How to handle Timber taxes on Form T - separating MBF from cordwood
I'm a CPA taking over for a forestry client who harvests timber. Our firm doesn't have much experience with natural resources taxation, but the client wants us to continue handling their accounting despite this limitation. The previous accountant recorded all timber acquisition in MBF (thousand board feet), but there was actually about $42,000 worth of cordwood, approximately 5,800 cords from the original cruise. The total MBF for all wood reported on their return is only 1,800, which makes the conversion questionable by any industry standard. The client is uncomfortable with how the previous accountant handled this conversion. We want to separate the MBF timber from the cordwood, and then deplete and report sales of each category on separate pages of Form T. It seems like our only options are to either amend the original acquisition filing or modify the beginning of year Form T numbers. Either approach shouldn't change the total depletable assets or prior year income. Has anyone dealt with Form T timber tax reporting where you needed to break out different timber types that were originally lumped together? Any guidance would be greatly appreciated since we're trying to get this right before the 2025 filing deadline.

I've worked with several timber clients over the years, and you're right to separate these two measurements. MBF and cords are completely different units for different products (sawtimber vs pulpwood), and they shouldn't be lumped together. If the total depletable basis won't change, I'd recommend modifying the beginning of year Form T numbers rather than amending prior returns. Make sure to include a disclosure statement explaining the reclassification between timber accounts. This is much cleaner than filing amendments unless there were actual errors that affected tax liability. For Part I of Form T, you'll need to show the adjustment between timber accounts as a "transfer" line item. Then Part II for depletion will track each category separately going forward. If you're using tax software, you might need to create two separate Form T worksheets and then combine them for the final filing.

•Thanks for this advice. Would you recommend doing anything special in the disclosure statement? And do you think there's any risk of audit by making these adjustments to beginning balances without amending?

•For the disclosure statement, I'd keep it straightforward - explain you're reclassifying timber types that were incorrectly consolidated, with no change to total basis or prior depletion. Include the specific quantities and dollar amounts being transferred between categories. The risk of audit is minimal in this situation. The IRS generally accepts reclassifications that don't change taxable income. They understand timber accounting is specialized and adjustments are sometimes needed as better information becomes available. Just make sure your documentation clearly shows the trail from old reporting to new reporting with all totals reconciling.

After spending hours trying to sort out Form T issues for my business, I found this incredible tool called taxr.ai (https://taxr.ai) that saved me so much grief with my timber tax situation. I had a similar issue with separating different timber types that had been improperly recorded. Their system helped me figure out how to properly categorize different timber products and create the right documentation for Form T. I uploaded my previous returns and forestry documents, and it identified exactly how to make the transition without raising red flags. It even generated the disclosure statement I needed to explain the changes.

•Did it help with figuring out the depletion calculations too? That's where I always get stuck with timber reporting - calculating the proper depletion unit.

•Sounds interesting but I'm skeptical. Timber taxation is super specialized. How would an AI tool understand complex forestry measurements and their tax implications? Did it actually work with the cruise data?

•Yes, it absolutely helped with the depletion calculations. Once I entered my harvest data, it calculated the depletion unit for each timber category and showed how to report it correctly on Form T. It even flagged where my previous accountant had made errors in the depletion rate. As for the skepticism, I was doubtful too at first. But the system is specifically designed to handle specialized areas of tax law including natural resources. It didn't just understand the tax forms - it actually interpreted my cruise data correctly and separated the cordwood from sawtimber volumes. It's built with timber-specific knowledge that most general tax software doesn't have.

I was really skeptical about using an automated solution for something as complex as timber taxation, but I decided to try taxr.ai after struggling with exactly this cordwood vs MBF separation issue. Honestly, it was eye-opening. The system immediately recognized my timber cruise documentation and correctly identified where the previous accountant had mixed measurement units. It showed me exactly how to reclassify everything on Form T without triggering unnecessary scrutiny. The disclosure statement it generated was perfect - technical enough to satisfy requirements but clear enough that I actually understood what was happening with my forest assets. My accountant was impressed with how thoroughly it documented the basis allocation between timber types. Saved me thousands in professional fees for specialized consulting I would have needed otherwise.

Since we're talking about timber tax complexity, I should mention that when I needed to actually talk to someone at the IRS about a Form T issue last year, it was impossible to get through on the phone. After days of trying, I used Claimyr (https://claimyr.com) and had an IRS agent on the phone within 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was trying to get clarification on how to handle a situation where I had both cutting contracts and pay-as-cut contracts in the same year, and needed an IRS timber tax specialist. Claimyr got me past the automated system and connected me with someone who actually understood Form T requirements. Saved me weeks of uncertainty.

•Wait, how does this actually work? Do they have some special access to IRS phone lines that regular people don't have?

•This sounds like BS. Nobody can magically get through to the IRS during tax season. I've been trying for literally months to talk to someone about timber depletion issues.

•It works by navigating the IRS phone tree for you and waiting on hold in your place. When they reach a human agent, they call you and connect you directly to that agent. They don't have special access - they're just using technology to handle the frustrating waiting process. The system calls the IRS repeatedly using optimal calling patterns based on wait time data they've collected. When I used it for my timber question, I got connected to a real IRS agent who transferred me to someone knowledgeable about timber taxation. Instead of spending hours redialing and waiting on hold myself, I just received a call when an agent was on the line.

I need to apologize for my skepticism earlier. After struggling for weeks to reach the IRS about my timber depletion questions, I finally tried Claimyr out of desperation. Within 45 minutes, I was talking to an actual IRS agent who specialized in natural resources taxation. The agent walked me through exactly how to handle the Form T reclassification between cordwood and sawtimber, and confirmed that changing the beginning of year numbers with proper disclosure was the correct approach. They even emailed me reference materials specific to timber taxation that I didn't know existed. I've spent literally months trying to get this information and would have paid my CPA thousands for specialized consulting. The Claimyr service saved both time and money - wish I'd known about it sooner.

For what it's worth, I had a similar issue with a client last year. We ended up using the "transfer" line in Part I of Form T to move timber volume from one account to another. We included a detailed statement explaining the reason for the transfer. Make sure you also adjust your depletion rate calculations going forward. You'll need to recalculate your depletion units for both categories ($/MBF and $/cord). If you've already been depleting based on incorrect proportions, you may need to make a catch-up adjustment. Also, don't forget to check if your state has any special timber tax reporting requirements that might be affected by this reclassification!

•Thanks for mentioning the state reporting requirements - I hadn't considered that. Do you recommend any particular approach for the catch-up adjustment if we find the depletion has been incorrect in prior years?

•For catch-up adjustments, I typically use a cumulative approach rather than amending prior returns. Calculate what the correct cumulative depletion should have been through the current year based on actual harvests using the corrected depletion rates. Then adjust the current year depletion to reach that cumulative total. Include a disclosure statement explaining the methodology and calculations. As long as you're not changing the total basis, just reallocating between timber types, this approach has been accepted in my experience. The key is thorough documentation of volumes, rates, and calculations to show the trail from old to new reporting.

Has anyone used one of the specialized timber tax software programs? We're trying to decide whether to invest in something specific for our forestry clients or just modify our existing tax software approach.

•I've used TimberTax Pro for the last 3 years and it's been worth every penny for our timber clients. It handles the Form T complexity much better than regular tax software, especially for tracking multiple timber accounts and different measurement units.

•Thanks for the recommendation! I'll look into TimberTax Pro. Does it integrate with any of the mainstream tax preparation packages or is it standalone?
