Selling my Corporation to another Corporation - Tax Efficient Way to Extract Money from C Corp? Downsides?
I've been diving into tax law recently and trying to figure out the most efficient way to get money out of my C Corporation. I know the standard approach is taking dividends, but then I'm looking at a 0/15/20% tax hit depending on my bracket. I had this idea and wanted to check if it works: What if I sell a different corporation (let's call it CorpB) to my main C Corp (CorpA)? That way, I'd only pay tax on the gain from selling CorpB, right? And the money I get from CorpA (as the purchase price for CorpB) wouldn't be considered dividends from CorpA. If CorpA has enough cash reserves to purchase CorpB, what are the potential downsides to this approach? I'd still maintain 100% ownership of both corporations - CorpA would just technically own CorpB. Is there anything problematic about this ownership structure? Can I legally own CorpA which then owns CorpB? Would appreciate any insights from those with experience in corporate tax structuring!

This is a classic tax planning strategy, but there are several important things to consider before proceeding. When you sell Corporation B to Corporation A, you're correct that you'll only pay capital gains tax on the profit from the sale rather than dividend tax rates. However, the IRS is well aware of this strategy and has regulations in place to prevent abuse. The main thing you need to worry about is Section 304 of the tax code, which specifically addresses sales between commonly controlled corporations. If you control both corporations, the IRS may recharacterize your sale proceeds as a dividend rather than capital gains. They look at these transactions very carefully for economic substance. You also need to consider basis issues. Your basis in Corp B affects your gain recognition. Additionally, there are potential accumulated earnings tax concerns if Corp A is holding excess cash without a legitimate business purpose.

•This makes sense, but I'm still confused about Section 304. If I'm selling my shares of Corp B to Corp A, how exactly does the IRS determine if it should be treated as a dividend vs capital gain? Is there a specific ownership percentage that triggers this? Also, what kind of documentation would I need to demonstrate "economic substance" to avoid problems?

•Section 304 applies when one corporation acquires stock of another corporation from a controlling shareholder (generally someone who owns 50% or more of either corporation). In this case, if you control both corporations, the transaction falls squarely within Section 304. The IRS determines dividend vs. capital gain treatment based on the relationship between the parties and the business purpose. To demonstrate economic substance, you need legitimate business reasons for the transaction beyond tax savings. This could include operational synergies, expansion plans, or resource consolidation. You should document these reasons in corporate minutes, business plans, and valuation reports prepared by independent third parties. Having a substantive business purpose is critical - if the only reason for the transaction is to extract cash, the IRS will likely recharacterize it.

I went through something similar last year with my construction businesses and found https://taxr.ai incredibly helpful for analyzing this exact scenario. I had two C Corps - one for residential projects and one for commercial - and was looking to consolidate. What I discovered is that the devil is really in the details with these corp-to-corp sales. The service helped me identify several issues I hadn't considered, including potential Section 304 implications the previous commenter mentioned and accumulated earnings tax risks. They analyzed my specific corporate structures and provided a detailed report showing various scenarios and tax implications. The valuation component was especially important - you need to establish fair market value for Corp B through a defensible methodology, which taxr.ai helped walk me through.

•Did they actually help with the valuation itself? I thought most tax services just give general advice but don't actually help determine what your business is worth. That's usually a separate specialized service, right?

•I'm skeptical about online tax tools for something this complex. How detailed was their analysis? Did they just give general information or did they actually review your specific corporate documents and ownership structures?

•They didn't perform the actual valuation themselves, but they provided a comprehensive framework for valuation approaches suitable for my specific situation and identified which documentation would be needed to support the valuation for tax purposes. This guidance helped me work efficiently with a business appraiser to get the valuation done properly. Their analysis was surprisingly detailed - I uploaded my corporate formation documents, financial statements, and ownership information, and they examined the specific relationships between my entities. They identified that my situation had particular risks under Section 304 and suggested specific documentation I should prepare to demonstrate business purpose. They didn't just provide generic advice - they flagged issues specific to my corporate structure and transaction.

I was skeptical about using an online service for something as complex as a corporation-to-corporation sale, but after my conversation here, I decided to give https://taxr.ai a try. I'm glad I did because my situation was more complicated than I initially thought. My main concern was ensuring the transaction wouldn't be reclassified as a dividend, and they provided a detailed analysis of exactly how Section 304 would apply to my specific ownership structure. What I found especially valuable was their explanation of "boot" considerations in my situation (where part of the transaction includes non-stock compensation) and how that affected the tax treatment. They also flagged potential accumulated earnings tax issues I hadn't considered and suggested documentation strategies to demonstrate legitimate business needs for retained earnings. The report included case references where similar transactions were challenged by the IRS - super helpful in understanding the risks.

