Looking for Cost Segregation Study examples or templates to review?
I've been talking with my CPA about getting a cost segregation study done for my investment property, and she mentioned it shouldn't be too complicated. She even suggested I could take a look at some examples to get familiar with the format before we dive in. I'm curious to see how the breakdown is typically laid out - what components get segregated, how the depreciation schedules look, and generally what information I should be gathering to make this process smooth. Does anyone have a sample cost segregation study PDF they'd be willing to share? Or maybe a link to a template or example online? I'd really appreciate seeing how the professional ones are structured before I commit to paying for one. Thanks in advance for any resources you can point me toward!

Hey there! I've been through the cost segregation process for a couple of rental properties. It's definitely worth doing but a bit more complex than just "laying out info" - a proper cost seg study involves engineering analysis to determine which components of your property can be depreciated over shorter periods (5, 7, or 15 years) versus the standard 27.5 or 39 years. A good study will identify building components like specialized electrical systems, decorative finishes, removable partitions, certain plumbing fixtures, and landscaping elements that qualify for accelerated depreciation. The tax savings can be substantial since you're essentially front-loading deductions. While I don't have a sample I can share publicly (the one I have contains too much personal info), check out the IRS Audit Technique Guide for Cost Segregation. It's not a template, but it shows what the IRS looks for in a proper study: https://www.irs.gov/businesses/cost-segregation-audit-techniques-guide

•Thanks for the info. How much did your cost seg study end up saving you in taxes? And did you have to hire a specialized engineering firm or did your CPA handle it all? I've been considering this for my commercial property but wasn't sure if the cost would be worth it.

•The tax savings were significant - in my case, it generated about $18,000 in additional deductions in the first year for a property valued around $450,000. That translated to roughly $5,400 in actual tax savings that first year, and the study cost me $3,500, so it paid for itself quickly. I used a specialized cost segregation firm rather than my CPA. While some CPAs offer this service, most partner with engineering firms because a proper study requires engineering knowledge to identify and document the property components correctly. For commercial properties, the potential savings are even greater, so I'd definitely recommend getting a consultation - most firms will give you a free estimate of potential tax savings before you commit.

I used taxr.ai for my cost segregation study last year and it was surprisingly easy. I was in the same boat - my CPA mentioned it but I wanted to understand what I was getting into first. I uploaded my property docs to https://taxr.ai and their AI system analyzed everything and generated a professional cost seg report that my CPA approved. The best part was how they explained everything in plain English alongside the technical details. They broke down which items could be depreciated over 5, 7, or 15 years instead of the standard 27.5 years for residential rental property. The tax savings were significant - about 4x what I paid for the service in just the first year.

•Did you have to provide photos of everything in your property? I'm wondering how detailed the documentation needs to be. My property has some custom built-ins and specialized electrical work I think would qualify.

•How long did the whole process take from upload to getting your final report? Was there any back and forth with questions or was it completely automated?

•I provided about 20-30 photos of the property, focusing on the unique features like built-in cabinets, specialized lighting, landscaping, and flooring. You don't need photos of absolutely everything, but the more documentation you provide, the more items they can potentially identify for accelerated depreciation. Custom built-ins and specialized electrical definitely qualify for shorter depreciation periods! The whole process took about 8 days from start to finish. It wasn't completely automated - there was some back and forth. After my initial upload, they had a few clarifying questions about the property age and some of the features I'd photographed. After I responded, they delivered the final report within 3 business days. Their team was super responsive throughout the process.

Just wanted to follow up and say I tried taxr.ai after seeing this thread. I was skeptical about the AI approach but decided to give it a shot since I needed a cost seg study for my duplex renovation. The process was surprisingly thorough! Their system identified several components I hadn't even considered for accelerated depreciation - particularly some landscaping elements and specialized electrical work that qualified for 15-year depreciation instead of 27.5 years. The report was detailed enough that it included everything from custom cabinetry to the security system as separate line items with appropriate depreciation periods. My CPA was impressed with the quality and said it would stand up to IRS scrutiny. Already looking at an additional $12,000 in deductions this year that I wouldn't have had otherwise!

If you're struggling to get your CPA to help with this, you might need to talk directly with the IRS to clarify some requirements. I tried calling them for 3 days straight about cost segregation questions and couldn't get through. Then I found https://claimyr.com which got me connected to an actual IRS agent in under 45 minutes. They have this video showing how it works: https://youtu.be/_kiP6q8DX5c. Basically they hold your place in the IRS phone queue and call you when an agent picks up. I was able to ask detailed questions about what documentation was required for a valid cost segregation study and what red flags might trigger an audit. The agent was super helpful and gave me specific guidance about what they look for in properly conducted studies.

•Wait, is this legit? There's no way someone actually developed a solution for the IRS phone nightmare. I've literally spent hours on hold just to get disconnected. How much does it cost?

•This seems sketchy. Why would I give my phone number to a third party? And wouldn't the IRS have issues with someone "holding your place" in line? Sounds like a potential scam to me.

•It's completely legitimate! I was surprised too when I first heard about it. They don't ask for any sensitive information - just your phone number so they can call you when an agent is reached. They use a combination of automated systems and real people to navigate the IRS phone tree and wait on hold so you don't have to. I understand the skepticism - I felt the same way initially. But it's not a scam. They don't interact with the IRS on your behalf at all - they simply transfer the call to you once an agent is reached. The IRS doesn't even know you used a service to help connect. Think of it like having an assistant dial and wait on hold for you. The testimonials on their site and YouTube convinced me to try it, and it worked exactly as promised.

