Renting commercial space to my own LLC - fair rental rates between related businesses
So here's my situation... My family and I own a commercial building through an LLC (let's call it "Property LLC"). It's owned by me, my brother, and my parents with equal shares. I also have my own separate business (a marketing agency) that operates as a single-member LLC with just me as the owner. My marketing agency needs office space, and we've decided to set up shop in the family-owned building. The arrangement makes sense logistically, but I'm confused about how to structure the rent payment. How do we determine a fair rental price between these two related LLCs? Are there specific IRS rules about rental agreements between businesses with common ownership? The Property LLC needs income to cover mortgage, insurance, and maintenance, but I also don't want to create any tax issues or raise red flags. I've heard something about "arm's length transactions" but don't really understand what that means in practice. Has anyone dealt with a similar situation before? What documentation should we have in place? Thanks for any insight!

You'll want to establish what's called an "arm's length" rental rate - basically what you'd charge any unrelated business renting the same space. This protects you from IRS scrutiny since they look closely at related-party transactions. The best approach is to research comparable commercial rental rates in your area for similar spaces. Document this research thoroughly - collect listings, talk to commercial real estate agents, and keep records of similar properties' rental rates. This documentation is your justification if ever questioned. Make sure to create a formal, written lease agreement between the LLCs just like you would with any tenant. Include standard terms like duration, payment schedules, maintenance responsibilities, etc. Have both entities properly sign it. Keep all transactions clean and documented. The family LLC should deposit rent payments into its account and use that money for building expenses. Don't mix funds between entities.

•This is super helpful, thanks. Quick follow-up - does the rental income from my marketing LLC to the property LLC get treated as passive income? And would the property LLC be able to deduct expenses like mortgage interest, property taxes, and depreciation against that income?

•Yes, the rental income received by your property LLC would typically be classified as passive income for the LLC and its members. The property LLC would be able to deduct legitimate business expenses including mortgage interest, property taxes, insurance, maintenance costs, and depreciation against the rental income it receives. Make sure your property LLC maintains separate books that clearly track all rental income and associated expenses. This clean accounting helps demonstrate the business purpose of the arrangement and supports any deductions claimed.

Been through this exact situation and found https://taxr.ai incredibly helpful for my related-party lease situation. I was stressing about setting the right rental rate between my construction business and the property LLC I share with my siblings. The IRS scrutinizes these arrangements so I needed to get it right. I uploaded our draft lease agreement and comparable market listings to taxr.ai and they analyzed everything against relevant IRS guidelines for related-party transactions. Their report highlighted several issues I hadn't considered, including documentation requirements for establishing market rates and specific lease terms that could trigger unwanted scrutiny. They also helped identify optimal expense allocation between the entities that I would've completely missed. Definitely smoothed out the whole process!

•How long did it take to get an answer back from them? I'm in a similar situation but need to finalize my lease arrangement by next week.

•Sounds interesting but I'm skeptical. Did they actually review your specific situation or just give you generic advice that I could find anywhere? I've been burned before by services promising personalized tax guidance but delivering glorified templates.

•I got their analysis back within about 48 hours, which was pretty impressive considering the complexity of what I submitted. They even sent me a preliminary response when they needed clarification on something specific to my situation. They definitely provided personalized analysis, not generic templates. They referenced specific sections of my lease draft and pointed out issues unique to my particular ownership structure. They cited relevant tax code sections and even included recent ruling examples affecting related-party commercial leases. What really convinced me was when they identified a potential issue with how I had structured the maintenance responsibilities that could have created problems during an audit.

I have to admit I was wrong about taxr.ai. After my skeptical comment, I decided to try them for my own situation with my photography business renting from my family's property partnership. Their analysis was surprisingly detailed and caught several issues with my lease draft that would have created tax headaches. They specifically identified that the rent I planned to charge was about 15% below market rate based on comparable properties they researched, which could have triggered related-party transaction scrutiny. They also spotted that my lease was missing crucial language about common area maintenance charges that's standard in commercial leases. The documentation they provided on establishing market rates has already been invaluable for my records. Definitely worth it for the peace of mind alone.

If you're struggling to get clear answers about your rental situation, you might want to check out https://claimyr.com. I wasted weeks trying to get through to someone at the IRS about related-party rental rules for my business. Kept getting disconnected or waiting hours only to get vague answers from someone who couldn't address my specific scenario. Finally tried Claimyr's service and they got me connected to an actual IRS agent in about 20 minutes. The agent walked me through exactly what documentation I needed for my related-party lease and gave me specific guidance on how to establish a defensible market rate. You can see how it works in this demo: https://youtu.be/_kiP6q8DX5c Saved me literally days of frustration and possibly an audit headache down the road. The agent even emailed me reference materials specific to my situation after the call.

•How exactly does this work? Do they just call the IRS for you? Couldn't I just do that myself instead of paying someone else to do it?

