How do I properly write off construction materials for my rental properties?
Hey everyone, I'm in a bit of a tax situation and could use some advice on writing off construction materials for rental properties. Sorry if this is long and confusing! I run a landscaping business where I'm on job sites almost all the time. I have 4 employees who work 40-50 hours weekly, and I handle everything from planning to bookkeeping (though I send it to an accountant after). We mainly do sod work. In 2021, I started flipping houses in winter to keep my crew busy during the off-season and thought I could benefit from the tax write-offs. Last year, I bought a complete fixer-upper and renovated everything - new framing, plumbing, electrical. It's basically a new house now, finishing in January with plans to sell soon after. I wrote off all the materials as I purchased them. Recently, I bought some land to build rental condos. My goal is to transition from landscaping to construction, specifically building properties to rent out. I had a 5-year plan to use my landscaping income to fund the first 3 condos, thinking it would save on taxes. But when I met with my accountant yesterday, I was completely deflated. They said the land isn't deductible, and materials for the condos can't be directly written off - they must be depreciated over 40 years! I wanted to do this without involving banks, but if I can't deduct these expenses, I'll be paying 30% to the government. I'm not trying to avoid taxes, I just don't understand why I can't deduct materials for building rental properties that will generate taxable income. Two main questions: 1. Is there any way around this depreciation requirement? 2. Did I mess up by deducting materials for my flip house from my landscaping business? Some context: I'm an LLC S-corp. After business expenses, we're at about $195,000 annually. I usually purchase equipment to reduce that further. I'm grateful for my income, but I'm burning out working 4-5K hours yearly since 2020. I've had heart problems requiring emergency care and developed anxiety issues. My family barely gets quality time with me because I'm exhausted or irritable. The condo idea was my escape plan, but now I'm just feeling hopeless.

This is a common misunderstanding when moving from service businesses to real estate investing. Let me clarify some things: For flip properties: Materials used for a flip are NOT business expenses for your landscaping business. They're part of the "basis" of the flip property. These costs get recovered when you sell the property, not as yearly business deductions. Your accountant is right to be concerned about this - mixing these expenses could flag you for an audit. For rental properties: Construction materials for rentals are considered capital improvements, which are depreciated over the property's life (typically 27.5 years for residential rentals, not 40). This is different from repairs, which can be deducted immediately. The good news: While you can't deduct building materials immediately for rentals, there are strategies that might help: - Cost segregation studies can accelerate depreciation for certain components - Section 179 may allow deduction of some qualifying property improvements - Bonus depreciation might be available for certain components - Your active participation in real estate can potentially offset some of your other income Your landscaping profits being reinvested in real estate is smart long-term, but you need proper structuring. I'd recommend getting a second opinion from a CPA who specializes in real estate investing - they might see opportunities your current accountant doesn't.

•Thanks for the detailed explanation. What's the difference between a repair and a capital improvement? Like if I replace a bathroom sink in a rental, is that a repair I can deduct right away or an improvement I have to depreciate?

•The IRS distinguishes repairs from improvements based on whether you're restoring something to its previous condition versus making it better than before. Replacing a bathroom sink with a similar model would typically be considered a repair that can be deducted immediately. However, if you're upgrading from a basic sink to a high-end model or changing the configuration of the bathroom, that would be a capital improvement subject to depreciation. The IRS has what they call the BAR test: Betterment, Adaptation, or Restoration. If you're making the property better than its previous condition, adapting it to a new use, or restoring it from a state of disrepair, it's generally a capital improvement. Simple maintenance or fixing something that breaks is typically a repair.

I went through something similar when transitioning from my plumbing business to real estate investing. Honestly the tax situation had me completely confused until I found https://taxr.ai - it analyzes your specific situation and explains exactly how different business structures and tax strategies would apply to your case. For my situation, they showed me how to properly structure my rental property investments separate from my service business, and identified several deductions I was missing. Helped me understand which expenses needed to be capitalized vs. what could be written off immediately. The detailed report they gave me saved me about $14,000 in taxes last year and gave me a roadmap for how to structure future projects. Might be worth checking out since you're at that critical transition point between businesses. You'd upload your tax docs and business plans, and they'll analyze everything specific to your situation.

•Does it actually give advice specific to your situation or is it just generic tax info you could find anywhere? I've wasted money on "tax help" services before that just spit out templated answers.

•I'm skeptical about these online services. How do you know it's giving legitimate advice that would hold up in an audit? Did you run their recommendations by your CPA?

•It definitely gives personalized advice based on your specific situation, not generic templates. You upload your actual tax documents and business info, and it analyzes everything from your entity structure to your specific income streams and expenses. The report I got included specific tax code references for every recommendation. I did show the recommendations to my CPA, and he was impressed enough that he actually incorporated most of their strategies into my tax planning. The biggest value for me was that it found several real estate tax strategies my regular accountant wasn't familiar with since he didn't specialize in that area. They even identified that I could qualify for real estate professional status which made a huge difference in what I could deduct.

