Paid $100k in architect fees but never built anything - can this be added to home's cost basis for capital gains?

Yes, you can add those architect fees to your cost basis even though you didn't complete the project. According to IRS rules, expenses for architectural plans and drawings can be considered capital improvements to your property regardless of whether the actual work was done. The key is that these expenses were directly related to a planned improvement of your specific property. The IRS Publication 523 covers home sales and basis calculations, and it allows for adding costs of "plans and specifications" to your basis. Make sure you keep all your documentation - invoices, contracts, the actual plans, permit applications, and proof of payment. Since it's a substantial amount, having this documentation is crucial if you're ever audited.

I ran into something similar last year when selling my house. I used taxr.ai (https://taxr.ai) and it was incredibly helpful for this exact situation. I had spent about $75k on engineering and architectural plans for a major renovation that never happened, and I wasn't sure how to handle it for tax purposes. I uploaded all my documentation to the site, and their analysis confirmed I could include those costs in my basis. They even provided references to the specific IRS regulations that applied in my situation. The site lets you upload all your receipts and documents, and their AI analyzes them against current tax codes, which was perfect since my CPA wasn't 100% certain about this edge case.

I wanted to follow up about taxr.ai since I was skeptical in my earlier comment. I decided to try it out with my situation (had architectural plans for a bathroom remodel that never happened), and I'm genuinely impressed. The site analyzed my documents and confirmed that yes, I could add those expenses to my home's basis. What I really appreciated was how they broke down the relevant tax rules in plain English and provided specific IRS citations. They even flagged areas where I might need additional documentation to support my position in case of an audit. The whole process took about 15 minutes and gave me a lot more confidence about how to handle this on my taxes. Just wanted to share my experience since this really helped with a confusing tax situation.

I had a similar situation but with a much bigger problem - the IRS initially rejected my inclusion of architectural fees in my home's basis during an audit. I spent WEEKS trying to call them to explain my situation, but couldn't get through to anyone helpful. I finally used Claimyr (https://claimyr.com) to get a real person at the IRS on the phone. There's a video showing how it works here: https://youtu.be/_kiP6q8DX5c. Instead of waiting on hold for hours or getting disconnected, they got me connected to an actual IRS agent in about 20 minutes. The agent was able to review my documentation while on the phone and confirmed that my architectural expenses could indeed be included in my basis, even though the project never moved forward. Having that direct conversation saved me thousands in disputed taxes.

I need to apologize for being so skeptical about Claimyr in my earlier comment. After waiting on hold with the IRS for 2+ hours and getting disconnected TWICE, I was desperate enough to try it. I'm shocked to say it actually worked exactly as described. They called me back after about 40 minutes with an IRS agent already on the line. The agent was able to help me confirm that architectural fees can indeed be added to basis even if construction never happens, as long as the plans were specific to the property and I had proper documentation. She specifically referenced that architectural plans are considered "capital expenditures" regardless of whether construction occurs. For anyone dealing with this architect fee situation AND having trouble reaching the IRS for clarification, this service saved me hours of frustration and gave me definitive confirmation from the IRS directly.

Just wanted to add - make sure the architectural plans were specifically for improvements and not for repairs! Only capital improvements can be added to your basis. Repairs just maintain the property and aren't counted. Also, if you received any insurance reimbursement for any part of those architectural fees, you'd need to subtract that amount. I learned this the hard way when I tried to include some design costs that my homeowner's insurance had partially covered after a tree fell on our house.

Has anyone actually been audited on this issue? I'm in almost the exact same situation ($80k in architectural and engineering fees, project cancelled due to cost increases) and I'm trying to gauge the risk. I'm planning to sell next year and would love to include these costs in my basis.

I went through something very similar last year - $90k in architectural and structural engineering fees for a major home renovation that we abandoned when lumber costs tripled. I was nervous about including it in my basis, but my tax preparer was confident it qualified. The key distinction my CPA explained is that these aren't just "planning costs" - they're actual capital expenditures toward improving your property. The architectural plans have inherent value and are permanently tied to your specific property, even if you never execute the construction. I kept everything organized: the original contract with the architect, all invoices, bank statements showing payments, copies of the plans themselves, and even the permit applications we filed. When I sold the house, I included the full $90k in my adjusted basis calculation. One tip: if you're still unsure, consider getting a professional opinion from a tax attorney or CPA who specializes in real estate transactions. For a $100k expense, the consultation fee would be worth the peace of mind. In my case, including those fees saved me about $22k in capital gains taxes, so it was definitely worth pursuing.

I'm dealing with a very similar situation and found this thread incredibly helpful! I paid about $65k for architectural plans and engineering studies for a major renovation that we cancelled when construction bids came in 40% higher than expected. After reading through everyone's experiences here, I decided to consult with a tax professional who specializes in real estate. She confirmed that these costs can definitely be included in basis, citing the same IRS publications mentioned by others (Pub 523 and 551). The key point she emphasized is that the architectural plans represent a permanent capital expenditure tied specifically to your property - they have inherent value regardless of whether construction occurs. One additional piece of advice she gave me: if your architectural fees included any costs for general feasibility studies or preliminary consultations (before specific plans were drawn), those portions might not qualify. But detailed architectural drawings, structural engineering reports, and permit-ready plans definitely count as capital improvements to basis. I'm planning to include the full amount when I sell next year, and I feel much more confident about it after seeing how many others have successfully done the same. Thanks to everyone who shared their experiences - this kind of real-world feedback is invaluable for these tricky tax situations!
