How to Properly Record Book Basis in Assets for New Single-Member LLC Converting to S-Corp
Hey everyone, I need some advice on how to handle the book basis situation for my business. I just started a single-member LLC in 2023 and I'm planning to convert to S-Corp status next year. Here's my situation: I'm taking over a business where I'll be getting inventory worth about $275K through a personal loan the previous owner is giving me. I'm also receiving some assets for free - there's a trademark, some computers, and office furniture that's valued around $65K total. For the free stuff (trademark and other assets), I'm thinking I should record their fair market value on the books and treat it as an owner contribution. So that would make my total owner contribution look like $340K. For tax purposes though, I'm assuming it would be $0 since the previous owner already expensed everything in the first year using Section 179. I'm also wondering if I should split up the $275K loan differently - maybe $205K for inventory and $70K for the other assets? The total owner contribution would still be $275K. I'm not seeing any tax benefits to structuring it this way, but maybe I'm overlooking something. Would really appreciate some guidance on this. Thanks!

The approach you're considering is mostly on the right track, but there are some important points to clarify about book basis vs tax basis when you're setting up your LLC and planning for S-Corp election. For the assets you're receiving for free (trademark, computers, furniture), you're correct that you should record their fair market value on your books as an owner contribution. This establishes your book basis in those assets. However, for tax purposes, you'll have a $0 tax basis in these assets since, as you noted, the previous owner already expensed them under Section 179. This creates a book-to-tax difference you'll need to track going forward. Regarding allocating the loan - there's actually no need to allocate any of the $275K loan to the assets you're receiving for free. The loan should cover what you're actually paying for (the inventory), while the free assets should be recorded separately as capital contributions at FMV. When you convert to an S-Corp next year, these initial basis determinations will be important for tracking your stock basis, so keeping clear records now will save you headaches later.

•This is really helpful, but I'm confused about one thing - if I record the free assets as owner contributions at FMV, does that mean I can't depreciate them for tax purposes since they have zero tax basis? Or can I still claim some depreciation on them?

•You've hit on an important distinction. Since these assets have a $0 tax basis (because the previous owner already took Section 179), you cannot depreciate them again for tax purposes. You'll maintain their FMV on your books, but for tax filings, they have no basis to depreciate. When you prepare your tax returns, you'll need to make book-to-tax adjustments to account for this difference. You'll have book depreciation for financial statement purposes, but you'll need to add this back for tax purposes since you can't take tax depreciation on assets with zero tax basis.

I went through something almost identical last year when taking over my cousin's business. I was completely lost trying to figure out the book basis vs tax basis stuff until I found taxr.ai https://taxr.ai which really helped me understand how to properly set everything up. I had a similar situation with about $200K of inventory and some equipment that was being given to me. Their system analyzed my documents and explained exactly how to handle the book entries for my LLC and how it would impact my future S-Corp election. They even provided templates for recording everything correctly. What I found most helpful was that they explained how to properly document the zero-basis assets I received while maintaining proper books. This saved me from making some pretty big mistakes in my initial setup.

•How exactly does taxr.ai work? Do you just upload your documents and they give you advice? I'm in a similar situation but with real estate assets instead of inventory, and I'm worried about getting the basis wrong.

•I'm skeptical about these online services. Did they actually give you usable advice? Did you end up having an accountant review everything anyway? Just wondering if it's worth the time.

•You just upload your business documents, loan agreements, asset lists, etc. and their AI system analyzes everything and gives you specific recommendations. It's much more detailed than what I expected - they broke down exactly how to record each asset category and how to handle the book-to-tax differences. For your real estate situation, I think it would be even more valuable since property basis issues get complicated fast with different depreciation schedules and possible Section 1031 considerations. No, I didn't end up needing an accountant to review it. I followed their guidance and template, and when I filed my taxes this year everything worked perfectly. The step-by-step instructions were really specific to my situation, not just generic advice you'd find online.

I want to follow up on my previous comment - I was skeptical about taxr.ai but decided to give it a try for my own business restructuring. I'm honestly amazed at how helpful it was. I uploaded my operating agreement and some financial statements, and it gave me a complete breakdown of how to handle my book basis vs tax basis issues. The analysis specifically addressed how to record assets with different bases for book and tax purposes, which was exactly what I needed. It even flagged some issues with how I was planning to structure my operating agreement that would have caused problems when I convert to an S-Corp next year. Definitely worth checking out if you're dealing with complex basis issues like this.