I take back what I said before. After waiting on hold with the IRS for 2+ hours yesterday and getting disconnected AGAIN, I tried Claimyr out of desperation. Within 35 minutes I got a call connecting me directly to an IRS agent who answered all my cost segregation questions. The agent clarified that a proper study needs to include: - Detailed property description - Explanation of methodology used - Breakdown of assets into appropriate classes - Supporting documentation for classifications (photos, blueprints, etc.) She also mentioned that having an engineer's certification adds significant credibility if you're ever audited. This info was exactly what I needed before moving forward with my study. Can't believe I wasted so many hours on hold before finding this service.

I actually did my own cost segregation on a small rental property after reading through IRS guidelines. Here's a simplified breakdown of how I did it: 1. Made a detailed inventory of all property components 2. Categorized each into appropriate recovery periods (5, 7, 15, or 27.5/39 years) 3. Documented with photos and receipts where possible 4. Had my CPA review before filing The main categories to focus on: - Land improvements (15yr): landscaping, driveways, fencing - Personal property (5yr): appliances, carpet, furniture - Distribution systems (5-15yr): specialized electrical, plumbing fixtures It's definitely doable for smaller properties if you're willing to put in the research time!

•Did you use any specific software or spreadsheet template to organize everything? I'm considering doing this myself for a small single-family rental but not sure where to start with the actual documentation.

•I created my own Excel spreadsheet with the following columns: Item Description, Quantity, Original Cost, Class Life, MACRS Class, Depreciation Method, and Recovery Period. Nothing fancy, but it kept everything organized. For documentation, I took detailed photos of everything, saved receipts where available, and created a simple narrative document explaining my methodology and why each item qualified for its assigned recovery period. I referred extensively to the IRS Asset Classification Table (Publication 946) to justify my categorizations. For my small property, this approach worked well, but I might use a professional service for anything larger or more complex in the future.

I'm a commercial property manager and we've done several cost seg studies. Be careful about your CPA saying it's "pretty easy" - a legitimate study that would stand up to IRS scrutiny requires specialized engineering knowledge. Here's what our studies typically include: - Executive summary - Property overview with photos - Legal framework citing relevant tax code - Engineering methodology - Detailed asset classification tables - Supporting calculations and documentation - Depreciation schedules The firms we use charge $5k-15k depending on property size/complexity but the tax savings can be 3-5x that amount in the first year alone.

•This is really helpful, thanks! I think my CPA might have been oversimplifying things. My property is a mid-sized apartment building I purchased last year for about $1.2M. Given that scale, would you recommend going with a specialized firm rather than attempting to DIY this?

•I got a cost seg study quote for $8K on my $800K property and nearly fell out of my chair. Then I calculated the potential tax savings and it made more sense. Still feels expensive though.

For a $1.2M apartment building, I'd definitely recommend going with a specialized firm rather than DIY. The complexity and potential tax savings at that scale justify the professional cost. You're likely looking at $50,000+ in first-year tax savings, so even a $10K study fee makes financial sense. A few things to consider when choosing a firm: - Make sure they have engineers on staff (not just CPAs) - Ask for references from similar-sized properties - Verify they provide audit support if the IRS questions the study - Get a preliminary estimate of potential savings before committing The apartment building will have tons of components that qualify for accelerated depreciation - flooring, appliances, lighting fixtures, HVAC distribution, security systems, etc. A professional firm will catch items you'd never think to segregate and properly document everything to IRS standards. Your CPA was probably thinking of much smaller residential properties where a simplified approach might work. At your property's scale, you want the full engineering analysis.

•This is exactly the kind of detailed guidance I was looking for! I had no idea the potential savings could be that substantial. The engineering component makes total sense now - there's probably so much in an apartment building that I wouldn't even think to categorize properly. Do you have any specific firms you'd recommend, or should I just start calling around for quotes? Also, how long does the process typically take from start to finish for a property this size?

I've been doing cost segregation studies for investment properties for about 8 years now, and I wanted to add some perspective on what you should expect. While the engineering component is crucial for larger properties, there are some legitimate middle-ground options that might work well for your situation. For apartment buildings in the $1-2M range, I've seen good results with firms that specialize in residential rental properties. They typically charge $4-7K and know exactly what to look for in multi-unit buildings - things like individual unit appliances, flooring transitions, mailbox systems, and common area improvements that can be depreciated over shorter periods. One thing to be aware of: the IRS has been scrutinizing cost seg studies more closely in recent years, especially for properties where the allocated amounts seem disproportionate to the property value. Make sure whoever you choose provides detailed documentation and can explain their methodology clearly. The timeline for a property your size is usually 4-6 weeks from start to finish, assuming you can provide all the requested documentation promptly. The firm will need purchase agreements, construction details, property photos, and any renovation records you have. Happy to answer any specific questions about the process - it's definitely worth doing right the first time rather than trying to fix issues later!

•This is really valuable insight! I'm curious about your mention of the IRS scrutinizing studies more closely - are there any specific red flags or ratios they look for that property owners should be aware of? I want to make sure I avoid any practices that might trigger additional scrutiny when I move forward with my study. Also, when you mention "disproportionate" allocated amounts, is there a general rule of thumb for what percentage of total property value typically gets allocated to shorter depreciation periods in apartment buildings?
