Definition of primary residence for tax purposes with raw land purchase & farming plans?
Hey tax pros! I'm super confused about what counts as a "primary residence" for tax purposes. I'm in the process of buying 12 acres of raw land for $68,000 and getting a land loan. Planning to start a small farm operation on about 4 acres. There's an old hunting cabin on the property that I could renovate to make it livable - nothing fancy but would have the basics. My question is: If I fix up this cabin and actually live there while developing the farm, can I classify it as my primary residence for tax purposes? Would this help with any deductions related to the mortgage interest on the land loan? I currently rent an apartment in town but would move to the property once the cabin is habitable (probably 3-4 months of renovation work). The loan officer mentioned something about tax benefits if it becomes my primary residence vs just being classified as investment/farm property, but wasn't super clear on the details. Anyone know the actual definition and requirements for something to count as a primary residence with the IRS? And what tax advantages would I actually get if it qualifies? Thx!!

The IRS generally defines your "primary residence" as the home you live in most of the time. For tax purposes, you can only have one primary residence at a time. If you genuinely move into the renovated cabin and it becomes the place where you actually live (receive mail, register to vote, etc.), then yes, it could qualify as your primary residence. The main tax advantage would be potential mortgage interest deductions. If you use the property as your primary residence for at least 2 of the 5 years before selling, you might also qualify for capital gains exclusion (up to $250,000 for single filers or $500,000 for married filing jointly). For the farming aspects, that would be considered a separate business activity. You'd likely need to file Schedule F for the farm income/expenses, which is separate from your personal residence deductions.

•Thanks for explaining! So if I split the loan between personal residence and farm business, how does that work for deductions? Like if 1 acre is for the cabin/home and 11 acres for farming? Do I need to get the loan split officially or just do the math at tax time?

•You'll need to allocate the loan interest proportionally between personal and business use. If 1 acre out of 12 is for personal residence, you could allocate 1/12th of the interest to mortgage interest (potentially deductible on Schedule A if you itemize) and 11/12ths to business interest (deductible on Schedule F). I recommend documenting this allocation method clearly and consistently. You don't necessarily need separate loans, but some lenders might require different loan products for residential vs. agricultural purposes, so discuss this with your lender early in the process.

After going through a similar situation last year, I found this amazing tool at https://taxr.ai that helped me figure out the exact tax implications of my land purchase. I had 20 acres with a small cabin that I converted to my primary residence while starting a small organic farm. The tricky part was figuring out how to properly allocate expenses between personal and business use. Taxr.ai analyzed all my documents and showed me exactly how to structure everything to maximize legitimate deductions. They even helped identify farm-specific tax benefits I had no idea existed! The guidance was super specific to my situation, which was way better than the generic advice I kept finding online.

•Was it expensive? And how exactly does it work - do you just upload your documents and it gives you advice? I'm looking at a similar situation but with a slightly different setup (manufactured home on agricultural land).

•Sounds interesting but I'm skeptical. How does it handle the primary residence test? I've heard the IRS is pretty strict about that 2-out-of-5-years rule, especially with properties that are partially business. Did it actually help with audit protection?

•It's actually really reasonable for what you get. You upload your documents (deed, loan papers, floor plans, etc.) and it uses AI to analyze everything and provide specific guidance. Within about a day I had detailed recommendations tailored to my situation. The tool gives clear guidance on the primary residence test and documentation needed to satisfy the IRS requirements. It advised me to keep utility bills, change my address on all official documents, register to vote using that address, etc. It also recommended taking dated photos of the renovation progress and keeping all receipts. These aren't just generic tips - they're tailored to your specific situation and property type.

Just wanted to follow up and say I tried taxr.ai for my situation and it was incredibly helpful! I was surprised by how detailed the analysis was. It showed me exactly how to document my living situation to satisfy the primary residence requirements, plus gave me a complete breakdown of which expenses could go where for tax purposes. The best part was the clear explanation of how to handle the dual-use property. It turns out I can actually take both the qualified business income deduction for the farm portion AND get mortgage interest deductions for the residential part if I document everything properly. The tool generated a custom record-keeping template that makes tracking everything super easy. Definitely worth checking out if you're in this situation!

I had a nightmare dealing with the IRS on a similar property situation last year. Tried calling them about 16 times before finding https://claimyr.com which got me through to an actual IRS agent in less than 20 minutes! You can see how it works here: https://youtu.be/_kiP6q8DX5c I had purchased raw land with a structure and couldn't get a straight answer from anyone about how to handle the taxes. The IRS agent I finally spoke to confirmed exactly what I needed to document to establish primary residence status and how to properly allocate the mortgage interest between personal and business use. Saved me thousands in potential penalties from doing it wrong.

•Wait, how does this actually work? Does it just keep calling the IRS for you or something? I've literally spent hours on hold with them trying to get answers about my rental property.

•Yeah right. Nothing gets you through to the IRS faster. I'll believe it when I see it. I've been trying for 3 months to get someone on the phone about my amended return.

•It actually uses automated technology to navigate the IRS phone system and holds your place in line. When an agent is about to pick up, it calls your phone and connects you directly. It's not magic, just smart technology that does the waiting for you. Yes, it really works! It saved me from calling the IRS myself repeatedly and waiting on hold for hours. I was connected to an agent in about 18 minutes, and they were actually really helpful once I explained my situation with the land purchase and primary residence questions.

I have to eat my words. I tried Claimyr yesterday out of desperation and got through to an IRS agent in about 15 minutes! After months of trying to reach someone about my property tax situation, I finally got clear answers. The agent confirmed that converting a structure on raw land to a primary residence is absolutely valid for tax purposes as long as you actually live there (they look for things like utility bills, driver's license address, etc.). They also explained exactly how to document the split between personal and business use when filing. The agent even sent me specific IRS publications about farm property that I didn't know existed. Worth every penny not to spend another 3 months trying to get through!

