Converting C corp to S corp to avoid double taxation on appreciated rental property and land
So I've been digging into an interesting tax situation with our family business. We've had this old C corporation for years that owns a rental building and two vacant lots. The property values have skyrocketed since we acquired them, but the business itself doesn't generate much cash flow aside from the rental income. I've been researching options and it seems like there might be a smart tax move here. From what I understand, we could convert the C corp to an S corp, but we'd need to wait 5 years before selling any assets that were held during the conversion. Otherwise, there's some kind of hefty tax penalty. The potential upside seems huge though. If we convert to an S corp, wait the 5 years, then sell these properties, we'd only pay capital gains tax rates on the appreciation due to the pass-through taxation of S corps. That seems WAY better than what we'd pay under the C corp structure, where we'd get hit with the 21% corporate tax AND then individual tax rates on dividends when we try to get the money out. Has anyone done something like this? Am I missing anything major? The tax savings could be substantial given how much these properties have appreciated. Just want to make sure this is a legitimate strategy before we start the process.

You're on the right track with this strategy, but there are several important factors to consider before proceeding. The approach you're describing takes advantage of the built-in gains tax rules. When a C corporation converts to an S corporation, there's a 5-year recognition period where the "built-in gains" (BIG) that existed at the time of conversion are still subject to corporate-level tax if the assets are sold during that period. After the 5-year waiting period, you can potentially avoid the double taxation scenario. However, you need to be aware of a few critical details: 1) You'll need a proper valuation of the properties at the time of conversion to establish the built-in gain amount. 2) The S corporation will still need to meet all eligibility requirements (100 or fewer shareholders, only certain types of shareholders, one class of stock, etc.). 3) There may be state tax implications that differ from federal treatment. 4) The passive investment income rules for S corporations could be an issue if rental income exceeds certain thresholds. This strategy can work well, but I'd strongly recommend working with a tax attorney or CPA who specializes in business entity conversions to ensure all aspects are properly addressed.

•Thanks for the detailed response! The valuation requirement makes sense - I'm guessing we'd need a formal appraisal of all properties at conversion time? Also, I'm a bit concerned about the passive income rules you mentioned. The rental income is pretty much all we have. Would that create problems for maintaining S corp status after conversion?

•Yes, you would need a formal appraisal from a qualified appraiser to establish the fair market value at conversion. This documentation is crucial in case of an audit, as the burden of proof falls on you to demonstrate the value at conversion time. Regarding passive income, this is primarily a concern if your S corporation has accumulated earnings and profits (E&P) from its C corporation days. If that's the case, and if passive investment income exceeds 25% of gross receipts for three consecutive tax years, the S election could be terminated. Additionally, there's a tax on excess net passive income if certain conditions are met. You may want to consider strategies to eliminate the accumulated E&P, such as making dividend distributions before converting.

After struggling with a similar situation last year, I discovered a great service that helped me navigate this exact scenario. I had a C corp with significant appreciated assets and was looking at conversion options. I was getting conflicting advice about the BIG tax implications and qualification requirements until I found https://taxr.ai - they analyzed all my corporate docs and provided a comprehensive tax strategy report outlining the exact steps needed for conversion. Their analysis showed me several angles I hadn't considered about the passive income limitations and how to properly document the property valuations. What I found particularly helpful was their detailed timeline for implementing the conversion while minimizing risk. They even pointed out a potential issue with my existing shareholder structure that would have disqualified the S election if not corrected first.

•How long did the whole process take with them? I'm curious because we're on a bit of a timeline with potentially selling one of our properties within the next 6-7 years, so we'd need to start the conversion ASAP if we're going to go that route.

•Was this an expensive service? I've been burned before by "tax specialists" who charge thousands and then just give generic advice I could've googled. Does taxr.ai actually provide customized strategies or is it more of a template approach?

•The entire process took about 3 weeks from submitting my documents to receiving the full analysis and implementation plan. They were very thorough, and the timeline they created accounted for the 5-year recognition period, which sounds perfect for your 6-7 year selling horizon. Their service was extremely customized to my situation. Unlike the generic "tax specialists" I'd worked with before, they analyzed my specific corporate structure, property holdings, and financial statements to develop a tailored strategy. They identified several issues unique to my situation that would have caused problems with the S election, including a special provision in my corporate bylaws that inadvertently created a second class of stock which would have disqualified the conversion.

I wanted to follow up on my skeptical question about taxr.ai. I decided to give them a try after my accountant was giving me conflicting information about our C to S corp conversion options. I'm honestly surprised by how detailed their analysis was. They found a potential issue with our operating agreement that could have been interpreted as creating different classes of shares, which would have killed our S corp election. They also provided a comprehensive valuation strategy for our commercial properties that satisfied IRS requirements without breaking the bank on multiple full appraisals. What really impressed me was their customized strategy for handling our accumulated E&P to avoid the passive income limitations after conversion. They outlined a specific dividend and reinvestment plan that would clean up our balance sheet before conversion. Seriously saved us from what could have been a costly mistake several years down the road.