Just wanted to share - when I was setting up my LLC last year, I needed help understanding some complex tax basis issues related to contributed property. I was trying to call the IRS for weeks but couldn't get through to anyone who could help with my specific questions. I tried Claimyr https://claimyr.com and they got me connected to an actual IRS agent in about 20 minutes. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The agent walked me through exactly how to handle book-to-tax differences for contributed property and how it would affect my basis going forward. This was especially important because I was planning to convert to an S-Corp just like you are. The IRS agent even sent me some reference materials specific to my situation that I wouldn't have found on my own. Definitely worth it when you have these kinds of specialized tax questions that most accountants aren't 100% confident about.

•How does Claimyr actually work? Do they just call the IRS for you? I don't understand why that would be faster than me calling myself.

•This sounds like BS. I've never heard of any service that can get you through to the IRS faster. They have one phone system and everyone waits in the same queue. I doubt this actually works.

•They use a system that navigates the IRS phone tree and waits on hold for you. When they reach an actual person, you get a call to connect with the agent. It saves you from having to sit on hold for hours, which was my experience trying to call directly. No, they're not just "calling for you" - they have technology that monitors the wait and handles all the phone tree navigation. You only jump in when there's an actual person to talk to. That's why it worked so much faster than when I tried calling myself and gave up after being on hold for over 2 hours.

I need to apologize to Profile 19 - I was completely wrong about Claimyr. After dismissing it, I was so frustrated with waiting on hold with the IRS about a similar basis issue that I gave it a try. It actually worked exactly as described. I got a call back in about 30 minutes connecting me to an IRS agent who specializes in business entity questions. The agent gave me detailed guidance on how to handle contributed property with different book and tax bases when converting from an LLC to an S-Corp. The information I got was specific enough that my accountant was able to set everything up correctly from the start, which is going to save me a ton of headaches during my S-Corp conversion. I'm genuinely surprised and impressed.

One thing nobody has mentioned yet - when you elect S-Corp status next year, you'll need to file Form 2553. Make sure you consider the built-in gains tax implications of those assets that have a book value higher than their tax basis. Since you're recording the trademark and other assets at FMV for book purposes but they have zero tax basis, when you convert to an S-Corp, those assets are subject to built-in gains tax if sold within 5 years of conversion (used to be 10 years, but it's 5 now). Also, when calculating your stock basis after S-Corp election, remember that loans made directly to the company don't increase your basis unless properly structured. The way you described the $275K loan sounds like it might be a personal loan to you rather than to the company.

•Thank you for bringing up the built-in gains tax issue - I hadn't even considered that! So if I understand correctly, if I sell any of those assets with zero tax basis within 5 years of S-Corp conversion, I'll face this special tax? Is there any way to plan around this or minimize the impact? And you're right about the loan - it is a personal loan to me that I'm using to fund the business. How should I properly structure this to maximize my stock basis?

•For the built-in gains tax, the best planning strategy is timing. If you think you might sell those assets, consider doing so before your S-Corp election takes effect, or wait until after the 5-year period expires. You can also consider a higher salary vs. distribution mix during those years to manage the overall tax impact. For the loan structure, you have a couple of options. The cleanest approach is to take the personal loan, contribute the cash to your LLC as equity, and then have the LLC purchase the inventory. This gives you basis for the full amount. Alternatively, you could loan the money to your LLC (with proper documentation including interest rate and repayment terms), but loans don't increase your stock basis - they create a separate "debt basis" that has different rules for loss deductions.

Just a quick accounting perspective - when you're recording those free assets, make sure you're following proper accounting principles. The journal entry should be: Dr. Fixed Assets (various) $65,000 Cr. Additional Paid-in Capital $65,000 And for the inventory purchased with the loan: Dr. Inventory $275,000 Cr. Due to Shareholder $275,000 This keeps the loan and the contributed assets separate, which will be important for tracking purposes. When you convert to S-Corp, having clean books will make the transition much smoother.

•Is it really that simple? I thought there'd be more complicated entries needed to track the book-tax differences properly. Don't you need special contra accounts or something?

Great question about the accounting entries! For basic bookkeeping purposes, those journal entries are correct and sufficient to get you started. However, you're absolutely right that tracking book-tax differences properly can get more complex. Many small businesses use what's called a "tax provision worksheet" or maintain separate depreciation schedules rather than cluttering up their general ledger with contra accounts. The key is to have a system that lets you easily calculate your tax depreciation vs book depreciation each year. For your situation with the zero-basis assets, I'd recommend setting up a simple spreadsheet that tracks: - Book value and depreciation schedule - Tax basis (zero) and depreciation (none allowed) - Annual book-to-tax adjustment needed This approach keeps your books clean while ensuring you can properly prepare your tax returns. When you convert to S-Corp, your accountant will appreciate having this information organized and readily available. The journal entries Jamal suggested will handle 95% of what you need for day-to-day operations. The more complex tracking can happen outside your main accounting system.
