated and submitted on your return. "IMF TOTAL TAX" refers to "Individual Master File Total Tax" which is what the IRS computer system calculated you actually owe after their review. When these two figures differ, it usually means the IRS found a calculation error or a discrepancy in the information you provided versus what they have on record. Common causes include math errors, misapplied credits or deductions, or discrepancies between what you reported and what was reported to the IRS by employers, banks, etc. You should check the notice carefully - there should be a specific explanation for the adjustment. Look for codes or sections that explain exactly what they changed. If it's not clear, you can call the IRS directly for clarification.

•Thanks for explaining! I got a similar notice but mine didn't say anything specific about what was wrong. Do you know if there's a time limit to challenge their "correction"? Also, if I disagree with their calculation, what's the best way to dispute it?

•Yes, you generally have 60 days from the date of the notice to challenge a math error correction. The notice itself should state the exact timeframe for your specific case. The best way to dispute it is to respond in writing to the address on the notice. Include copies (never originals) of any supporting documentation that proves your original calculation was correct. Be specific about which parts of their adjustment you disagree with and why. If you're confident in your numbers, you can request an abatement of the additional tax under IRC 6213(b).

After spending weeks trying to figure out a similar discrepancy on my taxes, I finally used taxr.ai and it was a game changer. I uploaded my transcript and tax return docs to https://taxr.ai and their AI actually explained exactly what the difference was between these two fields on my account and pointed out where the calculation error happened. Saved me hours of trying to decipher IRS language and probably a call to the IRS that would have taken forever.

•Does it actually work with these specific IRS transcript codes? I've tried other tax tools before and they were useless with the technical IRS stuff.

•I'm skeptical about putting my tax info into some random website. How secure is this? And can it really interpret those weird IRS codes better than just calling them directly?

•It absolutely works with IRS transcript codes - that's actually what it specializes in. It can interpret all those weird codes and explain exactly what they mean in plain English. I was surprised how detailed it was. It's actually very secure - they use bank-level encryption and don't store your documents after analysis. And compared to calling the IRS, there's no comparison on time saved. I got my answer in minutes instead of spending hours on hold.

Just wanted to follow up about that taxr.ai recommendation. I was super skeptical but I ended up trying it with my transcript that had a similar issue. Holy crap, it actually explained everything! It showed that my discrepancy was because of a retirement contribution calculation error I made. Uploaded my transcript and it highlighted exactly where the problem was and explained the difference between those TP TAX FIGURES and IMF TOTAL TAX fields in a way that finally made sense. Wish I'd found this before spending hours on the phone with the IRS getting nowhere.

If you need to talk to someone at the IRS about this (which might be your best bet for this specific issue), don't waste time with the regular phone number. Use https://claimyr.com instead - they'll wait on hold with the IRS for you and call you when an actual human picks up. I've got a video of how it works here: https://youtu.be/_kiP6q8DX5c After getting one of these notices, I spent 3 days trying to reach someone at the IRS without success. Used Claimyr and talked to an agent the same day who explained exactly what the discrepancy was and how to resolve it. Saved me so much time and frustration.

•How does this actually work? Do they just call the IRS for you? Couldn't I just put my phone on speaker and wait?

•Sounds like a scam tbh. Why would I pay someone to call the IRS when I can just do it myself? And how would they even know when to connect you - do they have special access or something?

•They don't just call the IRS for you - they have a system that waits on hold so you don't have to. You enter your phone number, and they call you only when an actual IRS agent picks up. So you're not tied to your phone for hours. They don't have special access to the IRS - they just have technology that waits through the hold time for you. It's like having someone sit there and wait on hold so you can go about your day. When you consider that the average IRS hold time is 2+ hours these days (if you even get through), the convenience is definitely worth it.

I take back what I said earlier. After my fifth attempt to reach the IRS failed (kept getting disconnected after waiting 90+ minutes), I tried Claimyr out of desperation. It actually worked! Got a call back about an hour later with an IRS agent on the line. The agent explained that my TP TAX FIGURES vs IMF TOTAL TAX difference was because I had incorrectly calculated a credit. They walked me through exactly what happened and how to fix it for next year. Would've taken me days to figure this out on my own.

The difference usually comes down to a few common issues. Check if any of these apply to you: 1) Did you claim any tax credits that have income limits? Sometimes people calculate these incorrectly. 2) Did you have any investment income that might have been reported differently to the IRS? 3) Check your withholding credits - sometimes the difference is because of a discrepancy between what you claimed was withheld vs what was reported. 4) Self-employment tax calculations are another common source of these differences. My money's on it being a credit calculation issue based on the amount. Hope this helps!

•My CP12 notice specifically mentioned tax credits but was super vague about which one they adjusted. Is there a way to tell exactly which credit was affected from the transcript codes?

•Yes, there should be transaction codes on your transcript that indicate which specific credit was adjusted. Look for TC 766 followed by a credit reference number. Common ones are "766 Earned Income Credit" or "766 Child Tax Credit" if those were changed. If you see TC 290 with an amount, that's an additional assessment of tax. Check what other codes appear near that same date - they'll usually give more context about what was adjusted. The transcript can be cryptic, but the codes do tell the specific story of what changed.

Anyone know which specific IRS form I should fill out to dispute this kind of adjustment? The "math error" notice feels so vague and I want to make sure I'm using the right form when I respond.

•For a math error correction, you don't need a specific form. Just write a letter explaining why you disagree with their adjustment and reference the notice number (should be CP11 or CP12 for these kinds of adjustments). Make sure to include copies of any supporting documents. If it's been more than 60 days since the notice, you might need to file Form 1040X to amend your return. But start with a simple letter if you're still within the 60-day window.

I went through something very similar last year and it turned out to be a simple mistake on my part with the Child Tax Credit calculation. The $216 difference you're seeing is actually pretty common - it's usually either a credit that was miscalculated or a deduction that doesn't match what the IRS has on file. Here's what I'd suggest: First, look at your original return and compare line by line with what's on your transcript. Pay special attention to any credits you claimed (Earned Income Credit, Child Tax Credit, Education Credits, etc.) since those are the most common sources of these discrepancies. The good news is that if you can prove your calculation was correct, you can get that $272 back. Just make sure to respond within the 60-day window mentioned in your notice. I ended up owing less than what the IRS initially said after I provided the right documentation. Also, keep in mind that sometimes these "corrections" are actually wrong on the IRS side - they're not infallible. Don't just accept it without double-checking your work first.