•Yeah right, nobody gets through to a real IRS agent that quickly. I spent 4 hours on hold last week and got disconnected twice. This sounds like a scam to me - there's no magic back door to the IRS.

•They don't just call for you - they use a system that navigates the IRS phone tree and holds your place in line. Then when they're about to connect with an agent, you get a callback so you can speak directly with the IRS. You're not paying someone to talk to the IRS for you - you're paying to skip the endless hold times. I was skeptical too, but the average IRS wait time right now is over 90 minutes if you can even get through at all. They got me connected in about 20 minutes while I was working on other things. Think of it like paying for a FastPass at an amusement park - same ride, just without wasting your whole day in line.

I need to publicly eat my words about Claimyr. After my skeptical comment, I was still stuck with questions about my commercial rental situation that online research couldn't answer. Decided I had nothing to lose and tried the service. Not only did I get connected to an IRS representative in about 15 minutes (compared to my previous failed attempts), but I got connected to someone in the business division who actually understood my specific question about related-party commercial leases. The agent clarified exactly what documentation I needed to maintain and confirmed that as long as I'm charging market rate rent and have proper documentation, I'm good to go. They even sent me follow-up information through their secure messaging system. Completely worth it just for the time saved and stress avoided.

Just a warning from personal experience - make sure you're also checking local zoning requirements before finalizing anything. I had a similar setup with two LLCs and got everything right tax-wise, but then got hit with zoning violations because the building wasn't properly classified for my business type. Cost me thousands to resolve.

•Thanks for bringing this up! I hadn't even thought about zoning issues. Our building is in a mixed commercial zone, but I should definitely double-check the specific usage restrictions. Were there any particular resources you found helpful for navigating this?

•Your local county or city planning department is the best resource. They usually have online portals now where you can look up the zoning classification for your property. You want to check both the general zone (commercial, mixed-use, etc.) and any specific use restrictions or required permits for your type of business. In my case, I needed a special permit for client parking that wasn't initially obvious from the general zoning description. I'd recommend scheduling a meeting with a planner if possible - they're usually pretty helpful if you're upfront about what you're trying to do.

Has anyone mentioned insurance considerations? When I had this arrangement, my insurance agent pointed out that we needed to update policies for both LLCs. The property LLC needed landlord coverage, and my business LLC needed renter's insurance with proper liability limits. Without the formal lease agreement, there would've been coverage gaps.

•Excellent point! When I set up my rental arrangement, I discovered our property insurance specifically excluded coverage for related-party tenants unless we had certain documentation in place. Had to get a special endorsement added to the policy.

One thing that hasn't been mentioned yet - make sure you're handling the security deposit correctly if you decide to require one. Even though it's between related entities, you still need to follow state landlord-tenant laws for how security deposits are held and returned. In my state, security deposits have to be kept in a separate escrow account and there are specific timeframes for returning them after the lease ends. I made the mistake of just keeping the deposit in our general business account initially, which could have created legal issues if there had been a dispute. Also consider whether you want to include annual rent increases tied to inflation or market rates in your lease agreement. This helps maintain the arm's length nature of the transaction over time and prevents the rent from becoming artificially low compared to market rates as years go by.

•Great points about the security deposit and rent increases! I'm just getting started with understanding all these requirements. For the annual rent increases, how do you typically structure that in the lease? Is it better to tie it to a specific index like CPI or just do a flat percentage increase each year? And do you have any recommendations for finding out the specific security deposit rules for my state?

Another important consideration that often gets overlooked is maintaining separate bank accounts and financial records for each entity throughout the entire arrangement. Even though you're dealing with related LLCs, the IRS wants to see that each entity is truly operating independently. Make sure the Property LLC has its own business checking account where rent payments are deposited, and all property-related expenses (mortgage, insurance, maintenance, etc.) are paid from that account. Your marketing agency LLC should pay rent from its own business account with proper documentation like invoices or payment memos. I'd also recommend having the Property LLC issue proper invoices to your marketing agency each month, just like any other landlord would. This creates a clear paper trail and reinforces the business relationship between the entities. Keep copies of all rent payments, invoices, and any correspondence about the lease arrangement. One more tip - consider having an annual review where you reassess the rental rate against current market conditions. Document this review process to show you're actively maintaining arm's length pricing. This ongoing diligence can be valuable if the IRS ever questions the arrangement years down the road.

•This is exactly the kind of detailed advice I was hoping to find! The point about issuing monthly invoices is something I definitely wouldn't have thought of on my own. Quick question - when you mention having an annual review of the rental rate, do you document that review even if you decide not to change the rent? I'm thinking it might be good to have written justification for why we're keeping the current rate if it's still within market range. Also, for the separate bank accounts, should the Property LLC be set up as a completely separate business entity for banking purposes, or is it okay that it's clearly connected to our family since we're all listed as members? I want to make sure we're not accidentally creating any red flags while trying to do everything properly.