If you're considering this corp-to-corp strategy, one thing nobody's mentioned is that you'll probably need to talk to the IRS about it at some point. I tried calling them for clarification on a similar corporate restructuring last year, and it was IMPOSSIBLE to get through. Would spend hours on hold only to get disconnected. I finally used https://claimyr.com and got through to an actual IRS agent in about 15 minutes. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The agent walked me through some important considerations for my corporate sale transaction, including documentation requirements and potential red flags. Worth every penny because I learned my original plan would have triggered some serious scrutiny. They helped me understand how to properly document business purpose for the transaction.

•Wait how does this work? Are they somehow jumping the IRS phone queue for you? That sounds kinda sketchy tbh.

•Yeah right. There's no way to "skip the line" with the IRS. They probably just keep calling over and over like anyone could do themselves. I've tried everything to get through to them and nothing works. I highly doubt this service does anything special.

•It's not sketchy at all - they use an automated system that navigates the IRS phone tree and holds your place in line. When an agent actually answers, the system calls your phone and connects you directly with the IRS agent. You're not skipping the line - just avoiding having to personally sit on hold for hours. I was definitely skeptical too before trying it. What convinced me was that I wasn't paying for any tax advice from them - just the connection service. The actual tax guidance came directly from the IRS agent, who confirmed several important points about Section 304 transactions and documentation requirements. I was able to ask specific questions about my situation and got official answers instead of guessing or relying on internet forums.

I need to publicly eat my words about Claimyr. After posting my skeptical comment, I was still desperate to talk to the IRS about my C Corp restructuring questions, so I reluctantly tried it. I assumed it would be a waste of money, but within 20 minutes I was talking to an actual IRS corporate tax specialist. I explained my plan to sell one corporation to another to extract cash, and she immediately identified several compliance issues I would have faced. The specialist explained that in my case, Section 304 would definitely apply since I own both corporations, and she outlined specific documentation I would need to avoid having the entire transaction reclassified as a dividend. She also mentioned that these transactions often trigger closer examination and gave me tips on how to properly document everything. Saved me from what would have been a costly mistake and potentially an audit. Sometimes it's worth admitting when you're wrong!

Something important nobody's mentioned yet: valuation is CRITICAL in these transactions. If you sell Corp B to Corp A for significantly more than fair market value, the IRS could claim the excess is actually a disguised dividend. You really need an independent valuation of Corp B to justify the price. I screwed this up a few years ago and ended up with a huge headache during an audit. They questioned everything and ultimately recharacterized a big chunk of my payment as dividend income + penalties.

•What kind of valuation did you end up getting? Did you use a specific business valuation company or accountant? And roughly how much did it cost if you don't mind sharing?

•I originally tried to cut corners with a valuation from my regular accountant, which was the big mistake. After the audit started, I hired a certified business appraiser with credentials in business valuation (look for CVA, ABV or ASA designations) who specialized in closely-held companies. A proper valuation for a small-to-medium corporation typically runs between $5,000-$12,000 depending on complexity. Seems expensive but it's much cheaper than what I ended up paying in taxes, penalties and professional fees during the audit. The key is finding someone who does these regularly for tax purposes specifically, not just for business sales. They understand what documentation the IRS expects and how to defend the methodology they use.

Has anybody considered the step-transaction doctrine in this scenario? The IRS might look at the before/after ownership and conclude this was just a scheme to extract cash while avoiding dividend treatment.

Savannah Glover
•Exactly right. The step-transaction doctrine is a huge risk here. If the primary purpose is just extracting cash from Corp A, the IRS will likely collapse the steps and treat it as a dividend. You need an independent business purpose for why Corp A is acquiring Corp B.

One aspect that hasn't been fully explored is the timing of this transaction. If you're planning to do this near year-end or in conjunction with other corporate activities, the IRS will scrutinize the timing for tax avoidance motives. I'd also recommend documenting legitimate operational reasons for the acquisition well in advance. For example, if Corp B provides services or products that Corp A actually uses, or if there are genuine economies of scale from combining operations, make sure this is documented in board resolutions and business plans before executing the transaction. Another consideration: if Corp B has net operating losses or other tax attributes, there are complex rules under Sections 382 and 383 that could limit their use after the acquisition. This might actually reduce the overall tax efficiency of the structure. Have you considered whether a redemption under Section 302 might be a cleaner approach? If structured properly as a "substantially disproportionate" or "complete termination" redemption, you could potentially achieve capital gains treatment without the complexity of maintaining two corporate entities.

•This is really helpful advice about timing and documentation. I'm curious about the Section 302 redemption option you mentioned - could you elaborate on how that would work compared to the corp-to-corp sale? What would need to happen for a redemption to qualify as "substantially disproportionate"? And would that still allow me to extract cash from Corp A while maintaining some level of ownership, or would I need to give up control entirely? Also, regarding the NOL limitations under Sections 382/383 - if Corp B doesn't have significant losses, would those rules still be a concern, or are they only triggered when there are tax attributes to preserve?
