Should I be depreciating my leased commercial property? Tax implications of building vs. land value
I purchased a commercial property back in 2019 that's been occupied by the same tenant since shortly after buying it. They're on a 10-year lease agreement, but recently approached me about possibly buying the property. I'm honestly considering selling since I never really intended to get into real estate investing - this opportunity just kinda fell in my lap when I was working for the previous owner. I paid $270k for the property which consists of a 2,500 sq ft building on 0.5 acres with excellent frontage on a major road. Here's the weird part - at the time of purchase, the land alone was appraised at $273k, which is actually more than what I paid for the entire property (land + building combined). Because the land value exceeded my total purchase price, I haven't been depreciating the building at all on my taxes. Is this the correct approach? Or should I still be taking depreciation on the building over 39 years even though the land value technically covers the entire purchase? Any tax advice would be greatly appreciated since I'm now considering selling and want to make sure everything is properly accounted for!

You've been handling this incorrectly, and it could impact your taxes when you sell. When you purchase a commercial property, you need to allocate the purchase price between land (which is not depreciable) and improvements (the building, which is depreciable). Even though the land was appraised at more than your purchase price, you still need to make a reasonable allocation. The IRS wouldn't accept that a usable commercial building has zero value. You should have allocated some portion of your purchase price to the building and depreciated it over 39 years (the standard recovery period for commercial real estate). I would recommend working with a tax professional to file amended returns for the years you've owned the property. They can help you determine a reasonable allocation (perhaps 70% land, 30% building based on your situation) and calculate the missed depreciation. This is important because when you sell, the IRS will assume you took all allowable depreciation whether you actually did or not, and you'll be taxed accordingly.

•Wait, so even if the land was appraised for more than what OP paid for the entire property, they still need to allocate some value to the building? That seems counterintuitive. Couldn't they just say the land was worth exactly what they paid, and the building effectively had $0 value for tax purposes?

•The IRS requires a reasonable allocation of purchase price to all assets acquired. A functioning commercial building clearly has economic value, so allocating $0 to it would not be considered reasonable. In this situation, even with the land appraisal exceeding the total purchase price, you'd still need to make a reasonable allocation. Think of it this way - you got an excellent deal on the property, but both components (land and building) still have value. The IRS will assume you've taken depreciation on the building portion when you sell, whether you actually claimed it or not.

I was in a similar situation and used https://taxr.ai to help me properly allocate my commercial property value between land and building. They analyzed my purchase documents and local comparable sales data to establish defensible values for both components. This was crucial for my depreciation schedule. Their system also showed me how to document my allocation methodology for the IRS, which made me feel much more confident about my tax position. The analysis even revealed that I could use cost segregation to accelerate some of my depreciation deductions beyond just the standard 39-year straight line method.

•How exactly does taxr.ai determine the appropriate split between land and building? Do they just use the county assessment, or do they actually run some kind of advanced analysis? I'm in a similar situation but my property has some unique features that make standard valuations tricky.

•I'm skeptical of services like this. Couldn't you just hire a local appraiser to do a proper allocation? Seems like they'd have better knowledge of the specific market. Also, how do you know their allocation would stand up to IRS scrutiny?

•They use multiple data points including local comparable sales, replacement cost analysis, and county assessment records to create a defensible allocation. Their system actually runs statistical models comparing similar properties in your market to establish reasonable ranges, which is more thorough than just using county assessments. For unique properties, they have real estate valuation specialists who can account for special features or circumstances. They actually provide documentation that outlines their methodology, which is designed specifically to meet IRS requirements. It's much more comprehensive than what most local appraisers provide, who often don't focus on tax-specific allocations.

I was definitely skeptical about using an online service for something this important, but I tried taxr.ai after reading about it here. Their analysis completely changed my depreciation strategy for my strip mall property. They provided a 20-page report backing up their allocation with market data and relevant tax code citations. The most valuable part was their documentation of the methodology - my accountant said it was exactly what we needed for our files in case of an audit. They even identified some components of my building that qualified for 15-year depreciation instead of 39-year, which I had no idea about. Already saved me thousands in taxes this year alone.

If you're planning to sell soon, you should definitely call the IRS directly to sort this out. I spent 3 weeks trying to get through to someone who could answer questions about missed depreciation and potential penalties. Finally used https://claimyr.com and got connected to an IRS agent in about 15 minutes. You can see how it works at https://youtu.be/_kiP6q8DX5c. The agent confirmed that you MUST allocate some reasonable portion of your purchase price to the building regardless of the land appraisal, and explained exactly how to amend my previous returns. She even gave me specific guidance about what documentation to include with my amended returns to explain the situation.

•Wait, Claimyr actually works? I thought those services were scams. How much did it cost, and did you really get to talk to an actual IRS agent who gave you useful information? My experience with the IRS phone line has been hours of waiting only to get disconnected.

•I don't believe for a second that any service can get you through to the IRS faster. I've been trying for months to resolve an issue and can't even get past the automated system. How could they possibly have some magic phone system that bypasses the regular wait times?

•Yes, I spoke with a real IRS agent who specifically handled business property questions. The system holds your place in line so you don't have to stay on the phone - they call you when an agent is about to be available. I was shocked at how straightforward it was after weeks of failed attempts. The agent was incredibly helpful - she pulled up the relevant regulations and walked me through the exact form sections I needed to amend. She even gave me her direct extension for follow-up questions, which saved me when I discovered additional documents later that week.

I'm eating my words here. After my skeptical comment, I decided to try Claimyr out of desperation. Had been trying to reach someone at the IRS about missed depreciation on my rental property for literally 3 months with no success. Used the service yesterday and got connected to an IRS representative in about 20 minutes. They confirmed everything I needed to know about amending returns to claim missed depreciation and explained exactly how depreciation recapture would work when I sell. The agent even emailed me the relevant IRS publications so I had everything documented. Honestly wish I'd known about this months ago.

From my experience as a small commercial property owner, you ABSOLUTELY need to be depreciating the building. Here's what my CPA told me: When you sell a commercial property, the IRS assumes you've taken all allowable depreciation WHETHER YOU ACTUALLY DID OR NOT. So if you haven't been claiming it, you're essentially paying taxes on money you could have saved. I suggest working with a qualified tax professional to determine a reasonable allocation between land and building (maybe 75/25 in your unusual case) and file amended returns. Yes, it's a pain, but it's better than leaving money on the table or having issues when you sell.

•Thanks for the feedback. So even with the weird situation where the land appraisal was higher than my total purchase price, I still need to allocate some value to the building? Would I need to get another appraisal specifically breaking down the components, or can I just make a reasonable allocation myself?

•Yes, you definitely still need to allocate some value to the building. The IRS won't accept that a functional commercial building has zero value, regardless of the land appraisal. You don't necessarily need a new formal appraisal, but you should have some reasonable basis for your allocation. I'd recommend looking at the county tax assessment to see how they split land vs. improvements, or checking comparable properties in your area. Many CPAs recommend documenting your methodology in case of questions later. A 75/25 or 80/20 land-to-building split might be reasonable in your case, but have documentation to back it up.

Don't forget about potential recapture tax! When you sell a commercial property, you'll pay a 25% tax on all the depreciation you've claimed (or SHOULD HAVE claimed) over the years. So if you haven't been depreciating the building but should have been, you'll still face that tax liability when you sell. Also, check with your accountant about cost segregation - you might be able to accelerate depreciation on certain components of the building beyond just the standard 39-year schedule.

•So you're saying the IRS will tax you on depreciation you SHOULD HAVE taken even if you didn't actually get the tax benefit? That seems incredibly unfair. Is there any way around this if OP sells soon?