Just wanted to follow up on my skepticism about taxr.ai - I decided to try it after my accountant gave me similar depreciation advice that was killing my cash flow. The service was actually legit. It identified that my situation qualified for a cost segregation study that accelerated about 25-30% of my property's depreciation into the first year. My CPA wasn't familiar with applying this to smaller properties, but the report broke down exactly which components qualified and provided all the relevant tax code citations. They even had recommendations for how to structure my next property purchase to maximize immediate deductions. The depreciation acceleration alone saved me about $22,000 in taxes this year, which is helping fund my next project. Worth checking out if you're struggling with the same issues.

Dealing with this exact situation right now and wanted to share something that helped. After getting nowhere with the IRS helpline for weeks (literally 8+ attempts, hours on hold), I used https://claimyr.com and got connected to an actual IRS agent in under 45 minutes. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The agent walked me through exactly how to properly document and categorize construction materials for my rental properties vs. my contracting business. Turns out I was missing some key forms and had been miscategorizing certain expenses that could have been deducted immediately rather than depreciated. Saved me a ton of headache and potentially an audit. Might be worth connecting with them directly since your situation involves both a service business and real estate investments, which can get complicated.

•How exactly does this work? You pay them and they somehow get you to the front of the IRS phone queue? That sounds too good to be true.

•Yeah right. If this actually worked, everyone would use it. The IRS is intentionally understaffed to make it impossible to get help. I'm calling BS on this.

•It's actually pretty straightforward - they use an automated system that continually calls the IRS and navigates the phone tree until it gets a human, then it calls you to connect. They're basically doing the waiting for you. The service works because most people give up after being on hold for an hour or two, but their system just keeps trying until it gets through. I was skeptical too, but they only charge if they actually connect you. I got through to a specialist who specifically handles business tax questions and got clear guidance on exactly how to handle my situation.

I have to admit I was completely wrong about Claimyr. After my skeptical comment, I decided to try it anyway out of desperation - I had a similar issue with construction materials and the 27.5 year depreciation was killing my cash flow. Got connected to an IRS agent in about 35 minutes who explained that certain components of my construction could actually qualify for 5-year or 7-year property classification instead of 27.5 years. They walked me through exactly how to document everything properly for a cost segregation approach. The agent also clarified when I could use Section 179 for certain improvements even though they're part of a residential rental. Definitely worth the connection fee to get actual answers from someone with authority instead of guessing or getting generic advice.

One strategy that worked for me was setting up a separate construction company that builds/renovates the properties, then "sells" the improved property to my rental LLC at a markup. The construction company can deduct materials as COGS, and the rental company gets a higher basis. This is completely legal if properly structured and documented! Talk to a real estate-focused CPA about this approach. My regular accountant wasn't familiar with it, but my new real estate tax specialist helped set everything up correctly. The IRS cares about substance over form, so you need legitimate business reasons and proper documentation.

•This sounds interesting but also complicated. Did you need to get multiple business licenses or insurance policies? And how do you prove to the IRS that the "sale" between your companies is legitimate and not just a tax dodge?

•You'll need proper licensing and insurance for both businesses regardless - operating without them is risky no matter what. The construction company should have contractor licensing and liability insurance, while the rental LLC needs its own liability policy. For legitimacy, you need to treat each entity as a completely separate business with its own books, accounts, and operations. The construction company should market to and perform work for other clients too, not just your rental business. The sales between companies need to be at market rates with proper contracts and documentation. You'll want separate tax IDs, bank accounts, and maintain corporate formalities like meeting minutes. I'd also recommend having the construction company owned by a different person than the rental company if possible (spouse, family member) to further establish separation.

Be really careful with writing off your flip materials from your landscaping business! I did this exact thing and got audited. The IRS reclassified everything, disallowed my deductions, and hit me with penalties and interest. My $12k tax savings turned into a $20k+ nightmare. The IRS is pretty strict about keeping these activities separate. For flips, you should be tracking all costs (materials, labor, permits, etc.) and adding them to the property's basis. You'll recoup these when you sell. If you've already been writing these off as landscaping business expenses, consider filing amended returns before they catch it.

•Did you have any warning signs before the audit happened? Like did they send letters first or just launch straight into a full audit?

I'm a rental property owner and wanted to add: while you can't immediately deduct the materials for building your rentals, consider exploring the BRRRP strategy (Buy, Rehab, Rent, Refinance, Repeat). This lets you pull cash out after establishing equity, which is untaxed since it's debt, not income. Also, look into Qualified Business Income deductions for your rental activity if you can qualify as a "real estate professional" for tax purposes. With your construction background, you might meet the hours requirement. For your specific question about the flip materials you already deducted - that's problematic. Those should have been capitalized to the property's basis. Consider talking to a tax attorney about amendment options before an audit happens.