Just a heads up on something that bit me when I did this - pay attention to local zoning laws too, not just IRS rules. I converted a shed on my farm property to live in while developing the land, properly documented everything for tax purposes, but then got hit with fines from the county because the structure wasn't zoned for residential use. Had to get retroactive permits and do some expensive modifications.

•Good point! Did you have any issues with the loan company? My bank is giving me grief about living in the structure on my land because they say the loan was for "agricultural purposes" not residential. Did you have to refinance or anything?

•I did have some issues with my lender. They initially flagged my account for "improper use" because the loan was classified as agricultural. I ended up having to refinance into a different type of loan that allowed for mixed use (residential + agricultural). Check your loan documents carefully - there's often specific language about permitted uses. Some ag loans explicitly prohibit using any structures for residential purposes without prior approval. Better to know that upfront than get a nasty letter from the bank later!

Has anybody here dealt with claiming home office deductions when your primary residence is on farm property? I'm in a similar situation (built a cabin on my farm land) and use part of it exclusively for farm management. Do I claim that on Schedule F or as a home office deduction?

•You can claim home office for farm business on Schedule F directly. Line 32 is for "home office expenses" if you use the simplified method ($5 per square foot up to 300 sq ft). If you use actual expenses, you'll need Form 8829. Either way, the deduction goes on Schedule F since it's farm business, not some other type of business.

Another thing to consider - if you're getting an agricultural loan with reduced interest rates but then primarily using the property as a residence, some lenders consider that loan fraud. Make sure your lender knows your full intentions upfront. My neighbor got in serious trouble for this exact situation when the bank found out he was living on the "farm" property full-time and only had a small garden rather than a commercial farm operation.

•Whoa, that's scary! My loan application clearly states I'll be living on the property while developing the farm business. The loan officer seemed fine with it, but I'll double-check that it's documented in the loan papers. Definitely don't want to accidentally commit fraud! I'm planning to actually farm about 4 acres commercially (market garden) so hopefully that's sufficient to satisfy the agricultural part.

•You're doing things right by being transparent. As long as you're genuinely farming commercially (selling products, not just growing for personal use) and have that documented in your business plan and loan application, you should be fine. Get something in writing from your loan officer confirming they understand you'll be living there while operating the farm business. And keep good records of your farm business development! Taking dated photos of land clearing, planting, equipment purchases, etc., creates a paper trail showing you're legitimately developing an agricultural business as stated in your loan application.

One important thing to keep in mind is the timing of when you establish residence vs when you start claiming it as your primary residence for tax purposes. The IRS looks at where you actually live for the majority of the year, so if you're renovating for 3-4 months while still renting in town, you'll want to be careful about when you officially claim the cabin as your primary residence. I'd suggest keeping detailed records of when you actually move in full-time (utility hookups, mail forwarding, voter registration change, etc.) and use that date as your official residence change date for tax purposes. Don't try to claim it as primary residence while you're still primarily living in the apartment - that could create issues if audited. Also, since you mentioned this is raw land, make sure the cabin renovation meets local building codes for habitable structures. The IRS generally expects a primary residence to be a structure suitable for year-round occupancy with basic amenities (plumbing, electricity, heat). Document the improvements you make to ensure it meets these standards.

•This is really helpful advice about timing! I hadn't thought about the fact that I can't claim it as primary residence while I'm still mainly living in my apartment. That makes total sense from an audit perspective. Quick question - when you say "basic amenities," does that mean I need full plumbing or would a composting toilet and water source be sufficient initially? The cabin has electricity but the plumbing situation is pretty primitive right now. I'm planning to upgrade it gradually as I can afford it, but want to make sure I'm not jumping the gun on claiming primary residence status before it truly qualifies. Also, should I notify my current landlord about my move-out date based on when the cabin is actually habitable, or can I give notice earlier if I'm confident about the timeline? Trying to coordinate all these moving pieces without creating tax complications!

•Great question about the amenities! The IRS doesn't have super specific requirements, but they generally expect a residence to have the basics for year-round living. A composting toilet and reliable water source could work initially, especially in rural areas where that's more common. The key is that it needs to be genuinely livable - you're actually sleeping there, cooking, etc. I'd recommend getting at least basic plumbing functional before officially claiming it as your primary residence, just to be safe. Document everything with photos and receipts as you make improvements. For the landlord timing, I'd base your notice on when you realistically expect to be living at the cabin full-time, not just when renovations start. Better to give a bit more notice than to rush the transition and create issues with the IRS about when you actually changed residences. Keep in mind you'll need to update your address with banks, insurance, voter registration, etc. all around the same time to support your claim that it's truly your primary residence.

This is a great question and I can see you've gotten some solid advice already! Just wanted to add a few points from someone who went through a similar process last year. One thing I learned the hard way is to document EVERYTHING from day one. I created a simple spreadsheet tracking all expenses (renovation materials, utilities, loan payments, etc.) and categorized them as either "personal residence" or "farm business" related. This saved me tons of time at tax season and would be crucial if ever audited. Also, regarding the mortgage interest deduction - keep in mind that with the current standard deduction being so high ($13,850 for single filers in 2023), you might not benefit from itemizing unless you have other significant deductions. Run the numbers both ways to see what actually saves you more money. One last tip: consider consulting with a tax professional who specializes in agricultural properties before you finalize your setup. The upfront cost is usually worth it to make sure you're structuring everything optimally from the start, especially with the complexity of mixed-use property. Better to get it right initially than try to fix it later! Good luck with your farm venture - sounds like an exciting project!