If you're planning this C to S conversion strategy, one thing nobody mentioned yet is how ridiculously hard it can be to get a human at the IRS to answer questions about your filing status during/after conversion. I spent WEEKS trying to confirm our conversion was processed correctly last year. I eventually used https://claimyr.com to get through to an IRS agent in about 20 minutes after wasting days on hold. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c I had questions about our Form 2553 (Election by a Small Business Corporation) that nobody could answer, and I needed to make sure everything was processed correctly before making any major business decisions. The service got me through to someone who could actually pull up our file and confirm the election was properly recorded and give me the effective date.

•Wait, how does this actually work? Are they just calling the IRS for you? Why would that be any faster than me calling myself?

•I'm calling BS on this. Nobody gets through to the IRS in 20 minutes these days. The wait times are insane - I've literally been on hold for 3+ hours multiple times this year. If they have some "special number" or whatever, it's probably not legitimate.

•They use an automated system that navigates the IRS phone tree and waits on hold for you. When an agent finally picks up, you get a call back and are connected immediately. You're not doing anything different than calling yourself, just not wasting hours of your life on hold. The system basically monitors the hold music and when it detects a human voice, it immediately calls you to connect. It's completely legitimate - you're still talking directly to actual IRS agents through the official channels, just without the hold time. It's especially useful for complex business tax situations like entity conversions where you really need to speak with someone to confirm everything is being processed correctly.

I need to eat my words about Claimyr from my previous comment. After another frustrating 2-hour hold with the IRS trying to confirm our S election status, I decided to try the service out of desperation. It actually worked exactly as described. I submitted my request in the afternoon, and about 40 minutes later (which I spent doing actual productive work instead of listening to hold music), I got a call connecting me to an IRS representative. I was able to confirm our S election effective date and get clarification on some questions about our first year filing requirements. For anyone dealing with the C to S conversion process, being able to actually talk to the IRS to confirm your paperwork is properly filed is incredibly valuable. Our accountant had submitted the Form 2553, but it turns out there was a small issue that could have invalidated our election if not caught early. Definitely worth it just for the peace of mind.

Something nobody's mentioned yet is the potential alternative of just doing a straight property sale from the C corp and then liquidating the corporation. Yes, you'll have double taxation, but have you actually run the numbers against the S corp conversion strategy? Remember that with the S corp route, you're still paying tax on the FULL appreciation of the property when you sell after the 5-year period. You're just avoiding the double taxation element. But there are costs to maintaining the corporation for 5+ years too. Depending on your specific circumstances and the amount of appreciation, it might still be worth considering a direct sale and liquidation rather than waiting 5 years. I'd recommend modeling both scenarios with actual numbers.

•That's a great point I hadn't fully considered. We do have significant carrying costs on these properties, plus the ongoing compliance costs of maintaining the corporation. Do you know if there's a general rule of thumb for when the wait-and-convert strategy makes more sense than just taking the tax hit upfront? Our properties have probably appreciated about 70% since acquisition, which was around 15 years ago.

•There's no simple rule of thumb since it depends on too many variables: the exact amount of appreciation, your personal tax rates, the corporation's tax rate, ongoing maintenance costs, opportunity costs of waiting 5 years, and potential future appreciation during that waiting period. In your case with 70% appreciation over 15 years, you'd need to model both scenarios with precise numbers. Remember that during the 5-year waiting period, the properties could continue to appreciate, which would be taxed at the more favorable pass-through rates after conversion. You also need to factor in the time value of money - getting proceeds now might be worth the higher tax cost depending on what investment opportunities you have.

Just a heads up on something that surprised us during our C to S conversion last year - the Accumulated Adjustments Account (AAA) tracking became really important. After conversion, you'll need to carefully track AAA which is basically the post-conversion retained earnings that have already been taxed at the shareholder level. When you eventually distribute proceeds from property sales, the ordering rules for distributions can get tricky between AAA, accumulated E&P from the C corp days, and other sources. Our accountant messed this up initially and it almost resulted in some distributions being incorrectly taxed as dividends when they should have been tax-free returns of already-taxed income.

•Exactly this! We converted 4 years ago and are approaching the end of our BIG period. The accounting requirements are WAY more complex for a converted S corp than they were for our C corp. We have to carefully track multiple buckets of money and their tax characteristics.

One thing I haven't seen mentioned yet is the potential impact of state taxes on this strategy. While the federal tax benefits of converting from C corp to S corp are well-documented, some states don't recognize S corp elections or have their own built-in gains taxes that could significantly impact your overall tax savings. For example, some states will continue to tax the entity as a C corporation even after federal S election, which could eliminate much of the benefit you're hoping to achieve. Other states have their own recognition periods or different rules for built-in gains. Given that you're dealing with real estate, you'll also want to consider whether your state has any special provisions for real estate held in corporate entities. Some states have additional taxes or fees for corporations holding real property that could affect your cost-benefit analysis. I'd strongly recommend getting state-specific advice from a tax professional familiar with your jurisdiction before moving forward with the conversion. The federal tax savings could be completely offset by unexpected state tax consequences.
